Esophagus cancer represents a very lethal neoplasm. Esophageal resection is going to be the therapeutic alternative to patients considered surgical candidates. It had been described some esophagus resection procedure. Although, there is not any agreement between surgeon about which are best procedure to patients with esophagus carcinoma. Most of patients who came advanced phase have poor prognostic and only patients, who have illness in early stage, exist expectative to improve survival with lymphadenectomy extended and neoadjuvant. We analyzes retrospectively files of 23 patients submitted to esophagectomy in hospital Solca Quito from 1985 to 2004 with the diagnostic of esophagus carcinoma, considering histology type, location, surgical proceeded, pathologic staging, surgical mortally, mobility and survival time live. Also it makes a review about proceeds of esophagus resection and adjuvant therapy to the esophagus cancer. Conclusions: Esophagectomy transhiatal has limitations in oncological resection and recommend it early lower esophagus lesions and cardiac orifice (dysplasia high grade, T is, TI, NO, MO) in patients of high risk. Right trans thoracic esophagectomy it is considered in all lesions advanced locally lower middle third, and cardias orifice with lymphadenectomy of two areas and have avoid of trans thoracic anastomotic risk. Trans operatively margins upper have been 10 cm and 5 cm distal, always freeze those margins trans operatively. Extended lymphadenectomy to three areas we have no order yet conclusive dates and the chemotherapy neoadjuvant had been a positive impact in the survival in those chemosensitive tumors with appropriate answer and could be totally remove, but randomized testing future could determine his efficacy real.

An increasing number of surgical and nonsurgical procedures are being performed on an ambulatory basis in children. Analysis of a large group of pediatric patients with congenital heart disease undergoing ambulatory procedures has not been undertaken. The objective of this study was to characterize the profile of children with congenital heart disease who underwent noncardiac procedures on an ambulatory basis at our institution, to determine the incidence of adverse cardiovascular and respiratory adverse events, and to determine the risk factors for unscheduled hospital admission. This is a retrospective study of children with congenital heart disease who underwent noncardiac procedures on an ambulatory basis in a single center. Using the electronic preoperative anesthesia evaluation form, we identified 3010 patients with congenital heart disease who underwent noncardiac procedures of which 1028 (34.1%) were scheduled to occur on an ambulatory basis. Demographic, echocardiographic and functional status data, cardiovascular and respiratory adverse events, and reasons for postprocedure admission were recorded. Univariable analysis was conducted. The unplanned hospital admission was 2.7% and univariable analysis demonstrated that performance of an echocardiogram within 6 mo of the procedure and procedures performed in radiology were associated with postoperative admission. Cardiovascular adverse event incidence was 3.9%. Respiratory adverse event incidence was 1.8%. Ambulatory, noncomplex procedures can be performed in pediatric patients with congenital heart disease and good functional status with a relatively low unanticipated hospital admission rate. © 2018 John Wiley & Sons Ltd.

The association between marijuana use and surgical procedures is a matter of increasing societal relevance that has not been well studied in the literature. The primary aim of this study is to evaluate the relationship between marijuana use and in-hospital mortality, as well as to assess associated comorbidities in patients undergoing commonly billed orthopedic surgeries. The National Inpatient Sample (NIS) database from 2010 to 2014 was used to determine the odds ratios for the associations between marijuana use and in-hospital mortality, heart failure (HF), stroke, and cardiac disease (CD) in patients undergoing five common orthopedic procedures: hip (THA), knee (TKA), and shoulder arthroplasty (TSA), spinal fusion, and traumatic femur fracture fixation. Of 9,561,963 patients who underwent one of the five selected procedures in the four-year period, 26,416 (0.28%) were identified with a diagnosis of marijuana use disorder. In hip and knee arthroplasty patients, marijuana use was associated with decreased odds of mortality compared to no marijuana use (pmarijuana use (0.70%), which was associated with decreased odds of mortality (p = 0.0483), HF (p = 0.0076), and CD (p = 0.0003). For spinal fusions, marijuana use was associated with increased odds of stroke (pMarijuana use in patients undergoing shoulder arthroplasty was associated with decreased odds of mortality (pmarijuana use was associated with decreased mortality in patients undergoing THA, TKA, TSA and traumatic femur fixation, although the significance of these findings remains unclear. More research is needed to provide insight into these associations in a growing surgical population.

Full Text Available Aim: In association with increasing life expectancy, the number of elderly individuals undergoing coronary bypass grafting (CABG and additional cardiac surgical procedures are increasing. In this study, we evaluated the effects of additional cardiac procedures and preoperative risk factors for postoperative mortality and morbidity in patients 80 years of age and older. Methods: The records of 29 patients aged 80 years and older (82.86±2.91 who had undergone coronary bypass surgery in the department of cardiac surgery between September 2009 and June 2012, were retrospectively reviewed. The subjects were divided into two groups: group 1 included the patients who had undergone CABG, group 2 consisted of those who had undergone CABG and additional cardiac procedures. Results: The mean age of the patients [14 male (48.3% 15 female (51.7%] was 82.86±2.91 years. The left internal thoracic artery was harvested for all patients. The mean number of graft per patient was 3.07±0.95. Carotid endarterectomy was performed in 3 patients before CABG. CABG and aortic valve replacement were performed in 1 patient. CABG, mitral valve replacement ant tricuspid plasty were performed in another patient. Furthermore, in one patient, abdominal aortic graft replacement due to ruptured abdominal aortic aneurysm and CABG was performed at the same session. The mean EuroSCORE was 5.06±5.16. Postoperative 30 days mortality was 6.8%, and the mean length of stay in hospital was 10.45±8.18 days. Conclusion: Coronary bypass surgery is an acceptable treatment method in patients 80 years of age and older. Although additional cardiac procedures may increase sugical risks, they can be successfully performed. (The Me­di­cal Bul­le­tin of Ha­se­ki 2014; 52: 14-8

Full Text Available INTRODUCTION: There are various procedures available for ptosis correction. Successful outcome not only depends on correct technique but also choosing appropriate procedure for each patient. Selection of procedure is based on available levator function and also other factors like etiology, severity, Bell’s phenomenon etc. If such varied procedure s are performed in a group of patients based on standard criteria and results are evaluated systematically we can determine what works best for a given patient . AIM : Evaluation of outcome of various surgical procedures for upper eyelid ptosis . METHODOLOGY : 25 eyelids of 20 patients who presented to a tertiary centre in south India with complaint of drooping of upper lid were considered. All subjects underwent complete ocular examination corrected visual acuity and detailed ptosis evaluation with particular emphasis on measurement of levator muscle function, MRD1 (margin reflex distance - 1, palpebral fissure width in different gazes and margin crease distance. The effect of various factors like MRD1, MCD, levator function were assessed, the amount of correction required and appropriate surgical procedure was chosen. Surgical procedure of Levator resection, frontalis sling operation, anterior levator aponeurosis advancement, o r other ptosis correction procedures under appropriate anaesthesia were performed. Post - operative evaluation in terms of visual acuity, MRD, Interpalpebral fissure height, lid symmetry, lagophthalmos and complications (if any was done. RESULTS : Levator muscle resection was done in 28% of eyelids, frontal sling surgery in 60% of eyelids, Levator muscle plication in 8% eyelids and levator muscle disinsertion with frontal sling surgery in 4% eyes. Undercorrection was seen in about 44% of eyelids in varying degrees. 56% of the eyes had optimal correction. Symmetric correction was achieved in 76% of eyelids. CONCLUSION: The influence of various preoperative factors on the

Postoperative ileus is a major complication of abdominal surgical procedures To evaluate the incidence of ileus and gastrointestinal morbidity in patients who received immediate postoperative feeding and bowel stimulation after undergoing major gynecologic surgical procedures. During a 5-year period, the authors tracked demographic, surgical outcome, and follow-up information for 707 patients who underwent major gynecologic operations. All patients received the same postoperative orders, including immediate feeding of a diet of choice and bowel stimulation with 30 mL of magnesium hydroxide (milk of magnesia) twice daily until bowel movements occurred. Of 707 patients, 6 (<1%) had postoperative ileus. No patients experienced postoperative bowel obstruction and 2 patients (0.3%) had postoperative intestinal leak. No serious adverse effects associated with bowel stimulation were reported. Immediate postoperative feeding and bowel stimulation is a safe and effective approach to preventing ileus in patients who undergo major gynecologic surgical procedures.

This paper reports on a study in which electrocardiographically gated spin-echo MR imaging was used to evaluate 23 patients with congenital heart disease who had undergone Waterston (n = 3), Potts (n = 2), Senning (n = 3), Fontan (n = 3), Rastelli (n = 4), Damus (n = 1) and Jatene (n = 7) procedures. Surgical shunts, conduits, or baffles were identified correctly in all patients. Patency, atresia and hypoplasia of central pulmonary arteries (PAs) as well as postoperative complications (focal stenosis of PAs, thrombosed pseudoaneurysm, intramural abscess) were diagnosed. MR findings were corroborated with angiography, echocardiography, and surgery. Narrowing of the right ventricular outflow tract and focal compression of the proximal PAs were recognized as specific complications of the Jatene procedure. MR imaging appears to be effective for the postoperative evaluation of surgical procedures used for congenital heart disease

Generally, surgical treatment is recommended for Rockwood type 5 traumatic acromioclavicular joint dislocations. Since 1980, the authors have performed the modified Dewar procedure, the modified Cadenat procedure, and anatomical reconstruction of the coracoclavicular ligaments for this injury. The goal of this study was to determine the ideal surgical procedure for acromioclavicular joint dislocations by comparing these 3 procedures. The modified Dewar procedure was performed on 55 patients (Dewar group), the modified Cadenat procedure was performed on 73 patients (Cadenat group), and anatomical reconstruction of the coracoclavicular ligaments was performed on 11 patients (reconstruction group). According to the UCLA scoring system, therapeutic results averaged 27.3 points in the Dewar group, 28.2 in the Cadenat group, and 28.4 in the reconstruction group. The incidence of residual subluxation or dislocation in the acromioclavicular joint was evaluated at final radiographic follow-up. Subluxation occurred in 21 patients in the Dewar group, 18 in the Cadenat group, and 3 in the reconstruction group. Dislocation occurred in 3 patients in the Dewar group. Osteoarthritic changes in the acromioclavicular joint occurred in 20 patients in the Dewar group, 9 in the Cadenat group, and 1 in the reconstruction group. The modified Cadenat procedure can provide satisfactory therapeutic results and avoid postoperative failure or loss of reduction compared with the modified Dewar procedure. However, the modified Cadenat procedure does not anatomically restore the coracoclavicular ligaments. Anatomic restoration of both coracoclavicular ligaments can best restore acromioclavicular joint function. Copyright 2013, SLACK Incorporated.

Most risk adjustment approaches adjust for patient comorbidities and the primary procedure. However, procedures done at the same time as the index case may increase operative risk and merit inclusion in adjustment models for fair hospital comparisons. Our objectives were to evaluate the impact of surgical complexity on postoperative outcomes and hospital comparisons in gastric cancer surgery. Patients who underwent gastric resection for cancer were identified from a large clinical dataset. Procedure complexity was characterized using secondary procedure CPT codes and work relative value units (RVUs). Regression models were developed to evaluate the association between complexity variables and outcomes. The impact of complexity adjustment on model performance and hospital comparisons was examined. Among 3,467 patients who underwent gastrectomy for adenocarcinoma, 2,171 operations were distal and 1,296 total. A secondary procedure was reported for 33% of distal gastrectomies and 59% of total gastrectomies. Six of 10 secondary procedures were associated with adverse outcomes. For example, patients who underwent a synchronous bowel resection had a higher risk of mortality (odds ratio [OR], 2.14; 95% CI, 1.07-4.29) and reoperation (OR, 2.09; 95% CI, 1.26-3.47). Model performance was slightly better for nearly all outcomes with complexity adjustment (mortality c-statistics: standard model, 0.853; secondary procedure model, 0.858; RVU model, 0.855). Hospital ranking did not change substantially after complexity adjustment. Surgical complexity variables are associated with adverse outcomes in gastrectomy, but complexity adjustment does not affect hospital rankings appreciably. Copyright © 2015 Elsevier Inc.

To determine the usefulness and safety of radiological placement of a central venous catheter by prospectively comparing the results of interventional radiology and blind surgery. For placement of a central venous catheter, the blind surgical method was used in 78 cases (77 patients), and the interventional radiological method in 56 cases (54 patients). The male to female ratio was 66:68, and the patients' mean age was 48 (range, 18-80) years. A tunneled central venous catheter was used in 74 cases, and a chemoport in 60. We evaluated the success and duration of the procedures, the number of punctures required, and ensuing complications, comparing the results of the two methods. The success rates of the interventional radiological and the blind surgical procedure were 100% and 94.8%, respectively. The duration of central catheterization was 3-395 (mean, 120) day, that of chemoport was 160.9 days, and that of tunneled central venous catheter was 95.1 days. The mean number of punctures of the subclavian vein was 1.2 of interventional radiology, and 2.1 for blind surgery. The mean duration of the interventional radiology and the blind surgical procedure was, respectively, 30 and 40 minutes. The postprocedure complication rate was 27.6% (37 cases). Early complications occurred in nine cases (6.7%): where interventional radiology was used, there was one case of hematoma, and blind surgery gave rise to hematoma (n=2), pneumothorax (n=2), and early deviation of the catheter (n=4). Late complications occurred in 32 cases (23.9%). Interventional radiology involved infection (n=4), venous thrombosis (n=1), catheter displacement (n=2) and catheter obstruction (n=5), while the blind surgical procedure gave rise to infection (n=5), venous thrombosis (n=3), catheter displacement (n=4) and catheter obstruction (n=8). The success rate of interventional radiological placement of a central venous catheter was high and the complication rate was low. In comparison with the blind

Most men who request surgical penile enhancement have a normal-sized and fully functional penis but visualize their penises as small (psychological dysmorphism). The aim of this review is to describe the various reported techniques and to provide the available scientific data on the success and complication rates of penile enhancement procedures. We performed an extensive systematic review based on a search of the MEDLINE database for articles published between 1965 and 2008. The following key words were used: penis, enhancement, enlargement, phalloplasty, reconstruction, girth, lengthening, and augmentation. Only English-language articles that were related to penile surgery and dysmorphobia were sought. We excluded articles in which fewer than five cases were described and articles in which the type of surgical treatment and the outcome were not clear. Of the 176 papers found, 34 were selected and critically analyzed. We found only a small number of well-designed and comprehensive studies, and most of the published articles reported data that were obtained from small cohorts of patients. The more recently published studies presented better methodologies and descriptions of the surgical techniques than did the older publications. In general, penile enhancement surgery can cause a 1-2-cm increase in penile length and a 2.5-cm augmentation of penile girth. Unwanted outcomes and complications, namely penile deformity, paradoxical penile shortening, disagreeable scarring, granuloma formation, migration of injected material, and sexual dysfunction were reported frequently in these studies. Disappointing short- and long-term patient satisfaction rates following these procedures were also reported in most studies. To date, the use of cosmetic surgery to enlarge the penis remains highly controversial. There is a lack of any standardization of all described procedures. Indications and outcome measures are poorly defined, and the reported complications are unacceptably high

The exposure of a medical team to radiation during surgical procedures evidently depends on the duration and difficulties of the particular procedure. We have made a dosimetric study of the average equivalent doses received by the surgical teams during 10 different surgical procedures over a period of one month. Our results demonstrate that the levels of ionizing radiation that the members of the teams receive typically do not surpass the limits stipulated for the following surgical procedures: nefrolithotomy, percutaneous ureterolithomy, ureteroscoy connected with removal of stones in the inferior third of the ureter, osteosynthesis of the tibial plateau together with a articular toalet and minireconstruction of the knee. For compound surgical procedures, for example, osteosynthesis of a femur fracture together with biopsy of an exposed femur or percutaneous nefrolithotomy (complex cases), the dose limits have been surpassed owing to the additional fluoroscopy needed in those p rocedures.

The fidelity of image-guided neurosurgical procedures is often compromised due to the mechanical deformations that occur during surgery. In recent work, a framework was developed to predict the extent of this brain shift in brain-tumor resection procedures. The approach uses preoperatively determined surgical variables to predict brain shift and then subsequently corrects the patient's preoperative image volume to more closely match the intraoperative state of the patient's brain. However, a clinical workflow difficulty with the execution of this framework is the preoperative acquisition of surgical variables. To simplify and expedite this process, an Android, Java-based application was developed for tablets to provide neurosurgeons with the ability to manipulate three-dimensional models of the patient's neuroanatomy and determine an expected head orientation, craniotomy size and location, and trajectory to be taken into the tumor. These variables can then be exported for use as inputs to the biomechanical model associated with the correction framework. A multisurgeon, multicase mock trial was conducted to compare the accuracy of the virtual plan to that of a mock physical surgery. It was concluded that the Android application was an accurate, efficient, and timely method for planning surgical variables.

Full Text Available A series of surgical interventions - relaxing corneal incisions, intraocular lens, and intrastromal rings - were used to correct a case of extreme ametropia in a thin cornea after a penetrating keratoplasty in an 18-year-old patient who presented with a -10.25 -8.50 × 120 preoperative refraction and 20/200 best-corrected visual acuity (BCVA. After a series of surgical procedures, the patient's BCVA in his left eye improved to 20/30 with +0.50 -1.00 × 170, the slit lamp examination showed no significant findings, and the patient's visual complaints disappeared. At the 1-year follow-up, the BCVA was 20/25, without visual complaints. The process of individualizing the surgical procedure in the present case was employed in an outcome-based approach, that is, the next surgical procedure was defined after the surgery and postoperative evaluation. The patient did not present complications during the follow-up period of 2.5 years.

Post-surgical infections (PSIs) are a source of preventable perioperative morbidity. No guidelines exist for the use of perioperative antibiotics in pediatric urologic procedures. This study reports the rate of PSIs in non-endoscopic pediatric genitourinary procedures at our institution. Secondary aims evaluate the association of PSI with other perioperative variables, including wound class (WC) and perioperative antibiotic administration. Data from consecutive non-endoscopic pediatric urologic procedures performed between August 2011 and April 2014 were examined retrospectively. The primary outcome was the rate of PSIs. PSIs were classified as superficial skin (SS) and deep/organ site (D/OS) according to Centers for Disease Control and Prevention guidelines, and urinary tract infection (UTI). PSIs were further stratified by WC1 and WC2 and perioperative antibiotic usage. A relative risk and chi-square analysis compared PSI rates between WC1 and WC2 procedures. A total of 1185 unique patients with 1384 surgical sites were reviewed; 1192 surgical sites had follow-up for inclusion into the study. Ten total PSIs were identified, for an overall infection rate of 0.83%. Of these, six were SS, one was D/OS, and three were UTIs. The PSI rate for WC1 (885 sites) and WC2 (307 sites) procedures was 0.34% and 2.28%, respectively, p antibiotics (0.35% vs. 0.33%). All WC2 procedures received antibiotics. Post-surgical infections are associated with significant perioperative morbidity. In some studies, PSI can double hospital costs, and contribute to hospital length of stay, admission to intensive care units, and impact patient mortality. Our study demonstrates that the rate of PSI in WC1 operations is low, irrespective of whether the patient received perioperative antibiotics (0.35%) or no antibiotics (0.33%). WC2 operations were the larger source of morbidity with an infection rate of 2.28% and a 6.7 fold higher increase in relative risk. WC1 procedures have a rate of

Variability in surgical procedure times increases the cost of healthcare delivery by increasing both the underutilization and overutilization of expensive surgical resources. To reduce variability in surgical procedure times, we must identify and study its sources. Our data set consisted of all surgeries performed over a 7-yr period at a large teaching hospital, resulting in 46,322 surgical cases. To study factors associated with variability in surgical procedure times, data mining techniques were used to segment and focus the data so that the analyses would be both technically and intellectually feasible. The data were subdivided into 40 representative segments of manageable size and variability based on headers adopted from the common procedural terminology classification. Each data segment was then analyzed using a main-effects linear model to identify and quantify specific sources of variability in surgical procedure times. The single most important source of variability in surgical procedure times was surgeon effect. Type of anesthesia, age, gender, and American Society of Anesthesiologists risk class were additional sources of variability. Intrinsic case-specific variability, unexplained by any of the preceding factors, was found to be highest for shorter surgeries relative to longer procedures. Variability in procedure times among surgeons was a multiplicative function (proportionate to time) of surgical time and total procedure time, such that as procedure times increased, variability in surgeons' surgical time increased proportionately. Surgeon-specific variability should be considered when building scheduling heuristics for longer surgeries. Results concerning variability in surgical procedure times due to factors such as type of anesthesia, age, gender, and American Society of Anesthesiologists risk class may be extrapolated to scheduling in other institutions, although specifics on individual surgeons may not. This research identifies factors associated

To analyze the management of postoperative pain after complex ophthalmic surgery and to compare it to the guidelines. A retrospective study. University Hospital Split, Croatia. Patients (N = 447) who underwent complex ophthalmic surgical procedures from 2008 to 2012. The following data were extracted from patient medical records: age, gender, type and dosage of premedication, preoperative patient's physical status, type of procedure, duration of procedure-surgical and anesthesia time, type and dosage of anesthesia, the type and dosage of postoperative analgesia for each postoperative day. None of the patients had information about pain intensity in their records. There were 90% patients who did not receive any medication the night before surgery, 54% did not receive any premedication immediately before surgery, 19% did not receive any pain medication after the surgery in the operating room and 46% of patients did not receive any analgesics after being released to the ophthalmology department. Among those who received analgesia after surgery, 98% received only one dose of an analgesic, and 93% of patients received analgesia only on the day of the surgery. Furthermore, patients were returned to the department immediately after surgery, without intensive monitoring. During the analyzed five years there were no educational session organized by anesthesiologist to the ophthalmic surgeons. Postoperative pain management and perioperative care of patients undergoing major ophthalmic surgery indicates lack of attention towards pain intensity and postoperative analgesia. Appropriate interventions should be employed to improve postoperative pain management, to facilitate patient recovery. Wiley Periodicals, Inc.

Patient satisfaction and quality of surgical care in US hospitals.

The relationship between patient satisfaction and surgical quality is unclear for US hospitals. Using national data, we examined if hospitals with high patient satisfaction have lower levels of performance on accepted measures of the quality and efficiency of surgical care. Federal policymakers have made patient satisfaction a core measure for the way hospitals are evaluated and paid through the value-based purchasing program. There is broad concern that performance on patient satisfaction may have little or even a negative correlation with the quality of surgical care, leading to potential trade-offs in efforts to improve patient experience with other surgical quality measures. We used the Hospital Consumer Assessment of Healthcare Providers and Systems survey data from 2010 and 2011 to assess performance on patient experience. We used national Medicare data on 6 common surgical procedures to calculate measures of surgical efficiency and quality: risk-adjusted length of stay, process score, risk-adjusted mortality rate, risk-adjusted readmission rate, and a composite z score across all 4 metrics. Multivariate models adjusting for hospital characteristics were used to assess the independent relationships between patient satisfaction and measures of surgical efficiency and quality. Of the 2953 US hospitals that perform one of these 6 procedures, the median patient satisfaction score was 69.5% (interquartile range, 63%-75.5%). Length of stay was shorter in hospitals with the highest levels of patient satisfaction (7.1 days vs 7.7 days, P patient satisfaction had the higher process of care performance (96.5 vs 95.5, P patient satisfaction also had a higher composite score for quality across all measures (P patient satisfaction provided more efficient care and were associated with higher surgical quality. Our findings suggest there need not be a trade-off between good quality of care for surgical patients and ensuring a positive patient experience.

In many surgeries, especially orthopedic procedures, power tools such as saws and drills are used. These tools may produce aerosolized blood and other biological material from bone and soft tissues. Surgical lasers and electrocautery tools can also produce aerosols when tissues are vaporized and condensed. Studies have been reported in the literature concerning production of aerosols during surgery, and some of these aerosols may contain infectious material. Garden et al. (1988) reported the presence of papilloma virus DNA in the fumes produced from laser surgery, but the infectivity of the aerosol was not assessed. Moon and Nininger (1989) measured the size distribution and production rate of emissions from laser surgery and found that particles were generally less than 0.5 {mu}m diameter. More recently there has been concern expressed over the production of aerosolized blood during surgical procedures that require power tools. In an in vitro study, the production of an aerosol containing the human immunodeficiency virus (HIV) was reported when power tools were used to cut tissues with blood infected with HIV. Another study measured the size distribution of blood aerosols produced by surgical power tools and found blood-containing particles in a number of size ranges. Health care workers are anxious and concerned about whether surgically produced aerosols are inspirable and can contain viable pathogens such as HIV. Other pathogens such as hepatitis B virus (HBV) are also of concern. The Occupational Safety and Health funded a project at the National Institute for Inhalation Toxicology Research Institute to assess the extent of aerosolization of blood and other tissues during surgical procedures. This document reports details of the experimental and sampling approach, methods, analyses, and results on potential production of blood-associated aerosols from surgical procedures in the laboratory and in the hospital surgical suite.

Full Text Available AIM To compare the changes in blood glucose level associated with administration of adrenaline containing local anesthetic in diabetic and non-diabetic patients undergoing minor oral surgical procedures. METHODS AND MATERIAL The study included 150 well controlled diabetic patients and 150 non-diabetic healthy patients in age group of 40-60 years who underwent minor oral surgical procedures (trans alveolar extractions, alveoplasty and flap surgeries. Patients in both the group were administered 1.8ml of local anesthetic agent containing 1:100,000 adrenaline for inferior alveolar nerve block and 0.2 ml of anesthetic agent for long buccal nerve block. Blood glucose levels were assessed and compared during pre-operative and one hour post-operative period. STATISTICAL ANALYSIS The comparison of the random blood sugar levels preop and postop in both the groups were compared using paired t test and RBS levels between two groups were analysed using unpaired t test. P value less than 0.05 was considered statistically significant. RESULTS No statistically significant change in post-operative blood glucose level was noted between the diabetic and non-diabetic patients. CONCLUSION The study concluded that it is safe to administer local anesthetic containing 1:100,000 adrenaline in smaller volumes to well controlled diabetic patients.

Full Text Available Context: Periodontal surgical procedures produce varying degree of stress in all patients. Nitrous oxide-oxygen inhalation sedation is very effective for adult patients with mild-to-moderate anxiety due to dental procedures and needle phobia. Aim: The present study was designed to perform periodontal surgical procedures under nitrous oxide-oxygen inhalation sedation and assess whether this technique actually reduces stress physiologically, in comparison to local anesthesia alone (LA during lengthy periodontal surgical procedures. Settings and Design: This was a randomized, split-mouth, cross-over study. Materials and Methods: A total of 16 patients were selected for this randomized, split-mouth, cross-over study. One surgical session (SS was performed under local anesthesia aided by nitrous oxide-oxygen inhalation sedation, and the other SS was performed on the contralateral quadrant under LA. For each session, blood samples to measure and evaluate serum cortisol levels were obtained, and vital parameters including blood pressure, heart rate, respiratory rate, and arterial blood oxygen saturation were monitored before, during, and after periodontal surgical procedures. Statistical Analysis Used: Paired t-test and repeated measure ANOVA. Results: The findings of the present study revealed a statistically significant decrease in serum cortisol levels, blood pressure and pulse rate and a statistically significant increase in respiratory rate and arterial blood oxygen saturation during periodontal surgical procedures under nitrous oxide inhalation sedation. Conclusion: Nitrous oxide-oxygen inhalation sedation for periodontal surgical procedures is capable of reducing stress physiologically, in comparison to LA during lengthy periodontal surgical procedures.

Total laryngectomy is a standard procedure in head-and-neck surgery for the treatment of cancer patients. Recent clinical experiences have indicated a clinical benefit for patients undergoing transoral robot-assisted total laryngectomy (TORS-TL) with commercially available systems. Here, a new hybrid procedure for total laryngectomy is presented. TORS-TL was performed in human cadavers (n = 3) using a transoral-transcervical hybrid procedure. The transoral approach was performed with a robotic flexible robot-assisted surgical system (Flex®) and compatible flexible instruments. Transoral access and visualization of anatomical landmarks were studied in detail. Total laryngectomy is feasible with a combined transoral-transcervical approach using the flexible robot-assisted surgical system. Transoral visualization of all anatomical structures is sufficient. The flexible design of the robot is advantageous for transoral surgery of the laryngeal structures. Transoral robot assisted surgery has the potential to reduce morbidity, hospital time and fistula rates in a selected group of patients. Initial clinical studies and further development of supplemental tools are in progress. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

To compare multimedia and standard consent, in respect to patient comprehension, anxiety, and satisfaction, for various surgical/interventional procedures. Electronic searches of PubMed, MEDLINE, Ovid, Embase, and Google Scholar were performed. Relevant articles were assessed by 2 independent reviewers. Comparative (randomized and nonrandomized control trials) studies of multimedia and standard consent for a variety of surgical/interventional procedures were included. Studies had to report on at least one of the outcome measures. Studies were reviewed by 2 independent investigators. The first investigator extracted all relevant data, and consensus of each extraction was performed by a second investigator to verify the data. Overall, this review suggests that the use of multimedia as an adjunct to conventional consent appears to improve patient comprehension. Multimedia leads to high patient satisfaction in terms of feasibility, ease of use, and availability of information. There is no conclusive evidence demonstrating a significant reduction in preoperative anxiety.

Without treatment, the life expectancy of patients with Marfan syndrome is reduced by the associated cardiovascular abnormalities. In this study, we reviewed our experience of the patients with Marfan syndrome who required multiple surgical interventions to identify the optimal treatment for these patients. Between January 1986 and December 2000, 44 patients with Marfan syndrome were operated on at Shizuoka City Hospital (SCH). Among them, 10 patients (22.7%) underwent multiple surgical interventions. There were 5 male and 5 female patients with a mean age of 40.6 +/- 16.1 years at the initial surgery. Only one patient was operated on at another hospital for his first, second, and third operations. His fourth operation was carried out at SCH. The remaining 9 patients underwent a total of 14 additional surgical procedures at SCH. Computed tomography (CT) scans were taken every 6 months postoperatively, and aortic diameter greater than 60 mm was considered as the indication for the additional surgery. There were no early death and one late death. The causes of additional surgery were enlargement of true aneurysm in 6, enlargement of residual dissection in 4, new dissection in 4, false aneurysm at the coronary anastomosis of Bentall procedure in 1. In 9 patients, both ascending and descending aorta were replaced. Among these 9 patients, only 3 patients underwent total arch replacement, and remaining 6 patients had their arch left in place with or without dissection. Our current strategy of the treatment of Marfan patients with acute type A dissection is total arch replacement with an elephant trunk at the initial emergent surgery.

Surgical treatment of chronic pancreatitis is indicated for intractable pain. Frey's procedure is an accepted treatment for this disease. The aim of the present study was to describe a single-centre experience in the treatment of chronic pancreatitis using Frey's procedure. A retrospective analysis of 73 patients who underwent a Frey's procedure between 1991 to 2007 and had at least 1 year of follow-up. Demographics, indication for surgery, peri-operative complications and late outcomes were analysed. The median age was 39.9 years. Seventy out of the 73 (95.8%) patients were male. The median pre-operative body mass index (BMI) was 19.1 kg/m(2). All patients had abdominal pain, 34 (46.6%) of them daily and 13 (17.8%) weekly, with moderate or severe intensity in 98.6% (n= 72). The aetiology was secondary to alcohol in 70 patients (95.9%), with a median consumption of 278 g per day. The surgical morbidity rate was 28.7%; there were no deaths. Median post-operative follow-up was 77.0 months; 64 patients (91.4%) had complete pain relief and post-operative BMI was 22.4 kg/m(2) (P<0.001). All patients with pre-operative endocrine and exocrine insufficiencies showed no reversal of the situation. New onset insufficiencies appeared late. Frey's procedure was a safe and effective therapeutic option for the surgical treatment of patients with intractable pain caused by chronic pancreatitis. © 2011 International Hepato-Pancreato-Biliary Association.

Economic downturn can have a wide range of effects on medicine at both individual and national levels. We aim to describe these effects in relation to surgical volume to guide future planning for physician specialization, patient expectations in the face of economic crises, or estimating healthcare expenditure. We hypothesized that because of high out-of-pocket costs, cosmetic procedure volumes would be most affected by economic decline. A systematic review was conducted using MEDLINE, Embase, and ABI/INFORMS. The main search terms were "economic recession" and "surgical procedures, operative". Studies were included if surgical volumes were measured and economic indicators were used as predictors of economic conditions. Twelve studies were included, and the most common subject was cosmetic (n = 5), followed by orthopedic (n = 2) and cardiac surgeries (n = 2). The majority of studies found that in periods of economic downturn, surgical volume decreased. Among the eight studies using Pearson's correlation analysis, there were no significant differences between cosmetic procedures and other elective procedures, indicating that cosmetic procedures may display trends similar to those of non-cosmetic elective procedures in periods of economic downturn. Surgical volume generally decreased when economic indicators declined, observed for both elective and non-elective surgery fields. However, a few specific procedure volumes such as vasectomy and caesarean section for male babies increased during the economic downturn. Knowledge of these trends can be useful for future surgical planning and distribution of healthcare resources. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

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.

To assess retinal complications and to identify risk factors for retinal complications following aqueous shunt procedures. Records of 38 consecutive aqueous shunt procedures that were performed on 36 patients at the Eye Institute of the Medical College of Wisconsin, Milwaukee, from June 1993 to March 1995 (minimum follow-up, 6 months) were reviewed. The mean +/- SD follow-up was 11.4 +/- 5.2 months (median, 10.5 months). Twelve patients (32%) had the following retinal complications: 4 serous choroidal effusions (10%) that required drainage, 3 suprachoroidal hemorrhages (8%), 2 vitreous hemorrhages (5%), 1 rhegmatogenous retinal detachment (3%), 1 endophthalmitis (3%), and 1 scleral buckling extrusion (3%). Surgical procedures for retinal complications were required in 8 (67%) of these 12 patients. Visual acuity decreased 2 lines or more in 9 (75%) of these 12 patients. The median onset of a postoperative retinal complication was 12.5 days, with 10 patients (83%) experiencing complications within 35 days. Serous choroidal effusions developed in 10 other patients (26%), and these effusions resolved spontaneously. Visual acuity decreased 2 lines or more in 2 (20%) of these additional 10 patients. Patients who experienced serious retinal complications were significantly older, had a higher rate of hypertension, and postoperative ocular hypotony. Serious retinal complications were distributed evenly among patients with Krupin valves with discs and Molteno and Baerveldt devices. Experience with the Ahmed glaucoma valve implant was limited. Aqueous shunt procedures may be associated with significant retinal complications and subsequent visual loss.

Procedure times are important variables that often are included in studies of quality and efficiency. However, due to the need for costly chart review, most studies are limited to single-institution analyses. In this article, the authors describe how well the anesthesia claim from Medicare can estimate chart times. The authors abstracted information on time of induction and entrance to the recovery room ("anesthesia chart time") from the charts of 1,931 patients who underwent general and orthopedic surgical procedures in Pennsylvania. The authors then merged the associated bills from claims data supplied from Medicare (Part B data) that included a variable denoting the time in minutes for the anesthesia service. The authors also investigated the time from incision to closure ("surgical chart time") on a subset of 1,888 patients. Anesthesia claim time from Medicare was highly predictive of anesthesia chart time (Kendall's rank correlation tau = 0.85, P < 0.0001, median absolute error = 5.1 min) but somewhat less predictive of surgical chart time (Kendall's tau = 0.73, P < 0.0001, median absolute error = 13.8 min). When predicting chart time from Medicare bills, variables reflecting procedure type, comorbidities, and hospital type did not significantly improve the prediction, suggesting that errors in predicting the chart time from the anesthesia bill time are not related to these factors; however, the individual hospital did have some influence on these estimates. Anesthesia chart time can be well estimated using Medicare claims, thereby facilitating studies with vastly larger sample sizes and much lower costs of data collection.

With a growing sphere of influence in the modern world, online social media serves as a readily accessible interface for communication of information. Aesthetic medicine is one of many industries increasingly influenced by social media, as evidenced by the popular website, "RealSelf," an online community founded in 2006 that compiles ratings, reviews, photographs, and expert physician commentary for nearly 300 cosmetic treatments. To investigate the current preferences of patients regarding cosmetic non-surgical, surgical, and dental treatments on RealSelf and in the documented medical literature. On a single day of data collection, all cosmetic treatments or procedures reviewed on the RealSelf website were tabulated, including name, percent "worth it" rating, total number of reviews, and average cost. Patient satisfaction rates documented in the current medical literature for each cosmetic treatment or procedure were also recorded. Statistical t-testingcomparing RealSelf ratings and satisfaction rates in the literature was performed for each category-non-surgical, surgical, and dental. The top ten most-commonly reviewed non-surgical treatments, top ten most-commonly reviewed surgical procedures, and top 5 most-commonly reviewed dental treatments, along with documented satisfaction rates in the medical literature for each treatment or procedure were recorded in table format and ranked by RealSelf "worth it" rating. Paired t-testing revealed that satisfaction rates documented in the literature were significantly higher than RealSelf "worth it" ratings for both non-surgical cosmetic treatments (p=0.00076) and surgical cosmetic procedures (p=0.00056), with no statistically significant difference for dental treatments. For prospective patients interested in cosmetic treatments or procedures, social media sites such as RealSelf may offer information helpful to decision-making as well enable cosmetic treatment providers to build reputations and expand practices.

Full Text Available Introduction: Preservation of the health of periodontium is very important for the long-term success of restored teeth and a balance should always be created between the patients’ esthetic requirements and the periodontal health. Failures of crown lengthening procedures are classified into early and late failures. The aim of this study was to evaluate the prevalence of early failures of crown leathering surgical procedures. Materials and methods: In this descriptive/cross-sectional study, 96 patients were selected from those referring to the Department of Periodontitis, Tabriz Faculty of Dentistry, who required crown lengthening procedures. The particulars of these patients were recorded in special forms and the reasons for the failure of surgical procedures were separately determined at 2- and 6-week intervals. In addition, the frequencies of the reasons for failures were determined in percentages and absolute frequencies. Data were analyzed with descriptive statistics (frequencies and percentages using SPSS 21. Statistical significance was set at P<0.05. Results: Evaluation of patients 6 weeks after surgery showed a failure rate of 14.5% for crown lengthening procedures in patients referring to the Department of Periodontics, Tabriz Faculty of Dentistry. The most common reasons for such early failures in the 6th week, in descending order, were a lack of sufficient keratinized gingiva around in tooth in question, fracture of the tooth structure after surgery, inadequate surgery (not creating a proper distance between the healthy margin and the crest and the coronal returning of the gingival tissue on the tooth. A lack of sufficient keratinized gingiva around the tooth was the most frequent reason for the early failure of crown lengthening procedure at both study intervals. Conclusion: It can be concluded from the results of the present study that during the 6th postoperative week the crown lengthening procedures exhibited a 14.5% failure rate

To develop baseline data in relation to paediatric minor oral surgical procedures undertaken with both general anaesthesia and nitrous oxide inhalation sedation within a Hospital Dental Service. Data were collected prospectively over a three-year period from May 2003 to June 2006 for patients attending the Departments of Paediatric Dentistry, Dundee Dental Hospital and Ninewells Hospital, NHS Tayside, Great Britain, for all surgical procedures undertaken with either inhalation sedation or general anaesthetic. Both operator status and the procedure being undertaken were noted. In addition, the operating time was recorded. Data for 166 patients (F: 102; M: 64) with a median age of 12.50 (inter-quartile range 10.00, 14.20) years showed that 195 surgical procedures were undertaken. Of these 160 and 35 were with general anaesthetic and sedation respectively. The surgical removal of impacted, carious and supernumerary unit(s) accounted for 53.8% of all procedures, whilst the exposure of impacted teeth and soft tissue surgery represented 34.9% and 11.3% of procedures respectively. The median surgical time for techniques undertaken with sedation was 30.00 (inter-quartile range 25.00, 43.50) minutes whilst that for general anaesthetic was similar at 30.00 (inter-quartile range 15.25, 40.00) minutes (not statistically significant, (Mann Whitney U, W = 3081.5, P = 0.331). The majority of paediatric minor oral surgical procedures entail surgical exposure or removal of impacted teeth. The median treatment time for most procedures undertaken with either general anaesthetic or nitrous oxide sedation was 30 minutes.

