The specific aim of this study was to summarize the viewpoints of the Resident and Associate Society of the American College of Surgeons (RAS-ACS) membership regarding current training and quality of life-related issues prior to implementation of the new duty-hour guidelines. The goal was to gain insight of the members that may be useful to recruit and guide the future training of surgical residents. An Internet-based survey was developed to evaluate the viewpoints of RAS-ACS. The survey was administered by Esurveymaker.com via the ACS Web page from 2000 to 2003. RAS-ACS member participation was voluntary and anonymous. Analyses were performed to determine the frequency of response for each survey item. Two hundred thirty-five members completed the survey representing 5 per cent of RAS-ACS. Eighty-four per cent were general surgery residents. Personal satisfaction (64%) and mentorship (49%) were top factors for respondents to pursue surgical training; discussion with colleagues and future income was less important. Forty-five per cent reported that job performance was their most important concern during residency. A rewarding surgical career and family life were ranked as the most important expectations. Eighty-six per cent reported that they were satisfied with their residency, and 66 per cent reported that work hours should be limited. Personal satisfaction and mentorship were critical factors for members of the RAS-ACS to seek surgical training. Although most of the members report that work hours should be limited, an overwhelming majority reports satisfaction with surgical training prior to institution of the new duty-hour guidelines. Further emphasis on mentorship and work-hour reform may be beneficial in recruiting medical students into surgical residencies.

Surgeons and nurses sometimes perceive a high workload on the surgical wards, which may influence admission decisions and staffing policy. This study aimed to explore the relative contribution of various patient and care characteristics to the perceived patients' care intensity and whether differences exist in the perception of surgeons and nurses. We invited surgeons and surgical nurses in the Netherlands for a conjoint analysis study through internet and e-mail invitations. They rated 20 virtual clinical scenarios regarding patient care intensity on a 10-point Likert scale. The scenarios described patients with 5 different surgical conditions: cholelithiasis, a colon tumor, a pancreas tumor, critical leg ischemia, and an unstable vertebral fracture. Each scenario presented a mix of 13 different attributes, referring to the patients' condition, physical symptoms, and admission and discharge circumstances. A total of 82 surgeons and 146 surgical nurses completed the questionnaire, resulting in 4560 rated scenarios, 912 per condition. For surgeons, 6 out of the 13 attributes contributed significantly to care intensity: age, polypharmacy, medical diagnosis, complication level, ICU-stay and ASA-classification, but not multidisciplinary care. For nurses, the same six attributes contributed significantly, but also BMI, nutrition status, admission type, patient dependency, anxiety or delirium during hospitalization, and discharge type. Both professionals ranked 'complication level' as having the highest impact. The differences between surgeons and nurses on attributes contributing to care intensity may be explained by differences in professional roles and daily work activities. Surgeons have a medical background, including technical aspects of their work and primary focus on patient curation. However, nurses are focused on direct patient care, i.e., checking vital functions, stimulating self-care and providing woundcare. Surgeons and nurses differ in their perception of

Effective physician-patient communication is a critical component of a clinical practice and in order to achieve optimal patient outcomes. We aimed to investigate indirect effects of physician-patient communication by examining the relationship between a physician-patient mismatch in perceived outcomes and content in the medical record's clinical note. We compared patient records whose perceived subjective assessment of surgery outcomes agreed or disagreed with the surgeon's perception of that outcome (Subjective Disagreement). This study included 172 spine surgery patients at a teaching hospital. Patient-reported outcomes included the Oswestry Disability Index; the Short-Form 36; and a Visual Analogue Scale items for leg and back pain. We content-analyzed the clinical note in the medical record, and used logistic regression to evaluate predictors of Subjective Disagreement (n = 41 disagreed vs. 131 agreed). Patient and surgeon agreed in 76% of cases and disagreed in 24% of cases. Patients who assessed their outcome worse than their surgeons tended to be less educated and involved in litigation. They also tended to report worsened mental health and leg pain. Content analysis revealed group differences in surgeon communication patterns in the chart notes related to how symptom change was emphasized, how follow-up was described, and a specific word reference. Specifically, disagreement was predicted by using "much" to emphasize the findings and noting long-term prognosis. Agreement was predicted by use of positive emphasis terms, having an "as-needed" follow-up plan, and using "happy" in the chart note. The nature of measuring outcomes of surgery is based on patient perception. In surgeon-patient perspective mismatches, patient factors may serve as barriers to improvement. Worsened change on patient-reported mental health may be an independent factor which colors the patient's general perceptions. This aspect of treatment may be missed by the spine surgeon. Chart

While investigators have employed a number of different tools to measure the effect of fatigue on surgical performance, the use of the surgical simulator has been increasingly implemented for this purpose. The goal of this paper is to review the published literature to achieve a better understanding of evaluation of fatigue on performance as studied with surgical simulators. Methods: A PubMed and Cochrane search was conducted using the search terms “simulator”, “surgery”, and “fatigue”. In total, 50 papers were evaluated, and 20 studies were selected after application of exclusion criteria. Articles were excluded if they did not use the simulator to assess the impact of fatigue on surgeon performance. Systematic reviews and case reports were also excluded. Results: Surgeon fatigue led to a consistent decline in cognitive function in six studies. Technical skills were evaluated in 18 studies, and a detrimental impact was reported in nine studies, while the remaining nine studies showed either no change or positive results with regard to surgical skills after experience of fatigue. Two pharmacological intervention studies reversed the detrimental impact of fatigue on cognitive function, but no change or a worsening effect was recognized for technical skills. Conclusion: Simulators are increasingly being used to evaluate the impact of fatigue on the surgeon's performance. With regard to the impact of fatigue in this regard, studies have demonstrated a consistent decline in cognitive function and mixed outcomes for technical skills.

Risk factors for unplanned readmission within 30 days after pediatric neurosurgery: a nationwide analysis of 9799 procedures from the American College of Surgeons National Surgical Quality Improvement Program.
Sherrod, Brandon A; Johnston, James M; Rocque, Brandon G
OBJECTIVE Hospital readmission rate is increasingly used as a quality outcome measure after surgery. The purpose of this study was to establish, using a national database, the baseline readmission rates and risk factors for patient readmission after pediatric neurosurgical procedures. METHODS The American College of Surgeons National Surgical Quality Improvement Program-Pediatric database was queried for pediatric patients treated by a neurosurgeon between 2012 and 2013. Procedures were categorized by current procedural terminology (CPT) code. Patient demographics, comorbidities, preoperative laboratory values, operative variables, and postoperative complications were analyzed via univariate and multivariate techniques to find associations with unplanned readmissions within 30 days of the primary procedure. RESULTS A total of 9799 cases met the inclusion criteria, 1098 (11.2%) of which had an unplanned readmission within 30 days. Readmission occurred 14.0 ± 7.7 days postoperatively (mean ± standard deviation). The 4 procedures with the highest unplanned readmission rates were CSF shunt revision (17.3%; CPT codes 62225 and 62230), repair of myelomeningocele > 5 cm in diameter (15.4%), CSF shunt creation (14.1%), and craniectomy for infratentorial tumor excision (13.9%). The lowest unplanned readmission rates were for spine (6.5%), craniotomy for craniosynostosis (2.1%), and skin lesion (1.0%) procedures. On multivariate regression analysis, the odds of readmission were greatest in patients experiencing postoperative surgical site infection (SSI; deep, organ/space, superficial SSI, and wound disruption: OR > 12 and p 10 days (OR 1.411, p = 0.010), oxygen supplementation (OR 1.645, p = 0.010), nutritional support (OR 1.403, p = 0.009), seizure disorder (OR 1.250, p = 0.021), and longer operative time (per hour increase, OR 1.059, p = 0.029). CONCLUSIONS This study may aid in identifying patients at risk for unplanned readmission following pediatric neurosurgery

The widespread adoption of laparoscopic surgery has put new physical demands on the surgeon leading to increased musculoskeletal disorders and injuries. Shoulder, back, and neck pains are among the most common complaints experienced by laparoscopic surgeons. Here, we evaluate the feasibility and efficacy of a non-intrusive progressive arm support exosuit worn by surgeons under the sterile gown to reduce pain and fatigue during surgery. This is a prospective randomized crossover study approved by the Internal Review Board (IRB). The study involves three phases of testing. In each phase, general surgery residents or attendings were randomized to wearing the surgical exosuit at the beginning or at the crossover point. The first phase tests for surgeon manual dexterity wearing the device using the Minnesota Dexterity test, the Purdue Pegboard test, and the Fundamentals of Laparoscopic Surgery (FLS) modules. The second phase tests the effect of the device on shoulder pain and fatigue while operating the laparoscopic camera. The third phase rates surgeon experience in the operating room between case-matched operating days. Twenty subjects were recruited for this study. Surgeons had the similar dexterity scores and FLS times whether or not they wore the exosuit (p value ranges 0.15-0.84). All exosuit surgeons completed 15 min of holding laparoscopic camera compared to three non-exosuit surgeons (p < 0.02). Exosuit surgeons experienced significantly less fatigue at all time periods and arm pain (3.11 vs 5.88, p = 0.019) at 10 min. Surgeons wearing the exosuit during an operation experienced significant decrease in shoulder pain and 85% of surgeons reported some form of pain reduction at the end of the operative day. The progressive arm support exosuit can be a minimally intrusive device that laparoscopic surgeons wear to reduce pain and fatigue of surgery without significantly interfering with operative skills or manual dexterity.

Approximately 20 percent of general surgery residents never complete their original residency programs. The psychological, programmatic, and financial costs for this attrition are substantial for both the residents, who spend valuable time and money pursuing incompatible career paths, and the residency programs, which also lose valuable time and money invested in these residents. There is a large amount of information in the field about the performance dimensions and skill sets of surgeons and surgical residents. To date, however, no research has been conducted on important process and content dimensions, which are critical in determining good person-job fit. A research team from the Department of Psychology at Arizona State University and Maricopa Medical Center conducted descriptive research to determine the work-related personality and interest variables of attending surgeons and surgical residents. Sixty-three surgical residents and 27 attending/teaching surgeons completed 2 sections (interests and personality scales) of the World of Work Inventory Online (WOWI Online). This multidimensional assessment was offered to all attending/teaching surgeons and surgical residents at Maricopa Medical Center. All members of the Department of Surgery participated in the trial. Based on the attending/teaching and high-performing resident profiles, a stable interest and personality profile emerged, which highlights the unique characteristics necessary to identify those who would be most satisfied with and suitable for work as surgeons. The profiles of the attending/teaching surgeons and the high-performing residents were similar. This contrasted with the interest and personality profiles of low-performing residents. The differences in the 2 groups' profiles provide insight into low performance and possible incompatibility with surgical residency, and possibly with general surgery as a profession choice. The WOWI Online assessment tool provides a stable profile of successful

As new technology is developed and scientific evidence demonstrates strategies to improve the quality of care, it is essential that surgeons keep current with their skills. Rural surgeons need efficient and targeted continuing medical education that matches their broader scope of practice. Developing such a program begins with an assessment of the learning needs of the rural surgeon. The aim of this study was to assess the learning needs considered most important to surgeons practicing in rural areas. A needs assessment questionnaire was administered to surgeons practicing in rural areas. An additional gap analysis questionnaire was administered to registrants of a skills course for rural surgeons. Seventy-one needs assessment questionnaires were completed. The self-reported procedures most commonly performed included laparoscopic cholecystectomy (n = 44), hernia repair (n = 42), endoscopy (n = 43), breast surgery (n = 23), appendectomy (n = 20), and colon resection (n = 18). Respondents indicated that they would most like to learn more skills related to laparoscopic colon resection (n = 16), laparoscopic antireflux procedures (n = 6), laparoscopic common bile duct exploration/ERCP (n = 5), colonoscopy/advanced techniques and esophagogastroscopy (n = 4), and breast surgery (n = 4). Ultrasound, hand surgery, and leadership and communication were additional topics rated as useful by the respondents. Skills course participants indicated varying levels of experience and confidence with breast ultrasound, ultrasound for central line insertion, hand injury, and facial soft tissue injury. Our results demonstrated that surgeons practicing in rural areas have a strong interest in acquiring additional skills in a variety of general and subspecialty surgical procedures. The information obtained in this study may be used to guide curriculum development of further postgraduate skills courses targeted to rural surgeons. Copyright © 2013 American College of Surgeons.

Abstract Purpose: Selecting a healthcare provider is often a complicated process. Many factors appear to govern the decision as to how to select the provider in the patient–provider relationship. While the possibility of changing primary care physicians or specialists exists, decisions regarding surgeons are immutable once surgery has been performed. This study is an attempt to assess the importance attached to various factors involved in selecting a surgeon to perform gender affirmation surgery (GAS). It was hypothesized that owing to the intimate nature of the surgery, the expense typically involved, the emotional meaning attached to the surgery, and other variables, decisions regarding choice of surgeon for this procedure would involve factors other than those that inform more typical healthcare provider selection or surgeon selection for other plastic/reconstructive procedures. Methods: Questionnaires were distributed to individuals who had undergone GAS and individuals who had undergone elective plastic surgery to assess decision-making. Results: The results generally confirm previous findings regarding how patients select providers. Conclusion: Choosing a surgeon to perform gender-affirming surgery is a challenging process, but patients are quite rational in their decision-making. Unlike prior studies, we did not find a preference for gender-concordant surgeons, even though the surgery involves the genital area. Providing strategies and resources for surgical selection can improve patient satisfaction. PMID:29159303

In addition to technical expertise, surgical competence requires effective non-technical skills to ensure patient safety and maintenance of standards. Recently the Royal Australasian College of Surgeons implemented a new Surgical Education and Training (SET) curriculum that incorporated non-technical skills considered essential for a competent surgeon. This study sought to compare the non-technical skills of experienced surgeons who completed their training before the introduction of SET with the non-technical skills of more recent trainees. Surgical trainees and experienced surgeons undertook a simulated scenario designed to challenge their non-technical skills. Scenarios were video recorded and participants were assessed using the Non-Technical Skills for Surgeons (NOTSS) scoring system. Participants were divided into subgroups according to years of experience and their NOTSS scores were compared. For most NOTSS elements, mean scores increased initially, peaking around the time of Fellowship, before decreasing roughly linearly over time. There was a significant downward trend in score with increasing years since being awarded Fellowship for six of the 12 NOTSS elements: considering options (score -0·015 units per year), implementing and reviewing decisions (-0·020 per year), establishing a shared understanding (-0·014 per year), setting and maintaining standards (-0·024 per year), supporting others (-0·031 per year) and coping with pressure (-0·015 per year). The drop in NOTSS score was unexpected and highlights that even experienced surgeons are not immune to deficiencies in non-technical skills. Consideration should be given to continuing professional development programmes focusing on non-technical skills, regardless of the level of professional experience. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

For ease of use and to aid precision, left-handed instruments are invaluable to the left-handed surgeon. Although they exist, they are not available in many surgical centres. As a result, most operating theatre staff (including many left-handers) have little knowledge of their value or even application. With specific reference to cardiac surgery, this article addresses the ways in which they differ, why they are needed and what is required - with tips on use.

Most residents in training today are in focused on their training, and the thoughts of changing the structure of residencies and fellowships is something that they are ambivalent about or have never heard anything about. The small minority who are vocal on these issues represent an activist group supporting change. This group is very vocal and raises many of the excellent questions we have examined. In discussion with residents, some feel that shortened training will help with the financial issues facing residents. However, many people today add additional years to their training with research years or "super" fellowships. The residents demonstrate that they want to get the skill sets that they desire despite the added length of training. This is unlikely to change even if the minimum number of years of training changes with the evolution of tracked training programs. Medical students, in the Resident and Associate Society of the American College of Surgeons survey, did not indicate that shortened training would have an affect on decision to pursue or not pursue a surgical career. If the focus of these changes is to encourage medical students to pursue a residency in surgical specialties, we may need to look at other options to increase medical student interest. Medical students indicated that lifestyle issues, types of clinical problems, stress-related concerns, and interactions with the surgical faculty were far more important in their decision to enter a surgical specialty than work hours or duration of training. If we are to make a difference in the quality and quantity of applicants for surgical residencies, then changes in the structure of residencies do not seem to be the most effective way to accomplish this. We should possibly focus more on faculty and medical student interaction and the development of positive role models for medical students to see surgeons with attractive practices that minimize some of the traditionally perceived negative stereotypes

To examine trends in and determinants of the use of different procedures for treatment of cubital tunnel syndrome. We performed a retrospective cross-sectional analysis of the Healthcare Cost and Utilization Project Florida State Ambulatory Surgery Database for 2005 to 2012. We selected all patients who underwent in situ decompression, transposition, or other surgical treatments for cubital tunnel syndrome. We tested trends in the use of these techniques and performed a multivariable analysis to examine associations among patient characteristics, surgeon case volume, and the use of different techniques. Of the 26,164 patients who underwent surgery for cubital tunnel syndrome, 80% underwent in situ decompression, 16% underwent transposition, and 4% underwent other surgical treatment. Over the study period, there was a statistically significant increase in the use of in situ release and a decrease in the use of transposition. Women and patients treated by surgeons with a higher cubital tunnel surgery case volume underwent in situ release with a statistically higher incidence than other techniques. In Florida, surgeon practice reflected the widespread adoption of in situ release as the primary treatment for cubital tunnel syndrome, and its relative incidence increased during the study period. Patient demographics and surgeon-level factors influenced procedure selection. Therapeutic III. Copyright © 2015 American Society for Surgery of the Hand. Published by Elsevier Inc.

Consultant Outcomes Publication (COP) has the longest history in cardiothoracic surgery, where it was introduced in 2005. Subsequently COP has been broadened to include all surgical specialties in NHS England in 2013-14. The Association of Surgeons in Training (ASiT) fully supports efforts to improve patient care and trust in the profession and is keen to overcome potential unintended adverse effects of COP. Identification of these adverse effects is the first step in this process: Firstly, there is a risk that COP may lead to reluctance by consultants to provide trainees with the necessary appropriate primary operator experience to become skilled consultant surgeons for the future. Secondly, COP may lead to inappropriately cautious case selection. This adjusted case mix affects both patients who are denied operations, and also limits the complexity of the case mix to which surgical trainees are exposed. Thirdly, COP undermines efforts to train surgical trainees in non-technical skills and human factors, simply obliterating the critical role of the multidisciplinary team and organisational processes in determining outcomes. This tunnel vision masks opportunities to improve patient care and outcomes at a unit level. It also misinforms the public as to the root causes of adverse events by failing to identify care process deficiencies. Finally, for safe surgical care, graduate retention and morale is important - COP may lead to high calibre trainees opting out of surgical careers, or opting to work abroad. The negative effects of COP on surgical training and trainees must be addressed as high quality surgical training and retention of high calibre graduates is essential for excellent patient care.

The prevention of medical and surgical harm remains an important public health problem despite increased awareness and implementation of safety programs. Successful introduction and maintenance of surgical safety programs require both surgeon leadership and collaborative surgeon-hospital alignment. Documentation of success of such surgical safety programs in orthopaedic practice is limited. We describe the scope of orthopaedic surgical patient safety issues, define critical elements of orthopaedic surgical safety, and outline leadership roles for orthopaedic surgeons needed to establish and sustain a culture of safety in contemporary healthcare systems. We identified the most common causes of preventable surgical harm based on adverse and sentinel surgical events reported to The Joint Commission. A comprehensive literature review through a MEDLINE(®) database search (January 1982 through April 2012) to identify pertinent orthopaedic surgical safety articles found 14 articles. Where gaps in orthopaedic literature were identified, the review was supplemented by 22 nonorthopaedic surgical references. Our final review included 36 articles. Six important surgical safety program elements needed to eliminate preventable surgical harm were identified: (1) effective surgical team communication, (2) proper informed consent, (3) implementation and regular use of surgical checklists, (4) proper surgical site/procedure identification, (5) reduction of surgical team distractions, and (6) routine surgical data collection and analysis to improve the safety and quality of surgical patient care. Successful surgical safety programs require a culture of safety supported by all six key surgical safety program elements, active surgeon champions, and collaborative hospital and/or administrative support designed to enhance surgical safety and improve surgical patient outcomes. Further research measuring improvements from such surgical safety systems in orthopaedic care is needed.

The American College of Surgeons National Surgical Quality Improvement Program is well recognized in surgical quality measurement and is used widely in research. Recent calls to make it a platform for national public reporting and pay-for-performance initiatives highlight the importance of understanding which types of hospitals elect to participate in the program. Our objective was to compare characteristics of hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program to characteristics of nonparticipating US hospitals. The 2013 American Hospital Association and Centers for Medicare & Medicaid Services Healthcare Cost Report Information System datasets were used to compare characteristics and operating margins of hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program to those of nonparticipating hospitals. Of 3,872 general medical and surgical hospitals performing inpatient surgery in the United States, 475 (12.3%) participated in the American College of Surgeons National Surgical Quality Improvement Program. Participating hospitals performed 29.0% of all operations in the United States. Compared with nonparticipating hospitals, American College of Surgeons National Surgical Quality Improvement Program hospitals had a higher mean annual inpatient surgical case volume (6,426 vs 1,874; P quality-related accreditations (P Quality Improvement Program had established surgical quality improvement collaboratives. The American College of Surgeons National Surgical Quality Improvement Program hospitals are large teaching hospitals with more quality-related accreditations and financial resources.

Introduction: The aim of the present study is to develop a heuristic that could replace the surgeon's analysis for the decision on the operative approach of distal radius fractures based on simple fracture characteristics. Patients and methods: Five hundred distal radius fractures operated between 2011 and 2014 were analyzed for the surgeon's decision on the approach used. The 500 distal radius fractures were treated with open reduction and internal fixation through palmar, dorsal, and dorsopalmar approaches with 2.4 mm locking plates or underwent percutaneous fixation. The parameters that should replace the surgeon's analysis were the fractured palmar cortex, and the frontal and the sagittal split of the articular surface of the distal radius. Results: The palmar approach was used for 422 (84.4%) fractures, the dorsal approach for 39 (7.8%), and the combined dorsopalmar approach for 30 (6.0%). Nine (1.8%) fractures were treated percutaneously. The correlation between the fractured palmar cortex and the used palmar approach was moderate (r=0.464; p<0.0001). The correlation between the frontal split and the dorsal approach, including the dorsopalmar approach, was strong (r=0.715; p<0.0001). The sagittal split had only a weak correlation for the dorsal and dorsopalmar approach (r=0.300; p<0.0001). Discussion: The study shows that the surgical decision on the preferred approach is dictated through two simple factors, even in the case of complex fractures. Conclusion: When the palmar cortex is displaced in distal radius fractures, a palmar approach should be used. When there is a displaced frontal split of the articular surface, a dorsal approach should be used. When both are present, a dorsopalmar approach should be used. These two simple parameters could replace the surgeon's analysis for the surgical approach.
Full Text Available Aim. To analyze tears in sterile surgical gloves used by surgeons in the operating theatre of the Trauma and Orthopedic Surgery Department, Copernicus Memorial Hospital, Łódź, Poland Materials and Method. This study analyzes tears in sterile surgical gloves used by surgeons by ICD-9 and ICD-10 codes. 1,404 gloves were collected from 581 surgical procedures. All gloves were tested immediately following surgery using the test method described in Standard EN455–1 (each glove was inflated with 1,000 ± 50 ml of water and observed for leaks for 2–3 min.. Results. Analysis of tears took into consideration the role of medical personnel (operator, first assistant, second assistant during surgical procedure, the type of procedure according to ICD-9 and ICD-10 codes, and the elective or emergency nature of the procedure. The results of the study show that these factors have a significant influence on the risk of glove tears. Significant differences were observed in tear frequency and tear location depending on the function performed by the surgeon during the procedure. Conclusion. The study proved that the role performed by the surgeon during the procedure (operator, first assistant, second assistant has a significant influence on the risk of glove tearing. The role in the procedure determines exposure to glove tears. Implementing a double gloving procedure in surgical procedures or using single gloves characterized by higher tear resistance should be considered.

The amount of guidance provided by the attending surgeon in the operating room (OR) is a key element in developing residents' autonomy. The purpose of this study is to explore factors that affect attending surgeons' decision making regarding OR guidance provided to the resident. We used video-stimulated recall interviews (VSRI) throughout this 2-phase study. In Phase 1, 3 attending surgeons were invited to review separately 30 to 45 minute video segments of their prerecorded surgical operations to explore factors that influenced their OR guidance decision making. In Phase 2, 3 attending surgeons were observed and documented in the OR (4 operations, 341min). Each operating surgeon reviewed their videotaped surgical performance within 5 days of the operation to reflect on factors that affected their decision making during the targeted guidance events. All VSRI were recorded. Thematic analysis and manual coding were used to synthesize and analyze data from VSRI transcripts, OR observation documents, and field notes. A total of 255 minutes of VSRI involving 6 surgeons and 7 surgical operations from 5 different procedures were conducted. A total of 13 guidance decision-making influence factors from 4 categories were identified (Cohen's κ = 0.674): Setting (case schedule and patient morbidity), content (procedure attributes and case progress), resident (current competency level, trustworthiness, self-confidence, and personal traits), and attending surgeon (level of experience, level of comfort, preferred surgical technique, OR training philosophy, and responsibility as surgeon). A total of 5 factors (case schedule, patient morbidity, procedure attributes, resident current competency level, and trustworthiness) influenced attending surgeons' pre-OR guidance plans. "OR training philosophy" and "responsibility as surgeon" were anchor factors that affected attending surgeons' OR guidance decision-making patterns. Surgeons' OR guidance decision making is a dynamic process

To assess the perceived value of medical school student surgical society membership and its effect on determining future career aspirations. Cross-sectional survey. Three UK medical school student surgical societies. Undergraduate and postgraduate students. Of 119 students, 60 (50.4%) completed the survey. Of the respondents, 62.3% indicated that the surgical society had increased their awareness and knowledge about the different surgical specialties. Of the respondents who had decided on a career in surgery before joining the society, 67.6% stated that participating in society events had better prepared them for the career. Plastic surgery (13.3%), general surgery (11.7%), and neurosurgery (11.7%) were the 3 most popular specialties for future careers. Surgical skills workshops (21.9%), conferences (21.1%), and careers talks (16.4%) were chosen by students as the most useful career-guiding events organized by surgical societies.

This study attempts to assess the association between surgeon personality factors (measured by the Myers-Briggs Type Indicator personality inventory (MBTI(®))) and risk tolerance (measured by the Revised Physicians' Reactions to Uncertainty (PRU) and Physician Risk Attitude (PRA) scales). Instrument assessing surgeon personality profile (MBTI) and 2 questionnaires measuring surgeon risk tolerance and risk aversion (PRU and PRA). Saint Raphael campus of Yale New Haven Hospital in New Haven, Connecticut. Twenty categorical surgery residents and 7 surgical core faculty members. The following findings suggest there might be a relationship between surgeon personality factors and risk tolerance. In certain areas of risk assessment, it appears that surgeons with personality factors E (Extravert), T (Thinking), and P (Perception) demonstrated higher tolerance for risk. Conversely, as MBTI(®) dichotomies are complementary, surgeons with personality factors I (Introvert), F (Feeling), and J (Judgment) suggest risk aversion on these same measures. These findings are supported by at least 2 studies outside medicine demonstrating that personality factors E, N, T, and P are associated with risk taking. This preliminary research project represents an initial step in exploring what may be considered a fundamental component in a "successful" surgical personality. © 2013 Association of Program Directors in Surgery.

Full Text Available Background Guidelines and Class 1 evidence are strong factors that help guide surgeons’ decision-making, but dilemmas exist in selecting the best surgical option, usually without the benefit of guidelines or Class 1 evidence. A few studies have discussed the variability of surgical treatment options that are currently available, but no study has examined surgeons’ views on the influential factors that encourage them to choose one surgical treatment over another. This study examines the influential factors and the thought process that encourage surgeons to make these decisions in such circumstances. Methods Semi-structured face-to-face interviews were conducted with 32 senior consultant surgeons, surgical fellows, and senior surgical residents at the University of Toronto teaching hospitals. An e-mail was sent out for volunteers, and interviews were audio-recorded, transcribed verbatim, and subjected to thematic analysis using open and axial coding. Results Broadly speaking there are five groups of factors affecting surgeons’ decision-making: medical condition, information, institutional, patient, and surgeon factors. When information factors such as guidelines and Class 1 evidence are lacking, the other four groups of factors—medical condition, institutional, patient, and surgeon factors (the last-mentioned likely being the most powerful—play a significant role in guiding surgical decision-making. Conclusions This study is the first qualitative study on surgeons’ perspectives on the influential factors that help them choose one surgical treatment option over another for their patients.

Training in medicine must move to an outcome-based approach. A proficiency-based progression outcome approach to training relies on a quantitative estimation of experienced operator performance. We aimed to develop a method for dealing with atypical expert performances in the quantitative definition of surgical proficiency. In study one, 100 experienced laparoscopic surgeons' performances on virtual reality and box-trainer simulators were assessed for two similar laparoscopic tasks. In study two, 15 experienced surgeons and 16 trainee colorectal surgeons performed one simulated hand-assisted laparoscopic colorectal procedure. Performance scores of experienced surgeons in both studies were standardized (i.e. Z-scores) using the mean and standard deviations (SDs). Performances >1.96 SDs from the mean were excluded in proficiency definitions. In study one, 1-5% of surgeons' performances were excluded having performed significantly below their colleagues. Excluded surgeons made significantly fewer correct incisions (mean = 7 (SD = 2) versus 19.42 (SD = 4.6), P 4 SDs for time to complete the procedure and >6 SDs for path length. After their exclusions, experienced surgeons' performances were significantly better than trainees for path length: P = 0.031 and for time: P = 0.002. Objectively assessed atypical expert performances were few. Z-score standardization identified them and produced a more robust quantitative definition of proficiency. © 2018 Royal Australasian College of Surgeons.

The importance of effective team leadership for achieving surgical excellence is widely accepted, but we understand less about the behaviors that achieve this goal. We studied cardiac surgical teams to identify leadership behaviors that best support surgical teamwork. We observed, surveyed, and interviewed cardiac surgical teams, including 7 surgeons and 116 team members, from September 2013 to April 2015. We documented 1,926 surgeon/team member interactions during 22 cases, coded them by behavior type and valence (ie, positive/negative/neutral), and characterized them by leadership function (conductor, elucidator, delegator, engagement facilitator, tone setter, being human, and safe space maker) to create a novel framework of surgical leadership derived from direct observation. We surveyed nonsurgeon team members about their perceptions of individual surgeon's leadership effectiveness on a 7-point Likert scale and correlated survey measures with individual surgeon profiles created by calculating percentage of behavior types, leader functions, and valence. Surgeon leadership was rated by nonsurgeons from 4.2 to 6.2 (mean, 5.4). Among the 33 types of behaviors observed, most interactions constituted elucidating (24%) and tone setting (20%). Overall, 66% of interactions (range, 43%-84%) were positive and 11% (range, 1%-45%) were negative. The percentage of positive and negative behaviors correlated strongly (r = 0.85 for positive and r = 0.75 for negative, p leadership. Facilitating engagement related most positively (r = 0.80; p = 0.03), and negative forms of elucidating, ie, criticism, related most negatively (r = -0.81; p = 0.03). We identified 7 surgeon leadership functions and related behaviors that impact perceptions of leadership. These observations suggest actionable opportunities to improve team leadership behavior.

The incidence of surgical site infections (SSI) is considered increasingly to be an indicator of quality of care. We conducted a study in which daily inspection of the surgical incision was performed by an independent, trained team to monitor the incidence of SSI using U.S. Centers for Disease Control and Prevention (CDC) definitions, as a gold-standard measure of care. In the department of surgery, two registration systems for SSI were used routinely by the surgeon: An electronic and a plenary tracking system. The results of the independent team were compared with the outcomes provided by two registration systems for SSI, so as to evaluate the reliability of these systems as a possible alternative for indicating quality of care. The study was an incidence study conducted from May 2007 to January 2009 that included 1,000 adult patients scheduled to undergo open abdominal surgery in an academic teaching hospital. Surgical incisions were inspected daily to check for SSI according to definitions of health care-associated infections established by the CDC. Follow-up after discharge was done at the outpatient clinic of the hospital by telephone or letter in combination with patient diaries and reviews of patient charts, discharge letters, electronic files, and reported complications. Univariate and multivariable analyses were done to identify putative risk factors for missing registrations. Of the 1,000 patients in the study, 33 were not evaluated. Surgical site infections were diagnosed in 26.8% of the 967 remaining patients, of which 18.0% were superficial incisional infections, 5.4% were deep incisional infections, and 3.4% were organ/space infections. More than 60% of SSIs were unreported in either of the department's two tracking systems for such infections. For these two systems, independent major risk factors for missing registrations were (1) the lack of occurrence of an SSI, (2) transplantation surgery, and (3) admission to non-surgical departments. Most SSIs

The effects of surgeons' leadership on team performance are not well understood. The purpose of this study was to examine the simultaneous effects of transformational, passive, abusive supervision and over-controlling leadership behaviors by surgeons on surgical team performance. Trained observers attended 150 randomly selected operations at a tertiary care teaching hospital. Observers recorded instances of the four leadership behaviors enacted by the surgeon. Postoperatively, team members completed validated questionnaires rating team cohesion and collective efficacy. Multiple regression analyses were computed. Data were analyzed using the complex modeling function in MPlus. Surgeons' abusive supervision was negatively associated with psychological safety (unstandardized B = -0.352, p leadership (unstandardized B = -0.230, p leadership behaviors on intraoperative team performance. Significant effects only surfaced for negative leadership behaviors; transformational leadership did not positively influence team performance. Copyright © 2017 Elsevier Inc. All rights reserved.

The purpose of this study was to evaluate whether subspecialty training of the initial treating surgeon affects visual acuity and surgical outcomes in patients with open globe injuries. This study is a single-institution, retrospective case series. The charts of adult patients with open globe injuries requiring surgical repair at the Wilmer Eye Institute between July 1, 2007 and July 1, 2012 were retrospectively reviewed. Clinical findings at presentation were recorded, and details of initial repair and follow-up surgeries were analyzed. Differences in visual acuity and surgical outcomes were compared based on subspecialty training of the initial surgeon. The charts of 282 adult patients were analyzed, and 193 eyes had at least 6 months of follow-up for analysis. Eighty-six eyes (44.6%) required follow-up surgery within the first year, and 39 eyes (20.2%) were enucleated. Eyes initially treated by a vitreoretinal (VR) surgeon were 2.3 times (P=0.003) more likely to improve by one Ocular Trauma Score (OTS) visual acuity category and 1.9 times (P=0.027) more likely to have at least one more follow-up surgery at 6 months compared to eyes treated by non-VR surgeons. Patients with more anterior injuries treated by a VR surgeon were more likely to improve by one OTS visual acuity category compared to those treated by non-VR surgeons (P=0.004 and 0.016 for Zones I and II, respectively). There was no difference in visual acuity outcomes for eyes with posterior injuries (P=0.515 for Zone III). Eyes initially treated by a VR surgeon are more likely to improve by one OTS visual acuity category than those initially treated by a non-VR surgeon. However, patients initially treated by a VR surgeon also undergo more follow-up surgical rehabilitation, and improvement in visual acuity is more likely for anterior (Zone I and II injuries) than posterior (Zone III) injuries.

Accurate and appropriate assessment of surgical trainees requires clear determination of the skills needed for surgical competence. This study was designed to identify those skills, rank them in order of importance and translate them into behavioural terms. A Delphi technique, using anonymous postal questionnaires, was used. All consultant surgeons in South-East Scotland were asked to identify the skills they expected of surgical trainees. Skills identified were then returned to all consultants for weighting. Differences among specialties in the importance of each item were identified using analysis of variance. The qualities identified fell into five domains: technical skills, clinical skills, interaction with patients and relatives, teamwork, and application of knowledge. Consultants from all specialties gave high weightings to the generic domains of clinical skills, teamwork, and interaction with patients and relatives. This study has identified the skills considered necessary by consultant surgeons in Scotland for a successful surgical career. Contrary to expectation, consultant surgeons value many generic skills more highly than technical skills, indicating that they value well rounded doctors, not just those with technical ability. The characteristics identified are being used to develop an assessment tool for use on basic surgical trainees.

Implant position is a key determinant of esthetic and functional success. Achieving the goal of ideal implant position may be affected by case selection, prosthodontically driven treatment planning, site preparation, surgeon's experience and use of a surgical guide. The combined effect of surgical guide design, surgeon's experience, and size of the edentulous area on the accuracy of implant placement was evaluated in a simulated clinical setting. Twenty-one volunteers were recruited to participate in the study. They were divided evenly into 3 groups (novice, intermediate, and experienced). Each surgeon placed implants in single and double sites using 4 different surgical guide designs (no guide, tube, channel, and guided) and written instructions describing the ideal implant positions. A definitive typodont was constructed that had 3 implants in prosthetically determined ideal positions of single and double sites. The position and angulation of implants placed by the surgeons in the duplicate typodonts was measured using a computerized coordinate measuring machine and compared to the definitive typodont. The mean absolute positional error for all guides was 0.273, 0.340, 0.197 mm in mesial-distal, buccal-lingual, vertical positions, respectively, with an overall range of 0.00 to 1.81 mm. The mean absolute angle error for all guides was 1.61° and 2.39° in the mesial-distal and buccal-lingual angulations, respectively, with an overall range of 0.01° to 9.7°. Surgical guide design had a statistically significant effect on the accuracy of implant placement regardless of the surgeon's experience level. Experienced surgeons had significantly less error in buccal-lingual angulation. The size of the edentulous sites was found to affect both implant angle and position significantly. The magnitude of error in position and angulation caused by surgical guide design, surgeon's experience, and site size reported in this study are possibly not large enough to be clinically

Benign thyroid disorders are among the most common diseases in Germany, affecting around 15 million people and leading to more than 100,000 thyroid surgeries per year. Since the first German guidelines for the surgical treatment of benign goiter were published in 1998, abundant new information has become available, significantly shifting surgical strategy towards more radical interventions. Additionally, minimally invasive techniques have been developed and gained wide usage. These circumstances demanded a revision of the guidelines. Based on a review of relevant recent guidelines from other groups and additional literature, unpublished data, and clinical experience, the German Association of Endocrine Surgeons formulated new recommendations on the surgical treatment of benign thyroid diseases. These guidelines were developed through a formal expert consensus process and in collaboration with the German societies of Nuclear Medicine, Endocrinology, Pathology, and Phoniatrics & Pedaudiology as well as two patient organizations. Consensus was achieved through several moderated conferences of surgical experts and representatives of the collaborating medical societies and patient organizations. The revised guidelines for the surgical treatment of benign thyroid diseases include recommendations regarding the preoperative assessment necessary to determine when surgery is indicated. Recommendations regarding the extent of resection, surgical techniques, and perioperative management are also given in order to optimize patient outcomes. Evidence-based recommendations for the surgical treatment of benign thyroid diseases have been created to aid the surgeon and to support optimal patient care, based on current knowledge. These recommendations comply with the Association of the Scientific Medical Societies in Germany requirements for S2k guidelines.

Although surgical smoke contains potentially hazardous substances, such as cellular material, blood fragments, microorganisms, toxic gases and vapors, many operating rooms (ORs) do not provide protection from exposure to it. This article reviews the hazards of surgical smoke and the means of protecting OR personnel. Our objectives are to promote surgeons' acceptance to adopt measures to minimize the hazards. Depending on its components, surgical smoke can increase the risk of acute and chronic pulmonary conditions, cause acute headaches; irritation and soreness of the eyes, nose and throat; dermatitis and colic. Transmission of infectious disease may occur if bacterial or viral fragments present in the smoke are inhaled. The presence of carcinogens in surgical smoke and their mutagenic effects are also of concern. This review summarizes previously published reports and data regarding the toxic components of surgical smoke, the possible adverse effects on the health of operating room personnel and measures that can be used to minimize exposure to prevent respiratory problems. To reduce the hazards, surgical smoke should be removed by an evacuation system. Surgeons should assess the potential dangers of surgical smoke and encourage the use of evacuation devices to minimize potential health hazards to both themselves and other OR personnel.

Minimally invasive surgery (MIS) offers cosmetic benefits to patients; however, surgeons often experience pain during MIS. We administered an ergonomic questionnaire to 176 Korean laparoscopic gynecological surgeons to determine potential sources of pain during surgery. Logistic regression analysis was used to identify factors that had a significant impact on gynecological surgeons' pain. Operating table height at the beginning of surgery and during the operation were significantly associated with neck and shoulder discomfort (P ergonomic solutions to reduce gynecological laparoscopic surgeons' pain. Based on our results, we propose the use of an ergonomic surgical step stool to reduce physical pain related to performing laparoscopic operations.

Surgical tracheostomy is a commonly provided service by surgical teams for patients in intensive care where percutaneous dilatational tracheostomy is contraindicated. A number of factors may interfere with its provision on shared emergency operating lists, potentially prolonging the stay in intensive care. We undertook a two-part project to examine the factors that might delay provision of surgical tracheostomy in the intensive care unit. The first part was a prospective audit of practice within the University Hospital Coventry. This was followed by a telephone survey of oral and maxillofacial surgery units throughout the UK. In the intensive care unit at University Hospital Coventry, of 39 referrals, 21 (53.8%) were delayed beyond 24 hours. There was a mean (standard deviation) time to delay of 2.2 days (0.9 days) and the most common cause of delay was surgeon decision, accounting for 13 (61.9%) delays. From a telephone survey of 140 units nationwide, 40 (28.4%) were regularly involved in the provision of surgical tracheostomies for intensive care and 17 (42.5%) experienced delays beyond 24 hours, owing to a combination of theatre availability (76.5%) and surgeon availability (47.1%). There is case for having a dedicated tracheostomy team and provisional theatre slot to optimise patient outcomes and reduce delays. We aim to implement such a move within our unit and audit the outcomes prospectively following this change.

The aim of this experimental study was to identify relevant surgical parameters influencing the mesiodistal angular deviation of dental implants. Pilot drillings of 2 mm diameter were performed in bovine ribs with a parallelometer. The subsequent preparation of the implant socket was performed freehand. Utilizing six different implant systems, at least 80 drillings per system of different diameters were performed. The pilot drillings were marked with 2 mm steel pins and cephalometric radiographs were taken. The mesiodistal angle between the longitudinal implant axis and the marked pilot drillings was measured and evaluated by a blinded investigator. To evaluate the influence of the surgeons' experience, their drillings were compared with those of a group of unexperienced surgeons. Additionally, the influence of drilling speed and size of bur steps on drilling accuracy were evaluated. The difference between the lowest value of 0.91 degrees of mesiodistal angular deviation found for 3i implants and the highest of 1.36 degrees for Ankylos implants was of low statistical significance (P=0.065). Drillings of experienced surgeons showed less deviation compared with those of a beginners group (P<0.0001). Higher deviations were measured when a bur size was skipped. Drillings performed at high speed showed significantly higher deviations than those with fewer rewinds per minute. In order to achieve precise implant angulation, all bur diameters available should be used. Utilizing low drilling speeds results in less mesiodistal deviation. The surgeon's experience seems to be the most relevant factor in precise implant placement.

BACKGROUND: Surgical checklists has been shown to improve patient safety and teamwork in the operating theatre. However, despite the known benefits of the use of checklists in surgery, in some cases the practical implementation has been found to be less than universal. A questionnaire methodology was used to quantitatively evaluate the attitudes of theatre staff towards a modified version of the World Health Organisation (WHO) surgical checklist with relation to: beliefs about levels of compliance and support, impact on patient safety and teamwork, and barriers to the use of the checklist. METHODS: Using the theory of planned behaviour as a framework, 14 semi-structured interviews were conducted with theatre personnel regarding their attitudes towards, and levels of compliance with, a checklist. Based upon the interviews, a 27-item questionnaire was developed and distribute to all theatre personnel in an Irish hospital. RESULTS: Responses were obtained from 107 theatre staff (42.6% response rate). Particularly for nurses, the overall attitudes towards the effect of the checklist on safety and teamworking were positive. However, there was a lack of rigour with which the checklist was being applied. Nurses were significantly more sensitive to the barriers to the use of the checklist than anaesthetists or surgeons. Moreover, anaesthetists were not as positively disposed to the surgical checklist as surgeons and nurse. This finding was attributed to the tendency for the checklist to be completed during a period of high workload for the anaesthetists, resulting in a lack of engagement with the process. CONCLUSION: In order to improve the rigour with which the surgical checklist is applied, there is a need for: the involvement of all members of the theatre team in the checklist process, demonstrated support for the checklist from senior personnel, on-going education and training, and barriers to the implementation of the checklist to be addressed.
In the first half of the twentieth century, the training of American surgeons changed from an idiosyncratic, often isolated venture to a standardized, regulated, and mandated regimen in the form of the surgical residency. Over the three critical decades between 1930 and 1960, these residencies developed from an extraordinary, unique opportunity for a few leading practitioners to a widespread, uniform requirement. This article explores the transformation of surgical education in the United States, focusing on the standardization and dissemination of residencies during this key period. Utilizing the archives of professional organizations, it shows how surgical societies initiated and forced reform in the 1930s. It demonstrates the seminal and early role taken by the federal government in the expansion of surgical residencies through incentivized policies and, especially, the growth of the Veterans Administration health system after World War II. Finally, an examination of intra-professional debates over this process illustrates both the deeper struggles to control the nature of surgical training and the importance of residency education in defining the midcentury American surgeon. © The Author(s) 2018.

There is a wide variability in the management of acute cholecystitis. A survey among the members of the Spanish Association of Surgeons (AEC) analyzed the preferences of Spanish surgeons for its surgical management. The majority of the 771 responders didn't declare any subspecialty (41.6%), 21% were HPB surgeons, followed by colorectal and upper-GI specialities. Early cholecystectomy during the first admission is the preferred method of management of 92.3% of surgeons, but only 42.7% succeed in adopting this practice. The most frequent reasons for changing their preferred practice were: Patients not fit for surgery (43.6%) and lack of availability of emergency operating room (35.2%). A total of 88.9% perform surgery laparoscopically. The majority of AEC surgeons advise index admission cholecystectomy for acute cholecystitis, although only half of them succeed in its actual implementation. There is room for improvement in the management of acute cholecystitis in Spanish hospitals. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

Questionnaire survey. To explore spine surgeons' attitudes toward the involvement of nonphysician clinicians (NPCs) to screen patients with low back or low back-related leg pain referred for surgical assessment. Although the utilization of physician assistants is common in several healthcare systems, the attitude of spine surgeons toward the independent assessment of patients by NPCs remains uncertain. We administered a 28-item survey to all 101 surgeon members of the Canadian Spine Society, which inquired about demographic variables, patient screening efficiency, typical wait times for both assessment and surgery, important components of low back-related complaints history and examination, indicators for assessment by a surgeon, and attitudes toward the use of NPCs to screen patients with low back and leg pain referred for elective surgical assessment. Eighty-five spine surgeons completed our survey, for a response rate of 84.1%. Most respondents (77.6%) were interested in working with an NPC to screen patients with low back-related complaints referred for elective surgical assessment. Perception of suboptimal wait time for consultation and poor screening efficiency for surgical candidates were associated with greater surgeon interest in an NPC model of care. We achieved majority consensus regarding the core components for a low back-related complaints history and examination, and findings that would support surgical assessment. A majority of respondents (75.3%) agreed that they would be comfortable not assessing patients with low back-related complaints referred to their practice if indications for surgery were ruled out by an NPC. The majority of Canadian spine surgeons were open to an NPC model of care to assess and triage nonurgent or emergent low back-related complaints. Clinical trials to establish the effectiveness and acceptance of an NPC model of care by all stakeholders are urgently needed.

Objective: To assess the impact of the 80-hour resident workweek restrictions on surgical residents and attending surgeons. Summary Background Data: The ACGME mandated resident duty hour restrictions have required a major workforce restructuring. The impact of these changes needs to be critically evaluated for both the resident and attending surgeons, specifically with regards to the impact on motivation, job satisfaction, the quality of surgeon training, the quality of the surgeon's life, and the quality of patient care. Methods: Four prospective studies were performed at a single academic surgical program with data collected both before the necessary workforce restructuring and 1 year after, including: 1) time cards to assess changes in components of daily activity; 2) Web-based surveys using validated instruments to assess burnout and motivation to work; 3) structured, taped, one-on-one interviews with an external PhD investigator; and 4) statistical analyses of objective, quantitative data. Results: After the work-hour changes, surgical residents have decreased “burnout” scores, with significantly less “emotional exhaustion” (Maslach Burnout Inventory: 29.1 “high” vs. 23.1 “medium,” P = 0.02). Residents have better quality of life both in and out of the hospital. They felt they got more sleep, have a lighter workload, and have increased motivation to work (Herzberg Motivation Dimensions). We found no measurable, statistically significant difference in the quality of patient care (NSQIP data). Resident training and education objectively were not statistically diminished (ACGME case logs, ABSITE scores). Attending surgeons perceived that their quality of their life inside and outside of the hospital was “somewhat worse” because of the work-hour changes, as they had anticipated. Many concerns were identified with regards to the professional development of future surgeons, including a change toward a shift-worker mentality that is not patient

There is a general consensus by intensivists and nonsurgical providers that surgeons hesitate to withdraw life-sustaining therapy on their operative patients despite a patient's or surrogate's request to do so. The objective of this study was to examine the culture and practice of surgeons to assess attitudes and concerns regarding advance directives for their patients who have high-risk surgical procedures. A qualitative investigation using one-on-one, in-person interviews with open-ended questions about the use of advance directives during perioperative planning. Consensus coding was performed using a grounded theory approach. Data accrual continued until theoretical saturation was achieved. Modeling identified themes and trends, ensuring maximal fit and faithful data representation. Surgical practices in Madison and Milwaukee, WI. Physicians involved in the performance of high-risk surgical procedures. None. We describe the concept of surgical "buy-in," a complex process by which surgeons negotiate with patients a commitment to postoperative care before undertaking high-risk surgical procedures. Surgeons describe seeking a commitment from the patient to abide by prescribed postoperative care, "This is a package deal, this is what this operation entails," or a specific number of postoperative days, "I will contract with them and say, 'look, if we are going to do this, I am going to need 30 days to get you through this operation.'" "Buy-in" is grounded in a surgeon's strong sense of responsibility for surgical outcomes and can lead to surgeon unwillingness to operate or surgeon reticence to withdraw life-sustaining therapy postoperatively. If negotiations regarding life-sustaining interventions result in treatment limitation, a surgeon may shift responsibility for unanticipated outcomes to the patient. A complicated relationship exists between the surgeon and patient that begins in the preoperative setting. It reflects a bidirectional contract that is assumed by

Although previous studies have demonstrated the needs for a spatial cognitive ability that can give an accurate understanding of the position, orientation, and size and form of the objects in endoscopic surgery, there has been no study on the relationship between the skills of robot-assisted surgery and spatial cognitive ability. To assess the effect of spatial cognitive ability on gain in robot-assisted surgical skills of urological surgeons. The robot-assisted surgery skills of 24 urological surgeons who had no previous experience with the Mimic dV-Trainer (MdVT) and had not been the main surgeon in robot-assisted surgery and 20 volunteer medical students who had no previous experience of the MdVT were assessed by using a program consisting of 4 kinds of tasks. Their performances were recorded using a built-in scoring algorithm. Their spatial cognitive abilities were also assessed using a mental rotation test. Although there was a significant correlation between the spatial cognitive ability and a score of 2 for the more difficult tasks for student groups using the MdVT, there was no significant correlation between them for all tasks for groups of urological surgeons. The results of the present study indicate that differences in spatial cognitive ability in urological surgeons have no effect on the gain in fundamental robot-assisted surgery skills whereas there was a significant correlation between the spatial cognitive ability and fundamental robot-assisted surgical skills in the volunteers.

In 1904, William Halsted introduced the present model of surgical residency program which has been adopted worldwide. In some developing countries, where surgical residency training programs are new, some colleges have introduced innovations to the Halsted's original concept of surgical residency training. These include 1) primary examination, 2) rural surgical posting, and 3) submission of dissertation for final certification. Our information was gathered from the publications on West African College of Surgeons' (WACS) curriculum of the medical schools, faculty papers of medical schools, and findings from committees of medical schools. Verbal information was also gathered via interviews from members of the WACS. Additionally, our personal experience as members and examiners of the college are included herein. We then noted the differences between surgical residency training programs in the developed countries and that of developing countries. The innovations introduced into the residency training programs in the developing countries are mainly due to the emphasis placed on paper qualifications and degrees instead of performance. We conclude that the innovations introduced into surgical residency training programs in developing countries are the result of the misconception of what surgical residency training programs entail.

Full Text Available Several studies have shown that wound infection (surgical site infection [ ssi ] rates fall when surgeons are provided with data on their performance. Since 1987, the authors have been performing concurrent surveillance of surgical patients and confidentially reporting surgeon-specific ssi rates to individual surgeons and their clinical directors, and providing surgeons with the mean rates of their peers. The program has been gradually refined and expanded. Data are now collected on wound infection risk and report risk adjusted rates compared with the mean for hospitals in the United States National Nosocomial Infections Surveillance (nnis data bank. Since inception through to December 1993, ssi rates have fallen 68% in clean contaminated general surgery cases (relative risk [rr] 0.36, 95% ci 0.2 to 0.6, P=0.0001, 64% in clean plastic surgery cases (rr 0.35, 95% ci 0.06 to 1.8, 72% in caesarean section cases (rr 0.23, 95% ci 0.03 to 1.96 and 42% in clean cardiovascular surgery cases (rr 0.59, 95% ci 0.34 to 1.0. In clean orthopedic surgery the ssi rate remained stable from 1987 through 1992. In 1993 a marked increase was experienced. Reasons for this are being explored. Overall there was a 32% decrease in ssi rate between the index year and 1993 or, in percentage terms, 2.8% to 1.9% (rr 0.65, 95% ci 0.51 to 0.86, P=0.002. ssi surveillance should become standard in Canadian hospitals interested in improving the quality of surgical care and reducing the clinical impact and cost associated with nosocomial infection.

The aim of this study was to evaluate whether inexpensive 3D models can be suitable to train surgical skills to dental students or oral and maxillofacial surgery residents. Furthermore, we wanted to know which of the most common filament materials, acrylonitrile butadiene styrene (ABS) or polylactic acid (PLA), can better simulate human bone according to surgeons' subjective perceptions. Upper and lower jaw models were produced with common 3D desktop printers, ABS and PLA filament and silicon rubber for soft tissue simulation. Those models were given to 10 blinded, experienced maxillofacial surgeons to perform sinus lift and wisdom teeth extraction. Evaluation was made using a questionnaire. Because of slightly different density and filament prices, each silicon-covered model costs between 1.40-1.60 USD (ABS) and 1.80-2.00 USD (PLA) based on 2017 material costs. Ten experienced raters took part in the study. All raters deemed the models suitable for surgical education. No significant differences between ABS and PLA were found, with both having distinct advantages. The study demonstrated that 3D printing with inexpensive printing filaments is a promising method for training oral and maxillofacial surgery residents or dental students in selected surgical procedures. With a simple and cost-efficient manufacturing process, models of actual patient cases can be produced on a small scale, simulating many kinds of surgical procedures. © 2018 John Wiley & Sons A/S.

Full Text Available Introduction: The last two decades have seen the adoption of simulation-based surgical education in various disciplines. The current study’s goal was to perform a needs assessment using the results to inform future curricular planning and needs of surgeons and learners. Methods: A survey was distributed to 26 surgeon educators and interviews were conducted with 8 of these surgeons. Analysis of survey results included reliability and descriptive statistics. Interviews were analyzed for thematic content with a constant comparison technique, developing coding and categorization of themes. Results: The survey response rate was 81%. The inter-item reliability, according to Cronbach’s alpha was 0.81 with strongest agreement for statements related to learning new skills, training new residents and the positive impact on patient safety and learning. There was less strong agreement for maintenance of skills, improving team functioning and reducing teaching in the operating room. Interview results confirmed those themes from the survey and highlighted inconsistencies for identified perceived barriers and a focus on acquisition of skills only. Interview responses specified concerns with integrating simulation into existing curricula and the need for more evaluation as a robust educational strategy. Conclusion: The findings were summarized in four themes: 1 use of simulation, 2 integration into curriculum, 3 leadership, and 4 understanding gaps in simulation use. This study exemplifies a mixed-methods approach to planning a surgical simulation program through a general needs assessment.

Robotic surgery has witnessed a huge expansion. Robotic simulators have proved to be of major interest in training. Some authors have suggested that prior experience in micro-surgery could improve robotic surgery training. To test micro-surgery as a new approach in training, we proposed a prospective study comparing the surgical performance of micro-surgeons with that of general surgeons on a robotic simulator. 49 surgeons were enrolled; 11 in the micro-surgery group (MSG); 38 n the control group (CG). Performance was evaluated based on five dV-Trainer® exercises. MSG achieved better results for all exercises including exercises requiring visual evaluation of force feed-back, economy of motion, instrument force and position. These results show that experience in micro-surgery could significantly improve surgeons' abilities and their performance in robotic training. So, as micro-surgery practice is relatively cheap, it could be easily included in basic robotic surgery training. Copyright © 2013 John Wiley & Sons, Ltd.

We showed in a companion paper that the prevalence of burnout among surgical oncologists at a comprehensive cancer center was 42% and psychiatric morbidity 27%, and high quality of life (QOL) was absent for 54% of surgeons. Here we examine modifiable workplace factors and other stressors associated with burnout, psychiatric morbidity, and low QOL, together with interest in interventions to reduce distress and improve wellness. Study-specific questions important for morale, QOL, and stressors associated with burnout were included in an anonymous Internet-based survey distributed to the surgical faculty at Memorial Sloan-Kettering Cancer Center. Among the 72 surgeons who responded (response rate of 73%), surgeons identified high stress from medical lawsuits, pressure to succeed in research, financial worries, negative attitudes to gender, and ability to cope with patients' suffering and death. Workplace features requiring greatest change were the reimbursement system, administrative support, and schedule. Work-life balance and relationship issues with spouse or partner caused high stress. Strongest correlations with distress were a desire to change communication with patients and the tension between the time devoted to work versus time available to be with family. Surgeons' preferences for interventions favored a fitness program, nutrition consultation, and increased socialization with colleagues, with less interest in interventions conventionally used to address psychological distress. Several opportunities to intervene at the organizational level permit efforts to reduce burnout and improve QOL.

The burden of complex orthopedic trauma in low- and middle-income countries (LMICs) is exacerbated by soft-tissue injuries, which can often lead to amputations. This study's purpose was to create and evaluate the Surgical Management and Reconstruction Training (SMART) course to help orthopedic surgeons from LMICs manage soft-tissue defects and reduce the rate of amputations. In this prospective observational study, orthopedic surgeons from LMICs were recruited to attend a 2-day SMART course taught by plastic surgery faculty in San Francisco. Before the course, participants were asked to assess the burden of soft-tissue injury and amputation encountered at their respective sites of practice. A survey was then given immediately and 1-year postcourse to evaluate the quality of instructional materials and the course's effect in reducing the burden of amputation, respectively. Fifty-one practicing orthopedic surgeons from 25 countries attended the course. No participant reported previously attempting a flap reconstruction procedure to treat a soft-tissue defect. Before the course, participants cumulatively reported 580-970 amputations performed annually as a result of soft-tissue defects. Immediately after the course, participants rated the quality and effectiveness of training materials to be a mean of ≥4.4 on a Likert scale of 5 (Excellent) in all 14 instructional criteria. Of the 34 (66.7%) orthopedic surgeons who completed the 1-year postcourse survey, 34 (100%, P soft-tissue defects. Flap procedures prevented 116 patients from undergoing amputation; 554 (93.3%) of the cumulative 594 flaps performed by participants 1 year after the course were reported to be successful. Ninety-seven percent of course participants taught flap reconstruction techniques to colleagues or residents, and a self-reported estimate of 28 other surgeons undertook flap reconstruction as a result of information dissemination by 1 year postcourse. The SMART Course can give orthopedic surgeons

Acute care surgeons care for the entire breadth of the American adult population, including obese patients. As the population gets heavier, more patients will present to acute case surgeons with nonbariatric surgical emergencies. Do these surgeons need bariatric training to properly care for obese population? To evaluate our experience in obese population requiring acute surgery and compare outcomes based on surgeon expertise in bariatric surgery. Community teaching hospital, United States. Retrospective review of obese patients requiring acute surgical intervention. Surgeons were classified as bariatric surgeons (B, n = 2) versus nonbariatric surgeons (NB, n = 4). Demographic characteristics, co-morbidities, and outcomes based on surgeon training were compared. Two hundred three patients comprised the cohort. The mean body mass index was 37 ±6 kg/m 2 . The majority of procedures were laparoscopic (cholecystectomies n = 75, appendectomies n = 45). The remaining nonroutine laparoscopic cases were intestinal obstructions (n = 9), incarcerated hernias (n = 17), traumatic injuries (n = 48), and intestinal ischemia or perforation (n = 9). Bariatric surgeons performed 35% of cases, and risk profiles were similar between groups. Operative times were similar for cholecystectomies and appendectomies. Bariatric surgeons performed more nonroutine cases laparoscopically (7% B versus 2% NB, P = .001). Surgical site infections were low (2% B versus 4% NB, P = .4). Hospital length of stay was higher in the NB group at 9 ± 9 days versus 5 ± 4 days for B (P = .05). Mortality was 5%. Acute surgical procedures were performed in obese patients. Bariatric expertise favorably affected length of stay and the application of laparoscopy. Bariatric expertise may improve outcomes in nonbariatric emergencies, but further study is warranted.

Although the potential benefits of stereoscopic laparoscopy have been recognized for years, the technology has not been adopted because of poor operator tolerance. Passive polarizing projection systems, which have revolutionized three-dimensional (3D) cinema, are now being trialled in surgery. This study was designed to see whether this technology resulted in significant performance benefits for skilled laparoscopists. Four validated laparoscopic skills tasks, each with ten repetitions, were performed by 20 experienced laparoscopic surgeons, in both two-dimensional (2D) and 3D conditions. The primary outcome measure was the performance error rate; secondary outcome measures were time for task completion, 3D motion tracking (path length, motion smoothness and grasping frequency) and workload dimension ratings of the National Aeronautics and Space Administration (NASA) Task Load Index. Surgeons demonstrated a 62 per cent reduction in the median number of errors and a 35 per cent reduction in median performance time when using the passive polarizing 3D display compared with the 2D display. There was a significant 15 per cent reduction in median instrument path length, an enhancement of median motion smoothness, and a 15 per cent decrease in grasper frequency with the 3D display. Participants reported significant reductions in subjective workload dimension ratings of the NASA Task Load Index following use of the 3D displays. Passive polarizing 3D displays improved both the performance of experienced surgeons in a simulated setting and surgeon perception of the operative field. Although it has been argued that the experience of skilled laparoscopic surgeons compensates fully for the loss of stereopsis, this study indicates that this is not the case. Surgical relevance The potential benefits of stereoscopic laparoscopy have been known for years, but the technology has not been adopted because of poor operator tolerance. The first laparoscopic operation was carried out

To determine the rate of surgical site infection (SSI) after resection of an intracranial neoplasm using the American College of Surgeons National Surgical Quality Improvement Program data set and to identify potential risk factors associated with SSI. The National Surgical Quality Improvement Program Participant Use Data File was queried during the period 2006-2013 for patients who underwent a resection for an intracranial neoplasm. Multivariable logistic regression analysis was used to identify risk factors associated with SSI. Inclusion criteria were met by 12,021 patients. SSI occurred at a rate of 2.04%. SSI was significantly associated with increased rates of return to the operating room (56.1% vs. 4.0%, P 30 days (5.3% vs. 1.3%, P 4 hours (OR = 1.891, 95% CI = 1.298-2.756) were associated with an increased odds of SSI. Among cases with available chemotherapy data (n = 3504), recent chemotherapy (OR = 3.007, 95% CI = 1.460-6.196) was associated with an increased odds of SSI. This study identified patient risk factors that may assist clinical decision making regarding patient risk stratification, timing of surgery, and preoperative antibiotic prophylaxis for patients with an intracranial neoplasm undergoing craniotomy.

Clinical research increasingly acknowledges the existence of significant procedural variation in surgical practice. This study explored surgeons' perspectives regarding the influence of intersurgeon procedural variation on the teaching and learning of surgical residents. This qualitative study used a grounded theory-based analysis of observational and interview data. Observational data were collected in 3 tertiary care teaching hospitals in Ontario, Canada. Semistructured interviews explored potential procedural variations arising during the observations and prompts from an iteratively refined guide. Ongoing data analysis refined the theoretical framework and informed data collection strategies, as prescribed by the iterative nature of grounded theory research. Our sample included 99 hours of observation across 45 cases with 14 surgeons. Semistructured, audio-recorded interviews (n = 14) occurred immediately following observational periods. Surgeons endorsed the use of intersurgeon procedural variations to teach residents about adapting to the complexity of surgical practice and the norms of surgical culture. Surgeons suggested that residents' efforts to identify thresholds of principle and preference are crucial to professional development. Principles that emerged from the study included the following: (1) knowing what comes next, (2) choosing the right plane, (3) handling tissue appropriately, (4) recognizing the abnormal, and (5) making safe progress. Surgeons suggested that learning to follow these principles while maintaining key aspects of surgical culture, like autonomy and individuality, are important social processes in surgical education. Acknowledging intersurgeon variation has important implications for curriculum development and workplace-based assessment in surgical education. Adapting to intersurgeon procedural variations may foster versatility in surgical residents. However, the existence of procedural variations and their active use in surgeons

Aim The use of a minimally invasive approach to treat appendicitis has yet to be universally accepted. The objective of this study was to examine recent trends in Ireland in the surgical management of acute appendicitis. Method Data were obtained from the Irish Hospital In-Patient Enquiry system for patients discharged with a diagnosis of appendicitis between 1999 and 2007. An anonymous postal survey was sent to all general surgeons of consultant and registrar level in Ireland to assess current attitudes to the use of laparoscopic appendectomy. Results The use of laparoscopic appendectomy increased throughout the study and was the most common approach for appendectomy in 2007. Multivariate analysis revealed age under 50 years (OR = 1.51), female sex (OR = 2.84) and residence in high-density population areas (OR = 4.15) as predictive factors for undergoing laparoscopic appendectomy in the most recent year of the study. While 97% of surgeons reported current use of laparoscopy in patients with acute right iliac fossa pain, in most cases it was selective. Surgeons in university teaching hospitals (42 of 77; 55%) were more likely to report using laparoscopic appendectomy for all cases of appendicitis than those in regional (six of 23; 26%) or general (13 of 53; 25%) hospitals (P = 0.048). Conclusion This study has demonstrated a significant increase in laparoscopic appendectomy, yet a variety of patient and surgeon factors contribute to the choice of procedure. Differences in the perception of benefit of the laparoscopic approach amongst surgeons appears to be an important factor in determining the operative approach for appendectomy.

Introduction Although a fading tradition in some institutions, having clinicians teach anatomy by whole-body dissection provides a clinical context to undergraduate and postgraduate medical students, increasing their depth of learning. The reasons for a clinician’s motivation to teach may be articulated in accordance with self-determination theory (SDT). SDT proposes that for individuals to be intrinsically motivated, three key elements are needed: 1) autonomy, 2) competence, and 3) relatedness. Materials and methods Data were collected through semistructured interviews with eight surgeons who were supervisors/facilitators in the anatomy by whole-body dissection course for undergraduate students in the Bachelor of Medicine, Bachelor of Surgery program and postgraduate students in the Master of Surgery program at the University of Sydney. Qualitative analysis methods were used to code and categorize data into themes. Results Our study used SDT as a conceptual framework to explore surgeons’ motivation to supervise students in the anatomy by whole-body dissection courses. Elements that facilitated their desire to teach included satisfaction derived from teaching, a sense of achievement in providing students with a clinical context, a strong sense of community within the dissection courses, and a sense of duty to the medical/surgical profession and to patient welfare. Conclusion The surgeons’ motivation for teaching was largely related to their desire to contribute to the training of the next generation of doctors and surgeons, and ultimately to future patient welfare.

Flank position is extensively used in retroperitoneoscopic urological practice. Most surgeons follow the patients' position in open approaches. However, surgical ergonomics of the conventional position in the retroperitoneoscopic surgery is poor. We introduce a modified position and evaluated task performance and surgical ergonomics of both positions with simulated surgical tasks. Twenty-one novice surgeons were recruited to perform four tasks: bead transfer, ring transfer, continuous suturing, and cutting a circle. The conventional position was simulated by setting an endo-surgical simulator parallel to the long axis of a surgical desk. The modified position was simulated by rotating the simulator 30° with respect to the long axis of the desk. The outcome measurements include task performance measures, kinematic measures for body alignment, surface electromyography, relative loading between feet, and subjective ratings of fatigue. We observed significant improvements in both task performance and surgical ergonomics parameters under the modified position. For all four tasks, subjects finished tasks faster with higher accuracy (p ergonomics part: (1) The angle between the upper body and the head was decreased by 7.4 ± 1.7°; (2) The EMG amplitude collected from shoulders and left lumber was significantly lower (p ergonomics. With a simulated surgery, we demonstrated that our modified position could significantly improve task performance and surgical ergonomics. Further studies are still warranted to validate these benefits for both patients and surgeons.

A clear understanding of simulation-based curricula in use at American College of Surgeons Accredited Education Institutes (ACS-AEIs) is lacking. A 25-question online survey was sent to ACS-AEIs. The response rate approached 60%. The most frequent specialties to use the ACS-AEIs are general surgery and obstetrics/gynecology (94%). Residents are the main target population for programming/training (96%). Elements of the ACS/Association of Program Directors in Surgery Surgical Skills Curriculum are used by 77% of responding ACS-AEIs. Only 49% of ACS-AEIs implement the entire curriculum and 96% have independently developed their own surgical skills curricula. "Home-grown" simulators have been designed at 71% of ACS-AEIs. Feasibility (80%), evidence of effectiveness (67%), and cost (60%) were reasons for curriculum adoption. All programs use operative assessment tools for resident performance, and 53% use Messick's unitary framework of validity. Most programs (88%) have financial support from their academic institute. Majority of ACS-AEIs had trainees evaluate their faculty instructors (90%), and the main form of such faculty evaluation was postcourse surveys (97%). This study provides specific information regarding simulation-based curricula at ACS-AEIs. Copyright © 2016 Elsevier Inc. All rights reserved.

The aim of this study was to determine if direct in-person communication between an acute care surgical team and radiologists alters surgical decision making. Informed consent was waived for this institutional review board-exempt, HIPAA-compliant, prospective quality improvement study. From January 29, 2015 to December 10, 2015, semiweekly rounds lasting approximately 60 min were held between the on-call acute care surgery team (attending surgeon, chief resident, and residents) and one of three expert abdominal radiologists. A comprehensive imaging review was performed of recent and comparison examinations for cases selected by the surgeons in which medical and/or surgical decision making was pending. All reviewed examinations had available finalized reports known to the surgical team. RADPEER interradiologist concordance scores were assigned to all reviewed examinations. The impression and plan of the attending surgeon were recorded before and after each in-person review. One hundred patients were reviewed with 11 attending surgeons. The in-person meetings led to changes in surgeons' diagnostic impressions in 43% (43 of 100) and changes in medical and/or surgical planning in 43% (43 of 100; 20 acute changes, 23 nonacute changes, 19 changes in operative management) of cases. There were major discrepancies (RADPEER score ≥3) between the impression of the reviewing radiologist and the written report in 11% of cases (11 of 100). Targeted in-person collaboration between radiologists and acute care surgeons is associated with substantial and frequent changes in patient management, even when the original written report contains all necessary data. The primary mechanism seems to be promotion of a shared mental model that facilitates the exchange of complex information. Copyright © 2016 American College of Radiology. Published by Elsevier Inc.

Human factors (HF) study is mandatory to get air transport pilot licences. In aviation, crew resource management (CRM) and declaration of adverse events (feedback) result in improving of air safety. Air missions and surgical procedures have similarities. Bridging the gap is tempting, despite severe warnings against simplistic adaptation. Putting HF theory into surgical practice: how to? Educational principles derived from CRM improve professional attitudes of a team. We propose to translate concepts of CRM to clinical teams. CRM training applying in surgery could allow the work environment to be restructured to reduce human error. Feedback: in aviation, the Bureau of Flight Safety deals with investigations for air events. Pilots, air traffic controllers can anonymously declare nuisance, resulting in a feedback for the whole air force. Adverse events are analysed. Usually, multilevel problems are found, rather than the only responsibility of the last operator. Understanding the mechanisms of human failure finally improves safety. In surgery, CRM and feedback would probably be helpful. Anyway, it requires time; people have to change their mind. Nevertheless people such as fighter pilots, who were very unwilling at the beginning, now consider HF as a cornerstone for security. But it is difficult to estimate the extent of HF-related morbidity and mortality. We propose as a first step to consider CRM and feedback in surgical procedure. HF deals with the mechanisms of human errors and the ways to improve safety and probably improve the surgical team's efficacy.

Evaluation is a means for significant and rigorous improvement of the educational process. Therefore, competence evaluation should allow assessing the complex activity of medical care, as well as improving the training process. This is the case in the evaluation process of clinical-surgical competences. A cross-sectional study was designed to measure knowledge about the evaluation of clinical-surgical competences for the General Surgery residency program at the Faculty of Medicine, Universidad Autónoma de Chihuahua (UACH). A 55-item questionnaire divided into six sections was used (perception, planning, practice, function, instruments and strategies, and overall evaluation), with a six level Likert scale, performing a descriptive, correlation and comparative analysis, with a significance level of 0.001. In both groups perception of evaluation was considered as a further qualification. As regards tools, the best known was the written examination. As regards function, evaluation was considered as a further administrative requirement. In the correlation analysis, evaluation was perceived as qualification and was significantly associated with measurement, assessment and accreditation. In the comparative analysis between residents and staff surgeons, a significant difference was found as regards the perception of the evaluation as a measurement of knowledge (Student t test: p=0.04). The results provide information about the concept we have about the evaluation of clinical-surgical competences, considering it as a measure of learning achievement for a socially required certification. There is confusion as regards the perception of evaluation, its function, goals and scopes as benefit for those evaluated. Copyright © 2015 Academia Mexicana de Cirugía A.C.

Mexican cleft surgeons provide multidisciplinary comprehensive cleft lip and palate care to children in Mexico. Many Mexican cleft surgeons have extensive experience with foreign, visiting surgeons. The purpose of this study was to characterize Mexican cleft surgeons' domestic and volunteer practice and to learn more about Mexican cleft surgeons' experience with visiting surgeons. A cross-sectional validated e-mail survey tool was sent to Mexican cleft surgeons through 2 Mexican plastic surgery societies and the Asociación Mexicana de Labio y Paladar Hendido y Anomalías Craneofaciales, the national cleft palate society that includes plastic and maxillofacial surgeons who specialize in cleft surgery. We utilized validated survey methodology, including neutral fact-based questions and repeated e-mails to survey nonresponders to maximize validity of statistical data; response rate was 30.6% (n = 81). Mexican cleft surgeons performed, on average, 37.7 primary palate repairs per year with an overall complication rate of 2.5%; 34.6% (n = 28) of respondents had direct experience with patients operated on by visiting surgeons; 53.6% of these respondents performed corrective surgery because of complications from visiting surgeons. Respondents rated 48% of the functional outcomes of visiting surgeons as "acceptable," whereas 43% rated aesthetic outcomes of visiting surgeons as "poor"; 73.3% of respondents were never paid for the corrective surgeries they performed. Thirty-three percent of Mexican cleft surgeons believe that there is a role for educational collaboration with visiting surgeons. Mexican cleft surgeons have a high volume of primary cleft palate repairs in their domestic practice with good outcomes. Visiting surgeons may play an important role in Mexican cleft care through educational collaborations that complement the strengths of Mexican cleft surgeons.

Understanding patient interest in cosmetic surgery is an important tool in delineating the current market for aesthetic surgeons. Similarly, defining those factors that most influence surgeon selection is vital for optimizing marketing strategies. The authors evaluate a general population sample's interest in cosmetic surgery and investigate which factors patients value when selecting their surgeon. An anonymous questionnaire was distributed to 96 individuals in waiting rooms in nonsurgical clinics. Respondents were questioned on their ability to differentiate between a "plastic" surgeon and a "cosmetic" surgeon, their interest in having plastic surgery, and factors affecting surgeon and practice selection. Univariate and multivariate analyses were conducted to define any significant correlative relationships. Respondents consisted of 15 men and 81 women. Median age was 34.5 (range, 18-67) years. Overall, 20% were currently considering plastic surgery and 78% stated they would consider it in the future. The most common area of interest was a procedure for the face. The most important factors in selecting a surgeon were surgeon reputation and board certification. The least important were quality of advertising and surgeon age. The most cited factor preventing individuals from pursuing plastic surgery was fear of a poor result. Most (60%) patients would choose a private surgicenter-based practice. The level of importance for each studied attribute can help plastic surgeons understand the market for cosmetic surgery as well as what patients look for when selecting their surgeon. This study helps to define those attributes in a sample population.

Increasing age has traditionally been associated with impairment in wound healing after operative interventions. This is based mostly on hearsay and anecdotal information. This idea fits with the authors’ understanding of biology in older organisms. This dictum has not been rigorously tested in clinical practice. The American College of Surgeons National Surgical Quality Improvement Program database was retrospectively queried for all patients undergoing plastic surgery from 2005 to 2010. Variables extracted included basic demographics, comorbidities, previous steroid and tobacco use, wound classification at the end of the surgery, and development of postoperative surgical-site infections. Multivariate analyses were used to investigate the impact of aging in wound dehiscence. A total of 25,967 patients were identified. Overall, the incidence of wound dehiscence was 0.75 percent (n = 196). When patients younger than 30 years were compared to older patient groups, no difference in the probability of developing wound dehiscence was noted. Specifically, the groups of patients aged 61 to 70 years and older than 70 years did not have statistically significant wound healing deficiencies [adjusted OR, 0.63 (95 percent CI, 0.11 to 3.63), adjusted p = 0.609; 2.79 (0.55 to 14.18), adjusted p = 0.217, for 61 to 70 years and older than 70 years, respectively]. Factors independently associated with wound dehiscence included postoperative abscess development, paraplegia, quadriplegia, steroid and tobacco use, deep surgical-site infection development, increasing body mass index, and wound classification at the end of surgery. In patients undergoing plastic surgery, wound dehiscence is a rare complication (0.75 percent). Aging is not associated with an increased incidence of wound dehiscence. Risk, III.
There is a paucity of trained pediatric surgeons in resource-poor areas, and many children never receive care for debilitating problems that could readily be managed by surgeons with proper training, supplies, and instrumentation. This article, written from the perspective of a surgeon who has been both the recipient of and the provider of volunteer surgical services, is intended to encourage surgeons in technologically advanced locations to volunteer in underserved areas and to assist them in the implementation of such endeavors. Concepts are presented with an emphasis on pediatric surgery, but most are relevant for volunteers in all surgical specialties. Volunteer paradigms include, but are not limited to, the "surgical brigade" model, where a large group of health care professionals take all needed equipment and supplies for the duration of their stint, and the "minimalist" model, where a single volunteer works with local personnel using locally available equipment. For a successful volunteer endeavor the host needs to have a perceived need for the volunteer's services, and the volunteer must be flexible in adapting to meet overwhelming needs with limited resources. It is suggested that appropriate technology, such as the inexpensive anal stimulator presented herein, should be employed whenever possible. With proper planning, realistic expectations, and a cooperative and helpful attitude, volunteer trips can be rewarding experiences for both volunteers and host physicians and lead to lasting relationships that improve children's lives globally.

Although many older adults prefer to avoid burdensome interventions with limited ability to preserve their functional status, aggressive treatments, including surgery, are common near the end of life. Shared decision making is critical to achieve value-concordant treatment decisions and minimize unwanted care. However, communication in the acute inpatient setting is challenging. To evaluate the proof of concept of an intervention to teach surgeons to use the Best Case/Worst Case framework as a strategy to change surgeon communication and promote shared decision making during high-stakes surgical decisions. Our prospective pre-post study was conducted from June 2014 to August 2015, and data were analyzed using a mixed methods approach. The data were drawn from decision-making conversations between 32 older inpatients with an acute nonemergent surgical problem, 30 family members, and 25 surgeons at 1 tertiary care hospital in Madison, Wisconsin. A 2-hour training session to teach each study-enrolled surgeon to use the Best Case/Worst Case communication framework. We scored conversation transcripts using OPTION 5, an observer measure of shared decision making, and used qualitative content analysis to characterize patterns in conversation structure, description of outcomes, and deliberation over treatment alternatives. The study participants were patients aged 68 to 95 years (n = 32), 44% of whom had 5 or more comorbid conditions; family members of patients (n = 30); and surgeons (n = 17). The median OPTION 5 score improved from 41 preintervention (interquartile range, 26-66) to 74 after Best Case/Worst Case training (interquartile range, 60-81). Before training, surgeons described the patient's problem in conjunction with an operative solution, directed deliberation over options, listed discrete procedural risks, and did not integrate preferences into a treatment recommendation. After training, surgeons using Best Case/Worst Case clearly presented a choice between

Many surgeons experience work-related pain and musculoskeletal symptoms; however, comprehensive reporting of surgeon ailments is lacking in the literature. We sought to evaluate surgeons' work-related symptoms, possible causes of these symptoms, and to report outcomes associated with those symptoms. Five major medical indices were queried for articles published between 1980 and 2014. Included articles evaluated musculoskeletal symptoms and ergonomic outcomes in surgeons. A meta-analysis using a fixed-effect model was used to report pooled results. Forty articles with 5152 surveyed surgeons were included. Sixty-eight percent of surgeons surveyed reported generalized pain. Site-specific pain included pain in the back (50%), neck (48%), and arm or shoulder (43%). Fatigue was reported by 71% of surgeons, numbness by 37%, and stiffness by 45%. Compared with surgeons performing open surgery, surgeons performing minimally invasive surgery (MIS) were significantly more likely to experience pain in the neck (OR 2.77 [95% CI 1.30-5.93]), arm or shoulder (OR 4.59 [2.19-9.61]), hands (OR 2.99 [1.33-6.71], and legs (OR 12.34 [5.43-28.06]) and experience higher odds of fatigue (8.09 [5.60-11.70]) and numbness (6.82 [1.75-26.65]). Operating exacerbated pain in 61% of surgeons, but only 29% sought treatment for their symptoms. We found no direct association between muscles strained and symptoms. Most surgeons report work-related symptoms but are unlikely to seek medical attention. MIS surgeons are significantly more likely to experience musculoskeletal symptoms than surgeons performing open surgery. Symptoms experienced do not necessarily correlate with strain.

Although blood transfusion is a common therapeutic intervention and a mainstay of treating surgical blood loss, it may be perceived by patients and their physicians as having associated risk of adverse events. Practicing patient-centered care necessitates that clinicians have an understanding of an individual patient's perceptions of transfusion practice and incorporate this into shared medical decision-making. A paper survey was completed by patients during routine outpatient preoperative evaluation. An online survey was completed by attending anesthesiologists and surgeons at the same institution. Both surveys evaluated perceptions of the overall risk of transfusions, level of concern regarding 5 specific adverse events with transfusion, and perceptions of the frequency of those adverse events. Group differences were evaluated with conventional inferential biostatistics. A total of 294 patients and 73 physicians completed the surveys. Among the surveyed patients, 20% (95% confidence interval, 15%-25%) perceived blood transfusions as "very often risky" or "always risky." Greater perceived overall blood transfusion risk was associated with African American race (P = 0.028) and having a high school or less level of education (P = 0.022). Greater perceived risk of allergic reaction (P = 0.001), fever (P reaction (P = 0.009), fever (P = 0.039), dyspnea (P = 0.004), human immunodeficiency virus/acquired immune deficiency syndrome and hepatitis (P = 0.003), and medical error (P = 0.039) were associated with having a high school or less level of education. Patients and physicians also differed significantly in their survey responses, with physicians reporting greater overall perceived risk with a blood transfusion (P = 0.001). Despite improvements in blood transfusion safety in the United States and other developed countries, the results of this study indicate that a sizeable percentage of patients still perceive transfusion as having significant associated risk

Full Text Available Musculoskeletal injury confers an enormous burden of preventable disability and mortality in low- and moderate-income countries (LMICs. Appropriate orthopedic and trauma care services are lacking. Leading international health agencies emphasize the critical need to create and sustain research capacity in the developing world as a strategic factor in the establishment of functional, independent health systems. One aspect of building research capacity is partnership between developing and developed countries, and knowledge sharing via these collaborations. This study evaluated the efficacy of a short, intensive course designed to educate surgeons on fundamental aspects of clinical research using evidence-based medicine (EBM principles. Orthopedic surgeons from the United States and Canada presented a one-day course on the fundamentals of clinical research in Havana, Cuba. Knowledge acquisition was assessed on the part of course participants and surveyed current involvement with and attitudes toward clinical research. Questionnaires were presented to participants immediately preceding and following the course. The mean pre-test score was 43.9% (95% CI: 41.1–46.6%. The mean post-test score was 59.3% (95% CI: 56.5–62.1%. There were relative score increases in each subgroup based on professional level, subjective level of familiarity with EBM concepts, and subjective level of experience in research. This study establishes the short-term efficacy of an intensive course designed to impart knowledge in EBM and clinical research. Further study is necessary to determine the long-term benefits of this type of course. This may be a useful part of an overall strategy to build health research capacity in LMICs, ultimately contributing to improved access to high-quality surgical care.

There is a wide chasm in access to essential and emergency surgery between high and low/middle income countries (LMICs). Surgeons worldwide are integral to solutions needed to address this imbalance. Involving surgical trainees, who represent the future of surgery, is vital to this endeavour. The Association of Surgeons in Training (ASiT) is an independent charity that support surgical trainees of all ten surgical specialties in the UK and Ireland. ASiT convened a consensus meeting at the ASiT conference in Liverpool 2016 to discuss trainee engagement with global surgery, including potential barriers and solutions. A face-to-face consensus meeting reviewed the engagement of, and roles for, surgical trainees in global surgery at the ASiT Conference (Liverpool, England), March 2016. Participants self-identified based on experience and interest in the field, and included trainees (residents and students) and consultants (attending grade). Following expert review, seven pre-determined core areas were presented for review and debate. Extensive discussion was facilitated by a consultant and a senior surgical trainee, with expertise in global surgery. The draft derived from these initial discussions was circulated to all those who had participated, and an iterative process of revision was undertaken until a final consensus and recommendations were reached. There is increasing interest from trainee surgeons to work in LMICs. There are however, ethical considerations, and it is important that trainees working in LMICs undertake work appropriate to their training stage and competencies. Visiting surgeons must consider the requirements of the hosting centres rather than just their own objectives. If appropriately organised, both short and long-term visits, can enable development of transferable clinical, organisational, research and education skills. A central repository of information on global surgery would be useful to trainees, to complement existing resources. Challenges

Full Text Available Minimally invasive surgery (MIS offers cosmetic benefits to patients; however, surgeons often experience pain during MIS. We administered an ergonomic questionnaire to 176 Korean laparoscopic gynecological surgeons to determine potential sources of pain during surgery. Logistic regression analysis was used to identify factors that had a significant impact on gynecological surgeons' pain. Operating table height at the beginning of surgery and during the operation were significantly associated with neck and shoulder discomfort (P <0.001. The ability to control the operating table height was the single factor most significantly associated with neck (P <0.001 and shoulder discomfort (P <0.001. Discomfort of the hand/digits was significantly associated with the trocar site (P = 0.035. The type of electrocautery activation switch and foot pedal were significantly related to surgeons' foot and leg discomfort (P <0.001. In evaluating the co-occurrence of pain in 4 different sites (neck, shoulder, back, hand/digits, the neck and shoulder were determined to have the highest co-occurrence of pain (Spearman's ρ = 0.64, P <0.001. These results provide guidance for identifying ergonomic solutions to reduce gynecological laparoscopic surgeons' pain. Based on our results, we propose the use of an ergonomic surgical step stool to reduce physical pain related to performing laparoscopic operations.

OBJECT Patient satisfaction scores have become a common metric for health care quality. Because satisfaction scores are right-skewed, even small differences in mean scores can have a large impact. Little information, however, is available on the specific factors that play a role in satisfaction in patients with spinal disorders. The authors investigated whether disability severity and the surgeon's recommendation for or against surgical intervention were associated with patient satisfaction scores. METHODS The authors conducted a retrospective cohort study involving adult patients who were referred to a spine surgeon for an outpatient evaluation of back pain. Patients completed the Oswestry Disability Index (ODI) before their clinic appointment and a Press Ganey patient satisfaction survey after their visit. Patients were grouped by self-assessed disability severity: mild to moderate (ODI disability self-assessment. The authors also investigated whether the surgeon's recommendation against surgery negatively affected patient satisfaction. RESULTS One hundred thirty patients completed the ODI questionnaire before and satisfaction surveys after seeing a spine surgeon for a new outpatient back pain consultation. Of these, 68 patients had severe disability, 62 had mild to moderate disability, 67 received a recommendation for surgery, and 63 received a recommendation against surgery. Composite satisfaction scores were lower among patients who had severe disability than among those with mild to moderate disability (median [interquartile range]: 91.7 [83.7-96.4] vs 95.8 [91.0-99.3], respectively; p = 0.0040). Patients who received a recommendation against surgery reported lower satisfaction scores than those who received a recommendation for surgery (91.7 [83.5-95.8] vs 95.8 [88.5-99.8]; p = 0.0059). CONCLUSIONS High self-assessment of disability and a surgeon's recommendation against surgical intervention are associated with lower satisfaction scores in patients with

Review of historical archival records. Describe Harvey Cushing's patients with spinal pathology. Harvey Cushing was a pioneer of modern surgery but his work on spine remains largely unknown. Review of the Chesney Medical Archives of the Johns Hopkins Hospital from 1896 to 1912. This is the first time that Cushing's spinal cases while he was at the Johns Hopkins Hospital, including those with Pott disease, have been described.Cushing treated three young men with psoas abscesses secondary to Pott disease during his residency: he drained the abscesses, debrided any accompanying necrotic vertebral bodies, irrigated the cavity with salt, and left the incision open to close by secondary intention. Although Cushing used Koch's "tuberculin therapy" (of intravenous administration of isolated tubercular bacilli) in one patient, he did not do so in the other two, likely because of the poor response of this first patient. Later in his tenure, Cushing performed a laminectomy on a patient with kyphosis and paraplegia secondary to Pott disease. These cases provide a view of Cushing early in his career, pointing to the extraordinary degree of independence that he had during his residency under William Steward Halsted; these cases may have been important in the surgical upbringing both of Cushing and his coresident, William Stevenson Baer, who became the first professor of Orthopedics at Johns Hopkins Hospital. At the turn of the last century, Pott disease was primarily treated by immobilization with bed rest, braces, and plaster-of-paris jackets; some surgeons also employed gradual correction of the deformity by hyperextension. Patients who failed a trial of conservative therapy (of months to years) were treated with a laminectomy. However, the limitations of these strategies led to the development of techniques that form the basis of contemporary spine surgery-instrumentation and fusion.

Research has demonstrated the benefits of robotic surgery for the patient; however, research examining the benefits of robotic technology for the surgeon is limited. This study aimed to adopt validated measures of workload, mental effort, and gaze control to assess the benefits of robotic surgery for the surgeon. We predicted that the performance of surgical training tasks on a surgical robot would require lower investments of workload and mental effort, and would be accompanied by superior gaze control and better performance, when compared to conventional laparoscopy. Thirty-two surgeons performed two trials on a ball pick-and-drop task and a rope-threading task on both robotic and laparoscopic systems. Measures of workload (the surgery task load index), mental effort (subjective: rating scale for mental effort and objective: standard deviation of beat-to-beat intervals), gaze control (using a mobile eye movement recorder), and task performance (completion time and number of errors) were recorded. As expected, surgeons performed both tasks more quickly and accurately (with fewer errors) on the robotic system. Self-reported measures of workload and mental effort were significantly lower on the robotic system compared to the laparoscopic system. Similarly, an objective cardiovascular measure of mental effort revealed lower investment of mental effort when using the robotic platform relative to the laparoscopic platform. Gaze control distinguished the robotic from the laparoscopic systems, but not in the predicted fashion, with the robotic system associated with poorer (more novice like) gaze control. The findings highlight the benefits of robotic technology for surgical operators. Specifically, they suggest that tasks can be performed more proficiently, at a lower workload, and with the investment of less mental effort, this may allow surgeons greater cognitive resources for dealing with other demands such as communication, decision-making, or periods of increased

Various clinical and radiological criteria have been suggested to choose one of the numerous techniques in surgical treatment of hallux valgus and rigidus. We hypothesized that the surgeons' professional background will influence that choice depending on specialization, age, type and institution of training as well as his orthopaedic cultural orientation. Since Switzerland is characterized by regional languages (the most important being German and French), we were interested to learn if the linguistic differences had an influence on the orientation of the surgeons towards e.g. Anglo-American or French surgical traditions and/or sources of literature on the subject. A survey was e-mailed to all members of the Swiss Orthopaedic Society (SGOT-SSOT). Questions were asked regarding respondents' demographics as well as their preferred treatment for 3 separate cases of (1) moderate and (2) severe hallux valgus and (3) hallux rigidus. The responses were collected and statistically analyzed. Two hundred thirty of 322 respondents completed the survey(response rate 46 %). as they perform foot surgery on a regular base; 39 % were members of the Swiss Orthopaedic Foot and Ankle Society (SFAS). Selected surgical treatments differed as follows: in joint sparing procedures older and busier surgeons were more likely to use Chevron osteotomies, however more than 50 % preferred a Scarf-type of osteotomy. Along the so-called "Rösti-Graben" separating the French from the German speaking part of Switzerland no significant difference was found in the choice of operation technique. Nevertheless the fact being a member of SFAS showed significant differences in technical choice in case 2 and 3. There are significant associations between the surgeons' age, expertise and training and their preferred operative intervention. Considerable differences in the surgical management were found in the practice of the general orthopaedic surgeons 72 and the foot and ankle specialists. The cultural

"Academic surgeon" describes a member of a medical school department of surgery, but this term does not fully define the important role of such physician-scientists in advancing surgical science through translational research and innovation. The curriculum vitae and self-descriptive vignettes of the records of achievement of seven surgeons possessing documented records of academic leadership, innovation, and dissemination of knowledge were reviewed. Out analysis yielded seven attributes of the archetypal academic surgeon: 1) identifies complex clinical problems ignored or thought unsolvable by others, 2) becomes an expert, 3) innovates to advance treatment, 4) observes outcomes to further improve and innovate, 5) disseminates knowledge and expertise, 6) asks important questions to further improve care, and 7) trains the next generation of surgeons and scientists. Although alternative pathways to innovation and academic contribution also exist, the academic surgeon typically devotes years of careful observation, analysis, and iterative investigation to identify and solve challenging or unexplored clinical problems, ideally leverages resources available in academic medical centers to support these endeavors.

Increased longevity has led to more nonagenarians undergoing elective surgery. Development of predictive models for hospital readmission may identify patients who benefit from preoperative optimization and postoperative transition of care intervention. Our goal was to identify significant predictors of 30-d readmission in nonagenarians undergoing elective surgery. Nonagenarians undergoing elective surgery from January 2011 to December 2012 were identified using the American College of Surgeons National Surgical Quality Improvement Project participant use data files. This population was randomly divided into a 70% derivation cohort for model development and 30% validation cohort. Using multivariate step-down regression, predictive models were developed for 30-d readmission. Of 7092 nonagenarians undergoing elective surgery, 798 (11.3%) were readmitted within 30 d. Factors significant in univariate analysis were used to develop predictive models for 30-d readmissions. Diabetes (odds ratio [OR]: 1.51, 95% confidence interval [CI]: 1.24-1.84), dialysis dependence (OR: 2.97, CI: 1.77-4.99), functional status (OR: 1.52, CI: 1.29-1.79), American Society of Anesthesiologists class II or higher (American Society of Anesthesiologist physical status classification system; OR: 1.80, CI: 1.42-2.28), operative time (OR: 1.05, CI: 1.02-1.08), myocardial infarction (OR: 5.17, CI: 3.38-7.90), organ space surgical site infection (OR: 8.63, CI: 4.04-18.4), wound disruption (OR: 14.3, CI: 4.80-42.9), pneumonia (OR: 8.59, CI: 6.17-12.0), urinary tract infection (OR: 3.88, CI: 3.02-4.99), stroke (OR: 6.37, CI: 3.47-11.7), deep venous thrombosis (OR: 5.96, CI: 3.70-9.60), pulmonary embolism (OR: 20.3, CI: 9.7-42.5), and sepsis (OR: 13.1, CI: 8.57-20.1), septic shock (OR: 43.8, CI: 18.2-105.0), were included in the final model. This model had a c-statistic of 0.73, indicating a fair association of predicted probabilities with observed outcomes. However, when applied to the validation

Rural surgeons have unique learning needs not easily met by traditional continuing medical education courses. A multidisciplinary team developed and implemented a skills curriculum focused on leadership and communication, advanced endoscopy, emergency urology, emergency gynecology, facial plastic surgery, ultrasound, and management of fingertip amputations. Twenty-five of 30 (89%) rural surgeons who completed a follow-up course evaluation reported that the knowledge acquired during the course had improved their practice and/or the quality of patient care, particularly by refining commonly used skills and expanding the care options they could offer to their patients. The surgeons reported incorporating changes in their communication and interaction with colleagues. This course was successful, from participants' perspectives, in providing hands-on mentored training for a variety of skills that reflect the broad scope of practice of surgeons in rural areas. Attendees felt that their participation resulted in important behavior and practice changes. Copyright © 2014 Elsevier Inc. All rights reserved.

This is a review of Ibn al Quff's account of surgical pain relief in his surgical book Al Omdah, in which he mentioned the word anesthetic (Al moukhadder) and the involvement of physician (al tabbaaee) to give mixture of drugs to prevent pain in a surgical condition to relieve the patient from pain or to make surgical management possible. Hich indicated one rare occasion to such description in Arabic medical texts. Methods of administration of these drugs were inhalation, ingestion and by rec...

Appropriate selection of tongue cancer patients considering surgery is critical in ensuring optimal outcomes. The American College of Surgeons' National Surgical Quality Improvement Program ('ACS-NSQIP') risk calculator was developed to assess patients' 30-day post-operative risk, providing surgeons with information to guide decision making. A retrospective review of 30-day actual mortality and morbidity of tongue cancer patients was undertaken to investigate the validity of this tool for South Australian patients treated from 2005 to 2015. One hundred and twenty patients had undergone glossectomy. Predicted length of stay using the risk calculator was significantly different from actual length of stay. Predicted mortality and other complications were found to be similar to actual outcomes. The American College of Surgeons' National Surgical Quality Improvement Program risk calculator was found to be effective in predicting post-operative complication rates in South Australian tongue cancer patients. However, significant discrepancies in predicted and actual length of stay may limit its use in this population.

The learning curve in laparoscopic surgery may be associated with higher patient risk, which is unacceptable in the setting of kidney donation. Virtual reality simulators may increase the safety and efficiency of training in laparoscopic surgery. The aim of this study was to investigate if the results of a training session reflect the actual skill level of transplantation surgeons and whether the simulator could differentiate laparoscopic experienced transplantation surgeon from advanced trainees. 16 subjects were assigned to one of two groups: 5 experienced transplantation surgeon and 11 advanced residents, with only assistant role during transplantation. The level of performance was measured by a relative scoring system that combines single parameters assessed by the computer. The higher the level of transplantation experience of a participant, the higher the laparoscopic performance. Experienced transplantation surgeons showed statistically significant better scores than the advanced group for time and precision parameters. Our results show that performance of the various tasks on the simulator corresponds to the respective level of experience in transplantation surgery in our research groups. This study confirms construct validity for the LapSim. It thus measures relevant skills and can be integrated in an endoscopic training and assessment curriculum for transplantations surgeons.

In this issue of the Bulletin, the leadership of the American College of Surgeons has published a Statement on Medical and Surgical Tourism (see page 26). The statement addresses a number of concerns about this new industry and some of the safety and quality issues that patients may encounter if they seek health care services outside of the U.S. On June 16, 2008, the American Medical Association adopted its own first set of guidelines on medical tourism to help ensure the safety of patients who are considering traveling abroad for medical care. The American College of Surgeons' statement and the American Medical Association's guidelines together provide an important set of principles for consideration by patients, employers, insurers, and other third-party groups responsible for coordinating such travel outside of the country.

Basic science knowledge is a foundational element of surgical practice. Increasing surgical specialization may merit a reconsideration of the 'whole-body' approach to basic science curriculum in favour of specialty specific depth. The conundrum of depth or breadth of basic science curriculum is currently being addressed by the Royal Australasian College of Surgeons, which introduced a new surgical education and training programme for nine surgical specialties in 2008. This paper describes an innovative solution to the design of a basic science curriculum in the nine different surgical specialty streams of this programme. The task was to develop a curriculum and rigorous assessment in basic sciences to meet the needs of the training programme, for implementation within the first year. A number of political/cultural and technical issues were identified as critical to success. To achieve a robust assessment within the required time frame attention was paid to engagement, governance, curriculum definition, assessment development, and implementation. The pragmatic solution to curriculum and assessment was to use the existing assessment items and blueprint to determine a new curriculum definition and assessment. The resulting curriculum comprises a generic component, undertaken by all trainees, and specialty specific components. In a time critical environment, a pragmatic solution to curriculum, applied with predetermined, structured and meticulous methodology, allowed explicit definition of breadth for the generic basic science curriculum for surgical training in Australia and New Zealand. Implicit definition of specialty specific-basic science curricula was through the creation of a blueprinted assessment.

We explored regional variations in the surgical management of patients with Dupuytren's contracture (DC) in 12 European countries using a surgeon survey and patient chart review. Twelve countries participated: Denmark, Finland, Sweden (Nordic region); Czech Republic, Hungary, Poland (East); France, Germany, the Netherlands, UK (West); Italy, Spain (Mediterranean). For the survey, a random sample of orthopaedic/plastic surgeons (n = 687) with 3-30 years' experience was asked about DC procedures performed during the previous 12 months. For the chart review (n = 3357), information from up to five consecutive patients was extracted. Descriptive statistics are reported. Ninety-five per cent of all surgeons used fasciectomy for DC, followed by fasciotomy (70%), dermofasciectomy (38%) and percutaneous needle fasciotomy (35%). Most surgeons were satisfied with fasciectomy over other procedures. Recommended time away from work and duration of physical therapy increased with the invasiveness of the procedure. The intra-operative complication rate was 4.0%; the postoperative complication rate was 34%. Overall, ≥ 97% of the procedures were rated by surgeons as having a positive outcome. Across all regions, 54% of patients had no nodules or contracture after the procedures. Only 2% of patients required retreatment within the first year of surgery. Important inter- and intraregional differences in these aspects of patient management are described. Understanding current regional treatment patterns and their relationships to country-specific health systems may facilitate earlier identification of, and intervention for, DD and help to optimise the overall treatment for patients with this chronic condition. © 2013 Blackwell Publishing Ltd.

Laparoscopic surgery presents multiple ergonomic difficulties for the surgeon, requiring awkward body postures and prolonged static muscle loading that increases risk of musculoskeletal strain and injury. This prospective study quantitatively measures the biomechanical movements of surgeons during laparoscopic procedures to determine at-risk movements from prolonged static muscle loading and repetitive motions that may lead to injury. A total of 150 video recordings of 18 surgeons, standing at the patient's left, were captured from three fixed camera positions during live gynecological laparoscopic surgery. Postoperative processing quantified surgeon movements at the neck, shoulders and elbows using computer software to measure extreme joint angles and time spent within defined joint angle ranges. Surgeons spent a median of 98 % (range 77-100 %) of surgical time with their neck rotated at 21° (range 0°-52°). The non-dominant arm was subjected to more extreme positions for significantly longer periods of time compared to the dominant, with shoulder flexion at 45°-90° for 35 vs. 0 % (p 120° for 31 vs. 0 % (p 90° (p = 0.04) and elbow at >120° (p movements that increase their risk of harm: (1) extended periods of neck rotation; (2) asymmetrical loading between the dominant and non-dominant shoulders; (3) power morcellation and frequent insertions/removals of laparoscopic instruments resulting in repetitions of the most extreme shoulder positions and (4) a negative correlation between height and percentage time spent in more extreme positions.

Background Hallux valgus is one of the most prevalent foot deformities, and surgical treatment of Hallux valgus is one of the most common procedures in foot and ankle surgery. Diagnostic and treatment standards show large variation despite medical guidelines and national foot and ankle societies. The aim of this nationwide survey is a description of the current status of diagnostics and therapy of Hallux valgus in Germany. Material and Methods A nationwide online questionnaire survey was sent to two German foot and ankle societies. The participants were asked to answer a questionnaire of 53 questions with four subgroups (general, diagnostics, operation, preoperative management). Surgical treatment for three clinical cases demonstrating a mild, moderate and severe Hallux valgus deformity was inquired. Results 427 foot and ankle surgeons answered the questionnaire. 388 participants were certified foot and ankle surgeons from one or both foot and ankle societies. Medical history (78%), preoperative radiographs (100%) and preoperative radiographic management (78%) are of high or very high importance for surgical decision pathway. Outcome scores are used by less than 20% regularly. Open surgery is still the gold standard, whereas minimally invasive surgery is performed by only 7%. Conclusion Our survey showed that diagnostic standards are met regularly. There is a wide variation in the type of procedures used to treat Hallux valgus deformity. TMT I arthrodesis is preferred in severe Hallux valgus, but also used to treat moderate and mild deformities. Minimally invasive surgery is still used by a minority of surgeons. It remains to be seen, to what extent minimally invasive surgery will be performed in the future. Georg Thieme Verlag KG Stuttgart · New York.

Despite diffusion of laparoscopic hepatectomy, the acquisition of necessary skills is not easy for open liver surgeons. Concepts and techniques have totally changed in laparoscopic hepatectomy compared with open hepatectomy, which is an underlying cause of a technical hurdle in laparoscopic hepatectomy. This study aimed to illustrate laparoscopy-specific concepts and techniques for hepatectomy. Video footages of laparoscopic and open hepatectomies stored in the Institut Mutualiste Montsouris and Kyoto University were reviewed to define the differences in surgical view, surgical concept, and technical details, using left lateral sectionectomy (LLS) and right hepatectomy (RH) as representative examples. By comparison with open LLS and RH, laparoscopy-specific procedures were identified with regard to surgical view, parenchymal transection, available landmarks, and vascular dissection. By laparoscopy, the surgical field was constantly viewed and accessed from the caudal side to the cranial side. Similarly, the parenchyma was divided, and intrahepatic vessels were dissected in the same direction. Laparoscopy-specific landmarks were identified for both LLS and RH, behind the liver. The concepts and techniques in laparoscopic hepatectomy are totally different from those of open hepatectomy because of the different surgical views. Understanding the laparoscopy-specific concepts and techniques would facilitate safe and efficient execution of laparoscopic hepatectomy.

(1) Define the epidemiologic trend of distal clavicle excision (DCE) for acromioclavicular (AC) joint arthritis among board-eligible orthopaedic surgeons in the United States, (2) describe the rates and types of reported complications of open and arthroscopic DCE, and (3) evaluate the effect of fellowship training on preferred technique and reported complication rates. The American Board of Orthopaedic Surgery (ABOS) database was used to identify DCE cases submitted by ABOS Part II Board Certification examination candidates. Inclusion criteria were predetermined using a combination of ICD-9 and CPT codes. Cases were dichotomized into 2 groups: open or arthroscopic DCE. The 2 groups were then analyzed to determine trends in annual incidence, complication rates, and surgeon fellowship training. From April 2004 to September 2013, there were 3,229 open and 12,782 arthroscopic DCE procedures performed and submitted by ABOS Part II Board Eligible candidates. Overall, the annual incidence of open DCE decreased (78-37 cases per 10,000 submitted cases, P = .023). Although the annual number of arthroscopic DCE remained steady (1160-1125, P = .622), the percentage of DCE cases performed arthroscopically increased (65%-79%, P = .033). Surgeons without fellowship training were most likely to perform a DCE via an open approach (31%) whereas surgeons with sports medicine training were more likely to perform DCE arthroscopically compared with other fellowship groups (88%, P board-eligible orthopaedic surgeons, possibly because of an increased complication rate associated with open treatment. Fellowship training was significantly associated with the type of treatment (open vs arthroscopic) rendered and complication rates. Level IV, case series.

To investigate the use of machine learning to empirically determine the risk of individual surgical procedures and to improve surgical models with this information. American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) data from 2005 to 2009 were used to train support vector machine (SVM) classifiers to learn the relationship between textual constructs in current procedural terminology (CPT) descriptions and mortality, morbidity, Clavien 4 complications, and surgical-site infections (SSI) within 30 days of surgery. The procedural risk scores produced by the SVM classifiers were validated on data from 2010 in univariate and multivariate analyses. The procedural risk scores produced by the SVM classifiers achieved moderate-to-high levels of discrimination in univariate analyses (area under receiver operating characteristic curve: 0.871 for mortality, 0.789 for morbidity, 0.791 for SSI, 0.845 for Clavien 4 complications). Addition of these scores also substantially improved multivariate models comprising patient factors and previously proposed correlates of procedural risk (net reclassification improvement and integrated discrimination improvement: 0.54 and 0.001 for mortality, 0.46 and 0.011 for morbidity, 0.68 and 0.022 for SSI, 0.44 and 0.001 for Clavien 4 complications; P risk for individual procedures. This information can be measured in an entirely data-driven manner and substantially improves multifactorial models to predict postoperative complications. Copyright © 2014 Elsevier Inc.

The USA devotes roughly $200 billion (6%) of annual national health expenditures to medical devices. A substantial proportion of this spending occurs during orthopedic (eg, hip and knee) arthroplasties - two high-volume hospital procedures. The implants used in these procedures are commonly known as physician preference items (PPIs), reflecting the physician's choice of implant and vendor used. The foundations for this preference are not entirely clear. This study examines what implant and vendor characteristics, as evaluated by orthopedic surgeons, are associated with their preference. It also examines other factors (eg, financial relationships and vendor tenure) that may contribute to implant preference. We surveyed all practicing orthopedic surgeons performing 12 or more implant procedures annually in the Commonwealth of Pennsylvania. The survey identified each surgeon's preferred hip/knee vendor as well as the factors that surgeons state they use in selecting that primary vendor. We compared the surgeons' evaluation of multiple characteristics of implants and vendors using analysis of variance techniques, controlling for surgeon characteristics, hospital characteristics, and surgeon-vendor ties that might influence these evaluations. Physician's preference is heavily influenced by technology/implant factors and sales/service factors. Other considerations such as vendor reputation, financial relationships with the vendor, and implant cost seem less important. These findings hold regardless of implant type (hip vs knee) and specific vendor. Our results suggest that there is a great deal of consistency in the factors that surgeons state they use to evaluate PPIs such as hip and knee implants. The findings offer an empirically derived definition of PPIs that is consistent with the product and nonproduct strategies pursued by medical device companies. PPIs are products that surgeons rate favorably on the twin dimensions of technology and sales/service.

Educating residents in the operating room requires balancing patient safety, operating room efficiency demands, and resident learning needs. This study explores 4 factors that influence the amount of autonomy supervising surgeons afford to residents. We evaluated 7,297 operations performed by 487 general surgery residents and evaluated by 424 supervising surgeons from 14 training programs. The primary outcome measure was supervising surgeon autonomy granted to the resident during the operative procedure. Predictor variables included resident performance on that case, supervising surgeon history with granting autonomy, resident training level, and case difficulty. Resident performance was the strongest predictor of autonomy granted. Typical autonomy by supervising surgeon was the second most important predictor. Each additional factor led to a smaller but still significant improvement in ability to predict the supervising surgeon's autonomy decision. The 4 factors together accounted for 54% of decision variance (r = 0.74). Residents' operative performance in each case was the strongest predictor of how much autonomy was allowed in that case. Typical autonomy granted by the supervising surgeon, the second most important predictor, is unrelated to resident proficiency and warrants efforts to ensure that residents perform each procedure with many different supervisors.