Multimodal Analgesia in Breast Surgical Procedures: Technical and Pharmacological Considerations for Liposomal Bupivacaine Use

Directory of Open Access Journals (Sweden)

Anoushka M. Afonso, MD

2017-09-01

Full Text Available Enhanced recovery after surgery is a multidisciplinary perioperative clinical pathway that uses evidence-based interventions to improve the patient experience as well as increase satisfaction, reduce costs, mitigate the surgical stress response, accelerate functional recovery, and decrease perioperative complications. One of the most important elements of enhanced recovery pathways is multimodal pain management. Herein, aspects relating to multimodal analgesia following breast surgical procedures are discussed with the understanding that treatment decisions should be individualized and guided by sound clinical judgment. A review of liposomal bupivacaine, a prolonged-release formulation of bupivacaine, in the management of postoperative pain following breast surgical procedures is presented, and technical guidance regarding optimal administration of liposomal bupivacaine is provided.

Transferring unstable, ill neonates to and from the operating rooms carries significant risks and can lead to morbidity. We report on our experience in performing certain procedures in critically ill neonates in the neonatal intensive care unit (NICU). We examined the feasibility and safety for such an approach. All surgical procedures performed in the NICU between January 1999 and December 2005 were analyzed in terms of demographic data, diagnosis, preoperative stability of the patient, procedures performed, complications and outcome. Operations were performed at beside in the NICU in critically ill, unstable neonates who needed emergency surgery, in neonates of low birth weight (<1000 gm) and in neonates on special equipments like higher frequency ventilators and nitrous oxide. Thirty-seven surgical procedures were performed including 12 laparotomies, bowel resection and stomies, 7 repairs of congenital diaphragmatic hernias, 4 ligations of patent ductus arteriosus and various others. Birth weights ranged between 850 gm and 3500 gm (mean 2000 gm). Gestational age ranged between 25 to 42 weeks (mean, 33 weeks). Age at surgery was between 1 to 30 days (mean, 30 days). Preoperatively, 19 patients (51.3%) were on inotropic support and all were intubated and mechanically ventilated. There was no mortality related to surgical procedures. Postoperatively, one patient developed wound infection and disruption. Performing major surgical procedures in the NICU is both feasible and safe. It is useful in very low birth weight, critically ill neonates who have definite risk attached to transfer to the operating room. No special area is needed in the NICU to perform complication-free surgery, but designing an operating room within the NICU will be ideal. (author)

Are minimally invasive procedures harder to acquire than conventional surgical procedures?

Hiemstra, Ellen; Kolkman, Wendela; le Cessie, Saskia; Jansen, Frank Willem

2011-01-01

It is frequently suggested that minimally invasive surgery (MIS) is harder to acquire than conventional surgery. To test this hypothesis, residents' learning curves of both surgical skills are compared. Residents had to be assessed using a general global rating scale of the OSATS (Objective Structured Assessment of Technical Skills) for every procedure they performed as primary surgeon during a 3-month clinical rotation in gynecological surgery. Nine postgraduate-year-4 residents collected a total of 319 OSATS during the 2 years and 3 months investigation period. These assessments concerned 129 MIS (laparoscopic and hysteroscopic) and 190 conventional (open abdominal and vaginal) procedures. Learning curves (in this study defined as OSATS score plotted against procedure-specific caseload) for MIS and conventional surgery were compared using a linear mixed model. The MIS curve revealed to be steeper than the conventional curve (1.77 vs. 0.75 OSATS points per assessed procedure; 95% CI 1.19-2.35 vs. 0.15-1.35, p < 0.01). Basic MIS procedures do not seem harder to acquire during residency than conventional surgical procedures. This may have resulted from the incorporation of structured MIS training programs in residency. Hopefully, this will lead to a more successful implementation of the advanced MIS procedures.

Full Text Available Background: Surgical care is an essential component of health care of children worldwide. Incidences of congenital anomalies, trauma, cancers and acquired diseases continue to rise and along with that the impact of surgical intervention on public health system also increases. It then becomes essential that the surgical teams make the procedures safe and error proof. The World Health Organization (WHO has instituted the surgical checklist as a global initiative to improve surgical safety. Aims: To assess the acceptance, application and adherence to the WHO Safe Surgery Checklist in Pediatric Surgery Practice at a university teaching hospital. Materials and Methods: In a prospective study, spanning 2 years, the checklist was implemented for all patients who underwent operative procedures under general anesthesia. The checklist identified three phases of an operation, each corresponding to a specific period in the normal flow of work: Before the induction of anesthesia ("sign in", before the skin incision ("time out" and before the patient leaves the operating room ("sign out". In each phase, an anesthesiologist,-"checklist coordinator," confirmed that the anesthesia, surgery and nursing teams have completed the listed tasks before proceeding with the operation and exit. The checklist was used for 3000 consecutive patients. Results: No major perioperative errors were noted. In 54 (1.8% patients, children had the same names and identical surgical procedure posted on the same operation list. The patient identification tag was missing in four (0.1% patients. Mention of the side of procedures was missing in 108 (3.6% cases. In 0.1% (3 of patients there was mix up of the mention of side of operation in the case papers and consent forms. In 78 (2.6% patients, the consent form was not signed by parents/guardians or the side of the procedure was not quoted. Antibiotic orders were missing in five (0.2% patients. In 12 (0.4% cases, immobilization of the

Most patient education involves passive learning. To improve patient education regarding surgery, an active learning workshop-based teaching method is proposed. The objective of this study was to assess level of patient surgical knowledge, achievement of workshop learning objectives, patient apprehension about future surgery, and participant workshop satisfaction after completing a surgical training workshop. A four-station workshop (surgical scrub, surgical suture, laparoscopic surgery, and robotic surgery) was developed to teach four important components of the surgical process. Healthy, surgery-naive adolescents were enrolled to attend this 1-h workshop-based training program. Training received by participants was technically and procedurally identical to training received by actual surgeons. Pre- and post-workshop questionnaires were used to assess learning outcomes. There were 1312 participants, with a mean age 15.9 ± 1.1 years and a gender breakdown of 303 males and 1009 females. For surgical knowledge, mean pre-workshop and post-workshop scores were 6.1 ± 1.5 and 7.5 ± 1.5 (out of 10 points), respectively (p education is an effective way to improve understanding of surgery-related processes. This teaching method may also decrease apprehension that patients or potential patients harbor regarding a future surgical procedure.

ProSeal laryngeal mask airway: An alternative to endotracheal intubation in paediatric patients for short duration surgical procedures

Full Text Available The laryngeal mask airway (LMA is a supraglottic airway management device. The LMA is preferred for airway management in paediatric patients for short duration surgical procedures. The recently introduced ProSeal (PLMA, a modification of Classic LMA, has a gastric drainage tube placed lateral to main airway tube which allows the regurgitated gastric contents to bypass the glottis and prevents the pulmonary aspiration. This study was done to compare the efficacy of ProSeal LMA with an endotracheal tube in paediatric patients with respect to number of attempts for placement of devices, haemodynamic responses and perioperative respiratory complications. Sixty children, ASA I and II, weighing 10-20 kg between 2 and 8 years of age group of either sex undergoing elective ophthalmological and lower abdominal surgeries of 30-60 min duration, randomly divided into two groups of 30 patients each were studied. The number of attempts for endotracheal intubation was less than the placement of PLMA. Haemodynamic responses were significantly higher (P<0.05 after endotracheal intubation as compared to the placement of PLMA. There were no significant differences in mean SpO 2 (% and EtCO 2 levels recorded at different time intervals between the two groups. The incidence of post-operative respiratory complications cough and bronchospasm was higher after extubation than after removal of PLMA. The incidence of soft tissue trauma was noted to be higher for PLMA after its removal. There were no incidences of aspiration and hoarseness/sore throat in either group. It is concluded that ProSeal LMA can be safely considered as a suitable and effective alternative to endotracheal intubation in paediatric patients for short duration surgical procedures.

In many types of surgery, especially orthopedic procedures, power tools such as saws and drills are used. These tools can impart considerable energy in disrupting tissue and may produce aerosolized blood and material from bone and other tissues. Surgical lasers and electrocautery tools can also produce aerosols due to vaporization of blood and tissues. A number of studies have been reported concerning production of aerosols during surgery, and some of the aerosols produced may contain infectious materials. Health care workers have expressed concern and questions pertaining to the occupational transmission of blood-borne pathogens including the human immunodeficiency virus (HIV) and hepatitis B virus (HBV) via blood aerosols during surgery. Little or no data existed characterizing the aerosols produced performing surgical procedures. Because of this lack of data, the National Institute for Occupational Safety and Health funded a project at ITRI to assess the extent of aerosolization of blood and other tissues during surgical procedures in the laboratory and in a hospital surgical suite.

Full Text Available In rural India most of the surgical patients become impoverished due to surgical treatment pushing several families below poverty line. We describe the various methods that we tried to help these patients pay for the surgical procedures without becoming impoverished. Some of them were successful and many of them were not so successful. The large turnover and innovative methods helped the mission hospitals to serve the poor and the marginalized. Some of these methods might not be relevant in areas other than Northeast India while many could be used in other areas.

Image-guidance for surgical procedures

International Nuclear Information System (INIS)

Peters, Terry M

2006-01-01

Contemporary imaging modalities can now provide the surgeon with high quality three- and four-dimensional images depicting not only normal anatomy and pathology, but also vascularity and function. A key component of image-guided surgery (IGS) is the ability to register multi-modal pre-operative images to each other and to the patient. The other important component of IGS is the ability to track instruments in real time during the procedure and to display them as part of a realistic model of the operative volume. Stereoscopic, virtual- and augmented-reality techniques have been implemented to enhance the visualization and guidance process. For the most part, IGS relies on the assumption that the pre-operatively acquired images used to guide the surgery accurately represent the morphology of the tissue during the procedure. This assumption may not necessarily be valid, and so intra-operative real-time imaging using interventional MRI, ultrasound, video and electrophysiological recordings are often employed to ameliorate this situation. Although IGS is now in extensive routine clinical use in neurosurgery and is gaining ground in other surgical disciplines, there remain many drawbacks that must be overcome before it can be employed in more general minimally-invasive procedures. This review overviews the roots of IGS in neurosurgery, provides examples of its use outside the brain, discusses the infrastructure required for successful implementation of IGS approaches and outlines the challenges that must be overcome for IGS to advance further.

Full Text Available Introduction: Diverticulitis is a common diagnosis in the emergency department (ED. Outpatient management of diverticulitis is safe in selected patients, yet the rates of admission and surgical procedures following ED visits for diverticulitis are unknown, as are the predictive patient characteristics. Our goal is to describe trends in admission and surgical procedures following ED visits for diverticulitis, and to determine which patient characteristics predict admission. Methods: We performed a cross-sectional descriptive analysis using data on ED visits from 2006-2011 to determine change in admission and surgical patterns over time. The Nationwide Emergency Department Sample database, a nationally representative administrative claims dataset, was used to analyze ED visits for diverticulitis. We included patients with a principal diagnosis of diverticulitis (ICD-9 codes 562.11, 562.13. We analyzed the rate of admission and surgery in all admitted patients and in low-risk patients, defined as age <50 with no comorbidities (Elixhauser. We used hierarchical multivariate logistic regression to identify patient characteristics associated with admission for diverticulitis. Results: From 2006 to 2011 ED visits for diverticulitis increased by 21.3% from 238,248 to 302,612, while the admission rate decreased from 55.7% to 48.5% (-7.2%, 95% CI [–7.78 to -6.62]; p<0.001 for trend. The admission rate among low-risk patients decreased from 35.2% in 2006 to 26.8% in 2011 (-8.4%, 95% CI [–9.6 to –7.2]; p<0.001 for trend. Admission for diverticulitis was independently associated with male gender, comorbid illnesses, higher income and commercial health insurance. The surgical rate decreased from 6.5% in 2006 to 4.7% in 2011 (-1.8%, 95% CI [–2.1 to –1.5]; p<0.001 for trend, and among low-risk patients decreased from 4.0% to 2.2% (- 1.8%, 95% CI [–4.5 to –1.7]; p<0.001 for trend. Conclusion: From 2006 to 2011 ED visits for diverticulitis increased

Surgical Procedures for BPH/LUTS: Impact on Male Sexual Health.

2014-01-01

Lower urinary tract symptoms (LUTS) because of benign prostatic hyperplasia (BPH) are a highly prevalent condition in men over 50 years old, and their incidence increases with age. The relationship between LUTS and erectile dysfunction (ED) has received increased attention recently because both diseases are highly prevalent, frequently co-associated in the same aging male group, and contribute significantly to the overall quality of life. In this review, we will examine the literature to assess the impact of surgical and minimally invasive treatments for LUTS/BPH on the male's sexual health. The impact of the various surgical and minimally invasive treatments for LUTS/BPH was reviewed to ascertain the impact on erectile and ejaculatory function. Sexual side effects of treatment for LUTS/BPH are underappreciated by urologists but likely play a prominent role in patient decision making, creating a disparity between provider and patient. Almost all accepted therapies for LUTS (surgical or medical) can affect some aspect of sexual health, making it imperative that health-care professionals understand their patients' concerns and motivations in these two linked diseases. The incidence of newly diagnosed postoperative ED in patients treated with monopolar transurethral resection (TURP) is around 14%, with reported values in various studies ranging from 0-32.5%, 7.7%, 6.5%, 17%, to 14%. Importantly, there is no significant difference reported between bipolar and monopolar TURP on sexual function. The risk of sexual side effects is an important one to consider in discussing the implications for any LUTS intervention as they play a prominent role in patient motivation, acceptance of bother and decision making concerning surgical intervention, thus creating a potential disparity between provider and patient.

In a previous report, we described a method of reconstruction using tumor-bearing autograft treated by liquid nitrogen for malignant bone tumor. Here we present the first case of bone deformity correction following a tumor-bearing frozen autograft via three-dimensional computerized reconstruction after multiple surgeries. A 16-year-old female student presented with pain in the left lower leg and was diagnosed with a low-grade central tibial osteosarcoma. Surgical bone reconstruction was performed using a tumor-bearing frozen autograft. Bone union was achieved at 7 months after the first surgical procedure. However, local tumor recurrence and lung metastases occurred 2 years later, at which time a second surgical procedure was performed. Five years later, the patient developed a 19° varus deformity and underwent a third surgical procedure, during which an osteotomy was performed using the Taylor Spatial Frame three-dimensional external fixation technique. A fourth corrective surgical procedure was performed in which internal fixation was achieved with a locking plate. Two years later, and 10 years after the initial diagnosis of tibial osteosarcoma, the bone deformity was completely corrected, and the patient's limb function was good. We present the first report in which a bone deformity due to a primary osteosarcoma was corrected using a tumor-bearing frozen autograft, followed by multiple corrective surgical procedures that included osteotomy, three-dimensional external fixation, and internal fixation.

Full Text Available Introduction. Hallux rigidus is observed in approximately 2.5% of the adult population. Until now neither a unified classification of hallux rigidus appears to exist nor any clear principles to choose the surgical method. The variety of clinical and radiological signs explains the difficulties in establishing a comprehensive classification system and in selection of the criteria for surgical procedure. There are few published reports about hallux rigidus percutaneous surgical treatment. Existing papers are dedicated to a limited number of percutaneous techniques.The purpose of this study was to evaluate the efficacy of percutaneous techniques for surgical treatment of the first metatarsophalangeal joint osteoarthritis; to specify factors determining the choice of procedure; to develop a grading system of the hallux rigidus severity which will help in selection of surgery. Materials and methods. Based on 156 surgeries (107 patients the author demonstrated the possibilities of percutaneous techniques in the surgical treatment of hallux rigidus of different stages as well as provided a brief description of used surgical techniques.Results. The mean age of patients was 48.8 years (ranged from 18 to 73. The mean follow-up was 7 months (ranged from 3 to 54. At the specified time the treatment outcomes of 103 patients (150 feet were analyzed. Mean hospital stay was 0.78 days (ranged from 0 to 1. No infectious or wound-healing problems were observed. Overall, the patients were completely satisfied with the outcomes of 89 surgical treatment, qualified satisfaction was reported with patients in respect of outcomes of 57 surgeries. Four unsatisfactory outcomes were observed. The role of the relatively long first metatarsal in the development of hallux rigidus was confirmed. Conclusion. Percutaneous techniques provide successful treatment for all stages of hallux rigidus. The choice of a specific surgical technique may be challenging and requires

In recent years, the live broadcasting of medical and surgical procedures has gained worldwide popularity. While the practice has appropriately been met with concerns for patient safety and privacy, many physicians tout the merits of real time viewing as a form of investigation, accelerating the process leading to adoption or abolition of newer techniques or technologies. This view introduces a new series of ethical considerations that need to be addressed. As such, this article considers, from a research ethics perspective, the use of live surgical procedure broadcast for investigative purposes. PMID:21292217

The number of men undergoing cosmetic surgery is increasing in North America. To determine the incidence and risk factors of major complications in males undergoing cosmetic surgery, compare the complication profiles between men and women, and identify specific procedures that are associated with higher risk of complications in males. A prospective cohort of patients undergoing cosmetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Gender specific procedures were excluded. Primary outcome was occurrence of a major complication in males requiring emergency room visit, hospital admission, or reoperation within 30 days of the index operation. Univariate and multivariate analysis evaluated potential risk factors for major complications including age, body mass index (BMI), smoking, diabetes, type of surgical facility, type of procedure, and combined procedures. Of the 129,007 patients, 54,927 underwent gender nonspecific procedures, of which 5801 (10.6%) were males. Women showed a higher mean age (46.4 ± 14.1 vs 45.2 ± 16.7 years, P procedures (RR 3.47), and combined procedures (RR 2.56). Aesthetic surgery in men is safe with low major complication rates. Modifiable predictors of complications included BMI and combined procedures.

Patients at High-Risk for Surgical Site Infection.

Mueck, Krislynn M; Kao, Lillian S

Surgical site infections (SSIs) are a significant healthcare quality issue, resulting in increased morbidity, disability, length of stay, resource utilization, and costs. Identification of high-risk patients may improve pre-operative counseling, inform resource utilization, and allow modifications in peri-operative management to optimize outcomes. Review of the pertinent English-language literature. High-risk surgical patients may be identified on the basis of individual risk factors or combinations of factors. In particular, statistical models and risk calculators may be useful in predicting infectious risks, both in general and for SSIs. These models differ in the number of variables; inclusion of pre-operative, intra-operative, or post-operative variables; ease of calculation; and specificity for particular procedures. Furthermore, the models differ in their accuracy in stratifying risk. Biomarkers may be a promising way to identify patients at high risk of infectious complications. Although multiple strategies exist for identifying surgical patients at high risk for SSIs, no one strategy is superior for all patients. Further efforts are necessary to determine if risk stratification in combination with risk modification can reduce SSIs in these patient populations.

Medical professional liability and adverse events in health care are major concerns worldwide and the analysis of claims for alleged defects in praxis is a potential source of knowledge. High rates of adverse events and complaints have been reported in surgical procedures. This article analyzes the claims registered by the Council of Medical Colleges in Catalonia between 1986 and 2012, and explores surgical procedures claimed (ICD- 9-CM coding), as well as the final outcome of the claim. Among the 5,419 records identified on surgical procedures, the interventions of the musculoskeletal system and skin and integument showed the highest frequencies. Interventions related to "non-curative" medicine should be emphasized because of their higher rates of economical agreement or condemnation outcomes, which were significantly higher for mastopexia. The results underscore the importance of the surgical area in medical professional liability and the high risk of payouts among those procedures belonging to the so-called "non-curative" medicine.

Mohanad Shukry

2010-03-01

Full Text Available Mohanad Shukry, Jeffrey A MillerUniversity of Oklahoma Health Sciences Center, Department of Anesthesiology, Children’s Hospital of Oklahoma, Oklahoma City, OK, USAAbstract: Dexmedetomidine was introduced two decades ago as a sedative and supplement to sedation in the intensive care unit for patients whose trachea was intubated. However, since that time dexmedetomidine has been commonly used as a sedative and hypnotic for patients undergoing procedures without the need for tracheal intubation. This review focuses on the application of dexmedetomidine as a sedative and/or total anesthetic in patients undergoing procedures without the need for tracheal intubation. Dexmedetomidine was used for sedation in monitored anesthesia care (MAC, airway procedures including fiberoptic bronchoscopy, dental procedures, ophthalmological procedures, head and neck procedures, neurosurgery, and vascular surgery. Additionally, dexmedetomidine was used for the sedation of pediatric patients undergoing different type of procedures such as cardiac catheterization and magnetic resonance imaging. Dexmedetomidine loading dose ranged from 0.5 to 5 μg kg-1, and infusion dose ranged from 0.2 to 10 μg kg-1 h-1. Dexmedetomidine was administered in conjunction with local anesthesia and/or other sedatives. Ketamine was administered with dexmedetomidine and opposed its bradycardiac effects. Dexmedetomidine may by useful in patients needing sedation without tracheal intubation. The literature suggests potential use of dexmedetomidine solely or as an adjunctive agent to other sedation agents. Dexmedetomidine was especially useful when spontaneous breathing was essential such as in procedures on the airway, or when sudden awakening from sedation was required such as for cooperative clinical examination during craniotomies.Keywords: dexmedetomidine, sedation, nonintubated patients

Esophageal achalasia is a relatively rare disease that occurs usually in middle-aged patients. The laparoscopic Heller-Dor (LHD) procedure is the gold-standard surgical treatment for esophageal achalasia. There are many studies on the pathology and surgical outcome of esophageal achalasia from various perspectives, but there are no studies on gender differences in both the pathology and surgical outcome. This study aimed to evaluate gender differences in the surgical outcome with the LHD procedure and in the pathology of esophageal achalasia patients. The study included 474 LHD-treated patients who were postoperatively followed up for 6 months or more. The patients were divided into 2 groups by gender, to compare the preoperative pathology, surgical outcome, symptom scores before and after LHD, symptom score improvement frequency, and patient satisfaction with the surgery. The study population consisted of 248 male and 226 female, having a mean age of 45.1 years. There were no gender differences in the preoperative pathology, but a significantly lower BMI (p achalasia were characterized by low BMI, less esophageal dilation, and increased frequency and severity of chest pain. LHD improved the chest pain in the female patients, whereas the surgical outcome and satisfaction with the surgery were excellent regardless of gender.

The need to involve patients more in decisions about their care, the ethical imperative and concerns about ligation and complaints has highlighted the issue of informed consent and how it is obtained. In order for a patient to make an informed decision about their treatment, they need appropriate discussion of the risks and benefits of the treatment. To explore doctors' perspectives of gaining informed consent for routine surgical procedures. Qualitative study using semi-structured interviews selected by purposive sampling. Data were analysed thematically. Twenty doctors in two teaching hospitals in the UK. Doctors described that while consent could be taken over a series of consultations, it was common for consent to be taken immediately prior to surgery. Juniors were often taking consent when they were unfamiliar with the procedure. Doctors used a range of communication techniques to inform patients about the procedure and its risks including quantifying risks, personalizing risk, simplification of language and use of drawings. Barriers to effective consent taking were reported to be shortage of time, clinician inexperience and patients' reluctance to be involved. Current consent processes do not appear to be ideal for many doctors. In particular, junior doctors are often not confident taking consent for surgical procedures and require more support to undertake this task. This might include written information for junior staff, observation by senior colleagues when undertaking the task and ward-based communication skills teaching on consent taking. © 2014 John Wiley & Sons Ltd.

In surgical procedures for cleft lip, surgeons attempt to use various skin incisions and small flaps to achieve a better and more natural shape postoperatively. They must understand the three-dimensional (3D) structure of the lips. However, they may have difficulty learning the surgical procedures precisely from normal textbooks with two-dimensional illustrations. Recent developments in 3D computed tomography (3D-CT) and laser stereolithography have enabled surgeons to visualize the structures of cleft lips from desired viewpoints. However, this method cannot reflect the advantages offered by specific surgical procedures. To solve this problem, we used the benefits offered by 3D computer graphics (3D-CG) and 3D animation. By using scanning 3D-CT image data of patients with cleft lips, 3D-CG models of the cleft lips were created. Several animations for surgical procedures such as incision designs, rotation of small skin flaps, and sutures were made. This system can recognize the details of an operation procedure clearly from any viewpoint, which cannot be acquired from the usual textbook illustrations. This animation system can be used for developing new skin-flap design, understanding the operational procedure, and using tools in case presentations. The 3D animations can also be uploaded to the World Wide Web for use in teleconferencing.

A number of compositional Medical Concept Representation systems are being developed. Although these provide for a detailed conceptual representation of the underlying information, they have to be translated back to natural language for used by end-users and applications. The GALEN programme has been developing one such representation and we report here on a tool developed to generate natural language phrases from the GALEN conceptual representations. This tool can be adapted to different source modelling schemes and to different destination languages or sublanguages of a domain. It is based on a multilingual approach to natural language generation, realised through a clean separation of the domain model from the linguistic model and their link by well defined structures. Specific knowledge structures and operations have been developed for bridging between the modelling 'style' of the conceptual representation and natural language. Using the example of the scheme developed for modelling surgical operative procedures within the GALEN-IN-USE project, we show how the generator is adapted to such a scheme. The basic characteristics of the surgical procedures scheme are presented together with the basic principles of the generation tool. Using worked examples, we discuss the transformation operations which change the initial source representation into a form which can more directly be translated to a given natural language. In particular, the linguistic knowledge which has to be introduced--such as definitions of concepts and relationships is described. We explain the overall generator strategy and how particular transformation operations are triggered by language-dependent and conceptual parameters. Results are shown for generated French phrases corresponding to surgical procedures from the urology domain.

Minimally invasive mitral valve repair procedures including MitraClip ® are becoming increasingly common. For cases of complex or diseased anatomy, clinicians may benefit from using a patient-specific cardiac phantom for training, surgical planning, and the validation of devices or techniques. An imaging compatible cardiac phantom was developed to simulate a MitraClip ® procedure. The phantom contained a patient-specific cardiac model manufactured using tissue mimicking materials. To evaluate accuracy, the patient-specific model was imaged using computed tomography (CT), segmented, and the resulting point cloud dataset was compared using absolute distance to the original patient data. The result, when comparing the molded model point cloud to the original dataset, resulted in a maximum Euclidean distance error of 7.7 mm, an average error of 0.98 mm, and a standard deviation of 0.91 mm. The phantom was validated using a MitraClip ® device to ensure anatomical features and tools are identifiable under image guidance. Patient-specific cardiac phantoms may allow for surgical complications to be accounted for preoperative planning. The information gained by clinicians involved in planning and performing the procedure should lead to shorter procedural times and better outcomes for patients.

Full Text Available Background: The aim of this study was to assess how the chosen socio-demographic factors effect the quality of life in the patients after gynaecological surgical procedures. Materials and Methods: Research was conducted in 2007 among 250 women operated in the Department of Reproduction and Gynaecology, the Pomeranian Medical University in Szczecin. In this survey-based study, we used a standardized quality of life questionnaire, the Women’s Health Questionnaire (WHQ, developed by Dr Myra Hunter at London University. Results: The most numerous patients were those with sleep disorders (38,8%, 37,6% of the surveyed complained of troublesome menstrual symptoms, 26,8% of respondents had disturbing somatic symptoms, short memory and problems with concentration. The lowest percentage of women (12,4% felt anxiety and fear associated with the past gynaecological surgical procedure. Conclusions: 1. General satisfaction and good disposition is declared by the majority of patients after gynaecological surgical procedures. 2. Age, education, having a partner, place of residence, and the number of children are the factors which have significant effect on the quality of life in women after gynaecological procedures.

Full Text Available In incidental aneurysms, endovascular treatment can lead to post-procedural headaches. We studied the difference of surgical clipping vs. endovascular coiling in concern to post-procedural headaches in patients with ruptured aneurysms. Sixtyseven patients with aneurysmal subarachnoidal haemorrhage were treated in our department from September 1st 2015 - September 1st 2016. 43 Patients were included in the study and the rest was excluded because of late recovery or highgrade subarachnoid bleedings. Twenty-two were surgical treated and twenty-one were interventionally treated. We compared the post-procedural headaches at the time points of 24 h, 21 days, and 3 months after treatment using the visual analog scale (VAS for pain. After surgical clipping the headache score decreased for 8.8 points in the VAS, whereas the endovascular treated population showed a decrease of headaches of 3.3 points. This difference was highly statistical significant and remained significant even after 3 weeks where the pain score for the surgically treated patients was 0.68 and for the endovascular treated 1.8. After 3 months the pain was less than 1 for both groups with surgically treated patients scoring 0.1 and endovascular treated patients 0.9 (not significant. Clipping is relieving the headaches of patients with aneurysm rupture faster and more effective than endovascular coiling. This effect stays significant for at least 3 weeks and plays a crucial role in stress relieve during the acute and subacute ICU care of such patients.

BACKGROUND: A eutectic mixture of lidocaine and prilocaine (EMLA) has been shown to be effective in reducing pain from needle sticks, including those associated with blood sampling and intravenous insertion. OBJECTIVE: To evaluate the effectiveness of EMLA cream applied before needle puncture for local anesthetic administration before minor surgical procedures in this double-blind, randomized, controlled, parallel-group study. MATERIALS AND METHODS: Patients were randomly assigned to receive EMLA or placebo cream (Aqueous) applied under an occlusive dressing. After the procedure, patients were asked to rate the needle prick and procedure pain on a visual analog scale (0=no pain; 10=maximum pain). RESULTS: A total of 94 minor surgical procedures (49 in EMLA and 45 in control) were performed. The mean needle-stick pain score in the EMLA group was significantly lower than in the control group (2.7 vs. 5.7, p<.001, Mann-Whitney U-test). There was also significantly lower procedure pain in the EMLA group than in the control group (0.83 vs. 1.86, p=.009). There were no complications associated with the use of EMLA. CONCLUSION: EMLA effectively reduces the preprocedural needle-stick pain and procedural pain associated with minor surgical procedures.

Methods: Evaluative study conducted at a teaching hospital in the south of Brazil in 2012. Data were collected by means of non-participant observation in 20 hip and knee replacement surgeries and an instrument that was created for research based on the checklist and used by the institution. Results: In the observed procedures (n = 20 there was significant adhesion (p<0.05 to the instrument in relation to the verification of documentation, fasting, hair removal in the surgical site, absence of nail varnish and accessories, identification of the patient and surgical site on admission to the surgical unit, availability of blood and functionality of materials. However, there was no significant adherence to the checklist in the operating room in relation to patient identification, procedure and laterality, team introduction, surgical break and materials count. Conclusion: The results showed that the items on the checklist were verified nonverbally and there was no significant adherence to the instrument.

Female-to-male gender-confirmation surgery (GCS) includes removal of breasts and female genitalia and complete genital and urethral reconstruction. With a multidisciplinary approach, these procedures can be performed in one stage, avoiding multistage operations. To present our results of one-stage sex-reassignment surgery in female-to-male transsexuals and to emphasize the advantages of single-stage over multistage surgery. During a period of 9 years (2007-2016), 473 patients (mean age = 31.5 years) underwent metoidioplasty. Of these, 137 (29%) underwent simultaneous hysterectomy, and 79 (16.7%) underwent one-stage GCS consisting of chest masculinization, total transvaginal hysterectomy with bilateral adnexectomy, vaginectomy, metoidioplasty, urethral lengthening, scrotoplasty, and implantation of bilateral testicular prostheses. All surgeries were performed simultaneously by teams of experienced gynecologic and gender surgeons. Primary outcome measurements were surgical time, length of hospital stay, and complication and reoperation rates compared with other published data and in relation to the number of stages needed to complete GCS. Mean follow-up was 44 months (range = 10-92). Mean surgery time was 270 minutes (range = 215-325). Postoperative hospital stay was 3 to 6 days (mean = 4). Complications occurred in 20 patients (25.3%). Six patients (7.6%) had complications related to mastectomy, and one patient underwent revision surgery because of a breast hematoma. Two patients underwent conversion of transvaginal hysterectomy to an abdominal approach, and subcutaneous perineal cyst, as a consequence of colpocleisis, occurred in nine patients. There were eight complications (10%) from urethroplasty, including four fistulas, three strictures, and one diverticulum. Testicular implant rejection occurred in two patients and testicular implant displacement occurred in one patient. Female-to-male transsexuals can undergo complete GCS, including mastectomy

To assess how much information communicated to patients is understood and retained after preoperative discussion of upper extremity procedures. A prospective study was designed by recruiting patients prior to undergoing upper extremity surgical procedures after a detailed discussion of their operative technique, postoperative care and treatment outcomes. Patients were given the same 20-item questionnaire to fill out twice, at two pre operative visits. An independent evaluator filled out a third questionnaire as a control. Various discussion points of the survey were compared among the 3 questionnaires and retained information and perceived comprehension were evaluated. The average patients' age was 50.3 (27-75) years The average time between the two surveys preoperative 1 and preoperative 2 was 40.7 (7-75) days,. The average patient had approximately 2 years of college or an associate's degree. Patients initially retained 73% (52-90%) of discussion points presented during preoperative 1 and 61% (36-85%) of the information at preoperative 2 p = .002. 50% of patients felt they understood 100% of the discussion, this dropped to only 10% at their preoperative 2 visit. 15% of our patients did not know what type of anesthesia they were having at preoperative 2. A communication barrier between patients and physicians exists when patients are informed about their preoperative surgical discussion. The retention of information presented is worsened with elapsing time from the initial preoperative discussion to the second preoperative visit immediately prior to surgery. Methods to enhance patients' retention of information prior to surgery must be sought and implemented which will improve patients' treatment outcome.

Full Text Available Background/Aim. Arthrosis of the hip is the most common cause of a hip joint disorders. The aim of this study was to present our experience in the application of a safe surgical dislocation of the hip in patients with minor morphological changes in the hip joint, which, through the mechanism of femoroacetabular impingement, cause damage to the acetabular labrum and adjacent cartilage as an early sign of the hip arthrosis. Methods. We have operated 51 patients with different morphological bone changes in the hip area and resultant soft tissue damage of the acetabular labrum and its adjacent cartilage. Surgical technique that we applied in this group of patients, was adapted to our needs and capabilities and it was minimaly modified compared to the original procedure. Results. The surgical technique presented in this paper, proved to be a good method of treatment of bone and soft tissue pathomorphological changes of the hip in patients with femoroacetabular impingement. We had no cases with avascular necrosis of the femoral head, and two patients had nonunion of the greater trochanter, 9 patients developed paraarticular ossification, without subjective symptoms, while 3 patients suffered from postoperative pain in the groin during more energetic physical activities. Conclusion. Utilization of our partly modified surgical technique of controlled and safe dislocation of the hip can solve all the bone and soft tissue problems in patients with femoroacetibular impingement to stop already developed osteoarthritis of the hip or to prevent mild form of it.

Introduction An increasing proportion of the population is living into their nineties and beyond. These high risk patients are now presenting more frequently to both elective and emergency surgical services. There is limited research looking at outcomes of general surgical procedures in nonagenarians and centenarians to guide surgeons assessing these cases. Methods A retrospective analysis was conducted of all patients aged ≥90 years undergoing elective and emergency general surgical procedures at a tertiary care facility between 2009 and 2015. Vascular, breast and endocrine procedures were excluded. Patient demographics and characteristics were collated. Primary outcomes were 30-day and 90-day mortality rates. The impact of ASA (American Society of Anesthesiologists) grade, operation severity and emergency presentation was assessed using multivariate analysis. Results Overall, 161 patients (58 elective, 103 emergency) were identified for inclusion in the study. The mean patient age was 92.8 years (range: 90-106 years). The 90-day mortality rates were 5.2% and 19.4% for elective and emergency procedures respectively (p=0.013). The median survival was 29 and 19 months respectively (p=0.001). Emergency and major gastrointestinal operations were associated with a significant increase in mortality. Patients undergoing emergency major colonic or upper gastrointestinal surgery had a 90-day mortality rate of 53.8%. Conclusions The risk for patients aged over 90 years having an elective procedure differs significantly in the short term from those having emergency surgery. In selected cases, elective surgery carries an acceptable mortality risk. Emergency surgery is associated with a significantly increased risk of death, particularly after major gastrointestinal resections.

Specialty procedures constitute one eighth of rural surgery practice. Currently, general surgeons intending to practice in rural hospitals may not get adequate training for specialty procedures, which they will be expected to perform. Better definition of these procedures will help guide rural surgery training. Current Procedural Terminology codes for all surgical procedures for 81% of North Dakota and South Dakota rural surgeons were entered into the Dakota Database for Rural Surgery. Specialty procedures were analyzed and compared with the Surgical Council on Resident Education curriculum to determine whether general surgery training is adequate preparation for rural surgery practice. The Dakota Database for Rural Surgery included 46,052 procedures, of which 5,666 (12.3%) were specialty procedures. Highest volume specialty categories included vascular, obstetrics and gynecology, orthopedics, cardiothoracic, urology, and otolaryngology. Common procedures in cardiothoracic and vascular surgery are taught in general surgical residency, while common procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology are usually not taught in general surgery training. Optimal training for rural surgery practice should include experience in specialty procedures in obstetrics and gynecology, orthopedics, urology, and otolaryngology. Copyright © 2012 Elsevier Inc.

Nitrous oxide (N2O) is the most commonly used inhalation anesthetic in dentistry and is commonly used in emergency centers and ambulatory surgery centers as well. When used alone, it is incapable of producing general anesthesia reliably. However, as a single agent, it has an impressive safety and is excellent for providing minimal and moderate sedation for apprehensive minor oral surgical procedure. In this article, action of N2O in overcoming the anxiety and pain of the patient during the minor oral surgery and its advantages and disadvantages, have been reviewed.

Surgical paients have been known to benefit immensely from psychological interventions. This study set out to assess the pre and postoperative anxiety levels and depression and the effect of cognitive therapy among Nigerian surgical patients. The effects of gender and educational status on perioperative anxiety and depression were also evaluated. The study utilized a controlled outcome design to evaluate the efficacy of self-instructional training (SIT) and rational emotive therapy (RET) in surgical patients. Preoperative anxiety and depression scores were used as co-variants. Thirty-three (33) elective surgical patients were sampled randomly, divided into 3 groups of eleven (11) patients each. Eight (8) subjects underwent gynaecological procedures while the remaining 25 subjects had general surgical procedures. The mean age was 32.72 +/- 15.83 years (range = 17-16 years.) The major instruments used in the study were the State Anxiety Subscale of the Speilberger State Trait Anxiety Inventory (STAI) and Hospital Anxiety and Depression Inventory. SIT had the potential to reduce anxiety level among subjects postoperatively (t = 2.06; df = 10; p < 0.05). The use of RET reduced depression among surgical patients (t = 1.23; df = 10; p < 0.05). It was concluded that surgical patients manifest varying degrees of anxiety preoperatively and postoperatively. Patient's pre and postoperative anxiety and depression can be reduced by the introduction of SIT and RET.

Full Text Available Background: Lagos University Teaching Hospital (LUTH is one of the foremost teaching institutions in Nigeria. It is a recognized training institution for residency training in Nigeria. However, a thorough evaluation of the procedures being undertaken by the orthopaedic teams in this centre and the impact on the type of training being passed on to the resident doctors in training is the focus of this paper. Objectives: To determine the pattern of procedures performed by the orthopaedic units of the Department of Surgery, LUTH with a view to import the findings in re-organizing its structure based on service requirement, manpower allocation and to make recommendation. Methods: We retrospectively reviewed data including age, sex, procedures and leading surgeons retrieved from all our operating theatres over a period from 1st January 2010 to 31st December 2011. The data retrieved was analyzed. Results: A total 741 procedures were performed over the 2 year period. More male patients (58.5% had procedures performed on them than the female patients. The mean age of patients treated was 37.2±15.5 years. Trauma related procedures accounted for 68.8% of the total procedures. Open reduction and internal fixation surgical operations were the most common trauma related procedure while ablative surgical operations following Diabetic Mellitus foot syndrome were the most common non-trauma related procedure performed. Conclusion: Trauma related surgery remains the most common procedures in our teaching hospital. Efforts should be made to increase the number of elective operations like Arthroplasties, Arthroscopic operations and Spinal axis correction operations being performed.