Full Text Available Introduction : Surgical resection is the only potentially curative modality for gastric cancer and it is associated with substantial morbidity and mortality. Aim: To determine risk factors for postoperative morbidity and mortality following major surgery for gastric cancer. Material and methods : Between 1.08.2006 and 30.11.2014 in the Department of Oncological Surgery of Gdynia Oncology Centre 162 patients underwent gastric resection for adenocarcinoma. All procedures were performed by 13 surgeons. Five of them performed at least two gastrectomies per year (n = 106. The remaining 56 resections were done by eight surgeons with annual volume lower than two. Perioperative mortality was defined as every in-hospital death and death within 30 days after surgery. Causes of perioperative deaths were the matter of in-depth analysis. Results: Overall morbidity was 23.5%, including 4.3% rate of proximal anastomosis leak. Mortality rate was 4.3%. Morbidity and mortality were not dependent on: age, gender, body mass index, tumour location, extent of surgery, splenectomy performance, or pTNM stage. The rates of morbidity (50% vs. 21.3% and mortality (16.7% vs. 3.3% were significantly higher in cases of tumour infiltration to adjacent organs (pT4b. Perioperative morbidity and mortality were 37.5% and 8.9% for surgeons performing less than two gastrectomies per year and 16% and 0.9% for surgeons performing more than two resections annually. The differences were statistically significant (p = 0.002, p = 0.003. Conclusions : Annual surgeon case load and adjacent organ infiltration (pT4b were significant risk factors for morbidity and mortality following major surgery for gastric cancer. The most common complications leading to perioperative death were cardiac failure and proximal anastomosis leak.

This is a review of Ibn al Quff's account of surgical pain relief in his surgical book Al Omdah, in which he mentioned the word anesthetic (Al moukhadder) and the involvement of physician (al tabbaaee) to give mixture of drugs to prevent pain in a surgical condition to relieve the patient from pain or to make surgical management possible. Hich indicated one rare occasion to such description in Arabic medical texts. Methods of administration of these drugs were inhalation, ingestion and by rectal suppositories. The drugs used in anesthetic sponges include all the drugs that are recorded in the modern literature of anesthesia. They are as follows: opium, mandrake, Hyocymus albus, belladonna, Cannabis sativus, Cannabis indica, wild lettuce. The anesthetic sponge, mentioned in many references as an inhalation method, may be of symbolic value to surgery. PMID:25885079

Some argue that the specialty of plastic surgery is facing a changing identity. Challenged by factors such as increasing competition in the cosmetic marketplace and decreasing reimbursement for reconstructive procedures, many American plastic surgeons have increasingly adopted cosmetic-focused practices. The present study investigated the currently unknown practice profiles of Canadian plastic surgeons to determine the reconstructive-cosmetic mix, as well as factors that influence practice type to determine whether a similar pattern exists in Canada. An anonymous online survey regarding practice profiles was distributed to all 352 Canadian plastic surgeons with e-mail accounts registered with the Canadian Society of Plastic Surgeons and/or the Canadian Society for Aesthetic Plastic Surgery. The survey response rate was 34% (120 responses), of which 75% of respondents currently had a reconstructive practice and 25% had a cosmetic practice. Reconstructive surgeons had more educational debt following their training, spent more time on emergency call, academics and teaching and, when deciding which type of practice to establish, were more influenced by academic opportunities and less influenced by financial and nonfinancial metrics. Similarities between the groups included hours worked per week and academic achievements. The field of reconstructive plastic surgery appears to be thriving in Canada. While a transition from reconstructive to cosmetic practice is common, compared with their American colleagues, a greater proportion of Canadian plastic surgeons maintain reconstructive practices. Differences between reconstructive and cosmetic plastic surgeons are discussed.

High referral volumes to paediatric orthopaedic surgeons create long clinic waiting lists. The use of extended scope roles for doctors and health professionals is one strategy to address these wait times. We completed a 6-month trial of a non-surgical paediatric orthopaedic physician role (NSP) to help manage non-urgent referrals to our service from local general practitioners (GPs). For a 6-month period, the majority of non-urgent GP referrals were assessed by a US-trained NSP. Wait times were compared between this period and the same time period in the previous year. Family and referrer satisfaction was determined through postal surveys. Over the trial period, the NSP saw a total of 155 new patient referrals, which represented 49% of all non-urgent GP referrals for the period. Before the trial, only 75% of non-urgent referrals were seen within 131 days (19 weeks) with 10% waiting more than 215 days (31 weeks). By the end of the trial, 75% of referrals were seen within 55 days (8 weeks) and 90% within 61 days (9 weeks). The most common outcome was discharge with management advice. 12% of patients were referred on to an orthopaedic surgeon but only 1% went on to a surgical wait list. Families and referrers reported high levels of satisfaction and only three patients discharged by the NSP were referred back for orthopaedic surgeon review. The NSP role was effective at reducing clinic wait times for patients with non-urgent paediatric orthopaedic conditions, while maintaining family and referrer satisfaction. © 2014 The Authors.

Simulation can enhance learning effectiveness, efficiency, and patient safety and is engaging for learners. A survey was conducted of surgical clerkship directors nationally and medical students at 5 medical schools to rank and stratify simulation-based educational topics. Students applying to surgery were compared with others using Wilcoxon's rank-sum tests. Seventy-three of 163 clerkship directors (45%) and 231 of 872 students (26.5%) completed the survey. Of students, 28.6% were applying for surgical residency training. Clerkship directors and students generally agreed on the importance and timing of specific educational topics. Clerkship directors tended to rank basic skills, such as examination skills, higher than medical students. Students ranked procedural skills, such as lumbar puncture, more highly than clerkship directors. Surgery clerkship directors and 4th-year medical students agree substantially about the content of a simulation-based curriculum, although 4th-year medical students recommended that some topics be taught earlier than the clerkship directors recommended. Students planning to apply to surgical residencies did not differ significantly in their scoring from students pursuing nonsurgical specialties. Copyright © 2014 Elsevier Inc. All rights reserved.

Fire in the operating room is a life-threatening emergency that demands quick, efficient intervention. Because the circumstances surrounding fires are generally well-understood, virtually every operating room fire is preventable. Before every operating room case, thorough preprocedure "time outs" should address each team members' awareness of specific fire risks and agreement regarding fire concerns and emergency actions. Fire prevention centers on 3 constituent parts of the fire triad necessary for fire formation. Regular fire drills should guide policies and procedures to prevent surgical fires. Delivering optimal patient care in emergent situations requires surgical team training, practicing emergency roles, and specific actions. Copyright © 2016 Elsevier Inc. All rights reserved.

Work engagement has become a topic of great interest in recent years. However, clinicians' work engagement has rarely been studied and relatively little is known about its predictors and consequences. Therefore the objective of this cross-sectional questionnaire study was to test a model of possible institutional and personal predictors and significant relations to job and life satisfaction. 123 clinicians specializing in Surgery Medicine participated in the study. Self-administered questionnaires, including the Copenhagen Psychosocial Questionnaire, the Utrecht Work Engagement Scale, the Brief Resilient Coping Scale and the Questionnaire for Self-efficacy, Optimism and Pessimism, were administered. Bivariate analyses and a stepwise regression analysis were performed. The whole sample of surgeons rated work engagement with a high mean of M = 4.38; SD = .91. Job satisfaction and perceived quality of life have been rated with moderate scores. The results show that job resources have a greater impact on surgeons' work engagement than their job demands. Significant correlations between surgeons' work engagement, their job satisfaction and quality of life were found. Moreover, work engagement mediated the relation between institutional factors and surgeons' job satisfaction. Our research suggests that strengthening surgeons' work engagement will contribute to a more sustainable workplace, in terms of both individual and hospital performance. Therefore, increasing work engagement among surgeons should be of concern for supervisors and hospital managers. Future research should focus on further predictors that may have an influence on health professionals' work engagement. Another field for future research is to study potential effects of interventions on work engagement.

Patient demand and increasing cost awareness have led to the creation of surgical risk calculators that attempt to predict the likelihood of adverse events and to facilitate risk mitigation. The American College of Surgeons National Surgical Quality Improvement Program Surgical Risk Calculator is an online tool available for a wide variety of surgical procedures, and has not yet been fully evaluated in total joint arthroplasty. A single-center, retrospective review was performed on 909 patients receiving a unilateral primary total knee (496) or hip (413) arthroplasty between January 2012 and December 2014. Patient characteristics were entered into the risk calculator, and predicted outcomes were compared with observed results. Discrimination was evaluated using the receiver-operator area under the curve (AUC) for 90-day readmission, return to operating room (OR), discharge to skilled nursing facility (SNF)/rehab, deep venous thrombosis (DVT), and periprosthetic joint infection (PJI). The risk calculator demonstrated adequate performance in predicting discharge to SNF/rehab (AUC 0.72). Discrimination was relatively limited for DVT (AUC 0.70, P = .2), 90-day readmission (AUC 0.63), PJI (AUC 0.67), and return to OR (AUC 0.59). Risk score differences between those who did and did not experience discharge to SNF/rehab, 90-day readmission, and PJI reached significance (P Calculator has fair utility in predicting discharge to SNF/rehab, but limited usefulness for 90-day readmission, return to OR, DVT, and PJI. Although length of stay predictions are similar to actual outcomes, statistical correlation remains relatively weak. Copyright © 2017 Elsevier Inc. All rights reserved.

The choice of surgical repair or conservative treatment for iatrogenic tracheobronchial rupture (ITBR) remains controversial. However, thoracic surgeons consider that surgical repair is an important treatment modality. The purpose of this study was to evaluate the clinical results from the perspective of the surgery-preferred group. We treated 11 patients (8 women and 3 men; age: 52.6 ± 22.9 years) with ITBR from January 2011 to January 2016. A posterolateral thoracotomy or a trans-tracheal approach was performed according to the mechanism of injury. Nine patients underwent surgery, and all patients received primary repair. Five patients received a right posterolateral thoracotomy, whereas one patient received a left posterolateral thoracotomy. No mortality or morbidity related to the surgery was observed. The mechanical ventilation time was 65.9 ± 99.2 hours. The intensive care unit duration was 19.7 ± 33.3 days. Two patients received conservative treatment, and all patients died of another disease that was not related to the conservative treatment. Our mortality or morbidity due to surgery was not higher than world literature results of conservative treatment. We thought surgery is the primary treatment choice for ITBR in the absence of a good indication for conservative treatment.

OBJECTIVE If left untreated, occipitocervical (OC) instability may lead to serious neurological injury or death. Open internal fixation is often necessary to protect the neurovascular elements. This study reviews the etiologies for pediatric OC instability, analyzes the radiographic criteria for surgical intervention, discusses surgical fixation techniques, and evaluates long-term postoperative outcomes based on a single surgeon's experience. METHODS The charts of all patients atlantooccipital dislocation. The median number of fixated segments was 5 (occiput-C4). Structural bone grafts were used in all patients. Postsurgical neurological improvement was seen in 88.2% (15/17) of patients with chronic myelopathy and in 25% (1/4) of patients with acute myelopathy. Preoperatively, 42.5% (17/40) of patients were neurologically intact and remained unchanged at last follow-up, 42.5% (17/40) had neurological improvement, 12.5% (5/40) remained unchanged, and 2.5% (1/40) deteriorated. All patients had successful fusion at 1-year follow-up. The complication rate was 7.5% (3/40), including 1 case of vertebral artery injury. CONCLUSIONS Occipitocervical fixation is safe in children and provides immediate immobilization, with excellent survival and arthrodesis rates. Of the radiographic tools evaluated, the condyle-C1 interval was the most predictive of atlantooccipital dislocation.

Outdated communication technologies in healthcare can place patient safety at risk. This study aimed to evaluate implementation of the WhatsApp messaging service within emergency surgical teams. A prospective mixed-methods study was conducted in a London hospital. All emergency surgery team members (n = 40) used WhatsApp for communication for 19 weeks. The initiator and receiver of communication were compared for response times and communication types. Safety events were reported using direct quotations. More than 1,100 hours of communication pertaining to 636 patients were recorded, generating 1,495 communication events. The attending initiated the most instruction-giving communication, whereas interns asked the most clinical questions (P communication compared to the intern and attending (P communication technology.

Medical students and surgical trainees differ considerably in both their preferential learning styles and personality traits. This study compares the personality profiles and learning styles of surgical trainees with a cohort of medical students specifically intent on pursuing a surgical career. A cross-sectional study was conducted contrasting surgical trainees with medical students specifying surgical career intent. The 50-item International Personality Item Pool Big-Five Factor Marker (FFM) questionnaire was used to score 5 personality domains (extraversion, conscientiousness, agreeableness, openness to experience, and neuroticism). The 24-item Learning Style Inventory (LSI) Questionnaire was used to determine the preferential learning styles (visual, auditory, or tactile). χ(2) Analysis and independent samples t-test were used to compare LSI and FFM scores, respectively. Surgical trainees from several UK surgical centers were contrasted to undergraduate medical students. A total of 53 medical students who had specifically declared desire to pursue a surgical career and were currently undertaking an undergraduate intercalated degree in surgical sciences were included and contrasted to 37 UK core surgical trainees (postgraduate years 3-4). The LSI questionnaire was completed by 53 students and 37 trainees. FFM questionnaire was completed by 29 medical students and 34 trainees. No significant difference for learning styles preference was detected between the 2 groups (p = 0.139), with the visual modality being the preferred learning style for both students and trainees (69.8% and 54.1%, respectively). Neuroticism was the only personality trait to differ significantly between the 2 groups, with medical students scoring significantly higher than trainees (2.9 vs. 2.6, p = 0.03). Medical students intent on pursuing a surgical career exhibit similar personality traits and learning styles to surgical trainees, with both groups preferring the visual learning modality
Full Text Available Background and purpose: Surgery is a high risk profession owing to musculoskeletal disorders (MSDs. Fine and precise operations cause surgeons to adopt prolonged fixed posture. As there is limited information in this region, the purpose of this study was to determine the frequency of MSDs and personal and occupational risk factors among surgeons in Babol (a northern city in Iran. Materials and methods: This cross-sectional study was conducted on 45 surgeons during 2011 using a questionnaire in three parts including: Demographic and occupational data, Nordic standardized musculoskeletal disorders questionnaire (NMQ, and Body Discomfort Assessment technique. The working posture during operation was assessed by Rapid Entire Body Assessment (REBA. The data were analyzed using descriptive statistical indexes and chi- square test, and a p<0.05 was considered as significant. Results: According to the data, the mean of work experience was 19.9±6 years, and the mean of work hours was 54.2±14 (ranged 20-80 hours per week. Ninety five percent of surgeons reported experiencing one or more MSDs symptoms during the previous year. Neck pain (66.7% and low back pain (LBP (51% was the more frequent reported complaint. The results showed a significant statistical difference between LBP with weekly regular exercise and work experience. Conclusion: The results indicate that MSDs are the common problems among the surgeons and they are at risk because of their personal and occupational conditions. So, ergonomics interventions in order to prevent MSDs are recommended.

We reported phonatory recovery in the majority of 88 patients after recurrent laryngeal nerve (RLN) reconstruction. Here we analyzed factors that might influence the recovery, in a larger patient series. At Kuma Hospital, 449 patients (354 females and 95 males) underwent RLN reconstruction with direct anastomosis, ansa cervicalis-to-RLN anastomosis, free nerve grafting, or vagus-to-RLN anastomosis; 47.4 % had vocal cord paralysis (VCP) preoperatively. Maximum phonation time (MPT) and mean airflow rate during phonation (MFR) were measured 1 year post surgery. Forty patients whose unilateral RLNs were resected and not reconstructed and 1257 normal subjects served as controls. Compared to the VCP patients, the RLN reconstruction patients had significantly longer MPTs 1 year after surgery, nearing the normal values. The MFR results were similar but less clear. Detailed analyses of 228 female patients with reconstruction for whom data were available revealed that none of the following factors significantly affected phonatory recovery: age, preoperative VCP, method of reconstruction, site of distal anastomosis, use of magnifier, thickness of suture thread, and experience of surgeon. Of these 228 patients, 24 (10.5 %) had MPTs <9 s 1 year after surgery, indicating insufficient recovery in phonation. This insufficiency was also not associated with the factors mentioned above. Approximately 90 % of patients who needed resection of the RLN achieved phonatory recovery following RLN reconstruction. The recovery was not associated with gender, age, preoperative VCP, surgical method of reconstruction, or experience of the surgeon. Performing reconstruction during thyroid surgery is essential whenever the RLN is resected.

Despite advances in the medical management of secondary hyperparathyroidism due to chronic renal failure and dialysis (renal hyperparathyroidism), parathyroid surgery remains an important treatment option in the spectrum of the disease. Patients with severe and complicated renal hyperparathyroidism (HPT), refractory or intolerant to medical therapy and patients with specific requirements in prospect of or excluded from renal transplantation may require parathyroidectomy for renal hyperparathyroidism. Present standard and actual controversial issues regarding surgical treatment of patients with hyperparathyroidism due to chronic renal failure were identified, and pertinent literature was searched and reviewed. Whenever applicable, evaluation of the level of evidence concerning diagnosis and management of renal hyperparathyroidism according to standard criteria and recommendation grading were employed. Results were discussed at the 6th Workshop of the European Society of Endocrine Surgeons entitled Hyperparathyroidism due to multiple gland disease: An evidence-based perspective. Presently, literature reveals scant data, especially, no prospective randomized studies to provide sufficient levels of evidence to substantiate recommendations for surgery in renal hyperparathyroidism. Appropriate surgical management of renal hyperparathyroidism involves standard bilateral exploration with bilateral cervical thymectomy and a spectrum of four standardized types of parathyroid resection that reveal comparable outcome results with regard to levels of evidence and recommendation. Specific patient requirements may favour one over the other procedure according to individualized demands. Surgery for patients with renal hyperparathyroidism in the era of calcimimetics continues to play an important role in selected patients and achieves efficient control of hyperparathyroidism. The overall success rate and long-term control of renal hyperparathyroidism and optimal handling of

Low back pain (LBP) is a common and costly occupational injury among health care professionals. The purpose of this study was to investigate the prevalence and risk factors of LBP in surgeons and to analyze how individual and occupational characteristics contribute to the risk of LBP. A cross sectional study was conducted on 250 randomly selected surgeons including 112 general surgeons, 95 gynecologists and 43 orthopedists from 21 hospitals at northern Iran. A structured questionnaire including demographic, lifestyle, occupational characteristics as well as prevalence and risk factors of LBP was used. Visual analogue scale and Oswestry low back disability questionnaires were also used to assess the pain intensity and functional disability, respectively. Point, last month, last six months, last year and lifetime prevalence of LBP was 39.9%, 50.2%, 62.3%, 71.7% and 84.8%, respectively. The highest point prevalence was related to the gynecologists with 44.9%, and the lowest for general surgeons (31.7%). Age, body mass index, smoking, general health, having an assistant, job satisfaction, using preventive strategies and years of practice were found to be correlated with the prevalence of LBP (P chiropractic, and general medicine, should be performed.

Benefits of 3D printing techniques, biomodeling and surgical guides are well known in surgery, especially when the same surgeon who performed the surgery participated in the virtual surgical planning. Our objective was to evaluate the transfer of know how of a neutral 3D surgical modeling free open-source software protocol to surgeons with different surgical specialities. A one-day training session was organised in 3D surgical modeling applied to one mandibular reconstruction case with fibula free flap and creation of its surgical guides. Surgeon satisfaction was analysed before and after the training. Of 22 surgeons, 59% assessed the training as excellent or very good and 68% considered changing their daily surgical routine and would try to apply our open-source software protocol in their department after a single training day. The mean capacity in using the software improved from 4.13 on 10 before to 6.59 on 10 after training for OsiriX ® software, from 1.14 before to 5.05 after training for Meshlab ® , from 0.45 before to 4.91 after training for Netfabb ® and from 1.05 before and 4.41 after training for Blender ® . According to surgeons, using the software Blender ® became harder as the day went on. Despite improvement in the capacity in using software for all participants, more than a single training day is needed for the transfer of know how on 3D modeling with open-source software. Although the know-how transfer, overall satisfaction, actual learning outcomes and relevance of this training were appropriated, a longer training including different topics will be needed to improve training quality.

Utilizing Open Payments data, we aimed to determine the prevalence of industry payments to orthopedic and neurospine surgeons, report the magnitude of those relationships, and help outline the surgeon demographic factors associated with industry relationships. Previous Open Payments data revealed that orthopedic surgeons receive the highest value of industry payments. No study has investigated the financial relationship between spine surgeons and industry using the most recent release of Open Payments data. A database of 5898 spine surgeons in the United States was derived from the Open Payments website. Demographic data were collected, including the type of residency training, years of experience, practice setting, type of medical degree, place of training, gender, and region of practice. Multivariate generalized linear mixed models were utilized to determine the relationship between demographics and industry payments. A total of 5898 spine surgeons met inclusion criteria. About 91.6% of surgeons reported at least one financial relationship with industry. The median total value of payments was $994.07. Surgeons receiving over $1,000,000 from industry during the reporting period represented 6.6% of the database and accounted for 83.5% of the total value exchanged. Orthopedic training (P Financial relationships between spine surgeons and industry are highly prevalent. Surgeon demographics have a significant association with industry-surgeon financial relationships. Our reported value of payments did not include ownership or research payments and thus likely underestimates the magnitude of these financial relationships. 3.

To assess the true conditions and perceptions of the personal lives of men and women working as surgeons in Japan. In 2014, all e-mail subscribed members of the Japan Surgical Society (JSS, n = 29,861) were invited to complete a web-based survey. The questions covered demographic information, work environment, and personal life (including marital status, childcare, and nursing care for adult family members). In total, 6211 surgeons (5586 men and 625 women) returned the questionnaires, representing a response rate of 20.8%. Based on the questionnaire responses, surgeons generally prioritize work and spend most of their time at work, although women with children prioritize their family over work; men spend significantly fewer hours on domestic work/childcare than do their female counterparts (men 0.76 h/day vs. women 2.93 h/day, p < 0.01); and both men and women surgeons, regardless of their age or whether they have children, place more importance on the role of women in the family. The personal lives of Japanese surgeons differed significantly according to gender and whether they have children. The conservative idea that women should bear primary responsibility for the family still pertains for both men and women working as surgeons in Japan.
Full Text Available Surgical site infections (SSI following total hip arthroplasty (THA have a significantly adverse impact on patient outcomes and pose a great challenge to the treating surgeon. Therefore, timely recognition of those patients at risk for this complication is very important, as it allows for adopting measures to reduce this risk. This review discusses literature reported risk factors for SSI after THA. These can be classified into patient-related factors (age, gender, obesity, comorbidities, history of infection, primary diagnosis, and socioeconomic profile, surgery-related factors (allogeneic blood transfusion, DVT prophylaxis and coagulopathy, duration of surgery, antibiotic prophylaxis, bearing surface and fixation, bilateral procedures, NNIS index score, and anesthesia type, and hospital-related factors (duration of hospitalization, institution and surgeon volume, and admission from a healthcare facility. All these factors are discussed with respect to potential measures that can be taken to reduce their effect and consequently the overall risk for infection.

Adequate surgical care of patients and concurrent training of residents is achieved in elective procedures through careful case selection and adequate supervision. Whether this applies when trainees are involved in emergency operations remains equivocal. The aim of this study was therefore to compare the risk of post-operative complications following emergency procedures performed by senior operators compared with supervised trainees. This is a retrospective cohort study examining in-hospital deaths of patients across all surgical specialties who underwent emergency surgery in Australian public hospitals reported to the national surgical mortality audit between 2009 and 2015. Multivariable logistic regression was used to explore whether there was an association between the level of operator experience (senior operator vs trainee) and the occurrence of post-operative surgical complications following an emergency procedure. Our population consisted of 6920 patients. There were notable differences between the trainees and senior operator groups; trainees more often operated on patients aged over 80 years, with cardiovascular and neurological risk factors. Senior operators more often operated on very young and obese patients with advanced malignancy and hepatic disease. Supervised trainees had a lower rate of post-operative complications compared with senior operators; 18% (n = 396) and 25% (n = 1210), respectively (p emergency operations, provided that cases are judiciously selected.

Minimally invasive surgery (MIS) offers cosmetic benefits to patients; however, surgeons often experience pain during MIS. We administered an ergonomic questionnaire to 176 Korean laparoscopic gynecological surgeons to determine potential sources of pain during surgery. Logistic regression analysis was used to identify factors that had a significant impact on gynecological surgeons' pain. Operating table height at the beginning of surgery and during the operation were significantly associated...

Hysterectomy is the most frequent surgery done with robotic assistance in the world and has been widely studied since its emergence. The surgical outcomes of the robotic hysterectomy are similar to those obtained with other minimally invasive hysterectomy techniques (laparoscopic and vaginal) and appear as a promising surgical technique in gynecology surgery. The aim of this study was to observe the learning curve of robot-assisted hysterectomy in a French surgical center, and was to evaluate the impact of the surgical mentoring. We retrospectively collected the data from the files of the robot-assisted hysterectomies with the Da Vinci ® Surgical System performed between March 2010 and June 2014 at the Foch hospital in Suresnes (France). We first studied the operative time according to the number of cases, independently of the surgeon to determine two periods: the initial learning phase (Phase 1) and the control of surgical skills phase (Phase 2). The phase was defined by mastering the basic surgical tasks. Secondarily, we compared these two periods for operative time, blood losses, body mass index (BMI), days of hospitalizations, and uterine weight. We, finally, studied the difference of the learning curve between an experimented surgeon (S1) who practiced first the robot-assisted hysterectomies and a less experimented surgeon (S2) who first assisted S1 and then operated on his own patients. A total of 154 robot-assisted hysterectomies were analyzed. Twenty procedures were necessary to access to the control of surgical skills phase. There was a significant decrease of the operative time between the learning phase (156.8 min) compared to the control of surgical skills phase (125.8 min, p = 0.003). No difference between these two periods for blood losses, BMI, days of hospitalizations and uterine weight was demonstrated. The learning curve of S1 showed 20 procedures to master the robot-assisted hysterectomies with a significant decrease of the operative

Promoting a culture of teaching may encourage students to choose a surgical career. Teaching in a human factors (HF) curriculum, the nontechnical skills of surgery, is associated with surgeons' stronger identity as teachers and with clinical students' improved perception of surgery and satisfaction with the clerkship experience. To describe the effects of an HF curriculum on teaching culture in surgery. Surgeons and educators developed an HF curriculum including communication, teamwork, and work-life balance. Teacher identity, student interest in a surgical career, student perception of the HF curriculum, and teaching awards. Ninety-two of 123 faculty and residents in a single program (75% of total) completed a survey on teacher identity. Fifteen of the participants were teachers of HF. Teachers of HF scored higher than control participants on the total score for teacher identity (P teach (P = .008), receiving rewards (P =.01), and HF (P = .02). Third-year clerks indicated that they were more likely to select surgery as their career after the clerkship and rated the curriculum higher when it was taught by surgeons than when taught by educators. Of the teaching awards presented to surgeons during HF years, 100% of those awarded to attending physicians and 80% of those awarded to residents went to teachers of HF. Curricular focus on HF can strengthen teacher identity, improve teacher evaluations, and promote surgery as a career choice.

Burnout is a major concern in human service occupations, mainly characterizing in emotional exhaustion and depersonalization. There is very limited research dealing with burnout in orthopedic surgeons. Exploring burnout prevalence, risk factors, and intraoperative irritability-related incidences is necessary to improve the quality of life for surgeons. The study population consisted of 202 registered adult reconstructive doctors in China. Burnout was measured using a normalized translated version of the Maslach Burnout Inventory-Human Service Survey. Demographics, professional characteristics, and intraoperative irritability-related questions were also collected by electronic questionnaires. Statistical analysis was performed using SPSS 22.0. The overall rate of burnout was 85.1%. Variables significantly associated with high emotional exhaustion scores included poor sleeping time per day (P = .008), more nights on call per week (P = .048), and absence of research (P = .014). For depersonalization, absence of marriage (P burnout, especially in emotional exhaustion. Residents were the population having the least opportunities to lose temper in operation. Burnout is highly prevalent in Chinese adult reconstructive surgeons, and it had some correlations with irritability. Further research is needed to determine more risk factors and reduce intraoperative irritability-related incidences. Copyright © 2017 Elsevier Inc. All rights reserved.

Anterior abdominal wall hernias are among the most commonly encountered surgical disease. We sought to identify risk factors that are associated with 30-day postoperative mortality following emergent abdominal wall hernia repair using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. A retrospective analysis of data from the ACS NSQIP from 2005 to 2010 was performed. Patients were selected using Current Procedural Terminology (CPT) and International Classification of Disease 9 Clinical Modification (ICD9) codes for the repair of inguinal, femoral, umbilical, epigastric, ventral, or incisional hernias that were incarcerated, obstructed, strangulated, or gangrenous. Only emergent cases occurring within two days of admission and admitted as inpatients were included. Univariate and multivariable analysis was performed. A risk score was also created. There were 4298 cases of emergent anterior abdominal wall hernia surgery. The most common was inguinal (25.3 %), followed by incisional (23.8 %), umbilical (23.5 %), ventral (12.1 %), femoral (8.8 %), and epigastric (6.5 %) hernias. Multivariable analysis demonstrated six statistically significant predictors of short-term mortality, including history of congestive heart failure (CHF) [odds ratio (OR) 8.24, 95 % confidence interval (CI) 4.05-16.75), age (OR 5.52, 95 % CI 3.48-8.77), history of peripheral vascular disease (PVD) (OR 4.98, 95 % CI 2.08-11.92), presence of ascites (OR 3.16, 95 % CI 1.64-6.08), preoperative blood urea nitrogen (OR 1.35, 95 % CI 1.22-1.49), and preoperative white blood cell count (OR 1.22, 95 % CI 1.02-1.45). The C-statistic for the risk model was 0.858. We present a large study on short-term mortality following emergent anterior abdominal wall hernia repairs based on the ACS NSQIP with a derived risk model that demonstrates excellent discriminative ability.

Obesity is a risk factor for cholelithiasis leading to acute cholecystitis which is treated with cholecystectomy. The purpose of this study was to analyze the associations between body mass index class and the intended operative approach (laparoscopic versus open) for and outcomes of cholecystectomy for acute cholecystitis. We conducted a retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program data from 2008-2013. The effects of body mass index class on intended procedure type (laparoscopic versus open), conversion from laparoscopic to open operation, and outcomes after cholecystectomy were examined using multivariable logistic regression. Data on 20,979 patients who underwent cholecystectomy for acute cholecystitis showed that 18,228 (87%) had a laparoscopic operation; 639 (4%) of these patients required conversion to an open approach; and 2,751 (13%) underwent intended open cholecystectomy. There was an independent association between super obesity (body mass index 50+) and an intended open operation (odds ratio 1.53, 95% confidence interval 1.14-2.05, P = .01). An intended open procedure (odds ratio 3.10, 95% confidence interval 2.40-4.02, P cholecystitis, not body mass index class, is associated with worse outcomes after cholecystectomy. An initial attempt at laparoscopy may benefit patients, even those at the highest end of the body mass index spectrum. Copyright © 2016 Elsevier Inc. All rights reserved.

Early introduction of a full-day human factors training experience into the surgical clerkship curriculum will teach effective communication skills and strategies to gain professional satisfaction from a career in surgery. In pilot 1, which took place between July 1, 2007, and December 31, 2008, 50 students received training and 50 did not; all received testing at the end of the rotation for comparison of control vs intervention group performance. In pilot 2, a total of 50 students were trained and received testing before and after rotation to examine individual change over time. University of Massachusetts Medical School. A total of 148 third-year medical students in required 12-week surgical clerkship rotations. Full-day training with lecture and small-group exercises, cotaught by surgeons and educators, with focus on empathetic communication, time management, and teamwork skills. Empathetic communication skill, teamwork, and patient safety attitudes and self-reported use of time management strategies. Empathy scores were not higher for trained vs untrained groups in pilot 1 but improved from 2.32 to 3.45 on a 5-point scale (P Students also were more likely to ask for the nurse's perspective and to seek agreement on an action plan after team communication training (pilot 1, f = 7.52, P = .007; pilot 2, t = 2.65, P = .01). Results were mixed for work-life balance, with some trained groups scoring significantly lower than untrained groups in pilot 1 and no significant improvement shown in pilot 2. The significant increase in student-patient communication scores suggests that a brief focused presentation followed by simulation of difficult patient encounters can be successful. A video demonstration can improve interdisciplinary teamwork.
Full Text Available Peritoneal dialysis is an established form of renal replacement therapy used in many patients with end-stage renal disease. The key to a successful chronic peritoneal dialysis is a permanent and safe access to the peritoneal cavity. This study was conducted in order to evaluate the catheter survival and its related factors in Imam Khomeini Hospital. A total of 80 catheters were inserted into 69 patients (52 men and 28 women with end-stage chronic renal failure during a period of 84 months. Retrospectively the correlation between catheter survival (overall and event free with demographic factors (sex and age, surgical factors (surgeons and surgical methods, nephrologic factors (the causes of peritoneal dialysis selection and the history of hemodialysis and peritonitis factors (the history and number of peritonitis has been evaluated. The mean age of the patients was 48.35 years (16 to 79 years. The overall survival of catheters or the probability of having a functioning catheter after one, two and three years was 53%, 41%, 22%, respectively. The event free survival of the catheter or the probability of having a functioning catheter without any problems after one year was 14%. It has been found out that among all factors in this study only history of hemodialysis had statistically significant effect on the overall survival of continuous ambulatory peritoneal dialysis catheter (P = 0.04. It seems that the overall survival of catheters is better when CAPD is started before any other attempts for hemodialysis.

Up to 2.3 million people are colonized with methicillin-resistant Staphylococcus aureus in the United States, causing well-documented morbidity and mortality. Although the association of clinical outcomes with community and hospital carriage rates is increasingly defined, less is reported about asymptomatic colonization prevalence among physicians, and specifically plastic surgeons and the subsequent association with the incidence of patient surgical-site infection. A review of the literature using the PubMed and Cochrane databases analyzing provider screening, transmission, and prevalence was undertaken. In addition, a search was completed for current screening and decontamination guidelines and outcomes. The methicillin-resistant S. aureus carriage prevalence of surgical staff is 4.5 percent. No prospective data exist regarding transmission and interventions for plastic surgeons. No studies were found specifically looking at prevalence or treatment of plastic surgeons. Current recommendations by national organizations focus on patient-oriented point-of-care testing and intervention, largely ignoring the role of the health care provider. Excellent guidelines exist regarding screening, transmission prevention, and treatment both in the workplace and in the community. No current such guidelines exist for plastic surgeons. No Level I or II evidence was found regarding physician screening, treatment, or transmission. Current expert opinion, however, indicates that plastic surgeons and their staff should be vigilant for methicillin-resistant S. aureus transmission, and once a sentinel cluster of skin and soft-tissue infections is identified, systematic screening and decontamination should be considered. If positive, topical decolonization therapy should be offered. In refractory cases, oral antibiotic therapy may be required, but this should not be used as a first-line strategy.

The aim of this study is to analyze the clinical and surgical features of patients who underwent robotic-assisted radical prostatectomy (RARP) at our institution, and the impact of the surgeon's experience in the oncological results related to pathological stage. An analysis of 300 RARP consecutively performed by the same urologist was conducted. Patients were divided into 3 groups of 100 patients in chronological order, according to surgery date. All patients had organ-confined clinical stage. Variables which could impact in positive margins rates were analyzed. Finally, positive surgical margins (PSM) in regard to pathological stage and surgeon's experience were compared and analyzed. No significant differences were found in variables which could impact in PSM rates. The overall PSM rate was 21%, with 28% in the first group, 20% in the second, and 16% in the third (P = .108). Significant lineal decreasing tendency was observed (P = .024). In pT2 patients, the overall PSM rate was 16.6%, with 27%, 13.8%, and 7.3% in each group respectively (P = .009). A significant difference was found between group 1 and group 3 (P = .004). In pT3 patients, the surgeon's experience was not significantly associated with margin reductions with an overall PSM rate of 27.7% (28.2%, 28.6%, and 26.7% in each group respectively). Clinical and surgical features in our patients did not vary over time. We found a significant reduction of PSM related to surgeon's experience in pT2 patients. Contrariwise, the margin status remained stable despite increasing experience in pT3 patients. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

As North Atlantic Treaty Organization (NATO) countries begin troop withdrawal from Afghanistan, military medicine needs programs for combat surgeons to retain the required knowledge and surgical skills. Each military branch runs programs at various Level I academic trauma centers to deliver predeployment training and provide a robust trauma experience for deploying surgeons. Outside of these successful programs, there is no system-wide mechanism for nondeploying military surgeons to care for a high volume of critically ill trauma patients on a regular basis in an educational environment that promotes continued professional development. We hypothesize that fully integrated military-civilian relationship regional Level I trauma centers provide a surgical experience more closely mirroring that seen in a Role III hospital than local Level II and Level III trauma center or medical treatment facilities. We characterized the Level I trauma center practice using the number of trauma resuscitations, operative trauma/acute care surgery procedures, number of work shifts, operative density (defined as the ratio of operative procedures/days worked), and frequency of educational conferences. The same parameters were collected from two NATO Role III hospitals in Afghanistan during the peak of Operation Enduring Freedom. Data for two civilian Level II trauma centers, two civilian Level III trauma centers, and a Continental United States Military Treatment Facility without trauma designation were collected. The number of trauma resuscitations, number of 24-hour shifts, operative density, and educational conferences are shown in the table for the Level I trauma center compared with the different institutions. Civilian center trauma resuscitations and operative density were highest at the Level I trauma center and were only slightly lower than what was seen in Afghanistan. Level II and III trauma centers had lower numbers for both. The Level I trauma center provided the most frequent

Guided imagery and music can reportedly reduce pain and anxiety during surgery, but no comparative study has been performed for cutaneous surgery to our knowledge. We sought to determine whether short-contact recorded guided imagery or relaxing music could reduce patient pain and anxiety, and surgeon anxiety, during cutaneous surgical procedures. Subjects were adults undergoing excisional surgery for basal and squamous cell carcinoma. Randomization was to guided imagery (n = 50), relaxing music (n = 54), or control group (n = 51). Primary outcomes were pain and anxiety measured using visual analog scale and 6-item short-form of the State-Trait Anxiety Inventory, respectively. Secondary outcomes were anxiety of surgeons measured by the 6-item short-form of the State-Trait Anxiety Inventory and physical stress of patients conveyed by vital signs, respectively. There were no significant differences in subjects' pain, anxiety, blood pressure, and pulse rate across groups. In the recorded guided imagery and the relaxing music group, surgeon anxiety was significantly lower than in the control group. Patients could not be blinded. Short-contact recorded guided imagery and relaxing music appear not to reduce patient pain and anxiety during excisional procedures under local anesthetic. However, surgeon anxiety may be reduced when patients are listening to such recordings. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

In the third molar surgery, it is important to focus not only on surgical skills, but also on patient satisfaction. Classically studies have been focused on surgery and surgeon's empathy, but there are non-surgical factors that may influence patient satisfaction. A cross-sectional study was performed on 100 patients undergoing surgical extractions of impacted mandibular third molars treated from October 2013 to July 2014 in the Oral Surgery Unit of the University of Valencia. A questionnaire (20 questions) with a 10-point Likert scale was provided. The questionnaire assessed the ease to find the center, the ease to get oriented within the center, the burocratic procedures, the time from the first visit to the date of surgical intervention, waiting time in the waiting room, the comfort at the waiting room, the administrative staff (kindness and efficiency to solve formalities), medical staff (kindness, efficiency, reliability, dedication), personal data care, clarity in the information received (about the surgery, postoperative care and resolution of the doubts), available means and state of facilities. Outcome variables were overall satisfaction and recommendation of the center. Statistical analysis was made using the multiple linear regression analysis. Significant correlations were found between all variables and overall satisfaction. The multiple regression model showed that the efficiency of the surgeon and the clarity of the information were statistically significant to overall satisfaction and recommendation of the center. The kindness of the administrative staff, available means, the state of facilities and the comfort at the waiting room were statistically significant to the recommendation of the center. Patient satisfaction directly depends on the efficiency of the surgeon and clarity of the clinical information received about the procedure. Appreciation of these predictive factors may help clinicians to provide optimal care for impacted third molar

A key metric of the research quality of medical conferences is the publication rate of abstracts. The study objective was to determine the publication rate of abstracts presented at the Royal Australasian College of Surgeons Annual Scientific Congress (RACS ASC) and to examine for any predictive factors associated with publication. Abstracts presented at the RACS ASC from 2011 to 2013 were analysed. Abstract characteristics such as presentation format, study type, study design, study site, cohort size and author origin were recorded. Abstracts published were identified by a PubMed search using a strict algorithm. Univariate and multivariable logistic regressions were used to analyse for predictive factors of publication. Overall, 1438 abstracts were presented and 423 abstracts (29%) were published. The median time to publication was 15.2 months (interquartile range: 8-26) with 110 in Australasian journals (26%). The median number of citations for published abstracts was 6 (interquartile range: 2-16). After multivariable analysis, publication was significantly associated with prospective study design (odds ratio (OR) = 1.34, P = 0.02), multicentre study site (OR = 1.43, P = 0.02), cohort size ≥100 (OR = 2.00, P Australasian College of Surgeons.

Ankle fracture is a common injury and there is an increasingly greater emphasis on operative fixation. The purpose of the study was to determine the complication rate in this cohort of patients and, in doing so, determine risk factors which predispose to surgical site infection. A prospective cohort study was performed at a tertiary referral trauma center examining risk factors for surgical site infection in operatively treated ankle fractures. Univariate and multivariate analysis was performed. Female gender and advancing age were determined to be the risk factors in univariate analysis. Drain usage and peri-operative pyrexia were found to be significant for infection in multivariate analysis. This study allows surgeons to identify those at increased risk of infection and counsel them appropriately. It also allows for a high level of vigilance with regard to soft tissue handling intra-operatively in this higher risk group.

The purpose of this study was to evaluate mid-term results of proximal femoral varus derotation osteotomy (VDRO) in children with cerebral palsy and determine what effect age, Gross Motor Function Classification System (GMFCS) level, and surgeon volume had on surgical success. We analyzed a cohort of children with cerebral palsy who underwent VDRO for hip displacement at a tertiary-level pediatric hospital between 1994 and 2007. Age, sex, GMFCS level, preoperative radiographic parameters, previous botulinum toxin administration or soft-tissue release, adjunctive pelvic osteotomy, the performance of bilateral surgery at the index VDRO, and surgeon volume (the number of procedures performed) were recorded. Results were analyzed via univariate and multivariate analyses for association with the need for revision hip surgery. Kaplan-Meier survivorship curves were generated, determining the time from index surgery to failure (defined as the need for subsequent surgical procedures on the hip and/or pelvis, or a hip migration percentage of >50% at the time of final follow-up), and were further stratified according to osseous versus soft-tissue revision. A total of 567 VDROs were performed in 320 children (mean age [and standard deviation], 8.2 ± 3.8 years). The mean follow-up was 8.3 years (range, three to eighteen years). Of the initial 320 patients, 117 (37%) were considered to have had failure. Multivariate Cox regression analysis confirmed that younger age at surgery (p cerebral palsy. Older age, lower GMFCS level, and increased surgeon volume were strong predictors of surgical success. Copyright © 2015 by The Journal of Bone and Joint Surgery, Incorporated.

The objective of our study was to analyze plenary abstracts since 2006, when the Association for Academic Surgery (AAS) and Society of University Surgeons (SUS) began hosting the combined annual Academic Surgical Congress (ASC). Plenary session abstracts from the separate AAS and SUS meetings from 2002 to 2004 had previously revealed no significant difference in the scientific impact of published manuscripts. In total, 76 abstracts from the AAS (n = 40) and SUS (n = 36) plenary sessions at the annual ASC meetings (2006-2010) were reviewed. Publication rate, citation number, 2010 impact factor (IF), and 5-y IF were obtained. Statistical analysis was conducted using Fisher exact and Student t-tests. Overall, 60 (79%) of 76 ASC plenary abstracts presented between 2006 and 2010 were published in peer-reviewed journals. Analysis revealed a higher publication rate for AAS (90%) compared with SUS (67%) plenary abstracts (P = 0.02). Among the articles published, the overall mean number of total citations was 6.7, with no difference between AAS and SUS (5.9 versus 7.8, P = 0.46). The mean 2010 five-year IF for all publications was 4.6 (AAS, 4.3 versus SUS, 5.0; P = 0.54). Compared with a previous analysis from the separate meetings, the mean IF has increased for both societies at an equivalent rate of 0.4. After the initiation of the joint ASC meeting in 2006, the SUS and AAS plenary presentations continue to exhibit high-quality research. This study supports the benefit of a joint meeting for the AAS and SUS, as it has been associated with an increasing overall scientific impact for plenary abstracts. Copyright © 2013 Elsevier Inc.

To assess the working styles of men and women working as surgeons in Japan. In July, 2014, the Japan Surgical Society invited all their members (n = 29,861), through an internet campaign, to participate in a nationwide survey of surgeons. The items investigated in this descriptive study included demographic information and working styles, based on a questionnaire. In total, 6211 surgeons participated (response rate 20.8%, 5586 men and 625 women). The largest age stratum was 40-49 years for men and 30-39 years for women. Overall, respondents identified their labor contract, including salary and work hours, as the highest priority for improvement. Women with children were more likely to be part-time employees, work fewer hours, and take fewer house calls/on-calls than their male counterparts. Moreover, women of all ages earned a lower annual income than men, irrespective of whether they had children. Perception scores for discrimination related to work and promotion were significantly higher among women than men (p Japan.

Although imaging has a major role in evaluation and management of thoracolumbar spinal trauma by spine surgeons, the exact role of computed tomography (CT) and magnetic resonance imaging (MRI) in addition to radiographs for fracture classification and surgical decision-making is unclear. Spine surgeons (n = 41) from around the world classified 30 thoracolumbar fractures. The cases were presented in a three-step approach: first plain radiographs, followed by CT and MRI images. Surgeons were asked to classify according to the AOSpine classification system and choose management in each of the three steps. Surgeons correctly classified 43.4 % of fractures with plain radiographs alone; after, additionally, evaluating CT and MRI images, this percentage increased by further 18.2 and 2.2 %, respectively. AO type A fractures were identified in 51.7 % of fractures with radiographs, while the number of type B fractures increased after CT and MRI. The number of type C fractures diagnosed was constant across the three steps. Agreement between radiographs and CT was fair for A-type (k = 0.31), poor for B-type (k = 0.19), but it was excellent between CT and MRI (k > 0.87). CT and MRI had similar sensitivity in identifying fracture subtypes except that MRI had a higher sensitivity (56.5 %) for B2 fractures (p change after an MRI (p = 0.77). For accurate classification, radiographs alone were insufficient except for C-type injuries. CT is mandatory for accurately classifying thoracolumbar fractures. Though MRI did confer a modest gain in sensitivity in B2 injuries, the study does not support the need for routine MRI in patients for classification, assessing instability or need for surgery.

Surgical wound classification (SWC) is used for risk stratification of surgical site infection (SSI) and serves as the basis for measuring quality of care. The objective was to examine the accuracy and reliability of SWC. This study was purposed to evaluate the discrepancies in SWC as assessed by three groups: surgeons, an infection control nurse, and histopathologic evaluation. The secondary aim was to compare the risk-stratified SSI rates using the different SWC methods for 30 d postoperatively. An analysis was performed of the appendectomies from January 2013 to June 2014 in the Cantonal Hospital of Schaffhausen. SWC was assigned by the operating surgeon at the end of the procedure and retrospectively reviewed by a Swissnoso-trained infection control nurse after reading the operative and pathology report. The level of agreement among the three different SWC assessment groups was determined using kappa statistic. SSI rates were analyzed using a chi-square test. In 246 evaluated cases, the kappa scores for interrater reliability among the SWC assessments across the three groups ranged from 0.05 to 0.2 signifying slight agreement between the groups. SSIs were more frequently associated with trained infection control nurse-assigned SWC than with surgeons based SWC. Our study demonstrated a considerable discordance in the SWC assessments performed by the three groups. Unfortunately, the currently practiced SWC system suffers from ambiguity in definition and/or implementation of these definitions is not clearly stated. This lack of reliability is problematic and may lead to inappropriate comparisons within and between hospitals and surgeons. Copyright © 2017 The Author(s). Published by Elsevier Inc.

The objective of this study is the total evaluation of most common clinical factors influencing the successful rate of adenotonsillectomy for pediatric obstructive sleep apnea syndrome (OSAS). Retrospectively, 63 pediatric patients ranged from 2 to 16 years old were included. Syndromics and patients who had received orthodontic treatment or orthognathic surgery were excluded. All patients received pre-operative and postoperative polysomnography and cephalometry. Each patient received adenotonsillectomy by single surgeon. Surgical success was defined as apneahypopnea index (AHI) decreased ≧50 % or post-operative AHI cephalometry parameters. Mean age of the total 63 patients was 7.78 years old. Mean BMI of the patients was 19.02. The proportion of obese patients was 25.4% (16/63). Surgical success was achieved in 42 out of 63 patients (66.7%). The surgical success was not statistically significant related to all pre-operative cephalometric parameters, age, gender, BMI and adenoid size by multiple logistic regression model. However, the surgical success was significantly related to pre-operative AHI and tonsil size. In addition, all patients who received adenotonsillectomy showed improved polysomnography parameters, including AHI, AI, HI, mean O 2 saturation and nadir O 2 saturation which all reached statistically significant improvement. Although adenotonsillectomy cannot cure pediatric OSAS in our research, all patients showed significant improvement of polysomnography parameters after this procedure. Pre-operative cephalometry parameters, BMI and age did not show significant correlation with surgical success, however, pre-op AHI and tonsil size correlated with surgical success. Higher pre-op AHI value and higher tonsil grade showed higher rate of surgical success. Based on the total evaluation of clinical data, surgical success after adenotonsillectomy might be predicted by pre-op AHI severity and tonsil grade.

We have investigated how surgeons can use the foot to position a laparoscopic endoscope, a task that normally requires an extra assistant. Surgeons need to train in order to exploit the possibilities offered by this new technique and safely manipulate the endoscope together with the hands movements. A realistic abdominal cavity has been developed as training simulator to investigate this multi-arm manipulation. In this virtual environment, the surgeon's biological hands are modelled as laparoscopic graspers while the viewpoint is controlled by the dominant foot. 23 surgeons and medical students performed single-handed and bimanual manipulation in this environment. The results show that residents had superior performance compared to both medical students and more experienced surgeons, suggesting that residency is an ideal period for this training. Performing the single-handed task improves the performance in the bimanual task, whereas the converse was not true.

Surgical site infections are one of the more common major complications of elbow fracture surgery and can contribute to other adverse outcomes, prolonged hospital stays, and increased healthcare costs. We asked: (1) What are the factors associated with a surgical site infection after elbow fracture surgery? (2) When taking the subset of closed elbow fractures only, what are the factors associated with a surgical site infection? (3) What are the common organisms isolated from an elbow infection after open treatment? One thousand three hundred twenty adult patients underwent surgery for an elbow fracture between January 2002 and July 2014 and were included in our study. Forty-eight of 1320 patients (4%) had a surgical site infection develop. Thirty-four of 1113 patients with a closed fracture (3%) had a surgical site infection develop. For all elbow fractures, use of plate and screw fixation (adjusted odds ratio [OR]= 2.2; 95% CI, 1.0-4.5; p = 0.041) and use of external fixation before surgery (adjusted OR = 4.7; 95% CI, 1.1-21; p = 0.035) were associated with higher infection rates. When subset analysis was performed for closed fractures, only smoking (adjusted OR = 2.2; 95% CI, 1.1-4.5; p = 0.023) was associated with higher infection rates. Staphylococcus aureus was the most common bacteria cultured (59%). The only modifiable risk factor for a surgical site infection after open reduction and internal fixation was cigarette smoking. Plate fixation and temporary external fixation are likely surrogates for more complex injuries, therefore no recommendations should be inferred from this association. Surgeons should counsel patients who smoke. Level IV, prognostic study.

Owing to the phenomenon known as "global graying," elderly-specific conditions, including frailty, will become more prominent among patients undergoing surgery. The concept of frailty, its effect on surgical outcomes, and its assessment and management were discussed during the 38th Annual Surgical Symposium of the Association of VA Surgeons panel session entitled "What's the Big Deal about Frailty?" and held in New Haven, Connecticut, on April 7, 2014. The expert panel discussed the following questions and topics: (1) Why is frailty so important? (2) How do we identify the frail patient prior to the operating room? (3) The current state of the art: preoperative frail evaluation. (4) Preoperative interventions for frailty prior to operation: do they work? (5) Intraoperative management of the frail patient: does anesthesia play a role? (6) Postoperative care of the frail patient: is rescue the issue? This special communication summarizes the panel session topics and provides highlights of the expert panel's discussions and relevant key points regarding care for the geriatric frail surgical patient.

There is a growing concern for microbial resistance as a result of overuse of antibiotics. Although guidelines have focused on the use of antibiotics for surgery in general, few have addressed plastic surgery specifically. The objective of this expert consensus conference was to evaluate the evidence for efficacy and safety of antibiotic prophylaxis in plastic surgical procedures. THE AUTHORS: searched for existing high-quality systematic reviews for antibiotic prophylaxis in the literature from the MEDLINE, Cochrane Library, and Embase databases. All synonyms for antibiotics were combined with terms for relevant plastic surgery procedures. The searches were not limited by language, and included all study designs. In addition, supplemental hand searches were performed of bibliographies of relevant articles, and extensive "related articles." Meta-analyses were performed and reviewed by experts selected by the American Association of Plastic Surgeons to reach consensus recommendations. Database searches identified 4300 articles, from which 2042 full-text articles were identified for eligibility. De novo meta-analyses were performed for each plastic surgical category. In total, 67 studies met the inclusion criteria, including nine for breast surgery, 17 for head and neck surgery, 10 for orthognathic surgery, seven for rhinoplasty/septoplasty, 19 for hand surgery, five for skin surgery, and two for abdominoplasty. Systemic antibiotic prophylaxis is recommended for clean breast surgery and for contaminated surgery of the hand or the head and neck. It is not recommended to reduce infection in clean surgical cases of the hand, skin, head and neck, or abdominoplasty.

Gross hip instability is a rare complication after hip arthroscopy, and there is limited literature surrounding this topic. This systematic review investigates cases of gross hip instability after arthroscopy and discusses the risk factors associated with this complication. A systematic search was performed in duplicate for studies investigating gross hip instability after hip arthroscopy up to October 2015. Study parameters including sample size, mechanism and type of dislocation, surgical procedure details, patient characteristics, postoperative rehabilitation protocol, and level of evidence were analyzed. The systematic review identified 9 case reports investigating gross hip instability after hip arthroscopy (10 patients). Anterior dislocation occurred in 66.7% of patients, and most injuries occurred with a low-energy mechanism. Common surgical factors cited included unrepaired capsulotomy (77.8%) and iliopsoas release (33.3%), whereas patient factors included female gender (77.8%), acetabular dysplasia (22.2%), and general ligamentous laxity (11.1%). Postoperative restrictions and protocols were variable and inconsistently reported, and their relation to post-arthroscopy instability was difficult to ascertain. This systematic review discussed various patient, surgical, and postoperative risk factors of gross hip instability after arthroscopy. Patient characteristics such as female gender, hip dysplasia, and ligamentous laxity may be risk factors for post-arthroscopy dislocation. Similarly, surgical risk factors for iatrogenic hip instability may include unrepaired capsulotomies and iliopsoas debridement, although the role of capsular closure in iatrogenic instability is not clear. The influences of postoperative restrictions and protocols on dislocation are also unclear in the current literature. Surgeons should be cognizant of these risk factors when performing hip arthroscopy and be mindful that these factors appear to occur in combination. Level IV

To discover the level of interest in a surgical career amongst junior doctors and trainee interns in the Auckland region. Secondary aims are to identify the factors that influence career choice as well as the timing of career choice. An anonymous and structured questionnaire was distributed to all trainee interns and junior doctors in their first to fifth postgraduate years in the Auckland region. Questions were based on basic demographics, level of training, career preference and factors from previous experiences in surgery that may have influenced their career choice. Total of 87 replies with 36% expressed interest in surgery whereas 64% were interested in non-surgical specialties. Top three factors influencing career choice were similar in both groups: Lifestyle, career ambitions and family. Personal interest, practical hands-on and positive previous experiences were the top reasons why junior doctors chose surgery. Poor lifestyle, lacking of interest, limited future part-time work and previous negative experiences were the top reasons why junior doctors did not choose surgery. A significantly (pcareers earlier. Career aspirations of New Zealand junior doctors were similar to findings reported overseas. To promote surgery amongst junior doctors and medical students, attention should be paid to the key factors which may influence career choice. By improving working conditions and have better surgical education with good mentoring, team atmosphere and opportunities for early exposure will hopefully allow better recruitment and training of future surgeons.