Bulking agents provide an alternative option in the management of women with stress urinary incontinence and they seem to have an important role in the management flow chart of SUI. However, evidence on this issue is scanty. The most important aspect is to understand whether bulking agents are comparable with the other first-line anti-incontinence surgical procedure (MUS, Burch colposuspension and pubovaginal slings). Hence, the primary aim of the current review was to assess the objective and subjective outcomes of bulking agents in comparison with the other surgical procedures for the treatment of SUI. PubMed and Medline were systematically searched and we included studies evaluating the use of bulking agents in comparison with other surgical approaches for either primary or recurrent treatment of female SUI. Three studies meeting the inclusion criteria were identified. Two of these studies were RCTs evaluating the use of bulking agents versus other surgical procedures for the treatment of primary female SUI; the remnant article was a retrospective cohort study that compared the effectiveness and safety of repeat midurethral sling with urethral bulking after failed midurethral sling. The combined results of all analyses showed that the objective recurrence rate of peri- or trans-urethral injections is significantly higher in comparison with the other surgical procedures. Similar findings were observed when considering separately the treatment for primary or recurrent SUI. Furthermore, lower subjective recurrence rate was observed among patients undergoing other surgical treatment in comparison with those undergoing bulking agents; however, this trend was not statistically significant. Moreover, patients undergoing injection of bulking agents experienced a lower rate of voiding dysfunctions in comparison to the control group. According to current evidence, bulking agents should not be proposed as first-line treatment in those women seeking permanent cure for both

HEMOPATCH (Sealing Hemostat is a novel, advanced hemostatic pad that is composed of a synthetic, protein-reactive monomer and a collagen backing. The active side is covered with a protein-reactive monomer: N-hydroxysuccinimide functionalized polyethylene glycol (NHS-PEG. NHS-PEG rapidly affixes the collagen pad to tissue to promote and maintain hemostasis. The combined action of the NHS-PEG and collagen is demonstrated to have benefit relative to other hemostatic agents in surgery and preclinical surgical models. This paper reviews the published investigations and case reports of the hemostatic efficacy of HEMOPATCH, wherein HEMOPATCH is demonstrated to be an effective, easy-to-use hemostatic agent in open and minimally invasive surgery of patients with thrombin- or platelet-induced coagulopathies.

The "TOMAX" (TO MAX-imize sensation, sexuality, and quality of life) procedure restores genital sensation in men with low spinal lesions, improving sexual health, as shown previously. It connects the dorsal nerve of the penis to the intact ipsilateral ilioinguinal nerve, unilaterally or bilaterally. This study reports on the technical aspects based on 43 TOMAX nerve transfers. In 40 patients with no penile but intact groin sensation, 43 nerve transfers were performed. Data on patient selection, surgical history, anatomy of the ilioinguinal nerve and dorsal nerve of the penis, unilateral or bilateral surgery, surgical technique, complications, and patient information were collected prospectively. Regardless of origin, all patients with no penile but good groin sensation are eligible for the procedure, provided the ilioinguinal nerve is not damaged because of former inguinal surgery or absent because of anatomical variations. Selection of a unilateral or bilateral procedure depends on the presence or absence of reflex erections and bulbocavernosus reflex. Preliminary experience with the first three bilateral cases shows that it is technically feasible, with encouraging results. The surgical technique has evolved (described in detail, including video) to enhance outcome and reduce complications. Patients are better informed, resulting in realistic expectations. This article synthesizes the procedural and technical experience of 43 TOMAX nerve transfers. Anyone skilled in peripheral nerve surgery and microsurgery can adopt this concept and further develop it. The TOMAX procedure can then be used to restore erogenous penile sensation and improve the quality of sexual health in patients with absent penile but good groin sensation.

Is mammary reconstruction with the anatomical Becker expander a simple procedure? Complications and hidden problems leading to secondary surgical procedures: a follow-up study.

Debate over the role of Becker expander implants (BEIs) in breast reconstruction is still ongoing. There are no clear indications for BEI use. The main indications for BEI use are one-stage breast reconstruction procedure and congenital breast deformities correction, due to the postoperative ability to vary BEI volume. Recent studies showed that BEIs were removed 5 years after mammary reconstruction in 68% of operated patients. This entails a further surgical procedure. BEIs should not, therefore, be regarded as one-stage prostheses. We performed a case-series study of breast reconstructions with anatomically shaped Becker-35™ implants, in order to highlight complications and to flag unseen problems, which might entail a second surgical procedure. A total of 229 patients, reconstructed from 2005 to 2010, were enrolled in this study. Data relating to implant type, volume, mean operative time and complications were recorded. All the patients underwent the same surgical procedure. The minimum follow-up period was 18 months. During a 5-year follow-up, 99 patients required secondary surgery to correct their complications or sequelae; 46 of them underwent BEI removal within 2 years of implantation, 56 within 3 years, 65 within 4 years and 74 within 5 years. Our findings show that two different sorts of complications can arise with these devices, leading to premature implant removal, one common to any breast implant and one peculiar to BEIs. The Becker implant is a permanent expander. Surgeons must, therefore, be aware that, once positioned, the Becker expander cannot be adjusted at a later date, as in two-stage expander/prosthesis reconstructions for instance. Surgeons must have a clear understanding of possible BEI complications in order to be able to discuss these with their patients. Therefore, only surgeons experienced in breast reconstruction should use BEIs. Copyright © 2013 British Association of Plastic, Reconstructive and Aesthetic Surgeons. Published by

Intratumoral lung abscess is a secondary lung abscess that is considered to be fatal. Therefore, surgical procedures, although high-risk, have sometimes been performed for intratumoral lung abscesses. However, no studies have examined the surgical outcomes of non-small cell lung cancer patients with intratumoral lung abscesses. The aim of this study was to investigate the surgical and survival outcomes of non-small cell lung cancer patients with intratumoral lung abscesses. Eleven consecutive non-small cell lung cancer patients with intratumoral lung abscesses, who had undergone pulmonary resection at our institution between January 2007 and December 2015, were retrospectively analysed. The post-operative prognoses were investigated and prognostic factors were evaluated. Ten of 11 patients were male and one patient was female. The median age was 64 (range, 52-80) years. Histopathologically, 4 patients had Stage IIA, 2 patients had Stage IIB, 2 patients had Stage IIIA, and 3 patients had Stage IV tumors. The median operative time was 346 min and the median amount of bleeding was 1327 mL. The post-operative morbidity and mortality rates were 63.6% and 0.0%, respectively. Recurrence of respiratory infections, including lung abscesses, was not observed in all patients. The median post-operative observation period was 16.1 (range, 1.3-114.5) months. The 5-year overall survival rate was 43.3%. No pre-operative, intra-operative, or post-operative prognostic factors were identified in the univariate analyses. Surgical procedures for advanced-stage non-small cell lung cancer patients with intratumoral lung abscesses, although high-risk, led to satisfactory post-operative mortality rates and acceptable prognoses.

The da Vinci Xi has been developed to overcome some of the limitations of the previous platform, thereby increasing the acceptance of its use in robotic multiorgan surgery. Between January 2015 and October 2015, 10 patients with synchronous tumors of the colorectum and others abdominal organs underwent robotic combined resections with the da Vinci Xi. Trocar positions respected the Universal Port Placement Guidelines provided by Intuitive Surgical for "left lower quadrant," with trocars centered on the umbilical area, or shifted 2 to 3 cm to the right or to the left, depending on the type of combined surgical procedure. All procedures were completed with the full robotic technique. Simultaneous procedures in same quadrant or left quadrant and pelvis, or left/right and upper, were performed with a single docking/single targeting approach; in cases of left/right quadrant or right quadrant/pelvis, we performed a dual-targeting operation. No external collisions or problems related to trocar positions were noted. No patient experienced postoperative surgical complications and the mean hospital stay was 6 days. The high success rate of full robotic colorectal resection combined with other surgical interventions for synchronous tumors, suggest the efficacy of the da Vinci Xi in this setting.

PURPOSE OF THE STUDY Thoracic trauma, one of the most frequent injuries in patients with multiple traumata, is found in 50 to 80% of these patients and it is crucial for the patient's prognosis. It accounts for 25% of all death from polytraumatic injuries. The aim of this retrospective study was an analysis of the occurrence of chest injuries in polytrauma patients and their surgical treatment in the Trauma Centre or Department of Surgery of the University Hospital Pilsen in a five-year period. MATERIAL AND METHODS Patients with injuries meeting the definition of polytrauma and an Injury Severity Score (ISS) ≥16 were included. The demographic characteristics, mechanism of multiple trauma, ISS value and chest injury were recorded in each patient. The number of injured patients in each year of the study was noted. In the patients with chest injury, the type of injury and method of treatment were assessed. The therapy was further analysed including its timing. The number of deaths due to polytrauma involving chest injury, the cause of death and its time in relation to the patient's admission to the Trauma Centre were evaluated. RESULTS In the period 2010-14, 513 polytrauma patients were treated; of them 371 (72.3%) were men with an average age of 40.5 years. The most frequent cause of injury was a traffic accident (74%). The average ISS of the whole group was 35 points. Chest injury was diagnosed in 469 patients (91.4%) of whom only five (1.1%) had penetrating injury. Pulmonary contusion was most frequent (314 patients; 67%). A total of 212 patients with chest injury underwent surgery (45.2%); urgent surgery was performed in 143 (67.5%), acute surgery in 49 (23.1%) and delayed surgery in 63 (29.7%) patients. Chest drainage was the major surgical procedure used in the whole group. Of 61 patients who died, 52 had chest injury. In this subgroup the most frequent cause of death was decompensated traumatic shock (26 patients; 50%). In the whole group, 32 polytrauma

Materials and Methods: This is a prospective descriptive study. This study was conducted in 2012 in the North West of Iran. The population consisted of patients who had undergoing surgery in α university of medical science`s hospital which have surgical department. In this study, 1125 patients underwent surgery within 3 months were studied. Data collection tool was designed based on WHO model and Surgcical Care and Outcomes Assessment Program(SCOAP. Data analysis was performed using the SPSS-20 statistical software and logistic regression analysis was used to calculate P values for each comparison. Results: No significant differences between patients in the two periods (before and after There was. All complications rate reduced from 11 percent to 4 percent after the intervention by checklist (p<0.001. In the all hospitals mortality rate was decreased from 3.44% to 1.3% (p <0.003. Overall rate of surgical site infection and unplanned return to the operating room was reduced (p<0.001 and p<0.046. Conclusion: Many people every year due to lack of safety in hospitals, lose their lives. Despite the risks, such as leaving surgery sets in patient body and wrong surgery is due to lack of proper safety programs during surgery. By using safety checklist in all hospitals mortality rate and complications was reduced but this reduction was extremely in α3 hospital (from 5.2% to 1.48%.

We aimed to develop a model for predicting in-hospital mortality of cirrhotic patients following major surgical procedures using a large sample of patients derived from a Japanese nationwide administrative database. We enrolled 2197 cirrhotic patients who underwent elective (n = 1973) or emergency (n = 224) surgery. We analyzed the risk factors for postoperative mortality and established a scoring system for predicting postoperative mortality in cirrhotic patients using a split-sample method. In-hospital mortality rates following elective or emergency surgery were 4.7% and 20.5%, respectively. In multivariate analysis, patient age, Child-Pugh (CP) class, Charlson Comorbidity Index (CCI), and duration of anesthesia in elective surgery were significantly associated with in-hospital mortality. In emergency surgery, CP class and duration of anesthesia were significant factors. Based on multivariate analysis in the training set (n = 987), the Adequate Operative Treatment for Liver Cirrhosis (ADOPT-LC) score that used patient age, CP class, CCI, and duration of anesthesia to predict in-hospital mortality following elective surgery was developed. This scoring system was validated in the testing set (n = 986) and produced an area under the curve of 0.881. We also developed iOS/Android apps to calculate ADOPT-LC scores to allow easy access to the current evidence in daily clinical practice. Patient age, CP class, CCI, and duration of anesthesia were identified as important risk factors for predicting postoperative mortality in cirrhotic patients. The ADOPT-LC score effectively predicts in-hospital mortality following elective surgery and may assist decisions regarding surgical procedures in cirrhotic patients based on a quantitative risk assessment. © 2016 The Authors Hepatology Research published by John Wiley & Sons Australia, Ltd on behalf of Japan Society of Hepatology.

Full Text Available Nitrous oxide (N 2 O is the most commonly used inhalation anesthetic in dentistry and is commonly used in emergency centers and ambulatory surgery centers as well. When used alone, it is incapable of producing general anesthesia reliably. However, as a single agent, it has an impressive safety and is excellent for providing minimal and moderate sedation for apprehensive minor oral surgical procedure. In this article, action of N 2 O in overcoming the anxiety and pain of the patient during the minor oral surgery and its advantages and disadvantages, have been reviewed.

Several suspension methods are used to try to prevent pelvic organ prolapse (POP) after hysterectomy. We aimed to evaluate agreement on terminology and surgical procedure of these methods. We randomly chose 532 medical records of women with a history of hysterectomy from the Danish Hysterectomy and Hysteroscopy Database (DHHD). Additionally, we video-recorded 36 randomly chosen hysterectomies. The hysterectomies were registered in the DHHD. The material was categorized according to predefined suspension methods. Agreement compared suspension codes in DHHD (gynecologists' registrations) with medical records (gynecologists' descriptions) and with videos (reviewers' categorizations) respectively. Whether the vaginal vault was suspended (pooled suspension) or not (no suspension method + not described) was analyzed, in addition to each suspension method. Regarding medical records, agreement on terminology was good among patients undergoing pooled suspension in cases of hysterectomy via the abdominal and vaginal route (agreement 78.7, 92.3%). Regarding videos, agreement on surgical procedure was good among pooled suspension patients in cases of hysterectomy via the abdominal, laparoscopic, and vaginal routes (agreement 88.9, 97.8, 100%). Agreement on individual suspension methods differed regarding both medical records (agreement 0-90.1%) and videos (agreement 0-100%). Agreement on terminology and surgical procedure regarding suspension method was good in respect of pooled suspension. However, disagreement was observed when individual suspension methods and operative details were scrutinized. Better consensus of terminology and surgical procedure is warranted to enable further research aimed at preventing POP among women undergoing hysterectomy.

Pancreatic duct stone (PDS) is a common complication of chronic pancreatitis. Surgery is a common therapeutic option for PDS. In this study we assessed the surgical procedures for PDS in patients with chronic pancreatitis at our hospital. Between January 2004 and September 2009, medical records from 35 patients diagnosed with PDS associated with chronic pancreatitis were retrospectively reviewed and the patients were followed up for up to 67 months. The 35 patients underwent ultrasonography, computed tomography, or both, with an overall accuracy rate of 85.7%. Of these patients, 31 underwent the modified Puestow procedure, 2 underwent the Whipple procedure, 1 underwent simple stone removal by duct incision, and 1 underwent pancreatic abscess drainage. Of the 35 patients, 28 were followed up for 4-67 months. There was no postoperative death before discharge or during follow-up. After the modified Puestow procedure, abdominal pain was reduced in patients with complete or incomplete stone clearance (P>0.05). Steatorrhea and diabetes mellitus developed in several patients during a long-term follow-up. Surgery, especially the modified Puestow procedure, is effective and safe for patients with PDS associated with chronic pancreatitis. Decompression of intraductal pressure rather than complete clearance of all stones predicts postoperative outcome.

Nutritional status of patients significantly affects the outcome of surgical treatment, whether it's about being obese or malnutrition with loss of muscle mass. Inadequate nutritional support in the perioperative period compromises surgical procedures even in patients who are adequately nourished. In this paper, particular attention was paid to malnourished patients, and their incidence in population hospitalized in surgical wards can be high up to 30%. Special emphasis was paid to the appropriateness of preoperative fasting and to the acceptance of new knowledge in this area of treatment. The aim of this working group was to make guidelines for perioperative nutritional support with different modalities of enteral nutrition. The development of these guidelines was attended by representatives of Croatian Medical Association: Croatian Society for Digestive Surgery, Croatian Society for Clinical Nutrition, Croatian Society of Surgery, Croatian Society for Endoscopic Surgery, Croatian Trauma Society and the Croatian Society of Anesthesiology and Intensive Care. The guidelines are designed as a set of questions that arise daily in clinical practice when preparing patients for surgery and after the surgical treatment, which relate to the assessment of nutritional status, perioperative nutritional support, duration of preoperative fasting period and the selection of food intake route. Assessment of nutritional status and the use of different modes of enteral nutrition should enter into standard protocols of diagnosis and treatment in the Croatian hospitals.

When soft-tissue sarcomas occur near neurovascular structures, preoperative images cannot always reveal the accurate relationship between the tumor and these structures. Therefore, in some patients, neurovascular structures are sacrificed unnecessarily. In other patients, neurovascular structures are preserved with an inappropriate margin, followed by local recurrence. The objective of this study was to evaluate a new surgical method, "in situ preparation" (ISP), which enables the preparation of neurovascular bundles and the intraoperative evaluation of the surgical margin without contamination by tumor cells. With this method, additional procedures, including pasteurization, alcohol soaking, and distilled water soaking of the preserved neurovascular bundle can also be performed to preserve the continuity of vessels. Between April 1992 and December 1998, 18 patients with soft-tissue sarcoma were operated on using ISP. The tumor and neurovascular structure were lifted en bloc from the surgical bed and separated from the field by the use of a vinyl sheet. The consistency of the neurovascular structures was preserved. The tissue block could be freely turned around and the neurovascular structure was separated from the block through the nearest approach. The margin between the tumor and neurovascular structure was evaluated, and an additional procedure, such as pasteurization, alcohol soaking or distilled water soaking, was performed, according to the safety of the surgical margin. Only one patient showed recurrence after ISP. Complications after ISP were arterial occlusion in two patients and nerve palsy in three patients. The main cause of these complications was the long period of pasteurization; modified additional procedures could prevent such complications. ISP is a useful method with which to ensure a safe surgical margin and good functional results.

Single visit surgery (SVS) consists of same-day pre-operative assessment and operation with telephone post-operative follow-up. This reduces family time commitment to 1 hospital trip rather than 2-3. We began SVS for ambulatory patients with clear surgical indications in 2013. We sought to determine family satisfaction, cost savings to families, and institutional financial feasibility of SVS. SVS patients were compared to age/case matched conventional surgery (CS) patients. Satisfaction was assessed by post-operative telephone survey. Family costs were calculated as the sum of lost revenue (based on median income) and transportation costs ($0.50/mile). Satisfaction was high in both groups (98% for SVS vs. 93% for CS; p=0.27). 40% of CS families indicated that they would have preferred SVS, whereas no SVS families indicated preference for the CS option (p<0.001). Distance from the hospital did not correlate with satisfaction. Estimated cost savings for an SVS family was $188. Reimbursement, hospital and physician charges, and day-of-surgery cancellation rates were similar. SVS provides substantial cost savings to families while maintaining patient satisfaction and equivalent institutional reimbursement. SVS is an effective approach to low-risk ambulatory surgical procedures that is less disruptive to families, facilitates access to pediatric surgical care, and reduces resource utilization.

To evaluate if the improved accelerated osteogenic orthodontics (IAOO) procedure could speed Class III surgical patients' preoperative orthodontic treatment duration and, if yes, to what extent. This study was also designed to determine whether or not an IAOO procedure affects the tooth-moving pattern during extraction space closure. The samples in this study consisted of 24 Class III surgical patients. Twelve skeletal Class III surgery patients served as an experimental group (group 1) and the others as a control group (group 2). Before treatment, the maxillary first premolars were removed. For group 1, after the maxillary dental arch was aligned and leveled (T2), IAOO procedures were performed in the maxillary alveolar bone. Except for this IAOO procedure in group 1, all 24 patients experienced similar combined orthodontic and orthognathic treatment. Study casts of the maxillary dentitions were made before orthodontic treatment (T1) and after extraction space closure (T3). All of the casts were laser scanned, and the amount of movement of the maxillary central incisor, canine, and first molar, as well as arch widths, were digitally measured and analyzed by using the three-dimensional model superimposition method. The time durations T3-T2 were significantly reduced in group 1 by 8.65 ± 2.67 months and for T3-T1 were reduced by 6.39 ± 2.00 months (P teeth movement in the sagittal, vertical, and transverse dimensions between the two groups (P > .05). The IAOO can reduce the surgical orthodontic treatment time for the skeletal Class III surgical patient by more than half a year on average. The IAOO procedures do not save anchorage.

After the introduction of mesh in inguinal hernia repair, the focus to improve surgical technique has changed from recurrence to chronic postoperative inguinal pain. At present, the most common surgical techniques are the Lichtenstein hernioplasty and total extraperitoneal procedure. Both techniques have their own specific disadvantages, with regard to potential nerve damage and the necessity of general anesthesia, respectively. The goal of this study was to evaluate the results of a new technique in which the inguinal nerves are not at risk, and in which general anesthesia is not needed: trans rectus sheath extraperitoneal procedure (TREPP). Between 2006 and 2010, a total of 1,000 patients were treated for inguinal hernia with TREPP. A questionnaire concerning pain, sensibility changes, patient satisfaction, and recurrence was sent to all patients. The questionnaire was completed by 932 patients. Almost 90% of patients had not experienced any pain since the surgical procedure; 8% of patients reported experiencing some pain, but less than preoperatively; and 2% of patients reported an increase in pain postoperatively. Recurrence occurred in 1 and 3% were unsure about this. Reduced sensibility of the scar, scrotum, and upper leg was reported by 12.4, 1.4, and 1.5%, respectively. Overall, 97.4% of patients were satisfied with the results of the surgical procedure. The time period in which TREPP was performed was not associated with any of the outcome measures. TREPP has proven to be a feasible new technique for inguinal hernia repair, with excellent results, justifying a randomized controlled trial in which TREPP should be compared with standard techniques.

Full Text Available Background. Endometriosis is nowadays probably the most frequent cause of infertility or subfertility and is revealed in approximately 30–40% of infertile women. The association between fertility and minimal or mild endometriosis remains unclear and controversial. Moderate and severe forms of the disease distort anatomical relations in the minor pelvis, resulting in infertility. The goals of endometriosis treatment are relief of pain symptoms, prevention of the disease progression and fertility improvement. Treatment of stages I and II endometriosis (according to the R-AFS classification may be expectative, medical or surgical. In severely forms of the disease (stage III and IV the method of choice is surgical treatment. Combined medical and surgical treatment is justified only in cases, in which the complete endometriotic tissue removal is not possible or recurrence of pain symptoms occur. Nowadays, laparoscopic surgical treatment is the golden standard being the diagnostic and therapeutic tool during the same procedure. The aim of this study was to evaluate the fertility rate after surgical treatment of different stages of endometriosis.Patients and methods. In prospectively designed study 100 infertile women were included. The only known cause of infertility was endometriosis. In group A there were 51 patients with stage I and II endometriosis, whereas in group B there were 49 patients with stage III and IV of the disease. Endometriosis was diagnosed and treated laparoscopically. Endometriotic implants were removed either with bipolar coagulation or CO2 laser vaporisation, whereas adhesions were sharp or blunt dissected, and endometriomas stripped out of ovaries. Pregnancy rates were calculated for both groups of patients, and statistically compared between the groups.Results. Mean age of patients was 29.25 (SD ± 4.08 years and did not significantly differ between the groups of patients (29.5 years in group A and 29 years in group B. In

The diagnosis and surgical treatment of patients with Marfan syndrome remain controversial. It is of utmost importance to identify patients at risk for acute aortic events to establish the correct surgical timing and the appropriate surgical treatment. From May 2008 to December 2012, 500 patients were screened at the Marfan Presidium of the Tor Vergata University Hospital of Rome (Italy). Patients were evaluated by a cardiac surgeon, including echocardiographic, orthopedic, ophthalmologic and dental examinations. All patients received genetic counseling, and genetic sampling was performed if appropriate. The diagnosis of Marfan syndrome was confirmed in 146 patients (29.2%). Fifty-four patients (37%) underwent cardiac surgery on the aortic root, 4 patients had surgery on the mitral valve, 13 patients had combined surgery; 11 cases were emergent surgery for acute aortic dissection. Twenty-eight patients (52%) were operated on at our Division: 13 underwent valve-sparing aortic root replacement (David procedure), 1 underwent Yacoub remodeling procedure and 14 underwent Bentall procedure. Following the establishment of the Marfan Center, the David aortic valve-sparing operation was the most frequently performed procedure compared to the previous period of surgical activity (63 vs 22%, psyndromes. Early surgical treatment is recommended in these patients to achieve optimal results of valve-sparing procedures and life-saving management, especially for patients who live far away from a cardiac surgery center.

To assess the role of appendectomy in the surgical procedures for ovarian cancer, we evaluated retrospectively the clinical charts of 435 patients who underwent surgery after diagnosis of ovarian cancer. The appendix was removed in 160 cases and pathological examination revealed 37 with metastatic implants (23%). All the patients with appendiceal metastases showed advanced disease (stages III-IV) with an incidence of 43%. Ninety-one percent (31/34) of the tumors with appendiceal involvement at the staging operation were of the serous cell type and grade II or III. No case with early stage, right ovary carcinoma showed appendiceal metastatic foci, denying the existence of a preferential lymphatic pathway. Microscopic involvement was found only in 4 patients with advanced disease (11.7%). No intra- or postoperative complication directly related to the appendectomy was recorded. We conclude, with these results, that appendectomy should be part of the cytoreductive operation for ovarian cancer.

Surgery is the cornerstone for clinical management of patients with borderline ovarian tumors (BOT). As these patients have an excellent overall prognosis, perioperative morbidity is the critical point for decision making when the treatment strategy is developed and the primary surgical approach is defined. Clinical and surgical parameters of patients undergoing surgery for primary BOT at our institutions between 1993 and 2008 were analyzed with regard to perioperative morbidity depending on the surgical approach (laparotomy vs. laparoscopy). A total of 105 patients were analyzed (44 with primary laparoscopy [42%], 61 with primary laparotomy [58%]). Complete surgical staging was achieved in 33 patients at primary surgical approach (31.4%) frequently leading to formal indication of re-staging procedures. Tumor rupture was significantly more frequent during laparoscopy compared to laparotomy (29.5% vs. 13.1%, p = 0.038) but no other intraoperative complications were seen in laparoscopic surgery in contrast to 7 of 61 laparotomies (0% vs. 11.5%, p = 0.020). Postoperative complication rates were similar in both groups (19.7% vs. 18.2%, p = 0.848). Irrespective of the surgical approach, surgical management of BOT has acceptable rates of perioperative complications and morbidity. Choice of initial surgical approach can therefore be made independent of complication-concerns. As the recently published large retrospective AGO ROBOT study observed similar oncologic outcome for both approaches, laparoscopy can be considered for staging of patients with BOT if this appears feasible. An algorithm for the surgical management of BOT patients has been developed.

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

Objective assessment of surgical skills is resource intensive and requires valuable time of expert surgeons. The goal of this study was to assess the ability of a large group of laypersons using a crowd-sourcing tool to grade a surgical procedure (cricothyrotomy) performed on a simulator. The grading included an assessment of the entire procedure by completing an objective assessment of technical skills survey. Two groups of graders were recruited as follows: (1) Amazon Mechanical Turk users and (2) three expert surgeons from University of Washington Department of Otolaryngology. Graders were presented with a video of participants performing the procedure on the simulator and were asked to grade the video using the objective assessment of technical skills questions. Mechanical Turk users were paid $0.50 for each completed survey. It took 10 h to obtain all responses from 30 Mechanical Turk users for 26 training participants (26 videos/tasks), whereas it took 60 d for three expert surgeons to complete the same 26 tasks. The assessment of surgical performance by a group (n = 30) of laypersons matched the assessment by a group (n = 3) of expert surgeons with a good level of agreement determined by Cronbach alpha coefficient = 0.83. We found crowd sourcing was an efficient, accurate, and inexpensive method for skills assessment with a good level of agreement to experts' grading. Copyright © 2015 Elsevier Inc.

It is recommended to correct intravenous induction doses by up to 50% for patients older than 65 years. The objectives were to determine (a) the degree to which anesthesia providers correct induction doses for age and (b) additionally adjust for American Society of Anesthesiologists physical status (ASA-PS) class (severity of illness) and (c) whether postinduction hypotension is more common among patients aged >65. Retrospective chart review. Academic medical center. A total of 1869 adult patients receiving general anesthesia for GI surgical procedures from February 2013 to January 2014. Patients were divided into 3 age groups (age 80, which was still in less than the recommendations. An inverse relationship was observed between propofol dosing and ASA-PS class, but no consistent relationship was noted for fentanyl and midazolam. There were a significantly larger drop in mean arterial pressure and a greater likelihood of hypotension following induction in patients aged 65-79 years and >80 years as compared with those aged <65 years. This study shows that the administered dose of anesthetic induction agents is significantly higher than that recommended for patients older than 65 years. This failure to age-adjust dose may contribute to hypotensive episodes. Copyright © 2016 Elsevier Inc. All rights reserved.

2012-01-01

Background: Spondylolithesis is forward slipping of upper vertebra in relation to its lower one, which at times requires surgery. The objective of present study is to document the outcome of surgical treatment in spondylolisthesis of lumbosacral region. Methods: We reviewed outcome of surgery in 45 patients with spondylolisthesis. Improvement in pain intensity, neurological status and union achieved after surgery was studied. All patients requiring surgical treatment were included in the study. The patients were operated by single spine surgeon. A proforma was made for each patient and records were kept in a custom built Microsoft access database. Results: Majority of our patient were in 4th and 5th decade with some male domination. Pain was main indication for surgery which was excruciating in 6, severe in 33, and moderate in 6 cases. The neurological status was normal in 34 cases while 11 patients had some deficit. L5-S1 was affected in 26, L4-L5 in 13 and multi or high level was found in rest of cases. Slip grade was measured with Meyerding grades, 18 had grade II, 15 had I, 9 had III and 3 had IV spondylolisthesis. Posterior lumbar inter body fusion (PLIF) was done in 24 patients, posterolateral, transforaminal lumbar inter body and anterior inter body fusion in others. Translaminar screw fixation, transpedicular transdiscal transcorporial and Delta fixation in some cases. Pedicle screw fixation was done in most cases, AO fixator internae and 4.5 mm screw in others. Average follow up was 2 years and 5 months, max 5 years and minimum 6 months. Pain relief was achieved in 82%, neurological improvement 60% and union in 91% cases. There was no deterioration of neurological status, two implant failure and one wound infection. Conclusion: Surgical procedure for Spondylolisthesis must be individualised. Young patients with spondylolysis can be treated with osteosynthesis and sparing of motion segment. PLIF provides satisfactory results in majority of low to moderate

Graduate medical education has traditionally required long work hours, allowing trainees little time for adequate rest. Based on concerns over performance deterioration with sleep deprivation and its effect on patient outcomes, duty hour restrictions have been mandated. We sought to characterize complications from otolaryngology key indicator procedures performed before and after duty hour reform. Retrospective cross-sectional analysis of National Inpatient Sample (NIS). The NIS was queried for procedure codes associated with head and neck key indicator groupings for the years 2000-2002 (45,363 procedures) and 2006-2008 (51,144 procedures). Hospitals were divided into three groups: nonteaching hospitals (NTH), teaching hospitals without otolaryngology programs (TH), and teaching hospitals with otolaryngology programs (TH-OTO). Surgical complication rates, length of stay, and mortality rates were analyzed using logistic and linear regression. The number of procedures increased (12.7%), with TH-OTO contributing more in postrestriction years (21% to 30%). Overall complication rates between the two periods revealed no difference, regardless of hospital setting. Subset analysis showed some variation within each complication within each grouping. Length of stay increased at TH-OTO (2.75 to 2.78 days) and decreased at NTH (2.28 to 2.24 days) and TH (2.39 to 2.36 days). Mortality did not increase among the three hospital types (NTH, P key indicator procedures. Moreover, concerns about reduced surgical case numbers appear unfounded, especially for otolaryngology programs. 2c Laryngoscope, 127:1797-1803, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

To compare the safety and efficacy of an inexpensive-modified transobturator vaginal tape procedure with the transobturator tension-free vaginal tape (TVT-O) procedure for the surgical treatment of female stress urinary incontinence (SUI). Patients with SUI were randomly allocated to either the test group receiving the inexpensive-modified transobturator vaginal tape procedure or the control group receiving the GYNECARE TVT-O procedure. Treatment outcomes and Quality-of-life scores were recorded and analyzed between two groups. A total of 156 patients were enrolled in this trial. Eighty patients underwent the modified transobturator vaginal tape procedure. Among them 75(93.8%) were cured and 5(6.2%) were improved. The rest of the 76 patients underwent the GYNECARE TVT-O procedure with a 92% (70 of 76) cure rate and an 8% (6 of 76) improvement rate. No inefficient or aggravated cases occurred in both groups. The success rates between groups had no significant statistic difference (p > 0.05). The operative time, blood loss, hospital stay, and medical cost were significantly lower in the test group (p < 0.01); the increases in Quality-of-life scores were comparable between groups. The modified transobturator vaginal tape procedure is an efficacious and economic surgical treatment for female SUI. Copyright © 2011. Published by Elsevier B.V.

The main complication of surgery for inguinal hernia is chronic postoperative pain. This is often reported following the Lichtenstein procedure. A new, open surgical technique for the repair of inguinal hernia has been developed. This procedure is called the transrectus sheath preperitoneal procedure (TREPP). At TREPP a lightweight mesh with a ring made of memory metal is introduced into the preperitoneal space through the transrectus sheath. The first results of this operative technique are very promising: short operation time, short learning curve and not many patients with chronic postoperative pain. In a randomised, multi-centre study which will start mid-2013 (ISRCTN18591339), the TREPP procedure is compared with the transinguinal preperitoneal procedure. The primary outcome measure of this study is chronic postoperative pain.

Full Text Available Abstract Background Only 50% of gallbladder cancers (GBC are recognized before operation and the remaining tumors are diagnosed during surgery or afterwards by the pathologist. These situations may demand substantial modifications of the proceeding during surgery as well as the need for reoperation in some cases. Therefore, the time of diagnosis may strongly influence the surgical management of GBC and the prognosis of the patients. Methods Records and follow-up of 152 patients with gallbladder carcinoma who underwent surgery between 1980 and 2004 were examined according to the time of diagnosis, TNM staging system, surgical procedures, morbidity and predictors of survival. There were 76 patients with preoperative diagnosis of GBC (50%; group1, 44 patients with intraoperative diagnosis (29%; group 2 and 32 patients (21%; group 3 with postoperatively incidental finding of GBC. In all cases radical resection of the GBC was intended, except in 5 patients from group 1. Surgical procedures comprised from simple cholecystectomy to multivisceral resections. Results Overall 5-year survival rate was 7% with a significantly better median survival in group 3 (53.2 month, when compared to only 6.1 month (group 2 and 5.4 month (group 1, respectively. Findings at operation forced significant modifications of the surgical strategy in 85%. Complete resection of GBC was achieved in 38% of the patients. Stage- dependent survival was comparable between the groups following R0 resection. Tumor stage, in particular the nodal status and radicality of the procedure, but not the time of diagnosis were the most powerful predictors of outcome. Conclusions Complete tumor resection may provide long-term survival even in locally advanced GBC. Although the time of diagnosis of GBC causes significant changes of the intended procedures during and after surgery, it has no influence on the prognosis provided that radical (R0 resection was accomplished.

Serious, preventable surgical events, termed never events, continue to occur despite considerable patient safety efforts. To examine the incidence and root causes of and interventions to prevent wrong-site surgery, retained surgical items, and surgical fires in the era after the implementation of the Universal Protocol in 2004. We searched 9 electronic databases for entries from 2004 through June 30, 2014, screened references, and consulted experts. Two independent reviewers identified relevant publications in June 2014. One reviewer used a standardized form to extract data and a second reviewer checked the data. Strength of evidence was established by the review team. Data extraction was completed in January 2015. Incidence of wrong-site surgery, retained surgical items, and surgical fires. We found 138 empirical studies that met our inclusion criteria. Incidence estimates for wrong-site surgery in US settings varied by data source and procedure (median estimate, 0.09 events per 10,000 surgical procedures). The median estimate for retained surgical items was 1.32 events per 10,000 procedures, but estimates varied by item and procedure. The per-procedure surgical fire incidence is unknown. A frequently reported root cause was inadequate communication. Methodologic challenges associated with investigating changes in rare events limit the conclusions of 78 intervention evaluations. Limited evidence supported the Universal Protocol (5 studies), education (4 studies), and team training (4 studies) interventions to prevent wrong-site surgery. Limited evidence exists to prevent retained surgical items by using data-matrix-coded sponge-counting systems (5 pertinent studies). Evidence for preventing surgical fires was insufficient, and intervention effects were not estimable. Current estimates for wrong-site surgery and retained surgical items are 1 event per 100,000 and 1 event per 10,000 procedures, respectively, but the precision is uncertain, and the per-procedure

Postoperative unplanned readmissions are costly and decrease patient satisfaction; however, little is known about this complication in pediatric surgery. The purpose of this study was to determine rates and predictors of unplanned readmission in a multi-institutional cohort of pediatric surgical patients. Unplanned 30-day readmissions following general and thoracic surgical procedures in children readmission per 30 person-days were determined to account for varied postoperative length of stay (pLOS). Patients were randomly divided into 70% derivation and 30% validation cohorts which were used for creation and validation of a risk model for readmission. Readmission occurred in 1948 (3.6%) of 54,870 children for a rate of 4.3% per 30 person-days. Adjusted predictors of readmission included hepatobiliary procedures, increased wound class, operative duration, complications, and pLOS. The predictive model discriminated well in the derivation and validation cohorts (AUROC 0.710 and 0.701) with good calibration between observed and expected readmission events in both cohorts (p>.05). Unplanned readmission occurs less frequently in pediatric surgery than what is described in adults, calling into question its use as a quality indicator in this population. Factors that predict readmission including type of procedure, complications, and pLOS can be used to identify at-risk children and develop prevention strategies. III. Copyright © 2017 Elsevier Inc.

In the absence of definite guidelines in the area, we have carried a systemic review to provide a thorough overview concerning the efficacy and safety of recombinant activated factor VII (rFVIIa, NovoSeven®, Novo Nordisk A/S, Bagsværd, Denmark) in patients with Glanzmann's thrombasthenia (GT) and FVII deficiency, undergoing surgical procedures. PubMed, Web of Science, Scopus and EMBASE databases was employed for the search. Three multicenter registries were identified: the Glanzmann's Thrombasthenia Registry (GTR), the Seven Treatment Evaluation Registry (STER), and a German post-marketing surveillance registry (the WIRK study). In addition, data from 10 case-series and/or single-center experiences have been summarized. We have found that the following; perioperatively, the hemostatic effectiveness of rFVIIa was high in GT patients and in those with FVII deficiency undergoing both minor and major surgical procedures. Moreover, in all studies, rFVIIa was well tolerated. Thus, the current evidence shows an optimal perioperative safety/efficacy profile of rFVIIa in the setting of these rare bleeding disorders, and provides the rationale for further studies aimed at evaluating the optimal perioperative anti-hemorrhagic prophylaxis with rFVIIa in GT and in FVII deficient patients.

Simulation-based education has been shown to be an effective tool to teach foundational technical skills in various surgical specialties. However, most of the current simulations are limited to generic scenarios and do not allow continuation of the learning curve beyond basic technical skills to prepare for more advanced expertise, such as patient-specific surgical planning. The objective of this study was to evaluate the current medical literature with respect to the utilization and educational value of patient-specific simulations for surgical training. We performed a systematic review of the literature using Pubmed, Embase, and Scopus focusing on themes of simulation, patient-specific, surgical procedure, and education. The study included randomized controlled trials, cohort studies, and case-control studies published between 2005 and 2016. Two independent reviewers (W.H.R. and N.D) conducted the study appraisal, data abstraction, and quality assessment of the studies. The search identified 13 studies that met the inclusion criteria; 7 studies employed computer simulations and 6 studies used 3-dimensional (3D) synthetic models. A number of surgical specialties evaluated patient-specific simulation, including neurosurgery, vascular surgery, orthopedic surgery, and interventional radiology. However, most studies were small in size and primarily aimed at feasibility assessments and early validation. Early evidence has shown feasibility and utility of patient-specific simulation for surgical education. With further development of this technology, simulation-based education may be able to support training of higher-level competencies outside the clinical settingto aid learners in their development of surgical skills.

Patients treated with antithrombotic therapy that require abdominal surgical procedures has progressively increased overtime. The management of antithrombotics during both the peri- and post- operative period is of crucial importance. The goal of this review is to present current data concerning the management of antiplatelets in patients with coronary artery disease and of anticoagulants in patients with atrial fibrillation who had to undergo abdominal surgical operations. For this purpose, incidence of major adverse cardiovascular events (MACE) and risk of antithrombotic use during surgical procedures, as well as the recommendations based on recent guidelines were reported. A thorough search of PubMed, Scopus and the Cochrane Databases was conducted to identify randomized controlled trials, observational studies, novel current reviews, and ESC and ACC/AHA guidelines on the subject. Antithrombotic use in daily clinical practice results to two different pathways: reduction of thromboembolic risk, but a simultaneous increase of bleeding risk. This may cause a therapeutic dilemma during the perioperative period. Nevertheless, careless cessation of antithrombotics can increase MACE and thromboembolic events, however, maintenance of antithrombotic therapy may increase bleeding complications. Studies and current guidelines can assist clinicians in making decisions for the treatment of patients that undergo abdominal surgical operations while on antithrombotic therapy. Aspirin should not be stopped perioperatively in the majority of surgical operations. Determining whether to discontinue the use of anticoagulants before surgery depends on the surgical procedure. In surgical operations with a low risk for bleeding, oral anticoagulants should not be discontinued. Bridging therapy should only be considered in patients with a high risk of thromboembolism. Finally, patients with an intermediate risk for thromboembolism, management should be individualized according to patient

Venous thromboembolism (VTE) in pediatric surgical patients is a rare event. The risk factors for VTE in pediatric general surgery patients undergoing abdominopelvic procedures are unknown. The American College of Surgeon's National Surgical Quality Improvement Program-Pediatric (NSQIP-P) database (2012-2015) was queried for patients with VTE after abdominopelvic general surgery procedures. Patient and operative variables were assessed to identify risk factors associated with VTE and develop a pediatric risk score. From 2012-2015, 68 of 34,813 (0.20%) patients who underwent abdominopelvic general surgery procedures were diagnosed with VTE. On multivariate analysis, there was no increased risk of VTE based on concomitant malignancy, chemotherapy, inflammatory bowel disease, or laparoscopic surgical approach, while a higher rate of VTE was identified among female patients. The odds of experiencing VTE were increased on stepwise regression for patients older than 15 years and those with preexisting renal failure or a diagnosis of septic shock, patients with American Society of Anesthesia (ASA) classification ≥ 2, and for anesthesia time longer than 2 h. The combination of age > 15 years, ASA classification ≥ 2, anesthesia time > 2 h, renal failure, and septic shock was included in a model for predicting risk of VTE (AUC = 0.907, sensitivity 84.4%, specificity 88.2%). VTE is rare in pediatric patients, but prediction modeling may help identify those patients at heightened risk. Additional studies are needed to validate the factors identified in this study in a risk assessment model as well as to assess the efficacy and cost-effectiveness of prophylaxis methods.

This report addresses the problems related to surgical treatment of post-infarction ventricular tachycardia (VT) and is based on a 5 year experience of 36 consecutive patients. In every case the arrhythmia was unresponsive to pharmacological therapy. All patients were operated on after the completion of a diagnostic protocol including preoperative endocardial, intra-operative epi-endocardial mapping, the latter performed automatically when possible. Surgical techniques were: classical Guiraudon's encircling endocardial ventriculotomy (EEV); partial EEV, endocardial resection (ER); cryoablation or a combination of these procedures. The in-hospital mortality (30 days) was 8.3% (3 patients). During the follow-up period (1-68 months), 3 patients (9%) died of cardiac but not VT related causes. Of the survivors, 92% are VT-free. We consider electrophysiologically guided surgery a safe and reliable method for the treatment of post-infarction VT and suggest its more extensive use. We stress the importance of automatic mapping in pleomorphic and non-sustained VT, and the necessity of tailoring the surgical technique to the characteristics of each case.

What is the source of inadequate performance in the operating room? Is it a lack of technical skills, poor judgment or a lack of procedural knowledge? We created a surgical procedural knowledge (SPK) assessment tool and evaluated its use. We interviewed medical students, residents and training program staff on SPK assessment tools developed for 3 different common general surgery procedures: inguinal hernia repair with mesh in men, laparoscopic cholecystectomy and right hemicolectomy. The tools were developed as a step-wise assessment of specific surgical procedures based on techniques described in a current surgical text. We compared novice (medical student to postgraduate year [PGY]-2) and expert group (PGY-3 to program staff) scores using the Mann-Whitney U test. We calculated the total SPK score and defined a cut-off score using receiver operating characteristic analysis. In all, 5 participants in 7 different training groups (n = 35) underwent an interview. Median scores for each procedure and overall SPK scores increased with experience. The median SPK for novices was 54.9 (95% confidence interval [CI] 21.6-58.8) compared with 98.05 (95% CP 94.1-100.0) for experts (p = 0.012). The SPK cut-off score of 93.1 discriminates between novice and expert surgeons. Surgical procedural knowledge can reliably be assessed using our SPK assessment tool. It can discriminate between novice and expert surgeons for common general surgical procedures. Future studies are planned to evaluate its use for more complex procedures.

The association of operative duration with the risk of venous thromboembolism (VTE) has not been quantified in neurosurgery. To investigate the association of surgical duration for several neurosurgical procedures and the incidence of VTE. We performed a retrospective cohort study involving patients who underwent neurosurgical procedures from 2005 to 2012 and were registered in the American College of Surgeons National Quality Improvement Project registry. In order to control for confounding, we used multivariable regression models, and propensity score conditioning. During the study period, there were 94 747 patients, who underwent neurosurgical procedures, and met the inclusion criteria. Of these, 1358 (1.0%) developed VTE within 30 days postoperatively. Multivariable logistic regression demonstrated an association of longer operative duration with higher 30-day incidence of VTE (odds ratio [OR], 1.22; 95% confidence interval [CI], 1.19-1.25). Compared with procedures of moderate duration (third quintile, 40-60th percentile), patients undergoing the longest procedures (>80th percentile) had higher odds (OR, 3.15; 95% CI, 2.49-3.99) of developing VTE. The shortest procedures (<20th percentile) were associated with a decreased incidence of VTE (OR, 0.51; 95% CI, 0.27-0.76) in comparison to those of moderate duration. The same associations were present in propensity score-adjusted models, and models stratified by subgroups of cranial, spinal, peripheral nerve, and carotid procedures. In a cohort of patients from a national prospective surgical registry, increased operative duration was associated with increased incidence of VTE for neurosurgical procedures. These results can be used by neurosurgeons to inform operative management, and to stratify patients with regard to VTE risk. Copyright © 2016 by the Congress of Neurological Surgeons

This study defined the incidence and trends of surgeries performed for patients with cervical disc degeneration with and without tobacco use disorder (TUD). This study utilized the Humana Inc. database between 2007 and 2013 to identify patients with cervical disc degeneration with or without myelopathy. International Classification of Diseases, ninth revision (ICD-9) and Current Procedural Terminology (CPT) codes determined the initial diagnosis of disc degeneration, myelopathy status and TUD, whether patients received surgery, and TUD status at surgery. The prevalence of disc degeneration with myelopathy increased by 32.8% between 2007 and 2013, while disc disease with myelopathy and TUD increased by 91.6%. For patients without myelopathy, the prevalence of disc degeneration alone increased by 65.4%, and disc degeneration with myelopathy increased by 148.7%. Of myelopathy patients, 1717 (6.4%) had TUD and 1024 (59.6%) received surgery, compared to 6508 patients without TUD (26.1%). For patients without myelopathy, 11,337 (3.5%) had TUD and 787 (6.9%) underwent surgery, compared to 9716 patients (3%) without TUD. Of surgical patients, 781 (76.3%) with myelopathy and TUD still had a TUD diagnosis at surgery, and 542 (68.9%) of patients without myelopathy still had a TUD diagnosis at surgery. The prevalence of degenerative disc disease and TUD has increased more than disc disease alone. Patients with TUD were more likely to get surgery, and to have surgeries earlier than patients without TUD. Patients with TUD at the time of the diagnosis of their disc degeneration likely still had a TUD diagnosis at the time of surgery.

Full Text Available Background: Paediatric patients often present with different painful conditions that require immediate surgical interventions. Despite a plethora of articles on the ketamine-propofol combination, comprehensive evidence regarding the suitable sedoanalgesia regime is lacking due to heterogeneity in study designs. Methods: This prospective, randomized, double-blind, active-controlled trial was conducted in 100 children, of age 3-14 years, American Society of Anesthesiologist physical status IE-IIE, posted for emergency short surgical procedures. Patients were randomly allocated to receive either 2 mL of normal saline (pre-induction plus calculated volume of drug from the 11 mL of ketamine-propofol solution for induction (group PK, n=50 or fentanyl 1.5 μg/kg diluted to 2 mL with normal saline (pre-induction plus calculated volume of drug from the 11 mL of propofol solution for induction (group PF, n=50. In both the groups, the initial bolus propofol 1 mg/kg i.v. (assuming the syringes contained only propofol, for simplicity was followed by adjusted infusion to achieve a Ramsay Sedation Scale score of six. Mean arterial pressure (MAP was the primary outcome measurement. Results: Data from 48 patients in group PK and 44 patients in group PF were available for analysis. Hypotension was found in seven patients (14.6% in group PK compared with 17 (38.6% patients in group PF (P=0.009. Intraoperative MAP was significantly lower in group PF than group PK when compared with baseline. Conclusion: The combination of low-dose ketamine and propofol is more effective and a safer sedoanalgesia regimen than the propofol-fentanyl combination in paediatric emergency short surgical procedures in terms of haemodynamic stability and lesser incidence of apnoea.

We report a case of an indwelling inferior vena cava filter that penetrated the IVC wall after Whipple's pancreatico-duodenectomy procedure performed in a patient with ampullary carcinoma, resulting in right ureteral injury and obstruction with subsequent hydroureter and hydronephrosis. This was incidentally discovered on a computed tomography scan performed as routine follow up to evaluate the results of the surgery. We retrieved the inferior vena cava filter and placed a nephrostomy catheter to relieve the ureteral obstruction. Our case highlights the importance of careful inferior vena cava manipulation during abdominal surgery in the presence of an inferior vena cava filter, and the option of temporary removal of the filter to be placed again after surgery in order to avoid this complication, unless protection is required against clot migration during the surgical procedure.

Secondary hyperparathyroidism in elderly fragile patients presents clinical difficulties due to severity of symptoms and related comorbidity. The optimal surgical approach for this group of patients is still debated. The aim of the study was to define the optimal technique of parathyroidectomy in elderly patients with secondary hyperparathyroidism. Retrospective analysis in a series of 253 patients including 35 elderly individuals at a single institution was carried out. Postoperative parathyroid hormone decrease, surgical complications and symptoms control were analyzed for all patients in relation to the types of parathyroidectomy performed. In elderly patients, total parathyroidectomy was the most used approach. Subtotal parathyroidectomy was mostly reserved for younger patients suitable for kidney transplantation. No elderly patients treated with total parathyroidectomy were autotransplanted. No significant difference in surgical complications was observed between younger and elderly patients and considering the different procedures. Adequate symptom control after surgery was achieved in almost 90% of patients. A limited rate of recurrence requiring repeat surgery was observed only after subtotal parathyroidectomy. Considering the features of all types of parathyroidectomy, very low recurrence rate, contained postoperative hypocalcemia and limited complications following total parathyroidectomy, might represent specific advantages for elderly patients. Total parathyroidectomy without parathyroid transplantation is safe for elderly patients with secondary hyperparathyroidism and a good alternative to the well-established total parathyroidectomy with autografting.

To analyze the costs associated with two surgical procedures for lower urinary tract symptoms secondary to benign prostatic hyperplasia: GreenLight XPS 180¦W versus the gold standard transurethral resection of the prostate. A multicenter, retrospective cost study was carried out from the National Health Service perspective, over a 3-month time period. Costs were broken down into pre-surgical, surgical and post-surgical phases. Data were extracted from records of patients operated sequentially, with IPSS=15, Qmax=15 mL/seg and a prostate volume of 40-80mL, adding only direct healthcare costs (€, 2013) associated with the procedure and management of complications. A total of 79 patients sequentially underwent GL XPS (n: 39) or TURP (n: 40) between July and October, 2013. Clinical outcomes were similar (94.9% and 92.5%, GL XPS and TURP, respectively) without significant differences (P=.67). The average direct cost per patient was reduced by €114 in GL XPS versus TURP patients; the cost was higher in the surgical phase with GL XPS (difference: €1,209; P<.001) but was lower in the post-surgical phase (difference: €-1,351; P<.001). The GreenLight XPS 180-W laser system is associated with a reduction in costs with respect to transurethral resection of prostate in the surgical treatment of LUTS secondary to PBH. This reduction is due to a shorter inpatient length of stay that offsets the cost of the new technology. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

A medical platform for simulation of surgical procedures.

2001-01-01

Surgery simulation is a promising technique for training of surgical procedures. The overall goal for any surgical simulator is to allow for efficient training of the skills required and to improve learning by giving the user proper feedback. This goal is easier achieved if the training is performed in a realistic environment. Therefore functionality such as soft tissue deformation, tearing and cutting, penetration of soft tissue etc. is necessary. Furthermore, a realistic simulator must provide haptic feedback so that all senses match, that is, there should be a correspondence between what you see and what you feel with your hands. In this paper we describe a medical platform that provides all this functionality. It is based on the Reachln Magma API, which has been extended for surgery simulation. We describe the development of the platform and illustrate the use of it for the development of two different types of surgical simulators, both of which represents work in progress.

Full Text Available New mesh-related complications such as erosion, etc., can result from abnormal postoperative healing due to surgical site infection. The aim of our study was to compare systemic inflammatory responses and the incidence of early infectious complications after reconstructive surgery using synthetic mesh and after traditional vaginal wall repair. In this prospective observational study 99 women with symptomatic pelvic organ prolapse were included; 55 women underwent traditional repair and 44 repair using mesh. After the procedure infectious complications were monitored. The patients who underwent reconstructive surgery using mesh material were more likely to have febrile morbidity in the postoperative period than the patients who had been treated with traditional repair (p=0.031; there was a higher incidence of combination febrile morbidity with elevated C-reactive protein (CRP > 50 mg/l; p=0.046, and a higher incidence of CRP increase over 30 mg/l; p=0.005. Reconstructive procedures using synthetic mesh are accompanied by a higher incidence of early post-operative infectious complications.

Objective: To compare the influence of postoperative pelvic floor function after different surgical procedures of hysterectomy. Methods: A total of 260 patients who underwent hysterectomy in Renmin hospital of Wuhan University from January 2012 to January 2014 were enrolled in the study, and divided into 5 groups by different surgical procedures, which were total abdominal hysterectomy (A-TH; 46 cases), total laparoscopic hysterectomy (L-TH; 59 cases), total vaginal hysterectomy (V-TH; 42 cases), abdominal intrafascial hysterectomy (A-CISH; 78 cases), laparoscopic intrafascial hysterectomy (L-CISH; 35 cases). Pelvic examination, pelvic organ prolapse quantitation (POP-Q), test of pelvic muscle strength, pelvic floor distress inventory-short form 20 (PFDI-20) and the female sexual function index (FSFI) questionnaire were measured after 6 months and 12 months. Results: The differences of pelvic organ prolapse incidence after 6 months, A-TH and A-CISH [7% (3/46) versus 3% (2/78)], A-TH and L-CISH [7% (3/46) versus 3% (1/35)] were statistically significance (all P CISH was statistically different in degree ( P CISH [59% (27/46) versus 29% (23/78)], A-TH and L-CISH [59% (27/46) versus 26% (9/35)] were statistically significant (all P CISH [61% (36/59) versus 29%(23/78)] was statistically different ( P CISH [53% (31/59) verus 24% (19/78)], V-TH and A-CISH [60% (25/42) verus 24% (19/78)], V-TH and L-CISH [60% (25/42) verus 23% (8/35)] were statistically significant (all P CISH [57% (24/42) versus 26%(20/78)] was statistically significant ( P 0.05), PFDI-20 total score was not statistically significant ( P >0.05). FSFI total score after 6 months and 12 months in A-TH and A-CISH, L-TH and A-CISH, A-CISH and L-CISH were statistically significant (all P <0.05). Conclusion: The influences of different surgical procedures to pelvic floor function are no statistical difference; as to the surgical resection of hysterectomy, intrafascia hysterectomy compared with extrafascia

OBJECTIVE: To evaluate the effect of modifying perioperative care in noncardiac surgical patients on morbidity, mortality, and other outcome measures. BACKGROUND: New approaches in pain control, introduction of techniques that reduce the perioperative stress response, and the more frequent use...... anesthesia in elective operations, and pilot studies of fast track surgical procedures using the multimodality approach. RESULTS: The introduction of newer approaches to perioperative care has reduced both morbidity and mortality in surgical patients. In the future, most elective operations will become day...... surgical procedures or require only 1 to 2 days of postoperative hospitalization. Reorganization of the perioperative team (anesthesiologists, surgeons, nurses, and physical therapists) will be essential to achieve successful fast track surgical programs. CONCLUSIONS: Understanding perioperative...

We are evaluating the technical feasibility of robotic-assisted laparoscopic vertical-intermediate platysmaplasty in conjunction with an open rhytidectomy. In a cadaveric study, the da Vinci Surgical System was used to access certain angles in the lower neck that are difficult for traditional short incision, short flap procedures. Ergonomics, approach, and technical challenges were noted. To date, there are no published reports of robotic-assisted neck lifts, motivating us to assess its potential in this field of plastic surgery. Standard open technique short flap rhytidectomies with concurrent experimental robotic-assisted platysmaplasties (neck lifts) were performed on six cadavers with the da Vinci Si Surgical System(®) (Intuitive Surgical, Sunnyvale, CA, USA). The surgical procedures were performed on a diverse cadaver population from June 2011 to January 2012. The procedures included (1) submental incision and laser-assisted liposuction, (2) open rhytidectomy, and (3) robotic-assisted platysmaplasty using knot-free sutures. A variety of sutures and fat extraction techniques, coupled with 0° and 30° three-dimensional endoscopes, were utilized to optimize visualization of the platysma. An unaltered da Vinci Si Surgical System with currently available instruments was easily adaptable to neck lift surgery. Mid-neck platysma exposure was excellent, tissue handling was delicate and precise, and suturing was easily performed. Robotic-assisted surgery has the potential to improve outcomes in neck lifts by offering the ability to manipulate instruments with increased freedom of movement, scaled motion, tremor reduction, and stereoscopic three-dimensional visualization in the deep neck. Future clinical studies on live human patients can better assess subject and surgeon benefits arising from the use of the da Vinci system for neck lifts. Evidence obtained from multiple time series with or without the intervention, such as case studies. Dramatic results in

There is increased tendency towards double-gloving by general surgeons in our practice, due probably to awareness of the risk of contamination with blood or other body fluids during surgery. The aim of the study was to compare the relative frequency of glove puncture in single-glove versus double glove sets in general surgical procedures, and to determine if duration of surgery affects perforation rate. Surgeons at random do single or double gloves at their discretion, for general surgical procedures. All the gloves used by the surgeons were assessed immediately after surgery for perforation. A total of 1120 gloves were tested, of which 880 were double-glove sets and 240 single-glove sets. There was no significant difference in the overall perforation rate between single and double glove sets (18.3% versus 20%). However, only 2.3% had perforations in both the outer and inner gloves in the double glove group. Therefore, there was significantly greater risk for blood-skin exposure in the single glove sets (p < 0.01). The perforation rate was also significantly greater during procedures lasting an hour or more compared to those lasting less than an hour (p < 0.01). Double-gloving reduces the risk of blood-skin contamination in all general surgical procedures, and especially so in procedures lasting an hour or more.

Post-operative infection impacts the quality of patient care, prolongs the length of hospital stay, and utilizes more health care resources. The purpose of this study was to compare the rates of surgical site infection among three major surgical procedures for treating patients with colon pathology. The location of colon resection impacts the post-operative infection rate. A retrospective cohort study was conducted by using the 2006 Nationwide Inpatient Sample. Adult patients (age ≥18 yr) with colon diseases are the population of interest. The disease status and procedures were categorized according to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). Patients with a primary diagnosis of diverticulosis of the colon without hemorrhage (ICD-9-CM codes: 562.11 and 562.12) or malignant neoplasm of the colon (ICD-9-CM codes: 153.x, where x represents the possible digits within this ICD-9-CM code category), with procedures of open and other right hemicolectomy (ORH; ICD-9-CM code: 45.73) or open and other left hemicolectomy (OLH; ICD-9-CM code: 45.75), or open and other sigmoidectomy (OS; ICD-9-CM code: 45.76) were included for this study. The primary measured outcome for the study was surgical site infection. There were an estimated 26,381 ORH procedures, 9,558 OLH procedures, and 31,656 OS procedures performed in 2006. There was a significant difference among procedures with respect to their age distributions (mean [standard error]: ORH vs. OLH vs. OS=70.5 [0.2] vs. 63.8 [0.3] vs. 59.5 [0.2] yr, pinfection rates: ORH vs. OLH vs. OS=2.9% vs. 5.6% vs. 4.9%, pinfection for OLH (AOR [95% CI]: 1.31 [1.04-1.64], p=0.02) compared with OS. Different sites of colon operations were associated with different risks of surgical site infections. Accordingly, appropriate pre-operative measures should address these differences.

The basic necessities for surgical procedures are illumination, exposure, and magnification. These have undergone transformation in par with technology. One of the recent developments is the compact magnifying exoscope system. In this report, we describe the application of this system for surgical operations and discuss its advantages and pitfalls. We used the ViTOM exoscope mounted on the mechanical holding arm. The following surgical procedures were conducted: lumbar and cervical spinal canal decompression (n = 5); laminotomy and removal of lumbar migrated disk herniations (n = 4); anterior cervical diskectomy and fusion (n = 1); removal of intraneural schwannomas (n = 2); removal of an acute cerebellar hemorrhage (n = 1); removal of a parafalcine atypical cerebral hematoma caused by a dural arteriovenous fistula (n = 1); and microsutures and anastomoses of a nerve (n = 1), an artery (n = 1), and veins (n = 2). The exoscope offered excellent, magnified, and brilliantly illuminated high-definition images of the surgical field. All surgical operations were successfully completed. The main disadvantage was the adjustment and refocusing using the mechanical holding arm. The time required for the surgical operation under the exoscope was slightly longer than the times required for a similar procedure performed using an operating microscope. The magnifying exoscope is an effective and nonbulky tool for surgical procedures. In visualization around the corners, the exoscope has better potential than a microscope. With technical and technologic modifications, the exoscope might become the next generation in illumination, visualization, exposure, and magnification for high-precision surgical procedures.

Diagnostic screening for Anderson-Fabry cardiomyopathy (AFC) is performed in the presence of specific clinical red flags in patients with hypertrophic cardiomyopathy (HCM) older than 25 years. However, left ventricular outflow tract obstruction (LVOTO) has been traditionally considered an exclusion criteria for AFC. To examine a series of patients diagnosed with HCM and severe basal LVOTO undergoing myectomy in whom the diagnosis of AFC was suspected by the cardiac surgeon intraoperatively and confirmed by histological and genetic examinations. This retrospective analysis of patients undergoing surgical septal reduction strategies was conducted in 3 European tertiary referral centers for HCM from July 2013 to December 2016. Patients with a clinical diagnosis of obstructive HCM referred for surgical management of LVOTO were observed for at least 18 months after the procedure (mean [SD] follow-up, 33 [14] months). Etiology of patients with HCM who underwent surgical myectomy. From 2013, 235 consecutive patients with a clinical diagnosis of HCM underwent septal myectomy. The cardiac surgeon suspected a storage disease in 3 patients (1.3%) while inspecting their heart samples extracted from myectomy. The mean (SD) age at diagnosis for these 3 patients was 42 (4) years; all were male. None of the 3 patients presented with extracardiac features suggestive of AFC. All patients showed asymmetrical left ventricular hypertrophy, with maximal left ventricular thickness in the basal septum (19-31 mm), severe basal LVOTO (70-120 mm Hg), and left atrial dilatation (44-57 mm). Only 1 patient presented with late gadolinium enhancement on cardiovascular magnetic resonance at the right ventricle insertion site. The mean (SD) age at surgical procedure was 63 (5) years. On tactile sensation, the surgeon felt a spongy consistency of the surgical samples, different from the usual stony-elastic consistency typical of classic HCM, and this prompted histological examinations.

The purpose of the current study was to comprehensively evaluate occupational radiation exposure to all intraoperative and perioperative personnel involved in radioguided surgical procedures utilizing 18 F-fluorodeoxyglucose ( 18 F-FDG). Radiation exposure to surgeon, anesthetist, scrub technologist, circulating nurse, preoperative nurse, and postoperative nurse, using aluminum oxide dosimeters read by optically stimulated luminescence technology, was evaluated during ten actual radioguided surgical procedures involving administration of 18 F-FDG. Mean patient dosage of 18 F-FDG was 699 ± 181 MBq (range 451-984). Mean time from 18 F-FDG injection to initial exposure of personnel to the patient was shortest for the preoperative nurse (75 ± 63 min, range 0-182) followed by the circulating nurse, anesthetist, scrub technologist, surgeon, and postoperative nurse. Mean total time of exposure of the personnel to the patient was longest for the anesthetist (250 ± 128 min, range 69-492) followed by the circulating nurse, scrub technologist, surgeon, postoperative nurse, and preoperative nurse. Largest deep dose equivalent per case was received by the surgeon (164 ± 135 μSv, range 10-580) followed by the anesthetist, scrub technologist, postoperative nurse, circulating nurse, and preoperative nurse. Largest deep dose equivalent per hour of exposure was received by the preoperative nurse (83 ± 134 μSv/h, range 0-400) followed by the surgeon, anesthetist, postoperative nurse, scrub technologist, and circulating nurse. On a per case basis, occupational radiation exposure to intraoperative and perioperative personnel involved in 18 F-FDG radioguided surgical procedures is relatively small. Development of guidelines for monitoring occupational radiation exposure in 18 F-FDG cases will provide reassurance and afford a safe work environment for such personnel. (orig.)

Full Text Available Tracey L Stierer,1,2 Nancy A Collop3,41Department of Anesthesiology, 2Department of Critical Care Medicine, Otolaryngology Head and Neck Surgery, Johns Hopkins Medicine, Baltimore, MD, USA; 3Department of Medicine, 4Department of Neurology, Emory University, Emory Sleep Center, Wesley Woods Center, Atlanta, GA, USAAbstract: With recent advances in surgical and anesthetic technique, there has been a growing emphasis on the delivery of care to patients undergoing ambulatory procedures of increasing complexity. Appropriate patient selection and meticulous preparation are vital to the provision of a safe, quality perioperative experience. It is not unusual for patients with complex medical histories and substantial systemic disease to be scheduled for discharge on the same day as their surgical procedure. The trend to “push the envelope” by triaging progressively sicker patients to ambulatory surgical facilities has resulted in a number of challenges for the anesthesia provider who will assume their care. It is well known that certain patient diseases are associated with increased perioperative risk. It is therefore important to define clinical factors that warrant more extensive testing of the patient and medical conditions that present a prohibitive risk for an adverse outcome. The preoperative assessment is an opportunity for the anesthesia provider to determine the status and stability of the patient’s health, provide preoperative education and instructions, and offer support and reassurance to the patient and the patient’s family members. Communication between the surgeon/proceduralist and the anesthesia provider is critical in achieving optimal outcome. A multifaceted approach is required when considering whether a specific patient will be best served having their procedure on an outpatient basis. Not only should the patient's comorbidities be stable and optimized, but details regarding the planned procedure and the resources available

Age is considered as a risk factor in bariatric surgery. The observation was made on the basis of results from studies where patients underwent different type of surgery, but laparoscopic sleeve gastrectomy (LSG) was not among them. It is necessary to reevaluate the association of age with adverse events in the group of patients after LSG. To investigate the association of age with surgery-related adverse events in patients after LSG. Retrospective analysis of medical data was performed. The study involved 345 patients who underwent LSG in our institution between January 2013 and December 2014. The patients were subdivided by age into four groups according to quartiles. In 30-day follow-up adverse events were evaluated. We considered the presence of the following events as the endpoint of our study: death, medical events and surgical events. In general, we observed adverse events in 36 (10.4%) patients. The mortality rate in our study was 0.59%. Nineteen events were surgical and 18 medical. In 1 patient a surgical event was associated with a medical event. Bleeding was the most common surgical event and was observed in 17 (4.9%) cases. Age was not associated with surgical events (OR = 1.032, 95% CI: 0.991-1.075, p = 0.33) or medical events (OR = 0.997, 95% CI: 0.956-1.039, p = 0.89). The LSG is a safe bariatric procedure with low mortality. Bleeding is the most frequent surgical complication. Our findings suggest that age is not associated with increased risk of surgical or medical adverse events after LSG.

We retrospectively evaluated the diagnostic value of (18)F-2-fluorodeoxy-d-glucose positron emission tomography (FDG-PET) with statistical analysis for the foci detection and predictive utility for postsurgical seizure outcome of patients with mesial temporal lobe epilepsy (mTLE). We evaluated 40 patients who were diagnosed mTLE and underwent selective amygdalohippocampectomy (SAH) or anterior temporal lobectomy (ATL) in our institute. Preoperative interictal FDG-PET with statistical analysis using three-dimensional stereotactic surface projection (3D-SSP) was detected with several clinical data including seizure semiology, MRI, scalp electroencephalography, surgical procedure with SAH or ATL and postsurgical outcome. The region of interest (ROI) was defined on 'Hippocampus & Amygdala', 'Parahippocampal gyrus & Uncus', 'T1 & T2', and 'T3 & Fusiform gyrus'. We obtained the ratio of hypometabolism difference (RHD) by 3D-SSP, and evaluated the relation among hypometabolic extent, surgical outcome and surgical procedure. The RHD in each ROIs ipsilateral to operative side was significantly higher than that of contralateral side in good outcome group. Hypometabolism of 'Hippocampus & Amygdala' was most reliable prognostic factor. Patients of discordant with presurgical examinations hardly showed obvious lateralized hypometabolism. Nevertheless, when they have significantly high RHD in mesial temporal lobe, good surgical outcome was expected. There was not significant difference of RHD distribution between SAH and ATL in good outcome group. Significant hypometabolism in mesial temporal lobe on FDG-PET with 3D-SSP is useful to predict good surgical outcome for patients with mTLE, particularly in discordant patients with hypometabolism in mesial temporal structure. However, FDG-PET is not indicative of surgical procedure. Copyright © 2016 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

Rhabdomyolysis is a syndrome of injury of skeletal muscles associated with myoglobinuria, muscle weakness, electrolyte imbalance and often, acute kidney injury as severe complication. of this study is to detect the incidence of rhabdomyolysis in critically ill patients in the surgical intensive care unit (ICU), and to raise awareness of this medical condition and its treatment among the clinicians. A retrospective review of all surgical and trauma patients admitted to surgical ICU of the University Surgical Clinic "Mother Teresa" in Skopje, Macedonia, from January 1 st till December 31 st 2015 was performed. Patients medical records were screened for available serum creatine kinase (CK) with levels > 200 U/l, presence of myoglobin in the serum in levels > 80 ng/ml, or if they had a clinical diagnosis of rhabdomyolysis by an attending doctor. Descriptive statistical methods were used to analyze the collected data. Out of totally 1084 patients hospitalized in the ICU, 93 were diagnosed with rhabdomyolysis during the course of one year. 82(88%) patients were trauma patients, while 11(12%) were surgical non trauma patients. 7(7.5%) patients diagnosed with rhabdomyolysis developed acute kidney injury (AKI) that required dialysis. Average values of serum myoglobin levels were 230 ng/ml, with highest values of > 5000 ng/ml. Patients who developed AKI had serum myoglobin levels above 2000 ng/ml. Average values of serum CK levels were 400 U/l, with highest value of 21600 U/l. Patients who developed AKI had serum CK levels above 3000 U/l. Regular monitoring and early detection of elevated serum CK and myoglobin levels in critically ill surgical and trauma patients is recommended in order to recognize and treat rhabdomyolysis in timely manner and thus prevent development of AKI.

Patients with solid tumors frequently undergo surgical procedures and develop procedure-related infections. We sought to describe the current microbiologic spectrum of infections at various sites following common surgical procedures. This was a retrospective review of microbiologic data between January 2011 and February 2012. The sites studied were those associated with breast cancer surgery, thoracotomy, craniotomy, percutaneous endoscopic gastrostomy (PEG) tube insertion, and abdominal/pelvic surgery. Only patients with solid tumors were included. A total of 368 surgical site infections (SSIs) were identified (68 breast cancer related; 91 thoracotomy related; 45 craniotomy related; 75 PEG-tube insertion related; and 89 abdominal/pelvic surgery related). Of these, 58% were monomicrobial and 42% were polymicrobial. Overall, 85% of the 215 monomicrobial infections were caused by Gram-positive organisms and 13% by Gram-negative bacilli (GNB). Staphylococcus aureus was the predominant pathogen in monomicrobial infections (150 of 215, 70%). Sixty (40%) of these staphylococcal isolates were methicillin resistant (MRSA), and 65% had a vancomycin minimal inhibitory concentration (MIC) ≥1.0 µg/ml. Pseudomonas aeruginosa was the predominant GNB pathogen (19 of 27, 70%). Staphylococci were also the predominant pathogens in polymicrobial infections, while P. aeruginosa and Escherichia coli were the predominant GNB. Overall, 35% of isolates from polymicrobial infections were GNB. Cephalosporins (e.g., cefazolin) or amoxicillin/clavulanate was used most often for surgical prophylaxis, and 47% of organisms from monomicrobial infections (MRSA, P. aeruginosa) were resistant to them. A similar resistance pattern was observed in polymicrobial infections. Staphylococcus species were isolated most often from the sites studied. Polymicrobial infections (42%) and GNB monomicrobial infections (13%) were relatively frequent causes of SSIs. Many of these infections were caused by

Management of coagulation in neurosurgical procedures is challenging. In this contest, it is imperative to avoid further intracranial bleeding. Perioperative bleeding can be associated with a number of factors, including anticoagulant drugs and coagulation status but is also linked to the characteristic and the site of the intracranial disorder. The aim of this review will be to focus primarily on the new evidence regarding the management of coagulation in patients undergoing craniotomy for neurosurgical procedures. Antihemostatic and anticoagulant drugs have shown to be associated with perioperative bleeding. On the other hand, an increased risk of venous thromboembolism and hypercoagulative state after elective and emergency neurosurgery, in particular after brain tumor surgery, has been described in several patients. To balance the risk between thrombosis and bleeding, it is important to be familiar with the perioperative changes in coagulation and with the recent management guidelines for anticoagulated patients undergoing neurosurgical procedures, in particular for those taking new direct anticoagulants. We have considered the current clinical trials and literature regarding both safety and efficacy of deep venous thrombosis prophylaxis in the neurosurgical population. These were mainly trials concerning both elective surgical and intensive care patients with a poor grade intracranial bleed or multiple traumas with an associated severe traumatic brain injury (TBI). Coagulation management remains a major issue in patients undergoing neurosurgical procedures. However, in this field of research, literature quality is poor and further studies are necessary to identify the best strategies to minimize risks in this group of patients.

To evaluate perioperative red blood cell (RBC) ordering and interhospital variability patterns in pediatric patients undergoing surgical interventions at US children's hospitals. This is a multicenter cross-sectional study of children aged blood type and crossmatch were included when done on the day before or the day of the surgical procedure. The RBC transfusions included were those given on the day of or the day after surgery. The type and crossmatch-to-transfusion ratio (TCTR) was calculated for each surgical procedure. An adjusted model for interhospital variability was created to account for variation in patient population by age, sex, race/ethnicity, payer type, and presence/number of complex chronic conditions (CCCs) per patient. A total of 357 007 surgical interventions were identified across all participating hospitals. Blood type and crossmatch was performed 55 632 times, and 13 736 transfusions were provided, for a TCTR of 4:1. There was an association between increasing age and TCTR (R(2) = 0.43). Patients with multiple CCCs had lower TCTRs, with a stronger relationship (R(2) = 0.77). There was broad variability in adjusted TCTRs among hospitals (range, 2.5-25). The average TCTR in US children's hospitals was double that of adult surgical data, and was associated with wide interhospital variability. Age and the presence of CCCs markedly influenced this ratio. Studies to evaluate optimal preoperative RBC ordering and standardization of practices could potentially decrease unnecessary costs and wasted blood. Copyright © 2016 Elsevier Inc.

Fast-track surgery: A new concept of perioperative management of surgical patients

Directory of Open Access Journals (Sweden)

Gabriel Rodrigues

2013-01-01

Full Text Available In the past few decades, surgery has advanced greatly because of an improved understanding of perioperative pathophysiology, development of minimally invasive operative techniques and advanced anaesthetic techniques. Fewer operations are requiring extended periods of hospital stay and a growing number of procedures are performed on an ambulatory basis. The pressure on medical systems is continuously growing as a result of economic constraints, increasing numbers of patients undergoing surgical procedures and greater patient autonomy. Patient awareness is steadily increasing along with their participation in their own care, leading to expectations of a higher standard of care. This has led to the development of a new concept of fast-track surgery.

Guidelines on the facilities required for minor surgical procedures and minimal access interventions.

LENUS (Irish Health Repository)

Humphreys, H

2012-02-01

There have been many changes in healthcare provision in recent years, including the delivery of some surgical services in primary care or in day surgery centres, which were previously provided by acute hospitals. Developments in the fields of interventional radiology and cardiology have further expanded the range and complexity of procedures undertaken in these settings. In the face of these changes there is a need to define from an infection prevention and control perspective the basic physical requirements for facilities in which such surgical procedures may be carried out. Under the auspices of the Healthcare Infection Society, we have developed the following recommendations for those designing new facilities or upgrading existing facilities. These draw upon best practice, available evidence, other guidelines where appropriate, and expert consensus to provide sensible and feasible advice. An attempt is also made to define minimal access interventions and minor surgical procedures. For minimal access interventions, including interventional radiology, new facilities should be mechanically ventilated to achieve 15 air changes per hour but natural ventilation is satisfactory for minor procedures. All procedures should involve a checklist and operators should be appropriately trained. There is also a need for prospective surveillance to accurately determine the post-procedure infection rate. Finally, there is a requirement for appropriate applied research to develop the evidence base required to support subsequent iterations of this guidance.

Full Text Available Background Oncoplastic surgery is being increasingly performed in Korean women; however, unlike Westerners, Korean women usually have small to moderate-sized breasts. To achieve better outcomes in reconstructed breasts, several factors should be considered to determine the optimal surgical method. Methods A total of 108 patients who underwent oncoplastic surgery from January 2013 to December 2016 were retrospectively investigated. We used various methods, including glandular tissue reshaping, latissimus dorsi (LD flap transposition, and reduction oncoplasty, to restore the breast volume and symmetry. Results The mean weight of the tumor specimens was 40.46 g, and the ratio of the tumor specimen weight to breast volume was 0.12 g/mL in the patients who underwent glandular tissue reshaping (n=59. The corresponding values were 101.47 g and 0.14 g/mL, respectively, in the patients who underwent reduction oncoplasty (n=17, and 82.54 g and 0.20 g/mL, respectively, in those treated with an LD flap (n=32. Glandular tissue reshaping was mostly performed in the upper outer quadrant, and LD flap transposition was mostly performed in the lower inner quadrant. No major complications were noted. Most patients were satisfied with the aesthetic results. Conclusions We report satisfactory outcomes of oncoplastic surgical procedures in Korean patients. The results regarding specimen weight and the tumor-to-breast ratio of Asian patients will be a helpful reference point for determining the most appropriate oncoplastic surgical technique.