Knowledge of hospital-specific average cesarean delivery operative times, and factors influencing length of surgery, can serve as a guide for anesthesiologists when choosing the optimal anesthetic technique. The aim of this study was to determine operative times and the factors influencing those times for cesarean delivery. We conducted a retrospective review of all 1348 cesarean deliveries performed at an academic hospital in 2011. The primary outcome was mean operative time for first, second, third and fourth or more cesarean deliveries. The secondary goal was to identify factors influencing operative time. Variables included age, body mass index, previous surgery, gestational age, urgency of cesarean delivery, anesthesia type, surgeon's seniority, layers closed, and performance of tubal ligation. Mean (standard deviation) operative times for first (n=857), second (n=353), third (n=108) and fourth or more (n=30) cesarean deliveries were 56 (19), 60 (19), 69 (28) and 82 (31) minutes, respectively (P cesarean delivery or the presence of other factors that could increase operative time may warrant catheter-based anesthetic techniques or the addition of adjunctive medications to prolong spinal anesthetic block. Institutional and individual surgeon factors may play an even more important role in determining surgical time. Copyright © 2018 Elsevier Ltd. All rights reserved.

CDH patients experience multi-system morbidity. Despite apparent health, late childhood complications do occur. We reviewed the long-term surgical morbidity of our CDH patients to determine whether protracted clinical surveillance is warranted. A single-institution retrospective chart review of all CDH survivors treated from 1999 to 2011 who are followed at our CDH multidisciplinary clinic was performed. Descriptive and statistical analyses were performed to show risk of surgical complications over time. A total of 187 CDH patients were treated with 160 surviving to discharge (86%). Primary repair was performed in 115 (73%), and 42 (27%) underwent patch repair. CDH recurrence occurred in 23 (15%) at a median time of 0.7 (range 0-8.5) years (65% asymptomatic). Seventy percent of recurrences occurred before 2 years and 17% after 4 years. Bowel obstruction occurred in 12 (8%) at a median time of 0.7 (range 0.2-7.2) years post-repair, and chest deformity occurred in 13 (8%) at a median of 5 (range 1.1-6.8) years. For patch repairs, scoliosis occurred in 4 (10%) patients at a median age of 3 (range 0.6-5) years. Surgical complications in CDH survivors are common, can occur many years later, and are frequently asymptomatic. Long-term surveillance of CDH patients is recommended for early identification and treatment of complications. Copyright © 2013 Elsevier Inc. All rights reserved.

Oral cancer results in significant morbidity and mortality in those afflicted. Despite modern treatments, mortality is high, with overall 5-year survival rates that approximate 50%. However, early stage disease (Stages 1 and 2) carries a significantly better prognosis than late stage disease (Stages 3 and 4), therefore, prevention and early detection continue to be important in improving oral cancer control. The role of dental care providers in routine oral cancer screenings, smoking cessation, treatment, and rehabilitation of oral cancer patients is emphasized in this article. This article also discusses the epidemiology, etiology, diagnosis, and treatment of oral cancer and the role of oral and maxillofacial surgeons in the surgical and medical management of oral cancer patients in the United States.

Timor-Leste suffered a destructive withdrawal by the Indonesian military in 1999, leaving only 20 Timorese-based doctors and no practising specialists for a population of 700 000 that has now grown to 1.2 million. This article assesses the outcomes and impact of Royal Australasian College of Surgeons (RACS) specialist medical support from 2001 to 2015. Three programmes were designed collaboratively with the Timor-Leste Ministry of Health and Australian Aid. The RACS team began to provide 24/7 resident surgical and anaesthesia services in the capital, Dili, from July 2001. The arrival of the Chinese and Cuban Medical Teams provided a medical workforce, and the Cubans initiated undergraduate medical training for about 1000 nationals both in Cuba and in Timor-Leste, whilst RACS focused on specialist medical training. Australian Aid provided AUD$20 million through three continuous programmes over 15 years. In the first 10 years over 10 000 operations were performed. Initially only 10% of operations were done by trainees but this reached 77% by 2010. Twenty-one nurse anaesthetists were trained in-country, sufficient to cover the needs of each hospital. Seven Timorese doctors gained specialist qualifications (five surgery, one ophthalmology and one anaesthesia) from regional medical schools in Papua New Guinea, Fiji, Indonesia and Malaysia. They introduced local specialist and family medicine diploma programmes for the Cuban graduates. Timor-Leste has developed increasing levels of surgical and anaesthetic self-sufficiency through multi-level collaboration between the Ministry of Health, Universidade Nacional de Timor Lorosa'e, and sustained, consistent support from external donors including Australian Aid, Cuba and RACS. © 2016 Royal Australasian College of Surgeons.

Full Text Available Background and Objectives: Surgical site infection (SSI is the most common nosocomial infection encountered in post operative surgical wards. The use of prophylactic antibiotic in clean elective surgical cases is still a subject of controversy to surgeons. The objective of the study is to identify the need for using prophylactic antibiotics in clean surgeries, prevalence of organisms in patients who are not given prophylactic antibiotics and to study whether the presence of risk factors increase the incidence of surgical site infection. Methodology: The comparative study consists of 100 cases admitted under two groups of 50 each: Group A was given prophylactic antibiotic and Group B didn’t receive any. All surgeries other than clean surgical cases were excluded from the study. Results: Out of 50 patients in group B who were not given prophylactic antibiotic, 2 patients had more than one risk factor for development of SSI and both of them developed SSI. Of the 50 patients who received prophylactic antibiotic, none developed SSI. The rate of infection in group A was nil and in Group B was 4%. Conclusion: Prophylactic antibiotics are not recommended for clean elective surgical cases as there is no statistically significant change in the infection rate seen in patients not receiving prophylactic antibiotic(P=0.4952. Meticulous surgical technique and correcting risk factors prior to surgery is a must for reducing incidence of SSI.

The risk factors for surgical site infections in surgery should be measured and monitored from admission to 30 days after the surgical procedure, because 30% of Surgical Site Infection is detected when the patient was discharged. Calculate the Relative Risk of associated factors to surgical site infections in adult with elective surgery. Patients were classified according to the surgery contamination degree; patient with surgery clean was defined as no exposed and patient with clean-contaminated or contaminated surgery was defined exposed. Risk factors for infection were classified as: inherent to the patient, pre-operative, intra-operative and post-operative. Statistical analysis; we realized Student t or Mann-Whitney U, chi square for Relative Risk (RR) and multivariate analysis by Cox proportional hazards. Were monitored up to 30 days after surgery 403 patients (59.8% women), 35 (8.7%) developed surgical site infections. The factors associated in multivariate analysis were: smoking, RR of 3.21, underweight 3.4 hand washing unsuitable techniques 4.61, transfusion during the procedure 3.22, contaminated surgery 60, and intensive care stay 8 to 14 days 11.64, permanence of 1 to 3 days 2.4 and use of catheter 1 to 3 days 2.27. To avoid all risk factors is almost impossible; therefore close monitoring of elective surgery patients can prevent infectious complications.

Abstract Background The techniques for the resection of renal tumors with IVC extension are based on the experience of individual units. We attempt to provide a logical approach of the surgical strategies in a stepwise fashion. Methods Over 6-years 9 patients with renal cell carcinoma invading the IVC, underwent surgery. There were 6 males. The extension was at level IV in 4 and III in 5 cases. CPB used in 8 and hypothermia and circulatory arrest in all patients with level IV disease. The results and an algorithm of the plan of action, as per level of extension are presented. Results Plan of action: For level I-II disease: No Cardiothoracic involvement, For level III: Cardiopulmonary Bypass (CPB) & control of the cavo-atrial junction. For level IV: use of brief periods of Circulatory Arrest & repair of the Cavotomy with a pericardial patch. Postoperative morbidity: prolonged ICU stay, 3 patients (33.3%); tracheostomy, 1 (11.1%); Sepsis, 2 (22.2%); CVA 1, (11.1%). Mortality: 2 patients (22.2%) Conclusions Total clearance of the IVC from an adherent tumor is important, therefore extensive level IV disease presents a surgical challenge. We recommend CPB for level III and brief periods of Total Circulatory Arrest (TCA) for level IV disease.

The goal of this study was to calculate total factor productivity of surgeons in an academic year and to evaluate the effect of surgical trainees on their productivity. We analyzed all the surgical procedures performed from April 1 through September 30, 2013 in the Teikyo University Hospital. The nonradial and nonoriented Malmquist model under the variable returns-to-scale assumptions was employed. A decision-making unit is defined as a surgeon with the highest academic rank in the surgery. Inputs were defined as the number of physicians who assisted in surgery, and the time of surgical operation from skin incision to skin closure. The output was defined as the surgical fee for each surgery. April is the beginning month of a new academic year in Japan, and we divided the study period into April to June and July to September 2013. We computed each surgeon's Malmquist index, efficiency change, and technical change. We analyzed 2789 surgical procedures that were performed by 105 surgeons. The Malmquist index of all surgeons was significantly greater than 1 (p = 0.0033). The technical change was significantly greater than 1 (p productive in the beginning months of a new academic year. The main factor of this productivity loss is considered to be surgical training. Copyright © 2014 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.
Full Text Available To analyze the learning curve for cancer control from an initial 250 cases (Group I and subsequent 250 cases (Group II of robotic-assisted laparoscopic radical prostatectomy (RALP performed by a single surgeon. Five hundred consecutive patients with clinically localized prostate cancer received RALP and were evaluated. Surgical parameters and perioperative complications were compared between the groups. Positive surgical margin (PSM and biochemical recurrence (BCR were assessed as cancer control outcomes. Patients in Group II had significantly more advanced prostate cancer than those in Group I (22.2% vs 14.2%, respectively, with Gleason score 8-10, P= 0.033; 12.8% vs 5.6%, respectively, with clinical stage T3, P= 0.017. The incidence of PSM in pT3 was decreased significantly from 49% in Group I to 32.6% in Group II. A meaningful trend was noted for a decreasing PSM rate with each consecutive group of 50 cases, including pT3 and high-risk patients. Neurovascular bundle (NVB preservation was significantly influenced by the PSM in high-risk patients (84.1% in the preservation group vs 43.9% in the nonpreservation group. The 3-year, 5-year, and 7-year BCR-free survival rates were 79.2%, 75.3%, and 70.2%, respectively. In conclusion, the incidence of PSM in pT3 was decreased significantly after 250 cases. There was a trend in the surgical learning curve for decreasing PSM with each group of 50 cases. NVB preservation during RALP for the high-risk group is not suggested due to increasing PSM.
Academic requirements for Certificate of Completion of Training in surgical training: Consensus recommendations from the Association of Surgeons in Training/National Research Collaborative Consensus Group.
Lee, Mathew J; Bhangu, A; Blencowe, Natalie S; Nepogodiev, D; Gokani, Vimal J; Harries, Rhiannon L; Akinfala, M; Ali, O; Allum, W; Bosanquet, D C; Boyce, K; Bradburn, M; Chapman, S J; Christopher, E; Coulter, I; Dean, B J F; Dickfos, M; El Boghdady, M; Elmasry, M; Fleming, S; Glasbey, J; Healy, C; Kasivisvanathan, V; Khan, K S; Kolias, A G; Lee, S M; Morton, D; O'Beirne, J; Sinclair, P; Sutton, P A
Surgical trainees are expected to demonstrate academic achievement in order to obtain their certificate of completion of training (CCT). These standards are set by the Joint Committee on Surgical Training (JCST) and specialty advisory committees (SAC). The standards are not equivalent across all surgical specialties and recognise different achievements as evidence. They do not recognise changes in models of research and focus on outcomes rather than process. The Association of Surgeons in Training (ASiT) and National Research Collaborative (NRC) set out to develop progressive, consistent and flexible evidence set for academic requirements at CCT. A modified-Delphi approach was used. An expert group consisting of representatives from the ASiT and the NRC undertook iterative review of a document proposing changes to requirements. This was circulated amongst wider stakeholders. After ten iterations, an open meeting was held to discuss these proposals. Voting on statements was performed using a 5-point Likert Scale. Each statement was voted on twice, with ≥80% of votes in agreement meaning the statement was approved. The results of this vote were used to propose core and optional academic requirements for CCT. Online discussion concluded after ten rounds. At the consensus meeting, statements were voted on by 25 delegates from across surgical specialties and training-grades. The group strongly favoured acquisition of 'Good Clinical Practice' training and research methodology training as CCT requirements. The group agreed that higher degrees, publications in any author position (including collaborative authorship), recruiting patients to a study or multicentre audit and presentation at a national or international meeting could be used as evidence for the purpose of CCT. The group agreed on two essential 'core' requirements (GCP and methodology training) and two of a menu of four 'additional' requirements (publication with any authorship position, presentation

To identify pre-operative risk factors for surgical delay of more than 2 days after admission in patients older than 65 years with a hip fracture. A prospective observational study was conducted on 180 hip fractures in patients older than 65 years of age admitted to our hospital from January 2015 to April 2016. The data recorded included, patient demographics, day of admission, pre-fracture comorbidities, mental state, level of mobility and physical function, type of fracture, antiaggregant and anticoagulant medication, pre-operative haemoglobin value, type of treatment, and surgical delay. The mean age of the patients was 83.7 years. The mean Charlson Index was 2.8. The pre-fracture baseline co-morbidities were equal or greater than 2 in 70% of cases. Mean timing of surgery was 3.1 days. At the time of admission, 122 (67.7%) patients were fit for surgery, of which 80 (44.4%) underwent surgery within 2 days. A Charlson index greater than 2, anticoagulant therapy, and admission on Thursday to Saturday, were independently associated with a surgical delay greater than 2 days. The rate of hip fracture patients undergoing surgery within 2 days is low. Risk factors associated to surgical delay are non-modifiable. However, their knowledge should allow the development of protocols that can reduce surgical delay in this group of patients. Copyright © 2017 SECOT. Publicado por Elsevier España, S.L.U.

The ACS/ASE Medical Student Simulation-Based Skills Curriculum was developed to standardize medical student training. This study aims to evaluate the feasibility and validity of implementing the basic airway curriculum. This single-center, prospective study of medical students participating in the basic airway module from 12/2014-3/2016 consisted of didactics, small-group practice, and testing in a simulated clinical scenario. Proficiency was determined by a checklist of skills (1-15), global score (1-5), and letter grade (NR-needs review, PS-proficient in simulation scenario, CP-proficient in clinical scenario). A proportion of students completed pre/post-test surveys regarding experience, satisfaction, comfort, and self-perceived proficiency. Over 16 months, 240 students were enrolled with 98% deemed proficient in a simulated or clinical scenario. Pre/post-test surveys (n = 126) indicated improvement in self-perceived proficiency by 99% of learners. All students felt moderately to very comfortable performing basic airway skills and 94% had moderate to considerable satisfaction after completing the module. The ACS/ASE Surgical Skills Curriculum is a feasible and effective way to teach medical students basic airway skills using simulation. Copyright © 2016 Elsevier Inc. All rights reserved.

Musculoskeletal injury confers an enormous burden of preventable disability and mortality in low- and moderate-income countries (LMICs). Appropriate orthopedic and trauma care services are lacking. Leading international health agencies emphasize the critical need to create and sustain research capacity in the developing world as a strategic factor in the establishment of functional, independent health systems. One aspect of building research capacity is partnership between developing and deve...
Full Text Available Purpose: To evaluate the factors influencing final visual outcome after surgical repair of open globe injuries. Materials and Methods: The study was carried out at a tertiary referral eye care center in Central India. In this retrospective study, case records of 669 patients with open globe injuries were analyzed. Different preoperative variables were correlated with the final visual outcome. Exclusion criteria were patients with less than four months follow up, previous ocular surgery, presence of intraocular foreign body or endophthalmitis at the time of presentation. Using statistical tests, the prognostic factors for vision outcome following surgical repair of open globe injuries were studied. Results: Based on the Spearman′s Rho correlation analysis, following factors were found to be significantly associated with the final visual acuity at univariate level: age (P<0.001, preoperative visual acuity (P=0.045, mode of injury (P=0.001, and time lag between the injury and surgery (P=0.003. None of the other clinical factors have statistically significant correlation with final visual acuity. On multivariate analysis using binary logistic regression, only age, mode of injury and the time lag between injury and surgery achieved statistically significant results. Conclusion: In the current study, elapsed time between the injury and surgery, age of the patient, preoperative visual acuity and mode of injury were found to be adversely affecting the final visual outcome. Recognizing these factors prior to surgical intervention or intraoperatively can help the surgeon in evidence-based counseling of the trauma victim and family.

Existence of doctors with high performance is one of the necessary conditions to provide high quality services. There are different motivations, which could affect their performance. Recognizing Factors which effect the performance of doctors as an effective force in health care centers is necessary. The aim of this article was evaluate the effective factors which influence on clinical performance of general surgery of Tehran University of Medical Sciences in 2015. This is a cross-sectional qualitative-quantitative study. This research conducted in 3 phases-phases I: (use of library studies and databases to collect data), phase II: localization of detected factors in first phase by using the Delphi technique and phase III: prioritizing the affecting factors on performance of doctors by using qualitative interviews. 12 articles were analyzed from 300 abstracts during the evaluation process. The output of assessment identified 23 factors was sent to surgeons and their assistants for obtaining their opinions. Quantitative analysis of the findings showed that "work qualification" (86.1%) and "managers and supervisors style" (50%) have respectively the most and the least impact on the performance of doctors. Finally 18 effective factors were identified and prioritized in the performance of general surgeons. The results showed that motivation and performance is not a single operating parameter and it depends on several factors according to cultural background. Therefore it is necessary to design, implementation and monitoring based on key determinants of effective interventions due to cultural background.

A physician shortage is on the horizon, and surgeons are particularly vulnerable due to attrition. Reduced job satisfaction leads to increased job turnover and earlier retirement. The purpose of this study is to delineate the risk factors that contribute to reduced job satisfaction. A cross-sectional survey of US surgeons was conducted from September 2016 to May 2017. Screening for job satisfaction was performed using the abridged Job in General scale. Respondents were grouped into more and less satisfied using the median split. Twenty-five potential risk factors were examined that included demographic, occupational, psychological, wellness, and work-environment variables. Overall, 993 respondents were grouped into more satisfied (n = 502) and less satisfied (n = 491) cohorts. Of the demographic variables, female gender and younger age were associated with decreased job satisfaction (p = 0.003 and p = 0.008). Most occupational variables (specialty, experience, academics, practice size, payment model) were not significant. However, increased average hours worked correlated with less satisfaction (p = 0.008). Posttraumatic stress disorder, burnout, wellness, all eight work-environment variables, and unhappiness with career choice were linked to reduced job satisfaction (p = 0.001). A surgeon shortage has serious implications for health care. Job satisfaction is associated with physician retention. Our results suggest women and younger surgeons may be at increased risk for job dissatisfaction. Targeted work-environment interventions to reduce work-hours, improve hospital culture, and provide adequate financial reimbursement may promote job satisfaction and wellness.

Operative resection can be associated with improved survival for selected patients with stage IV malignancies but may also be associated with prohibitive acute morbidity and mortality. We sought to evaluate rates of acute morbidity and mortality after lung resection in patients with disseminated malignancy with primary lung cancer and non-lung cancer pulmonary metastatic disease. For 2011-2012, 6,360 patients were identified from the American College of Surgeons National Surgical Quality Improvement Program undergoing lung resections, including 603 patients with disseminated malignancy. Logistic regression analyses were used to compare outcomes between patients with and without disseminated malignancy. After controlling for preoperative and intraoperative differences, we observed no statistically significant differences in rates of 30-day overall and serious morbidity or mortality between disseminated malignancy and non-disseminated malignancy patients (P > .05). Disseminated malignancy patients were less likely to have a prolonged duration of stay and be discharged to a facility compared to non-disseminated malignancy patients (P < .05). Subgroup analyses by procedure type and diagnosis showed similar results. Disseminated malignancy patients undergoing lung resections experienced low rates of overall morbidity, serious morbidity, and mortality comparable to non-disseminated malignancy patients. These data suggest that lung resections may be performed safely on carefully selected, disseminated malignancy patients with both primary lung cancer and pulmonary metastatic disease, with important implications for multimodality care.

Effect of variations in depth of neuromuscular blockade on rating of surgical conditions by surgeon and anesthesiologist in patients undergoing laparoscopic renal or prostatic surgery (BLISS trial): study protocol for a randomized controlled trial.
Boon, Martijn; Martini, Christian H; Aarts, Leon P H J; Bevers, Rob F M; Dahan, Albert
Surgical conditions in laparoscopic surgery are largely determined by the depth of neuromuscular relaxation. Especially in procedures that are confined to a narrow working field, such as retroperitoneal laparoscopic surgery, deep neuromuscular relaxation may be beneficial. Until recently, though, deep neuromuscular block (NMB) came at the expense of a variety of issues that conflicted with its use. However, with the introduction of sugammadex, rapid reversal of a deep NMB is feasible. In the current protocol, the association between the depth of NMB and rating of surgical conditions by the surgeon and anesthesiologist is studied. This is a single-center, prospective, randomized, blinded, parallel group and controlled trial. Eligible patients are randomly assigned to one of two groups: (1) deep NMB (post-tetanic count, one or two twitches; n = 12) and (2) moderate NMB (train-of-four, 1 to 2 twitches, n = 12) by administration of high-dose rocuronium in Group 1 and a combination of atracurium and mivacurium in Group 2. The NMB in Group 1 is reversed by 4 mg/kg sugammadex; the NMB in Group 2 by 1 mg neostigmine and 0.5 mg atropine. Patients are eligible if they are over 18 years, willing to sign the informed consent form, and are scheduled to undergo an elective laparoscopic renal procedure or laparoscopic prostatectomy. A single surgeon performs the surgeries and rates the surgical conditions on a five-point surgical rating scale (SRS) ranging from 1 (poor surgical conditions) to 5 (excellent surgical conditions). The intra-abdominal part of the surgeries is captured on video and a group of five anesthesiologists and ten surgical experts will rate the videos using the same SRS. The primary analysis will be an intention-to-treat analysis. Evaluation will include the association between the level of NMB and SRS, as obtained by the surgeon performing the procedure and the agreement between the scoring of the images by anesthesiologists and surgeons. We aim to show that

Variation in referral rates for physical therapy exists at both the individual physician and practice levels. The purpose of this study was to explore the influence of physician and practice characteristics on referral for physical therapy in patients with traumatic lower-extremity injury. A cross-sectional survey was conducted. In 2007, a Web-based survey questionnaire was distributed to 474 surgeon members of the Orthopaedic Trauma Association. The questionnaire measured physician and practice characteristics, outcome expectations, and attitude toward physical therapy. Referral for physical therapy was based on case vignettes. The response rate was 58%. Surgeons reported that 57.6% of their patients would have a positive outcome from physical therapy and 24.2% would have a negative outcome. The highest physical therapy expectations were for the appropriate use of assistive devices (80.7%) and improved strength (force-generating capacity) (76.4%). The lowest outcome expectations were for improvements in pain (35.9%), coping with the emotional aspects of disability (44.1%), and improvements in workplace limitations (51.4%). Physicians reported that 32.6% of their patients referred for physical therapy would have no improvement beyond what would occur with a surgeon-directed home exercise program. Multivariate analyses showed positive physician outcome expectations to have the largest effect on referral for physical therapy (odds ratio=2.7, Pphysical therapy based mostly on expectations for physical and motor outcomes, but may not be considering pain relief, return to work, and psychosocial aspects of recovery. Furthermore, low referral rates may be attributed to a preference for surgeon-directed home-based rehabilitation. Future research should consider the efficacy of physical therapy for pain, psychosocial and occupational outcomes, and exploring the differences between supervised physical therapy and physician-directed home exercise programs.

consecutive single-institution Danish cohort of 1148 patients undergoing RP between 1995 and 2011 was investigated. To analyse the impact of covariates on risk of PSM, a multivariate logistic regression model was used, including cT category, biopsy Gleason score, prostate-specific antigen (PSA), percentage...... positive biopsies for cancer (PPB), surgeon and surgical technique. RESULTS: The overall rate of PSM was 31.4%. The risk of PSM depended (p value for Wald χ(2)) on PSA (p PSA, the risk of PSM...... to the referent surgeon. Nerve-sparing surgery increased the risk of PSM by 50% compared to wide resection (OR = 1.5, 95% CI 1.0-2.1, p = 0.03). CONCLUSION: Both preoperative and surgical parameters affect the risk of PSM after radical prostatectomy. Surgeon and high preoperative PSA, PPB and cT category were...

Previous studies regarding the outcome of laparoscopic cholecystectomy(LC) in men have reported inconsistent findings. We conducted thisprospective study to test the hypothesis that the outcome of LC is worse inmen than women. Between 1997 and 2002, a total of 391 consecutive LCs wereperformed by a single surgeon at King Fahd Hospital of the University. Wecollected and analyzed data including age, gender, body mass index (kg/m2),the American Society of Anesthesiologists (ASA) class, mode of admission(elective or emergency), indication for LC (chronic or acute) cholecystitis[AC]), comorbid disease, previous abdominal surgery, conversion to opencholecystectomy, complications, operation time and length of postoperativehospital stay. Bivariate analysis showed that both genders were matched forage, ASA class and mode of admission. The incidence of AC (P=0.003) andcomobrid disease (P=0.031) were significantly higher in men. Women weresignificantly more obese than men (P<0.001) and had a higher incidence ofprevious abdominal surgery (P=0.017). There were no statistical differencesbetween genders with regards to rate of conversion (P=0.372) andcomplications (P=0.647) and operation time (P=0.063). The postoperative staywas significantly longer in men than women (P=0.001). Logistic regressionanalysis showed that male gender was not an independent predictor ofconversion (Odds ratio [or] = 0.37 and P=0.43) or complications (OR=0.42,P=0.42). Linear regression analysis showed that male gender was not anindependent predictor of the operation time, but was associated with a longerpostoperative stay (P=0.02). Male gender is not an independent risk factorfor satisfactory outcome of LC in the experience of a single surgeon. (author)

Systemic-to-pulmonary shunt failure is a potentially catastrophic complication. We analyzed a large multicenter clinical registry to describe the prevalence and evaluate risk factors. Infants (aged ≤365 days) undergoing shunt operations (systemic artery-to-pulmonary artery or systemic ventricle-to-pulmonary artery) in The Society of Thoracic Surgeons Congenital Heart Surgery Database (STS-CHSD) from 2010 to 2015 were included. Multivariable logistic regression was used to evaluate risk factors for in-hospital shunt failure. Model covariates included patient characteristics, preoperative factors, procedural factors including shunt type, and center effects. Centers with more than 15% missing data for key covariates were excluded. Shunt operations were performed in 9,172 infants (118 centers). In-hospital shunt failure occurred in 674 (7.3%). In multivariable analysis, risk factors for in-hospital shunt failure included lower weight at operation (odds ratio [OR], 1.35; p = 0.001), preoperative hypercoagulable state (OR, 2.47; p = 0.031), and the presence of any other STS-CHSD preoperative risk factors (OR, 1.24; p = 0.038). Shunt failure was less likely with a systemic ventricle-to-pulmonary artery shunt than a systemic artery-to-pulmonary artery shunt (OR, 0.65; p = 0.020). Neither cardiopulmonary bypass nor single-ventricle diagnosis was a risk factor for shunt failure. Patients with in-hospital shunt failure had significantly higher rates of operative mortality (31.9% vs 11.1%, p failure is common, and associated mortality risk is high. These data highlight at-risk patients and procedural cohorts that warrant expectant surveillance and may benefit from enhanced antithrombotic prophylaxis or other management strategies to reduce shunt failure. These findings may inform planning of future clinical trials. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Thoughts and attitudes of plastic surgeons about having cosmetic surgery on themselves remain obscure for the most part and pose an attractive subject to study. A survey was distributed to a random sample of 2635 American Society of Plastic Surgeons member and candidate member surgeons to determine plastic surgeons' interest in both minimally invasive cosmetic procedures and cosmetic surgical procedures, selection of facility type, selection of surgeon, and their satisfaction level. There were 276 responses. Sixty-two percent of the plastic surgeons had undergone at least one type of minimally invasive cosmetic procedure. Female plastic surgeons had significantly more minimally invasive cosmetic procedures compared with male plastic surgeons (84.9 versus 57 percent; p cosmetic surgery. The most common cosmetic surgical procedure was liposuction of the trunk and/or extremity (18.6 percent). Male plastic surgeons were more likely to have a procedure than men in the general population, and female plastic surgeons were less likely to have breast augmentation than the general population. The percentage of operations conducted by a plastic surgeon was 88.2 percent. The percentage performed by a nationally known surgeon was 45.3 percent; 75.9 percent of plastic surgeons selected a surgeon who was certified by the American Board of Plastic Surgery. The satisfaction rate was 90 percent. The survey provides insight on the stance of American Society of Plastic Surgeons member and candidate member surgeons on the subject. To the authors' knowledge, this is the first survey designed for this purpose.

This study aimed to investigate factors affecting length of hospital stay and mortality of a specific group of patients with infected diabetic foot ulcer who underwent surgical drainage without major amputation, which is frequently encountered by orthopedic surgeons. Data on length of hospital stay, mortality, demographics, and other medical information were collected for 79 consecutive patients (60 men, 19 women; mean age, 66.1 [SD, 12.3] yr) with infected diabetic foot ulcer who underwent surgical drainage while retaining the heel between October 2003 and May 2013. Multiple linear regression analysis was performed to determine factors affecting length of hospital stay, while multiple Cox regression analysis was conducted to assess factors contributing to mortality. Erythrocyte sedimentation rate (ESR, P=0.034), glycated hemoglobin (HbA1c) level (P=0.021), body mass index (BMI, P=0.001), and major vascular disease (cerebrovascular accident or coronary artery disease, P=0.004) were significant factors affecting length of hospital stay, whereas age (P=0.005) and serum blood urea nitrogen (BUN) level (P=0.024) were significant factors contributing to mortality. In conclusion, as prognostic factors, the length of hospital stay was affected by the severity of inflammation, the recent control of blood glucose level, BMI, and major vascular disease, whereas patient mortality was affected by age and renal function in patients with infected diabetic foot ulcer undergoing surgical drainage and antibiotic treatment.

The treatment of developmental dysplasia of the hip (DDH) in children remains controversial. We describe the clinical and radiological outcomes of 47 hips in 43 children treated with open surgery by one surgeon between 2004 and 2008 for DDH. The mean age at operation was 25 months (5 to 113) with a mean follow up of 89 months (22 to 169). At the latest follow up 40 of the 45 hips where Severin grades were recordable (89%) were graded as excellent or good, Severin class I or II. Clinically significant AVN (grade II to III according to the Kalamchi and MacEwen classification) was seen in 6 (13%) of the hips. We found a pelvic osteotomy to be a risk factor for AVN (p 0.02) and age at operation to be a risk factor for poor morphology at final follow up (p 0.03). Over 18 months old a pelvic osteotomy should be performed in selective cases depending on intra-operative stability, but we will now consider doing this as a staged procedure and delaying the osteotomy for a period of time after open reduction to reduce the risk of AVN.

Surgical costs are under scrutiny and surgeons are being held increasingly responsible for cost containment. In some instances, implants are the largest component of total procedure cost, yet previous studies reveal that surgeons' knowledge of implant prices is poor. Our study aims to (1) understand drivers behind implant selection and (2) assess whether educating surgeons about implant costs affects implant selection. We surveyed 226 orthopedic surgeons across 6 continents. The survey presented 8 clinical cases of upper extremity fractures with history, radiographs, and implant options. Surgeons were randomized to receive either a version with each implant's average selling price ("price-aware" group), or a version without prices ("price-naïve" group). Surgeons selected a surgical implant and ranked factors affecting implant choice. Descriptive statistics and univariate, multivariable, and subgroup analyses were performed. For cases offering implants within the same class (eg, volar locking plates), price-awareness reduced implant cost by 9% to 11%. When offered different models of distal radius volar locking plates, 25% of price-naïve surgeons selected the most expensive plate compared with only 7% of price-aware surgeons. For cases offering different classes of implants (eg, plate vs external fixator), there was no difference in implant choice between price-aware and price-naïve surgeons. Familiarity with the implant was the most common reason for choosing an implant in both groups (35% vs 46%). Price-aware surgeons were more likely to rank cost as a factor (29% vs 21%). Price awareness significantly influences surgeons' choice of a specific model within the same implant class. Merely including prices with a list of implants leads surgeons to select less expensive implants. This implies that an untapped opportunity exists to reduce surgical expenditures simply by enhancing surgeons' cost awareness. Economic/Decision Analyses I. Copyright © 2017 American

Extensive surgical resection remains nowadays the best treatment available for most intra-axial brain tumours. However, postoperative sequelae can outweigh the potential benefits of surgery. The goal of this study has been to review the results of this treatment in our Department in order to quantify morbidity and mortality and determine predictive risk factors for each patient. We report a retrospective study of 200 patients submitted to a craniotomy for intra-axial brain tumours including gliomas and metastases. Postoperative major complications are analysed and related to different variables. An exhaustive review of the literature concerning the main controversial points about primary and metastatic brain tumours surgery is done. The overall major complication rate was 27.5%, with neurological complications being the most frequently encountered. We did not find a statistically significant relation between them and the grade of eloquence of the tumoural area. Infratentorial tumour location, previous radiotherapy and reoperations were factors strongly related to the incidence of regional complications. Age over 60 and severe concomitant disease were risk factors for systemic complications. The results from published series concerning surgical complications after craniotomies for brain tumours are not comparable because of the lack of homogeneity between them. The knowledge of the complications rate in each particular neurosurgical department turns out essentially to provide the patient with tailored information about risks before surgery.

GreenLightTM procedure is an effective and economical way of treatment of benign prostate hyperplasia (BPH); there are almost a million of patients treated with GreenLightTM worldwide. During the surgical procedure, the surgeon or physician will rely on the monitoring video system to survey and confirm the surgical progress. There are a few obstructions that could greatly affect the image quality of the monitoring video, like laser glare by the tissue and body fluid, air bubbles and debris generated by tissue evaporation, and bleeding, just to name a few. In order to improve the physician's visual experience of a laser surgical procedure, the system performance parameter related to image quality needs to be well defined. However, since image quality is the integrated set of perceptions of the overall degree of excellence of an image, or in other words, image quality is the perceptually weighted combination of significant attributes (contrast, graininess …) of an image when considered in its marketplace or application, there is no standard definition on overall image or video quality especially for the no-reference case (without a standard chart as reference). In this study, Subjective Quality Factor (SQF) and acutance are used for no-reference image quality evaluation. Basic image quality parameters, like sharpness, color accuracy, size of obstruction and transmission of obstruction, are used as subparameter to define the rating scale for image quality evaluation or comparison. Sample image groups were evaluated by human observers according to the rating scale. Surveys of physician groups were also conducted with lab generated sample videos. The study shows that human subjective perception is a trustworthy way of image quality evaluation. More systematic investigation on the relationship between video quality and image quality of each frame will be conducted as a future study.

Surgeons and residents in training receive little, if any, formal education in the economic side of clinical practice during medical school or residency. As medical professionals face shrinking reimbursement, loss of control over health care decisions, and limited resources, surgical specialties must reevaluate the need to teach their members business survival skills. Before designing business related-teaching modules, educators must know the exact gaps in knowledge that exist among surgeons. This article reports a survey of 133 surgeons in the Midwest who were asked to rate their knowledge base in 11 business topics relevant to the practice of medicine. The survey showed that the average surgeon perceives himself or herself to be poorly equipped to understand basic financial accounting principles, financial markets, economics of health care, tools for evaluating purchases, marketing, budgets, antitrust and fraud and abuse regulations, and risk and return on investments. Armed with this data, teaching faculty, health care systems, and medical specialty societies should design business education seminars to better position surgical specialists and trainees to communicate with insurers, hospital administrators, health care organizations, and their own personal financial advisors.

Extensor tendon ruptures in the rheumatoid wrist are usually restored by extensor tendon reconstruction surgery. However, the factors significantly correlated with the outcomes of extensor tendon reconstruction have not been defined. We examined factors showing a statistically significant correlation with postoperative active motion after tendon reconstruction. Spontaneous extensor tendon ruptures of 66 wrists in patients (mean age, 52.6 yrs) with rheumatoid arthritis (RA) were evaluated. All patients underwent tendon reconstruction surgery with wrist arthroplasty or arthrodesis. Active ranges of motion of the affected fingers were evaluated at 12 weeks postsurgery. Statistical significance was determined using multiple and single regression analyses. Forty-six (69.6%) wrists had "good" results, while 13 (19.7%) and 7 (10.6%) wrists had "fair" and "poor" results, respectively. In multiple regression analysis, an increased number of ruptured tendons and the age at operation were independent variables significantly correlated with the postoperative active motion of reconstructed tendons (p = 0.009). Single regression analysis also showed a significant association between the number of ruptured tendons and surgical delay (p = 0.02). The number of ruptured extensor tendons was significantly correlated with the results of tendon reconstruction, and the number of ruptured tendons was significantly correlated with preoperative surgical delay. Our results indicate that, in patients presenting with possible finger extensor tendon rupture, rheumatologists should consult with hand surgeons promptly to preserve hand function.

To determine the incidence of infection and associated risk factors, after elective arthroscopy. Retrospective case study. Horses (n=1079) undergoing elective arthroscopy. Medical records of all horses that underwent elective arthroscopy between 2006 and 2013 were reviewed. Age, gender, breed, surgeon, number of joints operated, total anesthetic time, perioperative antimicrobial administration, and the presence and size of osteochondral fragments/subchondral lesions were recorded. For each operated joint, the development of postoperative infection (surgical site infection [SSI] and/or septic arthritis) and long-term outcome (>6 months) were recorded. Multivariate logistic regression was used to test for association between the independent variables and the dependent outcomes. A total of 1741 joints in 1079 horses underwent arthroscopy. SSI without septic arthritis occurred in 1 fetlock joint (0.14%), 1 tibiotarsal joint (0.19%), and 6 femoropatellar joints (1.67%). Thirteen joints (0.75%) were diagnosed with septic arthritis, including 1 fetlock joint (0.14%), 4 tibiotarsal joints (0.74%), and 8 femoropatellar joints (2.23%). The probability of postoperative SSI was higher when large lesions (>40 mm long) were treated, compared to medium (20-40 mm, P = .005) and small (septic arthritis (P septic arthritis rate (P = .028). Septic arthritis after elective arthroscopy was more likely in the presence of SSI and younger age. Horses with large lesions were at risk for SSI, which translated into a higher incidence of postoperative septic arthritis after femoropatellar arthroscopy. © 2017 The American College of Veterinary Surgeons.

Surgical procedures on obese patients are expected to have a high incidence of surgical site infection (SSI). The identification of pre-operative or early post-operative risk factors for SSI may help the surgeon to identify subjects in risk and adequately optimize their status. We conducted a study of the association of comorbidities and pre- and post-operative analytical variables with SSI following laparoscopic sleeve gastrectomy for the treatment of morbid obesity. We performed a prospective study of all morbidly obese patients undergoing laparoscopic sleeve gastrectomy as a bariatric procedure between 2007 and 2011. An association of clinical and analytical variables with SSI was investigated. The study included 40 patients with a mean pre-operative body mass index (BMI) of 51.2±7.9 kg/m(2). Surgical site infections appeared in three patients (7.5%), of whom two had an intra-abdominal abscess located in the left hypochondrium and the third had a superficial incisional SSI. Pre-operatively, a BMI >45 kg/m(2) (OR 8.7; p=0.008), restrictive disorders identified by pulmonary function tests (OR 10.0; p=0.012), a serum total protein concentration 30 mcg/dL (OR 13.0; p=0.003), and a mean corpuscular volume (MCV) operative SSI. Post-operatively, a serum glucose >128 mg/dL (OR 4.7; p=0.012) and hemoglobin operative anemia and hyperglycemia as risk factors for SSI. In these situations, the surgeon must be aware of and seek to control these risk factors.

Sentinel lymph node biopsy (SLNB) has been unevenly adopted into practice in Canada. In this qualitative study, the authors explored individual, institutional, and policy factors that may have influenced SLNB adoption. This information will guide interventions to improve SLNB implementation. Qualitative methodology was used to examine factors influencing SLNB adoption. Grounded theory guided data collection and analysis. Semistructured interviews were based on Roger's diffusion of innovation theory. Purposive and snowball sampling was used to identify participants. Semistructured telephone interviews were conducted with urban, rural, academic, and community health care providers and administrators to ensure all perspectives and motivations were explored. Two individuals independently analyzed data and achieved consensus on emerging themes and their relationship. A total of 43 interviews were completed with 21 surgeons, 5 pathologists, 7 nuclear medicine physicians, and 10 administrators. Generated themes included awareness of SLNB with the exception of some administrators, acknowledged advantage of SLNB, SLNB compatibility with beliefs regarding axillary staging, acknowledgment that SLNB was a complex innovation to adopt, extensive trialing of SLNB prior to adoption, observable benefits with SLNB, acknowledgment that hospital-level administrative support enabled adoption, desire for a provincial policy supporting SLNB to assist in hospital-level adoption, requirement of a local high-volume breast surgery champion who communicated extensively with team to facilitate local adoption, and need for credentialing of SLNB to ensure quality. SLNB is a complex innovation to adopt. Successful adoption was assisted by a high-volume breast cancer surgical champion, interprofessional communication, and administrative support.

In 1975, the American Society of Oral Surgeons officially changed its name to the American Association of Oral and Maxillofacial Surgeons. This change was intended to address the specialty's expanding surgical scope. However, today, many health care professionals continue to use the term oral surgeon. This study was undertaken to determine if students' perception of the oral and maxillofacial surgeon's (OMS) surgical scope would change when oral and maxillofacial surgeon was used instead of oral surgeon. This cross-sectional study surveyed undergraduate and dental students' choice of specialist to treat 21 different conditions. The independent variable was the specialty term (oral and maxillofacial surgeon vs oral surgeon). The dependent variables were specialists chosen for the procedure (ear, nose, and throat surgeon; plastic surgeon; OMS or oral surgeon; periodontist; other). The test of proportions (z test) with the Yates correction was performed for data analysis. Of the 280 senior dental students who were surveyed, 258 surveys were included in the study. Dental students' perception of the OMS's surgical scope increased significantly from 51% to 55% when oral and maxillofacial surgeon was used instead of oral surgeon. Of the 530 undergraduate upper division science students who were surveyed, 488 surveys were included in the study. Undergraduate upper division science students' perception of the OMS's surgical scope increased significantly from 23% to 31% when oral and maxillofacial surgeon was used as an option instead of oral surgeon. The use of oral and maxillofacial surgeon increased students' perception of the OMS's surgical scope. This study also suggested that students were not fully aware of the magnitude of the OMS's scope of practice. The current dichotomy and inconsistent use of the specialty's official term adds to the confusion and to misunderstanding. Therefore, OMSs should universally refer to themselves as oral and maxillofacial surgeons and

This study aimed to quantitatively summarize the risk factors associated with surgical site infection after open reduction and internal fixation of tibial plateau fracture. Medline, Embase, CNKI, Wanfang database and Cochrane central database were searched for relevant original studies from database inception to October 2016. Eligible studies had to meet quality assessment criteria according to the Newcastle-Ottawa Scale, and had to evaluate the risk factors for surgical site infection after open reduction and internal fixation of tibial plateau fracture. Stata 11.0 software was used for this meta-analysis. Eight studies involving 2214 cases of tibial plateau fracture treated by open reduction and internal fixation and 219 cases of surgical site infection were included in this meta-analysis. The following parameters were identified as significant risk factors for surgical site infection after open reduction and internal fixation of tibial plateau fracture (p operative time (OR 2.15; 95% CI 1.53-3.02), tobacco use (OR 2.13; 95% CI 1.13-3.99), and external fixation (OR 2.07; 95% CI 1.05-4.09). Other factors, including male sex, were not identified as risk factors for surgical site infection. Patients with the abovementioned medical conditions are at risk of surgical site infection after open reduction and internal fixation of tibial plateau fracture. Surgeons should be cognizant of these risks and give relevant preoperative advice. Copyright © 2017. Published by Elsevier Ltd.

Surgical site infection (SSI) following minor surgery contributes to patient morbidity and compromises cosmetic outcomes. The purpose of this study was to determine the incidence of and risk factors for SSI after dermatological surgery in general practice. A prospective, observational study which assessed infection among 972 patients was conducted in regional north Queensland, Australia. Consecutive patients presenting for minor skin excisions were invited to participate. Wounds were assessed for SSI at the time of removal of sutures. Infection occurred in 85 of the 972 excisions; thus, the overall incidence of infection was 8.7% (95% confidence interval 6.5-11.0). Excisions in the upper (Prisk factors for wound infection. The length of the excision (Prisk factors for infection. Diabetes was not found to be an independent risk factor for infection (P=0.891). Prophylactic antibiotics are probably prescribed excessively or inappropriately for dermatological surgery, and overall we wish to discourage their use. The results of this study may encourage the more judicial use of prophylactic antibiotics by defining high-risk procedures, such as excisions from the extremities, excision of BCC or SCC, and larger excisions, and patients who are at high risk for infection, such as ex-smokers. © 2012 The International Society of Dermatology.

To identify trends and risk factors for early surgical site infection (SSI) following cesarean delivery (CD). A population-based study comparing characteristics of women who have and have not developed post cesarean SSI was conducted. Deliveries occurred between the years 1988 and 2013 in a tertiary medical center. A multivariable logistic regression model, with backwards elimination, was used to control for confounders. Of the 41 375 cesarean deliveries performed during the study period, 1521 (3.7%) were complicated with SSI. SSI rates significantly deceased over the years, from 7.4% in 1988 to 1.5% in 2012. Using a multivariable regression model, the following independent risk factors for SSI were identified: obesity (OR 2.0; 95% CI, 1.6-2.5); previous CD (OR 1.8; 95% CI, 1.6-2.0); hypertensive disorders (OR 1.4; 95% CI, 1.2-1.6); premature rupture of membranes (OR 1.3; 95% CI, 1.1-1.6); gestational diabetes mellitus (GDM, OR 1.2; 95% CI, 1.1-1.4); and recurrent pregnancy losses (OR 1.2; 95% CI, 1.1-1.5). Independent risk factors for post-cesarean SSI include obesity, GDM, hypertensive disorders of pregnancy, premature rupture of membranes, and recurrent pregnancy losses. Information regarding higher rates of SSI and preventative measures should be provided to these high-risk women prior to surgery.

Approximately five percent of patients who undergo surgery develop surgical site infections (SSIs) which are associated with an extra seven days as an inpatient and with increased postoperative mortality. The competence and technique of the surgeon is considered important in preventing SSI. We have reviewed the evidence on different aspects of surgical technique and its role in preventing SSI. The most recent guidelines from the National Institute for Health and Clinical Excellence in the UK recommend avoiding diathermy for skin incision even though this reduces incision time and blood loss, both associated with lower infection rates. Studies comparing different closure techniques, i.e. continuous versus interrupted sutures, have not found a statistically significant difference in the SSI rate, but using continuous sutures is quicker. For contaminated wounds, the surgical site should be left open for four days to allow for treatment of local infection before subsequent healing by primary intention. Surgical drains should be placed through separate incisions, closed suction drains are preferable to open drains, and all drains should be removed as soon as possible. There are relatively few large studies on the impact of surgical techniques on SSI rates. Larger multicentre prospective studies are required to define what aspects of surgical technique impact on SSI, to better inform surgical practice and support education programmes for surgical trainees.

The aims of this study were to characterize the frequency of missing data in the National Surgical Quality Improvement Program (NSQIP) database and to determine how missing data can influence the results of studies dealing with elderly patients with a fracture of the hip. Patients who underwent surgery for a fracture of the hip between 2005 and 2013 were identified from the NSQIP database and the percentage of missing data was noted for demographics, comorbidities and laboratory values. These variables were tested for association with 'any adverse event' using multivariate regressions based on common ways of handling missing data. A total of 26 066 patients were identified. The rate of missing data was up to 77.9% for many variables. Multivariate regressions comparing three methods of handling missing data found different risk factors for postoperative adverse events. Only seven of 35 identified risk factors (20%) were common to all three analyses. Missing data is an important issue in national database studies that researchers must consider when evaluating such investigations.

An Act of Parliament in 1540 uniting the barbers and surgeons to form the Barber-Surgeons' Company represented an important foundation stone towards better surgery in England. Thomas Vicary, who played a pivotal role in promoting this union, was a leading surgeon in London in the middle of the 16th century. While Vicary made no direct contribution to surgical knowledge, he should be remembered primarily as one who contributed much towards the early organization and teaching of surgery and to the consequent benefits that flowed from this improvement.

Different modalities of treatment for hip fractures have been discussed in the literature; however, practice may vary between centres. A survey was conducted on participants at an international AO course to assess the current management of pertrochanteric fractures (AO/OTA 31-A2) and displaced, non-impacted, subcapital fractures (AO/OTA 31-B3) in a 35-year-old patient and an 85-year-old patient. Surgeons taking part in an international orthopaedic course were invited to participate in a survey and were divided into two groups: inexperienced (one-to-three years since qualification) and experienced (four or more years). A survey was conducted to assess the management modalities used for pertrochanteric fractures (AO/OTA 31-A2) and displaced, non-impacted, subcapital fractures (AO/OTA 31-B3) in a 35-year-old patient and an 85-year-old patient. Fifty-two surgeons participated: 18 were inexperienced and 34 were experienced. The method of operative fixation for the pertrochanteric fracture was gamma-nailing for 95% of the surgeons in the inexperienced group; in the experienced group, 56% opted for gamma-nailing and 38% for dynamic hip screw (DHS). For the displaced subcapital fracture in a 35-year-old, screw fixation was the dominant treatment option for both groups. For the displaced subcapital fracture in an 85-year-old, most of the surgeons in both groups preferred hemiarthroplasty: 59% in the inexperienced group chose cemented bipolar hemiarthroplasty and 12% uncemented, whereas 56% of the experienced group suggested cemented bipolar hemiarthroplasty and 25% uncemented. This survey shows that a variety of methods are used to treat femoral neck fractures. A prospective randomised trial has shown the DHS to be the implant of choice for pertrochanteric fractures; however, this was not considered an option in the inexperienced group of surgeons and was the treatment of choice in only 13 out of 34 experienced surgeons. There is a general consensus for femoral head

Preoperative infliximab treatment may influence postoperative infectious complications in patients with Crohn's disease. The aim of this study was to identify predictors of surgical site infection after surgery for Crohn's disease and evaluate the effects of preoperative infliximab administration. We performed a prospective surveillance and review of surgical site infections. This study was conducted in the Surgical Department of Hyogo College of Medicine. A total of 405 consecutive patients with Crohn's disease who underwent abdominal surgery between January 2008 and December 2011 were included. Infection was diagnosed by the infection control team. The possible risk factors were analyzed by using logistic regression analyses to determine their predictive significance. Within the patient population, 20% of patients received infliximab, and 60% had penetrating disease. The median duration from the last infliximab infusion to surgery was 43 days (range, 4-80). The overall incidence of surgical site infection was 27%. The incidence of incisional surgical site infection was 18%, and the organ/space surgical site infection rate was 8%. In the multivariate analysis, proctectomy was the highest risk factor for all surgical site infection (OR, 3.4-11.8; p risk factor for surgical site infection. By contrast, there was a significantly reduced risk of incisional surgical site infection in patients with penetrating disease who received infliximab (OR, 0.1; p risk factor for surgical site infection in patients with Crohn's disease. The administration of preoperative infliximab was not a risk factor for surgical site infection.

The surgical safety checklist (SSC) is meant to enhance patient safety but studies of its impact conflict. This study explored factors that influenced SSC adherence to suggest how its impact could be optimized. Participants were recruited purposively by profession, region, hospital type and time using the SSC. They were asked to describe how the SSC was adopted, associated challenges, perceived impact, and suggestions for improving its use. Grounded theory and thematic analysis were used to collect and analyse data. Findings were interpreted using an implementation fidelity conceptual framework. Fifty-one participants were interviewed (29 nurses, 13 surgeons, 9 anaesthetists; 18 small, 14 large and 19 teaching hospitals; 8 regions; 31 had used the SC for ≤12 months, 20 for 13+ months). The SSC was inconsistently reviewed, and often inaccurately documented as complete. Adherence was influenced by multiple issues. Extensive modification to accommodate existing practice patterns eliminated essential interaction at key time points to discuss patient management. Staff were often absent or not paying attention. They did not feel it was relevant to their work given limited evidence of its effectiveness, and because they were not engaged in its implementation. Organizations provided little support for implementation, training, monitoring and feedback, which are needed to overcome these, and other individual and team factors that challenged SSC adherence. Responses were similar across participants with different characteristics. Multiple processes and factors influenced SSC adherence. This may explain why, in studies evaluating SSC impact, outcomes were variable. Recommendations included continuing education, time for pilot-testing, and engaging all staff in SSC review. Others may use the implementation fidelity framework to plan SSC implementation or evaluate SSC adherence. Further research is needed to establish which SSC components can be modified without compromising

Out of 484 cases with breast conserving surgery between April 1989 and March 1999, surgical procedures of 34 cases were changed to total mastectomy due to positive surgical margins. In this study we evaluated a clinical significance of surgical margin in relation to clinicopathological factors and prognoses. Ninety-nine cases (20.5%) had positive margins that were judged when cancer cells existed within 5 mm from margin. In multivariate analysis of factors for surgical margin, EIC-comedo status, ly, located site, proliferative activity, and age were significant and independent factors. Regarding local recurrence, positive margin, age, ER and proliferative activity were significant factors in multivariate analysis, especially in cases not receiving postoperative radiation therapy. Radiation therapy may be beneficial for patients with positive surgical margin. And patients with breast recurrence alone had significantly higher survival rates. Therefore, it is suggested that surgical margin may not reflect survival, although it is a significant factor for local recurrence. (author)
Full Text Available Current literature on risk factors for surgical site infection (SSI in dermatological surgery in the absence of antibiotic prophylaxis is limited. The aim of this study was to retrospectively evaluate patients presenting for dermatological surgery. A total of 1,977 procedures were reviewed. SSI was clinically suspected in 79 (4.0% patients and confirmed by culture in 38 (1.9%. Using the strictest definition of SSI (clinical symptoms with positive culture significantly higher risk of SSI was found for location on the ear (odds ratio (OR 6.03, 95% confidence interval (95% CI 2.12–17.15, larger defects (OR 1.08 per cm2 increase, 95% CI 1.03–1.14, closure with flaps (OR 6.35, 95% CI 1.33–30.28 and secondary intention (OR 3.01, 95% CI 1.11–8.13. These characteristics were also associated with higher risk of clinically suspected SSI regardless of culture results with slightly lower ORs. In conclusion, the risk of acquiring a SSI is increased in surgeries performed on the ear, in larger wounds and in defects closed with flaps or healed by secondary intention.

Comparative studies suggest functional and perioperative superiority of robot-assisted radical prostatectomy (RARP) over open radical prostatectomy (ORP). To determine whether high-volume experienced open surgeons can improve their functional and oncologic outcomes with RARP and, if so, how many cases are required to surpass ORP outcomes and reach the learning curve plateau. A prospective observational study compared two surgical techniques: 1552 consecutive men underwent RARP (866) or ORP (686) at a single Australian hospital from 2006 to 2012, by one surgeon with 3000 prior ORPs. Demographic and clinicopathologic data were collected prospectively. The Expanded Prostate Cancer Index Composite quality of life (QoL) questionnaire was administered at baseline, 1.5, 3, 6, 12, and 24 mo. Multivariate linear and logistic regression modelled the difference in QoL domains and positive surgical margin (PSM) odds ratio (OR), respectively, against case number. A total of 1511 men were included in the PSM and 609 in the QoL analysis. RARP sexual function scores surpassed ORP scores after 99 RARPs and increased to a mean difference at 861st case of 11.0 points (95% confidence interval [CI], 5.9-16.1), plateauing around 600-700 RARPs. Early urinary incontinence scores for RARP surpassed ORP after 182 RARPs and increased to a mean difference of 8.4 points (95% CI, 2.1-14.7), plateauing around 700-800 RARPs. The odds of a pT2 PSM were initially higher for RARP but became lower after 108 RARPs and were 55% lower (OR: 0.45; 95% CI, 0.22-0.92) by the 866th RARP. The odds of a pT3/4 PSM were initially higher for RARP but decreased, plateauing around 200-300 RARPs with an OR of 1.15 (0.68-1.95) at the 866th RARP. Limitations include single-surgeon data and residual confounding. RARP had a long learning curve with inferior outcomes initially, and then showed progressively superior sexual, early urinary, and pT2 PSM outcomes and similar pT3 PSM and late urinary outcomes.