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.

Plantar fasciopathy presents with pain at the plantar and medial aspect of the heel. If chronic, it can negatively impact on quality of life. Plantar fasciopathy is not always self-limiting, and can be debilitating. Surgical management involves different procedures. We describe a percutaneous plantar fascia release. A minimally invasive access to the plantar tuberosity of the calcaneus is performed, and a small scalpel blade is used to release the fascia. With this procedure, skin healing problems, nerve injuries, infection and prolonged recovery time are minimised, allowing early return to normal activities. V.

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

Association between esophageal achalasia/ gastroesophageal reflux disease (GERD) and cholelithiasis is not clear. Epidemiological data are controversial due to different methodologies applied, the regional differences and the number of patients involved. Results of concomitant cholecistectomy associated to surgical treatment of both diseases regarding safety is poorly understood. To analyze the prevalence of cholelithiasis in patients with esophageal achalasia and gastroesophageal reflux submitted to cardiomyotomy or fundoplication. Also, to evaluate the safety of concomitant cholecistectomy. Retrospective analysis of 1410 patients operated from 2000 to 2013. They were divided into two groups: patients with GERD submitted to laparocopic hiatoplasty plus Nissen fundoplication and patients with esophageal achalasia to laparoscopic cardiomyotomy plus partial fundoplication. It was collected epidemiological data, specific diagnosis and subgroups, the presence or absence of gallstones, surgical procedure, operative and clinical complications and mortality. All groups/subgroups were compared. From 1,229 patients with GERD or esophageal achalasia, submitted to laparoscopic cardiomyotomy or fundoplication, 138 (11.43%) had cholelitiasis, occurring more in females (2.38:1) with mean age of 50,27 years old. In 604 patients with GERD, 79 (13,08%) had cholelitiasis. Lower prevalence occurred in Barrett's esophagus patients 7/105 (6.67%) (p=0.037). In 625 with esophageal achalasia, 59 (9.44%) had cholelitiasis, with no difference between chagasic and idiopathic forms (p=0.677). Complications of patients with or without cholecystectomy were similar in fundoplication and cardiomyotomy (p=0.78 and p=1.00).There was no mortality or complications related to cholecystectomy in this series. Prevalence of cholelithiasis was higher in patients submitted to fundoplication (GERD). Patients with chagasic or idiopatic forms of achalasia had the same prevalence of cholelithiasis. Gallstones

1992-08-01

Atrial tachycardia is an infrequent but potentially dangerous arrhythmia which often determines cardiac enlargement. Surgical ablation of the arrhythmia is effective and safe, provided a careful atrial mapping is performed and the surgical technique is tailored to the individual focus location. Eight patients underwent surgical ablation of ectopic atrial tachycardia between 1977 and 1990. Different techniques were adopted for each patient according to the anatomical location of the focus and possibly associated arrhythmias. Whenever possible, a closed heart procedure was chosen. In 1 patient a double focal origin was found and treated by separate procedures. In 1 patient with ostium secundum atrial septal defect and atrial flutter, surgical isolation of the right appendage and the ectopic focus was performed. In all patients ectopic atrial tachycardia was ablated with maintenance of the sinoatrial and atrioventricular nodal function as well as internodal conduction. In follow-up up to December 1991, no recurrency was recorded.

Introduction Surgical site infections pose a significant problem in the treatment of neurosurgical procedures, regardless of the application of perioperative prophylaxis with systemic antibiotics. The infection rate in these procedures ranges from less than 1% to above 15%. Different antibiotics and administration regimes have been used in the perioperative prophylaxis so far, and there are numerous comparative studies regarding their efficiency, however, it is generally indicated that the choice thereof should be based on information and local specifics connected to the most probable bacterial causers, which would possibly contaminate the surgical site and cause infection, and moreover, the mandatory compliance with the principles of providing adequate concentration of the drug at the time of the anticipated contamination. Objective Comparing the protective effect of two perioperative prophylactic antibiotic regimes using cefuroxime (second generation cephalosporin) and ceftriaxone (third generation cephalosporin) in the prevention of postoperative surgical site infections after elective and urgent cranial and spinal neurosurgical procedures at the University Clinic for Neurosurgery in Skopje in the period of the first three months of 2016. Design of the study Prospective randomized comparative study. Outcome measures Establishing the clinical outcome represented as prevalence of superficial and deep incision and organ/space postoperative surgical site infections. Material and method We analyzed prospectively 40 patients who received parenteral antibiotic prophylaxis with two antibiotic regimes one hour before the routine neurosurgical cranial and spinal surgical procedures; the patients were randomized in two groups, according to the order of admission and participation in the study, alternately, non-selectively, those persons who fulfilled inclusion criteria were placed in one of the two programmed regimes with cefuroxime in the first, and cefotaxime in the

Postoperative nausea and vomiting (PONV) affect approximately 80% of surgical patients and is associated with increased length of hospital stay and systemic costs. Preoperative and postoperative pain, anxiety and depression are also commonly reported. Recent evidence regarding their safety and effectiveness has not been synthesised. The aim of this systematic review is to evaluate the efficacy and safety of herbal medications for the treatment and prevention of anxiety, depression, pain and PONV in patients undergoing laparoscopic, obstetrical/gynaecological and cardiovascular surgical procedures. The following electronic databases will be searched up to 1 October 2016 without language or publication status restrictions: CENTRAL, MEDLINE, EMBASE, CINAHL, Web of Science and LILACS. Randomised clinical trials enrolling adult surgical patients undergoing laparoscopic, obstetrical/gynaecological and cardiovascular surgeries and managed with herbal medication versus a control group (placebo, no intervention or active control) prophylactically or therapeutically will be considered eligible. Outcomes of interest will include the following: anxiety, depression, pain, nausea and vomiting. A team of reviewers will complete title and abstract screening and full-text screening for identified hits independently and in duplicate. Data extraction, risk of bias assessments and evaluation of the overall quality of evidence for each relevant outcome reported will be conducted independently and in duplicate using the Grading of Recommendations Assessment Development and Evaluation classification system. Dichotomous data will be summarised as risk ratios; continuous data will be summarised as standard average differences with 95% CIs. This is one of the first efforts to systematically summarise existing evidence evaluating the use of herbal medications in laparoscopic, obstetrical/gynaecological and cardiovascular surgical patients. The findings of this review will be disseminated

Full Text Available Abstract Despite remarkable developments in the use of surgical techniques, ergonomic advancements in the operating room, and implementation of bundles, surgical site infections (SSIs remain a substantial burden, associated with increased morbidity, mortality and healthcare costs. National and international recommendations to prevent SSIs have been published, including recent guidelines by the World Health Organization, but implementation into clinical practice remains an unresolved issue. SSI improvement programs require an integrative approach with measures taken during the pre-, intra- and postoperative care from the numerous stakeholders involved. The current SSI prevention strategies have focused mainly on the role of healthcare workers (HCWs and procedure related risk factors. The importance and influence of patient participation is becoming an increasingly important concept and advocated as a means to improve patient safety. Novel interventions supporting an active participative role within SSI prevention programs have not been assessed. Empowering patients with information they require to engage in the process of SSI prevention could play a major role for the implementation of recommendations. Based on available scientific evidence, a panel of experts evaluated options for patient involvement in order to provide pragmatic recommendations for pre-, intra- and postoperative activities for the prevention of SSIs. Recommendations were based on existing guidelines and expert opinion. As a result, 9 recommendations for the surgical patient are presented here, including a practice brief in the form of a patient information leaflet. HCWs can use this information to educate patients and allow patient engagement.

We recently reported a grading system for surgical complications. This system proved to have a high sensitivity for recording minor but meaningful complications prolonging hospital stay in patients after colorectal surgery. We aimed to prospectively validate the complication grading system in a general surgery department over 1 year. All surgical procedures and related complications were prospectively recorded between January 1st and December 31st, 2009. Surgical complications were graded on a severity scale of 1-5. The system classifies short-term outcome by grade emphasizing intensity of therapy required for treatment of the defined complication. During the study period, 2114 patients underwent surgery. Elective and oncological surgeries were performed in 1606 (76%) and 465 (22%) patients, respectively. There were 422 surgical complications in 304 (14%) patients (Grade 1/2: 203 [67%]; Grade 3/4: 90 [29%]; Grade 5: 11 [4%]). Median length of stay correlated significantly with complication severity: 2.3 d for no complication, 6.2 and 11.8 d for Grades 1/2 and 3/4, respectively (P 2 (OR 2.07, P Grade (OR 1.85, P = 0.001), oncological (OR 2.82, P 120 min (OR 2.08, P grading surgical complications permits standardized reporting of surgical morbidity according to the severity of impact. Prospective validation of this system supports its use in a general surgery setting as a tool for surgical outcome assessment and quality assurance. Copyright © 2014 Elsevier Inc.

Antegrade continence enema (ACE) has become an important therapeutic modality in the treatment of intractable constipation and fecal incontinence. There are little data available on the long-term performance of the ACE procedure in children. A retrospective review of patients who underwent the ACE procedure was conducted. Irrigation characteristics and complications were noted. Outcome was assessed for individual encounters based on frequency of bowel movements, incontinence, pain, and predictability. One hundred seventeen patients underwent an ACE. One hundred five patients had at least 6 months of follow-up, and were included in the analysis. Diagnoses included myelodysplasia (39%), functional intractable constipation (26%), anorectal malformations (21%), nonrelaxing internal anal sphincter (7%), cerebral palsy (3%), and other diagnoses (4%). The average follow-up was 68 months (range 7-178 months). At the last follow-up, 69% of patients had successful bowel management. Of the 31% of patients who did not have successful bowel management, 20% were using the ACE despite suboptimal results, 10% required surgical removal, and 2% were not using the ACE because of behavioral opposition to it. Patients were started on normal saline, but were switched to GoLYTELY (PEG-3350 and electrolyte solution) if there was an inadequate response (61% at final encounter). Additives were needed in 34% of patients. The average irrigation dose was 23 ± 0.7 mL/kg. The average toilet sitting time was 51.7 ± 3.5 minutes, with infusions running for 12.1 ± 1.2 minutes. Stomal complications occurred in 63% (infection, leakage, and stenosis) of patients, 33% required surgical revision and 6% eventually required diverting ostomies. Long-term use of the ACE gives successful results in 69% of patients, whereas 63% had a stoma-related complication and 33% required surgical revision of the stoma.

Perioperative stroke is a devastating complication after cardiac surgery. In an attempt to minimize this complication, many cardiac surgeons routinely preoperatively order carotid artery duplex scans to assess for significant carotid stenosis. We hypothesize that the routine screening of preoperative cardiac surgery patients with carotid artery duplex scans detects few patients who would benefit from carotid intervention or that a significant carotid stenosis reliably predicts stroke risk after cardiac surgery. A retrospective review identified 1,499 patients who underwent cardiac surgical procedures between July 1999 and September 2010. Data collected included patient demographics, comorbidities, history of previous stroke, preoperative carotid artery duplex scan results, location of postoperative stroke, and details of carotid endarterectomy (CEA) procedures before, in conjunction with, or after cardiac surgery. Statistical methods included univariate analysis and Fisher's exact test. Twenty-six perioperative strokes were identified (1.7%). In the 21 postoperative stroke patients for whom there is complete carotid artery duplex scan data, 3 patients had a hemodynamically significant lesion (>70%) and 1 patient underwent unilateral carotid CEA for bilateral disease. Postoperative strokes occurred in the anterior cerebral circulation (69.2%), posterior cerebral circulation (15.4%), or both (15.4%). Patient comorbidities, preoperative carotid artery duplex scan screening velocities, or types of cardiac surgical procedure were not predictive for stroke. Thirteen patients (0.86%) underwent CEA before, in conjunction with, or after cardiac surgery. Two of these patients had symptomatic disease, 1 of whom underwent CEA before and the other after his cardiac surgery. Of the 11 asymptomatic patients, 2 underwent CEA before, 3 concurrently, and 6 after cardiac surgery. Left main disease (≥50% stenosis), previous stroke, and peripheral vascular disease were found to be

To evaluate the effect of local nitroglycerin on the viable area of a prefabricated flap for vascular implant in rats, and to investigate the surgical delay procedure. A femoral pedicle was implanted under the skin of the abdominal wall in forty Wistar rats. The animals were divided into four groups of ten: group 1 - without surgical delay procedure and local nitroglycerin; group 2 - with surgical delay procedure, but without local nitroglycerin; group 3 - without surgical delay procedure, but with local nitroglycerin; and group 4 - with simultaneous surgical delay procedure and local nitroglycerin. The percentages of the viable areas, in relation to the total flap, were calculated using AutoCAD R 14. The mean percentage value of the viable area was 8.9% in the group 1. 49.4% in the group 2; 8.4% in the group 3 and 1.1% in the group 4. There was significant difference between groups 1 and 2 (p=0.005), 1 and 4 (p=0.024), 2 and 3 (p=0.003), 2 and 4 (p=0.001). These results support the hypothesis that the closure of the arterial venous channels is responsible for the phenomenon of surgical delay procedure. Local nitroglycerin did not cause an increase in the prefabricated viable flap area by vascular implantation and decreased the viable flap area that underwent delay procedures.

Comparative outcomes of patients undergoing pericardiocentesis or pericardial window are limited. Development of pericardial effusion after cardiac surgery is common but no data exist to guide best management. Procedural billing codes and Cleveland Clinic surgical registries were used to identify 1,281 patients who underwent either pericardiocentesis or surgical pericardial window between January 2000 and December 2012. The 656 patients undergoing an intervention for a pericardial effusion secondary to cardiac surgery were also compared. Propensity scoring was used to identify well-matched patients in each group. In the overall cohort, in-hospital mortality was similar between the group undergoing pericardiocentesis and surgical drainage (5.3% vs 4.4%, p = 0.49). Similar outcomes were found in the propensity-matched group (4.9% vs 6.1%, p = 0.55). Re-accumulation was more common after pericardiocentesis (24% vs 10%, p <0.0001) and remained in the matched cohorts (23% vs 9%, p <0.0001). The secondary outcome of hemodynamic instability after the procedure was more common in the pericardial window group in both the unmatched (5.2% vs 2.9%, p = 0.036) and matched cohorts (6.1% vs 2.0%, p = 0.022). In the subgroup of patients with a pericardial effusion secondary to cardiac surgery, there was a lower mortality after pericardiocentesis in the unmatched group (1.5% vs 4.6%, p = 0.024); however, after adjustment, this difference in mortality was no longer present (2.6% vs 4.5%, p = 0.36). In conclusion, both pericardiocentesis and surgical pericardial window are safe and effective treatment strategies for the patient with a pericardial effusion. In our study there were no significant differences in mortality in patients undergoing either procedure. Observed differences in outcomes with regard to recurrence rates, hemodynamic instability, and in those with postcardiac surgery effusions may help to guide the clinician in management of the patient

Patient satisfaction: does surgical volume matter?

Tevis, Sarah E; Kennedy, Gregory D

2015-06-01

Patient satisfaction is an increasing area of interest due to implications of pay for performance and public reporting of results. Although scores are adjusted for patient factors, little is known about the relationship between hospital structure, postoperative outcomes, and patient satisfaction with the hospital experience. Hospitals participating in the University HealthSystem Consortium database from 2011-2012 were included. Patients were restricted to those discharged by general surgeons to isolate surgical patients. Hospital data were paired with Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) results from the Hospital Compare website. Postoperative outcomes were dichotomized based on the median for all hospitals and stratified based on surgical volume. The primary outcome of interest was high on overall patient satisfaction, whereas other HCAHPS domains were assessed as secondary outcomes. Chi square and binary logistic regression analyses were performed to evaluate whether postoperative outcomes or surgical volume more significantly influenced high patient satisfaction. The study population consisted of 171 hospitals from the University HealthSystem Consortium database. High surgical volume was a more important predictor of overall patient satisfaction regardless of hospital complication (P patient satisfaction on the HCAHPS survey than postoperative outcomes, whereas volume was less predictive in other HCAHPS domains. Patients may require more specific questioning to identify high quality, safe hospitals. Copyright © 2015 Elsevier Inc. All rights reserved.

2007-09-01

This article presents a review on the efficacy of surgical ventricular restoration and direct surgery for ventricular tachycardia in patients with left ventricular aneurysm or dilated ischemic cardiomyopathy. The procedure includes a non-electrophysiologically guided subtotal endocardiectomy and cryoablation in addition to endoventricular patch plasty of the left ventricle. Coronary artery bypass surgery and mitral valve repair are performed concomitantly as needed. In our experience, this procedure yielded a 90% success rate in terms of freedom from spontaneous ventricular tachycardia, with an early mortality rate of 3.8%. A practical guide to the pre- and postoperative management of these patients is provided.

Systemic sclerosis (scleroderma) is frequently associated with both gastroesophageal reflux disease (GERD) and simultaneous esophageal dysmotility. Anti-reflux procedures in this patient population must account for the existing physiology of each patient and likely disease progression. We aim to compare perioperative and intermediate outcomes of fundoplication versus gastric bypass for the treatment of GERD. After IRB approval, patients with systemic sclerosis undergoing fundoplication or gastric bypass for the treatment of GERD from 2004 to 2016 were identified. Demographics, perioperative data, immediate complications, and symptom improvement were retrieved and analyzed. Fourteen patients with systemic sclerosis underwent surgical treatment of GERD during the defined study period. Average body mass index was 26 kg/m 2 . Seven fundoplications (2 Nissens, 4 Toupets, and 1 Dor) and 7 Roux-en-Y gastric bypasses (RYGB) were performed. No 30-day mortality was observed in either group. Median follow-up was 97 months for the fundoplication group (range 28-204 months), and 19 months for the RYGB group (range 1-164 months). Preoperatively, dysphagia, heartburn, and regurgitation were present in 71% (n = 10), 86% (n = 12), and 64% (n = 9) of patients, respectively. Eleven patients had pH study prior to surgical intervention, and 91% of them had abnormal acid exposure. Esophagitis was evident in 85% (n = 11) of patients during preoperative upper endoscopy, and two patients had Barrett's esophagus. Impaired esophageal motility was present in all RYGB patients and 71% of fundoplication patients. Of the patients who had assessment of their GERD symptoms at follow-up, all five patients in the RYGB group and only 3 (50%) patients in the fundoplication group reported symptom improvement or resolution. Laparoscopic RYGB as an anti-reflux procedure is safe and may provide an alternative to fundoplication in the treatment of GERD for systemic sclerosis patients

Surgical therapy in chronic pancreatitis.

2012-12-01

Chronic pancreatitis (CP) is an inflammatory disease of the pancreas which causes chronic pain, as well as exocrine and endocrine failure in the majority of patients, together producing social and domestic upheaval and a very poor quality of life. At least half of patients will require surgical intervention at some stage in their disease, primarily for the treatment of persistent pain. Available data have now confirmed that surgical intervention may produce superior results to conservative and endoscopic treatment. Comprehensive individual patient assessment is crucial to optimal surgical management, however, in order to determine which morphological disease variant (large duct disease, distal stricture with focal disease, expanded head or small duct/minimal change disease) is present in the individual patient, as a wide and differing range of surgical approaches are possible depending upon the specific abnormality within the gland. This review comprehensively assesses the evidence for these differing approaches to surgical intervention in chronic pancreatitis. Surgical drainage procedures should be limited to a small number of patients with a dilated duct and no pancreatic head mass. Similarly, a small population presenting with a focal stricture and tail only disease may be successfully treated by distal pancreatectomy. Long-term results of both of these procedure types are poor, however. More impressive results have been yielded for the surgical treatment of the expanded head, for which a range of surgical options now exist. Evidence from level I studies and a recent meta-analysis suggests that duodenum-preserving resections offer benefits compared to pancreaticoduodenectomy, though the results of the ongoing, multicentre ChroPac trial are awaited to confirm this. Further data are also needed to determine which of the duodenum-preserving procedures provides optimal results. In relation to small duct/minimal change disease total pancreatectomy represents the only

Leucoscintigraphy with Tc-99m-HMPAO is an important diagnostic modality for localizing of the site of infection. It has distinct advantages over gallium 67 and indium-111 labelled leukocytes, in terms of better image quality, less cell activation and the choice of using Technetium instead of In-111. This study was designed to set up the technique in AEMC, Multan Pakistan, to assess the practicality of using the procedure, and to see if the results offered additional clinical information that could affect patient management in our clinical environment. 27 patients were studied using the technique. There were 17 post-surgical patients, 4 post-partal patients and 6 patients who did no fit into the above categories. An accuracy of 81%, sensitivity of 75% and a specificity of 100 % were achieved. The spectrum of clinical presentation was broad and included post-operative infections, intra-abdominal haematoms, brain abscesses, localized peritonitis, sterile and infected intraperitoneal collections, infected pleural effusions and pyrexia of unknown origin. It was concluded that this technique is practicable in our conditions and gives important clinical information. (author)

The aim of the study is to evaluate the therapeutic effect of a new surgical procedure, dumbbell-form resection (DFR), for hilar cholangiocarcinoma (HCCA) with severe jaundice. In DFR, liver segments I, IVb, and partial V above the right hepatic pedicle are resected.Hemihepatectomy is recognized as the preferred procedure; however, its application is limited in HCCAs with severe jaundice.Thirty-eight HCCA patients with severe jaundice receiving DFR and 70 receiving hemihepatectomy from January 2008 to January 2013 were included. Perioperative parameters, operation-related morbidity and mortality, and post-operative survival were analyzed.A total of 21.1% patients (8/38) in the DFR group received percutaneous transhepatic biliary drainage (PTBD), which was significantly jaundice. However, its indications should be restricted.

2017-03-01

Surgical emphysema is a rare complication of dental extractions, often associated with the use of high-speed air rotors. This report describes a case of extensive surgical emphysema following a simple surgical extraction of a LL6 under local anaesthetic. There was no use of air-driven handpieces during the procedure. The patient developed extensive surgical emphysema bi-laterally in both cervical neck and facial planes. After prophylactic antibiotics with careful monitoring in a secondary care setting, the patient made a full unremarkable recovery. Clinical relevance: Simple extraction of teeth is a procedure carried out daily by most general dental practitioners. However, the risk of surgical emphysema without the use of high-speed air rotors or instruments using pressurized air/water is not well known or documented.

Google Glass has the potential to become a ubiquitous and translational technological tool within clinical plastic surgery. Google Glass allows clinicians to remotely view patient notes, laboratory results, and imaging; training can be augmented via streamed expert master classes; and patient safety can be improved by remote advice from a senior colleague. This systematic review identified and appraised every Google Glass publication relevant to plastic surgery and describes the first plastic surgical procedures recorded using Google Glass. A systematic review was performed using PubMed National Center for Biotechnology Information, Ovid MEDLINE, and the Cochrane Central Register of Controlled Trials, following modified Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Key search terms "Google" and "Glass" identified mutually inclusive publications that were screened for inclusion. Eighty-two publications were identified, with 21 included for review. Google Glass publications were formal articles (n = 3), editorial/commentary articles (n = 7), conference proceedings (n = 1), news reports (n = 3), and online articles (n = 7). Data support Google Glass' positive impact on health care delivery, clinical training, medical documentation, and patient safety. Concerns exist regarding patient confidentiality, technical issues, and limited software. The first plastic surgical procedure performed using Google Glass was a blepharoplasty on October 29, 2013. Google Glass is an exciting translational technology with the potential to positively impact health care delivery, medical documentation, surgical training, and patient safety. Further high-quality scientific research is required to formally appraise Google Glass in the clinical setting.

Surgical procedures for spinal lipoma or tethered spinal cord after myelomeningocele (MMC) repair are often difficult and complicated, because the anatomical structures can be deformed in complex and unpredictable ways. Imaging helps the surgeon understand the patient's spinal anatomy. Whereas two-dimensional images provide only limited information for surgical planning, three-dimensional (3D) reconstructed computed tomography (CT)-magnetic resonance (MR) fusion images produce clearer representations of the spinal regions. Here we describe simple and quick methods for obtaining 3D reconstructed CT-MR fusion images for preoperative planning of surgical procedures using the iPlan cranial (BrainLAB AG, Feldkirchen, Germany) neuronavigation software. 3D CT images of the vertebral bone were combined with heavily T 2 -weighted MR images of the spinal cord, lipoma, cerebrospinal fluid (CSF) space, and nerve root through a process of fusion, segmentation, and reconstruction of the 3D images. We also used our procedure called 'Image Overlay' to directly project the 3D reconstructed image onto the body surface using an light emitting diode (LED) projector. The final reconstructed 3D images took 10-30 minutes to obtain, and provided the surgeon with a representation of the individual pathological structures, so enabled the design of effective surgical plans, even in patients with bony deformity such as scoliosis. None of the 19 patients treated based on our 3D reconstruction method has had neurological complications, except for CSF leakage. This 3D reconstructed imaging method, combined with Image Overlay, improves the visual understanding of complicated surgical situations, and should improve surgical efficiency and outcome. (author)

Summary Introduction Increased case volumes and training are associated with better surgical outcomes. However, the impact of pediatric urology sub-specialization on perioperative complication rates is unknown. Objectives To determine the presence and magnitude of difference in rates of common postoperative complications for elective pediatric urology procedures between specialization levels of urologic surgeons. The Nationwide Inpatient Sample (NIS), a nationally representative administrative database, was used. Study Design The NIS (1998–2009) was retrospectively reviewed for pediatric (≤18 years) admissions, using ICD-9-CM codes to identify urologic surgeries and National Surgical Quality Improvement Program (NSQIP) inpatient postoperative complications. Degree of pediatric sub-specialization was calculated using a Pediatric Proportion Index (PPI), defined as the ratio of children to total patients operated on by each provider. The providers were grouped into PPI quartiles: Q1, 0–25% specialization; Q2, 25–50%; Q3, 50–75%; Q4, 75–100%. Weighted multivariate analysis was performed to test for associations between PPI and surgical complications. Results A total of 71,479 weighted inpatient admissions were identified. Patient age decreased with increasing specialization: Q1, 7.9 vs Q2, 4.8 vs Q3, 4.8 vs Q4, 4.6 years, PSpecialization was not associated with race (P>0.20), gender (P>0.50), or comorbidity scores (P=0.10). Mortality (1.5% vs 0.2% vs 0.3% vs 0.4%, Pspecialization. Patients treated by more highly specialized surgeons incurred slightly higher costs (Q2, +4%; Q3, +1%; Q4 + 2%) but experienced shorter length of hospital stay (Q2, –5%; Q3, –10%; Q4, –3%) compared with the least specialized providers. A greater proportion of patients treated by Q1 and Q3 specialized urologists had CCS ≥2 than those seen by Q2 or Q4 urologists (12.5% and 12.2%, respectively vs 8.4% and 10.9%, respectively, P=0.04).

Study Design Study protocol for a randomized controlled trial and a prospective cohort. Background The number of arthroscopic surgical procedures for patients with femoroacetabular impingement syndrome (FAIS) has significantly increased worldwide, but high-quality evidence of the effect of such interventions is lacking. Objectives The primary objective will be to determine the efficacy of hip arthroscopic procedures compared to sham surgery on patient-reported outcomes for patients with FAIS (HIP ARThroscopy International [HIPARTI] Study). The secondary objective will be to evaluate prognostic factors for long-term outcome after arthroscopic surgical interventions in patients with FAIS (Hip ARthroscopy Prospective [HARP] Study). Methods The HIPARTI Study will include 140 patients and the HARP Study will include 100 patients. The international Hip Outcome Tool-33 will be the primary outcome measure at 1 year. Secondary outcome measures will be the Hip disability and Osteoarthritis Outcome Score, Arthritis Self-Efficacy Scale, fear of movement (Tampa Scale of Kinesiophobia), Patient-Specific Functional Scale, global rating of change score, and expectations. Other outcomes will include active hip range of motion, hip muscle strength tests, functional performance tests, as well as radiological assessments using radiographs and magnetic resonance imaging. Conclusion To determine the true effect of surgery, beyond that of placebo, double-blinded placebo-controlled trials including sham surgery are needed. The HIPARTI Study will direct future evidence-based treatment of FAIS. Predictors for long-term development and progression of degenerative changes in the hip are also needed for this young patient group with FAIS; hence, responders and nonresponders to treatment could be determined.

Currently, there is a tendency to perform surgical procedures via laparoscopic or thoracoscopic access. However, even with the impressive technological advancement in surgical materials, such as improvement in quality of monitors, light sources, and optical fibers, surgeons have to face simple problems that can greatly hinder surgery by video. One is the formation of "fog" or residue buildup on the lens, causing decreased visibility. Intracavitary techniques for cleaning surgical optics and preventing fog formation have been described; however, some of these techniques employ the use of expensive and complex devices designed solely for this purpose. Moreover, these techniques allow the cleaning of surgical optics when they becomes dirty, which does not prevent the accumulation of residue in the optics. To solve this problem we have designed a device that allows cleaning the optics with no surgical stops and prevents the fogging and residue accumulation. The objective of this study is to evaluate through experimental testing the effectiveness of a simple device that prevents the accumulation of residue and fogging of optics used in surgical procedures performed through thoracoscopic or laparoscopic access. Ex-vivo experiments were performed simulating the conditions of residue presence in surgical optics during a video surgery. The experiment consists in immersing the optics and catheter set connected to the IV line with crystalloid solution in three types of materials: blood, blood plus fat solution, and 200 mL of distilled water and 1 vial of methylene blue. The optics coupled to the device were immersed in 200 mL of each type of residue, repeating each immersion 10 times for each distinct residue for both thirty and zero degrees optics, totaling 420 experiments. A success rate of 98.1% was observed after the experiments, in these cases the device was able to clean and prevent the residue accumulation in the optics.

The objectives of this study were to examine demographic and clinicopathologic characteristics and to determine the effects of primary surgery, surgical staging and the extensiveness of staging. In a retrospective Turkish multicenter study, 539 patients, from 14 institutions, with borderline ovarian tumors were investigated. Some of the demographic, clinical and surgical characteristics of the cases were evaluated. The effects of type of surgery, surgical staging; complete or incomplete staging on survival rates were calculated by using Kaplan-Meier method. The median age at diagnosis was 40 years (range 15-84) and 71.1% of patients were premenopausal. The most common histologic types were serous and mucinous. Majority of the staged cases were in Stage IA (73.5%). 242 patients underwent conservative surgery. Recurrence rates were significantly higher in conservative surgery group (8.3% vs. 3%). Of all patients in this study, 294 (54.5%) have undergone surgical staging procedures. Of the patients who underwent surgical staging, 228 (77.6%) had comprehensive staging including lymphadenectomy. Appendectomy was performed on 204 (37.8%) of the patients. The median follow-up time was 36 months (range 1-120 months). Five-year survival rate was 100% and median survival time was 120 months. Surgical staging, lymph node sampling or dissection and appendectomy didn't cause any difference on survival. Comprehensive surgical staging, lymph node sampling or dissection and appendectomy are not beneficial in borderline ovarian tumors surgical management. © 2013.

Most surgical discharges (54%) at the average hospital are for procedures performed no more often than once per month at that hospital. We hypothesized that such uncommon procedures would be associated with an even greater percentage of the total cost of performing all surgical procedures at that hospital. Observational study. State of Texas hospital discharge abstract data: 4th quarter of 2015 and 1st quarter of 2016. Inpatients discharged with a major therapeutic ("operative") procedure. For each of N=343 hospitals, counts of discharges, sums of lengths of stay (LOS), sums of diagnosis related group (DRG) case-mix weights, and sums of charges were obtained for each procedure or combination of procedures, classified by International Classification of Diseases version 10 Procedure Coding System (ICD-10-PCS). Each discharge was classified into 2 categories, uncommon versus not, defined as a procedure performed at most once per month versus those performed more often than once per month. Major procedures performed at most once per month per hospital accounted for an average among hospitals of 68% of the total inpatient costs associated with all major therapeutic procedures. On average, the percentage of total costs associated with uncommon procedures was 26% greater than expected based on their share of total discharges (Pcosts among surgical patients can be attributed to procedures performed at most once per month per hospital. The finding that such uncommon procedures account for a large percentage of costs is important because methods of cost accounting by procedure are generally unsuitable for them.

The transition from basic skills training in a skills lab to procedure training in the operating theater using the traditional master-apprentice model (MAM) lacks uniformity and efficiency. When the supervising surgeon performs parts of a procedure, training opportunities are lost. To minimize this intervention by the supervisor and maximize the actual operating time for the trainee, we created a new training method called INtraoperative Video-Enhanced Surgical Training (INVEST). Ten surgical residents were trained in laparoscopic cholecystectomy either by the MAM or with INVEST. Each trainee performed six cholecystectomies that were objectively evaluated on an Objective Structured Assessment of Technical Skills (OSATS) global rating scale. Absolute and relative improvements during the training curriculum were compared between the groups. A questionnaire evaluated the trainee's opinion on this new training method. Skill improvement on the OSATS global rating scale was significantly greater for the trainees in the INVEST curriculum compared to the MAM, with mean absolute improvement 32.6 versus 14.0 points and mean relative improvement 59.1 versus 34.6% (P=0.02). INVEST significantly enhances technical and procedural skill development during the early learning curve for laparoscopic cholecystectomy. Trainees were positive about the content and the idea of the curriculum.

The aim of this study was to describe the number and trend of surgical procedures for female genital fistula in England. An online search of Hospital Episode Statistics (HES) data was carried out. Data were available for the 4-year period from 2002-03 until 2005-06. The total number of surgical procedures carried out for female genital fistula steadily increased by 28.7% from 616 in 2002-03 to 793 in 2005-06. The number of surgical procedures performed for rectovaginal fistula exceeded the total number of surgical procedures carried out for vesicovaginal and urethrovaginal fistula in each year of the study period. This pattern needs to be monitored and investigated further.

History revealed that patient had undergone partial maxillectomy for squamous cell carcinoma 7 years back. The patient also has been wearing obturator which was loose when the patient reported to the department. On examination, the site of surgery was the maxillary right buccal sulcus area and a part of the hard palate including teeth number 11, 12, 13, 14, 15, 16, 17. The presented defect situation corresponded to a Class I situation (resection performed along the palatalmidline according to the Aramany classification of defects. The surgical site showed complete healing. A hollow-bulb obturator was fabricated for rehabilitation of the defect. Conclusion: The extensive surgical procedures necessary to eradicate cancer of the head and neck and to prevent local recurrence or regional metastasis often leave extremely large physical defects which present almost insurmountable surgical difficulties in restoring acceptable function or esthetics. The prosthesis rehabilitated the patient in terms of function by providing better masticatory efficiency, phonetics by adding resonance to the voice, hence improving the clarity of speech and also improved the esthetics of the patient.

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

Situs inversus totalis (SIT) is a rare condition, in which there is transposition of the thoraco-abdominal organs. This situation leads to diagnostic and therapeutic difficulties in patients with acute surgical abdomen. The objective of this report is to present the case of a patient who presented with colonic pain in the epigastrium and left hypochondrium, in which the diagnosis of SIT, cholelithiasis and choledocholithiasis was reached after the respective imaging studies. Once the diagnosis was made, treatment was performed through retrograde endoscopic cholangiopancreatography (ERCP) and subsequent surgical exploration of bile ducts. Both procedures were failed due to technical difficulties generated by the patient's condition. In conclusion, in spite of the report of successful cases in the literature of ERCP and surgical treatment of the biliary tract in SIT, there may be situations that do not allow a successful approach, so meticulous surgical planning and the use of support methods are necessary In the management of these patients.

To evaluate the effectiveness of surgical treatment performed in patients with double elevator palsy (DEP). Patients diagnosed with congenital DEP between April 2003 and March 2007 were included in the study. The cases with positive traction test had inferior rectus (IR) recession followed by full tendon width muscle transposition Knapp surgery or partial tendon width transposition operation, while those without positive traction test underwent transposition procedure alone. Transposition surgery was combined with recession and resection of horizontal rectus muscles in patients with exotropia according to the amount of horizontal deviation. Eyelid surgery was applied in patients with ptosis following strabismus surgery. The average age of 13 patients was 14+/-32.5 years (range, 3-60 years). Five patients (38%) were female and 8 patients (62%) were male. The mean preoperative hypotropia was decreased from 29.2+/-3.5 prism diopters (PD) (range, 16-45 PD) to 2.6+/-2.8 PD (range, 0-6 PD) postoperatively. The median amount of horizontal deviation in patients with exotropia (n=4) was 30 PD (range, 25-45 PD) preoperatively; it was reduced to 2 PD (range, 0-8 PD) postoperatively. Mean follow-up period was 14.1+/-2.8 months (range, 6-31 months). Five patients (38%) underwent eyelid surgery, and all achieved cosmetically satisfactory results. Transposition surgery alone or combined with IR recession is an effective procedure in treatment of double elevator palsy. In patients with moderate horizontal deviations, recession and resection of horizontal rectus muscles combined with transposition provide correction of the horizontal deviation at the same time.

Full Text Available Carpal tunnel syndrome (CTS is the most common entrapment neuropathy and a frequent cause of sick leaves because of work-related hand overload. That is why an early diagnosis and adequate treatment (conservative or surgical are essential for optimal patient management. Aim: The aim of the study is to assess the usefulness of high-frequency ultrasound in CTS for the assessment of patient eligibility for surgical treatment. Material and methods: The study involved 62 patients (50 women and 12 men, aged 28–70, mean age 55.2 with scheduled surgeries of CTS on the basis of clinical symptoms, physical examination performed by a neurosurgeon and a positive result of EMG testing. The ultrasound examinations of the wrist were performed in all these patients. On the basis of the collected data, the author has performed multiple analyses to confi rm the usefulness of ultrasound imaging in assessing patient eligibility for surgical treatment of CTS. Results: US examinations showed evidence of median nerve compression at the level of the carpal tunnel in all of the examined patients. This was further confi rmed during surgical procedures. The mean value of the cross-sectional area at the proximal part of the pisiform bone was 17.45 mm2 (min. 12 mm2 , max. 31 mm2 . Nerve hypoechogenicity proximal to the nerve compression site was visible in all 62 patients (100%. Increased nerve vascularity on the transverse section was present in 50 patients (80.65%. Conclusions: Ultrasonography with the use of high-frequency transducers is a valuable diagnostic tool both for assessing patient eligibility for surgical treatment of CTS, and in postoperative assessment of the treatment efficacy.

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

Efficacy and safety of antibiotic prophylaxis (AP) for prevention of infective endocarditis (IE) in patients with predisposing cardiac condition (PCC) undergoing invasive procedures is still debated. We sought to assess the prevalence of PCC, the type of interventional procedures preceding the onset of symptoms, and the usefulness of AP in a large cohort of consecutive patients with definite IE. We examined 677 (median age 65.34 years; male 492 [73%]) consecutive patients with IE enrolled from July 2007 through 2010 into the Italian Registry of Infective Endocarditis. Predisposing cardiac condition was present in 341 patients (50%).Thirty-two patients (4.7%) underwent dental procedures. Of 20 patients with PCC undergoing dental procedure, 13 had assumed AP. Viridans group streptococci were isolated from blood cultures in 8 of 20 patients with PCC and prior dental procedure. Nondental procedures preceded IE in 139 patients (21%). They were significantly older and had more comordibities compared with patients undergoing dental procedures. Predisposing cardiac condition was identified in 91 patients. Perioperative antimicrobial prophylaxis was administered to 67 patients. Staphylococcus aureus was the most frequent causative agent. Cardiac surgery was necessary in 85 patients (20 with prior dental and 65 with nondental procedure). Surgical mortality (12% vs 0%, P = .03) and hospital mortality (23% vs 3%, P = .001) were significantly larger among patients with nondental procedures. In a large unselected cohort of patients with IE, the incidence of preceding dental procedures was minimal. The number of cases potentially preventable by means of AP was negligible. Nondental procedures were more frequent than dental procedures and were correlated with poorer prognosis. Copyright © 2016 Elsevier Inc. All rights reserved.