Full Text Available In recent years, there has been a worldwide increase in childhood obesity. At present, pediatric surgeons manage a greater number of pediatric patients who are significantly overweight. Little data exist regarding the surgical challenges of obese children. This review study was designed to examine the relationship of obesity to surgical comorbidities, postoperative complications, and perioperative outcome in children, and to pediatric trauma. Obesity seems to be an independent risk factor in surgical-related pediatric morbidity and should be considered an important variable when looking at surgical outcomes in the pediatric population. Identification by and awareness among pediatric surgeons, of increased risk factors for peri/postoperative complications, will be crucial in optimizing the hospital stay and outcome of these children.

Background Although minimally invasive surgery (MIS) has been quickly embraced, the introduction of advanced procedures appears more complex. We assessed the evolution of MIS in the province of Quebec over a 5-year period to identify areas for improvement in the modern surgical era. Methods We developed, test-piloted and conducted a self-administered questionnaire among Quebec general surgeons in 2007 and 2012 to examine stated MIS practice, MIS training and barriers and facilitators to the use of MIS. Results Response rates were 51.3% (251 of 489) in 2007 and 31.3% (153 of 491) in 2012. A significant increase was observed for performance of most advanced MIS procedures, especially for colectomy for benign (66.0% v. 84.3%, p surgery for malignancy (21.0% v. 54.6%, p general surgeons in Québec. This technique appears well established in current surgical practice. The growing place of MIS in residency training seems to be a paramount part of this development. Results from this study could be used as a baseline for studies focusing on ways to further improve the MIS practice. PMID:25598180

To determine whether changing "oral and maxillofacial surgeon" (OMS) to "oral and facial surgeon" improves the perception and awareness of the OMS's role and surgical scope of practice in undergraduate biomedical and dental students. This cross-sectional study requested undergraduate and dental students to select 1 of 5 specialists to treat 21 conditions. Two different surveys were presented: 1 designating specialists as "oral and maxillofacial surgeons" and 1 designating specialists as "oral and facial surgeons." The independent variable was the specialist "oral and maxillofacial surgeon" or "oral and facial surgeon." The dependent variables included specialists chosen for the procedure (ear, nose, and throat surgeon; OMS vs oral and facial surgeon; plastic surgeon; periodontist; and "other"). The test of proportions (z test) with the Yates correction was performed. The sample was composed of 1,671 undergraduate upper division science students and 568 senior dental students. Results showed that undergraduate students' perception of an OMS's surgical scope increased significantly from 28 to 33% when "oral and facial surgeon" was used instead of "oral and maxillofacial surgeon." Dental students' perception of an OMS's surgical scope remained the same whether "oral and maxillofacial surgeon" or "oral and facial surgeon" was used. The results of this study suggest that using "oral and facial surgeon" instead of "oral and maxillofacial surgeon" increases awareness of an OMS's surgical scope of practice in undergraduate upper division science students, which could be an important step toward increasing the recognition of the profession by the general public and other non-dental medical colleagues.

Surgery for thoracic ossification of the posterior longitudinal ligament (T-OPLL) is still challenging, and factors for good surgical outcomes are unknown. To identify factors for good surgical outcomes with prospective and comparative study. Seventy-one consecutive patients who underwent posterior decompression and instrumented fusion were divided into good or poor outcome groups based on ≥50% and good outcome were analyzed. Patients with a good outcome (76%) had significantly lower nonambulatory rate and positive prone and supine position tests preoperatively; lower rates of T-OPLL, ossification of the ligamentum flavum, high-intensity area at the same level, thoracic spinal cord alignment difference, and spinal canal stenosis on preoperative magnetic resonance imaging; lower estimated blood loss; higher rates of intraoperative spinal cord floating and absence of deterioration of intraoperative neurophysiological monitoring; and lower rates of postoperative complications (P good surgical outcome. This study demonstrated that early surgery is recommended during these positive factors. Appropriate surgical planning based on preoperative thoracic spinal cord alignment difference, as well as sufficient spinal cord decompression and reduction of complications using intraoperative ultrasonography and intraoperative neurophysiological monitoring, may improve surgical outcomes.

Background Preoperative radiological assessment is important for clarification of surgical operability for advanced thymic tumors. Objective was to determine the feasibility of magnetic resonance imaging (MRI) with cine sequences for evaluation of cardiovascular tumor invasion. Patients and Methods This prospective study included patients with advanced thymoma, who underwent surgical resection. All patients received preoperative computed tomography (CT) scan and cine MRI. Results Tumor infiltration was surgically confirmed in the pericardium ( n = 12), myocardium ( n = 1), superior caval vein (SCV; n = 3), and aorta ( n = 2). A macroscopic complete resection was possible in 10 patients, whereas 2 patients with aortic or myocardial tumor invasion had R2 resection. The positive predictive value (PPV) was 50% for cine MRI compared with 0% for CT scan regarding myocardial tumor infiltration. The PPV for tumor infiltration of the aorta was 50%, with a higher sensitivity for the CT scan (100 vs. 50%). Infiltration of the SCV could be detected slightly better with cine MRI (PPV 75 vs. 66.7%). Conclusion Cine MRI seems to improve the accuracy of preoperative staging of advanced thymoma regarding infiltration of cardiovascular structures and supports the surgical approach.

The optimal workforce model for surgery has been much debated historically; in particular, whether there should be a recognised role for those successfully completing training employed as non-Consultant grade specialists. This role has been termed the 'sub-consultant' grade. This paper discusses historical and future career structures in surgery, draws international comparisons, and presents the results of a national trainee survey examining the post-Certificate of Completion of Training (CCT) non-consultant specialist grade. Junior doctors in surgical training (i.e. pre-CCT) were invited to participate in an electronic, 38-item, self-administered national training survey. Of 1710 questionnaires submitted, 1365 were appropriately completed and included in the analysis. Regarding the question 'Do you feel that there is a role in the surgical workforce for a post-CCT non-consultant specialist ("sub-consultant") grade in surgery?', 56.0% felt there was no role, 31.1% felt there was a role and 12.8% were uncertain. Only 12.6% of respondents would consider applying for such a post, while 72.4% would not and 15.0% were uncertain. Paediatric (23.3%), general (15.7%) and neurosurgery (11.6%) were the specialties with the highest proportions of trainees prepared to consider applying for such a role. For both questions, there was a significant gender difference in responses (p consultant specialist grade would impact positively upon service provision, however, only 21.6% felt it would have a positive impact on patient care, 13.9% a positive impact on surgical training, 11.1% a positive impact on the surgical profession and just 7.9% a positive impact on their surgical career. This survey indicates that the introduction of a 'sub-consultant' grade for surgeons who have completed training would be unpopular, with the majority believing it would be to the detriment of both patient care and surgical training. Changes to surgical career structures must be made in the interests of
A Comparison of 30-Day Perioperative Outcomes in Open Versus Minimally Invasive Nephroureterectomy for Upper Tract Urothelial Carcinoma: Analysis of 896 Patients from the American College of Surgeons-National Surgical Quality Improvement Program Database.

Minimally invasive surgery for nephroureterectomy (MINU) in patients with upper tract urothelial carcinoma (UTUC) is increasingly used among urologists with reported equivalent oncologic outcomes compared with open nephroureterectomy (ONU). Population-level data comparing perioperative outcomes between these approaches remain limited, however. We sought to compare perioperative outcomes between MINU and ONU in a prospectively collected national cohort of patients. Between 2006 and 2012, patients who underwent nephroureterectomy for UTUC within the American College of Surgeons-National Surgical Quality Improvement Program database were categorized into MINU or ONU. Our primary outcome of interest was 30-day perioperative complications. Secondary outcomes included use of lymph node dissection (LND), transfusion, reintervention and readmission rate, operative time, length of stay (LOS), and perioperative mortality. Multivariable logistic regression analyses were used to examine the association between outcomes and surgical approach. A total of 599 (66.9%) and 297 (33.1%) patients underwent MINU and ONU, respectively. Overall, 12.7% of patients experienced a complication within 30 days postoperatively, and the rate did not differ among surgical approaches. Patients in the MINU group, however, had a decreased LOS (PONU. MINU, however, was associated with a decreased risk of blood transfusions, thromboembolic events, reintervention, and overall LOS compared with ONU. MINU should be considered as a primary approach in select groups of patients with UTUC.

Being left-handed (LH) is considered a disadvantage in surgical training. We sought to understand the perspectives of LH trainees and surgical educators on the challenges and modifications in training LH surgeons. A survey was distributed to surgeons, surgical residents, and medical students about challenges teaching and learning surgical technique. 25 LH surgeons, 65 right-handed (RH) surgeons, and 39 LH trainees completed the survey. Compared to LH surgeons, RH surgeons reported more difficulty (46% vs 16%, p = 0.003) and less comfort teaching LH trainees (28% vs 4%, p = 0.002), and 10 (15%) reported that LH trainees have less technical ability. RH surgeons identified challenges translating technique to LH trainees and physical limitations of an environment optimized for right-handed mechanics. The disadvantage LH surgical trainees face is due to barriers in training rather than inherent lesser ability. Nonetheless, minimal modifications are made to overcome these barriers.

The number of medical students who aspire to become surgeons has been decreasing in recent years. With a vicious spiral in the decreasing number and the growing deterioration of surgeons' working conditions, there is fear of deterioration of surgical care and subsequent disintegration of overall health care in Japan. The purpose of this issue is to devise a strategy for improving surgeons' image and their working conditions to attract future medical students. However, we cannot expect a quick cure for the problem of the decreasing number of applicants for surgery since this issue is deeply related to many fundamental problems in the health care system in Japan. The challenge for surgical educators in coming years will be to solve the problem of chronic sleep deprivation and overwork of surgery residents and to develop an efficient program to meet the critical educational needs of surgical residents. To solve this problem it is necessary to ensure well-motivated surgical residents and to develop an integrated research program. No discussion of these issues would be complete without attention to the allocation of scarce medical resources, especially in relation to financial incentives for young surgeons. The authors, who are conscientious representatives of this society, would like to highlight these critical problems and issues that are particularly relevant to our modern surgical practice, and it is our sincere hope that all members of this society fully recognize these critical issues in the Japanese health care system to take leadership in improving the system. With the demonstration of withholding unnecessary medical conducts we may be able to initiate a renewal of the system and eventually to fulfill our dreams of Japan becoming a nation that can attract many patients from all over the world. Furthermore, verification of discipline with quality control and effective surgical treatment is needed to avoid criticism by other disciplines for being a self
What is the safety of nonemergent operative procedures performed at night? A study of 10,426 operations at an academic tertiary care hospital using the American College of Surgeons national surgical quality program improvement database.
Turrentine, Florence E; Wang, Hongkun; Young, Jeffrey S; Calland, James Forrest
Ever-increasing numbers of in-house acute care surgeons and competition for operating room time during normal daytime business hours have led to an increased frequency of nonemergent general and vascular surgery procedures occurring at night when there are fewer residents, consultants, nurses, and support staff available for assistance. This investigation tests the hypothesis that patients undergoing such procedures after hours are at increased risk for postoperative morbidity and mortality. Clinical data for 10,426 operative procedures performed over a 5-year period at a single academic tertiary care hospital were obtained from the American College of Surgeons National Surgical Quality Improvement Program Database. The prevalence of preoperative comorbid conditions, postoperative length of stay, morbidity, and mortality was compared between two cohorts of patients: one who underwent nonemergent operative procedures at night and other who underwent similar procedures during the day. Subsequent statistical comparisons utilized chi tests for comparisons of categorical variables and F-tests for continuous variables. Patients undergoing procedures at night had a greater prevalence of serious preoperative comorbid conditions. Procedure complexity as measured by relative value unit did not differ between groups, but length of stay was longer after night procedures (7.8 days vs. 4.3 days, p operating rooms.

Innovation is responsible for most advances in the field of surgery. Innovative approaches to solving clinical problems have significantly decreased morbidity and mortality for many surgical procedures, and have led to improved patient outcomes. While innovation is motivated by the surgeon's expectation that the new approach will be beneficial to patients, not all innovations are successful or result in improved patient care. The ethical dilemma of surgical innovation lies in the uncertainty of whether a particular innovation will prove to be a "good thing." This uncertainty creates challenges for surgeons, patients, and the healthcare system. By its very nature, innovation introduces a potential risk to patient safety, a risk that may not be fully known, and it simultaneously fosters an optimism bias. These factors increase the complexity of informed consent and shared decision making for the surgeon and the patient. Innovative procedures and their associated technology raise issues of cost and resource distribution in the contemporary, financially conscious, healthcare environment. Surgeons and institutions must identify and address conflicts of interest created by the development and application of an innovation, always preserving the best interest of the patient above the academic or financial rewards of success. Potential strategies to address the challenges inherent in surgical innovation include collecting and reporting objective outcomes data, enhancing the informed consent process, and adhering to the principles of disclosure and professionalism. As surgeons, we must encourage creativity and innovation while maintaining our ethical awareness and responsibility to patients.

There are no previous studies evaluating risk factors for surgical site infections (SSIs) and the effectiveness of prophylactic antibiotic treatment (PAT), specifically for patients operated on for lumbar disc herniation. This observational multicentre study comprises a cohort of 1,772 consecutive patients operated on for lumbar disc herniation without laminectomy or fusion at 23 different surgical units in Norway. The patients were interviewed about SSIs according to a standardised questionnaire at 3 months' follow-up. Three months after surgery, 2.3% of the patients had an SSI. Only no PAT (OR = 5.3, 95% CI = 2.2-12.7, pdisc herniation. Senior surgeons assisting inexperienced colleagues to avoid prolonged duration of surgery could also reduce the occurrence of SSI.

The increase in prevalence of certain cardiovascular risk factors increases susceptibility to vascular disease, which may create demand for surgical intervention. In our study, data collected by the American Association of Medical Colleges Physician Specialty Databook of 2012, the United States Census Bureau, and other nationwide organizations were referenced to calculate future changes in vascular surgeon supply and prevalence of people at risk for vascular disease. In 2010, there were 2853 active vascular surgeons. By 2040, the workforce is expected to linearly rise to 3573. There will be an exponential rise in people with cardiovascular risk factors. Adding to concern, in 2030, an estimated 3333 vascular surgeons will be available for 180,000,000 people with at least one risk factor for peripheral arterial disease. The paucity of properly trained surgeons entering the workforce needs to be addressed before this shortage becomes a larger burden on healthcare providers and governmental spending. © The Author(s) 2015.

The increased complexity of the decisional process in breast cancer surgery is well documented. With this study we aimed to create a software tool able to assist patients and surgeons in taking proper decisions. We hypothesized that the endpoints of breast cancer surgery could be addressed combining a set of decisional drivers. We created a decision support system software tool (DSS) and an interactive decision tree. A formal analysis estimated the information gain derived from each feature in the process. We tested the DSS on 52 patients and we analyzed the concordance of decisions obtained by different users and between the DSS suggestions and the actual surgery. We also tested the ability of the system to prevent post breast conservation deformities. The information gain revealed that patients preferences are the root of our decision tree. An observed concordance respectively of 0.98 and 0.88 was reported when the DSS was used twice by an expert operator or by a newly trained operator vs. an expert one. The observed concordance between the DSS suggestion and the actual decision was 0.69. A significantly higher incidence of post breast conservation defects was reported among patients who did not follow the DSS decision (Type III of Fitoussi, N = 4; 33.3%, p = 0.004). The DSS decisions can be reproduced by operators with different experience. The concordance between suggestions and actual decision is quite low, however the DSS is able to prevent post- breast conservation deformities. Copyright © 2016 Elsevier Ltd. All rights reserved.

The complex nature of current morbidity and mortality predictor models do not lend themselves to clinical application at the bedside of patients undergoing emergency general surgery (EGS). Our aim was to develop a simplified risk calculator for prediction of early postoperative mortality after EGS. EGS cases other than appendectomy and cholecystectomy were identified within the American College of Surgeons National Surgery Quality Improvement Program database from 2005 to 2014. Seventy-five percent of the cases were selected at random for model development, whereas 25% of the cases were used for model testing. Stepwise logistic regression was performed for creation of a 30-day mortality risk calculator. Model accuracy and reproducibility was investigated using the concordance index (c statistic) and Pearson correlations. A total of 79,835 patients met inclusion criteria. Overall, 30-day mortality was 12.6%. A simplified risk model formula was derived from five readily available preoperative variables as follows: 0.034*age + 0.8*nonindependent status + 0.88*sepsis + 1.1 (if bun ≥ 29) or 0.57 (if bun ≥18 and < 29) + 1.16 (if albumin < 2.7), or 0.61 (if albumin ≥ 2.7 and < 3.4). The risk of 30-day mortality was stratified into deciles. The risk of 30-day mortality ranged from 2% for patients in the lowest risk level to 31% for patients in the highest risk level. The c statistic was 0.83 in both the derivation and testing samples. Five readily available preoperative variables can be used to predict the 30-day mortality risk for patients undergoing EGS. Further studies are needed to validate this risk calculator and to determine its bedside applicability. Prognostic/epidemiological study, level III.

Controversy exists regarding the factors influencing the duration of work incapacity after surgically treated carpal tunnel syndrome (CTS). To determine relevant factors related to return to work. Surgical technique, clinical factors, demographic factors, other medical problems, psychosocial factors, work-related and economical factors were reviewed in patients operated on for CTS. Statistical multivariate analyses were performed to identify the baseline factors influencing the work incapacity period. A total of 107 cases were reviewed. Professional exposure to repetitive movements and heavy manual handling activity were associated with a longer return-to-work interval. The duration of work incapacity period was not significantly related to the socioprofessional category of the patient (self-employed or employee) or to the type of the procedure (open versus endoscopic surgery). Work-related features have a more important influence on return to work than personal, pathological or surgical features.

Currently, many scholars are concerned about the treatment of postoperative infection; however, few have completed multivariate analyses to determine factors that contribute to the risk of infection. Therefore, we conducted a multivariate analysis of a retrospectively collected database to analyze the risk factors for acute surgical site infection following lumbar surgery, including fracture fixation, lumbar fusion, and minimally invasive lumbar surgery. We retrospectively reviewed data from patients who underwent lumbar surgery between 2014 and 2016, including lumbar fusion, internal fracture fixation, and minimally invasive surgery in our hospital's spinal surgery unit. Patient demographics, procedures, and wound infection rates were analyzed using descriptive statistics, and risk factors were analyzed using logistic regression analyses. Twenty-six patients (2.81%) experienced acute surgical site infection following lumbar surgery in our study. The patients' mean body mass index, smoking history, operative time, blood loss, draining time, and drainage volume in the acute surgical site infection group were significantly different from those in the non-acute surgical site infection group (p operative type in the acute surgical site infection group were significantly different than those in the non-acute surgical site infection group (p operative type, operative time, blood loss, and drainage time were independent predictors of acute surgical site infection following lumbar surgery. In order to reduce the risk of infection following lumbar surgery, patients should be evaluated for the risk factors noted above.

Previous studies have shown that surgical team members' attitudes about safety and teamwork in the operating theatre may play a role in patient safety. The aim of this study was to assess attitudes about teamwork and safety among Italian surgeons and operating room nurses. Fifty-five surgeons and 48 operating room nurses working in operating theatres at one hospital in Italy completed the Operating Room Management Attitudes Questionnaire (ORMAQ). Results showed several discrepancies in attitudes about teamwork and safety between surgeons and operating room nurses. Surgeons had more positive views on the quality of surgical leadership, communication, teamwork, and organizational climate in the theatre than operating room nurses. Operating room nurses reported that safety rules and procedures were more frequently disregarded than the surgeons. The results are only partially aligned with previous ORMAQ surveys of surgical teams in other countries. The differences emphasize the influence of national culture, as well as the particular healthcare system. This study shows discrepancies on many aspects in attitudes to teamwork and safety between surgeons and operating room nurses. The findings support implementation and use of team interventions and human factor training. Finally, attitude surveys provide a method for assessing safety culture in surgery, for evaluating the effectiveness of training initiatives, and for collecting data for a hospital's quality assurance programme.

Surgeons' vigilance regarding patient condition was assessed using eye-tracking techniques during a simulated laparoscopic procedure. Surgeons were required to perform a partial cholecystectomy in a virtual reality trainer (SurgicalSim; METI Inc, Sarasota, FL) while wearing a lightweight head-mounted eye-tracker (Locarna systems Inc, Victoria, British Columbia, Canada). Half of the patients were preprogrammed to present a mildly unstable cardiac condition during the procedure. Surgical performance (evaluated by task time, instrument trajectory, and errors), mental workload (by the National Aeronautics and Space Administration Task Load Index), and eye movement were recorded and compared between 13 experienced and 10 novice surgeons. Experienced surgeons took longer to complete the task and also made more errors. The overall workload reported by surgeons was similar, but expert surgeons reported a higher level of frustration and a lower level of physical demands. Surgeon workload was greater when operating on the unstable patient than on the stable patient. Novices performed faster but focused more of their attention on the surgical task. In contrast, experts glanced more frequently at the anesthetic monitor. This study shows the usefulness of using eye-tracking technology to measure a surgeon's vigilance during an operation. Eye-tracking observations can lead to inferences about a surgeon's behavior for patient safety. The unsatisfactory performance of expert surgeons on the VR simulator suggests that the fidelity of the virtual simulator needs to improve to enable surgeons to transfer their clinical skills. This, in turn, suggests using caution when having clinical experts as instructors to teach skills with virtual simulators. Copyright © 2011 Elsevier Inc. All rights reserved.

Full Text Available Background: The choice of reconstruction options for maxillectomy defects varies significantly. Factors affecting it range from the type of defect to the surgeon's expertise. This study aims to evaluate the practice of Nigerian Oral and Maxillofacial surgeons in the reconstruction of post-maxillectomy defects. Materials and Methods: The survey was conducted by use of questionnaires administered at the annual scientific meeting of the oral and maxillofacial surgeons of Nigeria in Ibadan 2012. Results: A response rate of 66.7% was achieved. All of our respondents are consultant oral and maxillofacial surgeons, 80% of whom practice in a teaching hospital. All but one of them perform maxillectomies, however only 25% of them offer surgical reconstruction of the resulting defects to patients. Flaps have been used by 25% of the respondents, while none of them has employed microvascular reconstruction. Prosthetic rehabilitation of patients is pervasive among the respondents. Conclusion: Maxillectomy defects have far-reaching consequences on patients' quality of life and attempts should be made to reconstruct such defects. Although maxillectomy is a commonly performed procedure among oral and maxillofacial surgeons in Nigeria, especially for malignancies of the oral and paranasal sinuses, surgical reconstruction of resulting defects is not so frequently done. Microvascular surgery, which is becoming a frequently utilized option among surgeons in developed nations, is still infrequently used in our environment. There is a need for oral and maxillofacial surgeons in our climes to improve their skills so as to increase the range of reconstructive options offered.

Surgeon is sacred career. To cure patients by surgery is the surgeon's work, while the social responsibility is the surgeon's soul. To strengthen and promote the social responsibility is a demand of our age; thus, every surgeon should adhere to the supremacy of the patients' interests in clinical practice.

The aim of this study was to examine the challenges confronting surgeons performing basic science research in today's academic surgery environment. Multiple studies have identified challenges confronting surgeon-scientists and impacting their ability to be successful. Although these threats have been known for decades, the downward trend in the number of successful surgeon-scientists continues. Clinical demands, funding challenges, and other factors play important roles, but a rigorous analysis of academic surgeons and their experiences regarding these issues has not previously been performed. An online survey was distributed to 2504 members of the Association for Academic Surgery and Society of University Surgeons to determine factors impacting success. Survey results were subjected to statistical analyses. We also reviewed publicly available data regarding funding from the National Institutes of Health (NIH). NIH data revealed a 27% decline in the proportion of NIH funding to surgical departments relative to total NIH funding from 2007 to 2014. A total of 1033 (41%) members responded to our survey, making this the largest survey of academic surgeons to date. Surgeons most often cited the following factors as major impediments to pursuing basic investigation: pressure to be clinically productive, excessive administrative responsibilities, difficulty obtaining extramural funding, and desire for work-life balance. Surprisingly, a majority (68%) did not believe surgeons can be successful basic scientists in today's environment, including departmental leadership. We have identified important barriers that confront academic surgeons pursuing basic research and a perception that success in basic science may no longer be achievable. These barriers need to be addressed to ensure the continued development of future surgeon-scientists.

Pediatric surgical subspecialty workforce shortages are here to stay without any expected solution for the short-term. Individual surgeons, hospital administrators, risk management and patient-safety teams need to recognize that patient safety must take precedence over clinical productivity and financial "bottom lines." Pushing attending surgeon work hours beyond the limits of exhaustion impairs patient safety. Just as resident surgeon work hours have been appropriately curtailed in the name of patient safety, so must attending surgeon work hours. This issue needs to be addressed by hospital patient safety committees, professional societies, and by state and national regulating authorities.

Psychological factors (e.g., anxiety, depression) are routinely assessed in bariatric pre-surgical programs, as high levels of psychopathology are consistently related to poor program outcomes (e.g., failure to lose significant weight pre-surgery, weight regain post-surgery). Behavioral factors related to poor program outcomes and ways in which behavioral and psychological factors interact, have received little attention in bariatric research and practice. Potentially problematic behavioral factors are queried by Section H of the Weight and Lifestyle Inventory (WALI-H), in which respondents indicate the relevance of certain eating behaviors to obesity. A factor analytic investigation of the WALI-H serves to improve the way in which this assessment tool is interpreted and used among bariatric surgical candidates, and subsequent moderation analyses serve to demonstrate potential compounding influences of psychopathology on eating behavior factors. Bariatric surgical candidates (n =362) completed several measures of psychopathology and the WALI-H. Item responses from the WALI-H were subjected to principal axis factoring with oblique rotation. Results revealed a three-factor model including: (1) eating in response to negative affect, (2) overeating/desirability of food, and (3) eating in response to positive affect/social cues. All three behavioral factors of the WALI-H were significantly associated with measures of depression and anxiety. Moderation analyses revealed that depression did not moderate the relationship between anxiety and any eating behavior factor. Although single forms of psychopathology are related to eating behaviors, the combination of psychopathology does not appear to influence these problematic behaviors. Recommendations for pre-surgical assessment and treatment of bariatric surgical candidates are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

The American College of Surgeons Oncology Group trial Z0011 was a prospective, randomized, multicenter trial comparing overall survival between patients with positive sentinel lymph nodes (SLNs) who did and did not undergo axillary lymph node dissection (ALND). The current study compares complications associated with SLN dissection (SLND) plus ALND, versus SLND alone. From May 1999 to December 2004, 891 patients were randomly assigned to SLND + ALND (n = 445) or SLND alone (n = 446). Information on wound infection, axillary seroma, paresthesia, brachial plexus injury (BPI), and lymphedema was available for 821 patients. Adverse surgical effects were reported in 70% (278 of 399) of patients after SLND + ALND and 25% (103 of 411) after SLND alone (P alone group. At 1 year, lymphedema was reported subjectively by 13% (37 of 288) of patients after SLND + ALND and 2% (six of 268) after SLND alone (P alone. Lymphedema was more common after SLND + ALND but was significantly different only by subjective report. The use of SLND alone resulted in fewer complications.

Clinical outcomes after many complex surgical procedures vary widely across hospitals and surgeons. Although it has been assumed that the proficiency of the operating surgeon is an important factor underlying such variation, empirical data are lacking on the relationships between technical skill and postoperative outcomes. We conducted a study involving 20 bariatric surgeons in Michigan who participated in a statewide collaborative improvement program. Each surgeon submitted a single representative videotape of himself or herself performing a laparoscopic gastric bypass. Each videotape was rated in various domains of technical skill on a scale of 1 to 5 (with higher scores indicating more advanced skill) by at least 10 peer surgeons who were unaware of the identity of the operating surgeon. We then assessed relationships between these skill ratings and risk-adjusted complication rates, using data from a prospective, externally audited, clinical-outcomes registry involving 10,343 patients. Mean summary ratings of technical skill ranged from 2.6 to 4.8 across the 20 surgeons. The bottom quartile of surgical skill, as compared with the top quartile, was associated with higher complication rates (14.5% vs. 5.2%, Pbariatric surgeons varied widely, and greater skill was associated with fewer postoperative complications and lower rates of reoperation, readmission, and visits to the emergency department. Although these findings are preliminary, they suggest that peer rating of operative skill may be an effective strategy for assessing a surgeon's proficiency.

The purpose of this study was to determine the incidence of, and risk factors for, surgical site infections in a contemporary cohort of women with endometrial carcinoma. We retrospectively studied 1164 women treated for endometrial carcinoma by hysterectomy at a single institution in 2007-2013. In all, 912 women (78.4%) had minimally invasive hysterectomy. Data on surgical site infections were collected from medical records. Univariate and multivariate analyses were used to identify risk factors for incisional and organ/space infections. Ninety-four women (8.1%) were diagnosed with a surgical site infection. Twenty women (1.7%) had an incisional infection and 74 (6.4%) had an organ/space infection. The associations of 17 clinico-pathologic and surgical variables were tested by univariate analyses. Those variables that were identified as potential risk factors in univariate analyses (p infections as dependent variables. Obesity (body mass index ≥ 30 kg/m(2)), diabetes, and long operative time (>80th centile) were independently associated with a higher risk of incisional infection, whereas minimally invasive surgery was associated with a smaller risk. Smoking, conversion to laparotomy, and lymphadenectomy were associated with a higher risk of organ/space infection. Organ/space infections comprised the majority of surgical site infections. Risk factors for incisional and organ/space infections differed. Minimally invasive hysterectomy was associated with a smaller risk of incisional infections but not of organ/space infections. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

To estimate the incidence of and identify the risk factors for a surgical site infection after a cesarean section. A survey of women who underwent a cesarean section was conducted in eight hospitals in Guangdong Province, China. The rate of surgical site infection was estimated and a nested case control study was then carried out to identify the risk factors. Among 13 798 women surveyed, 96 (0.7%) developed a surgical site infection after a cesarean section. Multivariate logistic regression analysis identified six factors independently associated with an increased risk of surgical site infection, which included obesity, premature rupture of membranes, lower preoperative hemoglobin, prolonged surgery, lack of prophylactic antibiotics and excessive anal examinations performed during hospitalization. Surgical site infection occurs in approximately 0.7% of cesarean section cases in the general obstetric population in China. Obesity, premature rupture of membranes, lower preoperative hemoglobin, prolonged surgery, lack of prophylactic antibiotics and excessive anal examinations during hospitalization are considered to be independent risk factors. © 2012 The Authors.

The encounter between a patient and her surgeon is unique for several reasons. The surgeon inflicts pain upon a patient for the patient's own good. An operative intervention is irreducibly personal, such that the decisions about and performance of operations are inseparable from the idiosyncrasies of the individual surgeon. Furthermore, there is a chasm of knowledge between the patient and surgeon that is difficult to cross. Hence, training in the discipline of surgery includes the inculcation of certain virtues and practices to safeguard against abuses of this relationship and to make sure that the best interests of the patient are prioritized. The stories in this issue are evidence that in contemporary practice this is not quite enough, as surgeons reflect on instances they felt were ethically challenging. Common themes include the difficulty in communicating surgical uncertainty, patient-surgeon relationships, ethical issues in surgical training, and the impact of the technological imperative on caring for dying patients.

The relationships between industry and medical professionals are controversial. The purpose of our study was to evaluate surgeons' current opinions regarding the industry-surgery partnership, in addition to self-reported industry ties. After institutional review board approval, a survey was sent via RedCap to 3,782 surgeons across the United States. Univariate and multivariable regression analyses were performed to evaluate the responses. The response rate was 23%. From the 822 responders, 226 (27%) reported at least one current relationship with industry, while 297 (36.1%) had at least one such relationship within the past 3 years. There was no difference between general surgery versus other surgical specialties (P = .5). Among the general surgery subspecialties, respondents in minimally invasive surgery/foregut had greater ties to industry compared to other subspecialties (P = .001). In addition, midcareer surgeons, male sex, and being on a reviewer/editorial board were associated with having industry ties (P industry are important for innovation. Our study showed that relationships between surgeons and industry are common, because more than a quarter of our responders reported at least one current relationship. Industry relations are perceived as necessary for operative innovation. Copyright © 2017 Elsevier Inc. All rights reserved.

Articular cartilage lesions have a direct effect on the success of surgical treatment. The aim of this study was to determine the prevalence rate, location, grade, and factors associated with acetabular rim articular cartilage lesions in patients undergoing hip arthroscopy. A prospective study was conducted by analysing the intraoperative data of 152 hips in 122 patients treated with hip arthroscopy for femoroacetabular impingement from January 2011 to May 2016. The prevalence rate, location, and grade were calculated, as well as the pre-operative factors associated with acetabular rim articular cartilage lesions. The mean age of the patients was 38.6 years. The Tönnis grade was 0 in 103 hips, and 1 in 52 hips. Acetabular rim articular cartilage lesions were present in 109 (70.3%) hips. The location of the lesions was superior-anterior. Independent risk factors for the presence of acetabular rim articular cartilage lesions were an alpha-angle equal or greater than 55°, duration of symptoms equal or greater than 20 months, and Tegner activity scale level equal or greater than 6. Although patients were classified as Tönnis grade 0 and 1, and 3tesla MRI reported acetabular lesions in 1.3% of cases, there was a high frequency of acetabular rim cartilage lesions. Knowledge of the independent risk factors associated with acetabular rim articular cartilage lesions may assist the orthopaedic surgeon with the decision to perform hip arthroscopy.

To determine prognostic indicators for the surgical treatment of brachycephalic obstructive airway syndrome (BOAS) and to compare the prognosis of 2 multilevel surgical procedures. Prospective clinical study. Client-owned pugs, French bulldogs, and bulldogs (n = 50). Noninvasive whole-body barometric plethysmography (WBBP) was used to assess respiratory function before, 1 month and 6 months after upper airway corrective surgery. Postoperatively, BOAS indices (ie, ascending severity score generated from WBBP data, 0%-100%) that equaled to or exceeded the cut-off values of BOAS in the diagnostic models were considered to have a "poor prognosis." A multivariate logistic regression was used to assess predictors for prognosis. The median BOAS indices decreased after surgery (from 76% to 63%, P dogs with indices in this range would still be considered clinically affected. Age (odds ratios [OR] = 0.96, 95% confidence interval [CI]: 0.93-0.99, P dogs with a higher probability of poor prognosis. © 2017 The American College of Veterinary Surgeons.

To identify risk factors associated with surgical wound infection in patients infected with human immunodeficiency virus (HIV) undergoing surgery for orthopaedic trauma. Records of 29 male and 7 female HIV-positive patients aged 18 to 47 years who underwent surgery for orthopaedic trauma were reviewed. Data on HIV-specific variables (HIV clinical classification, CD4+ lymphocyte count) and highly active antiretroviral therapy were retrieved, as were data on wound class, fracture type, surgery type, surgical wound infections, and outcomes. Possible risk factors associated with surgical wound infection were analysed. The median follow-up period was 27 (range, 19-41) months. Of the 36 patients, 14 (39%) developed surgical wound infections (4 were deep and 10 superficial). 89% and 67% of them were in HIV clinical category B and in CD4+ T-lymphocyte category 3, respectively. 12 of these infections resolved after debridement and prolonged antibiotic treatment, and 2 developed chronic osteomyelitis. Four of the patients had non-union. Surgical wound infections were associated with HIV clinical category B (pwounds (p=0.003). Identification of risk factors may help minimise morbidity in HIV-positive patients.

Full Text Available ABSTRACT OBJECTIVE: To analyze infections of the surgical site among patients undergoing clean-wound surgery for correction of femoral fractures. METHODS: This was a historical cohort study developed in a large-sized hospital in Belo Horizonte. Data covering the period from July 2007 to July 2009 were gathered from the records in electronic medical files, relating to the characteristics of the patients, surgical procedures and surgical infections. The risk factors for infection were identified by means of statistical tests on bilateral hypotheses, taking the significance level to be 5%. Continuous variables were evaluated using Student'sttest. Categorical variables were evaluated using the chi-square test, or Fisher's exact test, when necessary. For each factor under analysis, a point estimate and the 95% confidence interval for the relative risk were obtained. In the final stage of the study, multivariate logistic regression analysis was performed. RESULTS: 432 patients who underwent clean-wound surgery for correcting femoral fractures were included in this study. The rate of incidence of surgical site infections was 4.9% and the risk factors identified were the presence of stroke (odds ratio, OR = 5.0 and length of preoperative hospital stay greater than four days (OR = 3.3. CONCLUSION: To prevent surgical site infections in operations for treating femoral fractures, measures involving assessment of patients' clinical conditions by a multiprofessional team, reduction of the length of preoperative hospital stay and prevention of complications resulting from infections will be necessary.

Acute septic arthritis in a native joint may require more than one surgical debridement to eradicate the infection. Our objectives were to determine the prevalence of failure of a single surgical debridement for acute septic arthritis, to identify risk factors for failure of a single debridement, and to develop a prognostic probability algorithm to predict failure of a single surgical debridement for acute septic arthritis in adults. We collected initial laboratory and medical comorbidity data of 128 adults (132 native joints) with acute septic arthritis who underwent at least one surgical debridement at our institution between 2000 and 2011. Univariate and logistic regression analyses were used to identify potential risk factors for failure of a single surgical debridement. Stepwise variable selection was used to develop a prediction model and identify probabilities of failure of a single surgical debridement. Of the 128 patients (132 affected joints) who underwent surgical debridement for acute septic arthritis, forty-nine (38%) of the patients (fifty joints) experienced failure of a single debridement and required at least two debridements (range, two to four debridements). Staphylococcus aureus was the most common bacterial isolate (in sixty, or 45%, of the 132 joints). Logistic regression analysis identified five independent clinical predictors for failure of a single surgical debridement: a history of inflammatory arthropathy (odds ratio [OR], 7.3; 95% confidence interval [CI], 2.4 to 22.6; p 85.0 x 10(9) cells/L (OR, 4.7; 95% CI, 1.8 to 17.7; p = 0.002), S. aureus as the bacterial isolate (OR, 4.6; 95% CI, 1.8 to 11.9; p = 0.002), and a history of diabetes (OR, 2.6; 95% CI, 1.1 to 6.2; p = 0.04). Most (62%) of the septic joints were managed effectively with a single surgical debridement. Adults with a history of inflammatory arthropathy, involvement of a large joint, a synovial-fluid nucleated cell count of >85.0 x 10(9) cells/L, an infection with S. aureus

Cesarean Section (CS) is one of the most commonly performed surgical procedures in obstetrical and gynecological department. Surgical site infection (SSI) after a cesarean section increases maternal morbidity prolongs hospital stay and medical costs. The aim of this study was to find out the incidence and associated risk factors of surgical site infection among cesarean section cases. A prospective, descriptive study was conducted at Dhulikhel Hospital, department of Obstetrics and Gynaecology from July 2013 to June 2014. Total of 648 women who underwent surgical procedure for delivery during study period were included in the study. Data was collected from patient using structred pro forma and examination of wound till discharge was done. Data was compared in terms of presence of surgical site infection and study variables. Wound was evaluated for the development of SSI on third day, and fifth post-operative day, and on the day of discharge. Total of 648 cases were studied. The mean age was 24±4.18. Among the studied cases 92% were literate and 8% were illiterate. Antenatal clinic was attended by 97.7%. The incidence rate of surgical site infection was 82 (12.6%). SSI was found to be common in women who had rupture of membrane before surgery (p=0.020), who underwent emergency surgery (p=0.0004), and the women who had vertical skin incision (p=0.0001) and interrupted skin suturing (p=0.0001) during surgery. Surgical site infection following caesarean section is common. Various modifiable risk factors were observed in this study. Development of SSI is related to multifactorial rather than one factor. Development and strict implementation of protocol by all the health care professionals could be effective to minimize and prevent the infection rate after caesarean section.

The rate of cesarean delivery is increasing in North America. Surgical site infection following this operation can make it difficult to recover, care for a baby and return home. We aimed to determine the incidence of surgical site infection to 30 days following cesarean delivery, associated risk factors and whether risk factors differed for predischarge versus postdischarge infection. We identified a retrospective cohort in Nova Scotia by linking the provincial perinatal database to hospital admissions and physician billings databases to follow women for 30 days after they had given birth by cesarean delivery between Jan. 1, 1997 and Dec. 31, 2012. Logistic regression with generalized estimating equations was used to determine risk factors for infection. A total of 25 123 women had 33 991 cesarean deliveries over the study period. Of the 25 123, 923 had surgical site infections, giving an incidence rate of 2.7% (95% CI 2.54%-2.89%); the incidence decreased over time. Risk factors for infection (adjusted odds ratios ≥ 1.5) were prepregnancy weight 87.0 kg or more, gaining 30.0 kg or more during pregnancy, chorioamnionitis, maternal blood transfusion, anticoagulation therapy, alcohol or drug abuse, second stage of labour before surgery, delivery in 1997-2000 and delivery in a hospital performing 130-1249 cesarean deliveries annually. Women who gave birth earlier in the study period, those who gave birth in a hospital with 130-949 cesarean deliveries per year and those with more than 1 fetus were at a significantly higher risk for surgical site infection before discharge; women who smoked were at significantly higher risk for surgical site infection after discharge. Most risk factors are known before delivery, and some are potentially modifiable. Although the incidence of surgical site infection decreased over time, targeted clinical and infection prevention and control interventions could further reduce the burden of illness associated with this health

Philosophers know that modern philosophy owes a great debt to the intellectual contributions of the 18th century philosopher Immanuel Kant. This essay attempts to show how cosmetic surgeons, and all surgeons at that, could learn much from his work. Not only did Kant write about the structure of human reasoning and how it relates to appearances but he also wrote about the nature of duties and other obligations. His work has strongly influenced medical ethics. In a more particular way, Kant wrote the most important work on aesthetics. His theory still influences how philosophers understand the meaning of the beautiful and how it pertains to the human figure. This essay presents an exercise in trying to apply Kantian philosophy to aesthetic plastic surgery. Its intention is to show cosmetic surgeons some of the implicit and explicit philosophical principles and potential arguments undergirding their potential surgical evaluations. It is meant to challenge the surgeon to reconsider how decisions are made using philosophical reasoning instead of some of the more usual justifications based on psychology or sociology.

Although numerous leadership development programs (LDPs) exist in health care, no programs have been specifically designed to meet the needs of surgeons. This study aimed to elicit practicing surgeons' motivations and desired goals for leadership training to design an evidence-based LDP in surgery. At a large academic health center, we conducted semistructured interviews with 24 surgical faculty members who voluntarily applied and were selected for participation in a newly created LDP. Transcriptions of the interviews were analyzed using analyst triangulation and thematic coding to extract major themes regarding surgeons' motivations and perceived needs for leadership knowledge and skills. Themes from interview responses were then used to design the program curriculum specifically to meet the leadership needs of surgical faculty. Three major themes emerged regarding surgeons' motivations for seeking leadership training: (1) Recognizing key gaps in their formal preparation for leadership roles; (2) Exhibiting an appetite for personal self-improvement; and (3) Seeking leadership guidance for career advancement. Participants' interviews revealed four specific domains of knowledge and skills that they indicated as desired takeaways from a LDP: (1) leadership and communication; (2) team building; (3) business acumen/finance; and (4) greater understanding of the health care context. Interviews with surgical faculty members identified gaps in prior leadership training and demonstrated concrete motivations and specific goals for participating in a formal leadership program. A LDP that is specifically tailored to address the needs of surgical faculty may benefit surgeons at a personal and institutional level. Copyright © 2016 Elsevier Inc. All rights reserved.

Retrospective cohort analysis of prospectively collected clinical data. To compare outcomes of elective spine fusion and laminectomy when performed by neurological and orthopedic surgeons. The relationship between primary specialty training and outcome of spinal surgery is unknown. We analyzed the 2006 to 2012 American College of Surgeons National Surgical Quality Improvement Project database of 50,361 patients, 33,235 (66%) of which were operated on by a neurosurgeon. We eliminated all differences in preoperative and intraoperative risk factors between surgical specialties by matching 17,126 patients who underwent orthopedic surgery (OS) to 17,126 patients who underwent neurosurgery (NS) on propensity scores. Regular and conditional logistic regressions were used to predict adverse postoperative outcomes in the full sample and matched sample, respectively. The effect of perioperative transfusion on outcomes was further assessed in the matched sample. Diagnosis and procedure were the only factors that were found to be significantly different between surgical subspecialties in the full sample. We found that compared with patients who underwent NS, patients who underwent OS were more than twice as likely to experience prolonged length of stay (LOS) (odds ratio: 2.6, 95% confidence interval: 2.4-2.8), and significantly more likely to receive a transfusion perioperatively, have complications, and to require discharge with continued care. After matching, patients who underwent OS continued to have slightly higher odds for prolonged LOS, and twice the odds for receiving perioperative transfusion compared with patients who underwent NS. Taking into account perioperative transfusion did not eliminate the difference in LOS between patients who underwent OS and those who underwent NS. Patients operated on by OS have twice the odds for undergoing perioperative transfusion and slightly increased odds for prolonged LOS. Other differences between surgical specialties in 30-day

Surgical site infection (SSI) complicates approximately 2% of surgeries in the Veterans Affairs (VA) hospitals. Surgical site infections are responsible for increased morbidity, length of hospital stay, cost, and mortality. Surgical site infection can be minimized by modifying risk factors. In this study, we identified risk factors and developed accurate predictive surgical specialty-specific SSI risk prediction models for the Veterans Health Administration (VHA) surgery population. In a retrospective observation study, surgical patients who underwent surgery from October 2013 to September 2016 from 136 VA hospitals were included. The Veteran Affairs Surgical Quality Improvement Program (VASQIP) database was used for the pre-operative demographic and clinical characteristics, intra-operative characteristics, and 30-day post-operative outcomes. The study population represents 11 surgical specialties: neurosurgery, urology, podiatry, otolaryngology, general, orthopedic, plastic, thoracic, vascular, cardiac coronary artery bypass graft (CABG), and cardiac valve/other surgery. Multivariable logistic regression models were developed for the 30-day post-operative SSIs. Among 354,528 surgical procedures, 6,538 (1.8%) had SSIs within 30 days. Surgical site infection rates varied among surgical specialty (0.7%-3.0%). Surgical site infection rates were higher in emergency procedures, procedures with long operative duration, greater complexity, and higher relative value units. Other factors associated with increased SSI risk were high level of American Society of Anesthesiologists (ASA) classification (level 4 and 5), dyspnea, open wound/infection, wound classification, ascites, bleeding disorder, chemotherapy, smoking, history of severe chronic obstructive pulmonary disease (COPD), radiotherapy, steroid use for chronic conditions, and weight loss. Each surgical specialty had a distinct combination of risk factors. Accurate SSI risk-predictive surgery specialty

Emergency general surgery (EGS) contributes to half of all surgical mortality nationwide, is associated with a 50% complication rate, and has a 15% readmission rate within 30 days. We assessed associations between surgeon and hospital EGS volume with these outcomes. Using Maryland's Health Services Cost Review Commission database, we identified nontrauma EGS procedures performed by general surgeons among patients 20 years or older, who were admitted urgently or emergently, from July 2012 to September 2014. We created surgeon and hospital volume categories, stratified EGS procedures into simple (mortality ≤ 0.5%) and complex (>0.5%) procedures, and assessed postoperative mortality, complications, and 30-day readmissions. Multivariable logistic regressions both adjusted for clinical factors and accounted for clustering by individual surgeons. We identified 14,753 procedures (61.5% simple EGS, 38.5% complex EGS) by 252 (73.3%) low-volume surgeons (≤25 total EGS procedures/year), 63 (18.3%) medium-volume surgeons (26 to 50/year), and 29 (8.4%) high-volume surgeons (>50/year). Low-volume surgeons operated on one-third (33.1%) of all patients. For simple procedures, the very low rate of death (0.2%) prevented a meaningful regression with mortality; however, there were no associations between low-volume surgeons and complications (adjusted odds ratio [aOR] 1.07; 95% CI 0.81 to 1.41) or 30-day readmissions (aOR 0.80; 95% CI 0.64 to 1.01) relative to high-volume surgeons. Among complex procedures, low-volume surgeons were associated with greater mortality (aOR 1.64; 95% CI 1.12 to 2.41) relative to high-volume surgeons, but not complications (aOR 1.06; 95% CI 0.85 to 1.32) or 30-day readmission (aOR 0.99; 95% CI 0.80 to 1.22). Low-volume hospitals (≤125 total EGS procedures/year) relative to high-volume hospitals (>250/year) were not associated with mortality, complications, or 30-day readmissions for simple or complex procedures. We found evidence that surgeon EGS

Open surgery continues to have a fundamental role in urology, and one of its main complications is surgical wound infection. Our objective was to analyse surgical wound infection in patients who underwent surgery in our Department of Urology and to assess the risk factors, microorganisms and resistances by type of surgery. This was a prospective observational study that included 940 patients: 370 abdominal/open lumbar surgeries and 570 genitoperineal surgeries. We analysed age, sex, comorbidities, stay and type of surgery, as well as the causal microorganisms and antibiotic resistances. For genitoperineal surgery, we found 15 cases (2.6%) of surgical wound infection associated with previous urinary catheterisation. Most of the isolated microorganisms corresponded to enterobacteriaceae, highlighting the resistance to beta-lactam. In abdominal/lumbar surgery, we found 41 cases (11.1%) of surgical wound infection. The incidence rate was 3.3% in prostate surgery; 9.8% in renal surgery; and 45.0% in cystectomy. Heart disease was associated with a higher incidence rate of surgical wound infection. The most common microorganisms were Enterococcus spp. (27.1%), E.coli (22.9%) and Staphylococcus aureus (14.6%). Enterococcus and beta-lactamase-producing E.coli are resistant to ampicillin in 37.5% and 41.7% of cases, respectively. We found a low incidence rate of surgical wound infection in genitoperineal surgery, compared with renal surgery and cystectomy. The presence of heart disease and carrying a previous urinary catheter are factors associated with surgical wound infection. Enterococcus and E.coli are the most common pathogens, with high rates of resistance. Copyright © 2016 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

When present sciatica is considered an obstacle to recovery in low back pain patients, yet evidence is limited regarding prognostic factors for persistent disability in this patient group. The aim of this study is to describe and summarise the evidence regarding prognostic factors for sciatica in non-surgically treated cohorts. Understanding the prognostic factors in sciatica and their relative importance may allow the identification of patients with particular risk factors who might benefit from early or specific types of treatment in order to optimise outcome. A systematic literature search was conducted using Medline, EMBASE and CINAHL electronic databases. Prospective cohort studies describing subjects with sciatica and measuring pain, disability or recovery outcomes were included. Studies of cohorts comprised entirely of surgically treated patients were excluded and mixed surgically and conservatively treated cohorts were included only if the results were analysed separately by treatment group or if the analysis was adjusted for treatment. Seven adequate or high quality eligible studies were identified. There were conflicting but mainly negative results regarding the influence of baseline pain severity, neurological deficit, nerve root tension signs, duration of symptoms and radiological findings on outcome. A number of factors including age, gender, smoking, previous history of sciatica and heaviness of work do not appear to influence outcome. In contrast to studies of low back pain and purely surgically treated sciatica cohorts, psychological factors were rarely investigated. At present, the heterogeneity of the available studies makes it difficult to draw firm conclusions about sciatica prognosis, and highlights the need for further research for this group of patients. Large scale prospective studies of high methodological quality, using a well-defined, consistent definition of sciatica and investigating psychosocial factors alongside clinical and

To determine the factors that affect sleep status of surgical and medical patients during hospitalisation. This hospital-based, cross-sectional study was conducted at Karadeniz Technical University's Farabi Hospital, Trabzon, Turkey, from July to October 2014. Data was gathered using a questionnaire and the Form of Factors Affecting Sleep Pattern. SPSS 15 was used for statistical analysis. Of the 184 participants, there were 92(50%) each from the surgery and medical clinics. The mean score for the Form of Factors Affecting Sleep Pattern was 84.57±8.65 among the surgical patients and 78.01±17.61 among the medical patients. It was found that noise at the hospital affected sleep patterns among 73(79.3%) of the surgical patients and among 64(69.6%) of the medical patients. There were statistically significant differences between mean scores of the surgical patients and gender and marital status (p=0.001 and p=0.012, respectively), whereas among the medical patients statistically significant differences existed between mean scores and having operation (p=0.09). Both groups of patients underwent changes in sleep routines during hospitalisation.

Background Surgical education remains an important mission of academic medical centers. Financial pressures, however, may favor improved operating room (OR) efficiency at the expense of surgical education. We aim to characterize resident impact on the duration of procedural time using common pediatric otolaryngologic cases which do not necessitate a surgical assistant and assess whether other factors modify the extent to which residents impact OR efficiency. Study Design We retrospectively reviewed resident and attending surgeon total OR and procedural times for isolated tonsillectomy, adenoidectomy, tonsillectomy with adenoidectomy (T&A) and bilateral myringotomy with tube insertion between 2009 and 2013. We included cases supervised or performed by one of four teaching surgeons in children with ASA < 3. Regression analyses were used to identify predictors of procedural time. Results We identified a total of 3,922 procedures. Residents had significantly longer procedure times for all four procedures compared to an attending surgeon (range: 4.9 to 12.8 minutes, p<0.001). These differences were proportional to case complexity. When comparing mean procedural times, similar differences between the resident surgeon and attending surgeon cohorts were appreciated (p<0.0001). In T&A patients, older patient age, and attending surgeon identity were also significant predictors of increased mean procedural time (p<0.05). Conclusions Resident participation contributes to increased procedure time for common otolaryngology procedures. While residents may increase operative times, addressing other system-wide issues may decrease impact of time needed for education and added efficiencies of resident participation may exist throughout the perioperative period. Our model is applicable to surgical education across specialties. Level of Evidence 4 PMID:25251257

Delayed neurological deterioration following mild head injury(MHI)usually occurs within 24 hours. However, some cases require delayed surgical evacuation of an acute subdural hematoma(ASDH), owing to subacute progressive hematoma enlargement. This study aimed to determine radiological or clinical parameters associated with surgical intervention in ASDH cases in which surgery was not initially considered necessary. From 2010 to 2015, 64 patients were non-surgically treated for ASDH following MHI. We evaluated the various outcomes of eventual surgical ASDH evacuation after the first 48 hours following injury, due to hematoma enlargement and clinical deterioration. Univariate and multivariate analyses were applied to both the demographic and initial radiographic features to identify risk factors for ASDH progression and surgery. Overall, at the time of their last follow-up computed tomography, 57 patients(89%)demonstrated minimal ASDH or spontaneous hematoma resolution with conservative non-surgical management. The remaining 7 patients(11%)received delayed surgical ASDH evacuation a median of 5.1 days after the head trauma. There were no significant differences between the two groups for baseline characteristics, including age, prior history of anticoagulants, the presence of cerebral contusions, or subarachnoid hemorrhages. On multivariate analysis, use of antiplatelet drugs(p=0.013, OR=28, 95%CI=1.82-24)was independently associated with delayed hematoma evacuation. These data indicate that as much as 11% of patients with minimal ASDHs after MHI can deteriorate over the course of a week and then require surgical intervention, and that patients on concurrent antiplatelet medication require especially careful monitoring of hematoma progression.