There has been a dramatic rise in office-based surgery. However, due to wide variations in regulatory standards, the safety of office-based aesthetic surgery has been questioned. This study compares complication rates of cosmetic surgery performed at office-based surgical suites (OBSS) to ambulatory surgery centers (ASCs) and hospitals. A prospective cohort of patients undergoing cosmetic surgery between 2008 and 2013 were identified from the CosmetAssure database (Birmingham, AL). Patients were grouped by type of accredited facility where the surgery was performed: OBSS, ASC, or hospital. The primary outcome was the incidence of major complication(s) requiring emergency room visit, hospital admission, or reoperation within 30 days postoperatively. Potential risk factors including age, gender, body mass index (BMI), smoking, diabetes, type of procedure, and combined procedures were reviewed. Of the 129,007 patients (183,914 procedures) in the dataset, the majority underwent the procedure at ASCs (57.4%), followed by hospitals (26.7%) and OBSS (15.9%). Patients operated in OBSS were less likely to undergo combined procedures (30.3%) compared to ASCs (31.8%) and hospitals (35.3%, P procedures. Plastic surgeons should continue to triage their patients carefully based on other significant comorbidities that were not measured in this present study.

To identify the characteristic features of pneumothorax patients treated surgically. The retrospective study was conducted at Gazi Yasargil Education and Research Hospital Thoracic Surgery Clinic, Diyarbakir, Turkey and comprised records of pneumothorax patients from January 2004 to December 2014. They were divided into two groups as spontaneous and traumatic. Patients who had not undergone any surgical intervention were excluded. Mean age, gender distribution, location of the disease, type of pneumothorax, and treatment method were noted. Among patients with spontaneous pneumothorax, age and months distribution, smoking habits, pneumothorax size, and treatment method were assessed. The effect of gender, location, comorbid disease, smoking, subgroup of disease, and pneumothorax size on surgical procedures were also investigated. The mean age of the 672 patients in the study was 34.5±6.17 years. There were 611(91%) men and 61(9%) women. Disease was on the right side in 360(53.6%) patients, on the left side in 308(45.8%), and bilateral in 4(0.59%). Besides, 523(77.8%) patients had spontaneous, and 149(22.7%) had traumatic pneumothorax. Overall, 561(83.5%) patients had been treated with tube thoracostomy, whereas 111(16.5%) were treated with thoracotomy/thoracoscopic surgery. The presence of comorbid diseases, being primary, and being total or subtotal according to partial were found to create predisposition to thoracotomy/ thoracoscopic surgery (ppneumothorax being total, the presence of comorbid diseases, and the increase in pneumothorax size, thoracotomy or thoracoscopic surgery is preferred.

To develop, empirical test, and validate an instrument measuring patient participation in surgical treatment decision-making from healthcare professionals' perspective. Since the advent of New Public Management in many Western countries, patient participation in healthcare decision-making has been considered to be a best practice. A common notion is that well-educated and well-informed public want to choose their own treatments and providers and want to ask questions about the quality of their health services. Survey. A self-report-measuring instrument was designed and administered to 620 healthcare professionals. Items were developed, validated and tested by 451 nurses and physicians working in six surgical wards in a University Hospital in Norway. A 16-item scale with the following four dimensions was developed: information dissemination, formulation of options, integration of information and control. Factor analysis procedures and reliability testing were performed. A one-way, between-groups analysis of variance was conducted to compare doctors' and nurses' opinions on four dimensions of patient participation in surgical treatment decision-making. This article shows that patient participation in surgical treatment decision-making can be measured by a 16-item scale and four distinct dimensions. The analysis demonstrated a reasonable level of construct validity and reliability. Nurses and physicians have a positive attitude towards patient participation overall, but the two groups differ in the extent to which they accept the idea of patient participation in treatment decision-making. The instrument can be a tool for managers and healthcare professionals in the implementation of patient participation in clinical practice. Data from the instrument can be useful to identify health services being provided and what areas that could strengthen patient participation. © 2013 Blackwell Publishing Ltd.

We developed a new radiosensitizer containing hydrogen peroxide and sodium hyaluronate for topical tumor injection for various types of tumors, and the method was named KORTUC II (Kochi Oxydol-Radiation Therapy for Unresectable Carcinomas, Type II). KORTUC II trial was accepted by our local ethical committee concerning of the injection for advanced skin cancer, advanced bone/soft tissue malignant neoplasms, breast cancer of op refused or aged patients, and metastatic lymph nodes. Concerning breast cancer, ten patients were enrolled in the KORTUC II trial upon fully informed consent. All of them showed clinically complete response by the new enzyme-targeting radiosensitization treatment (KORTUC II) without any severe complications excluding mild dermatitis (grade I). Nine of the 10 patients have so far shown neither local recurrence nor distant metastasis, and the mean follow-up period at the end of December 2007 was still short and approximately 12 months. Especially for patients with breast cancer, breast-conservation treatment without any surgical procedure can be performed by using our new radiosensitizer for topical injection into the tumor tissue.

Full Text Available Background: A deficiency of magnesium is of clinical importance in hospitalized patients. The prevalence of hypomagnesaemia is high in critically ill patients. Knowing the important role of magnesium in surgical cases, it is necessary to anticipate and diagnose magnesium deficiency prior to surgery and in the immediate postoperative period to correct it. Aims and Objectives: The aim of this study was to analyse serum magnesium levels in patients undergoing emergency surgical procedures, planned surgical procedures and normal healthy matched controls and to compare the serum magnesium levels in all the three groups. Materials and Methods: The study participants were divided into three groups: i Group I: patients undergoing emergency major surgery ii Group II: patients undergoing planned major surgery iii Group III: normal healthy controls. Serum Magnesium investigation was done by Xylidyl Blue Method using UV-1800/Shimadzu UV-Spectrophotometer. Results: The mean serum Magnesium in control group was found to be 2.16 ± 0.30 mg/dl. In patients undergoing planned surgery, pre-operative serum magnesium was normal (2.16 ± 0.22 mg/dl but decreased significantly on postoperative day 3 (1.63 ± 0.27 mg/dl and day 6 (1.97 ± 0.12 mg/dl and returned to normal level by post-operative day 9 (2.14 ± 0.14 mg/dl compared to controls. In patients undergoing emergency surgery, serum magnesium was decreased pre-operatively (1.90 ± 0.48 mg/dl.Further significant reduction was found at post-operative day 3 (1.38 ± 0.28 mg/dl, day 6 (1.59 ± 0.30 mg/dl and day 9 (1.88 ± 0.46 mg/dl compared to controls. Mean serum Magnesium overall in emergency surgery patients was reduced significantly compared to planned surgery patients. Conclusion: A transient fall in the serum Magnesium as compared to its pre-operative level was seen in every patient undergoing surgical procedure due to surgical stress. In patients undergoing emergency surgical procedure, the decrease was

BACKGROUND CONTEXT: Choosing the best surgical treatment for patients with spinal metastases remains a significant challenge for spine surgeons. There is currently no gold standard for surgical treatments. The Aarhus Spinal Metastases Algorithm (ASMA) was established to help surgeons choose...... the most appropriate surgical intervention for patients with spinal metastases. PURPOSE: The purpose of this study was to evaluate the clinical outcome of stratified surgical interventions based on the ASMA, which combines life expectancy and the anatomical classification of patients with spinal metastases...... survival times in the five surgical groups determined by the ASMA were 2.1 (TS 0-4, TC 1-7), 5.1 (TS 5-8, TC 1-7), 12.1 (TS 9-11, TC 1-7 or TS 12-15, TC 7), 26.0 (TS 12-15, TC 4-6), and 36.0 (TS 12-15, TC 1-3) months. The 30-day mortality rate was 7.5%. Postoperative neurological function was maintained...

Abdominal surgical site infections (SSI) cause substantial morbidity and mortality for patients undergoing operative procedures. We determined the incidence of and risk factors for SSI after abdominal surgery in the Department of Abdominal Surgery at the University Clinical Centre of Kosovo (UCCK). Prospective surveillance of patients undergoing abdominal surgery was performed between December 2005 and June 2006. CDC definitions were followed to detect SSI and study forms were based on Europe Link for Infection Control through Surveillance (HELICS) protocol. A total of 253 surgical interventions in 225 patients were evaluated. The median age of patients was 42 years and 55.1% of them were male. The overall incidence rate of SSI was 12%. Follow-up was achieved for 84.1% of the procedures. For patients with an SSI, the median duration of hospitalization was 9 days compared with 4 days for those without an SSI (p 2, use of antibiotic prophylaxis and NNIS class of > 2 were all significant at p < .001. The SSI rates for the NNIS System risk classes 0, 1 and 2-3 were 4.2%, 46.7% and 100%, respectively. SSI caused considerable morbidity among surgical patients in UCCK. Appropriate active surveillance and infection control measures should be introduced during preoperative, intra-operative, and postoperative care to reduce infection rates.

Pelvic denervation procedures for dysmenorrhea.

Science.gov (United States)

Ramirez, Christina; Donnellan, Nicole

2017-08-01

Chronic pelvic pain and dysmenorrhea are common conditions affecting reproductive-age women. Surgical pelvic denervation procedures may be a treatment option for women with midline dysmenorrhea, in which medical management is declined by the patient, ineffective at managing symptoms, or medically contraindicated. This review describes the surgical techniques and complications associated with pelvic denervation procedures as well as the current evidence for these procedures in women with primary dysmenorrhea and dysmenorrhea secondary to endometriosis. Presacral neurectomy is the preferred pelvic denervation procedure in patients with primary dysmenorrhea and midline chronic pelvic pain associated with endometriosis. In patients with endometriosis presacral neurectomy is a useful adjunct to excision or ablation of all endometrial lesions to improve postoperative pain relief. There is no additional patient benefit of performing combined presacral neurectomy and uterine nerve ablation procedures. Pelvic denervation procedures can be performed safely and quickly with a low risk of complication if the surgeon is knowledgeable and skilled in operating in the presacral space. Patients should be adequately counseled on expected success rates and potential complications associated with pelvic denervation procedures.

To assess the nutritional response of a group of critically ill patients, as well as the differences in the response to nutritional support between medical and surgical patients. One-year long retrospective study including critically ill patients on artificial nutrition for 7 days. Throughout the first week, three nutritional biochemical controls were done that included albumin, prealbumin, transferrin, cholesterol, and electrolytes. Other data gathered were: nutritional risk index, age, gender, weight, height, APACHE, delay of onset of nutritional support, access route, predicted and real caloric intake, medical or surgical patient, hospital stay, duration of the central venous catheter, urinary tube, and/or mechanical ventilation, incidence and density of incidence of nosocomial infections. Sixty-three patients were studied, 30 (47%) medical and 33 (53%) surgical/trauma patients, with a usage of EN higher among medical patients (16/30, 53% vs. 5/33, 15%), PN higher among surgical patients (25/33, 76%), and mixed nutrition similar in both groups (5 medical and 3 surgical patients) (p = 0.001). There were no differences between medical and surgical patients regarding: both predicted and real caloric and nitrogenous intake, APACHE, delay of onset of nutrition, phosphorus, magnesium or glucose levels, mortality and incidence of nosocomial infections. There were no differences either in hospital stay or use of mechanical ventilation, although these tended to be lower in surgical patients. The baseline biochemical parameters did not show differences between both groups, although they were worse among surgical patients. These patients presented during the study period steady albumin levels with improvement in the remaining parameters, whereas medical patients showed a decrease in albumin and transferrin levels, steady prealbumin levels, and slightly improvement in cholesterol levels. We have observed higher usage of PN among surgical patients, which showed worse

To determine the impact of surgical site infections (SSIs) on health care costs following common ambulatory surgical procedures throughout the cost distribution. Data on costs of SSIs following ambulatory surgery are sparse, particularly variation beyond just mean costs. We performed a retrospective cohort study of persons undergoing cholecystectomy, breast-conserving surgery, anterior cruciate ligament reconstruction, and hernia repair from December 31, 2004 to December 31, 2010 using commercial insurer claims data. SSIs within 90 days post-procedure were identified; infections during a hospitalization or requiring surgery were considered serious. We used quantile regression, controlling for patient, operative, and postoperative factors to examine the impact of SSIs on 180-day health care costs throughout the cost distribution. The incidence of serious and nonserious SSIs was 0.8% and 0.2%, respectively, after 21,062 anterior cruciate ligament reconstruction, 0.5% and 0.3% after 57,750 cholecystectomy, 0.6% and 0.5% after 60,681 hernia, and 0.8% and 0.8% after 42,489 breast-conserving surgery procedures. Serious SSIs were associated with significantly higher costs than nonserious SSIs for all 4 procedures throughout the cost distribution. The attributable cost of serious SSIs increased for both cholecystectomy and hernia repair as the quantile of total costs increased ($38,410 for cholecystectomy with serious SSI vs no SSI at the 70th percentile of costs, up to $89,371 at the 90th percentile). SSIs, particularly serious infections resulting in hospitalization or surgical treatment, were associated with significantly increased health care costs after 4 common surgical procedures. Quantile regression illustrated the differential effect of serious SSIs on health care costs at the upper end of the cost distribution.

Surgical Outcome in Patients with Spontaneous Supratentorial Intracerebral Hemorrhage

Full Text Available The aim of the paper was to evaluate the surgical outcome in patients with spontaneous supratentorial intracerebral hemorrhage (ICH after surgical intervention, in respect to the initial clinical conditions, age, sex, hemispheric side and anatomic localization of ICH. Thirty-eight surgically treated patients with spontaneous supratentorial intracerebral hemorrhage were included in the study. The surgical outcome was evaluated three months after the initial admission, according to the Glasgow Outcome Scale (GOS. The surgical treatment was successful in 14 patients (37%, whereas it was unsuccessful in 24 patients (63%. We have detected a significant negative correlation between the Glasgow Coma Scale (GCS scores on admission and the GOS scores after three months, suggesting worse neurological outcome in patients with initially lower GCS scores. The surgical outcome in patients with ICH was not affected by the sex, the hemispheric side and the anatomic localization of ICH, but the age of the patients was estimated as a significant factor for their functional outcome, with younger patients being more likely to be treated successfully. The surgical outcome is affected from the initial clinical state of the patients and their age. The treatment of ICH is still an unsolved clinical problem and the development of new surgical techniques with larger efficiency in the evacuation of the hematoma is necessary, thus making a minimal damage to the normal brain tissue, as well as decreasing the possibility of postoperative bleeding.

Evaluation of Patient Radiation Dose during Cardiac Interventional Procedures: What Is the Most Effective Method?

International Nuclear Information System (INIS)

Chida, K.; Saito, H.; Ishibashi, T.; Zuguchi, M.; Kagaya, Y.; Takahashi, S.

2009-01-01

Cardiac interventional radiology has lower risks than surgical procedures. This is despite the fact that radiation doses from cardiac intervention procedures are the highest of any commonly performed general X-ray examination. Maximum radiation skin doses (MSDs) should be determined to avoid radiation-associated skin injuries in patients undergoing cardiac intervention procedures. However, real-time evaluation of MSD is unavailable for many cardiac intervention procedures. This review describes methods of determining MSD during cardiac intervention procedures. Currently, in most cardiac intervention procedures, real-time measuring of MSD is not feasible. Thus, we recommend that physicians record the patient's total entrance skin dose, such as the dose at the interventional reference point when it can be monitored, in order to estimate MSD in intervention procedures

Acute limb ischemia in cancer patients: should we surgically intervene?

LENUS (Irish Health Repository)

Tsang, Julian S

2012-02-01

BACKGROUND: Cancer patients have an increased risk of venous thromboembolic events. Certain chemotherapeutic agents have also been associated with the development of thrombosis. Reported cases of acute arterial ischemic episodes in cancer patients are rare. METHODS: Patients who underwent surgery for acute limb ischemia associated with malignancy in a university teaching hospital over a 10-year period were identified. Patient demographics, cancer type, chemotherapy use, site of thromboembolism, treatment and outcome were recorded. RESULTS: Four hundred nineteen patients underwent surgical intervention for acute arterial ischemia, 16 of these patients (3.8%) had associated cancer. Commonest cancer sites were the urogenital tract (n = 5) and the lungs (n = 5). Eight patients (50%) had been recently diagnosed with cancer, and four (25%) of these cancers were incidental findings after presentation with acute limb ischemia. Four patients (25%) developed acute ischemia during chemotherapy. The superficial femoral artery was the most frequent site of occlusion (50%), followed by the brachial (18%) and popliteal (12%) arteries. All patients underwent thromboembolectomy, but two (12%) patients subsequently required a bypass procedure. Six patients (37%) had limb loss, and in-patient mortality was 12%. Histology revealed that all occlusions were due to thromboembolism, with no tumor cells identified. At follow-up, 44% of patients were found to be alive after 1 year. CONCLUSION: Cancer and chemotherapy can predispose patients to acute arterial ischemia. Unlike other reports that view this finding as a preterminal event most appropriately treated by palliative measures, in this series, early diagnosis and surgical intervention enabled limb salvage and patient survival.

Full Text Available Purpose Currently, holmium laser enucleation of the prostate (HoLEP and transurethral resection of the prostate (TURP are the standard surgical procedures used to treat benign prostatic hyperplasia (BPH. Several recent studies have demonstrated that the surgical management of BPH in patients with detrusor underactivity (DU can effectively improve voiding symptoms, but comparative data on the efficacy of HoLEP and TURP are insufficient. Therefore, we compared the short-term surgical outcomes of HoLEP and TURP in patients with DU. Methods From January 2010 to May 2015, 352 patients underwent HoLEP or TURP in procedures performed by a single surgeon. Of these patients, 56 patients with both BPH and DU were enrolled in this study (HoLEP, n=24; TURP, n=32. Surgical outcomes were retrospectively compared between the 2 groups. DU was defined as a detrusor pressure at maximal flow rate of <40 cm H2O as measured by a pressure flow study. Results The preoperative characteristics of patients and the presence of comorbidities were comparable between the 2 groups. The TURP group showed a significantly shorter operative time than the HoLEP group (P=0.033. The weight of the resected prostate was greater in the HoLEP group, and postoperative voiding parameters, including peak flow rate and postvoid residual urine volume were significantly better in the HoLEP group than in the TURP group. Conclusions HoLEP can be effectively and safely performed in patients with DU and can be expected to have better surgical outcomes than TURP in terms of the improvement in lower urinary tract symptoms.

Distinct patterns in the gut microbiota after surgical or medical therapy in obese patients

Full Text Available Bariatric surgery is highly successful in improving health compared to conventional dietary treatments. It has been suggested that the gut microbiota is a relevant factor in weight loss after bariatric surgery. Considering that bariatric procedures cause different rearrangements of the digestive tract, they probably have different effects on the gut microbiota. In this study, we compared the impact of medical treatment, sleeve gastrectomy and Roux-en-Y gastric bypass on the gut microbiota from obese subjects. Anthropometric and clinical parameters were registered before, 6 and 12 months after treatment. Fecal samples were collected and microbiota composition was studied before and six months post treatment using 16S rRNA gene sequencing and qPCR. In comparison to dietary treatment, changes in intestinal microbiota were more pronounced in patients subjected to surgery, observing a bloom in Proteobacteria. Interestingly, Bacteroidetes abundance was largely different after six months of each surgical procedure. Furthermore, changes in weight and BMI, or glucose metabolism, correlated positively with changes in these two phyla in these surgical procedures. These results indicate that distinct surgical procedures alter the gut microbiota differently, and changes in gut microbiota might contribute to health improvement. This study contributes to our understanding of the impact of weight loss surgery on the gut microbiota, and could be used to replicate this effect using targeted therapies.

Implant dentistry has been established as a predictable treatment with excellent clinical success to replace missing or nonrestorable teeth. A successful esthetic implant reconstruction is predicated on two fundamental components: the reproduction of the natural tooth characteristics on the implant crown and the establishment of soft tissue housing that will simulate a healthy periodontium. In order for an implant to optimally rehabilitate esthetics, the peri-implant soft tissues must be preserved and/or augmented by means of periodontal surgical procedures. Clinicians who practice implant dentistry should strive to achieve an esthetically successful outcome beyond just osseointegration. Knowledge of a variety of available techniques and proper treatment planning enables the clinician to meet the ever-increasing esthetic demands as requested by patients. The purpose of this paper is to enhance the implant surgeon's rationale and techniques beyond that of simply placing a functional restoration in an edentulous site to a level whereby an implant-supported restoration is placed in reconstructed soft tissue, so the site is indiscernible from a natural tooth.

This study evaluated outcomes of surgical treatment for carpal valgus in New World camelids and correlated successful outcome (absence of carpal valgus determined by a veterinarian) with patient characteristics and radiographic features. Univariable and multivariable analyses of retrospective case data in 19 camelids (33 limbs) treated for carpal valgus between 1987 and 2010 revealed that procedures incorporating a distal radial transphyseal bridge were more likely (P = 0.03) to result in success after a single surgical procedure. A greater degree of angulation (> 19°, P = 0.02) and younger age at surgery (< 4 months, P = 0.03) were associated with unsuccessful outcome. Overall, 74% of limbs straightened, 15% overcorrected, and 11% had persistent valgus following surgical intervention. To straighten, 22% of limbs required multiple procedures, not including implant removal. According to owners, valgus returned following implant removal in 4 limbs that had straightened after surgery.

BACKGROUND: In Ireland, specialist paediatric surgery is carried out in paediatric hospitals in Dublin. General surgeons\\/consultants in other surgical specialities provide paediatric surgical care in regional centres. There has been a failure to train general surgeons with paediatric skills to replace these surgeons upon retirement. AIM: To assess paediatric surgical workload in one regional centre to focus the debate regarding the future provision of general paediatric surgery in Ireland. METHODS: Hospital in-patient enquiry (HIPE) system was used to identify total number of paediatric surgical admissions and procedures. Cases assessed requiring hospital transfer. RESULTS: Of 17,478 surgical patients treated, 2,584 (14.8%) were under 14 years. A total of 2,154 procedures were performed. CONCLUSION: Regional centres without dedicated paediatric surgeons deliver care to large numbers of paediatric patients. The demand for care highlights the need for formal paediatric services\\/appropriate surgical training for general surgical trainees.

Surgical simulation has benefited from a surge in interest over the last decade as a result of the increasing need for a change in the traditional apprentice model of teaching surgery. However, despite the recent interest in surgical simulation as an adjunct to surgical training, most of the literature focuses on laparoscopic, endovascular, and endoscopic surgical simulation with very few studies scrutinizing open surgical simulation and its benefit to surgical trainees. The aim of this review is to summarize the current standard of available open surgical simulators and to review the literature on the benefits of open surgical simulation. Open surgical simulators currently used include live animals, cadavers, bench models, virtual reality, and software-based computer simulators. In the current literature, there are 18 different studies (including 6 randomized controlled trials and 12 cohort studies) investigating the efficacy of open surgical simulation using live animal, bench, and cadaveric models in many surgical specialties including general, cardiac, trauma, vascular, urologic, and gynecologic surgery. The current open surgical simulation studies show, in general, a significant benefit of open surgical simulation in developing the surgical skills of surgical trainees. However, these studies have their limitations including a low number of participants, variable assessment standards, and a focus on short-term results often with no follow-up assessment. The skills needed for open surgical procedures are the essential basis that a surgical trainee needs to grasp before attempting more technical procedures such as laparoscopic procedures. In this current climate of medical practice with reduced hours of surgical exposure for trainees and where the patient's safety and outcome is key, open surgical simulation is a promising adjunct to modern surgical training, filling the void between surgeons being trained in a technique and a surgeon achieving fluency in that

In many countries healthcare commissioning bodies (state or insurance-based) reimburse hospitals for their activity. The costs associated with post-graduate clinical training as part of this are poorly understood. This study quantified the financial revenue generated by surgical trainees in the out-patient clinic setting. A retrospective analysis of surgical out-patient ambulatory care appointments under 6 full-time equivalent Consultants (Attendings) in one hospital over 2 months. Clinic attendance lists were generated from the Patient Access System. Appointments were categorised as: 'new', 'review' or 'procedure' as per the Department of Health Payment by Results (PbR) Outpatient Tariff (Outpatient Treatment Function Code 104; Outpatient Procedure Code OPRSI1). During the study period 78 clinics offered 1184 appointments; 133 of these were not attended (11.2%). Of those attended 1029 had sufficient detail for analysis (98%). 261 (25.4%) patients were seen by a trainee. Applying PbR reimbursement criteria to these gave a projected annual income of £GBP 218,712 (€EU 266,527; $USD 353,657) generated by 6 surgical trainees (Residents). This is equivalent to approximately £GBP 36,452 (€EU 44,415; $USD 58,943) per trainee annually compared to £GBP 48,732 (€EU 59,378; $USD 78,800) per Consultant. This projected yearly income off-set 95% of the trainee's basic salary. Surgical trainees generated a quarter of the out-patient clinic activity related income in this study, with each trainee producing three-quarters of that generated by a Consultant. This offers considerable commercial value to hospitals. Although this must offset productivity differences and overall running costs, training bodies should ensure hospitals offer an appropriate return. In a competitive market hospitals could be invited to compete for trainees, with preference given to those providing excellence in training. Copyright © 2013 Surgical Associates Ltd.

Broer, P Niclas; Levine, Steven M; Juran, Sabrina

2014-03-01

The objective of this article was to evaluate past and current trends regarding aesthetic operations in the United States and to project future changes regarding such procedures. Cosmetic surgery statistics from the American Society for Aesthetic Plastic Surgery from 1997 to 2012 were analyzed by sex, age, and ethnic group. Then, using population projections from the U.S. Census Bureau based on the 2010 census, two projection scenarios of the expected number of aesthetic plastic surgery procedures were generated. The scenarios included the presumed occurrence and nonoccurrence of a recession like that which occurred in 2007. Aesthetic procedures are expected to grow from 1,688,694 in 2012 to 3,847,929 by 2030, representing an average annual growth rate of 7.1 percent. Should another recession of similar degree to the one in 2007 occur, procedures would increase to only 2,086,994, displaying an average annual growth percentage rate of 1.3 percent. Because the age distribution of the patient population will change, preferences for specific procedures according to age influence-and thus are reflected in-future demand for those procedures. Furthermore, the ethnic profile of patients will change significantly, with 32 percent of all procedures being performed on patients other than Caucasians by 2030. Demand for aesthetic plastic surgical procedures is expected to continue to grow, while depending on the economic performance at the macro level and changing demographic dynamics of the U.S. population. Considering all investigated factors and trends among all patients, the most commonly requested procedures by 2030 are likely to be (1) breast augmentations, (2) lipoplasties, and (3) blepharoplasties.

To evaluate the economic impact of obesity on hospital costs associated with the commonest nonbariatric, nonobstetrical surgical procedures. Health care costs and obesity are both rising. Nonsurgical costs associated with obesity are well documented but surgical costs are not. National cost estimates were calculated from the Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Sample (NIS) database, 2005-2009, for the highest volume nonbariatric nonobstetric procedures. Obesity was identified from the HCUP-NIS severity data file comorbidity index. Costs for obese patients were compared with those for nonobese patients. To control for medical complexity, each obese patient was matched one-to-one with a nonobese patient using age, sex, race, and 28 comorbid defined elements. Of 2,309,699 procedures, 439,8129 (19%) were successfully matched into 2 medically equal groups (obese vs nonobese). Adjusted total hospital costs incurred by obese patients were 3.7% higher with a significantly (P cost of $648 (95% confidence interval [CI]: $556-$736) compared with nonobese patients. Of the 2 major components of hospital costs, length of stay was significantly increased in obese patients (mean difference = 0.0253 days, 95% CI: 0.0225-0.0282) and resource utilization determined by costs per day were greater in obese patients due to an increased number of diagnostic and therapeutic procedures needed postoperatively (odds ratio [OR] = 0.94, 95% CI: 0.93-0.96). Postoperative complications were equivalent in both groups (OR = 0.97, 95% CI: 0.93-1.02). Annual national hospital expenditures for the largest volume surgical procedures is an estimated $160 million higher in obese than in a comparative group of nonobese patients.

Surgical smoke.

Surgical smoke is the gaseous by-product formed during surgical procedures. Most surgeons, operating theatre staff and administrators are unaware of its potential health risks. Surgical smoke is produced by various surgical instruments including those used in electrocautery, lasers, ultrasonic scalpels, high speed drills, burrs and saws. The potential risks include carbon monoxide toxicity to the patient undergoing a laparoscopic operation, pulmonary fibrosis induced by non-viable particles, and transmission of infectious diseases like human papilloma virus. Cytotoxicity and mutagenicity are other concerns. Minimisation of the production of surgical smoke and modification of any evacuation systems are possible solutions. In general, a surgical mask can provide more than 90% protection to exposure to surgical smoke; however, in most circumstances it cannot provide air-tight protection to the user. An at least N95 grade or equivalent respirator offers the best protection against surgical smoke, but whether such protection is necessary is currently unknown.

Large Variability in the Diversity of Physiologically Complex Surgical Procedures Exists Nationwide Among All Hospitals Including Among Large Teaching Hospitals.

Multiple previous studies have shown that having a large diversity of procedures has a substantial impact on quality management of hospital surgical suites. At hospitals with substantial diversity, unless sophisticated statistical methods suitable for rare events are used, anesthesiologists working in surgical suites will have inaccurate predictions of surgical blood usage, case durations, cost accounting and price transparency, times remaining in late running cases, and use of intraoperative equipment. What is unknown is whether large diversity is a feature of only a few very unique set of hospitals nationwide (eg, the largest hospitals in each state or province). The 2013 United States Nationwide Readmissions Database was used to study heterogeneity among 1981 hospitals in their diversities of physiologically complex surgical procedures (ie, the procedure codes). The diversity of surgical procedures performed at each hospital was quantified using a summary measure, the number of different physiologically complex surgical procedures commonly performed at the hospital (ie, 1/Herfindahl). A total of 53.9% of all hospitals commonly performed 3-fold larger diversity (ie, >30 commonly performed physiologically complex procedures). Larger hospitals had greater diversity than the small- and medium-sized hospitals (P 30 procedures (lower 99% CL, 71.9% of hospitals). However, there was considerable variability among the large teaching hospitals in their diversity (interquartile range of the numbers of commonly performed physiologically complex procedures = 19.3; lower 99% CL, 12.8 procedures). The diversity of procedures represents a substantive differentiator among hospitals. Thus, the usefulness of statistical methods for operating room management should be expected to be heterogeneous among hospitals. Our results also show that "large teaching hospital" alone is an insufficient description for accurate prediction of the extent to which a hospital sustains the

Health care reform debate includes discussions regarding outcomes of surgical interventions. Yet quality of medical care, when judged as a health outcome, is difficult to define because of impediments affecting accuracy in data collection, analysis, and reporting. In this prospective study, the authors report the outcomes for neurosurgical treatment based on point-of-care interactions recorded in the electronic medical record (EMR). The authors' neurosurgery practice collected outcome data for 19 physicians and ancillary personnel using the EMR. Data were analyzed for 5361 consecutive surgical cases, either elective or emergency procedures, performed during 2009 at multiple hospitals, offices, and an ambulatory spine surgery center. Main outcomes included complications, length of stay (LOS), and discharge disposition for all patients and for certain frequently performed procedures. Physicians, nurses, and other medical staff used validated scales to record the hospital LOS, complications, disposition at discharge, and return to work. Of the 5361 surgical procedures performed, two-thirds were spinal procedures and one-third were cranial procedures. Organization-wide compliance with reporting rates of major complications improved throughout the year, from 80.7% in the first quarter to 90.3% in the fourth quarter. Auditing showed that rates of unreported complications decreased from 11% in the first quarter to 4% in the fourth quarter. Complication data were available for 4593 procedures (85.7%); of these, no complications were reported in 4367 (95.1%). Discharge dispositions reported were home in 86.2%, rehabilitation center in 8.9%, and nursing home in 2.5%. Major complications included culture-proven infection in 0.61%, CSF leak in 0.89%, reoperation within the same hospitalization in 0.38%, and new neurological deficits in 0.77%. For the commonly performed procedures, the median hospital LOS was 3 days for craniotomy for aneurysm or intraaxial tumor and less than

To prospectively evaluate the ability of radio frequency detection (RFD) system-embedded sponges to mitigate the incidence of retained surgical sponges (RSS) after emergency surgery. Emergency surgery patients are at high risk for retained foreign bodies. All emergent trauma and nontrauma cavitary operations over a 5-year period (January 2010-December 2014) were prospectively enrolled. For damage-control procedures, only the definitive closure was included. RFD sponges were used exclusively throughout the study period. Before closure, the sponge and instrument count was followed by RFD scanning and x-ray evaluation for retained sponges. RSS and near-misses averted using the RFD system were analyzed. In all, 2051 patients [median (range)], aged 41 (1-101) years, 72.2% male, 46.8% trauma patients, underwent 2148 operations (1824 laparotomy, 100 thoracotomy, 30 sternotomy, and 97 combined). RFD detected retained sponges in 11 (0.5%) patients (81.8%laparotomy, 18.2% sternotomy) before cavitary closure. All postclosure x-rays were negative. No retained sponges were missed by the RFD system. Body mass index was 29 (23-43), estimated blood loss 1.0 L (0-23), and operating room time 160 minutes (71-869). Procedures started after 18:00 to 06:00 hours in 45.5% of the patients. The sponge count was incorrect in 36.4%, not performed due to time constraints in 45.5%, and correct in 18.2%. The additional cost of using RFD-embedded disposables was $0.17 for a 4X18 laparotomy sponge and $0.46 for a 10 pack of 12ply, 4X8. Emergent surgical procedures are high-risk for retained sponges, even when sponge counts are performed and found to be correct. Implementation of a RFD system was effective in preventing this complication and should be considered for emergent operations in an effort to improve patient safety.

Chronic pancreatitis (CP) is a painful, yet benign inflammatory process of the pancreas. Surgical management should be individualized because the pain is multifactorial and its mechanisms vary from patient to patient. Two main pathogenetic theories for the mechanisms of pain in CP have been proposed: the neurogenic theory and the theory of increased intraductal/intraparenchymal pressures. The latter theory is strongly supported by the good results of drainage procedures in the surgical management of CP. Other possible contributing factors include pancreatic ischemia; a centrally sensitized pain state; and the development of complications, such as pseudocysts and stenosis of the duodenum or common bile duct. Common indications for surgery include intractable pain, suspicion of neoplasm, and complications that cannot be resolved with radiological or endoscopic treatments. Operative procedures have been historically classified into 4 categories: decompression procedures for diseased and obstructed pancreatic ducts; resection procedures for the proximal, distal, or total pancreas; denervation procedures of the pancreas; and hybrid procedures. Pancreaticoduodenectomy and pylorus-preserving pancreaticoduodenectomy, once the standard operations for patients with CP, have been replaced by hybrid procedures, such as duodenum-preserving pancreatic head resection, the Frey procedure, and their variants. These procedures are safe and effective in providing long-term pain relief and in treating CP-related complications. Hybrid procedures should be the operations of choice for patients with CP.

Endoscopic therapy of acute and chronic pancreatitis has decreased the need for operative intervention. However, a significant proportion of patients treated endoscopically require definitive surgical management for persistent symptoms. Our aim was to determine which patients are likely to fail with endoscopic therapy, and to assess the clinical outcome of surgical management. Patients were identified using ICD-9 codes for pancreatic disease as well as CPT codes for endoscopic therapy followed by surgery. Patients with documented acute or chronic pancreatitis treated endoscopically prior to surgical therapy were included (N = 88). The majority of patients (65%) exhibited chronic pancreatitis due to alcohol abuse. Common indicators for surgery were: persistent symptoms, anatomy not amenable to endoscopic treatment and unresolved common bile duct or pancreatic duct strictures. Surgical salvage procedures included internal drainage of a pseudocyst or an obstructed pancreatic duct (46%), debridement of peripancreatic fluid collections (25%), and pancreatic resection (31%). Death occurred in 3% of patients. The most common complications were hemorrhage (16%), wound infection (13%), and pulmonary complications (11%). Chronic pancreatitis with persistent symptoms is the most common reason for pancreatic surgery following endoscopic therapy. Surgical salvage therapy can largely be accomplished by drainage procedures, but pancreatic resection is common. These complex procedures can be performed with acceptable mortality but also with significant risk for morbidity.

To maintain the health of service members and their families throughout the world, the Department of Defense has established several isolated military hospitals (IHs). The operational environment of IHs is such that illness and traumatic injury requiring surgical intervention is common. This study sought to examine the general and orthopedic surgical experience at an IH to determine whether surgical care could be provided in an effective and safe manner. All patients evaluated by the general and orthopedic surgeon at Guantanamo Bay Naval Hospital from October 1, 1998, to April 1, 1999, were included in this study. The following data were retrospectively reviewed: patient demographic data, diagnosis, initial and follow-up care, medical evacuation data, operative procedures, and complications. There were 336 patients who presented for surgical evaluation, resulting in 660 follow-up appointments during the study period. There were 31 medical evacuations (3 emergent). The surgical services performed 122 major operative procedures. There were 58 inpatient admissions. There was 1 death, and surgical complications occurred in 2 patients, for an overall morbidity and mortality of 1.4% and 0.7%, respectively. Our data show that an IH is capable of providing surgical care, including care for traumatic injuries, in a safe manner. This is the first study that provides objective evidence that general and orthopedic surgery at an IH can be provided within the standard of care.

Adaptation and innovation: a grounded theory study of procedural variation in the academic surgical workplace.

Surgical research struggles to describe the relationship between procedural variations in daily practice and traditional conceptualizations of evidence. The problem has resisted simple solutions, in part, because we lack a solid understanding of how surgeons conceptualize and interact around variation, adaptation, innovation, and evidence in daily practice. This grounded theory study aims to describe the social processes that influence how procedural variation is conceptualized in the surgical workplace. Using the constructivist grounded theory methodology, semi-structured interviews with surgeons (n = 19) from four North American academic centres were collected and analysed. Purposive sampling targeted surgeons with experiential knowledge of the role of variations in the workplace. Theoretical sampling was conducted until a theoretical framework representing key processes was conceptually saturated. Surgical procedural variation was influenced by three key processes. Seeking improvement was shaped by having unsolved procedural problems, adapting in the moment, and pursuing personal opportunities. Orienting self and others to variations consisted of sharing stories of variations with others, taking stock of how a variation promoted personal interests, and placing trust in peers. Acting under cultural and material conditions was characterized by being wary, positioning personal image, showing the logic of a variation, and making use of academic resources to do so. Our findings include social processes that influence how adaptations are incubated in surgical practice and mature into innovations. This study offers a language for conceptualizing the sociocultural influences on procedural variations in surgery. Interventions to change how surgeons interact with variations on a day-to-day basis should consider these social processes in their design. © 2015 John Wiley & Sons, Ltd.

Primary hyperparathyroidism (PHPT) is the most common cause of hypercalcaemia in outpatients. It is more common in females, after menopause, and the prevalence is 1 to 4:1000 in the general population. Patients with PHPT have abnormal regulation of PTH secretion, resulting in elevated serum calcium and inappropriately high or normal PTH in relation to the calcium value. Sporadic PTH-secreting adenoma alone accounts for 90% of cases of PHPT, while multiglandular hyperplasia is more common in familial hyperparathyroidism syndromes (5%) and parathyroid carcinomas represent less than 1% of cases. Only after making sure there is functional autonomy of one or more parathyroid glands, localization imaging tests should be performed to guide a possible surgical procedure. It is important to highlight that these tests have limitations and can yield false-positive and false-negative results. There are cases in which the parathyroid gland is difficult to be located, requiring a combination of imaging methods for pre-operative localization, such as {sup 99m}Tc-pertechnetate, SPECT, SPECT/CT, and US. We describe the case of a 50-year-old female patient diagnosed with PHPT, who underwent a surgical procedure without success, with maintenance of hypercalcaemia and hyperparathyroidism. In this case, the hyper functioning parathyroid was located in the retrotracheal region only after scintigraphy combined with SPECT/CT were used. (author)

The effect of surgical complications on hospital finances is unclear. To determine the relationship between major surgical complications and per-encounter hospital costs and revenues by payer type. Retrospective analysis of administrative data for all inpatient surgical discharges during 2010 from a nonprofit 12-hospital system in the southern United States. Discharges were categorized by principal procedure and occurrence of 1 or more postsurgical complications, using International Classification of Diseases, Ninth Revision, diagnosis and procedure codes. Nine common surgical procedures and 10 major complications across 4 payer types were analyzed. Hospital costs and revenue at discharge were obtained from hospital accounting systems and classified by payer type. Hospital costs, revenues, and contribution margin (defined as revenue minus variable expenses) were compared for patients with and without surgical complications according to payer type. Of 34,256 surgical discharges, 1820 patients (5.3%; 95% CI, 4.4%-6.4%) experienced 1 or more postsurgical complications. Compared with absence of complications, complications were associated with a $39,017 (95% CI, $20,069-$50,394; P financial consequences for decreasing postsurgical complications.