One of the most central collaborative tasks during surgical operations is the passing of objects, including instruments. Little is known about how nurses and surgeons achieve this. The aim of the present study was to explore what factors affect this routine-like task, resulting in fast or slow transfer of objects. A qualitative video study, informed by an observational ethnographic approach, was conducted in a major teaching hospital in the UK. A total of 20 general surgical operations were observed. In total, approximately 68 h of video data have been reviewed. A subsample of 225 min has been analysed in detail using interactional video-analysis developed within the social sciences. Two factors affecting object transfer were observed: (1) relative instrument trolley position and (2) alignment. The scrub nurse's instrument trolley position (close to vs. further back from the surgeon) and alignment (gaze direction) impacts on the communication with the surgeon, and consequently, on the speed of object transfer. When the scrub nurse was standing close to the surgeon, and "converged" to follow the surgeon's movements, the transfer occurred more seamlessly and faster (1.0 s). The smoothness of object transfer can be improved by adjusting the scrub nurse's instrument trolley position, enabling a better monitoring of surgeon's bodily conduct and affording early orientation (awareness) to an upcoming request (changing situation). Object transfer is facilitated by the surgeon's embodied practices, which can elicit the nurse's attention to the request and, as a response, maximise a faster object transfer. A simple intervention to highlight the significance of these factors could improve communication in the operating theatre. Copyright © 2014 Elsevier Ltd. All rights reserved.
Full Text Available CONTEXT: Risk factors for failure of trabeculectomy may have a cumulative effect on the outcome. AIMS: To study the effect of preoperative ocular risk factors on the surgical outcome of trabeculectomy augmented with 2 commonly used doses of Mitomycin C. SETTINGS AND DESIGN: In a prospective cohort study, cases were recruited over an 18 month period. 92 eyes of 83 patients with one to three known risk factors for failure of trabeculectomy underwent Mitomycin-C (MMC augmented trabeculectomy. METHODS AND MATERIAL: Trabeculectomy was done with a randomly chosen MMC dose of 0.2 mg/ml or 0.4 mg/ml. All cases were followed up for a period of at least 3 months. Surgical success was defined as the lowering of intraocular pressure (IOP below 21 mmHg during the follow up period. STATISTICAL ANALYSIS USED: Chi square test, paired t test, odds ratio, effect size. RESULTS: Eyes with two or three risk factors (out of aphakic glaucoma, failed trabeculectomy, neovascular glaucoma, post uveitic glaucoma, traumatic glaucoma, adherent leucoma, juvenile glaucoma, prolonged medical therapy, steroid induced glaucoma, post penetrating keratoplasty glaucoma and developmental glaucoma had a significantly poorer surgical success rate (88% and 78% than eyes with one risk factor (100%. 0.4 mg/ml MMC used sub-sclerally had a statistically similar effect on lowering the IOP as 0.2 mg/ml in all groups. The rate of complications was significantly higher in the 0.4 mg/ml subgroup. CONCLUSIONS: The presence of more than one preoperative ocular risk factor, affects the surgical success of MMC augmented trabeculectomy in high-risk cases. Because of the significantly higher rate of complications with the higher dose of MMC, this should be used sparingly, only in cases with more than two risk factors.

Full Text Available Laparoscopic distal pancreatectomy (LDP is a safe and reliable treatment for tumors in the body and tail of the pancreas. Postoperative pancreatic fistula (POPF is a common complication of pancreatic surgery. Despite improvement in mortality, the rate of POPF still remains high and unsolved. To identify risk factors for POPF after laparoscopic distal pancreatectomy, clinicopathological variables on 120 patients who underwent LDP with stapler closure were retrospectively analyzed. Univariate and multivariate analyses were performed to identify risk factors for POPF. The rate of overall and clinically significant POPF was 30.8% and13.3%, respectively. Higher BMI (≥25kg/m2 (p-value = 0.025 and longer operative time (p-value = 0.021 were associated with overall POPF but not clinically significant POPF. Soft parenchymal texture was significantly associated with both overall (p-value = 0.012 and clinically significant POPF (p-value = 0.000. In multivariable analyses, parenchymal texture (OR, 2.933, P-value = 0.011 and operative time (OR, 1.008, P-value = 0.022 were risk factors for overall POPF. Parenchymal texture was an independent predictive factor for clinically significant POPF (OR, 7.400, P-value = 0.001.

Children with hydrocephalus are at risk for epilepsy both due to their underlying condition and as a consequence of surgical treatment; however, the relative contributions of these factors remain unknown. The authors sought to characterize epilepsy among children with infancy-onset hydrocephalus and to examine the risks of epilepsy associated with hydrocephalus subtype and with factors related to surgical treatment. We conducted a longitudinal cohort study of all children with infancy-onset hydrocephalus treated at a major regional children's hospital during 2002 to 2012, with follow-up to ascertain risk factors and epilepsy outcome through April 2015. Poisson regression was used to calculate adjusted risk ratios and 95% confidence intervals for associations. Among 379 children with hydrocephalus, 86 (23%) developed epilepsy (mean onset age = 2.7 years), almost one fifth of whom had a history of infantile spasms. Relative to spina bifida-associated hydrocephalus, children with other major hydrocephalus subtypes had fourfold higher risks of developing epilepsy. Among children who underwent surgery, surgical infection doubled the risk of epilepsy (risk ratio = 2.0, 95% confidence interval = 1.4 to 3.0). Epilepsy was associated with surgical failure for intracranial reasons but not extracranial reasons (risk ratio = 1.7, 95% confidence interval = 1.1 to 2.7; risk ratio = 1.1, 95% confidence interval = 0.7 to 1.9, respectively). Epilepsy is common among children with hydrocephalus. Compared with children with spina bifida-associated hydrocephalus, children with other major hydrocephalus subtypes have a markedly increased risk of epilepsy. Surgical infection doubles the risk of epilepsy. Copyright © 2016 Elsevier Inc. All rights reserved.

Retrospective cohort study. The purpose of this study was to assess the rate of blood transfusion after cervical fusion surgery, and its effect on complication rates. Cervical spine fusions have gained interest in the literature since these procedures are now ever more frequently being performed in an outpatient setting with few complications. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients that underwent cervical fusion from 2010 to 2013. Multivariate regression analysis was used to determine postoperative complications associated with transfusion and cervical fusion. We identified 11,588 patients who had cervical fusion between 2010 and 2013. The rate of blood transfusion following cervical fusion found to be 1.47%. All transfused patients were found to have increased risk of venous thromboembolism (TBE) (odds ratio [OR], 3.19; 95% confidence interval [95% CI], 1.16-8.77), myocardial infarction (MI) (OR, 9.12; 95% CI, 2.53-32.8), increased length of stay (LOS) (OR, 28.03; 95% CI, 14.28-55.01) and mortality (OR, 4.14; 95% CI, 1.44-11.93). Single level fusion had increased risk of TBE (OR, 3.37; 95% CI, 1.01-11.33), MI (OR, 10.5; 95% CI, 1.88-59.89), and LOS (OR, 14.79; 95% CI, 8.2-26.67). Multilevel fusion had increased risk of TBE (OR, 5.64; 95% CI, 1.15-27.6), surgical site infection (OR, 16.29; 95% CI, 3.34-79.49), MI (OR, 10.84; 95% CI, 2.01-58.55), LOS (OR, 26.56; 95% CI, 11.8-59.78), and mortality (OR, 10.24; 95% CI, 2.45-42.71). Patients who had anterior cervical discectomy and fusion surgery and received a transfusion had an increased risk of TBE (OR, 4.87; 95% CI, 1.04-22.82), surgical site infection (OR, 9.73; 95% CI, 2.14-44.1), MI (OR, 9.88; 95% CI, 1.87-52.2), increased LOS of more than 2 days (OR, 28.34; 95% CI, 13.79-58.21) and increase in mortality (OR, 6.3; 95% CI, 1.76-22.48). While, transfused patients who had posterior fusion surgery had increased risk of MI (OR

Prospective multicenter database. To identify factors associated with outcomes from adolescent idiopathic scoliosis (AIS) surgery outcomes and especially poor results. Because AIS is rarely symptomatic during adolescence, excellent surgical results are expected. However, some patients have poor outcomes. This study seeks to identify factors correlating with results and especially those making poor outcomes more likely. Demographic, surgical, and radiographic parameters were compared to 2-year postoperative Scoliosis Research Society (SRS) scores in 477 AIS surgical patients using stepwise linear regression to identify factors predictive of 2-year domain and total scores. Poor postoperative score patients (>2 SD below mean) were compared using t tests to those with better results. The SRS instrument exhibited a strong ceiling effect. Two-year scores showed more improvement with greater curve correction (self-image, pain, and total), and were worse with larger body mass index (pain, mental, total), larger preoperative trunk shift (mental and total), larger preoperative Cobb (self-image), and preoperative symptoms (function). Poor results were more common in those with Lenke 3 curve pattern (pain), less preoperative coronal imbalance, trunk shift and rib prominence (function), preoperative bracing (self-image), and anterior procedures (mental). Poor results also had slightly less average curve correction (50% vs. 60%) and larger curve residuals (31° vs. 23°). Complications, postoperative curve magnitude, and instrumentation type did not significantly contribute to postoperative scores, and no identifiable factors contributed to satisfaction. Curve correction improves patient's self-image whereas pain and poor function before surgery carry over after surgery. Patients with less spinal appearance issues (higher body mass index, Lenke 3 curves) are less happy with their results. Except in surgical patient selection, many of these factors are beyond physician control.

A recurrent lumbar disc herniation (RLDH) is the most prevalent cause for new radicular pain after surgery for disc herniation-induced sciatica. Reported risk factors include age, gender and smoking, while its surgical treatment is associated to a higher rate of complications and costs. The purpose of this study is to identify factors that increase the risk of requiring surgical treatment for a first RLDH in workers' compensation patients. Nested case-control: 109 patients operated for an RLDH (cases) between June 1st 1994 and May 31st 2011 (minimum follow-up 1 year) and 109 randomly selected patients operated for a first disc herniation with no recurrence during the study period (controls). Age, gender, smoking status, type of work and MRI characteristics of the index herniation were statistically evaluated as potential risk factors. Patient's age of less than 35 years (p = 0.001) and a subligamentous herniation (p disc herniation and patient's age inferior to 35 years at the time of the first surgery are risk factors for requiring surgical treatment of a first RLDH among workers' compensation patients.

There are limited data regarding the available pediatric surgical workforce in South Africa and their employment prospects on completion of their specialist training. This aim of this study was to quantify and analyze the pediatric surgical workforce in South Africa as well as to determine their geographic and sector distribution. This involved a quantitative descriptive analysis of all registered specialist as well as training pediatric surgeons in South Africa. The results showed 2.6 pediatric surgeons per one million population under 14 years. More than half (69%) were male and the median age was 46.8 years. There were however, more female surgical registrars currently in training. The majority of the pediatric surgical practitioners were found in Gauteng, followed by the Western Cape and Kwa-Zulu Natal. The majority of specialists reportedly worked in the public sector, however the number of public sector pediatric surgeons available to those without health insurance fell below those available to private patients. Interprovincial differences as well as intersectoral differences were marked indicating geographic and socioeconomic maldistribution of pediatric surgeons. Addressing this maldistribution requires concerted efforts to expand public sector specialist posts. Descriptive audit LEVEL OF EVIDENCE: IV. Copyright © 2018 Elsevier Inc. All rights reserved.

The objective of this study was to assess the factors associated with anatomical and visual outcomes in patients presenting with Acanthamoeba keratitis (AK). This is a retrospective noncomparative interventional case series study comprising 44 eyes from 42 patients presenting with AK, treated with topical hexamidine diisethionate and topical polyhexamethylene biguanide, monitored between 2004 and 2008. AK was confirmed by polymerase chain reaction or direct microscopic examination. Correlation between clinical presentation and prognosis was assessed. Anatomical outcome was assessed according to the percentage of eyes requiring at least 1 surgical procedure in addition to topical treatment. Visual outcome was assessed by the best-corrected visual acuity at the end of follow-up. Polymerase chain reaction results were positive for Acanthamoeba in 40 of the 44 eyes (91%) and in 16 of the 44 eyes (36%) by direct microscopic examination. Confocal microscopy suggested the presence of Acanthamoeba in 12 of 19 eyes (63%). Amniotic membrane transplantation was performed in 8 eyes, penetrating keratoplasty in 4 eyes, and evisceration in 2 eyes. The average follow-up time was 10 months. Surgical treatment was significantly associated (P 30 days, an initial visual acuity of ≤20/200, an infiltrate size of >3 mm, preperforating infiltrates, and corneal neovascularization. The average final visual acuity was 20/48 in eyes that did not require surgical treatment (n = 34) and 20/1702 in eyes that required at least 1 surgical procedure (n = 10; P < 0.0001). Late diagnosis, low initial visual acuity, corneal neovascularization, large infiltrates, and preperforated infiltrates were associated with surgical treatment in patients presenting with AK. Surgical intervention was associated with worse visual outcome.

Since the days of Sushruta, innovation has shaped the history of plastic surgery. Plastic surgeons have always been known as innovators or close followers of innovations. With this descriptive international survey study, the authors aimed to evaluate the future of plastic surgeons by analyzing how plastic surgery and plastic surgeons will be affected by new trends in medicine. Aesthetic surgery is the main subclass of plastic surgery thought to be the one that will change the most in the future. Stem cell therapy is considered by plastic surgeons to be the most likely "game changer." Along with changes in surgery, plastic surgeons also expect changes in plastic surgery education. The most approved assumption for the future of plastic surgery is, "The number of cosmetic nonsurgical procedures will increase in the future." If surgeons want to have better outcomes in their practice, they must at least be open minded for innovations if they do not become innovators themselves. Besides the individual effort of each surgeon, international and local plastic surgery associations should develop new strategies to adopt these innovations in surgical practice and education.

A state of the art surgical training is crucial for the attraction of surgery as a medical profession. The German surgical community can only succeed in overcoming the shortage of young surgeons by the development of an attractive and professional training environment. Responsibility for surgical training has to be taken by the heads of department as well as by the surgical societies. Good surgical training should be deemed to be part of the corporate strategy of German hospitals and participation in external courses has to be properly funded by the hospital management. On the other hand residents are asked for commitment and flexibility and should keep records in logbooks and take part in assessment projects to gain continuing feedback on their learning progress. The surgical community is in charge of developing a structured but flexible training curriculum for each of the eight surgical training trunks. A perfect future curriculum has to reflect and cross-link local hospital training programs with a central training portfolio of a future Academy of German Surgeons, such as workshops, courses and e-learning projects. This challenge has to be dealt with in close cooperation by all surgical boards and societies. A common sense of surgery as a community in diversity is crucial for the success of this endeavour.

Despite the significant contribution of surgical spending to health care costs, most surgeons are unaware of their operating room costs. To examine the association between providing surgeons with individualized cost feedback and surgical supply costs in the operating room. The OR Surgical Cost Reduction (OR SCORE) project was a single-health system, multihospital, multidepartmental prospective controlled study in an urban academic setting. Intervention participants were attending surgeons in orthopedic surgery, otolaryngology-head and neck surgery, and neurological surgery (n = 63). Control participants were attending surgeons in cardiothoracic surgery, general surgery, vascular surgery, pediatric surgery, obstetrics/gynecology, ophthalmology, and urology (n = 186). From January 1 to December 31, 2015, each surgeon in the intervention group received standardized monthly scorecards showing the median surgical supply direct cost for each procedure type performed in the prior month compared with the surgeon's baseline (July 1, 2012, to November 30, 2014) and compared with all surgeons at the institution performing the same procedure at baseline. All surgical departments were eligible for a financial incentive if they met a 5% cost reduction goal. The primary outcome was each group's median surgical supply cost per case. Secondary outcome measures included total departmental surgical supply costs, case mix index-adjusted median surgical supply costs, patient outcomes (30-day readmission, 30-day mortality, and discharge status), and surgeon responses to a postintervention study-specific health care value survey. The median surgical supply direct costs per case decreased 6.54% in the intervention group, from $1398 (interquartile range [IQR], $316-$5181) (10 637 cases) in 2014 to $1307 (IQR, $319-$5037) (11 820 cases) in 2015. In contrast, the median surgical supply direct cost increased 7.42% in the control group, from $712 (IQR, $202-$1602) (16 441 cases

Identification of prognostic factors for surgery in patients with sciatica is important to be able to predict surgery in an early stage. Identification of prognostic factors predicting persistent pain, disability and recovery are important for better understanding of the clinical course, to inform patient and physician and support decision making. Consequently, we aimed to systematically review prognostic factors predicting outcome in non-surgically treated patients with sciatica. A search of Medline, Embase, Web of Science and Cinahl, up to March 2012 was performed for prospective cohort studies on prognostic factors for non-surgically treated sciatica. Two reviewers independently selected studies for inclusion and assessed the risk of bias. Outcomes were pain, disability, recovery and surgery. A best evidence synthesis was carried out in order to assess and summarize the data. The initial search yielded 4392 articles of which 23 articles reporting on 14 original cohorts met the inclusion criteria. High clinical, methodological and statistical heterogeneity among studies was found. Reported evidence regarding prognostic factors predicting the outcome in sciatica is limited. The majority of factors that have been evaluated, e.g., age, body mass index, smoking and sensory disturbance, showed no association with outcome. The only positive association with strong evidence was found for leg pain intensity at baseline as prognostic factor for subsequent surgery. © 2013 European Federation of International Association for the Study of Pain Chapters.

ABSTRACT Glaucoma is a multifactorial condition under serious influence of many risk factors. The role of diabetes mellitus (DM) in glaucoma etiology or progression remains inconclusive. Although, the diabetic patients have different healing mechanism comparing to the general population and it has a possible-negative role on surgical outcomes. This review article attempts to analyze the association of both diseases, glaucoma and DM, before and after the surgery. The epidemiological studies, b...

and distributed electronically via e-mail to a total of 1253 members of The Danish Society of Surgeons and The Danish Society of Young Surgeons. RESULTS: In total, 352 (approximately 30%) surgeons completed the questionnaire, 54.4% were over 50 years of age, and 76.6% were men. When choosing surgery, the most...... important factors taken into consideration were the risk of complication and short convalescence, whereas the least important factors were cosmesis and option of local anaesthesia. If the surgeons themselves were to undergo cholecystectomy, 35.5% would choose SILS, and 14.5% would choose NOTES provided...... become standard techniques for cholecystectomy within 6 years. CONCLUSIONS: The importance of risk of complications has not surprisingly a high priority among surgeons in this questionnaire. Why this is has to be investigated further before implementing SILS and NOTES as standard of care....
Mandatory lessons in anatomy, taught by the praelector anatomiae (lecturer in anatomy) of the Amsterdam Guild of Surgeons, were an important part of the surgical training starting in the 16th century. We describe how surgeons were trained approximately 350 years ago at the Surgeons’ Guild. The role
In more complicated cases of cloacal malformation, advanced imaging in the form of MRI or 3D fluoroscopy is valuable. In the South African setting, 2D fluoroscopy with the surgeon present is adequate to help in planning for the surgical management. Communication between the radiologist and paediatric surgeon is ...

The clinical outcome of patients with oncologic emergencies is often poor and mortality is high. It is important to determine which patients may benefit from invasive treatment, and for whom conservative treatment and/or palliative care would be appropriate. In this study, prognostic factors for clinical outcome are identified in order to facilitate the decision-making process for patients with surgical oncologic emergencies. This was a prospective registration study for patients over 18 years of age, who were consulted for surgical oncologic emergencies between November 2013 and April 2014. Multiple variables were registered upon emergency consultation, and the follow-up period was 90 days. Multivariate logistic regression analysis was performed to identify factors associated with 30- and 90-day mortality. During the study period, 207 patients experienced surgical oncologic emergencies-101 (48.8 %) men and 106 (51.2 %) women, with a median age of 64 years (range 19-92). The 30-day mortality was 12.6 % and 90-day mortality was 21.7 %. Factors significantly associated with 30-day mortality were palliative intent of cancer treatment prior to emergency consultation (p = 0.006), Eastern Cooperative Oncology Group performance score (ECOG-PS) >0 (p for trend: p = 0.03), and raised lactate dehydrogenase (LDH) (p surgical oncologic emergencies. Additional measurements of HGS, LDH, and albumin levels can serve as objective parameters to support the clinical assessment of individual prognosis.

A journal impact factor represents the mean number of citations per article published. Designed as one tool to measure the relative importance of a journal, impact factors are often incorporated into academic evaluation of investigators. The authors sought to determine how impact factors of emergency medicine (EM) journals compare to journals from other medical and surgical specialties and if any change has taken place over time. The 2010 impact factors and 5-year impact factors for each journal indexed by the Thomson Reuters ISI Web of Knowledge Journal Citation Reports (JCR) were collected, and EM, medical, and surgical specialties were evaluated. The maximum, median, and interquartile range (IQR) of the current impact factor and 5-year impact factor in each journal category were determined, and specialties were ranked according to the summary statistics. The "top three" impact factor journals for each specialty were analyzed, and growth trends from 2001 through 2010 were examined with random effects linear regression. Data from 2,287 journals in 31 specialties were examined. There were 23 EM journals with a current maximum impact factor of 4.177, median of 1.269, and IQR of 0.400 to 2.176. Of 23 EM journals, 57% had a 5-year impact factor available, with a maximum of 4.531, median of 1.325, and IQR of 0.741 to 2.435. The top three EM journals had a mean standard deviation (±SD) impact factor of 3.801 (±0.621) and median of 4.142 and a mean (±SD) 5-year impact factor of 3.788 (±1.091) and median of 4.297, with a growth trend of 0.211 (95% confidence interval [CI] = 0.177 to 0.245; p journals ranked no higher than 24th among 31 specialties. Emergency medicine journals rank low in impact factor summary statistics and growth trends among 31 medical and surgical specialties. © 2012 by the Society for Academic Emergency Medicine.

Casualties in military conflict produce patterns of injuries that are not seen in routine surgical practice at home. In an era of increasing surgical sub-specialization the deployed surgeon needs to acquire and maintain a wide range of skills from a variety of surgical specialties. Improvised explosive devices (IEDs) have become the modus operandi for terrorists and in the current global security situation these tactics can be equally employed against civilian targets. Therefore, knowledge and training in the management of these injuries are relevant to both military and civilian surgeons. To create this kind of military surgeon the so-called "DUO-plus" model for the training of surgical officers (specialization general surgery plus a second specialization either in visceral surgery or orthopedics/trauma surgery) has been developed in the Joint Medical Service of the German Bundeswehr. Other relevant skills, such as emergency neurotraumatology, battlefield surgery with integrated oral and craniomaxillofacial surgery and emergency gynecology, are integrated into this concept and will be taught in courses. Log books will be kept in accordance with the training curricula. On successful completion of the program medical officers will be officially appointed as Medical Officer "Einsatzchirurg" by their commanding officers for a maximum of 5 years and it will be necessary to renew it after this period. These refresher programs will require participation in visiting physicians programs in the complementary surgical disciplines in order to retain the essential specific skills.

The "best" operation in the setting of acute complicated diverticulitis has been debated for decades. Multiple studies, including a recent prospective randomized trial, have reported improved outcomes with primary anastomosis. The aim of this study was to determine whether surgeon or patient-specific factors drives the choice of operative procedure. Consecutive adult patients with sigmoid diverticulitis, requiring emergent operative treatment for acute complicated diverticulitis, from 1997 to 2012 at an academic medical center, were identified from a prospectively maintained complications database. Patient characteristics, surgeon, choice of operation, and outcomes including postoperative complications and stoma reversal were noted. The use of primary anastomosis and associated outcomes between colorectal and noncolorectal surgeons were compared. There were 151 patients who underwent urgent resection during the study period, and 136 met inclusion criteria. Eighty-two resections (65.1%) were performed by noncolorectal surgeons and 44 by colorectal surgeons (34.9%). Noncolorectal surgeons performed more Hartmann procedures (68.3% vs 40.9%, p = 0.01) despite similar demographics, American Society of Anesthesiologists (ASA) classification, and Hinchey stage. Length of stay, time to stoma reversal, ICU days, and postoperative complications were lower in the colorectal group (43.2% vs 16.7, p = 0.02). Although patient-specific factors are important, surgeon is a potent predictor of operation performed in the setting of severe acute diverticulitis. A more aggressive approach to primary anastomosis may lower the complication rate after surgical treatment for severe acute diverticulitis. Copyright © 2014 American College of Surgeons.

This study aims to investigate the current opinion of gastroenterologists and surgeons on treatment strategies for patients, with recurrences or ongoing complaints of diverticulitis. Treatment of recurrences and ongoing complaints remains a point of debate. No randomized trials have been published yet and guidelines are not uniform in their advice. A web-based survey was conducted among gastroenterologists and GE-surgeons. Questions were aimed at the treatment options for recurrent diverticulitis and ongoing complaints. In total, 123 surveys were filled out. The number of patients with recurrent or ongoing diverticulitis who were seen at the outpatient clinic each year was 7 (0-30) and 5 (0-115) respectively. Surgeons see significantly more patients on an annual basis 20 vs. 15% (p = 0.00). Both surgeons and gastroenterologists preferred to treat patients in a conservative manner using pain medication and lifestyle advise (64.4 vs. 54.0, p = 0.27); however, gastroenterologists would treat patients with mesalazine medication, which is significantly more (28%, p = 0.04) than in the surgical group. Surgeons are inclined more towards surgery (31.5%, p = 0.02). Both surgeons and gastroenterologists prefer to treat recurrent diverticulitis and ongoing complaints in a conservative manner. Quality of life, the risk of complications and the viewpoint of the patient are considered important factors in the decision to resect the affected colon. © 2016 S. Karger AG, Basel.

This study aimed to identify and compare risk factors for surgical site infection (SSI) and non-surgical site infections (non-SSIs), particularly urinary tract infection (UTI), after spine surgery. We retrospectively reviewed 825 patients (median age 59.0 years (range 33-70 years); 442 males) who underwent spine surgery at Kagoshima University Hospital from January 2009 to December 2014. Patient parameters were compared using the Mann-Whitney U and Fisher's exact tests. Risk factors associated with SSI and UTI were analyzed via the multiple logistic regression analysis. P operation time (P = 0.0019 and 0.0162, respectively) and ASA classification 3 (P = 0.0132 and 0.0356, respectively). The 1 week post-operative C-reactive protein (CRP) level was a risk factor for UTI (P = 0.0299), but not for SSI (P = 0.4996). There was no relationship between SSI and symptomatic UTI after spine surgery. Risk factors for post-operative SSI and UTI were operative time and ASA classification 3; 1 week post-operative CRP was a risk factor for UTI only.
Full Text Available Background: In surgeries of closed calcaneal fractures, the lateral L-shaped incision is usually adopted. Undesirable post-operative healing of the incision is a common complication. In this retrospective study, controllable risk factors of incision complications after closed calcaneal fracture surgery through a lateral L-shaped incision are discussed and the effectiveness of clinical intervention is assessed. Materials and Methods: A review of medical records was conducted of 209 patients (239 calcaneal fractures surgically treated from June 2005 to October 2012. Univariate analyses were performed of seven controllable factors that might influence complications associated with the surgical incision. Binomial multiple logistic regression analysis was performed to determine factors of statistical significance. Results: Twenty-one fractures (8.79% involved surgical incision complications, including 8 (3.35% cases of wound dehiscence, 7 (2.93% of flap margin necrosis, 5 (2.09% of hematoma, and 1 (0.42% of osteomyelitis. Five factors were statistically significant : t0 he time from injury to surgery, operative duration, post-operative drainage, retraction of skin flap, bone grafting, and patients′ smoking habits. The results of multivariate analyses showed that surgeries performed within 7 days after fracture, operative time > 1.5 h, no drainage after surgery, static skin distraction, and patient smoking were risk factors for calcaneal incision complications. The post-operative duration of antibiotics and bone grafting made no significant difference. Conclusion: Complications after calcaneal surgeries may be reduced by postponing the surgery at least 7 days after fracture, shortening the time in surgery, implementing post-operative drainage, retracting skin flaps gently and for as short a time as possible, and prohibiting smoking.

Surgeons must demonstrate leadership to optimize performance and maximize patient safety in the operating room, but no behavior rating tool is available to measure leadership. Ten focus groups with members of the operating room team discussed surgeons' intraoperative leadership. Surgeons' leadership behaviors were extracted and used to finalize the Surgeons' Leadership Inventory (SLI), which was checked by surgeons (n = 6) for accuracy and face validity. The SLI was used to code video recordings (n = 5) of operations to test reliability. Eight elements of surgeons' leadership were included in the SLI: (1) maintaining standards, (2) managing resources, (3) making decisions, (4) directing, (5) training, (6) supporting others, (7) communicating, and (8) coping with pressure. Interrater reliability to code videos of surgeons' behaviors while operating using this tool was acceptable (κ = .70). The SLI is empirically grounded in focus group data and both the leadership and surgical literature. The interrater reliability of the system was acceptable. The inventory could be used for rating surgeons' leadership in the operating room for research or as a basis for postoperative feedback on performance. Copyright © 2013 Elsevier Inc.

Rural bypass for elective surgical procedures is a challenge for critical access hospitals, yet there are opportunities for rural hospitals to improve local retention of surgical candidates through alternative approaches to developing surgery lines of business. In this study we examine the effect of visiting surgical specialists on the odds of rural bypass. Discharge data from the 2011 State Inpatient Databases and State Ambulatory Surgery Databases for Iowa were linked to outreach data from the Office of Statewide Clinical Education Programs and Iowa Physician Information System to model the effect of surgeon specialist supply on rural patients' decision to bypass rural critical access hospitals. Patients in rural communities with a local general surgeon were more likely to be retained in a community than to bypass. Those in communities with visiting general surgeons were more likely to bypass, as were those in communities with visiting urologists and obstetricians. Patients in communities with visiting ophthalmologists and orthopedic surgeons were at higher odds of being retained for their elective surgeries. In addition to known patient and local hospital factors that have an influence on bypass behavior among rural patients seeking elective surgery, availability of surgeon specialists also plays an important role in whether patients bypass or not. Visiting ophthalmologists and orthopedic surgeons were associated with less bypass, as was having local general surgeons. Visiting general surgeons, urologists, and obstetricians were associated with greater odds of bypass. © 2016 National Rural Health Association.

The rate of surgical site infections (SSI) and their associated risk factors was identified by performing postdischarge surveillance following cesarean section at a public university teaching hospital in Brazil. The study was conducted at the Center for Women's Integrated Health Care in Brazil between May 2008 and March 2009. Women were contacted by telephone 15 and 30 days after cesarean section. During hospitalization, a form was completed on factors associated with post-cesarean SSI. The chi(2) test and Fisher exact test were used to analyze categorical variables and the Mann-Whitney test for numerical variables. Relative risks (RR) and their respective 95% confidence intervals (95% CI) were calculated for factors associated with SSI. P values cesarean section SSI. A 15-day postdischarge follow-up was shown to be sufficient. Hypertension was a factor associated with SSI. Copyright 2010 Association for Professionals in Infection Control and Epidemiology, Inc.

To reduce the incidence of urinary tract infection, Surgical Care Improvement Project 9 mandates the removal of urinary catheters within 48 hours postoperatively. In patients with thoracic epidural anesthesia, we sought to determine the rate of catheter reinsertion, the complications of reinsertion, and the factors associated with reinsertion. We conducted a prospective observational study of consecutive patients undergoing major pulmonary or esophageal resection with thoracic epidural analgesia over a 2-year period. As per Surgical Care Improvement Project 9, all urinary catheters were removed within 48 hours postoperatively. Excluded were patients with chronic indwelling catheter, patients with urostomy, and patients requiring continued strict urine output monitoring. Multivariable logistic regression analysis was used to identify independent risk factors for urinary catheter reinsertion. Thirteen patients met exclusion criteria. Of the 275 patients evaluated, 60 (21.8%) required reinsertion of urinary catheter. There was no difference in the urinary tract infection rate between patients requiring reinsertion (1/60 [1.7%]) versus patients not requiring reinsertion (1/215 [0.5%], P = .389). Urethral trauma during reinsertion was seen in 1 of 60 patients (1.7%). After reinsertion, discharge with urinary catheter was required in 4 of 60 patients (6.7%). Multivariable logistic regression analysis found esophagectomy, lower body mass index, and benign prostatic hypertrophy to be independent risk factors associated with catheter reinsertion after early removal in the presence of thoracic epidural analgesia. When applying Surgical Care Improvement Project 9 to patients undergoing thoracic procedures with thoracic epidural analgesia, consideration to delayed removal of urinary catheter may be warranted in patients with multiple risk factors for reinsertion.

Task (over-)load imposed on surgeons is a main contributing factor to surgical errors. Recent research has shown that gaze metrics represent a valid and objective index to asses operator task load in non-surgical scenarios. Thus, gaze metrics have the potential to improve workplace safety by providing accurate measurements of task load variations. However, the direct relationship between gaze metrics and surgical task load has not been investigated yet. We studied the effects of surgical task complexity on the gaze metrics of surgical trainees. We recorded the eye movements of 18 surgical residents, using a mobile eye tracker system, during the performance of three high-fidelity virtual simulations of laparoscopic exercises of increasing complexity level: Clip Applying exercise, Cutting Big exercise, and Translocation of Objects exercise. We also measured performance accuracy and subjective rating of complexity. Gaze entropy and velocity linearly increased with increased task complexity: Visual exploration pattern became less stereotyped (i.e., more random) and faster during the more complex exercises. Residents performed better the Clip Applying exercise and the Cutting Big exercise than the Translocation of Objects exercise and their perceived task complexity differed accordingly. Our data show that gaze metrics are a valid and reliable surgical task load index. These findings have potential impacts to improve patient safety by providing accurate measurements of surgeon task (over-)load and might provide future indices to assess residents' learning curves, independently of expensive virtual simulators or time-consuming expert evaluation.

To determine the incidence of burnout among American surgeons and evaluate personal and professional characteristics associated with surgeon burnout. : Burnout is a syndrome of emotional exhaustion and depersonalization that leads to decreased effectiveness at work. A limited amount of information exists about the relationship between specific demographic and practice characteristics with burnout among American surgeons. Members of the American College of Surgeons (ACS) were sent an anonymous, cross-sectional survey in June 2008. The survey evaluated demographic variables, practice characteristics, career satisfaction, burnout, and quality of life (QOL). Burnout and QOL were measured using validated instruments. Of the approximately 24,922 surgeons sampled, 7905 (32%) returned surveys. Responders had been in practice 18 years, worked 60 hours per week, and were on call 2 nights/wk (median values). Overall, 40% of responding surgeons were burned out, 30% screened positive for symptoms of depression, and 28% had a mental QOL score >1/2 standard deviation below the population norm. Factors independently associated with burnout included younger age, having children, area of specialization, number of nights on call per week, hours worked per week, and having compensation determined entirely based on billing. Only 36% of surgeons felt their work schedule left enough time for personal/family life and only 51% would recommend their children pursue a career as a physician/surgeon. Burnout is common among American surgeons and is the single greatest predictor of surgeons' satisfaction with career and specialty choice. Additional research is needed to identify individual, organizational, and societal interventions that preserve and promote the mental health of American surgeons.

If a skeletal anterior open bite malocclusion is treated by orthognathic surgery directed only at the mandible, the lower jaw is repositioned upward in a counter-clockwise rotation. However, this procedure has a high risk of relapse. In the present study, the key factors associated with post-surgical stability of corrected skeletal anterior open bite malocclusions were investigated. Eighteen orthognathic patients were subjected to cephalometric analysis to assess the dental and skeletal changes following mandibular surgery for the correction of an anterior open bite. The patients were divided into two groups, determined by an increase or decrease in nasion-menton (N-Me) distance as a consequence of surgery. Changes in overbite, the displacements of molars and positional changes in Menton were evaluated immediately before and after surgery and after a minimum of one year post-operatively. The group with a decreased N-Me distance exhibited a significantly greater backward positioning of the mandible. The group with an increased N-Me distance experienced significantly greater dentoalveolar extrusion of the lower molars. A sufficient mandibular backward repositioning is an effective technique in the prevention of open bite relapse. In addition, it is important not to induce molar extrusion during post-surgical orthodontic treatment to preserve stability of the surgical open bite correction.

Keeping patients safe is a core nursing duty. The dynamic nature of the healthcare environment requires that nurses practice to the full extent of their education, experience, and role to keep patients safe. Research has focused on error causation rather than error recovery, a process that occurs before patient harm ensues. In addition, little is known about the role nurses play in error recovery. A descriptive cross-sectional, correlational study using a sample of 184 nurses examined relationships between nurse characteristics, organizational factors, and recovery of medical errors among medical-surgical nurses in hospitals. In this article, we provide background information to introduce the concept of error recovery, and present our study aims and methods. Study results suggested that medical-surgical nurses recovered on average 22 medical errors and error recovery was positively associated with education and expertise. The discussion section further considers the important role of medical-surgical nurses and error recovery to enhance patient safety. In conclusion, we suggest that creating a safer healthcare system will depend on the ability of nurses to fully use their education, expertise and role to identify, interrupt, and correct medical errors; thereby, preventing patient harm.

Two hundred and forty-eight patients with urethral stricture underwent different surgical interventions: internal optical urethrotomy (IOU for strictures of different portions of the urethra in 157 patients (the operation was made once in 121 patients, twice in 24 patients, and thrice or more in 12; replacement urethroplasty using a buccal mucosa graft for strictures of the anterior urethra in 46 patients; Turner-Warwick’s anastomotic urethroplasty modified by Webster for strictures (distraction defects of the posterior urethra in 45 patients. The results of surgical treatment were studied using urethrography, uroflowmetry, urethrocystoscopy, the international prostate symptom score, quality of life (QoL questionnaire, and the international index of erectile function (IIEF questionnaire. The role of risk factors for postoperative recurrent urethral stricture was assessed by univariate and multivariate analyses.Results. The rate of recurrent urethral stricture after IOU was 66.9 % (59.5, 87.5, and 100 % after the first, second, third or more subsequent operations, respectively; 12.1 % after all types of urethroplasty, 15.2 % after augmentation urethroplasty, and 8.9 % after anastomotic urethroplasty. The major risk factors of recurrent urethral stricture after IOU were recognized to be the location of urethral stricture in the penile or bulbomembranous portions, a urethral stricture length of > 1 cm, severe urethral lumen narrowing, and performance of 2 or more operations; those after augmentation urethroplasty were previous ineffective treatment, a stricture length of > 4 cm, lichen sclerosus, and smoking; those after anastomotic urethroplasty were previous ineffective treatment, smoking, and a stricture length of > 4 cm.Conclusion.

Wound condition after primary total knee arthroplasty (TKA) is an important issue to avoid any postoperative adverse events. Our purpose was to investigate and to clarify the important surgical factors affecting wound score after TKA. A total of 139 knees in 128 patients (mean 73 years) without severe comorbidity were enrolled in the present study. All primary unilateral or bilateral TKAs were done using the same skin incision line, measured resection technique, and wound closure technique using unidirectional barbed suture. In terms of the wound healing, Hollander Wound Evaluation Score (HWES) was assessed on postoperative day 14. We performed multiple regression analysis using stepwise method to identify the factors affecting HWES. Variables considered in the analysis were age, sex, body mass index (kg/m(2)), HbA1C (%), femorotibial angle (degrees) on plain radiographs, intraoperative patella eversion during the cutting phase of the femur and the tibia in knee flexion, intraoperative anterior translation of the tibia, patella resurfacing, surgical time (min), tourniquet time (min), length of skin incision (cm), postoperative drainage (ml), patellar height on postoperative lateral radiographs, and HWES. HWES was treated as a dependent variable, and others were as independent variables. The average HWES was 5.0 ± 0.8 point. According to stepwise forward regression test, patella eversion during the cutting phase of the femur and the tibia in knee flexion and anterior translation of the tibia were entered in this model, while other factors were not entered. Standardized partial regression coefficient was as follows: 0.57 in anterior translation of the tibia and 0.38 in patella eversion. Fortunately, in the present study using the unidirectional barbed suture, major wound healing problem did not occur. As to the surgical technique, intraoperative patella eversion and anterior translation of the tibia should be avoided for quality cosmesis in primary TKA.

In the absence of a defined retirement age, academic surgeons need to develop plans for transition as they approach the end of their academic surgical careers. The development of a plan for late career transition represents an opportunity for departments of surgery across Canada to initiate a constructive process in cooperation with the key stakeholders in the hospital or institution. The goal of the process is to develop an individual plan for each faculty member that is agreeable to the academic surgeon; informs the surgical leadership; and allows the late career surgeon, the hospital, the division and the department to make plans for the future. In this commentary, the literature on the science of aging is reviewed as it pertains to surgeons, and guidelines for late career transition planning are shared. It is hoped that these guidelines will be of some value to academic programs and surgeons across the country as late career transition models are developed and adopted.

Surgical site infection is one of the most common complications following ankle fracture surgery. These infections are associated with substantial morbidity and lead to increased resource utilization. Identification of risk factors is crucial for developing strategies to prevent these complications. We performed an age and sex-matched case-control study to identify patient and surgery-related risk factors for deep surgical site infection following operative ankle fracture treatment. We identified 1923 ankle fracture operations performed in 1915 patients from 2006 through 2009. A total of 131 patients with deep infection were identified and compared with an equal number of uninfected control patients. Risk factors for infection were determined with use of conditional logistic regression analysis. The incidence of deep infection was 6.8%. Univariate analysis showed diabetes (odds ratio [OR] = 2.2, 95% confidence interval [CI] = 1.0, 4.9), alcohol abuse (OR = 3.8, 95% CI = 1.6, 9.4), fracture-dislocation (OR = 2.0, 95% CI = 1.2, 3.5), and soft-tissue injury (a Tscherne grade of ≥1) (OR = 2.6, 95% CI = 1.3, 5.3) to be significant patient-related risk factors for infection. Surgery-related risk factors were suboptimal timing of prophylactic antibiotics (OR = 1.9, 95% CI = 1.0, 3.4), difficulties encountered during surgery, (OR = 2.1, 95% CI = 1.1, 4.0), wound complications (OR = 4.8, 95% CI = 1.6, 14.0), and fracture malreduction (OR = 3.4, 95% CI = 1.3, 9.2). Independent risk factors for infection identified by multivariable analyses were tobacco use (OR = 3.7, 95% CI = 1.6, 8.5) and a duration of surgery of more than ninety minutes (OR = 2.5, 95% CI = 1.1, 5.7). Cast application in the operating room was independently associated with a decreased infection rate (OR = 0.4, 95% CI = 0.2, 0.8). We identified several modifiable risk factors for deep surgical site infection following operative treatment of ankle fractures.

BACKGROUND: The number of cholecystectomies required to be fully educated as a surgeon has not yet been established. The European Association for Endoscopic Surgery, however, claims that inadequate experience is a risk factor for bile duct injury. The objective was to investigate surgical...... experience as a risk factor after laparoscopic cholecystectomy. METHODS: A prospective cohort study using the Danish Cholecystectomy Database to generate a cohort including adults treated with laparoscopic cholecystectomy from 2006 to 2011. The relationship between surgeons' level of experience and outcomes...... were evaluated. RESULTS: Surgical inexperience was not a risk factor for mortality and morbidity. The risk of conversion was however higher when the patients were operated by more experienced surgeons with an odds ratio of 1.80 (95% confidence interval, 1.51-2.14). Surgical inexperience was not a risk...

The Australian and New Zealand Audit of Surgical Mortality (ANZASM) is a nationwide confidential peer review of deaths associated with surgical care. This study assesses the concordance between treating surgeons and peer reviewers in reporting clinical events and delays in management. This is a retrospective cross-sectional analysis of deaths in 2009 and 2010. Cases that went through the process of submission of details by the surgeon in a structured surgical case form (SCF), first-line assessment (FLA) and a more detailed second-line assessment (SLA) were included. Significant clinical events reported for these patients were categorized and analysed for concordance. Of the 11,303 notifications of death to the ANZASM, 6507 (57.6%) were audited and 685 (10.5%) required the entire review process. Nationally, the most significant events were post-operative complications, poor preoperative assessment and delay to surgery or diagnosis. The SCF submissions reported 338 events, as compared with 1009 and 985 events reported through FLA and SLA, respectively (P = 0.01). Treating surgeons and assessors attributed 29-30% of events to factors outside the surgeon's control. Surgeons felt that delay to surgery or diagnosis was a significant event in 6.6% of cases, in contrast to 20% by assessors (P = 0.01). Preoperative management could be improved in 19% of cases according to surgeons, compared with 45 and 36% according to the assessors (P audit process. © 2014 Royal Australasian College of Surgeons.

Ruptured cerebral aneurysm is a life-threatening condition that requires urgent medical attention. In Malaysia, a prospective study by the Umum Sarawak Hospital, Neurosurgical Center, in the year 2000-2002 revealed an average of two cases of intracranial aneurysms per month with an operative mortality of 20% and management mortality of 25%. Failure to diagnose, delay in admission to a neurosurgical centre, and lack of facilities could have led to the poor surgical outcome in these patients. The purpose of this study is to identify the factors that significantly predict the outcome of patients undergoing a surgical clipping of ruptured aneurysm in the local population. A single center retrospective study with a review of medical records was performed involving 105 patients, who were surgically treated for ruptured intracranial aneurysms in the Sultanah Aminah Hospital, in Johor Bahru, from July 2011 to January 2016. Information collected was the patient demographic data, Glasgow Coma Scale (GCS) prior to surgery, World Federation of Neurosurgical Societies Scale (WFNS), subarachnoid hemorrhage (SAH) grading system, and timing between SAH ictus and surgery. A good clinical grade was defined as WFNS grade I-III, whereas, WFNS grades IV and V were considered to be poor grades. The outcomes at discharge and six months post surgery were assessed using the modified Rankin's Scale (mRS). The mRS scores of 0 to 2 were grouped into the "favourable" category and mRS scores of 3 to 6 were grouped into the "unfavourable" category. Only cases of proven ruptured aneurysmal SAH involving anterior circulation that underwent surgical clipping were included in the study. The data collected was analysed using the Statistical Package for Social Sciences (SPSS). Univariate and multivariate analyses were performed and a P -value of < 0.05 was considered to be statistically significant. A total of 105 patients were included. The group was comprised of 42.9% male and 57.1% female patients

In the past decade there has been a remarkable increase in the number of patients having cosmetic operations to achieve a more youthful appearance. Demographic, social and economic factors in our society have contributed to this phenomenon, along with an increase in the number of trained plastic surgeons. Moreover, there recently have been major technical advances in aesthetic surgical procedures, including innovations in anesthetic techniques. The newer procedures for forehead-plasty, blepha...

Surgeons' non-technical skills are an important part of surgical performance and surgical education. The most widely adopted assessment tool is the Non-Technical Skills for Surgeons (NOTSS) behaviour rating system. Psychometric analysis of this tool to date has focused on inter-rater reliability and feasibility rather than validation. NOTSS assessments were collected from two groups of consultant/attending surgeons in the UK and USA, who rated behaviours of the lead surgeon during a video-based simulated crisis scenario after either online or classroom instruction. The process of validation consisted of assessing construct validity, scale reliability and concurrent criterion validity, and undertaking a sensitivity analysis. Central to this was confirmatory factor analysis to evaluate the structure of the NOTSS taxonomy. Some 255 consultant surgeons participated in the study. The four-category NOTSS model was found to have robust construct validity evidence, and a superior fit compared with alternative models. Logistic regression and sensitivity analysis revealed that, after adjusting for technical skills, for every 1-point increase in NOTSS score of the lead surgeon, the odds of having a higher versus lower patient safety score was 2·29 times. The same pattern of results was obtained for a broad mix of surgical specialties (UK) as well as a single discipline (cardiothoracic, USA). The NOTSS tool can be applied in research and education settings to measure non-technical skills in a valid and efficient manner. © 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.

A cesarean section is a surgical procedure in which incisions are made through a woman's abdomen and uterus to deliver her baby. Surgical site infections are a common surgical complication among patients delivered with cesarean section. Further it caused to increase maternal morbidity, stay of hospital and the cost of treatment. Hospital based cross-sectional study was conducted to assess the magnitude of surgical site infection following cesarean Site Infections and its associated factors at Lemlem Karl hospital July 1, 2013 to June 30, 2016. Retrospective card review was done on 384 women who gave birth via cesarean section at Lemlem Karl hospital from July 1, 2013 to June 30, 2016. Systematic sampling technique was used to select patient medical cards. The data were entered by Epi info version 7.2 then analyzed using Statistical Package for Social Sciences windows version 20. Both bivariate and multivariate logistic regression was done to test association between predictors and dependent variables. P value of cesarean section, the magnitude of surgical site infection following cesarean section Infection was 6.8%. The identified independent risk factors for surgical site infections were the duration of labor AOR=3.48; 95%CI (1.25, 9.68), rupture of membrane prior to cesarean section AOR=3.678; 95%CI (1.13, 11.96) and the abdominal midline incision (AOR=5.733; 95%CI (2.05, 16.00). The magnitude of surgical site infection following cesarean section is low compare to other previous studies. The independent associated factors for surgical site infection after cesarean section in this study: Membranes rupture prior to cesarean section, duration of labor and sub umbilical abdominal incision. In addition to ensuring sterile environment and aseptic surgeries, use of WHO surgical safety checklist would appear to be a very important intervention to reduce surgical site infections.

We analyzed factors associated with early recovery of continence after laparoscopic radical prostatectomy. Among 467 patients treated with laparoscopic radical prostatectomy for localized prostate cancer between 2007 and 2012, 249 patients who underwent a preoperative urodynamic study were enrolled. The patients' age, prostate volume, preoperative serum prostate-specific antigen (PSA), Gleason score, pathologic stage, and preoperative urodynamic parameters were recorded. The preoperative membranous and prostatic urethral length on magnetic resonance image, nerve sparing technique, and type of surgical procedure (extrafascial and intrafascial) were analyzed. Patients were considered to have early recovery of continence when they needed no pad in 3 months or less after surgery. Ninety-two patients were in the early recovery group and 157 were in the late recovery group. The membranous urethral lengths were 12.06±2.56 and 11.81±2.87 mm, and prostatic urethral lengths were 36.39±6.15 and 37.45±7.55 mm in each group, respectively. The membranous-posterior urethral length ratios were 0.25±0.06 and 0.24±0.06, and prostatic-posterior urethral length ratios were 0.75±0.06 and 0.76±0.06, respectively. In and of themselves, the membranous and prostatic urethral lengths were not associated with recovery duration however, the membranous-total and prostatic-total urethral length ratios were related (p=0.024 and 0.024, respectively). None of the urodynamic parameters correlated with continence recovery time. In the multivariate analysis, the type of surgical procedure (odds ratio [OR], 7.032; 95% confidence interval [CI], 2.660 to 18.590; precovery of continence. The current intrafascial surgical procedure is the most important factor affecting early recovery of continence after laparoscopic radical prostatectomy.

Turnaround time of laboratory results is important for customer satisfaction. The College of American Pathologists' checklist requires an analytic turnaround time of 2 days or less for most routine cases and lets every hospital define what a routine specimen is. The objective of this study was to analyze which factors impact turnaround time of nonbiopsy surgical pathology specimens. We calculated the turnaround time from receipt to verification of results (adjusted for weekends and holidays) for all nonbiopsy surgical specimens during a 2-week period. Factors studied included tissue type, number of slides per case, decalcification, immunohistochemistry, consultations with other pathologists, and diagnosis. Univariate and multivariate analyses were performed. A total of 713 specimens were analyzed, 551 (77%) were verified within 2 days and 162 (23%) in 3 days or more. Lung, gastrointestinal, breast, and genitourinary specimens showed the highest percentage of cases being signed out in over 3 days. Diagnosis of malignancy (including staging of the neoplasia), consultation with other pathologists, having had a frozen section, and use of immunohistochemical stains were significantly associated with increased turnaround time in univariate analysis. Decalcification was not associated with increased turnaround time. In multivariate analysis, consultation with other pathologists, use of immunohistochemistry, diagnosis of malignancy, and the number of slides studied continued to be significantly associated with prolonged turnaround time. Our findings suggest that diagnosis of malignancy is central to significantly prolonging the turnaround time for surgical pathology specimens, thus institutions that serve cancer centers will have longer turnaround time than those that do not.

Orthopaedic surgical-site infections prolong hospital stays, double rehospitalization rates, and increase healthcare costs. Additionally, patients with orthopaedic surgical-site infections (SSI) have substantially greater physical limitations and reductions in their health-related quality of life. However, the risk factors for SSI after operative fracture care are unclear. We determined the incidence and quantified modifiable and nonmodifiable risk factors for SSIs in patients with orthopaedic trauma undergoing surgery. We retrospectively indentified, from our prospective trauma database and billing records, 1611 patients who underwent 1783 trauma-related procedures between 2006 and 2008. Medical records were reviewed and demographics, surgery-specific data, and whether the patients had an SSI were recorded. We determined which if any variables predicted SSI. Six factors independently predicted SSI: (1) the use of a drain, OR 2.3, 95% CI (1.3-3.8); (2) number of operations OR 3.4, 95% CI (2.0-6.0); (3) diabetes, OR 2.1, 95% CI (1.2-3.8); (4) congestive heart failure (CHF), OR 2.8, 95% CI (1.3-6.5); (5) site of injury tibial shaft/plateau, OR 2.3, 95% CI (1.3-4.2); and (6) site of injury, elbow, OR 2.2, 95% CI (1.1-4.7). The risk factors for SSIs after skeletal trauma are most strongly determined by nonmodifiable factors: patient infirmity (diabetes and heart failure) and injury complexity (site of injury, number of operations, use of a drain). Level II, prognostic study. See the Guideline for Authors for a complete description of levels of evidence.

To evaluate whether surgical complications after kidney transplantation correlate with surgeon's experience and whether individual surgeons' complication rates improve during their learning process. Retrospective analysis: A generalized linear mixed-effects model was used to identify risk factors for surgical complications. Plots of cumulative sums of complications were used to evaluate the individual surgeons' performance. Single-center experience of a teaching hospital in Switzerland. Consecutive kidney transplant recipients operated from 1962 until 2003. A total of 1496 kidney transplants were analyzed; 73% were from deceased donors and 27% from living donors. At least 1 surgical complication occurred in 352 patients (24%). Male gender (odds ratio [OR] = 1.35, 95% CI: 1.04-1.74), donor's age (OR = 1.14, 95% CI: 1.06-1.24 per decade increment), and third or fourth vs. first or second transplant in a recipient (OR = 2.90, 95% CI: 1.02-8.24) were significantly associated with surgical complications. The surgeon's transplant experience was not found to be associated with surgical complications. Even surgeons with an experience of less than 10 kidney transplants did not have higher complication rates, 30-day mortality, or 1-year graft survival. Individual surgeons' complication rates analyzed by cumulative sum plots did not improve with increasing experience. We present the largest single-center study on surgical complications after kidney transplantation, with unique data on the surgeon's experience for every single procedure. We found no evidence for a learning curve during training for kidney transplantation. We conclude that carefully selected experienced general and vascular surgeons can achieve good results in kidney transplantation after a relatively short training period.

Epilepsy is a frequent complication of central nervous system (CNS) infections. Post-infectious epilepsy is commonly refractory to medical treatment and plays a pivotal role for the poor long-term outcome of CNS infections. To provide an overview of clinical characteristics and risk factors of seizures associated with CNS infections. In addition, to summarize the state of the art of anticonvulsive treatment and the pre-surgical evaluation process in refractory cases. A comprehensive literature search for articles published between January 1970 and December 2011 was carried out. The occurrence of seizures during the acute course of meningitis, encephalitis and brain abscess is the main risk factor for the development of post-infectious epilepsy. There is a shortage of trials evaluating the efficacy of prophylactic and symptomatic treatment during the course of acute infection. Moreover, there are no randomized-controlled trials studying anticonvulsive drugs and their combinations for the management of post-infectious epilepsy. In a selected group of patients, however, medically refractory focal epilepsy is potentially curable by surgery. Further studies are required to improve the pathogenetic understanding of post-infectious epilepsy in order to develop preventive measures as well as to evaluate additional medical and surgical treatment strategies for the patients currently not considered for surgery. © 2012 The Author(s) European Journal of Neurology © 2012 EFNS.

Gastrointestinal stromal tumors (GISTs) and non-GIST subepithelial tumors (SETs) account for about 75 and 25% of gastric hypoechoic SETs ≥2 cm, respectively. Therefore, identifying preoperative predictive factors for GISTs are required to refine surgical indications. We performed a retrospective review of 375 surgically resected gastric hypoechoic SETs ≥2 cm. Demographic data and tumor characteristics based on upper endoscopy and CT findings were compared between GIST and non-GIST SETs originating from muscularis propria layer (leiomyomas, Schwannomas, glomus tumors, and ectopic pancreas). In cardia, leiomyomas were found twice more frequently than GISTs (63.6 versus 31.8%). Perilesional lymph node enlargement (PLNE) was found only in patients with GIST or Schwannomas. Patients with GIST showed a significantly lower rate of PLNE than those with Schwannomas (3.5 versus 29.0%). In multivariate analysis, tumor site outside cardia (odds ratio, 9.157), absence of PLNE (odds ratio, 11.519), old age, large tumor size, exophytic growth pattern, and ulceration or dimpling were identified as independent preoperative predictive factors for GISTs versus non-GIST SETs. The effort for preoperative pathologic diagnosis such as endosonography-guided tissue sampling might be positively considered for SETs at cardia and SETs with PLNE where the possibility of GIST is low.