Haematocrit has been studied as an outcome predictor. The aim of this study was to evaluate the correlation between low haematocrit at surgical intensive care unit admission and high disease scoring system score and early outcomes. This retrospective study included 4398 patients admitted to the surgical intensive care unit between January 2006 and July 2013. Acute physiology and chronic health evaluation and simplified acute physiology score II values were calculated and all variables entered as parameters were evaluated independently. Patients were classified as haematocrit if they had a haematocrit < 30% at surgical intensive care unit admission. The correlation between admission haematocrit and outcome was evaluated by univariate analysis and linear regression. A total of 1126 (25.6%) patients had haematocrit. These patients had higher rates of major cardiac events (4% vs 1.9%, p < 0.001), acute renal failure (11.5% vs 4.7%, p < 0.001), and mortality during surgical intensive care unit stay (3% vs 0.8%, p < 0.001) and hospital stay (12% vs 5.9%, p < 0.001). A haematocrit level < 30% at surgical intensive care unit admission was frequent and appears to be a predictor for poorer outcome in critical surgical patients. Patients with haematocrit had longer surgical intensive care unit and hospital stay lengths, more postoperative complications, and higher surgical intensive care unit and hospital mortality rates.

The authors present a new procedure of computer-assisted genioplasty. They determined the anterior, posterior and inferior limits of the chin in relation to the skull and face with the newly developed and validated three-dimensional cephalometric planar analysis (ACRO 3D). Virtual planning of the osteotomy lines was carried out with Mimics (Materialize) software. The authors built a three-dimensional rapid-prototyping multi-position model of the chin area from a medical low-dose CT scan. The transfer of virtual information to the operating room consisted of two elements. First, the titanium plates on the 3D RP model were pre-bent. Second, a surgical guide for the transfer of the osteotomy lines and the positions of the screws to the operating room was manufactured. The authors present the first case of the use of this model on a patient. The postoperative results are promising, and the technique is fast and easy-to-use. More patients are needed for a definitive clinical validation of this procedure. Copyright 2010 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

Surgical site infections (SSIs) occur at an average rate of 21.1 per cent after Whipple procedures per NSQIP data. In the setting of adherence to standard National Surgery Quality Improvement Program (NSQIP) Hepatopancreatobiliary recommendations including wound protector use and glove change before closing, this study seeks to evaluate the efficacy of using negative pressure wound treatment (NPWT) over closed incision sites after a Whipple procedure to prevent SSI formation. We retrospectively examined consecutive patients from January 2014 to July 2016 who met criteria of completing Whipple procedures with full primary incision closure performed by a single surgeon at a single institution. Sixty-one patients were included in the study between two cohorts: traditional dressing (TD) (n = 36) and NPWT dressing (n = 25). There was a statistically significant difference (P = 0.01) in SSI formation between the TD cohort (n = 15, SSI rate = 0.41) and the NPWT cohort (n = 3, SSI rate = 0.12). The adjusted odds ratio (OR) of SSI formation was significant for NPWT use [OR = 0.15, P = 0.036] and for hospital length of stay [OR = 1.21, P = 0.024]. Operative length, operative blood loss, units of perioperative blood transfusion, intraoperative gastrojejunal tube placement, preoperative stent placement, and postoperative antibiotic duration did not significantly impact SSI formation (P > 0.05).

The aim of this study is to evaluate the efficacy of emergency percutaneous treatment in patients with surgical bile duct injury (SBDI). From May 2004 to May 2007, 11 patients (five men, six women; age range 26-80 years; mean age 58 years) with a critical clinical picture (severe jaundice, bile peritonitis, septic state) due to SBDI secondary to surgical or laparoscopic procedures were treated by percutaneous procedures. We performed four ultrasound-guided percutaneous drainages, four external-internal biliary drainages, one bilioplasty, and two plastic biliary stenting after 2 weeks of external-internal biliary drainage placement. All procedures had 100% technical success with no complications. The clinical emergencies resolved in 3-4 days in 100% of cases. All patients had a benign clinical course, and reoperation was avoided in 100% of cases. Interventional radiological procedures are effective in the emergency management of SBDI since they are minimally invasive and have a high success rate and a low incidence of complications compared to the more complex and dangerous surgical or laparoscopic options.

Full Text Available Background: Patients who had received surgical services at Bellin Hospital reported anxiety with the surgical flow. This study tested the hypothesis that the introduction of a surgical navigator, someone who guided the patient and their accompanying others throughout the surgical process, would improve patient satisfaction. Methods: Ambulatory surgical patients were randomized to control and study groups. The study group patients were assigned a surgical navigator. Prior to discharge from the hospital, patients were asked to complete a patient satisfaction survey. Results: The study group had significantly higher mean scores (P value ≤ 0.026, top box scores (P value ≤ 0.021, and positive comments. Conclusion: The addition of a surgical navigator to the perioperative process significantly enhanced patient satisfaction in ambulatory surgical patients.

All these developments aim to cause as little trauma as possible to the eye, to safely, effectively, and sustainably reduce intraocular pressure (IOP, to produce reproducible results, and to be easy to adopt. The term “micro-invasive glaucoma surgery (MIGS” was used for summarizing all these procedures. Currently MIGS is gaining more and more interest and popularity. The possible reduction of the number of glaucoma medications, the ab interno approach without damaging the conjunctival tissue, and the probably safer procedures compared to incisional surgical methods may explain the increased interest in MIGS. The use of glaucoma drainage implants for lowering IOP in difficult-to-treat patients has been established for a long time, however, a variety of new glaucoma micro-stents are being manufactured by using various materials and are available to increase aqueous outflow via different pathways. This review summarizes published results of randomized clinical studies and extensive case report series on these devices, including Schlemm’s canal stents (iStent®, iStent® inject, Hydrus, suprachoroidal stents (CyPass®, iStent® Supra, and subconjunctival stents (XEN. The article summarizes the findings of published material on efficacy and safety for each of these approaches.

CT was performed on 80 patients with recurrent symptoms of chronic sinusitis after Caldwell-Luc and/or nasoantral window procedures. In each case there was anterior ethmoid sinus inflammatory disease with obstruction of the normal ipsilateral maxillary sinus drainage, the ostiomeatal unit. When the ipsilateral frontal sinus was also diseased, the anterior ethmoid sinus inflammatory process was found to block the frontal recess. These findings indicate that patients who have chronic sinusitis after Caldwell-Luc and/or nasoantral window procedures fail because of persistent disease. The disease is characteristically situated in the anterior ethmoid cells, with blockage of mucociliary clearance from the maxillary and frontal sinuses. Therefore, the cure is predicated on surgical procedures directed to restoring patency of the ostiomeatal unit and frontal recess

Objective A quality improvement initiative was employed to decrease single institution surgical site infection rate in open lower extremity revascularization procedures. In an attempt to lower patient morbidity, we developed and implemented the Preventative Surgical Site Infection Protocol in Vascular Surgery. Surgical site infections lead to prolonged hospital stays, adjunctive procedure, and additive costs. We employed targeted interventions to address the common risk factors that predispose patients to post-operative complications. Methods Retrospective review was performed between 2012 and 2016 for all surgical site infections after revascularization procedures of the lower extremity. A quality improvement protocol was initiated in January 2015. Primary outcome was the assessment of surgical site infection rate reduction in the pre-protocol vs. post-protocol era. Secondary outcomes evaluated patient demographics, closure method, perioperative antibiotic coverage, and management outcomes. Results Implementation of the protocol decreased the surgical site infection rate from 6.4% to 1.6% p = 0.0137). Patient demographics and comorbidities were assessed and failed to demonstrate a statistically significant difference among the infection and no-infection groups. Wound closure with monocryl suture vs. staple proved to be associated with decreased surgical site infection rate ( p site infections in the vascular surgery population are effective and necessary. Our data suggest that there may be benefit in the incorporation of MRSA and Gram-negative coverage as part of the Surgical Care Improvement Project perioperative guidelines.

To report the changes in patient-reported quality of life for women undergoing gynecologic oncology surgeries. In a prospective cohort study from 10/2013-10/2014, women were enrolled pre-operatively and completed comprehensive interviews at baseline, 1, 3, and 6months post-operatively. Measures included the disease-specific Functional Assessment of Cancer Therapy-General (FACT-GP), general Patient Reported Outcome Measure Information System (PROMIS) global health and validated measures of anxiety and depression. Bivariate statistics were used to analyze demographic groups and changes in mean scores over time. Of 231 patients completing baseline interviews, 185 (80%) completed 1-month, 170 (74%) 3-month, and 174 (75%) 6-month interviews. Minimally invasive (n=115, 63%) and laparotomy (n=60, 32%) procedures were performed. Functional wellbeing (20 → 17.6, ptherapy administration. In an exploratory analysis of the interaction of QOL and quality, patients with increased postoperative healthcare resource use were noted to have higher baseline levels of anxiety. For women undergoing gynecologic oncology procedures, temporary declines in functional wellbeing are balanced by improvements in emotional wellbeing and decreased anxiety symptoms after surgery. Not all commonly used QOL surveys are sensitive to changes during the perioperative period and may not be suitable for use in surgical quality metrics. Copyright © 2016 Elsevier Inc.

Acute bacterial endocarditis continues to be a condition with high morbidity. Although the majority of patients are treated by high-dose antibiotics, a high-risk patient group requires surgical intervention, which is the subject of this article. From 1972 to 1991, 3,820 patients underwent heart valve replacement at the Brigham and Women's Hospital, Boston. Of this group, 158 patients underwent surgery for acute bacterial endocarditis: 109 had native valve endocarditis (NVE), and 49 had prosthetic valve endocarditis (PVE). There were 108 men and 50 women with a mean age of 49 years (range, 16-79 years); 64% were New York Heart Association functional class IV before surgery, and 12% of the group had a history of intravenous drug abuse. In both NVE and PVE groups, Streptococcus was the predominant infecting agent. Uncontrolled sepsis, progressive congestive failure, peripheral emboli, and echocardiographically demonstrated vegetations were the most common indications for surgery. Eighty-five percent of patients had a single-valve procedure, 15% had a multivalve procedure, and 34 patients had other associated major cardiac procedures. The operative mortality was 6% in NVE and 22% in PVE. Long-term survival at 10 years was 66% for NVE and 29% for PVE. Freedom from recurrent endocarditis at 10 years was 85% for NVE and 82% for PVE. The main factors associated with decreased survival overall were PVE and nonstreptococcal infection. The morbidity and mortality after surgical treatment of acute endocarditis depend on the site, the severity, and the subject infected. Early aggressive surgical intervention is indicated to optimize surgical results, especially in patients with nonstreptococcal infection or PVE.

Full Text Available Introduction: Stress urinary incontinence is a highly debilitating condition, with an important impact over the quality of life. When the conservative treatment fails, the surgical treatment is a viable solution. Minimally invasive sling procedures have become the gold standard of surgical management for stress urinary incontinence (SUI in women. Material and methods: The study was conducted on 68 patients with stress urinary incontinence, 52 have undergone the retropubic tension-free vaginal tape and 16 patients were operated using the transobturator tape procedure. All the patients were evaluated before the operation and the indication of the surgical treatment was established on the basis of physical examination (all the patients had positive cough test, abdominal ultrasound (to determine postvoid residual urine volume, urinalysis and urine culture (the majority of the patients have had before the operation recurrent urinary tract infections. Results: The satisfaction was similar in both groups of patients, with an average satisfaction rate of 91% for TVT and 86% for the patients who have undergone TOT procedure. The patients were in a proportion of 78,9% at menopause, with an average number of natural births of 1.9 and a mean BMI of 28.2. Regarding the surgical duration, this has varied between 20 and 40 minutes, being higher in the TVT cases (up to 5-7 minutes longer than TOT, because cystoscopy was performed during the operation to verify if the bladder was perforated or not. The urethral catheter was removed immediately after the operation in the case of the TOT procedure and in the day after the operation for the patients who have undergone TVT procedures (all of these patients associated genital prolapse. The hospitalization time was 3 days. We haven’t encountered significant intraoperative and postoperative complications. Conclusions: The TOT and TVT procedures have proven to be highly effective and safe methods in the treatment of

Objective To assess the safety and effectiveness of the endoscopic endonasal transsphenoidal approach (EETA) for apoplectic pituitary adenoma. Design A retrospective study. Setting Qilu Hospital of Shandong University; Brain Science Research Institute, Shandong University. Participants Patients admitted to Qilu Hospital of Shandong University who were diagnosed with an apoplectic pituitary tumor and underwent EETA for resection of the tumor. Main Outcome Measures In total 45 patients were included in a retrospective chart review. Data regarding patient age, sex, presentation, lesion size, surgical procedure, extent of resection, clinical outcome, and surgical complications were obtained from the chart review. Results In total, 38 (92.7%) of 41 patients with loss of vision obtained visual remission postoperatively. In addition, 16 patients reported a secreting adenoma, and postsurgical hormonal levels were normal or decreased in 14 patients. All other symptoms, such as headache and alteration of mental status, recovered rapidly after surgery. Two patients (4.4%) incurred cerebrospinal fluid leakage. Six patients (13.3%) experienced transient diabetes insipidus (DI) postoperatively, but none of these patients developed permanent DI. Five patients (11.1%) developed hypopituitarism and were treated with replacement of hormonal medicine. No cases of meningitis, carotid artery injury, or death related to surgery were reported. Conclusion EETA offers a safe and effective surgical option for apoplectic pituitary tumors and is associated with low morbidity and mortality.

The tracheostomy is a frequently used procedure for the respiratory weaning of ventilated patients allows sedation free ECLS use in awake patient. The aim of this study is to assess the possibility and highlight the benefits of lowering the impact of sedation in surgical non-transplant patients on ECLS. The specific objective was to investigate the use of tracheostomy as a bridge to spontaneous breathing on ECLS. Of the 95 patients, 65 patients received a tracheostomy, and 5 patients were admitted with a tracheostoma. One patient was cannulated without intubation, one is extubated during ECLS course after 48 hours. 4 patients were extubated after weaning and the removal of ECLS. 19 patients died before the indication to tracheostomy was given. Tracheostomy can bridge to spontaneous breathing and awake-ECMO in non-transplant surgical patients. The "awake ECMO" strategy may avoid complications related to mechanical ventilation, sedation, and immobilization and provide comparable outcomes to other approaches for providing respiratory support. © 2017 The Authors.

Because of the increasing number of interventional endovascular procedures with fluoroscopy and the corresponding high annual dose for interventionalists, additional dose-protecting measures are desirable. The purpose of this study was to evaluate the effect of disposable radiation-absorbing surgical drapes in reducing scatter radiation exposure for interventionalists and supporting staff during an endovascular aneurysm repair (EVAR) procedure. This was a randomized control trial in which 36 EVAR procedures were randomized between execution with and without disposable radiation-absorbing surgical drapes (Radpad: Worldwide Innovations & Technologies, Inc., Kansas City, US, type 5511A). Dosimetric measurements were performed on the interventionalist (hand and chest) and theatre nurse (chest) with and without the use of the drapes to obtain the dose reduction and effect on the annual dose caused by the drapes. Use of disposable radiation-absorbing surgical drapes resulted in dose reductions of 49%, 55%, and 48%, respectively, measured on the hand and chest of the interventionalist and the chest of the theatre nurse. The use of disposable radiation-absorbing surgical drapes significantly reduces scatter radiation exposure for both the interventionalist and the supporting staff during EVAR procedures.

Background It is generally accepted that surgical training is associated with increased surgical duration. The purpose of this study was to determine the magnitude of this increase for common surgical procedures by comparing surgery duration in teaching and nonteaching hospitals. Methods This retrospective population-based cohort study included all adult residents of Ontario, Canada, who underwent 1 of 14 surgical procedures between 2002 and 2012. We used several linked administrative databases to identify the study cohort in addition to patient-, surgeon- and procedure-related variables. We determined surgery duration using anesthesiology billing records. Negative binomial regression was used to model the association between teaching versus nonteaching hospital status and surgery duration. Results Of the 713 573 surgical cases included in this study, 20.8% were performed in a teaching hospital. For each procedure, the mean surgery duration was significantly longer for teaching hospitals, with differences ranging from 5 to 62 minutes across individual procedures in unadjusted analyses (all p surgery duration, adjusting for patient-, surgeon- and procedure-related variables as well as the clustering of patients within surgeons and hospitals. Conclusion Our results show that a wide range of surgical procedures require significantly more time to perform in teaching than nonteaching hospitals. Given the magnitude of this difference, the impact of surgical training on health care costs and clinical outcomes should be a priority for future studies. PMID:27007088

However, few information is available emphasizing changes in language after aneurismal SAH and aneurysm location influence. Objective To assess the language and verbal fluency performance in aneurismal SAH pre- and post-surgery in patients caused by an aneurysm of the anterior communicating artery (AcomA, left middle cerebral artery (L-MCA and left posterior comunicating artery (L-PcomA. Methods Assessment in 79 patients with SAH, on two occasions: pre- and post surgical treatment. They were divided into three groups by the aneurysms’ location. Results Deterioration is detected in the performance of all patients during the post-surgical period; L-MCA aneurysm patients displayed a reduction in verbal naming and fluency; L-PcomA patients deteriorated in the written language and fluency tasks. Conclusion After the surgical procedure the patients decreased in various language tasks and these differences in performance being directly related to the location of the aneurysm.

Background: Hemorrhages, cerebrospinal fluid (CSF) fistula and infections are the most challenging postoperative complications in Neurosurgery. In this study, we report our preliminary results using a fully autologous fibrin sealant agent, the Vivostat® system, in achieving hemostasis and CSF leakage repair during cranio-cerebral procedures. Methods: From January 2012 to March 2014, 77 patients were studied prospectively and data were collected and analyzed. Autologous fibrin sealant, taken from patient's blood, was prepared with the Vivostat® system and applied on the resection bed or above the dura mater to achieve hemostasis and dural sealing. The surgical technique, time to bleeding control and associated complications were recorded. Results: A total of 79 neurosurgical procedures have been performed on 77 patients. In the majority of cases (98%) the same autologous fibrin glue provided rapid hemostasis and dural sealing. No patient developed allergic reactions or systemic complications in association with its application. There were no cases of cerebral hematoma, swelling, infection, or epileptic seizures after surgery whether in the immediate or in late period follow-up. Conclusions: In this preliminary study, the easy and direct application of autologous fibrin sealant agent helped in controlling cerebral bleeding and in providing prompt and efficient dural sealing with resolution of CSF leaks. Although the use of autologous fibrin glue seems to be safe, easy, and effective, further investigations are strongly recommended to quantify real advantages and potential limitations. PMID:25984391

Although having a large diversity of types of procedures has a substantial operational impact on the surgical suites of hospitals, the strategic importance is unknown. In the current study, we used longitudinal data for all hospitals and patient ages in the State of Florida to evaluate whether hospitals with greater diversity of types of physiologically complex major therapeutic procedures (PCMTP) also had greater rates of surgical growth. Observational cohort study. 1479 combinations of hospitals in the State of Florida and fiscal years, 2008-2015. The types of International Classification of Diseases, Ninth revision, Clinical Modification (ICD-9-CM) procedures studied were PCMT, defined as: a) major therapeutic procedure; b) >7 American Society of Anesthesiologists base units; and c) performed during a hospitalization with a Diagnosis Related Group with a mean length of stay ≥4.0days. The number of procedures of each type of PCMTP commonly performed at each hospital was calculated by taking 1/Herfindahl index (i.e., sum of the squares of the proportions of all procedures of each type of PCMTP). Over the 8 successive years studied, there was no change in the number of PCMTP being performed (Kendall's τ b =-0.014±0.017 [standard error], P=0.44; N=1479 hospital×years). Busier and larger hospitals commonly performed more types of PCMTP, respectively categorized based on performed PCMTP (τ=0.606±0.017, P<0.0001) or hospital beds (τ=0.524±0.017, P<0.0001). There was no association between greater diversity of types of PCMTP commonly performed and greater annual growth in numbers of PCMTP (τ=0.002±0.019, P=0.91; N=1295 hospital×years). Conclusions were the same with multiple sensitivity analyses. Post hoc, it was recognized that hospitals performing a greater diversity of PCMTP were more similar to the aggregate of other hospitals within the same health district (τ=0.550±0.017, P<0.0001). During a period with no overall growth in PCMTP, hospitals with

Objective. To describe the effects of surgical treatment and complications in 46 patients with carotid body tumor (CBT). Method. Retrospective study on surgical treatment and complications was carried out in 46 cases of CBT which were surgically treated with different kind of procedures. Result. All procedures performed successfully except that the CBT was not excised in 4 cases. No operative mortality was observed. There were 2 postoperative hemiplegia, 4 hypoglossal nerve impairment,2 glossopharyngeal nerve impairment, 1 vagus nerve impairment, and 1 accessory nerve impairment. One patient presented postoperative cranial nerve impairment in glossopharyngeal, vagus and hypoglossal nerves. Two patients developed local recurrence during the long-term follow-up. Conclusion. Complete surgical excision was possible in each patient if the diagnosis had been correctly made through selective preoperative angiography, vessel ultrasound Doppler and other examinations.Reasonable surgical procedure and Matas training were necessary to the successful surgical treatment and thus decrease the complicative incidence rate of carotid chemodectomas.

A women with Philadelphia chromosome-positive chronic myelocytic leukemia lived nearly 12 years from the time of diagnosis. During most of this period she received no therapy, and marked cyclic oscillations in the white blood cell count were documented. The last two years of her illness were marked by a hemorrhagic disorder associated with hypofibrinogenemia, thrombocytopenia, increased plasma fibrinopeptide A concentration and markedly elevated serum levels of fibrin degradation products. The coagulation disorder was rapidly reversible on several occasions with heparin therapy. After treatment with heparin and platelet transfusions, the patient underwent successful resection of a large ovarian cyst with excellent hemostasis during the procedure. Postoperatively, the administration of heparin and platelets was discontinued and a large wound hematoma developed. After resumption of therapy with heparin and platelets, the remainder of her postoperative course was uneventful. The literature on the subject is reviewed and tentative guidelines are offered concerning the management of patients with intravascular coagulation who require diagnostic or therapeutic surgical procedures.

Burr-hole trephine and insertion of an external ventricular drainage (EVD) is a common procedure in neurosurgical practice. In critically ill patients, the transport to the operating room, OR represents a major risk. Thus, the burr-hole trephine and implantation of an EVD is frequently performed on the Intensive Care Unit (ICU). Since 2004, we have applied two different procedures: the conventional method with a mechanical compressed air or an electric drill, and an alternative method with a manual twist drill, including fixation of the EVD in a skull screw (Bolt Kit, Raumedic AG, Germany). This study was designed to evaluate the outcome of both surgical procedures. In this retrospective analysis we included 166 consecutive patients with acute hydrocephalus due to intracranial hemorrhage that had been operated at our neurosurgical ICU in a six years interval. We reviewed the charts for gender and age, kind of surgical procedure, cerebrospinal fluid (CSF)-infections, duration of drainage, attempts of insertions, wound infections, misplacement rate, post-surgical hemorrhages, revisions, comorbidities and shunt-dependency. In 122 patients we applied the Bolt Kit System, in 44 patients the conventional method was performed. We found a significantly lower rate of CSF-infections and significantly fewer attempts of insertions in the Bolt Kit group (p = 0.002 and p = 0.001, respectively). The rate of wound infections, misplacement, revisions, shunt-dependency and the post-surgical hemorrhages did not differ significantly. Our data indicate that the manual drill and the skull screw are safe and feasible tools in the treatment of acute hydrocephalus. Presumably, the direct skin contact is causative for the higher rate of CSF-infections when the conventional method is performed. The skull screw guides the EVD into the ventricle without skin contact. The lower number of insertions needed may be due to the fact that the skull screw allows just one trajectory for the insertion

In elderly, high-risk surgical patients, sutureless aortic valve replacement (AVR) can often be an alternative to conventional AVR; shorter aortic cross-clamp and cardiopulmonary bypass times are the chief advantages. We compared the outcomes of sutureless AVR with those of conventional AVR in 70 elderly patients who underwent concomitant cardiac surgical procedures. We retrospectively analyzed the cases of 42 men and 28 women (mean age, 70.4 ± 10.3 yr; range, 34-93 yr) who underwent cardiac operations plus AVR with either a sutureless valve (group 1, n=38) or a conventional bioprosthetic or mechanical valve (group 2, n=32). Baseline patient characteristics were similar except for worse New York Heart Association functional status and the prevalence of diabetes mellitus in group 1. In group 1, the operative, cross-clamp, and cardiopulmonary bypass times were shorter (all P =0.001), postoperative drainage amounts were lower ( P =0.009), hospital stays were shorter ( P =0.004), and less red blood cell transfusion was needed ( P =0.037). Echocardiograms before patients' discharge from the hospital showed lower peak and mean aortic gradients in group 1 (mean transvalvular gradient, 8.4 ± 2.8 vs 12.2 ± 5.2 mmHg; P =0.012). We found that elderly, high-risk patients who underwent multiple cardiac surgical procedures and sutureless AVR had better hemodynamic outcomes and shorter ischemic times than did patients who underwent conventional AVR.

Additional use of the video-assisted thoracoscopic surgery (VATS) technique in the Nuss procedure has been globally accepted for the improvement of safety of surgical treatment as well as for decreased frequency of serious intraoperative and postoperative complications. To evaluate VATS in surgical treatment of patients with pectus excavatum by the left-to-right Nuss procedure for prevention of serious intra- and postoperative complications. From 2002 to 2016, 1006 patients with pectus excavatum aged 7 to 62 years (mean: 18.6) underwent the Nuss procedure. There were 796 males and 210 females. The clinical records of all patients were analyzed retrospectively. The follow-up varied from 1 to 172 months (mean: 80.7 ±43). The early 30-day postoperative mortality was zero. Early thoracoscopy-dependent postoperative complications, the majority transient and non-life-threatening, occurred in 35.6% of patients. The most frequent complication was pneumothorax, diagnosed in 24.5% of patients. Two patients required repeat surgery. One patient required VATS pleurectomy due to persistent postoperative air leakage. In another patient left thoracotomy following bleeding from the pleural cavity was performed. The use of VATS in the left-to-right Nuss procedure for pectus excavatum ensures the safety of surgical treatment and minimizes the occurrence of serious intra- and postoperative complications concerning injury of the mediastinum, lung, diaphragm or abdominal cavity.

The goal of this study is to evaluate the pure impact of the revision of surgical fee schedule on surgeons' productivity. We collected data from the surgical procedures performed by the surgeons working in Teikyo University Hospital from 1 April through 30 September in 2013-2016. We employed non-radial and non-oriented Malmquist model. We defined the decision-making unit as a surgeon with the highest academic rank in surgery. Inputs were defined as (1) the number of doctors who assisted surgery and (2) the time of surgical operation. The output was defined as the surgical fee for each surgery. We focused on the revisions in 2014 and 2016. We first calculated each surgeon's natural logarithms of the changes in productivity, technique and efficiency in 2013-2014, in 2014-2015 and in 2015-2016. Then, we subtracted the changes in 2014-2015 from the changes in 2013-2014 and in 2015-2016. We analyzed 62 surgeons who performed 7602 surgical procedures. The productivity changes were not significantly different from 0. Their efficiency change was significantly greater than 0, while their technical change was smaller than 0 in revision 2014. Their efficiency change was significantly smaller than 0, while their technical change was greater than 0 in revision 2016 (p increase overall productivity through revision if we could increase both efficiency and technique.

The diagnostic accuracy of biliary scanning using /sup 99m/Tc-pyridoxylideneglutamate has been determined in a series of 51 surgically jaundiced patients. This noninvasive technique was found to be safe, reliable and universally applicable in all instances of jaundice, regardless of the serum bilirubin value or prothrombin time. The results were found to compare favorably with those of other investigative procedures. It is suggested that the /sup 99m/Tc-pyridoxylideneglutamate biliary scan is most advantageously carried out after clinical assessment and full biochemical evaluation of the patient. The scan result will indicate the next logical step in the management of the patient whether it be endoscopic retrograde cholangiopancreatography, percutaneous transhepatic cholangiography, biopsy of the liver or laparotomy

Scalp flora in Indian patients undergoing craniotomy for brain tumors - Implications for pre-surgical site preparation and surgical site infection

Directory of Open Access Journals (Sweden)

Aliasgar V Moiyadi

2012-01-01

Full Text Available Introduction: Causation of surgical site infection (SSI following craniotomy is multifactorial. Most preventive strategies (including site preparation and antibiotic prophylaxis revolve around reducing preoperative contamination of the local site. There is little evidence, however, linking site contamination with postoperative infections. This is important given the preference for performing non-shaved cranial surgery. We undertook a prospective study to document the scalp flora in neurosurgical patients in an Indian setting and to assess possible association with SSI. Materials and Methods: A prospective study recruited 45 patients undergoing non-shaved clean craniotomies for various brain tumors. Standard perioperative procedures and antibiotic policy were employed. Prior to and immediately following the pre-surgical scrubbing, we collected swabs and evaluated their growth qualitatively. SSI was documented adhering to CDC guidelines. The association of swab-positivity with various parameters (including SSI was evaluated. Results: Pre-scrub positivity was seen in 18 of 44 patients, three of them developed subsequent SSI. Most were known skin contaminants. Five patients had swab positivity after scrubbing, though none of these developed any SSI. Four of these five had pre-scrub positivity. In three the same organisms persisted (two being Staphylococcus aureus, and one had different growth post-scrub, whereas one patient developed new growth (contaminant mycelial fungus in the post-scrub swab. We did not find any association between swab positivity and SSI. Swab positivity was also not related to hair-length or hygiene. Conclusion: Scalp flora in Indian patients is similar to that described. Pre-surgical preparation does not always eliminate this contamination (especially staphylococcus. However, this does not necessarily translate into increased SSI. Moreover, the results also provide objective evidence to support the performance of non

An analysis of treatment of 584 patients with complicated forms of chronic pancreatitis operated during 2000-2100 years was carried out. Quality of life of postoperative patients was estimated according to a technique of calculations of modules EORTC QLQ-C30 and EORTC QLQ-PAN26. The indicators of quality of life have improved by 19.7% in performance of saving duodenal outflow of operations of pancreatic juice. Change of the surgical strategy has led to decreased number of postoperative complications by 4.6% and to satisfactory long-term results in 92.6% of the patients.

Bresadola, Vittorio; Feo, Carlo V

2012-04-01

Achalasia is a rare disease of the esophagus, characterized by the absence of peristalsis in the esophageal body and incomplete relaxation of the lower esophageal sphincter, which may be hypertensive. The cause of this disease is unknown; therefore, the aim of the therapy is to improve esophageal emptying by eliminating the outflow resistance caused by the lower esophageal sphincter. This goal can be accomplished either by pneumatic dilatation or surgical myotomy, which are the only long-term effective therapies for achalasia. Historically, pneumatic dilatation was preferred over surgical myotomy because of the morbidity associated with a thoracotomy or a laparotomy. However, with the development of minimally invasive techniques, the surgical approach has gained widespread acceptance among patients and gastroenterologists and, consequently, the role of surgery has changed. The aim of this study was to review the changes occurred in the surgical treatment of achalasia over the last 2 decades; specifically, the development of minimally invasive techniques with the evolution from a thoracoscopic approach without an antireflux procedure to a laparoscopic myotomy with a partial fundoplication, the changes in the length of the myotomy, and the modification of the therapeutic algorithm.

Abstract Although percutaneous dilatational tracheostomy (PDT) is more accessible and less time-demanding compared with surgical tracheostomy (ST), it has its own limitations. We introduced a modified PDT technique and brought some surgical knowledge to the bedside to overcome some standard percutaneous dilatational tracheostomy relative contraindications. PDT uses a blind route of tracheal access that usually requires perioperational imaging guidance to protect accidental injuries. Moreover, there are contraindications in certain cases, limiting widespread PDT application. Different PDT modifications and devices have been represented to address the problem; however, these approaches are not generally popular among professionals due to limited accessibility and/or other reasons. We prospectively analyzed the double-blinded trial, patient and nurse head evaluating the complications, and collected data from 360 patients who underwent PDT, ST, or our modified mini-surgical PDT (msPDT, Hashemian method). These patients were divided into 2 groups—contraindicated to PDT—and randomization was done for msPDT or PDT in PDT-indicated group and msPDT or ST for PDT-contraindicated patients. The cases were compared in terms of pre and postoperational complications. Data analysis demonstrated that the mean value of procedural time was significantly lower in the msPDT group, either compared with the standard PDT or the ST group. Paratracheal insertion, intraprocedural hypoxemia, and bleeding were also significantly lower in the msPDT group compared with the standard PDT group. Other complications were not significantly different between msPDT and ST patients. The introduced msPDT represented a semiopen incision, other than blinded PDT route of tracheal access that allowed proceduralist to withdraw bronchoscopy and reduced the total time of procedure. Interestingly, the most important improvement was performing msPDT on PDT-contraindicated patients with the complication rate

In a series of 103 cases of postirradiation lesions of the brachial plexus operated on between 1978 and 1986--of which 60 patients have been reviewed with a follow up from 2 to 9 years--the surgical results are analyzed according to an anatomic classification, a clinical classification, and the surgical procedures. We conclude that the radiation plexitis should be treated surgically and at the earliest possible time after the onset of paresthesias. Also, the surgical procedure which gives the best results is neurolysis with pedicled omentoplasty

Full Text Available Background. The aim of this paper is to present and assess a surgical treatment of patients with colon cancer.Methods. All patients with colon cancer, who were operated in years 1998–2001, were included in the analysis. We have collected data including patients age, localization and stage of cancer, types of preformed procedures, postoperative mortality, disease recurrence and survival of the patients.Results. We have operated on 308 patients with histological evidence of colon cancer in abovementioned period. The average patients age was 66.5 years (SD = 11.1; 95% CI: 44.3– 88.7. Primary tumor was most commonly (36% located in sigmoid colon. UICC stages were as follows: stage I 34 patients, 11%; stage II 141, 46%; stage III 64, 21%; stage IV 69, 22%. We have performed 287 resections of colon (93% resectabillity, of these 214 (75% were potentially curative R0 resections. Share of urgent procedures was 21%. In the postoperative period 22 patients (7% have died. Postoperative mortality was significantly higher by urgent (19% compared to scheduled procedures (4% ( χ 2 = 16; df = 1; p = 0,005. In the observed time 22% of patients developed recurrent cancer. Mean survival rate of our patients was 1274 days or 3.5 years (SD = 191; 95% CI: 900–1648. Calculated overall five years survival rate was 45%.Conclusions. Planned and registered surgical treatment of patients with colon cancer, surgical specialization in colon surgery and adjuvant oncological treatment have shown the same incentive results, reflected in increased survival rate.

To evaluate the technical feasibility and clinical efficacy of percutaneous transhepatic cholecystolithotomy under fluoroscopic guidance in high-risk surgical patients with acute cholecystitis. Sixty-three consecutive patients of high surgical risk with acute calculous cholecystitis underwent percutaneous transhepatic gallstone removal under conscious sedation. The stones were extracted through the 12-Fr sheath using a Wittich nitinol stone basket under fluoroscopic guidance on three days after performing a percutaneous cholecystostomy. Large or hard stones were fragmented using either the snare guide wire technique or the metallic cannula technique. Gallstones were successfully removed from 59 of the 63 patients (94%). Reasons for stone removal failure included the inability to grasp a large stone in two patients, and the loss of tract during the procedure in two patients with a contracted gallbladder. The mean hospitalization duration was 7.3 days for acute cholecystitis patients and 9.4 days for gallbladder empyema patients. Bile peritonitis requiring percutaneous drainage developed in two patients. No symptomatic recurrence occurred during follow-up (mean, 608.3 days). Fluoroscopy-guided percutaneous gallstone removal using a 12-Fr sheath is technically feasible and clinically effective in high-risk surgical patients with acute cholecystitis

The purpose of this study was to assess the efficiency of performing pulmonary procedures in the endoscopy unit in a large teaching hospital. A prospective study from May 20 to July 19, 2013, was designed. The main outcome measures were procedure delays and their reasons, duration of procedural steps starting from patient's arrival to endoscopy unit, turnaround time, total case durations, and procedure wait time. A total of 65 procedures were observed. The most common procedure was BAL (61%) followed by TBLB (31%). Overall procedures for 35 (53.8%) of 65 patients were delayed by ≥ 30 minutes, 21/35 (60%) because of "spillover" of the gastrointestinal and surgical cases into the time block of pulmonary procedure. Time elapsed between end of pulmonary procedure and start of the next procedure was ≥ 30 minutes in 8/51 (16%) of cases. In 18/51 (35%) patients there was no next case in the room after completion of the pulmonary procedure. The average idle time of the room after the end of pulmonary procedure and start of next case or end of shift at 5:00 PM if no next case was 58 ± 53 minutes. In 17/51 (33%) patients the room's idle time was >60 minutes. A total of 52.3% of patients had the wait time >2 days and 11% had it ≥ 6 days, reason in 15/21 (71%) being unavailability of the slot. Most pulmonary procedures were delayed due to spillover of the gastrointestinal and surgical cases into the block time allocated to pulmonary procedures. The most common reason for difficulty encountered in scheduling the pulmonary procedure was slot unavailability. This caused increased procedure waiting time. The strategies to reduce procedure delays and turnaround times, along with improved scheduling methods, may have a favorable impact on the volume of procedures performed in the unit thereby optimizing the existing resources.

Full Text Available Patients with valvular heart disease suffer from atrial fibrillation for more than 12 months after valve surgery and have a low probability of remaining in sinus rhythm. We performed an intra-operative procedure similar to surgical maze ІІІ procedure for conversion of this arrhythmia to sinus rhythm. We did this study to evaluate the efficacy of this procedure to restore the sinus rhythm in patients with valvular heart disease. 28 patients with valvular heart disease and chronic persistent atrial fibrillation underwent different combinations of valve surgery and concomitant reduction of left and right atrial size and resection of both atrial auricles in Shahid Madani cardiothoracic center from September 2004 to October 2008. The procedure for atrial fibrillation treatment was performed with cardiopulmonary bypass and after mitral valve replacement. There was one in-hospital death postoperatively because of respiratory failure, but no other complication till 6 months after the operation. Out of 28 patients, 23 were in sinus rhythm one week after the operation, one patient had junctional rhythm after the operation that restored to sinus rhythm and 4 patients had persistent atrial fibrillation. During the 12-month follow up, atrial fibrillation was corrected in 82.14%. Doppler echocardiography in these patients with sinus rhythm demonstrated good atrial contractility. This procedure on both atria is effective and less invasive than the original maze procedure to eliminate the atrial fibrillation, and can be performed in patients with valvular heart disease without increasing the risk of operation.

Small renal masses (T1a) are commonly diagnosed incidentally and can be treated with nephron-sparing surgery, preserving renal function and obtaining the same oncological results as radical surgery. Bigger lesions (T1b) may be treated in particular situations with a conservative approach too. We present our surgical technique based on robotic assistance for nephron-sparing surgery. We retrospectively analysed our series of 32 consecutive patients (two with 2 tumours and one with 4 bilateral tumours), for a total of 37 robotic nephron-sparing surgery (RNSS) performed between June 2008 and July 2012 by a single surgeon (G.C.). The technique differs depending on tumour site and size. The mean tumour size was 3.6 cm; according to the R.E.N.A.L. Nephrometry Score 9 procedures were considered of low, 14 of moderate and 9 of hight complexity with no conversion in open surgery. Vascular clamping was performed in 22 cases with a mean warm ischemia time of 21.5 min and the mean total procedure time was 149.2 min. Mean estimated blood loss was 187.1 ml. Mean hospital stay was 4.4 days. Histopathological evaluation confirmed 19 cases of clear cell carcinoma (all the multiple tumours were of this nature), 3 chromophobe tumours, 1 collecting duct carcinoma, 5 oncocytomas, 1 leiomyoma, 1 cavernous haemangioma and 2 benign cysts. Associated surgical procedures were performed in 10 cases (4 cholecystectomies, 3 important lyses of peritoneal adhesions, 1 adnexectomy, 1 right hemicolectomy, 1 hepatic resection). The mean follow-up time was 28.1 months ± 12.3 (range 6-54). Intraoperative complications were 3 cases of important bleeding not requiring conversion to open or transfusions. Regarding post-operative complications, there were a bowel occlusion, 1 pleural effusion, 2 pararenal hematoma, 3 asymptomatic DVT (deep vein thrombosis) and 1 transient increase in creatinine level. There was no evidence of tumour recurrence in the follow-up. RNSS is a safe and feasible technique

Povidone-iodine solution is an antiseptic that is used worldwide as surgical paint and is considered to have a low irritant potential. Post-surgical severe irritant dermatitis has been described after the misuse of this antiseptic in the surgical setting. Between January 2011 and June 2013, 27 consecutive patients with post-surgical contact dermatitis localized outside of the surgical incision area were evaluated. Thirteen patients were also available for patch testing. All patients developed dermatitis the day after the surgical procedure. Povidone-iodine solution was the only liquid in contact with the skin of our patients. Most typical lesions were distributed in a double lumbar parallel pattern, but they were also found in a random pattern or in areas where a protective pad or an occlusive medical device was glued to the skin. The patch test results with povidone-iodine were negative. Povidone-iodine-induced post-surgical dermatitis may be a severe complication after prolonged surgical procedures. As stated in the literature and based on the observation that povidone-iodine-induced contact irritant dermatitis occurred in areas of pooling or occlusion, we speculate that povidone-iodine together with occlusion were the causes of the dermatitis epidemic that occurred in our surgical setting. Povidone-iodine dermatitis is a problem that is easily preventable through the implementation of minimal routine changes to adequately dry the solution in contact with the skin. © 2015 The International Society of Dermatology.

Virtual reality in surgical education.

1995-03-01

Virtual reality (VR) is an emerging technology that can teach surgeons new procedures and can determine their level of competence before they operate on patients. Also VR allows the trainee to return to the same procedure or task several times later as a refresher course. Laparoscopic surgery is a new operative technique which requires the surgeon to observe the operation on a video-monitor and requires the acquisition of new skills. VR simulation could duplicate the operative field and thereby enhance training and reduce the need for expensive animal training models. Our preliminary experience has shown that we have the technology to model tissues and laparoscopic instruments and to develop in real time a VR learning environment for surgeons. Another basic need is to measure competence. Surgical training is an apprenticeship requiring close supervision and 5-7 years of training. Technical competence is judged by the mentor and has always been subjective. If VR surgical simulators are to play an important role in the future, quantitative measurement of competence would have to be part of the system. Because surgical competence is "vague" and is characterized by such terms as "too long, too short" or "too close, too far," it is possible that the principles of fuzzy logic could be used to measure competence in a VR surgical simulator. Because a surgical procedure consists of a series of tasks and each task is a series of steps, we will plan to create two important tasks in a VR simulator and validate their use. These tasks consist of laparoscopic knot tying and laparoscopic suturing. Our hypothesis is that VR in combination with fuzzy logic can educate surgeons and determine when they are competent to perform these procedures on patients.

Supportive psychotherapy, in individual or group settings, may help improve surgical outcomes for women and girls living with female genital mutilation (FGM). To assess whether supportive psychotherapy given alongside surgical procedures to correct complications of FGM improves clinical outcomes. We searched major databases including CENTRAL, Medline, African Index Medicus, SCOPUS, PsycINFO, and others. There were no language restrictions. We checked the reference lists of retrieved studies for additional reports of relevant studies. We included studies of girls and women living with any type of FGM who received supportive psychotherapy or client education sessions alongside any surgical procedure to correct health complications from FGM. Two team members independently screened studies for eligibility. There were no eligible studies identified. There is no direct evidence for the benefits or harms of supportive psychotherapy alongside surgical procedures for women and girls living with FGM. Research evidence is urgently needed to guide clinical practice. 42015024639. © 2017 International Federation of Gynecology and Obstetrics.

Achalasia is a primary esophageal motor disorder. The most common symptoms are: dysphagia, chest pain, reflux and weight loss. The esophageal manometry is the standard for diagnosis. The aim of this paper is to determine the effectiveness of the surgical management in patients with achalasia in a tertiary care hospital. A case series consisting of achalasia patients, treated surgically between January and December of 2011. Clinical charts were reviewed to obtain data and registries of the type of surgical procedure, morbidity and mortality. Fourteen patients were identified, with an average age of 49.1 years. The most common symptoms were: dysphagia, vomiting, weight loss and pyrosis. Eight open approaches were performed and six by laparoscopy, with an average length of cardiomyotomy of 9.4 cm. Eleven patients received an antireflux procedure. The effectiveness of procedures performed was 85.7 %. Surgical management offered at this tertiary care hospital does not differ from that reported in other case series, giving effectiveness and safety for patients with achalasia.

To evaluate the literature describing topical use of tranexamic acid or aminocaproic acid for prevention of postoperative bleeding after major surgical procedures. Literature was retrieved through MEDLINE (1946-September 2011) and International Pharmaceutical Abstracts (1970-September 2011) using the terms tranexamic acid, aminocaproic acid, antifibrinolytic, topical, and surgical. In addition, reference citations from publications identified were reviewed. All identified articles in English were evaluated. Clinical trials, case reports, and meta-analyses describing topical use of tranexamic acid or aminocaproic acid to prevent postoperative bleeding were included. A total of 16 publications in the setting of major surgical procedures were included; the majority of data were for tranexamic acid. For cardiac surgery, 4 trials used solutions containing tranexamic acid (1-2.5 g in 100-250 mL of 0.9% NaCl), and 1 trial assessed a solution containing aminocaproic acid (24 g in 250 mL of 0.9% NaCl). These solutions were poured into the chest cavity before sternotomy closure. For orthopedic procedures, all of the data were for topical irrigation solutions containing tranexamic acid (500 mg-3 g in 50-100 mL of 0.9% NaCl) or for intraarticular injections of tranexamic acid (250 mg to 2 g in 20-50 mL of 0.9% sodium chloride, with or without carbazochrome sodium sulfate). Overall, use of topical tranexamic acid or aminocaproic acid reduced postoperative blood loss; however, few studies reported a significant reduction in the number of packed red blood cell transfusions or units given, intensive care unit stay, or length of hospitalization. Topical application of tranexamic acid and aminocaproic acid to decrease postsurgical bleeding after major surgical procedures is a promising strategy. Further data are needed regarding the safety of this hemostatic approach.

Orthognathic surgery procedures mark the endpoint of lengthy orthodontic-surgical preparations and herald the completion of treatment for patients and their families. The main types of procedure are full maxillary Le Fort I osteotomies, mandibular osteotomies and chin surgery. To ensure a successful outcome, all require a favorable environment and extreme technical skill. But, like all surgical operations, they are also subject to peri- and post-operative complications resulting from treatment hazards or errors. Whatever the cause, surgical complications can entail failures in the management of the malformation. By seeking to understand and analyzing these complications, we can already help to prevent and reduce the contingent risks of failure. © EDP Sciences, SFODF, 2016.

Acute surgical care services in rural Sub-Saharan Africa suffer from human resource and systemic constraints. Developing emergency care systems and task sharing aspects of acute surgical care addresses many of these issues. This paper investigates the degree to which specialized non-physicians practicing in a dedicated Emergency Department contribute to the effective and efficient management of acute surgical patients. This is a retrospective review of an electronic quality assurance database of patients presenting to an Emergency Department in rural Uganda staffed by non-physician clinicians trained in emergency care. Relevant de-identified clinical data on patients admitted directly to the operating theater from 2011 to 2014 were analyzed in Microsoft Excel. Overall, 112 Emergency Department patients were included in the analysis and 96% received some form of laboratory testing, imaging, medication, or procedure in the ED, prior to surgery. 72% of surgical patients referred by ED received preoperative antibiotics, and preoperative fluid resuscitation was initiated in 65%. Disposition to operating theater was accomplished within 3 h of presentation for 73% of patients. 79% were successfully followed up to assess outcomes at 72 h. 92% of those with successful follow-up reported improvement in their clinical condition. The confirmed mortality rate was 5%. Specialized non-physician clinicians practicing in a dedicated Emergency Department can perform resuscitation, bedside imaging and laboratory studies to aid in diagnosis of acute surgical patients and arrange transfer to an operating theater in an efficient fashion. This model has the potential to sustainably address structural and human resources problems inherent to Sub-Saharan Africa's current acute surgical care model and will benefit from further study and expansion.

Transanal hemorrhoidal dearterialization (THD) is an effective treatment for hemorrhoidal disease. The ligation of hemorrhoidal arteries (called “dearterialization”) can provide a significant reduction of the arterial overflow to the hemorrhoidal piles. Plication of the redundant rectal mucosa/submucosa (called “mucopexy”) can provide a repositioning of prolapsing tissue to the anatomical site. In this paper, the surgical technique and perioperative patient management are illustrated. Followi...

Surgical Management of Chronic Pancreatitis.

Advances over the past decade have indicated that a complex interplay between environmental factors, genetic predisposition, alcohol abuse, and smoking lead towards the development of chronic pancreatitis. Chronic pancreatitis is a complex disorder that causes significant and chronic incapacity in patients and a substantial burden on the society. Major advances have been made in the etiology and pathogenesis of this disease and the role of genetic predisposition is increasingly coming to the fore. Advances in noninvasive diagnostic modalities now allow for better diagnosis of chronic pancreatitis at an early stage of the disease. The impact of these advances on surgical treatment is beginning to emerge, for example, patients with certain genetic predispositions may be better treated with total pancreatectomy versus lesser procedures. Considerable controversy remains with respect to the surgical management of chronic pancreatitis. Modern understanding of the neurobiology of pain in chronic pancreatitis suggests that a window of opportunity exists for effective treatment of the intractable pain after which central sensitization can lead to an irreversible pain syndrome in patients with chronic pancreatitis. Effective surgical procedures exist for chronic pancreatitis; however, the timing of surgery is unclear. For optimal treatment of patients with chronic pancreatitis, close collaboration between a multidisciplinary team including gastroenterologists, surgeons, and pain management physicians is needed.

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

A COMPARATIVE STUDY OF 2 AGENTS, AIR AND DISTILLED WATER FOR INFLATION OF THE CUFFS OF ENDOTRACHEAL TUBES DURING LAPAROSCOPIC SURGICAL PROCEDURES UNDER GENERAL ANAESTHESIA

Full Text Available BACKGROUND & AIM During Nitrous Oxide+ Oxygen anaesthesia and during laparoscopic surgeries using carbon dioxide for creating pneumoperitoneum, if cuff of endotracheal tube is inflated with air, cuff pressure can rise to dangerous limits and it can produce ischemia of tracheal mucosa. Hence distilled water as an alternative agent to air for inflation of cuffs of endotracheal tubes was used for our study. Our aim is to investigate the difference in increase of intra-cuff pressure with time during laparoscopic surgical procedures under general endotracheal anaesthesia with Nitrous oxide+ Oxygen+ relaxant technique when cuffs of endotracheal tube were inflated by air & distilled water. METHODS Fifty patients (n=50 undergoing different laparoscopic surgical procedures under general endotracheal anaesthesia were randomly divided into 2 groups. In group A, air was used & in group D, distilled water was used to inflate the cuffs of endotracheal tubes. General anaesthesia was given with Nitrous oxide+ Oxygen+ relaxant technique. The intra-cuff pressures of endotracheal tube cuffs were recorded in the beginning and at the end of laparoscopic surgical procedures. Increase of pressures with time were recorded and analysed. RESULTS In group in whom we inflated the cuffs with air, there was a significant increase in intra-cuff pressures with time and there was definite diffusion of gases into the cuffs. Increase of pressure with time was statistically highly significant (P=0.00001. But in group in whom we used distilled water to inflate the cuffs, there was no change in the volume of water used for inflation and water came out of cuffs at the end of the laparoscopic surgical procedures. No additional air could be aspirated from the cuffs at the end of laparoscopic surgeries in distilled water group, indicating that there was no diffusion of gases into the cuffs or the gases diffused got dissolved in distilled water. Hence there was no increase of volume

A multicenter study of changes in Scoliosis Research Society (SRS) outcome measures after surgical treatment of adolescent idiopathic scoliosis (AIS). To evaluate changes in patient determined outcome measures between 2 and 5 years after AIS surgery. Current surgical procedures have been shown to improve subjective measures in patients with AIS. At 2-year follow-up, AIS patients reported significant improvement in all 4 preoperative domains of the SRS questionnaire. In addition, the major Cobb angle was shown to be negatively correlated with preoperative scores in the pain, general self-image, and general function domains. Five-year SRS scores have not been evaluated previously. A multicenter, prospectively generated database was used to obtain perioperative, radiographic, and SRS-24 outcomes data. The inclusion criteria were: a diagnosis of AIS, surgical treatment (anterior, posterior, or combined), a comprehensive set of radiographic measures, and completed preoperative, 2-year, and 5-year SRS questionnaires. Repeated measures analysis of variance was used to compare changes in patient responses for each of the 7 outcome domains. Univariate analysis of variance was used to compare the change in pain score at 5 years to the level of the lowest instrumented vertebrae and surgical approach. A correlation analysis was used to determine the association between changes in any of the radiographic variables and changes in SRS scores. The data were checked for normality and equal variances, and the level of significance was set at P < 0.01. Forty-nine patients (42 women, 7 men; 14.2 +/- 2.1 year old; 5.4 +/- 0.6 years follow-up) met the inclusion criteria for this study. Thirty-seven of 49 (76%) of these patients underwent an open or thoracoscopic anterior procedure. SRS-24 scores improved significantly in 3 of the 4 preoperative domains at the 2-year visit. At 5 years postop, a statistically significant decrease in the pain score (4.2 +/- 0.6 to 3.9 +/- 0.9, P = 0

Minimally invasive surgical procedures for the treatment of lumbar disc herniation

as an intermediate therapeutical option between conservative and operative management of small lumbar disc herniations or protrusions causing sciatica. Two RCT comparing transforaminal endoscopic procedures with microdiscectomy in patients with sciatica and small non-sequestered disc herniations show comparable short and medium term overall success rates. Concerning speed of recovery and return to work a trend towards more favourable results for the endoscopic procedures is noted. It is doubtful though, whether these results from the eleven and five years old studies are still valid for the more advanced procedures used today. The only RCT comparing the results of automated percutaneous lumbar discectomy to those of microdiscectomy showed clearly superior results of microdiscectomy. Furthermore, success rates of automated percutaneous lumbar discectomy reported in the RCT (29% differ extremely from success rates reported in case series (between 56% and 92%. The literature search retrieves no controlled trials to assess efficacy and/or effectiveness of laser-discectomy, percutaneous manual discectomy or endoscopic procedures using a posterior approach in comparison to the standard procedures. Results from recent case series permit no assessment of efficacy, especially not in comparison to standard procedures. Due to highly selected patients, modi-fications of operative procedures, highly specialised surgical units and poorly standardised outcome assessment results of case series are highly variable, their generalisability is low. The results of the five economical analyses are, due to conceptual and methodological problems, of no value for decision-making in the context of the German health care system. Discussion: Aside from low methodological study quality three conceptual problems complicate the interpretation of results. 1. Continuous further development of technologies leads to a diversity of procedures in use which prohibits generalisation of study results

The accuracy of echocardiography versus surgical and pathological classification of patients with ruptured mitral chordae tendineae: a large study in a Chinese cardiovascular center

Science.gov (United States)

2011-01-01

Background The accuracy of echocardiography versus surgical and pathological classification of patients with ruptured mitral chordae tendineae (RMCT) has not yet been investigated with a large study. Methods Clinical, hemodynamic, surgical, and pathological findings were reviewed for 242 patients with a preoperative diagnosis of RMCT that required mitral valvular surgery. Subjects were consecutive in-patients at Fuwai Hospital in 2002-2008. Patients were evaluated by thoracic echocardiography (TTE) and transesophageal echocardiography (TEE). RMCT cases were classified by location as anterior or posterior, and classified by degree as partial or complete RMCT, according to surgical findings. RMCT cases were also classified by pathology into four groups: myxomatous degeneration, chronic rheumatic valvulitis (CRV), infective endocarditis and others. Results Echocardiography showed that most patients had a flail mitral valve, moderate to severe mitral regurgitation, a dilated heart chamber, mild to moderate pulmonary artery hypertension and good heart function. The diagnostic accuracy for RMCT was 96.7% for TTE and 100% for TEE compared with surgical findings. Preliminary experiments demonstrated that the sensitivity and specificity of diagnosing anterior, posterior and partial RMCT were high, but the sensitivity of diagnosing complete RMCT was low. Surgical procedures for RMCT depended on the location of ruptured chordae tendineae, with no relationship between surgical procedure and complete or partial RMCT. The echocardiographic characteristics of RMCT included valvular thickening, extended subvalvular chordae, echo enhancement, abnormal echo or vegetation, combined with aortic valve damage in the four groups classified by pathology. The incidence of extended subvalvular chordae in the myxomatous group was higher than that in the other groups, and valve thickening in combination with AV damage in the CRV group was higher than that in the other groups.

Long-term patency is required during treatment for benign airway stenosis. This study investigated the effectiveness of surgical airway plasty for benign airway stenosis. Clinical courses of 20 patients, who were treated with surgical plasty for their benign airway stenosis, were retrospectively investigated. Causes of stenosis were tracheobronchial tuberculosis in 12 patients, post-intubation stenosis in five patients, malacia in two patients, and others in one patient. 28 interventional pulmonology procedures and 20 surgical plasty were performed. Five patients with post-intubation stenosis and four patients with tuberculous stenosis were treated with tracheoplasty. Eight patients with tuberculous stenosis were treated with bronchoplasty, and two patients with malacia were treated with stabilization of the membranous portion. Anastomotic stenosis was observed in four patients, and one to four additional treatments were required. Performance status, Hugh-Jones classification, and ventilatory functions were improved after surgical plasty. Outcomes were fair in patients with tuberculous stenosis and malacia. However, efficacy of surgical plasty for post-intubation stenosis was not observed. Surgical airway plasty may be an acceptable treatment for tuberculous stenosis. Patients with malacia recover well after surgical plasty. There may be untreated patients with malacia who have the potential to benefit from surgical plasty.

The purpose of this study was to present a new procedure to treat symptomatic conjunctivochalasis (CCh) and to evaluate its efficacy. Forty-two patients with symptomatic CCh refractory to medical management were included on this study. Twenty-two patients (n  =  32, eyes; n  =  14 women and n  =  8 men) underwent the new electrocoagulation procedure (Group I). Twenty patients (n  =  27 eyes; n  =  11 women and n  =  9 men) underwent crescent-shaped conjunctiva resection (Group II). Ocular Surface Disease Index (OSDI) was used to evaluate ocular symptoms. There was a significant difference in mean and SD operation time between Group I (8.67 ± 2.07 minutes) and Group II (20.45 ± 3.98 minutes; P Electrocoagulation of the conjunctiva can successfully treat symptomatic CCh with earlier symptomatic attenuation and less operation time than traditional conjunctiva resection.

The use of blood products in 1480 consecutive cases of adult cardiac surgical procedures over a period of 15 mth was studied retrospectively using the database of the Department of Anaesthesia of the Institut de Cardiologie de Montréal. Use of blood products was compared in patients having (1) coronary artery bypass grafting, (2) valvular surgery, (3) or a combination of 1 and 2. First operations were compared with reoperations. Overall, the use of homologous blood products was greatest in patients of Group 3, intermediate in patients of Group 2, and smallest in patients of Group 1. Reoperations were associated with an increase in intraoperative transfusion of packed red blood cells, but postoperative chest drainage was similar to first operations. When all blood products (packed red blood cells, fresh frozen plasma and platelets) were taken into consideration, patients undergoing primary CABG or valve surgery were the least exposed to homologous blood donors (five and six units transfused respectively). Repeat CABG was associated with an intermediate exposure to homologous blood products (eight units). Finally, primary and repeat combined procedures, and repeat valve surgery were associated with the greatest exposure to foreign blood products (10, 13 and 10 units respectively). The data presented in this study provide a rational basis for stratification of procedures according to the expected use of blood products, particularly in view of future studies which may be planned to examine the efficiency of blood conservation strategies.

To elucidate the association between medical procedures and sporadic Creutzfeldt-Jakob disease (sCJD), we analyzed medical procedures (any surgical procedure, neurosurgery, ophthalmic surgery, and blood transfusion) for patients registered by the CJD Surveillance Committee in Japan during 1999–2008. We conducted an age-stratified case–control study with 753 sCJD patients and 210 controls and a study of patients who underwent neurosurgical or ophthalmic surgical procedures at the same hospital. Although the control group was relatively small, no evidence was found that prion disease was transmitted through the investigated medical procedures before onset of sCJD. After onset of sCJD, 4.5% of the sCJD patients underwent operations, including neurosurgical for 0.8% and ophthalmic for 1.9%; no special precautions against transmission of prion diseases were taken. Fortunately, we have not identified patients with prion disease attributed to these operations. Our findings indicate that surgical procedures or blood transfusion had little effect on the incidence of sCJD. PMID:19193271

Angioplasty with stent implant is a less invasive procedure than surgical intervention in the treatment of significant stenosis of the common cervical carotid artery (common and internal) (5). Currently the major published studies, in which angioplasty and surgical treatment are compared, show similar results in the major events, as cerebrovascular accidents and mortality, but a greater significant difference in the apparition of acute myocardial infarction, during surgical intervention (5,11). The objective of this study is to compare in both treatment methods the major and minor clinical events, like cerebrovascular accident, acute myocardial infarction, death, bradycardia, hypotension and encephalopathy during the intervention, the hospitalization and the follow-up year, as well as the re-intervention, the time of hospital stay and the complications of the surgical incision. Materials and methods: in this study of historical cohort, 46 patients with significant stenosis of the cervical carotid arteries, who were subjected to intervention from January 1st 2001 to December 31st 2003, were included. 21 patients were treated with angioplasty and stent implant and 25 with surgery (endarterectomy) Results: 1 (4.8%) major cerebrovascular accident occurred during angioplasty, whereas none occurred in the patients treated with surgery. 1 (4%) acute myocardial infarction occurred during intervention in the group of patients treated with surgery, and none in the patients treated with angioplasty. No deaths occurred in any of the groups during intervention, hospitalization and the follow-up year. After 8 months 1 (4%) patient treated with surgery was intervened again with angioplasty and stent implant. There were no statistically significant differences between both groups during hospitalization, and in the apparition of minor complications as bradycardia and hypotension. 2 (8%) complications related to the incision of the neck compromising cranial nerves, occurred in the

Full Text Available Introduction: Parathyroidectomy (PTx is the selecte treatment for patients with severe secondary hyperparathyroidism, refractory to medical treatment. There is not enough information about this procedure in Argentina, that is the reason why we performed this study. Methods: 255 patients with PTx were included from the year 2003 to 2007 on a voluntary register. Studies of pre-surgical localization, phosphocalcic metabolism laboratories before and after surgery were evaluated, and the type of surgical technique used. The persistence and recurrence of post-surgical hyperparathyroidism was analyzed. Results: The PTx rate was 2,7/1000 patients year. 83% of the patients had neck echography and 59% Sestamibi scans with Tc 99. There was a positive correlation (p<0,001 between the number of detected glands by echography and Sestamibi. The parathyroidectomy performed was: subtotal in 77%, total with self-implant in 14% and total without self-implant in 9%. There were significant falls of Ca and P, Alkaline Phosphatase and PTH (1744±788 pg/ml to 247±450 pg/ml; p<0.0001 post-surgical. 2.4 ±2,5 months after the PTx, 72% of patients had PTH <2 50 pg/ml, 19,8% had persistence and 8,3% had recurrence. According to the type of surgery, the persistence and recurrence were for subtotal PTx 22% and 8,3%, total PTx with implant 11% and 11%, and total PTx without selfimplant 13% and 4% respectively. The performance of the Sestamibi scan did not affect the PTx results. No noticeable differences were observed among the centers for persistence and recurrence. Conclusions: The PTx rate was very low, echography was the preferred method of pre-surgical localization, and subtotal PTx was the most used surgical technique. PTx was successful in most of the patients, and persistence and recurrence were not related to the technique.

Cognitive Outcomes of Cardiovascular Surgical Procedures in the Old: An Important but Neglected Area.

2016-12-01

Older individuals can now undergo invasive cardiovascular procedures without serious concern about mortality, and the numbers and proportions of the over 65s and 85s doing so in Australia has been increasing over the last 20 years. There is overwhelming evidence linking cardiovascular conditions to late-life (65 years and over) cognitive impairment and dementia including Alzheimer's Disease, primarily due to impaired cerebrovascularisation and cascading neuropathological processes. Somewhat paradoxically, these cardiovascular interventions, carried out with the primary aim of revascularisation, are not usually associated with short- or long-term improvements in cognitive function in older adults. We discuss factors associated with cognitive outcomes post-cardiovascular surgeries in patients over 65 years of age. There are many opportunities for future research: we know almost nothing about cognitive outcomes following invasive cardiac procedures in the oldest old (85 years and over) nor how to predict the cognitive/delirium outcome using pre-surgical data, and lastly, intervention opportunities exist both pre and postoperatively that have not been tested. As our population ages with increased cardiovascular burden and rates of cardiovascular interventions and surgeries, it is critical that we understand the cognitive consequences of these procedures, who is at greatest risk, and ways to optimise cognition.

1995-01-01

Purpose: To assess the impact of high-dose three-dimensional conformal radiotherapy (3DCRT) on potency in patients treated for clinically localized prostate cancer and to identify factors that might predict the outcome of sexual function following treatment. Methods and Materials: One hundred twenty-four consecutive patients treated with 3DCRT for localized prostate cancer at UCSF between 1991-1993 were included in this retrospective analysis. Patient responses were obtained from a mailed questionnaire, telephone interviews, or departmental records. Median follow-up was 21 months. Results: Sixty patients reported having sexual function prior to 3DCRT, including 47 who were fully potent and 13 who were marginally potent. Of the remaining 64 patients, 45 were impotent, 7 were on hormones, 1 was status-postorchiectomy, and 11 were not evaluable. Following 3DCRT, 37 of 60 patients (62%) retained sexual function sufficient for intercourse. Of those with sexual function before irradiation, 33 of 47 (70%) of patients fully potent and 4 of 13 (31%) of patients marginally potent maintained function sufficient for intercourse (p < 0.01). Potency was retained in 6 of 15 (40%) patients with a history of a major urologic surgical procedure (MUSP) and in 31 of 45 (69%) with no history of a MUSP (p < 0.04). Transurethral resection of the prostate was the MUSP in eight of these patients, with four (50%) maintaining sexual function. Conclusions: Patients who receive definitive 3DCRT for localized prostate cancer appear to maintain potency similar to patients treated with conventional radiotherapy. However, patients who are marginally potent at presentation or who have a history of a MUSP appear to be at increased risk of impotence following 3DCRT

Surgical congenital malformations often represent years of treatment, large number of hospital stays, treatment procedures, and long-term functional sequels affecting patients' psychosocial functioning. Both functional defects and psychosocial difficulties that occur commonly in childhood may pass through adolescence on to adulthood. This overview presents reports published over the past 3 decades to elucidate the long-term psychosocial consequences of surgical congenital malformations. Literature searches conducted on PubMed database revealed that less than 1% of all the records of surgical congenital malformations described long-term psychosocial consequences, but with diverse findings. This inconsistency may be due to methodological differences or deficiencies; especially in study design, patient sampling, and methods. Most of the studies revealed that the functional deficits may have great impact on patients' mental health, psychosocial functioning, and QoL; both short- and long-term negative consequences. Factors other than functional problems, e.g., repeated anesthesia, multiple hospitalization, traumatic treatment procedures, and parental dysfunctioning, may also predict long-term mental health and psychosocial functioning. Through multidisciplinary approach, pediatric surgeons should also be aware of deficits in emotional and psychosocial functioning. To achieve overall optimal psychosocial functioning, the challenge is to find a compromise between physically optimal treatment procedures and procedures that are not psychologically detrimental.

To investigate the feasibility and safety of da Vinci robotic surgical system in rectal cancer radical operation, and to summarize its short-term efficacy and clinical experience. Data of 101 cases undergoing da Vinci robotic surgical system for rectal cancer radical operation from March 2010 to September 2012 were retrospectively analyzed. Evaluation was focused on operative procedure, complication, recovery and pathology. All the 101 cases underwent operation successfully and safely without conversion to open procedure. Rectal cancer radical operation with da Vinci robotic surgical system included 73 low anterior resections and 28 abdominoperineal resections. The average operative time was (210.3±47.2) min. The average blood lose was (60.5±28.7) ml without transfusion. Lymphadenectomy harvest was 17.3±5.4. Passage of first flatus was (2.7±0.7) d. Distal margin was (5.3±2.3) cm without residual cancer cells. The complication rate was 6.9%, including anastomotic leakage(n=2), perineum incision infection(n=2), pulmonary infection (n=2), urinary retention (n=1). There was no postoperative death. The mean follow-up time was(12.9±8.0) months. No local recurrence was found except 2 cases with distant metastasis. Application of da Vinci robotic surgical system in rectal cancer radical operation is safe and patients recover quickly The short-term efficacy is satisfactory.

The purposes of this study were to combine a thorough understanding of the technical aspects of the Whipple procedure with advanced rendering techniques by introducing a virtual Whipple procedure and to evaluate the utility of this new rendering technique in prediction of the arterial variants that cross the anticipated surgical resection plane. The virtual Whipple is a novel technique that follows the complex surgical steps in a Whipple procedure. Three-dimensional reconstructed angiographic images are used to identify arterial variants for the surgeon as part of the preoperative radiologic assessment of pancreatic and ampullary tumors.

To evaluate the evolution of surgical management in a large population of patients with Marfan syndrome. This is a retrospective study of patients fulfilling the Ghent criteria for Marfan syndrome, who visited the Centre de référence national pour le syndrome de Marfan et apparentés and underwent a surgical event before or during follow-up in the centre. One thousand and ninety-seven patients with Marfan syndrome, according to international criteria, came to the clinic between 1996 and 2010. Aortic surgery was performed in 249 patients (22.7%; 20 children and 229 adults), including the Bentall procedure in 140 patients (56%) and valve-sparing surgery in 88 patients (35%); a supracoronary graft was performed in 19 patients (7.6%), usually for aortic dissection. During the past 20 years, the predominant reason for aortic surgery has switched from aortic dissection to aortic dilatation, while age at surgery has tended to increase (from 32.4 ± 11.9 years to 35.2 ± 12.4 years; P=0.075). Mitral valve surgery was performed in 61 patients (5.6%; six children and 55 adults), including 37 valvuloplasties (60.6%) and 18 mitral valve replacements (29.5%). No significant difference was observed when comparing mitral valve surgery before and after 2000. Surgery performed in patients with Marfan syndrome has switched from emergency surgery for aortic dissection to elective surgery for aortic dilatation; this is associated with surgery performed at an older age despite the indication for surgery having decreased from 60mm to 50mm. No significant evolution was observed for mitral valve surgery. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Full Text Available Abstract Background The hierarchical nature of medical education has been thought necessary for the safe care of patients. In this setting, medical students in particular have limited opportunities for experiential learning. We report on a student-faculty collaboration that has successfully operated an annual, short-term surgical intervention in Haiti for the last three years. Medical students were responsible for logistics and were overseen by faculty members for patient care. Substantial planning with local partners ensured that trip activities supplemented existing surgical services. A case review was performed hypothesizing that such trips could provide effective surgical care while also providing a suitable educational experience. Findings Over three week-long trips, 64 cases were performed without any reported complications, and no immediate perioperative morbidity or mortality. A plurality of cases were complex urological procedures that required surgical skills that were locally unavailable (43%. Surgical productivity was twice that of comparable peer institutions in the region. Student roles in patient care were greatly expanded in comparison to those at U.S. academic medical centers and appropriate supervision was maintained. Discussion This demonstration project suggests that a properly designed surgical trip model can effectively balance the surgical needs of the community with an opportunity to expose young trainees to a clinical and cross-cultural experience rarely provided at this early stage of medical education. Few formalized programs currently exist although the experience above suggests the rewarding potential for broad-based adoption.

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.

Second branchial cleft anomalies predispose to recurrent infections, and surgical resection is recommended as the treatment of choice. There is no clear consensus regarding the timing or surgical technique in the operative treatment of these anomalies. Our aim was to compare the effect of age and operative techniques to patient characteristics and treatment outcome. A retrospective study of pediatric patients treated for second branchial sinuses or fistulae during 1998-2012 at two departments in our academic tertiary care referral center. Comparison of patient characteristics, preoperative investigations, surgical techniques and postoperative sequelae. Our data is based on 68 patients, the largest series in the literature. One-fourth (24%) of patients had any infectious symptoms prior to operative treatment. Patient demographics, preoperative investigations, use of methylene blue, or tonsillectomy had no effect on the surgical outcome. There were no re-operations due to residual disease. Three complications were observed postoperatively. Our patient series of second branchial cleft sinuses/fistulae is the largest so far and enables analyses of patient characteristics and surgical outcomes more reliably than previously. Preoperative symptoms are infrequent and mild. There was no difference in clinical outcome between the observed departments. Performing ipsilateral tonsillectomy gave no outcome benefits. The operation may be delayed to an age of approximately three years when anesthesiological risks are and possible harms are best avoided. Considering postoperative pain and risk of postoperative hemorrhage a routine tonsillectomy should not be included to the operative treatment of second branchial cleft fistulae.

In our hypothesis, the newly developed program SPM (surgical procedure manager) will ensure successful standardization and efficiency of the FESS (functional endoscopic sinus surgery) and therefore make a decisive contribution in terms of economization and improvement of intraoperative quality. Between 27th March 2015 and 8th October 2015, data from 259 FESS procedures were collected using the SPM. The study took place at the surgical desk, an operating room in the ACQUA clinic in Leipzig, Germany. 233 FESS (90%) of the total FESS (n = 259, 100%) were conducted entirely with SPM. 26 SPM terminations (10%) of 259 FESS remain, which are classified as actual SPM terminations-when the surgeon intentionally stops the SPM. The maximum time slot decreased clearly from 1 h 39 min (period A) to 1 h 10 min (period B). A time reduction can also be seen with the minimum duration of 13.5 min compared to 11 min. The variability of the time slot also decreases since the standard deviation is reduced by 4.5 min. On the basis of available recordings it can be postulated that the application of SPM is suitable for standardization for FESS. Standardization by means of SPM and minimal development can be recognized over a period of time. The SPM makes it possible to transfer the general advantages of mechanization on a concrete FESS and do not influence the medical processes nor even restrict the medical freedom. The users are still entirely free in the implementation of the respective procedure.

Surgical auditing has been developed in order to benchmark and to facilitate quality improvement. The aim of this review is to determine if auditing combined with systematic feedback of information on process and outcomes of care results in lower costs of surgical care. A systematic search of published literature before 21-08-2013 was conducted in Pubmed, Embase, Web of Science, and Cochrane Library. Articles were selected if they met the inclusion criteria of describing a surgical audit with cost-evaluation. The systematic search resulted in 3608 papers. Six studies were identified as relevant, all showing a positive effect of surgical auditing on quality of healthcare and therefore cost savings was reported. Cost reductions ranging from $16 to $356 per patient were seen in audits evaluating general or vascular procedures. The highest potential cost reduction was described in a colorectal surgical audit (up to $1,986 per patient). All six identified articles in this review describe a reduction in complications and thereby a reduction in costs due to surgical auditing. Surgical auditing may be of greater value when high-risk procedures are evaluated, since prevention of adverse events in these procedures might be of greater clinical and therefore of greater financial impact. This systematic review shows that surgical auditing can function as a quality instrument and therefore as a tool to reduce costs. Since evidence is scarce so far, further studies should be performed to investigate if surgical auditing has positive effects to turn the rising healthcare costs around. In the future, incorporating (actual) cost analyses and patient-related outcome measures would increase the audits' value and provide a complete overview of the value of healthcare.

Postoperative nausea and vomiting (PONV) is a common source of patient discomfort and decreased satisfaction. Aromatherapy has been identified as a complementary modality for the prevention and management of PONV. The purpose of this study was to assess the effect of aromatherapy on the severity of postoperative nausea (PON) in women undergoing surgical procedures in the postanesthesia care unit. Women complaining of PON received traditional antiemetics, inhalation of peppermint oil, or saline vapor. A visual analog scale was used to rate nausea at the first complaint; at 5 minutes after intervention; and, if nausea persisted, at 10 minutes after intervention. At both 5 and 10 minutes, statistical analysis showed no significant differences between intervention and nausea rating. Obtaining eligible subjects was challenging. Although many women consented, most received intraoperative antiemetics and did not report nausea postoperatively. Copyright © 2012 American Society of PeriAnesthesia Nurses.

Full Text Available Aim: aim of the study was to evaluate the efficiency of two different surgical treatments of vesicoureteral reflux (VUR on succesfull rate and patient outcome. Methods: Retrospective study on children with primary VUR and their surgical treatment from 1999 to 2014 in the University Clinic for Pediatric Surgery in Skopje. A total of 76 children (114 ureters with VUR ranging from second to fifth grade were treated surgically, 44 patients (67 ureters with an open surgical technique and 32 patients (47 ureters with endoscopic treatment ”STING” procedure. The following parameters were analyzed: duration of the intervention, duration of the hospitalization, the need for antibiotics and analgesic therapy and the need for blood and blood derivatives transfusion. The result of the surgical treatment was also validated. A good result was considered when reduction of VUR by 2 degrees with the endoscopic method or by 3 degrees in the open surgical technique was noticed. Results: Using open surgical technique, patients were hospitalized for an average of 9 days (range from 5 to 13 days. All children received double antibiotic therapy. The need for analgesics lasted for 3 to 4 days. 90% of treated children needed blood and/or blood derivatives transfusion. Success rate with this method was 93.8%. Endoscopic procedure was performed as a one-day surgical procedure. The average duration was 15 minutes. Single, prophylactic dose of antibiotic was ordinated. There was no need for blood and/or blood derivatives transfusion. The overall success of the treatment was about 70%. Conclusion: Open surgical procedure is used for more complicated cases, VUR grade IV-V or by previously failed. Endoscopic, “STING” procedure was commonly used for patients with VUR grade greater than 2, after previously failed conservative treatment, febrile urinary infection despite antibiotic prophylaxis and/or emergence of new scarring in the renal parenchyma.

A retrospective study of 36 cases of pancreatic cyst treated during the recent 13 years was performed from the aspects of imaging and treatment. Visualization of the internal structure by abdominal echography and CT was rare in inflammatory cysts, but frequent in neoplastic cysts. Differentiation between mucous and serous cystadenoma on the basis of properties was possible. Retrograde pancreatography, which disclosed the entire pancreatic ductal system, was important in determining surgical procedure. Angiography was effective for differentiating between benign and malignant cysts, even though some of the inflammatory cysts suggested malignant findings. The most frequent therapy in cases of inflammatory cyst was internal fistulization, with additional side-to-side pancreaticojejunostomy as a procedure for underlying chronic pancreatitis. Neoplastic cysts were resected in all cases, and the procedure for pancreatic cancer was modified for use in the cases of cystic adenocarcinoma. The remote postoperative results in the cases of inflammatory cyst were satisfactory: symptomatic improvement was found in 83.1 % of patients and occupational rehabilitation in 70.6 %. All of the three patients with cystic adenocarcinoma are well, including the one surviving a maximum period of 4 years and 10 months. (author)