Chronic subdural hematoma (CSDH) is a rare complication of unruptured aneurysm clipping surgery. The purpose of this study was to identify the incidence and risk factors of postoperative CSDH after surgical clipping for unruptured anterior circulation aneurysms. This retrospective study included 518 patients from a single tertiary institute from January 2008 to December 2013. CSDH was defined as subdural hemorrhage which needed surgical treatment. The degree of brain atrophy was estimated using the bicaudate ratio (BCR) index. We used uni- and multivariate analyses to identify risk factors correlated with CSDH. Sixteen (3.1%) patients experienced postoperative CSDH that required burr hole drainage surgery. In univariate analyses, male gender (p<0.001), size of aneurysm (p=0.030), higher BCR index (p=0.004), and the use of antithrombotic medication (p=0.006) were associated with postoperative CSDH. In multivariate analyses using logistic regression test, male gender [odds ratio (OR) 4.037, range 1.287-12.688], high BCR index (OR 5.376, range 1.170-25.000), and the use of antithrombotic medication (OR 4.854, range 1.658-14.085) were associated with postoperative CSDH (p<0.05). Postoperative subdural fluid collection and arachnoid plasty were not showed statistically significant difference in this study. The incidence of CSDH was 3.1% in unruptured anterior circulation aneurysm surgery. This study shows that male gender, degree of brain atrophy, and the use of antithrombotic medication were associated with postoperative CSDH.

To identify the rate of surgical site infection (SSI) after Cesarean delivery (CD) and determine risk factors predictive for infection at a large academic institution. This was a retrospective cohort study in women undergoing CD during 2013. SSIs were defined by Centers for Disease Control (CDC) criteria. Chi square and t-tests were used for bivariate analysis and multivariate logistic regression was used to identify SSI risk factors. In 2419 patients, the rate of SSI was 5.5% (n = 133) with cellulitis in 4.9% (n = 118), deep incisional infection in 0.6% (n = 15) and intra-abdominal infection in 0.3% (n = 7). On multivariate analysis, SSI was higher among CD for labor arrest (OR 2.4; 95%CI 1.6-3.5; p infection control interventions.

A number of risk factors have significant influence on CVD incidence. Early identification of risk factors related to our lifestyle facilitates taking proper actions aiming at the reduction of their negative impact on health.Aim: The aim of the study was to compare the prevalence of CVD risk factors between patients aged over 65 years and patients of other age groups in surgical wards.Material and methods: The study was conducted for assessment and finding the distribution of major risk factors of CVD among 420 patients aged 18–84 years who were hospitalized in surgical wards. Interview, anthropometric measurements, blood pressure, and fasting blood tests for biochemical analysis were conducted in all subjects. Statistical analysis of the material was performed using Student’s t-test, chi-square test, Fisher’s exact test, Mann–Whitney U-test, and analysis of variance.Results: While abdominal obesity (83.3%, overweight and obesity (68%, hypertension (65.1%, hypercholesterolemia (33.3%, and low level of physical activity (29.1% were the most common CVD risk factors among patients over 65 years old, abdominal obesity (36.2%, overweight and obesity (36.1%, and current smoking were the most common CVD risk factors among patients up to the age of 35. In the age group over 65, the least prevalent risk factors for CVD were diabetes mellitus (14.8%, depressive episodes (13.6%, abuse of alcohol (11.4%, and smoking (7.8%. In the group under 35 years, we have not reported any cases of hypercholesterolemia and a lesser number of patients suffered from diabetes and HTN.Conclusion: Distribution of the major risk factors for CVD is quite high in the adult population, especially in the age group over 65

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: is there a difference in cardiothoracic surgery outcomes in terms of morbidity or mortality of patients operated on by a sleep-deprived surgeon compared with those operated by a non-sleep-deprived surgeon? Reported search criteria yielded 77 papers, of which 15 were deemed to represent the best evidence on the topic. Three studies directly related to cardiothoracic surgery and 12 studies related to non-cardiothoracic surgery. Recommendations are based on 18 121 cardiothoracic patients and 214 666 non-cardiothoracic surgical patients. Different definitions of sleep deprivation were used in the studies, either reviewing surgeon's sleeping hours or out-of-hours operating. Surgical outcomes reviewed included: mortality rate, neurological, renal, pulmonary, infectious complications, length of stay, length of intensive care stay, cardiopulmonary bypass times and aortic-cross-clamp times. There were no significant differences in mortality or intraoperative complications in the groups of patients operated on by sleep-deprived versus non-sleep-deprived surgeons in cardiothoracic studies. One study showed a significant increase in the rate of septicaemia in patients operated on by severely sleep-deprived surgeons (3.6%) compared with the moderately sleep-deprived (0.9%) and non-sleep-deprived groups (0.8%) (P = 0.03). In the non-cardiothoracic studies, 7 of the 12 studies demonstrated statistically significant higher reoperation rate in trauma cases (P sleep deprivation in cardiothoracic surgeons on morbidity or mortality. However, overall the non-cardiothoracic studies have demonstrated that operative time and sleep deprivation can have a significant impact on overall morbidity and mortality. It is likely that other confounding factors concomitantly affect outcomes in out-of-hours surgery. © The Author 2014. Published by Oxford University Press on behalf of

Recurrent instability remains of concern after arthroscopic Bankart reconstruction. We evaluated various technical factors including anchor design, anchor material, number of anchors used, and interval closure on risk of recurrent instability after arthroscopic Bankart reconstruction. A systematic review of MEDLINE and Cochrane databases was conducted, following PRISMA guidelines. Extracted data were recorded on a standardized form. Methodological index for non-randomized studies (MINORS) and Newcastle-Ottawa Scale (NOS) were used to assess study quality and risk bias. Because of study heterogeneity and low levels of evidence, meta-analysis was not possible. Pooled weighted means were calculated and individual study evaluation and comparisons (qualitative analysis) were performed for systematic review. Of 2097 studies identified, 26 met criteria for systematic review. Pooled weighted means revealed 11.4% versus 15% recurrent instability with 3 or more suture anchors versus fewer than 3 anchors, 10.1% versus 7.8% with absorbable versus nonabsorbable suture anchors, respectively, and 8.0% versus 9.4% with knotless versus standard anchors, respectively. Interval closure did not qualitatively decrease recurrent instability or decrease range of motion. Our systematic review reveals that despite individual study, and previous systematic reviews pointing to the contrary, the composite contemporary published literature would support no difference in the risk of recurrent instability after arthroscopic Bankart reconstruction with rotator interval closure, differing numbers of anchors used for the repair, use of knotless versus standard anchors, or use of bioabsorbable versus nonabsorbable anchors. We recommend surgeons focus on factors that have been shown to modify the risk factors after arthroscopic Bankart reconstruction, such as patient selection.

Non-technical skills are essential for safe and effective surgery. Several tools to assess surgeons' non-technical skills from the clinician's perspective have been developed. However, a reliable measurement tool using a patient-centred approach does not currently exist. The aim of this study was to translate the existing Non-Technical Skills for Surgeons (NOTSS) tool into a patient-centred evaluation tool. Data were gathered from four cohorts of patients using an iterative four-stage mixed-methods research design. Exploratory and confirmatory factor analyses were performed to establish the psychometric properties of the tool, focusing on validity, reliability, usability and parsimony. Some 534 patients were recruited to the study. A total of 24 patient-centred non-technical skill items were developed in stage 1, and reduced to nine items in stage 2 using exploratory factor analysis. In stage 3, confirmatory factor analysis demonstrated that these nine items each loaded on to one of three factors, with excellent internal consistency: decision-making, leadership, and communication and teamwork. In stage 4, validity testing established that the new tool was independent of physician empathy and predictive of surgical quality. Surgical leadership emerged as the most dominant skill that patients could recognize and evaluate. A novel nine-item assessment tool has been developed. The Patients' Evaluation of Non-Technical Skills (PENTS) tool allows valid and reliable measurement of surgeons' non-technical skills from the patient perspective. © 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.

In this study, we aimed to evaluate, the efficacy of surgical methods and the factors affecting the residual stone rate by scrutinizing retrospectively the patients who had undergone renal stone surgery. Records of 109 cases of kidney stones who had been surgically treated between January 2010, and July 2013 were reviewed. Patients were divided into three groups in terms of surgical treatment; open stone surgery, percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS). Patients' history, physical examination, biochemical and radiological images and operative and postoperative data were recorded. The patients had undergone PNL (n=74; 67.9%), RIRS (n=22;20.2%), and open renal surgery (n=13; 11.9%). The mean and median ages of the patients were 46±9, 41 (21-75) and, 42 (23-67) years, respectively. The mean stone burden was 2.6±0.7 cm(2) in the PNL, 1.4±0.1 cm(2) in the RIRS, and 3.1±0.9 cm(2) in the open surgery groups. The mean operative times were 126±24 min in the PNL group, 72±12 min in the RIRS group and 82±22 min in the open surgery group. The duration of hospitalisation was 3.1±0.2 days, 1.2±0.3 days and 3.4±1.1 days respectively. While the RIRS group did not need blood transfusion, in the PNL group blood transfusions were given in the PNL (n=18), and open surgery (n=2) groups. Residual stones were detected in the PNL (n=22), open surgery (n=2), and RIRS (n=5) groups. PNL and RIRS have been seen as safe and effective methods in our self application too. However, it should not be forgotten that as a basical method, open surgery may be needed in cases of necessity.

Advanced age is known to be a significant risk factor for the rupture of intracranial aneurysms. The impact of age on outcomes of surgically treated patients with unruptured intracranial aneurysms (UIAs) is less clear. A total of 663 consecutive patients with 823 surgically treated UIAs were evaluated. UIAs, which need bypass surgery including low-flow or high-flow bypass, were defined as complex aneurysms. Aneurysm size was categorized as small (<15 mm), large (15-24 mm), and giant (≥25 mm). In patients without symptoms, a poor outcome is defined as a modified Rankin Scale (mRS) score of 2-6. In those with mRS score higher than 1 as a result of UIA-related symptoms or other comorbidities, a poor outcome is defined as an increase of 1 or more on the mRS. Outcomes were evaluated at the 6-month and 12-month follow-up examinations. The mean age was 62 ± 12 years and 650 UIAs (78%) were observed in women. Previously treated aneurysm (P = 0.009), posterior circulation aneurysm (P < 0.0001), complex aneurysm (P < 0.0001), a larger size (P = 0.011), and perforator territory infarction (P < 0.0001) were related to poor outcome at 6 months, and posterior circulation aneurysm (P < 0.0001), complex aneurysm (P < 0.0001), a larger size (P = 0.035), and perforator territory infarction (P = 0.013) were related to poor outcome at 12 months. Age was not associated with poor outcome in patients with UIAs who undertook direct surgery. Although risks and benefits of aneurysm treatment in older patients should be carefully considered, surgical treatment of UIAs in the elderly should be considered positively.

To evaluate factors associated with positive online patient ratings and written comments regarding hand surgeons. We randomly selected 250 hand surgeons from the American Society for Surgery of the Hand member directory. Surgeon demographic and rating data were collected from 3 physician review Web sites (www.HealthGrades.com, www.Vitals.com, and www.RateMDs.com). Written comments were categorized as being related to professional competence, communication, cost, overall recommendation, staff, and office practice. Online presence was defined by 5 criteria: professional Web site, Facebook page, Twitter page, and personal profiles on www.Healthgrades.com and/or www.Vitals.com. A total of 245 hand surgeons (98%) had at least one rating among the 3 Web sites. Mean number of ratings for each surgeon was 13.4, 8.3, and 1.9, respectively, and mean overall ratings were 4.0 out of 5, 3.3 out of 4, and 3.8 out of 5 stars on www.HealthGrades.com, www.Vitals.com, and www.RateMDs.com, respectively. Positive overall ratings were associated with a higher number of ratings, Castle Connolly status, and increased online presence. No consistent correlations were observed among online ratings and surgeon age, sex, years in practice, practice type (ie, private practice vs academics), and/or geographic region. Finally, positive written comments were more often related to factors dependent on perceived surgeon competence, whereas negative comments were related to factors independent of perceived competence. Physician review Web sites featured prominently on Google, and 98% of hand surgeons were rated online. This study characterized hand surgeon online patient ratings as well as identified factors associated with positive ratings and comments. In addition, these findings highlight how patients assess care quality. Understanding hand surgeon online ratings and identifying factors associated with positive ratings are important for both patients and surgeons because of the recent growth in

Handedness is perhaps the most studied human asymmetry. Laterality is the preference shown for one side and it has been studied in many aspects of medicine. Studies have shown that some orthopaedic procedures had poorer outcomes and identified laterality as a contributing factor. We developed a questionnaire to assess laterality in orthopaedic surgery and compared this to an established scoring system. Sixty-two orthopaedic surgeons surveyed with the validated Waterloo Handedness Questionnaire (WHQ) were compared with the self developed Orthopaedic Handedness Questionnaire (OHQ). Fifty-eight were found to be right hand dominant (RHD) and 4 left hand dominant (LHD). In RHD surgeons, the average WHQ score was 44.9% and OHQ 15%. For LHD surgeons the WHQ score was 30.2% and OHQ 9.4%. This represents a significant amount of time using the non dominant hand but does not necessarily determine satisfactory or successful dexterity transferable to the operating room. Training may be required for the non dominant side.

A career as a plastic surgeon is both rewarding and challenging. The road to becoming a surgeon is a long arduous endeavor and can bring significant challenges not only to the surgeon but their family. A study by the American College of Surgeons (ACS) suggested that over 40% of surgeons experience burnout and a recent survey of American Society of Plastic Surgeons (ASPS) showed that more than one-fourth of plastic surgeons have signs of professional burnout. Burnout is a state of physical and mental exhaustion. The three main components of burnout are emotional exhaustion, depersonalization, and reduced personal accomplishment. Exhaustion occurs as a result of emotional demands. Depersonalization refers to a cynical, negative or a detached response to patient care. The reduced accomplishment refers to a belief that one can no longer work effectively. There has been a recent explosion in the literature characterizing burnout within the surgical profession. Reports of burnout, burnout victims, and burnout syndrome are filling the medical literature, books, blogs, and social media across all different specialties. Burnout in a plastic surgeon has negative and potentially fatal repercussions to the surgeon, their family, their patients, their staff, colleagues, coworkers, and their organization. To date, there are a limited number of publications addressing burnout in the plastic surgery community. The goals of this paper are to review the symptoms of burnout, its effect on plastic surgeons, and discuss potential solutions for burnout prevention and physician wellness.

Retention of academic Mohs surgeons is important for the growth of this specialty and teaching of residents and students. To examine factors that influence retention of Mohs surgeons in academics and to better understand reasons for their departure. A survey was electronically distributed to academic Mohs surgeons in the American College of Mohs Surgery, asking them to rate the importance of several variables on their decision to remain in academia. Private practice Mohs surgeons who had left academics were also surveyed. Two hundred thirty-six dermatologic surgeons completed the survey. Twenty-nine percent work full time in academics, and approximately 7% work part time. The top reasons for practicing in the academic setting are intellectual stimulation, teaching opportunities, and collaboration with other university physicians and researchers. Seventy-one percent of respondents reported they would stay in academics, 7% indicated they would not, and 22% were unsure. Unfair compensation, inadequate support staff, poor leadership, increased bureaucracy, and decreased autonomy were top reasons that may compel a Mohs surgeon to leave. Opportunities for intellectual stimulation, collaboration, and teaching remain the main draw for academic Mohs surgeons. A supportive environment, strong leadership, and establishing fair compensation are imperative in ensuring their stay.

Aspiration pneumonia in hospitalized surgical patients has been associated with a mortality of approximately 30%. The aim of this study was to assess pre-, intra- and postoperative risk factors for mortality in patients suffering aspiration pneumonia after abdominal surgery. Retrospective study from 01/2006-12/2012 of patients with clinically and radiologically confirmed aspiration pneumonia after abdominal surgery. A total of 70 patients undergoing abdominal surgery and postoperative aspiration pneumonia were identified. There were 53 (76%) male patients, the mean age was 71 ± 12 years and the mean ASA score was 3 ± 1. The surgical procedures included 32 colorectal or small bowel resections, 10 partial liver resections, 9 gastric surgeries, 8 esophageal resections, 5 pancreatic surgeries, and 6 hernia repairs. Aspiration pneumonia occurred at mean postoperative day 7 ± 10. Overall, 53% (n = 37) of patients required re-intubation, with 4 ± 5 days of additional mechanical ventilation. Mean hospital and ICU length of stay was 32 ± 25 days and 6 ± 9 days, respectively. Overall mortality was 27% (n = 19). Forward logistic regression revealed older age [OR 7.41 (95% CI: 1.29-42.62)], bilateral aspiration pneumonia [OR 7.39 (95% CI: 1.86-29.29)] and intraoperative requirement of blood component transfusion [OR 5.09 (95% CI: 1.34-19.38)] as independent risk factors for mortality (overall R(2) = 0.336). Postoperative aspiration pneumonia remains a severe complication with significant mortality. Increasing age, the need for intraoperative blood component transfusion and bilateral pulmonary infiltrates are independent risk factors for fatal outcome after aspiration pneumonia. Therefore, these patients suffering aspiration pneumonia require special attention and increased monitoring. Copyright © 2016 IJS Publishing Group Limited. Published by Elsevier Ltd.

Full Text Available Krukenberg tumor originated from stomach in female patients is common in clinical practice, but it is still uncertain whether surgical resection of ovarian metastases could improve the outcome. Some studies suggested that a certain group of patients could benefit from the resection of ovarian metastases. However, conclusions were different between studies and there was no data to illustrate if certain molecular markers were associated with patients' survival. In this study, we analyzed the effects of resection of ovarian metastases, and investigated prognostic factors in 133 patients with ovarian metastases originated from stomach. Furthermore, we examined the expression of some cancer stem cells (CSCs markers or related molecules in 64 ovarian metastases specimens and analyzed the correlation between these molecules and patients' survival. We found that the median overall survival (mOS of all 133 patients was 16 months, and "gastrectomy" and "without ascites" were two independent prognostic factors associated with longer survival. The mOS of the patients with gastrectomy was longer than that of patients had not undergone gastrectomy (19 vs. 9 months, p = 0.048. Patients without ascites survived longer than those with ascites (mOS: 21 vs. 13 months, p = 0.008. We also found that Sox2, CD44 or CD133 positive expression in ovarian metastases were risk factors correlated with poor survival, and Sox2 expression was an independent prognostic indicator. These results suggested that ovarian metastasectomy might help to prolong the survivor of some patients with Krukenberg tumor originated from stomach. Patients without ascites, and with resected or resectable primary gastric cancer lesion could get benefit from and be potential candidate for surgical treatment. The expression of Sox2 might serve as a prognostic indicator for predicting patients' survival and be helpful for selecting patients in future.

In Japan, gender inequality between males and females in the medical profession still exists. We examined gender gaps in surgeons' incomes. Among 8,316 surgeons who participated in a 2012 survey by the Japan Surgical Society, 546 women and 1,092 men within the same postgraduation year were selected randomly with a female-to-male sampling ratio of 1:2 (mean age, 36 years; mean time since graduation, 10.6 years). Average annual income was 9.2 million JPY for women and 11.3 million JPY for men (P income of men remained 1.5 million JPY greater after adjusting for gender, age, marital status, number of children, number of beds, current position, and working hours (Model 1). In Model 2, in which 2 statistical interaction terms between annual income and gender with marital status and number of children were added together with variables in Model 1, both interactions became significant, and the gender effect became nonsignificant. For men, average annual income increased by 1.1 million JPY (P income decreased by 0.73 million JPY per child (P = .0005). Male surgeons earn more than female surgeons, even after adjusting for other factors that influenced a surgeon's salary. In addition, married men earn more than unmarried men, but no such trend is observed for women. Furthermore, as the number of children increases, annual income increases for men but decreases for women. Copyright © 2016 Elsevier Inc. All rights reserved.

Surgical site infections (SSIs) after colectomy for colon cancer (CC), Crohn's disease (CD), and diverticulitis (DD) significantly impact both the immediate postoperative course and long-term disease-specific outcomes. We aim to profile the effect of diagnosis on SSI after segmental colectomy using the National Surgical Quality Improvement Program (NSQIP) data set. NSQIP data from 2006 to 2011 were investigated, and segmental colectomy procedures performed for the diagnoses of Crohn's disease, DD, and colon malignancy were included. SSI complications were compared by diagnosis using univariate and multivariate analysis. We included 35,557 colectomy cases in the analysis. CD had the highest rate of postoperative SSI (17 vs. 13% DD vs. 10% CC; p risk for acquiring at least one SSI (odds ratio (OR) = 1.38, p ≤ 0.001), deep incisional SSI (OR = 1.85, p = 0.03), and organ space SSI (OR = 1.51, p = 0.02). For patients undergoing segmental colectomy in the NSQIP data set, statistically significant increases in SSI are seen in CD, but not DD, when compared to CC, thus confirming CD as an independent risk factor for SSI.

We aimed to characterize the landscape of surgeon participation in early accountable care organizations (ACOs) and to identify specialty-, organization-, and market-specific factors associated with ACO participation. Despite rapid deployment of alternative payment models (APMs), little is known about the prevalence of surgeon participation, and key drivers behind surgeon participation in APMs. Using data from SK&A, a research firm, we evaluated the near universe of US practices to characterize ACO participation among 125,425 US surgeons in 2015. We fit multivariable logistic regression models to characterize key drivers of ACO participation, and more specifically, the interaction between ACO affiliation and organizational structure. Of 125,425 US surgeons, 27,956 (22.3%) participated in at least 1 ACO program in 2015. We observed heterogeneity in participation by subspecialty, with trauma and transplant reporting the highest rate of ACO enrollment (36% for both) and plastic surgeons reporting the lowest (12.9%) followed by ophthalmology (16.0%) and hand (18.6%). Surgeons in group practices and integrated systems were more likely to participate relative to those practicing independently (aOR 1.57, 95% CI 1.50, 1.64; aOR 4.87, 95% CI 4.68, 5.07, respectively). We observed a statistically significant interaction (P organization. Model-derived predicted probabilities revealed that, within each specialty, surgeons in integrated health systems had the highest predicted probabilities of ACO and those practicing independently generally had the lowest. We observed considerable variation in ACO enrollment among US surgeons, mediated at least in part by differences in practice organization. These data underscore the need for development of frameworks to characterize the strategic advantages and disadvantages associated with APM participation.

The objectives of patient selection and counseling are ultimately to enhance successful outcomes. However, the definition for success is often narrowly defined in published literature (ability to complete surgery, complications, satisfaction) and fails to account for patient desires and expectations, temporal changes, natural history of underlying diseases, or independent validation. Factors associated with satisfaction and dissatisfaction are often surgery-specific, although correlation with pre-operative expectations, revisions, and complications are common with most procedures. The process of appropriate patient selection is determined by the integration of patient and surgeon factors, including psychological capacity to handle unsatisfactory results, baseline expectations, complexity of case, and surgeon volume and experience. Using this model, a high-risk scenario includes one in which a low-volume surgeon performs a complex case in a patient with limited psychological capacity and high expectations. In contrast, a high-volume surgeon performing a routine case in a male with low expectations and abundant psychiatric reserve is more likely to achieve a successful outcome. To further help identify patients who are at high risk for dissatisfaction, a previously published mnemonic is recommended: CURSED Patient (compulsive/obsessive, unrealistic, revision, surgeon shopping, entitled, denial, and psychiatric). Appropriate patient counseling includes setting appropriate expectations, reviewing the potential and anticipated risks of surgery, post-operative instruction to limit complications, and long-term follow-up. As thorough counseling is often a time-consuming endeavor, busy practices may elect to utilize various resources including educational materials, advanced practice providers, or group visits, among others. The consequences for poor patient selection and counseling may range from poor surgical outcomes and patient dissatisfaction to lawsuits, loss of

We surveyed 331 patients undergoing total hip or knee arthroplasty pre-operatively, and patients and surgeons were both surveyed 6 and 12 months post-operatively. We identified variables (demographic factors, operative factors and patient expectations) as possible predictors for discordance in patient-surgeon satisfaction. At 12 months, 94.5% of surgeons and 90.3% of patients recorded satisfaction with the outcome. The discordance between patient and surgeon satisfaction was mainly due to patient dissatisfaction-surgeon satisfaction. In an adjusted analysis, the strongest predictors of discordance in patient-surgeon satisfaction were unmet patient expectations and the presence of complications. Advice to potential joint arthroplasty candidates regarding the decision to proceed with surgery should be informed by patient reported outcomes, rather than the surgeon's opinion of the likelihood of success.

We investigated the associations of surgeons' emotional intelligence and surgeons' empathy with patient-surgeon relationships, patient perceptions of their health, and patient satisfaction before and after surgical procedures. We used multi-source approaches to survey 50 surgeons and their 549 outpatients during initial and follow-up visits. Surgeons' emotional intelligence had a positive effect (r = .45; p self-reported health status (r = .21; p emotional intelligence than by empathy. Furthermore, empathy indirectly affects patient satisfaction through its positive effect on health outcomes, which have a direct effect on patients' satisfaction with their surgeons.
Full Text Available Background: Degenerative lumbar scoliosis surgery can lead to development of adjacent segment degeneration (ASD after lumbar or thoracolumbar fusion. Its incidence, risk factors, morbidity and correlation between radiological and clinical symptoms of ASD have no consensus. We evaluated the correlation between the occurrence of radiologic adjacent segment disease and certain imperative parameters. Materials and Methods: 98 patients who had undergone surgical correction and lumbar/thoracolumbar fusion with pedicle screw instrumentation for degenerative lumbar scoliosis with a minimum 5 year followup were included in the study. We evaluated the correlation between the occurrence of radiologic adjacent segment disease and imperative patient parameters like age at operation, sex, body mass index (BMI, medical comorbidities and bone mineral density (BMD. The radiological parameters taken into consideration were Cobb′s angle, angle type, lumbar lordosis, pelvic incidence, intercristal line, preoperative existence of an ASD on plain radiograph and magnetic resonance imaging (MRI and surgical parameters were number of the fusion level, decompression level, floating OP (interlumbar fusion excluding L5-S1 level and posterolateral lumbar interbody fusion (PLIF. Clinical outcomes were assessed with the Visual Analogue Score (VAS and Oswestry Disability Index (ODI. Results: ASD was present in 44 (44.9% patients at an average period of 48.0 months (range 6-98 months. Factors related to occurrence of ASD were preoperative existence of disc degeneration (as revealed by MRI and age at operation ( P = 0.0001, 0.0364. There were no statistically significant differences between radiological adjacent segment degeneration and clinical results (VAS, P = 0.446; ODI, P = 0.531. Conclusions: Patients over the age of 65 years and with preoperative disc degeneration (as revealed by plain radiograph and MRI were at a higher risk of developing ASD.

Independent risk factors for surgical site infection (SSI) after cesarean section have not been well documented, despite the large number of cesarean sections performed and the relatively common occurrence of SSI. To determine independent risk factors for SSI after low transverse cesarean section. Retrospective case-control study. Barnes-Jewish Hospital, a 1,250-bed tertiary care hospital. A total of 1,605 women who underwent low transverse cesarean section during the period from July 1999 to June 2001. Using the International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes for SSI or wound complication and/or data on antibiotic use during the surgical hospitalization or at readmission to the hospital or emergency department, we identified potential cases of SSI in a cohort of patients who underwent a low transverse cesarean section. Cases of SSI were verified by chart review using the definitions from the Centers for Disease Control and Prevention's National Nosocomial Infections Surveillance System. Control patients without SSI or endomyometritis were randomly selected from the population of patients who underwent cesarean section. Independent risk factors for SSI were determined by logistic regression. SSIs were identified in 81 (5.0%) of 1,605 women who underwent low transverse cesarean section. Independent risk factors for SSI included development of subcutaneous hematoma after the procedure (adjusted odds ratio [aOR], 11.6 [95% confidence interval [CI], 4.1-33.2]), operation performed by the university teaching service (aOR, 2.7 [95% CI, 1.4-5.2]), and a higher body mass index at admission (aOR, 1.1 [95% CI, 1.0-1.1]). Cephalosporin therapy before or after the operation was associated with a significantly lower risk of SSI (aOR, 0.2 [95% CI, 0.1-0.5]). Use of staples for skin closure was associated with a marginally increased risk of SSI. These independent risk factors should be incorporated into approaches for the prevention
Full Text Available Introduction. Surgical tooth extraction is a common procedure in dentistry. However, numerous extraction cases show a high level of difficulty in practice. This difficulty is usually related to inadequate visualization, improper instrumentation, or other factors related to the targeted tooth (e.g., ankyloses or presence of bony undercut. Methods. In this work, the author presents a new technique for surgical tooth extraction based on 3D imaging, computer planning, and a new concept of computer-assisted manufacturing. Results. The outcome of this work is a surgical guide made by 3D printing of plastics and CNC of metals (hybrid outcome. In addition, the conventional surgical cutting tools (surgical burs are modified with a number of stoppers adjusted to avoid any excessive drilling that could harm bone or other vital structures. Conclusion. The present outcome could provide a minimally invasive technique to overcome the routine complications facing dental surgeons in surgical extraction procedures.

Purpose Colonic diverticulitis is uncommon in Korea, but the incidence is rapidly increasing nowadays. The clinical features and the factors associated with complications of diverticulitis are important for properly treating the disease. Methods A retrospective review of the medical records of 225 patients that were prospectively collected between October 2007 and September 2016 was conducted. Results Diverticulitis was detected mainly in men and women aged 30 to 50 years. Diverticulitis more frequently affected the right colon (n = 194, 86.2%), but age was higher in case of left colonic involvement (42 years vs. 57 years, P diverticulitis. In the multivariate analysis, a risk factor for complicated diverticulitis was left colonic involvement (P diverticulitis, age over 50 was the only significant risk factor for surgical treatment (P = 0.024; RR, 19.350; 95% CI, 1.474–254.023). Conclusion In patients over 50 years of age with left colonic diverticulitis, a preventive colectomy should be reconsidered as one of the options for treatment. PMID:29159165

Blood transfusion is linked to a negative outcome for malignant tumors. The aim of this study was to evaluate aggressive surgical resection for hilar cholangiocarcinoma (HCCA) and assess the impact of perioperative blood transfusion on long-term survival. Sixty-six consecutive major hepatectomies with en bloc resection of the caudate lobe and extrahepatic bile duct for HCCA were performed using macroscopically curative resection at our institute from 2002 to 2012. Clinicopathologic factors for recurrence and survival were retrospectively assessed. Overall survival rates at 1, 3, and 5 years were 86.7, 47.3, and 35.7 %, respectively. In univariate analysis, perioperative blood transfusion and a histological positive margin were two of several variables found to be significant prognostic factors for recurrence or survival (Pblood transfusion was independently associated with recurrence (hazard ratio (HR)=2.839 (95 % confidence interval (CI), 1.370-5.884), P=0.005), while perioperative blood transfusion (HR=3.383 (95 % CI, 1.499-7.637), P=0.003) and R1 resection (HR=3.125 (95 % CI, 1.025-9.530), P=0.045) were independent risk factors for poor survival. Perioperative blood transfusion is a strong predictor of poor survival after radical hepatectomy for HCCA. We suggest that circumvention of perioperative blood transfusion can play an important role in long-term survival for patients with HCCA.

Cesarean surgical site infections (SSIs) are a major challenge in Thai-Myanmar border hospital settings. This study aimed to examine risk factors for SSIs after cesarean section. This was a prospective cohort study conducted in a Thai-Myanmar border hospital between January 2007 and December 2012. Data were collected from the medical record database by trained infection control nurses. Stepwise multivariable logistic regression was used for risk factor analysis and expressed as a risk ratio (RR). The cesarean SSI rate was 5.9% (293 SSIs in 4,988 cases). Of these, 17.1% were incisional SSIs (10.9% superficial and 6.2% deep incisional SSIs), and 82.9% were organ or space SSIs. Risk factors for cesarean organ-space SSIs included a wound class ≥3 (RR, 4.82; 95% confidence interval [CI], 3.41-6.83), ethnic minority (RR, 2.51; 95% CI, 1.61-3.92), hemoglobin Infection Control and Epidemiology, Inc.

This study aims to identify risk factors for cesarean delivery (CD) surgical site infection (SSI). study design: Retrospective analysis of 2,739 CDs performed at the University of Pittsburgh in 2011. CD SSIs were defined using National Healthcare Safety Network (NHSN) criteria. Chi-square test and t-test were used for bivariate analyses and multivariate logistic regression was used to identify SSI risk factors. Of 2,739 CDs, 178 (6.5%) were complicated by SSI. Patients with a SSI were more likely to have Medicaid, have resident physicians perform the CD, an American Society of Anesthesiologists (ASA) class of ≥ 3, chorioamnionitis, tobacco use, and labor before CD. In multivariable analysis, labor (odds ratio [OR], 2.35; 95% confidence interval [95% CI], 1.65-3.38), chorioamnionitis (OR, 2.24; 95% CI, 1.25-3.83), resident teaching service (OR, 2.15; 95% CI, 1.54-3.00), tobacco use (OR, 1.70; 95% CI, 1.04-2.70), ASA class ≥ 3 (OR, 1.61; 95% CI, 1.06-2.39), and CDs performed for nonreassuring fetal status (OR, 0.43; 95% CI, 0.26-0.67) were significantly associated with CD SSI. Multiple patient, provider, and procedure-specific risk factors contribute to CD SSI risk which may be targeted in infection-control efforts.

Recently there has been a great deal of new population based evidence on visual impairment generated in sub-Saharan Africa (SSA), thanks to the Rapid Assessment of Avoidable Blindness (RAAB) survey methodology. The survey provides information on the magnitude and causes of visual impairment for planning services and measuring their impact on eye health in administrative "districts" of 0.5-5 million people. The survey results describing the quantity and quality of cataract surgeries vary widely between study sites, often with no obvious explanation. The purpose of this study was to examine health system characteristics that may be associated with cataract surgical coverage and outcomes in SSA in order to better understand the determinants of reducing the burden of avoidable blindness due to cataract. This was a descriptive study using secondary and primary data. The outcome variables were collected from existing surveys. Data on potential district level predictor variables were collected through a semi-structured tool using routine data and key informants where appropriate. Once collected the data were coded and analysed using statistical methods including t-tests, ANOVA and the Kruskal-Wallis analysis of variance test. Higher cataract surgical coverage was positively associated with having at least one fixed surgical facility in the area; availability of a dedicated operating theatre; the number of surgeons per million population; and having an eye department manager in the facility. Variables that were associated with better outcomes included having biometry and having an eye department manager in the facility. There are a number of health system factors at the district level that seem to be associated with both cataract surgical coverage and post-operative visual acuity outcomes. This study highlights the needs for better indicators and tools by which to measure and monitor the performance of eye health systems at the district level. It is unlikely that

Shared decision making requires informing patients and ensuring that treatment decisions reflect their goals. It is not clear to what extent this happens for patients considering total joint replacement (TJR) for hip or knee osteoarthritis. We conducted a cross-sectional mail survey of osteoarthritis patients at 4 sites, who made a decision about TJR. The survey measured knowledge and goals, the decision making process, decision confidence, and decision regret. Decision quality was defined as the percentage of patients who had high knowledge scores and received treatments that matched their goals. Multivariable regression models examined factors associated with knowledge and decision quality. There were 382 patients who participated (78.6% response rate). Mean knowledge score was 61% (SD 20.7%). In multivariate linear regression, higher education, having TJR, and site were associated with higher knowledge. Many patients (73%) received treatments that matched their goals. Thirty-one percent of patients met our definition for high decision quality. Higher decision making process scores, higher quality of life scores, and site were associated with higher decision quality. Patients who had high decision quality had less regret (73.1% vs 58.5%, p = 0.007) and greater confidence (9.0 [SD 1.6] vs 8.2 [SD 2.3] out of 10, p osteoarthritis treatment met both criteria for a high quality decision.

Full Text Available Both anaesthetics and surgical trauma could strongly affect the production of tumour necrosis factor α (TNFα. During in vitro experiments the authors found that anaesthetics modulate the production of TNFα by peripheral blood mononuclear cells. Notably, Pentothal strongly increased the production of the cytokine as compared to both lipopolysacchride treated and control mononuclear cells, whereas in supernatants from Leptofen driven mononuclear cells TNFα was strongly reduced. On the other hand, Pavulon did not significantly affect the cytokine production. In the in vivo study, in an attempt to ameliorate the metabolic response to surgical trauma, L-carnitine was administered to 20 surgical patients, then the circulating TNFα was measured. The results indicate that the levels of circulating TNFα were strongly increased following surgery and that L-carnitine administration resulted in a strong reduction of TNFα. Thus, the data suggest that L-carnitine could be helpful in protecting surgical patients against dysmetabolism dependent on dysregulated production of TNFα.

To evaluate the efficacy of the virtual reality training simulator Eyesi to prepare surgeons for performing pars plana vitrectomies and its potential to predict the surgeons' performance. In a preparation phase, four participating vitreoretinal surgeons performed repeated simulator training with predefined tasks. If a surgeon was assigned to perform a vitrectomy for the management of complex retinal detachment after a surgical break of at least 60 hours it was randomly decided whether a warmup training on the simulator was required (n = 9) or not (n = 12). Performance at the simulator was measured using the built-in scoring metrics. The surgical performance was determined by two blinded observers who analyzed the video-recorded interventions. One of them repeated the analysis to check for intra-observer consistency. The surgical performance of the interventions with and without simulator training was compared. In addition, for the surgeries with simulator training, the simulator performance was compared to the performance in the operating room. Comparing each surgeon's performance with and without warmup trainingshowed a significant effect of warmup training onto the final outcome in the operating room. For the surgeries that were preceeded by the warmup procedure, the performance at the simulator was compared with the operating room performance. We found that there is a significant relation. The governing factor of low scores in the simulator were iatrogenic retinal holes, bleedings and lens damage. Surgeons who caused minor damage in the simulation also performed well in the operating room. Despite the large variation of conditions, the effect of a warmup training as well as a relation between the performance at the simulator and in the operating room was found with statistical significance. Simulator training is able to serve as a warmup to increase the average performance.

Full Text Available Abstract Background Veno-arterial extracorporeal membrane oxygenation (ECMO is a common modality of circulatory assist device used in children. We assessed the outcome of children who had ECMO following repair of congenital cardiac defects (CCD and identified the risk factors associated with hospital mortality. Methods From April 1990 to December 2003, 53 patients required ECMO following surgical correction of CCD. Retrospectively collected data was analyzed with univariate and multivariate logistic regression analysis. Results Median age and weight of the patients were 150 days and 5.4 kgs respectively. The indications for ECMO were low cardiac output in 16, failure to wean cardiopulmonary bypass in 13, cardiac arrest in 10 and cardio-respiratory failure in 14 patients. The mean duration of ECMO was 143 hours. Weaning off from ECMO was successful in 66% and of these 83% were survival to hospital-discharge. 37.7% of patients were alive for the mean follow-up period of 75 months. On univariate analysis, arrhythmias, ECMO duration >168 hours, bleeding complications, renal replacement therapy on ECMO, arrhythmias and cardiac arrest after ECMO were associated with hospital mortality. On multivariate analysis, abnormal neurology, bleeding complications and arrhythmias after ECMO were associated with hospital mortality. Extra and intra-thoracic cannulations were used in 79% and 21% of patients respectively and extra-thoracic cannulation had significantly less bleeding complications (p = 0.031. Conclusion ECMO provides an effective circulatory support following surgical repair of CCD in children. Extra-thoracic cannulation is associated with less bleeding complications. Abnormal neurology, bleeding complications on ECMO and arrhythmias after ECMO are poor prognostic indicators for hospital survival.

Category T4 nonsmall cell lung cancer (NSCLC) encompasses heterogenous subgroups. We retrospectively analyzed the survival of patients with surgically resected T4 NSCLC to evaluate the evidence for prognostic implications according to the subgroups of T4 category, nodal status, and resection completeness. Seventy-six patients with T4N0-2M0 NSCLC were divided into three subgroups within the T4 category: 24 patients with the tumor invading the mediastinal organs (mediastinal group), 16 with a malignant pleural effusion or dissemination (pleural group), and 36 with satellite tumor nodules within the ipsilateral primary tumor lobe (satellite group). Complete resection was possible in 47 patients (61.8%). The pathologic N statuses were N0 in 28, N1 in 13, and N2 in 35 patients. The overall survival of the 76 patients was 19.1% at 5 years. The overall 5-year survivals according to the three subgroups of the T4 category were as follows: mediastinal group, 18.2%; pleural group, 0%; and satellite group, 26.7% (mediastinal/satellite versus pleural, p = 0.037). Factors significantly influencing the overall 5-year survival were the pathologic N status (N2 versus N0-1, p = 0.022) and the completeness of resection (complete versus incomplete, p = 0.0001). A multivariate survival analysis demonstrated that the pathologic N status and the completeness of resection were significant independent predictors of a poorer prognosis even after adjusting for the subgroup of the T4 category. Resectable T4N0-1 NSCLC that is not due to pleural disease deserves consideration of aggressive surgical resection with expected 5-year survival of about 20%.
Mechanisms, Predisposing Factors, and Prognosis of Intraoperative Vertebral Subluxation During Pedicle Subtraction Osteotomy in Surgical Correction of Thoracolumbar Kyphosis Secondary to Ankylosing Spondylitis.

A retrospective study. To analyze the mechanisms, predisposing factors, and prognosis of the intraoperative vertebral subluxation (VS) during pedicle subtraction osteotomy (PSO) for thoracolumbar kyphosis secondary to ankylosing spondylitis (AS). VS is one of the most daunting challenges that surgeons encounter during PSO closure, especially in patients with AS with ankylosed and mostly osteoporotic spine. Unfortunately, there is a paucity of research designed to conceptualize the mechanisms, predisposing factors, and discuss the complication-avoidance strategies and prognosis. A retrospective single-center review was performed for a consecutive series of 153 patients with AS with rigid thoracolumbar kyphosis who underwent one-level PSO from April 2000 to December 2013. The incidence of the VS at the level of PSO during correction was analyzed and the potential causative factors were investigated. VS occurred in six patients with the incidence being 3.9% in this patient cohort. The predisposing factors were (1) early fracture of the anterior cortex of the osteotomized vertebra (OV); (2) excessive decancellation from vertebral body causing parallel collapse of the vertebral column with significant loss of the ability to create local lordosis; (3) improper manual osteoclasis due to insufficient decancellation of the OV; and (4) inappropriate application of cantilever technique and concomitant long instrumentation. The early surgical complication involved one patient with cerebrospinal fluid leakage at the osteotomized site, but no devastating neurological deficits. During follow-up, bone healing and adaptive vertebral remodeling with no rod breakage were observed for all these six patients. Intraoperative VS was a rare occurrence associated with inappropriate manual manipulation of osteotomy, gap closure, and rod insertion. Neurological complication was a potential risk, but could be well prevented with extensive laminectomy and emergency actions favoring partial

The author gives here some considerations about A. Vesalius through his life and his works as a surgeon. He was the father of the anatomical revolution against Galen but was also an eminent clinician and surgeon. He was immediately able to adapt his surgical practice whenever the promising methodology was identified (see Consilia). The author concludes with a critical analysis of the Chirurgia magna in septem libros digesta attributed to A. Vesalius.

To identify the risk factors for surgical site infection after cesarean delivery in a rural area in eastern Burkina Faso. A matched case-control study was conducted in Fada N'Gourma Regional Hospital Center and the Diapaga Medical Center with Surgical Antenna using data from 2011-2014. A total of 99 cases of surgical site infection after cesarean delivery were included in the study. Each case was matched with a control patient similar for age, admission date, and facility where the cesarean took place. Risk factors were identified using conditional logistic regression. Multivariate analysis identified hyperthermia at admission (OR 2.37; P=0.035), the presence of caput succedaneum in newborns (OR 7.07; P=0.001), and difficult delivery (OR 3.69; P=0. 019) as risk factors for surgical site infection. Provision of quality prenatal care, use of the partograph during labor, and the responsiveness of health workers during labor can reduce surgical site infection after cesarean delivery.

Our goals were to evaluate the risk factors predisposing to saphenous vein harvest surgical site infection (HSSI), the microbiology implicated, associated outcomes including 30-day mortality, and identify opportunities for prevention of infection. All patients undergoing coronary artery bypass grafting (CABG) procedures from January 2000 through September 2004 were included. Data were collected on preoperative, intraoperative, and postoperative factors, in addition to microbiology and outcomes. Eighty-six of 3578 (2.4%) patients developed HSSI; 28 (32.6%) of them were classified as deep. The median time to detection was 17 (range, 4-51) days. An organism was identified in 64 (74.4%) cases; of them, a single pathogen was implicated in 50 (78%) cases. Staphylococcus aureus was the most frequently isolated pathogen: 19 (38% [methicillin-susceptible S aureus (MSSA) = 12, methicillin-resistant S aureus (MRSA) = 7]). Gram-negative organisms were recovered in 50% of cases, with Pseudomonas aeruginosa predominating in 11 (22%) because of a single pathogen. Multiple pathogens were identified in 14 (22%) cases. The 30-day mortality was not significantly different in patients with or without HSSI. Multivariate analysis showed age, diabetes mellitus, obesity, congestive heart failure, renal insufficiency, and duration of surgery to be associated with increased risk. Diabetes mellitus, obesity, congestive heart failure, renal insufficiency, and duration of surgery were associated with increased risk for HSSI. S aureus was the most frequently isolated pathogen.

The discopathy disease has an important incidence all over the world affecting more men than women and is influenced by social factors. The treatment has often surgical indication. The operating techniques on one hand are dependent on the equipment, instruments and expertise and on the other hand they are related to the specificity of the case, surgeon's inspiration etc. These factors are influencing the postoperative patient evolution.

To review elements of an ergonomic operating room environment and describe common ergonomic errors in surgeon posture during laparoscopic and robotic surgery. Descriptive video based on clinical experience and a review of the literature (Canadian Task Force classification III). Community teaching hospital affiliated with a major teaching hospital. Gynecologic surgeons. Demonstration of surgical ergonomic principles and common errors in surgical ergonomics by a physical therapist and surgeon. The physical nature of surgery necessitates awareness of ergonomic principles. The literature has identified ergonomic awareness to be grossly lacking among practicing surgeons, and video has not been documented as a teaching tool for this population. Taking this into account, we created a video that demonstrates proper positioning of monitors and equipment, and incorrect and correct ergonomic positions during surgery. Also presented are 3 common ergonomic errors in surgeon posture: forward head position, improper shoulder elevation, and pelvic girdle asymmetry. Postural reset and motion strategies are demonstrated to help the surgeon learn techniques to counterbalance the sustained and awkward positions common during surgery that lead to muscle fatigue, pain, and degenerative changes. Correct ergonomics is a learned and practiced behavior. We believe that video is a useful way to facilitate improvement in ergonomic behaviors. We suggest that consideration of operating room setup, proper posture, and practice of postural resets are necessary components for a longer, healthier, and pain-free surgical career.

BACKGROUND: The aim of this study was to analyze the factors that influence the advancement and the career choices of doctors and medical students. METHODS: Using the combined databases of the iformix and surgent websites, 450 doctors and medical students were invited to complete an internet-based survey. Surgent (http:\\/\\/www.surgent.ie) and iformix (http:\\/\\/www.iformix.com) are two free internet services administered by the authors. Surgent is a medical educational website, while iformix facilitates the online submission of abstracts to surgical and medical conferences across Britain and Ireland. The combined database of these two websites is approximately 4500 entries. Four hundred and fifty users represented a 10% sample based on an expected 40%-45% response rate. This was anticipated to yield between 180 and 202 respondents, statistically sufficient to analyze the data. A detailed Likert scale assessed the importance of "academic," "clinical," and "lifestyle" factors in determining career choice and progression. Analysis included descriptive statistics and inferential testing. RESULTS: Fifty percent (N = 222) of surveys were returned; 142 men and 78 women. Thirty-seven percent of respondents were Irish, 28% British, and 35% non-European. Fifteen percent were undergraduates, 4% interns, 12% had 2-4 years of clinical experience, while 69% had completed more than 4 years. Fifty-six percent had decided upon a career in general surgery. Overall, the most important factors for career choice were intellectual challenge (95%), academic opportunities (61%), and research opportunities(54%). Doctors with more than 4 years of experience deemed duration of training (p = 0.002), lifestyle during training (p = 0.02), and stress (0.005) as less important factors when considering career choice. Correlation analyses demonstrated that prestige (p = 0.002), patient relationships (p = 0.006), and advice from friends or family (p = 0.01) were more important influencing factors

Prescription of preoperatory imaging assessment prior to planned breast reconstruction surgery (reduction or augmentation mastoplasty, correction of congenital breast asymmetry) is poorly codified. The objective of this study was to analyze the attitudes of French radiologists and plastic surgeons with regard to prescription of preoperative imaging in the framework of non-oncologic breast surgery. This is a descriptive and comparative observational study involving two groups, one consisting of 50 plastic surgeons (P) and the other of 50 radiologists (R) specialized in breast imaging. A questionnaire was handed out to radiologists during a conference on breast imaging at the Institut Gustave-Roussy in Paris (France) held on 17th December 2012. The same questionnaire was handed out to plastic surgeons at the National Congress of the French Society of Plastic and Reconstructive Surgery (SOFCPRE) held on 19th, 20th and 21st November 2012, also in Paris (France). The questionnaire focused on prescription of preoperative and postoperative imaging evaluation for non-oncologic breast surgery in patients with no risk factors for breast cancer or clinically identified indications. Forty-six percent of the plastic surgeons considered an imaging exam to be recent when it had been carried out over the previous 6 months, while 40% of the radiologists set the figure at 1 year. Clinical breast density exerted no influence on 92% of the plastic surgeons and 98% of the radiologists. A majority of the plastic surgeons would prescribe a preoperative exam regardless of age (57% for breast reduction, 61% for breast implant placement and 61% for surgical correction of asymmetry) while the radiologists would prescribe exams mainly for patients over 40 years (50% for reduction, 44% for augmentation, 49% for asymmetry correction). The plastic surgeons would prescribe either ultrasound or mammograms (59% for reduction, 72% for augmentation, 66% for asymmetry correction) while radiologists
Full Text Available Sternotomy is the gold standard incision for cardiac surgeons but it is also used in thoracic surgery especially for mediastinal, tracheal and main stem bronchus surgery. The surgical technique is well established and identification of the correct anatomic landmarks, midline tissue preparation, osteotomy and bleeding control are important steps of the procedure. Correct sternal closure is vital for avoiding short- and long-term morbidity and mortality. The two sternal halves have to be well approximated to facilitate healing of the bone and to avoid instability, which is a risk factor for wound infection. New suture materials and techniques would be expected to be developed to further improve the patients evolution, in respect to both immediate postoperative period and long-term morbidity and mortality

Surgical patients are at particular risk of healthcare-associated infection (HCAI) due to the presence of a surgical site leading to surgical site infection (SSI), and because of the need for intravascular access resulting in catheter-related bloodstream infection (CRBSI). A two-year initiative commenced with an initial audit of surgical practice; this was used to inform the development of a targeted educational initiative by surgeons specifically for surgical trainees. Parameters assessed during the initial audit and a further audit after the educational initiative were related to intra- and postoperative aspects of the prevention of SSIs, as well as care of peripheral venous catheters (PVCs) in surgical patients. The proportion of prophylactic antibiotics administered prior to incision across 360 operations increased from 30.0% to 59.1% (P<0.001). Surgical site dressings were observed in 234 patients, and a significant decrease was found in the percentage of dressings that were tampered with during the initial 48h after surgery (16.5% vs 6.2%, P=0.030). In total, 574 PVCs were assessed over the two-year period. Improvements were found in the proportion of unnecessary PVCs in situ (37.9% vs 24.4%, P<0.001), PVCs in situ for >72h (10.6% vs 3.1%, P<0.001) and PVCs covered with clean and intact dressings (87.3% vs 97.6%, P<0.001). Significant improvements in surgical practice were established for the prevention of SSI and CRBSI through a focused educational programme developed by and for surgeons. Potentially, other specific measures may also be warranted to achieve further improvements in infection prevention in surgical practice.

Full Text Available Abstract Background Abdominal surgical site infections are among the most common complications of inpatient admissions and have serious consequences for outcomes and costs. Different risk factors may be involved, including age, sex, nutrition and immunity, prophylactic antibiotics, operation type and duration, type of shaving, and secondary infections. This study aimed to determine the risk factors affecting abdominal surgical site infections and their incidence at Imam Khomeini, a major referral teaching hospital in Iran. Methods Patients (n = 802 who had undergone abdominal surgery were studied and the relationships among variables were analyzed by Student's t and Chi-square tests. The subjects were followed for 30 days and by a 20-item questionnaire. Data were collected through pre- and post-operative examinations and telephone follow-ups. Results Of the 802 patients, 139 suffered from SSI (17.4%. In 40.8% of the cases, the wound was dirty infected. The average age for the patients was 46.7 years. The operations were elective in 75.7% of the cases and 24.7% were urgent. The average duration of the operation was 2.24 hours, the average duration of pre-operative hospital stay 4.31 days and the average length of (pre- and post-operation hospital stay 11.2 days. Three quarters of the cases were shaved 12 hours before the operation. The increased operation time, increased bed stay, electivity of the operation, septicity of the wound, type of incision, the administration of prophylactic antibiotic, type of operation, background disease, and the increased time lapse between shaving and operation all significantly associated with SSI with a p-value less than 0.001. Conclusion In view of the high rate of SSI reported here (17.4% compared with the 14% quoted in literature, this study suggests that by reducing the average operation time to less than 2 hours, the average preoperative stay to 4 days and the overall stay to less than 11 days, and

Background Adrenocortical carcinoma (ACC) is a rare disease with a poor prognosis. Given the lack of data on readmission after resection of ACC, the objective of the current study was to define the incidence of readmission, as well as identify risk factors associated with readmission among patients with ACC who underwent surgical resection. Methods Two hundred nine patients who underwent resection of ACC between January 1993 and December 2014 at 1 of 13 major centers in the USA were identified. Demographic and clinicopathological data were collected and analyzed relative to readmission. Results Median patient age was 52 years, and 62 % of the patients were female. Median tumor size was 12 cm, and the majority of patients had an American Society of Anesthesiologists (ASA) class of 3–4 (n=85, 56 %). The overall incidence of readmission within 90 days from surgery was 18 % (n=38). Factors associated with readmission included high ASA class (odds ratio (OR), 4.88 (95 % confidence interval (CI), 1.75–13.61); P=0.002), metastatic disease on presentation (OR, 2.98 (95 % CI, 1.37–6.46); P=0.006), EBL (>700 mL: OR, 2.75 (95 % CI, 1.16–6.51); P=0.02), complication (OR, 1.91 (95 % CI, 1.20–3.05); P=0.007), and prolonged length of stay (LOS; ≥9 days: OR, 4.12 (95 % CI, 1.88–9.01); P<0.001). On multivariate logistic regression, a high ASA class (OR, 4.01 (95 % CI, 1.44–11.17); P=0.008) and metastatic disease on presentation (OR, 3.44 (95 % CI, 1.34–8.84); P=0.01) remained independently associated with higher odds of readmission. Conclusion Readmission following surgery for ACC was common as one in five patients experienced a readmission. Patients with a high ASA class and metastatic disease on presentation were over four and three times more likely to be readmitted after surgical treatment for ACC, respectively. PMID:26286367

: Antibiotic resistance continues to receive national attention as a leading public health threat. In 2015, President Barack Obama proposed a National Action Plan to Combat Antibiotic-Resistant Bacteria to curb the rise of "superbugs," bacteria resistant to antibiotics of last resort. Whereas many antibiotics are prescribed appropriately to treat infections, there continue to be a large number of inappropriately prescribed antibiotics. Although much of the national attention with regards to stewardship has focused on primary care providers, there is a significant opportunity for surgeons to embrace this national imperative and improve our practices. Local quality improvement efforts suggest that antibiotic misuse for surgical disease is common. Opportunities exist as part of day-to-day surgical care as well as through surgeons' interactions with nonsurgeon colleagues and policy experts. This article discusses the scope of the antibiotic misuse in surgery for surgical patients, and provides immediate practice improvements and also advocacy efforts surgeons can take to address the threat. We believe that surgical antibiotic prescribing patterns frequently do not adhere to evidence-based practices; surgeons are in a position to mitigate their ill effects; and antibiotic stewardship should be a part of every surgeons' practice.

Risk factors for surgical site infection (SSI) after liver transplantation and outcomes associated with these infections have not been assessed using consensus surveillance and optimal analytic methods. A cohort study was performed of patients undergoing first liver transplantation at Mayo Clinic, Jacksonville, Florida, in 2003 and 2004. SSIs were identified by definitions and methods of the National Nosocomial Infections Surveillance System. Measures of known or suspected risk factors for SSI, graft loss, or death were collected on all patients. Associations of SSI with these factors and also with the primary composite endpoint of graft loss or death within 1 year of liver transplantation were examined using Cox proportional hazards models; relative risks (RRs) were estimated along with 95% confidence intervals (CIs). Of 370 patients, 66 (18%) had SSI and 57 (15%) died or sustained graft loss within 1 year after liver transplantation. Donor liver mass-to-recipient body mass ratio of less than 0.01 (RR 2.56; 95% CI 1.17-5.62; P=0.019) and increased operative time (RR 1.19 [1-hr increase]; 95% CI 1.03-1.37; P=0.018) were associated with increased SSI risk. SSI was associated with increased risk of death or graft loss within the first year after liver transplantation (RR 3.06; 95% CI 1.66-5.64; P<0.001). SSI is associated with increased risk of death or graft loss during the first year after liver transplantation. Increased operative time and decreased donor liver-to-recipient body mass ratio showed evidence of association with SSI.

The objective of the study is to study surgical site infection (SSI) rates and risk factors in a pediatric population. We conducted a prospective cohort study to estimate the SSI rate at a national pediatric referral center, covering all patients managed at the Orthopedic Surgery Department of the Niño Jesús Children's University Teaching Hospital from January 2010 through December 2012. Risk factors and antibiotic prophylaxis were monitored. A comparison between Spanish and US data was performed, with a breakdown by National Nosocomial Infection Surveillance risk indices. We also conducted a comparative study of SSI rates from 2010 to 2012 to assess the impact of the epidemiologic surveillance system. The study population of 1079 patients had a SSI rate of 2.8%. SSI rates were calculated for spinal fusion and other musculoskeletal procedures according to the National Nosocomial Infection Surveillance risk index. In the case of other musculoskeletal procedures, our SSI rates were 0.8 times lower than the overall Spanish rate, but higher than US rates for all risk categories. For spinal fusion procedures, our SSI rates were 1.2 times higher than the Spanish rates and 3.5 times higher than National Nosocomial Infection Surveillance rates. This latter finding should be interpreted with caution because it was based on a small sample. The multivariate analysis indicated that the only predictive factors of SSI were American Society of Anesthesiologists score and age. The surveillance program showed that for clean procedures, SSI incidence decreased from 4% in 2010 to 3.2% in 2011 and to 2.4% in 2012.

To investigate whether operative factors are associated with risk of surgical site infection (SSI) after hernia repair. Retrospective cohort study. Patients Commercially insured enrollees aged 6 months-64 years with International Classification of Diseases, Ninth Revision, Clinical Modification procedure or Current Procedural Terminology, fourth edition, codes for inguinal/femoral, umbilical, and incisional/ventral hernia repair procedures from January 1, 2004, through December 31, 2010. SSIs within 90 days after hernia repair were identified by diagnosis codes. The χ2 and Fisher exact tests were used to compare SSI incidence by operative factors. A total of 119,973 hernia repair procedures were analyzed. The incidence of SSI differed significantly by anatomic site, with rates of 0.45% (352/77,666) for inguinal/femoral, 1.16% (288/24,917) for umbilical, and 4.11% (715/17,390) for incisional/ventral hernia repair. Within anatomic sites, the incidence of SSI was significantly higher for open versus laparoscopic inguinal/femoral (0.48% [295/61,142] vs 0.34% [57/16,524], P=.020) and incisional/ventral (4.20% [701/16,699] vs 2.03% [14/691], P=.005) hernia repairs. The rate of SSI was higher following procedures with bowel obstruction/necrosis than procedures without obstruction/necrosis for open inguinal/femoral (0.89% [48/5,422] vs 0.44% [247/55,720], Poperative factors may facilitate accurate comparison of SSI rates between facilities.

Motor peripheral nerve injury is a rare but serious event after colorectal surgery, and a nationwide study of this complication is lacking. The purpose of this study was to report the incidence, trends, and risk factors of motor peripheral nerve injury during colorectal surgery. The National Surgical Quality Improvement Program database was surveyed for motor peripheral nerve injury complicating colorectal procedures. Risk factors for this complication were identified using logistic regression analysis. The study used a national database. Patients undergoing colorectal resection between 2005 and 2013 were included. The incidence, trends, and risk factors for motor peripheral nerve injury complicating colorectal procedures were measured. We identified 186,936 colorectal cases, of which 50,470 (27%) were performed laparoscopically. Motor peripheral nerve injury occurred in 122 patients (0.065%). Injury rates declined over the study period, from 0.025% in 2006 to nerve injury were younger (mean ± SD; 54.02 ± 15.41 y vs 61.56 ± 15.95 y; p Nerve injury was also associated with longer operative times (277.16 ± 169.79 min vs 176.69 ± 104.80 min; p nerve injury (OR = 1.04 (95% CI, 1.03-1.04)), whereas increasing age was associated with a protective effect (OR = 0.80 (95% CI, 0.71-0.90)). This study was limited by its retrospective nature. Motor peripheral nerve injury during colorectal procedures is uncommon (0.065%), and its rate declined significantly over the study period. Prolonged operative time is the strongest predictor of motor peripheral nerve injury during colorectal procedures. Instituting and documenting measures to prevent nerve injury is imperative; however, special attention to this complication is necessary when surgeons contemplate long colorectal procedures.

Proper and adequate documentation in operation notes is a basic tool of clinical practice with medical and legal implications. An audit was done to ascertain if oral and maxillofacial surgery operative notes in an Indian public sector hospital adhered to the guidelines published by the Royal College of Surgeons England. Fifty randomly selected operative notes were evaluated against the guidelines by RCS England with regards to the essential generic components of an operation note. Additional criteria relevant to oral and Maxillofacial Surgery were also evaluated. Changes were introduced in the form of Oral and Maxillofacial Surgery specific consent forms, diagram sheets and a computerized operation note proforma containing all essential and additional criteria along with prefilled template of operative findings. Re-audit of 50 randomly selected operation notes was performed after a 6 month period. In the 1st audit cycle, excellent documentation ranging from 94 to 100 % was seen in 9 essential criteria. Unsatisfactory documentation was observed in criteria like assistant name, date of surgery. Most consent forms contained abbreviations and some did not provide all details. Additional criteria specific to Oral and Maxillofacial Surgery scored poorly. In the 2nd Audit for loop completion, excellent documentation was seen in almost all essential and additional criteria. Mean percentage of data point inclusion improved from 84.6 to 98.4 % (0.001< P value <0.005). The use of abbreviations was seen in only 6 notes. Regular audits are now considered a mandatory quality improvement process that seeks to improve patient care and outcomes. To the best of our knowledge, this is the first completed audit on operation notes documentation in Oral and Maxillofacial Surgery from India. The introduction of a computerized operation note proforma showed excellent improvement in operation note documentation. Surgeons can follow the RCS guidelines to ensure standardization of
CONCLUSION: Stage did not clearly predict surgical pathologic risk factors, a result of uncertainty of clinical staging. Without surgery, it is impossible to determine the actual limits of the disease with the tests available at this time.

There is a complete paucity of literature for left-handed surgeons. Some studies revealed that left-handed surgical residents have lesser operating skills and some surgeons have considered leaving surgery at some point in their career owing to laterality-related frustrations. Most important, whereas minimally invasive surgical techniques have had a profound impact on the treatment of diseased gallbladder, these procedures do not eliminate laterality related to the discomfort of left-handed surgeons. Usually, left-handed surgeons must teach themselves a procedure. They must make modifications and learn some technical tips to make a more comfortable, convenient, and safe intervention. The aim of this study was to describe some modifications made by a left-handed surgeon to perform 52 safe laparoscopic cholecystectomies with standard right-handed instruments in our hospital. These surgical steps could be used in a reproducible way to minimize the recurring difficulties of left-handed learners in a surgical residency program.

Surgical site infection (SSI) associated with instruments remains a serious and common complication in patients who undergo total en bloc spondylectomy (TES). It is very important that the risk factors for SSI are known to prevent it. The purpose of the study was to identify independent risk factors for SSI after TES and evaluate the positive effect of iodine-supported spinal instruments in the prevention of SSI after TES. This is a retrospective clinical study. One hundred twenty-five patients who underwent TES for vertebral tumor were evaluated. Incidence rate of SSI, risk factors for SSI after TES, and safety of iodine-supported spinal instruments were the outcome measures. Risk factors for SSI were analyzed using logistic regression. In recent 69 patients with iodine-supported spinal instruments, the thyroid hormone levels in the blood were examined to confirm if iodine from the implant influenced thyroid function. Postoperative radiological evaluations were performed regularly. The rate of SSI was 6.4% (8/125 patients). By multivariate logistic regression, combined anterior and posterior approach and nonuse of iodine-supported spinal instruments were associated with an increased risk of SSI. The rate of SSI without iodine-supported spinal instruments was 12.5%, whereas the rate with iodine-supported spinal instruments was 1.4%. This difference was statistically significant. There were no detected abnormalities of thyroid gland function with the use of iodine-supported instruments. Among the 69 patients with iodine-supported spinal instruments, 2 patients required additional surgery because of instrument failure. However, there were no obvious involvements with the use of iodine-supported spinal instruments. This study identified combined anterior and posterior approach and nonuse of iodine-supported spinal instruments to be independent risk factors for SSI after TES. Iodine-supported spinal instrument was extremely effective for prevention of SSI in patients
Full Text Available Background: Rotator cuff tendon tear injury is one of the most frequently seen orthopaedic conditions, and surgical repair of rotator cuff tears is a common procedure. The purpose of the present study was to determine the results of full-thickness rotator cuff repair and to look for predictors of outcomes. Methods: we studied 27 patients (17 men and 10 women with a mean age of 57.7 years who underwent open rotator cuff repair surgery for full-thickness tear between 2001 and 2005 at the Imam Khomeini Hospital and were subsequently followed-up for 6 and 12 months after surgery. The shoulder function was assessed by Constant classification and factors potentially associated with outcomes were Results: The mean of preoperative Constant score (CS was 45.8 ± 14.1 after 12 months, 6 patients (22.2% had good results and 21 patients (77.8% had excellent result according to CS. Pain relief was generally satisfactory. Using multiple regression analysis, treatment was significantly correlated preoperative CS and acromio-humeral interval (AHI however, no correlation was found between the result of the treatment and pretreatment atrophy, tear size, acromial morphology, preoperative symptom duration and age. Conclusion: In this study, a standard rotator cuff repair technique reduced pain severity and was associated with good results, however larger studies are necessary to define the long-term outcome of this procedure.

The practice of general surgery in smaller Canadian communities requires a broad scope of training, and recently the Royal College of Physicians and Surgeons of Canada introduced training requirements to meet the needs of these communities. The traditional role of physicians and surgeons in relation to the hospital boards is changing, with the development of regional health boards. Surgeons must be adaptable to these changes while striving to preserve the standards of surgical care in the new environment. The 1990 Canadian Medical Association manpower studies indicated that there will soon be a major shortage of general surgeons in Canada. In 1990, 48% of general surgeons in Canada were over 55 years of age. In communities with a population of 10,000 or less, there were relatively more general surgeons than other specialists, but, again, they were proportionately older. Recruitment to general surgery is a concern. A survey of 205 residents obtaining the Royal College fellowship in surgery between 1991 and 1993 revealed that 107 took post-fellowship training; of these, 46 developed academic careers, 17 became community surgeons and 44 were lost to surgical practice (they went into cardiac surgery or emigrated). Ninety-eight did not take further training; of these, 5 developed academic careers, 87 chose community practice and 6 emigrated. The role of the general practitioner in providing surgical services in remote areas was the topic of discussion between the Canadian Association of General Surgeons (CAGS), the Royal College and the College of Family Physicians of Canada. Guidelines were developed and approved by the CAGS.(ABSTRACT TRUNCATED AT 250 WORDS)

Surgeon burnout compromises the quality of life of physicians and the delivery of care to patients. Burnout rates and interpretation of the Maslach Burnout Inventory (MBI) complicates the interpretation of surgeon burnout. The purpose of this study is to apply a standardized interpretation of severe surgeon burnout termed, "burnout syndrome" to analyze inherent variation within surgical specialties. A systematic literature search was performed using MEDLINE, PsycINFO, and EMBASE to identify studies reporting MBI data by surgical specialty. Data extraction was performed to isolate surgeon specific data. A meta-analysis was performed. A total of 16 cross-sectional studies were included in this meta-analysis, totaling 3581 subjects. A random effects model approximated burnout syndrome at 3.0% (95% CI: 2.0%-5.0%; I 2 = 78.1%). Subscale analysis of emotional exhaustion, depersonalization, and personal accomplishment indicated subscale burnout in 30.0% (CI: 25.0%-36.0%; I 2 = 93.2%), 34.0% (CI: 25.0%-43.0%; I 2 = 96.9%), and 25.0% (CI: 18.0%-32.0%; I 2 = 96.5%) of surgeons, respectively. Significant differences (p burnout termed "burnout syndrome," although surgeon burnout may occur in up to 34% of surgeons, characterized by high burnout in 1 of 3 subscales. Surgical specialties have significantly different rates of burnout subscales. Future burnout studies should target the specialty-specific level to understand inherent differences in an effort to better understand methods of improving surgeon burnout.

Burnout is common in professions such as medicine in which employees have frequent and often stressful interpersonal interactions where empathy and emotional control are important. Burnout can lead to decreased effectiveness at work, negative health outcomes, and less job satisfaction. A relationship between burnout and job satisfaction is established for several types of physicians but is less studied among surgeons who treat musculoskeletal conditions. We asked: (1) For surgeons treating musculoskeletal conditions, what risk factors are associated with worse job dissatisfaction? (2) What risk factors are associated with burnout symptoms? Two hundred ten (52% of all active members of the Science of Variation Group [SOVG]) surgeons who treat musculoskeletal conditions (94% orthopaedic surgeons and 6% trauma surgeons; in Europe, general trauma surgeons do most of the fracture surgery) completed the Global Job Satisfaction instrument, Shirom-Malamed Burnout Measure, and provided practice and surgeon characteristics. Most surgeons were male (193 surgeons, 92%) and most were academically employed (186 surgeons, 89%). Factors independently associated with job satisfaction and burnout were identified with multivariable analysis. Greater symptoms of burnout (β, -7.13; standard error [SE], 0.75; 95% CI, -8.60 to -5.66; p job satisfaction. Having children (β, -0.45; SE, 0.0.21; 95% CI, -0.85 to -0.043; p = 0.030; adjusted R(2), 0.046) was the only factor independently associated with fewer symptoms of burnout. Among an active research group of largely academic surgeons treating musculoskeletal conditions, most are satisfied with their job. Efforts to limit burnout and job satisfaction by optimizing engagement in and deriving meaning from the work are effective in other settings and merit attention among surgeons. Level II, prognostic study.

STRUCTURED ABSTRACT Background Recent data establishes a strong link between peer video ratings of surgical skill and clinical outcomes with laparoscopic gastric bypass. Whether skill for one bariatric procedure can predict outcomes for another, related procedure is unknown. Methods Twenty surgeons voluntarily submitted videos of a standard laparoscopic gastric bypass procedure, which was blindly rated by 10 or more peers using a modified version of the Objective Structured Assessment of Technical Skills (OSATS). Surgeons were divided into quartiles for skill in performing gastric bypass and their outcomes within 30 days after sleeve gastrectomy were compared. Multivariate logistic regression analysis was utilized to adjust for patient risk factors. Results Surgeons with skill ratings in the top (n=5), middle (n=10, middle two combined), and bottom (n=5) quartiles for laparoscopic gastric bypass had similar rates of surgical and medical complications following laparoscopic sleeve gastrectomy (top 5.7%, middle 6.4%, bottom 5.5%, p=0.13). Furthermore, surgeon skill ratings did not correlate with rates of reoperation, readmission and emergency department visits. Top rated surgeons had significantly faster operating room times for sleeve gastrectomy (top 76 min, middle 90 min, bottom 88 min; plaparoscopic gastric bypass do not predict outcomes with laparoscopic sleeve gastrectomy. Evaluation of surgical skill with one procedure may not apply to other related procedures and may require independent assessment of surgical technical proficiency. PMID:27324569

The involvement of healthy living donors and the degree of technical difficulty make adult living donor liver transplantation (LDLT) different from any other surgical procedure. We surveyed 100 liver transplant surgeons to assess their views on the complex issues raised by LDLT. Data were collected at meetings on LDLT and by electronic mail. The study instrument was divided into general, donor, surgeon, recipient, and donor and recipient issues. Subjects provided the projected 1-year survival threshold that they would require for the recipient before they would perform LDLT. They listed the three topics that they thought were most critical for transplant fellows to know about LDLT. A majority agreed that transplant programs have a duty to their patients to offer LDLT, that the increasing success of the procedure will expand indications for liver transplantation, and that the risk to the donor causes them a moral dilemma. There was more divergence of opinion regarding who should have the final say about a potential donor's candidacy, whether it is difficult for donors to comprehend the risks of the procedure, and whether repeat cadaveric transplantations should be offered for failed LDLT performed for extended indications. Surgeons' median recipient survival threshold was a conservative 79%. Priorities for educating trainees focused on understanding complications and risks, technical factors, and ethical concerns such as putting the donor first. In conclusion, the findings of this survey indicate that transplant surgeons are working to balance their moral imperative to provide life-saving therapy for transplantation candidates with the risks posed to living donors.

The importance of leadership is recognized in surgery, but the specific impact of leadership style on team behavior is not well understood. In other industries, leadership is a well-characterized construct. One dominant theory proposes that transactional (task-focused) leaders achieve minimum standards and transformational (team-oriented) leaders inspire performance beyond expectations. We videorecorded 5 surgeons performing complex operations. Each surgeon was scored on the Multifactor Leadership Questionnaire, a validated method for scoring transformational and transactional leadership style, by an organizational psychologist and a surgeon researcher. Independent coders assessed surgeons' leadership behaviors according to the Surgical Leadership Inventory and team behaviors (information sharing, cooperative, and voice behaviors). All coders were blinded. Leadership style (Multifactor Leadership Questionnaire) was correlated with surgeon behavior (Surgical Leadership Inventory) and team behavior using Poisson regression, controlling for time and the total number of behaviors, respectively. All surgeons scored similarly on transactional leadership (range 2.38 to 2.69), but varied more widely on transformational leadership (range 1.98 to 3.60). Each 1-point increase in transformational score corresponded to 3 times more information-sharing behaviors (p < 0.0001) and 5.4 times more voice behaviors (p = 0.0005) among the team. With each 1-point increase in transformational score, leaders displayed 10 times more supportive behaviors (p < 0.0001) and displayed poor behaviors 12.5 times less frequently (p < 0.0001). Excerpts of representative dialogue are included for illustration. We provide a framework for evaluating surgeons' leadership and its impact on team performance in the operating room. As in other fields, our data suggest that transformational leadership is associated with improved team behavior. Surgeon leadership development, therefore, has the potential to
Cost and logistics of implementing a tissue-based American College of Surgeons/Association of Program Directors in Surgery surgical skills curriculum for general surgery residents of all clinical years.

The cost and logistics of deploying the American College of Surgeons (ACS)/Association of Program Directors in Surgery (APDS) National Technical Skills Curriculum across all training years are not known. This information is essential for residency programs choosing to adopt similar curricula. A task force evaluated the authors' institution's existing simulation curriculum and enhanced it by implementing the ACS/APDS modules. A 35-module curriculum was administered to 35 general surgery residents across all 5 clinical years. The costs and logistics were noted, and resident satisfaction was assessed. The annual operational cost was $110,300 ($3,150 per resident). Cost per module, per resident was $940 for the cadaveric module compared with $220 and $240 for dry simulation and animal tissue-based modules, respectively. Resident satisfaction improved from 2.45 to 4.78 on a 5-point, Likert-type scale after implementing the ACS/APDS modules. The ACS/APDS skills curriculum was implemented successfully across all clinical years. Cadaveric modules were the most expensive. Animal and dry simulation modules were equivalent in cost. The addition of tissue-based modules was associated with high satisfaction. Copyright © 2014 Elsevier Inc. All rights reserved.

On April 6, 1917, the United States declared war on Germany and entered what was then called the Great War. Among the first officers sent to Europe were 21 orthopaedic surgeons in the so-called First Goldthwait Unit. Prior to the war, orthopaedics had been a nonoperative "strap-and-buckle" specialty that dealt primarily with infections, congenital abnormalities, and posttraumatic deformity. The Great War changed all of that forever, creating a new surgical specialty with emphasis on acute treatment, prevention of deformity, restoration of function, and rehabilitation.

To explore how the 2 most important components of surgical performance--speed and accuracy-are influenced by different forms of stress and what the impact of music is on these factors. On the basis of a recently published pilot study on surgical experts, we designed an experiment examining the effects of auditory stress, mental stress, and music on surgical performance and learning and then correlated the data psychometric measures to the role of music in a novice surgeon's life. Thirty-one surgeons were recruited for a crossover study. Surgeons were randomized to 4 simple standardized tasks to be performed on the SurgicalSIM VR laparoscopic simulator (Medical Education Technologies, Inc, Sarasota, FL), allowing exact tracking of speed and accuracy. Tasks were performed under a variety of conditions, including silence, dichotic music (auditory stress), defined classical music (auditory relaxation), and mental loading (mental arithmetic tasks). Tasks were performed twice to test for memory consolidation and to accommodate for baseline variability. Performance was correlated to the brief Musical Experience Questionnaire (MEQ). Mental loading influences performance with respect to accuracy, speed, and recall more negatively than does auditory stress. Defined classical music might lead to minimally worse performance initially but leads to significantly improved memory consolidation. Furthermore, psychologic testing of the volunteers suggests that surgeons with greater musical commitment, measured by the MEQ, perform worse under the mental loading condition. Mental distraction and auditory stress negatively affect specific components of surgical learning and performance. If used appropriately, classical music may positively affect surgical memory consolidation. It also may be possible to predict surgeons' performance and learning under stress through psychological tests on the role of music in a surgeon's life. Further investigation is necessary to determine the

Our recent publication demonstrated that unprofessional behavior on Facebook is common among surgical residents. In the formulation of standards and curricula to address this issue, it is important that surgical faculty lead by example. Our current study refocuses on the Facebook profiles of faculty surgeons involved in the education of general surgery residents. The American College of Surgeons (ACS) web site was used to identify general surgery residencies located in the Midwest. Departmental web sites were then searched to identify teaching faculty for the general surgery residency. Facebook was then searched to determine which faculty had profiles available for viewing by the general public. Profiles were then placed in 1 of the 3 following categories: professional, potentially unprofessional, or clearly unprofessional. A chi-square test was used to determine significance. In all, 57 residency programs were identified on the ACS web site, 100% of which provided an institutional web site listing the surgical faculty. A total of 758 general surgery faculty were identified (133 women and 625 men), of which 195 (25.7%) had identifiable Facebook accounts. In all, 165 faculty (84.6%) had no unprofessional content, 20 (10.3%) had potentially unprofessional content, and 10 (5.1%) had clearly unprofessional content. Inter-rater reliability was good (88.9% agreement, κ = 0.784). Clearly unprofessional behavior was found only in male surgeons. For male surgeons, clearly unprofessional behavior was more common among those in practice for less than 5 years (p = 0.031). Alcohol and politics were the most commonly found variables in the potentially unprofessional group. Inappropriate language and sexually suggestive material were the most commonly found variables in the clearly unprofessional group. Unprofessional behavior on Facebook is less common among surgical faculty compared with surgical residents. However, the rates remain unacceptably high, especially among men and

When performing an orthopaedic device implantation, it should be routine practice for the surgeon to ask the patient if he or she has a metal allergy, and more specifically a nickel allergy. Ask the patient about costume jewelry or button reactions. If it is an elective surgery, obtain a confirmatory test with the aid of a dermatologist or allergist. It is recommended to use a non-nickel implant if the surgery is urgent, the patient has a confirmed allergy, or the patient does not want to undergo testing, as these implants are readily available in 2015. Finally, if the patient has a painful joint arthroplasty and all other causes have been ruled out, order a metal allergy test to aid in diagnosis.
Surgeons are increasingly using ultrasonography (US) in their clinical management of patients. However, US is a very user-dependent imaging modality and proper skills of the US operator are needed to ensure quality in patient care. This thesis explores the validity evidence for assessment...... of competence in abdominal and head & neck ultrasonography using the Objective Structured Assessment of Ultrasound Skills (OSAUS) scale. With the use of Messick's unitary framework of validity, five sources of validity evidence were explored: test content, response processes, inter-nal structure, relations...... to other variables, and consequences. Research paper I examined validity evidence for the use of the OSAUS scale to assess physicians' abdominal point-of-care US competence in an experimental setting using patient cases with and without pathological conditions. The RESULTS provided validity evidence...

Systematic literature review. To summarize and evaluate research on factors predictive of progression to surgery after nonoperative treatment for an anterior cruciate ligament (ACL) rupture. Anterior cruciate ligament rupture is a common injury among young, active individuals. Surgical reconstruction is often required for patients who do not regain satisfactory knee function following nonsurgical rehabilitation. Knowledge of factors that predict the need for surgical reconstruction of the ACL would be helpful to guide the decision-making process in this population. A search was performed for studies predicting the need for surgery after nonoperative treatment for ACL rupture in the Embase, MEDLINE (OvidSP), Web of Science, CINAHL, Cochrane Central Register of Controlled Trials, PubMed, and Google Scholar digital databases from inception to October 2013. Two reviewers independently selected the studies and performed a quality assessment. Best-evidence synthesis was used to summarize the evidence of factors predicting the need for surgical reconstruction after nonoperative treatment for an ACL rupture. Seven studies were included, 3 of which were of high quality. Based on these studies, neither sex (strong evidence) nor the severity of knee joint laxity (moderate evidence) can predict whether, soon after ACL injury, a patient will need ACL reconstruction following nonoperative treatment. All other factors identified in this review either had conflicting or only minimal evidence as to their level of association with the need for surgical reconstruction. Noteworthy is that 1 high-quality study reported that the spherical shape of the femoral condyle was predictive of the need for ACL reconstruction. Sex and knee joint laxity tests do not predict the need for ACL reconstruction soon after an ACL rupture. Independent validation in future research will be necessary to establish whether knee shape is a predictive factor. Prognosis, level 1a-.

The present study evaluated patients with diagnosis of surgical site infection (SSI) following cesarean section and their controls to determinate risk factors and impact of antibiotic prophylaxis on this condition. All cesareans performed from January 2009 to December 2012 were evaluated for SSI, based on criteria established by CDC/NHSN. Control patients were determined after inclusion of case patients. Medical records of case and control patients were reviewed and compared regarding sociodemographic and clinical characteristics. Our study demonstrated an association following univariate analysis between post-cesarean SSI and number of internal vaginal examinations, time of membrane rupture, emergency cesarean and improper use of antibiotic prophylaxis. This same situation did not repeat itself in multivariate analysis with adjustment for risk factors, especially with regard to antibiotic prophylaxis, considering the emergency cesarean factor only. The authors of the present study not only question surgical antimicrobial prophylaxis use based on data presented here and in literature, but suggest that the prophylaxis is perhaps indicated primarily in selected groups of patients undergoing cesarean section. Further research with greater number of patients and evaluated risk factors are fundamental for better understanding of the causes and evolution of surgical site infection after cesarean delivery.

While the number of variant Creutzfeldt–Jakob disease (vCJD) cases continues to decline, concern has been raised that transmission could occur directly from one person to another through routes including the transfer of blood and shared use of surgical instruments. Here we firstly present data on the surgical procedures undertaken on vCJD patients prior to onset of clinical symptoms, which supports the hypothesis that cases via this route are possible. We then apply a mathematical framework to assess the potential for self-sustaining epidemics via surgical procedures. Data from hospital episode statistics on the rates of high- and medium-risk procedures in the UK were used to estimate model parameters, and sensitivity to other unknown parameters about surgically transmitted vCJD was assessed. Our results demonstrate that a key uncertainty determining the scale of an epidemic and whether it is self-sustaining is the number of times a single instrument is re-used, alongside the infectivity of contaminated instruments and the effectiveness of cleaning. A survey into the frequency of re-use of surgical instruments would help reduce these uncertainties. PMID:17015298

The present day healthcare system in Germany is rapidly changing, even more so after the introduction of diagnosis-related groups. The basic requirements for every surgeon remain manual skills, a profound clinical knowledge and the ability for clinical decision-making even in difficult situations. However, these key elements of surgical education no longer fulfill the requirements for today's leaders in surgery. New requirements, consisting of administrative duties, strategic decision-making and department management are too complex to be made only intuitively. Nowadays surgeons also need a profound education in management skills and knowledge of economic mechanisms in order to run an efficient, profitable, patient-oriented surgical department. Every surgeon who aims at obtaining a leadership position should acquire the necessary knowledge and skills.

Interprofessional non-technical skills for surgeons in disaster response have not yet been developed. The aims of this study were to identify the non-technical skills required of surgeons in disaster response and training for disaster response and to explore the barriers and facilitators to interprofessional practice in surgical teams responding to disasters. Twenty health professionals, with prior experience in natural disaster response or education, participated in semi-structured in-depth interviews. A qualitative matrix analysis design was used to thematically analyze the data. Non-technical skills for surgeons in disaster response identified in this study included skills for austere environments, cognitive strategies and interprofessional skills. Skills for austere environments were physical self-care including survival skills, psychological self-care, flexibility, adaptability, innovation and improvisation. Cognitive strategies identified in this study were "big picture" thinking, situational awareness, critical thinking, problem solving and creativity. Interprofessional attributes include communication, team-player, sense of humor, cultural competency and conflict resolution skills. "Interprofessionalism" in disaster teams also emerged as a key factor in this study and incorporated elements of effective teamwork, clear leadership, role adjustment and conflict resolution. The majority of participants held the belief that surgeons needed training in non-technical skills in order to achieve best practice in disaster response. Surgeons considerring becoming involved in disaster management should be trained in these skills, and these skills should be incorporated into disaster preparation courses with an interprofessional focus.

Plastic surgeons are often not perceived as hand surgery specialists. Better educating medical students about the plastic surgeon's role in hand surgery may improve the understanding of the field for future referring physicians. The purposes of this study were to assess medical students' understanding of hand surgery specialists and to analyze the impact of prior plastic, orthopedic, and general surgery clinical exposure on this understanding. An online survey including 8 hand-related clinical scenarios was administered to students at a large academic medical center. After indicating training level and prior clinical exposure to plastic surgery or other surgical subspecialties, students selected one or more appropriate surgical subspecialists for management of surgical hand conditions. A response rate of 56.4% was achieved. Prior clinical exposure to plastic, orthopedic, and general surgery was reported by 29%, 43%, and 90% of fourth year students, respectively. Students generally chose at least 1 acceptable specialty for management of hand conditions with improvement over the course of their training (P = 0.008). Overall, students perceived orthopedic surgeons as hand specialists more so than plastic and general surgeons. Clinical exposure to plastic surgery increased the selection of this specialty for nearly all scenarios (22%-46%, P = 0.025). Exposure to orthopedic and general surgery was associated with a decrease in selection of plastic surgery for treatment of carpal tunnel and hand burns, respectively. Medical students have a poor understanding of the plastic surgeon's role in hand surgery. If plastic surgeons want to continue to be recognized as hand surgeons, they should better educate medical students about their role in hand surgery. This can be achieved by providing a basic overview of plastic surgery to all medical students with emphasis placed on hand and peripheral nerve surgery.

Surgically implanted transmitters are a common method for tracking animal movements. Immediately following surgical implantation, animals pass through a critical recovery phase when behaviors may deviate from normal and the likelihood of individual survival may be reduced. Therefore, data collected during this period may be censored to minimize bias introduced by surgery-related behaviors or mortality. However, immediate post-release mortalities negate a sampling effort and reduce the amount of data potentially collected after the censoring period. Wildlife biologists should employ methods to support an animalâ€™s survival through this period, but factors contributing to immediate post-release survival have not been formally assessed. We evaluated factors that potentially influenced the immediate post-release survival of 56 spectacled eiders (Somateria fischeri) marked with coelomically implanted satellite transmitters with percutaneous antennae in northern Alaska in 2010 and 2011. We modeled survival through the first 14 days following release and assessed the relative importance and effect of 15 covariates hypothesized to influence survival during this immediate post-release period. Estimated daily survival rate increased over the duration of the immediate post-release period; the probability of mortality was greatest within the first 5 days following release. Our top-ranking model included the effect of 2 blood analytes, pH and hematocrit, measured prior to surgical implantation of a transmitter. We found a positive response to pH; eiders exhibiting acidemia (low pH) prior to surgery were less likely to survive the immediate post-release period. We found a curvilinear response to hematocrit; eiders exhibiting extremely low or high pre-surgery hematocrit were also less likely to survive the immediate post-release period. In the interest of maximizing the survival of marked birds following release, hematological data obtained prior to surgical implantation of
Surgeons are increasingly using ultrasonography (US) in their clinical management of patients. However, US is a very user-dependent imaging modality and proper skills of the US operator are needed to ensure quality in patient care. This thesis explores the validity evidence for assessment of competence in abdominal and head & neck ultrasonography using the Objective Structured Assessment of Ultrasound Skills (OSAUS) scale. With the use of Messick's unitary framework of validity, five sources of validity evidence were explored: test content, response processes, inter-nal structure, relations to other variables, and consequences. Research paper I examined validity evidence for the use of the OSAUS scale to assess physicians' abdominal point-of-care US competence in an experimental setting using patient cases with and without pathological conditions. The RESULTS provided validity evidence of the internal structure of the OSAUS scale and a deci-sion study predicted that four cases and two raters or five cases and one rater could ensure sufficient reliability in future test setups. The relation to other variables was supported by a signifi-cant difference in scores between US experience levels, and by a strong correlation between the OSAUS score and diagnostic accuracy. Research paper II explored the transfer of learning from formal point-of-care US training to performance on patients in a randomized controlled study. The RESULTS supported validity evi-dence regarding OSAUS scores' relation to other variables by demonstrating a significant discrimination in the progress of training-a more refined validity evidence than the relation to difference experience levels. The RESULTS showed that physicians could transfer the skills learned on an ultrasonography course to improved US performance and diagnostic accuracy on patients. However, the RESULTS also indicated that following an initial course, additional training is needed for physicians to achieve competence in US
Full Text Available Abstract Background High astigmatisms are usually induced during corneal suturing subsequent to tissue transplantation or any other surgery which involves corneal suturing. One of the reasons is that the procedure is intimately dependent on the surgeon's skill for suturing identical stitches. In order to evaluate the influence of the irregularity on suturing for the residual astigmatism, a prototype for ophthalmic surgical support has been developed. The final intention of this prototype is to be an evaluation tool for guided suture and as an outcome diminish the postoperative astigmatism. Methods The system consists of hand held ring with 36 infrared LEDs, that is to be projected onto the lachrymal film of the cornea. The image is reflected back through the optics of the ocular microscope and its distortion from the original circular shape is evaluated by developed software. It provides keratometric and circularity measurements during surgery in order to guide the surgeon for uniformity in suturing. Results The system is able to provide up to 23D of astigmatism (32D - 55D range and is ± 0.25D accurate. It has been tested in 14 volunteer patients intraoperative and has been compared to a commercial keratometer Nidek Oculus Hand-held corneal topographer. The correlation factors are 0.92 for the astigmatism and 0.97 for the associated axis. Conclusion The system is potentially efficient for guiding the surgeon on uniformity of suturing, presenting preliminary data indicating an important decrease on the residual astigmatism, from an average of 8D - for patients not submitted to the prototype guidance - to 1.4D - for patients who have actually been submitted to the prototype guidance - after the first 24 hours post-surgery and in the subsequent weeks. It also indicates that the surgeon should achieve circularity greater or equal to 98% in order to avoid postoperative astigmatisms over 1D. Trial Registration Trial registration number: CAAE - 0212.0.004.000-09.

To test the hypothesis that surgeons and their patients underestimate the potential negative impact that permanent hypoparathyroidism has on quality of life (QOL). We used a modified SF-36 assessment tool to compare the perceptions of patients with permanent hypoparathyroidism to the perceptions of control subjects who were given a standardized preoperative statement about the complications of hypoparathyroidism. We also elicited the perceptions of endocrine surgeons regarding the QOL impacts of hypoparathyroidism using a subset of questions from the modified SF-36. A total of 340 postsurgical patients with permanent hypoparathyroidism, 200 controls, and 102 surgeons participated in the study. Both surgeons and controls underestimated the negative impact of hypoparathyroidism on QOL when compared to patients living with permanent hypoparathyroidism. Forty-seven percent of hypoparathyroid patients believed that their health was "much worse" than before surgery, compared with 16% of surgeons (Phypoparathyroid patients also reported far more negative effects on QOL, from interference with social activities, paresthesias, muscle cramping, and medications than were anticipated by surgeons or controls (Phypoparathyroid patients reported a significantly lower mean score compared to the control group (Phypoparathyroidism on patient QOL is consistently and significantly underestimated by surgeons and subjects receiving surgical consultation.

To evaluate the current practice and degree of consensus amongst Australasian surgeons regarding non-surgical management of acute diverticulitis (AD) and to determine whether newer approaches to management are being translated into practice. An online survey was distributed to all Australasian colorectal surgeons and all general surgeons in the Auckland region. Responses were collected over two months and analysed to identify points of consensus and areas of significant difference in opinion between these groups. Responses were received from a total of 99 of 200 (49.5%) colorectal surgeons, and 19 of 36 (52.7%) general surgeons. The Hinchey Classification was the most commonly used measure of disease severity, used by 67 (95.7%) colorectal surgeons and 12 (92.3%) general surgeons. There was lack of consensus around important aspects of AD management, including antibiotic therapy, and use and modality of follow-up imaging. Selective antibiotic therapy and use of anti-inflammatory medication as adjuncts to treatment were practised by a minority of those surveyed. Newer approaches to management were being utilised by some respondents. The lack of consensus regarding management of AD may be a consequence of a paucity of high-level evidence to support specific management approaches, particularly in patients with uncomplicated AD.

Background The importance of leadership is recognized in surgery, but the specific impact of leadership style on team behavior is not well understood. In other industries, leadership is a well-characterized construct. One dominant theory proposes that transactional (task-focused) leaders achieve minimum standards, whereas transformational (team-oriented) leaders inspire performance beyond expectations. Study Design We video-recorded 5 surgeons performing complex operations. Each surgeon was scored on the Multifactor Leadership Questionnaire, a validated method for scoring transformational and transactional leadership style, by an organizational psychologist and a surgeon-researcher. Independent coders assessed surgeons' leadership behaviors according to the Surgical Leadership Inventory and team behaviors (information-sharing, cooperative, and voice behaviors). All coders were blinded. Leadership style (MLQ) was correlated with surgeon behavior (SLI) and team behavior using Poisson regression, controlling for time and the total number of behaviors, respectively. Results All surgeons scored similarly on transactional leadership (2.38-2.69), but varied more widely on transformational leadership (1.98-3.60). Each 1-point increase in transformational score corresponded to 3× more information-sharing behaviors (pleadership and its impact on team performance in the OR. As in other fields, our data suggest that transformational leadership is associated with improved team behavior. Surgeon leadership development therefore has the potential to improve the efficiency and safety of operative care. PMID:26481409

Purpose: Pancreatic neuroendocrine tumors (pNET) are rare neoplasms associated with poor outcomes without resection, and involved surgical margins are associated with a worse prognosis. The role of adjuvant radiotherapy (RT) in these patients has not been characterized. Methods and Materials: We retrospectively evaluated 46 consecutive patients with positive or close (<1 mm) margins after pNET resection, treated from 1983 to 2010, 16 of whom received adjuvant RT. Median RT dose was 50.4 Gy in 1.8-Gy fractions; half the patients received concurrent chemotherapy with 5-fluorouracil or capecitabine. No patients received adjuvant chemotherapy. Cox multivariate analysis (MVA) was used to analyze factors associated with overall survival (OS). Results: Median age at diagnosis was 56 years, and 52% of patients were female. Median tumor size was 38 mm, 57% of patients were node-positive, and 11% had a resected solitary liver metastasis. Patients who received RT were more likely to have larger tumors (median, 54 mm vs. 30 mm, respectively, p = 0.002) and node positivity (81% vs. 33%, respectively, p = 0.002) than those not receiving RT. Median follow-up was 39 months. Actuarial 5-year OS was 62% (95% confidence interval [CI], 41%-77%). In the group that did not receive RT, 3 patients (10%) experienced local recurrence (LR) and 5 patients (18%) developed new distant metastases, while in the RT group, 1 patient (6%) experienced LR and 5 patients (38%) developed distant metastases. Of all recurrences, 29% were LR. On MVA, male gender (adjusted hazard ratio [AHR] = 3.81; 95% CI, 1.21-11.92; p = 0.02) and increasing tumor size (AHR = 1.02; 95% CI, 1.01-1.04; p = 0.007) were associated with decreased OS. Conclusions: Long-term survival is common among patients with involved-margin pNET. Despite significantly worse pathologic features among patients receiving adjuvant RT, rates of LR between groups were similar, suggesting that RT might aid local control, and merits further

Although mortality after elective abdominal aortic aneurysm (AAA) repair has steadily declined, operative mortality for a ruptured AAA (rAAA) remains high. Repair of rAAA at hospitals with a higher elective aneurysm workload has been associated with lower mortality rates irrespective of the mode of treatment. This study sought to determine the association between surgeon specialization and outcomes after rAAA repair. The American College of Surgeons National Surgical Quality Improvement Project database from 2005 to 2010 was used to examine the 30-day mortality and morbidity outcomes of patients undergoing rAAA repair by vascular and general surgeons. Multivariable logistic regression analysis was performed for each death and morbidity, adjusting for all independently predictive preoperative risk factors. Survival curves were compared using the log-rank test. We identified 1893 repairs of rAAAs, of which 1767 (96.1%) were performed by vascular surgeons and 72 (3.9%) were performed by general surgeons. There were no significant differences between patients operated on by general vs vascular surgeons in preoperative risk factors or method of repair. Overall 30-day mortality was 34.3% (649 of 1893). After risk adjustment, mortality was significantly lower in the vascular surgery group compared with the general surgery group (odds ratio [OR], 0.51; 95% confidence interval [CI], 0.30-0.86; P = .011). The risk of returning to the operating room (OR, 0.58; 95% CI, 0.35-0.97; P = .038), renal failure (OR, 0.54; 95% CI, 0.31-0.95; P = .034), and a cardiac complication (OR, 0.53; 95% CI, 0.28-0.99; P = .047) were all significantly less in the vascular surgery group. Despite similar preoperative risk factors profiles, patients who were operated on by vascular surgeons had lower mortality, less frequent returns to the operating room, and decreased incidences of postoperative renal failure and cardiac events. These data add weight to the case for further centralization of

To evaluate the intensity and stability of the red reflex produced by ophthalmic surgical microscopes with nearly-collimated versus focused illumination systems and to assess surgeon preference in a simulated surgical setting. This two-part evaluation consisted of postproduction surgical video analysis of red reflex intensity and a microscope use and preference survey completed by 13 experienced cataract surgeons. Survey responses were based on bench testing and experience in a simulated surgical setting. A microscope with nearly-collimated beam illumination and two focused beam microscopes were assessed. Red reflex intensity and stability were greater with the nearly-collimated microscope illumination system. In the bench testing survey, surgeons reported that the red reflex was maintained over significantly greater distances away from pupillary center, and depth of focus was numerically greater with nearly-collimated illumination relative to focused illumination. Most participating surgeons (≥64%) reported a preference for the microscope with nearly-collimated illumination with regard to red reflex stability, depth of focus, visualization, surgical working distance, and perceived patient comfort. The microscope with nearly-collimated illumination produced a more intense and significantly more stable red reflex and was preferred overall by more surgeons. This is the first report of an attempt to quantify red reflex intensity and stability and to evaluate surgically-relevant parameters between microscope systems. The data and methods presented here may provide a basis for future studies attempting to quantify differences between surgical microscopes that may affect surgeon preference and microscope use in ophthalmic surgery.

Surgical treatment of the medication-related osteonecrosis of the jaw (MRONJ) is still challenging. We examined the outcome of the resection of osteonecrotic lesions and the influence of potential risk factors on the operative success. Seventy six surgical interventions on 40 patients were evaluated in a prospective design with a mean follow-up of 55 weeks. Primary endpoints were: (i) maintenance of the mucosal closure and (ii) decrease of MRONJ stage. Influential variables included preoperative duration, location and diameter of MRONJ, duration and change of antiresorptive therapy, presence of actinomyces species. Only in 27.6% of cases long-term maintenance of the mucosal closure was achieved. However, stage II patients decreased to stage I in 81% after surgery (p < 0.01) and stage III patients improved in 83% of cases (OR = 8.08; p = 0.07). Stage I patients profited only in 38% by surgical intervention. MRONJ recurrence after surgery was associated with extended preoperative MRONJ duration (p = 0.015). There was no significance of further influential variables, but MRONJ of the upper jaw seems prognostically more favorable. Advanced stages of MRONJ benefit from surgical treatment, whereas stage I diseases may also be treated conservatively. An early intervention reduces the risk of recurrence.

To gain an understanding of the relative importance of the nine surgical competencies and their 27 attributes defined by the Royal Australasian College of Surgeons (RACS), which together provide the curriculum framework for today's surgeons. Between 9 August and 30 September 2010, trainees and Fellows of the RACS across Australia and New Zealand actively involved in educational activities rated, via questionnaire, the importance of the RACS competencies (technical expertise, communication, professionalism, medical expertise, judgement and decision making, scholarship and teaching, collaboration and teamwork, management and leadership, and health advocacy) and associated attributes. Importance ranking of competencies and their attributes for surgical education and training. Of 3054 questionnaires distributed, 1834 (60%) were returned. We identified clear priorities in the perceived relative importance of the nine competencies and 27 attributes. The most important attributes were competence, insight, and recognising conditions amenable to surgery; least important were responding to community and cultural needs, supporting others, and maintaining personal health and wellbeing. Key differences were noted for the competency of collaboration and teamwork, which was ranked as more important by trainees than by Fellows. Female trainees and Fellows regarded all attributes as more important than did male trainees and Fellows. In a complex environment with multiple pressures, the priorities of the competencies are important. Trainees and Fellows had a very similar approach to the prioritisation of the attributes. Of concern is the lesser importance given to attributes beyond individual expertise.

Professionalism is now recognized as a core competency of surgical education and is required for certification and licensure. However, best teaching methods remain elusive, because (1) ethical standards are not absolute, and (2) learning and teaching styles vary considerably-both of which are influenced by cultural and generational forces. We sought to compare attitudes, knowledge, and behaviors in fourth year medical students, compared to surgeons in training and practice, focusing on issues related to professionalism in plastic surgery. Fourth year medical students participating in a capstone course (n = 160), surgical residents (n = 219), and attending surgeons (n = 99) at a single institution were asked to complete a questionnaire regarding surgical professionalism. Participants (1) identified components of professionalism, (2) cited examples of unprofessional behavior, (3) ranked the egregiousness of 30 scenarios, and (4) indicated best educational practices. Cohorts were compared using t test and χ, with statistical significance assigned to P values less than 0.05. Compared to surgeons in training or practice, medical students were younger (27.8 vs 38.0 years, P plastic surgery, but differ in their knowledge and observations. Understanding cultural and generational factors may help educators teach and model cognitive and behavioral aspects of professionalism. The fact that some clearly egregious behaviors are not viewed as unethical by individual students, trainees, and surgeons, and that such behavior continues to be observed, indicates the need to improve our efforts in promoting professionalism in plastic surgery.

Dr. Norman Bethune's recognition as a Canadian of renown resulted from his devoted work in China during the late 1930s. He had received a general surgical training, but his personal illness with tuberculosis led him to specialize in thoracic surgery. A surgical program at McGill University under Dr. Edward Archibald, a pioneer thoracic surgeon, was initially successful, but by the mid-1930s Bethune was rejected by McGill and Dr. Archibald. He became chief of thoracic surgery at the Hôpital du Sacré-Coeur outside Montreal. H developed thoracic surgical instruments and wrote numerous scientific papers. The outbreak of civil war in Spain in 1937 attracted Bethune to oppose what he viewed as fascist aggression. He went to Spain, where he established the value of mobile blood banking. On his return to Canada in 1937 he became aware of the escalating war between China and Japan. He joined the Chinese communist forces in northern China and spent 18 months doing Herculean mobile war surgery, while improving the state of medical services in primitive, depressing conditions. He died in 1939 at the age of 49 years of septicemia as a result of accidental laceration of his finger during surgery. The Chinese have venerated Norman Bethune and stimulated his memorialization in Canada. His surgical record can be viewed as mixed in quality, but overall his performance remains impressive for its achievement.

Surgical research in Germany occupies a lower position in international ranking than expected. According to the size of the population, the economic impact, the gross domestic product and the research funding capacity, the impact of German surgical research should be much higher. Reasons are a more intensive commitment to patient care, structural differences and a changing lifestyle in younger doctors in comparison to many leading countries. If the situation is to be improved all factors have to be evaluated and, if possible, changed. Overall, German surgeons are underrepresented as readers and authors in the scientific market, which is mostly in the English language.

Surgeons choose their profession with a strong desire to excel at manual therapeutic skills. Although we mime our mentors, we have often received the torch of technique in the absence of a systematic program to optimally develop our manual dexterity. The operating room is the ultimate arena to refine one's technical ability, but a surgical skills laboratory should assume increasing importance in introducing the trainee to the many nuances of the fine manual motor skills necessary for optimal surgical technique. Surgical educators should address the science of surgical handicraft in a manner similar to the science of preoperative and postoperative surgical principles that have been espoused over the past 40 years. Although it has been euphemistically said that "you can teach a monkey to operate," few of us have broken the process down into the basic elements to accomplish such a goal. In view of the increasing complexity of operations and equipment, the constraints on animal laboratories and teaching caseloads, and the mounting economic and medico-legal pressures, the development of optimal surgical skills should be a major objective of every surgical training program. By developing novel programs and scientifically evaluating the results of such endeavors, surgical faculties may find increased academic rewards for being a good teacher.

Surgical therapy remains the gold standard treatment for Peyronie's Disease (PD). Surgical options include plication, grafting, and placement of inflatable penile prosthesis (IPP). Postoperative erectile dysfunction (ED) is a potential complication for PD surgery without IPP. We present our large series follow-up to evaluate preoperative risk factors for postoperative ED. The aim of this study is to evaluate preoperative risk factors for the development of ED following surgical correction of PD taking into account the degree of curvature, graft size, surgical approach, hypertension, hyperlipidemia, diabetes, smoking history, preoperative use of phosphodiesterase 5 inhibitors (PDE5), and preoperative duplex ultrasound findings including peak systolic and end diastolic velocities and resistive index. We identified 218 men undergoing either tunica albuginea plication (TAP) or partial plaque excision with pericardial grafting for PD following a previously published algorithm between November 1992 and April 2007. Preoperative and postoperative erectile function, curvature characteristics, presence of vascular risk factors, and duplex ultrasound findings were available on 109 patients. Our primary outcome measure is the development of ED after surgery for PD. Ten percent of TAP and 21% of plaque excision with grafting patients developed postoperative ED. Neither curve direction (P = 0.76), graft area (P = 0.78), surgical approach (P = 0.12), chronic hypertension (P = 0.51), hyperlipidemia (P = 0.87), diabetes (P = 0.69), nor smoking history (P = 0.99) were significant predictors of postoperative ED. No combination of risk factors was found to be predictive of postoperative ED. Preoperative use of PDE5 was not a significant predictor of postoperative ED (P = 0.33). Neither peak systolic, end diastolic, nor resistive index were significant predictors of ED (P = 0.28, 0.28, and 0.25, respectively). This long-term follow-up of a large published series suggests that neither

Observations of surgical teams in the operating room (OR) and interviews with surgeons, circulating registered nurses (RNs), anaesthesiologists and surgical technicians reveal the importance of leadership, team member competencies and an enacted environment that encourages feelings of competence and cooperation. Surgical teams are more loosely coupled than intact and bounded. Team members tend to rely on expected role behaviours to bridge lack of familiarity. While members of the surgical team identified technical competence and preparation as critical factors affecting team performance, they had differing views over the role behaviours of other members of the surgical team that lead to surgical team performance. Observations revealed that the work climate in the OR can shape interpersonal relations and begins to be established when the room is being set up for the surgical case, and evolves as the surgical procedure progresses. The leadership and supervisory competencies of the circulating RNs establish the initial work environment. Both influenced the degree of cooperation and support that was observed, which had an effect on the interactions and relationships between other members of the surgical team. As the surgery unfolds, the surgeon's behaviours and interpersonal relations modify this environment and ultimately influence the degree of team work, team satisfaction and team performance.
The delivery of general paediatric surgery is changing in Ireland. Fewer paediatric surgical procedures are being performed by newly appointed consultant general surgeons, resulting in increased referrals to the specialist paediatric surgeons of uncomplicated general paediatric surgical problems. We surveyed current higher surgical trainees about their views on provision of paediatric surgical services.
Full Text Available This study investigated whether parameters derived from hand motions of expert and novice surgeons accurately and objectively reflect laparoscopic surgical skill levels using an artificial intelligence system consisting of a three-layer chaos neural network. Sixty-seven surgeons (23 experts and 44 novices performed a laparoscopic skill assessment task while their hand motions were recorded using a magnetic tracking sensor. Eight parameters evaluated as measures of skill in a previous study were used as inputs to the neural network. Optimization of the neural network was achieved after seven trials with a training dataset of 38 surgeons, with a correct judgment ratio of 0.99. The neural network that prospectively worked with the remaining 29 surgeons had a correct judgment rate of 79% for distinguishing between expert and novice surgeons. In conclusion, our artificial intelligence system distinguished between expert and novice surgeons among surgeons with unknown skill levels.

The aim of this study was to design a scale for measuring the extent and severity of post-surgical complications in third molar surgery. A multi-stage study using a quantitative methodology and qualitative interview strategy was employed. The degree of importance of signs and symptoms in the evaluation of post-surgical complications was initially observed using a self-report questionnaire administered to maxillofacial surgeons and surgical residents at the International Conference of Oral and Maxillofacial Surgeons in 2011. Then, using exploratory factor analysis, the items and components of the scale were established, with internal consistency determined using Cronbach's alpha. Finally, a group of experts performed a face validity analysis and provided conceptual definitions for the items and components. Thirty-six signs and symptoms were evaluated by 100 respondents, with the most relevant being 'suppuration' and 'abscess'. Factor analysis of the results identified three factors, defined as 'secondary complication', 'soft tissue infection', and 'osseous involvement' (Cronbach's alpha>0.7). Finally, a preliminary scale was designed comprised of these three components and 10 items. In this way, a preliminary scale for measuring post-surgical complications was designed to standardize the semiological concepts of post-surgical assessment. This scale will be assessed in a future investigation. Copyright © 2014 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.
Full Text Available Abstract Background Odontogenic necrotizing fasciitis of the neck is a fulminant infection of odontogenic origin that quickly spreads along the fascial planes and results in necrosis of the affected tissues. It is usually polymicrobial, occurs frequently in immunocompromised patients, and has a high mortality rate. Case presentation A 69-year old Mexican male had a pain in the maxillar right-canine region and a swelling of the submental and submandibular regions. Our examination revealed local pain, tachycardia, hyperthermia (39°C, and the swelling of bilateral submental and submandibular regions, which also were erythematous, hyperthermic, crepitant, and with a positive Godet sign. Mobility and third-degree caries were seen in the right mandibular canine. Bacteriological cultures isolated streptococcus pyogenes and staphylococcus aureus. The histopathological diagnosis was odontogenic necrotizing fasciitis of the submental and submandibular regions. The initial treatment was surgical debridement and the administration of antibiotics. After cultures were negative, the surgical wound was treated with a growth factor-enriched autologous plasma eight times every third day until complete heal
