  1. Surgical approaches to complex vascular lesions: the use of virtual reality and stereoscopic analysis as a tool for resident and student education. (United States)

    Agarwal, Nitin; Schmitt, Paul J; Sukul, Vishad; Prestigiacomo, Charles J


    Virtual reality training for complex tasks has been shown to be of benefit in fields involving highly technical and demanding skill sets. The use of a stereoscopic three-dimensional (3D) virtual reality environment to teach a patient-specific analysis of the microsurgical treatment modalities of a complex basilar aneurysm is presented. Three different surgical approaches were evaluated in a virtual environment and then compared to elucidate the best surgical approach. These approaches were assessed with regard to the line-of-sight, skull base anatomy and visualisation of the relevant anatomy at the level of the basilar artery and surrounding structures. Overall, the stereoscopic 3D virtual reality environment with fusion of multimodality imaging affords an excellent teaching tool for residents and medical students to learn surgical approaches to vascular lesions. Future studies will assess the educational benefits of this modality and develop a series of metrics for student assessments.

    Morales, Mario P; Mancini, Gregory J; Miedema, Brent W; Rangnekar, Nitin J; Koivunen, Debra G; Ramshaw, Bruce J; Eubanks, W Stephen; Stephenson, Hugh E


    New advances in endoscopic surgery make it imperative that future gastrointestinal surgeons obtain adequate endoscopy skills. An evaluation of the 2001-02 general surgery residency endoscopy experience at the University of Missouri revealed that chief residents were graduating with an average of 43 endoscopic cases. This met American Board of Surgery (ABS) and Accreditation Council for Graduate Medical Education (ACGME) requirements but is inadequate preparation for carrying out advanced endoscopic surgery. Our aim was to determine if endoscopy volume could be improved by dedicating specific staff surgeon time to a gastrointestinal diagnostic center at an affiliated Veterans Administration Hospital. During the academic years 2002-05, two general surgeons who routinely perform endoscopy staffed the gastrointestinal endoscopy center at the Harry S. Truman Hospital two days per week. A minimum of one categorical surgical resident participated during these endoscopy training days while on the Veterans Hospital surgical service. A retrospective observational review of ACGME surgery resident case logs from 2001 to 2005 was conducted to document the changes in resident endoscopy experience. The cases were compiled by postgraduate year (PGY). Resident endoscopy case volume increased 850% from 2001 to 2005. Graduating residents completed an average of 161 endoscopies. Endoscopic experience was attained at all levels of training: 26, 21, 34, 23, and 26 mean endoscopies/year for PGY-1 to PGY-5, respectively. Having specific endoscopy training days at a VA Hospital under the guidance of a dedicated staff surgeon is a successful method to improve surgical resident endoscopy case volume. An integrated endoscopy training curriculum results in early skills acquisition, continued proficiency throughout residency, and is an efficient way to obtain endoscopic skills. In addition, the foundation of flexible endoscopic skill and experience has allowed early integration of surgery

  3. Practice management education during surgical residency. (United States)

    Jones, Kory; Lebron, Ricardo A; Mangram, Alicia; Dunn, Ernest


    Surgical education has undergone radical changes in the past decade. The introductions of laparoscopic surgery and endovascular techniques have required program directors to alter surgical training. The 6 competencies are now in place. One issue that still needs to be addressed is the business aspect of surgical practice. Often residents complete their training with minimal or no knowledge on coding of charges or basic aspects on how to set up a practice. We present our program, which has been in place over the past 2 years and is designed to teach the residents practice management. The program begins with a series of 10 lectures given monthly beginning in August. Topics include an introduction to types of practices available, negotiating a contract, managed care, and marketing the practice. Both medical and surgical residents attend these conferences. In addition, the surgical residents meet monthly with the business office to discuss billing and coding issues. These are didactic sessions combined with in-house chart reviews of surgical coding. The third phase of the practice management plan has the coding team along with the program director attend the outpatient clinic to review in real time the evaluation and management coding of clinic visits. Resident evaluations were completed for each of the practice management lectures. The responses were recorded on a Likert scale. The scores ranged from 4.1 to 4.8 (average, 4.3). Highest scores were given to lectures concerning negotiating employee agreements, recruiting contracts, malpractice insurance, and risk management. The medical education department has tracked resident coding compliance over the past 2 years. Surgical coding compliance increased from 36% to 88% over a 12-month period. The program director who participated in the educational process increased his accuracy from 50% to 90% over the same time period. When residents finish their surgical training they need to be ready to enter the world of business

  4. Dexterity testing and residents' surgical performance. (United States)

    Kirby, T J


    1. With some exceptions, those who choose ophthalmology as a career may approximate the general population in innate manual dexterity. 2. Many factors other than manual dexterity influence the development of surgical skills by residents. 3. If dexterity testing is to be used, the addition or inclusion of tests for spatial aptitudes may be more helpful than simple dexterity tests alone. The predictive value of such tests for surgical performance would need vertification. 4. The development of a special test directly related to handling surgical instruments, to cutting, and to sewing (the criteria) may be more practical than the ones used in this study.

  5. Impact of Integrated Vascular Residencies on Academic Productivity within Vascular Surgery Divisions. (United States)

    Kim, Bradford J; Valsangkar, Nakul P; Liang, Tiffany W; Murphy, Michael P; Zimmers, Teresa A; Bell, Teresa M; Davies, Mark G; Koniaris, Leonidas G


    Changing training paradigms in vascular surgery have been introduced to reduce overall training time. Herein, we sought to examine how shortened training for vascular surgeons may have influenced overall divisional academic productivity. Faculty from the top 55 surgery departments were identified according to National Institutes of Health (NIH) funding. Academic metrics of 315 vascular surgery, 1,132 general surgery, and 2,403 other surgical specialties faculty were examined using institutional Web sites, Scopus, and NIH Research Portfolio Online Reporting Tools from September 1, 2014, to January 31, 2015. Individual-level and aggregate numbers of publications, citations, and NIH funding were determined. The mean size of the vascular divisions was 5 faculty. There was no correlation between department size and academic productivity of individual faculty members (R(2) = 0.68, P = 0.2). Overall percentage of vascular surgery faculty with current or former NIH funding was 20%, of which 10.8% had major NIH grants (R01/U01/P01). Vascular surgery faculty associated with integrated vascular training programs demonstrated significantly greater academic productivity. Publications and citations were higher for vascular surgery faculty from institutions with both integrated and traditional training programs (48 of 1,051) compared to those from programs with integrated training alone (37 of 485) or traditional fellowships alone (26 of 439; P productivity was improved within vascular surgery divisions with integrated training programs or both program types. These data suggest that the earlier specialization of integrated residencies in addition to increasing dedicated vascular training time may actually help promote research within the field of vascular surgery.

  6. Learning style preferences of surgical residency applicants. (United States)

    Kim, Roger H; Gilbert, Timothy


    The learning style preferences of general surgery residents have been previously reported; there is evidence that residents who prefer read/write learning styles perform better on the American Board of Surgery In-Training Examination (ABSITE). However, little is known regarding the learning style preferences of applicants to general surgery residency and their impact on educational outcomes. In this study, the preferred learning styles of surgical residency applicants were determined. We hypothesized that applicant rank data are associated with specific learning style preferences. The Fleming VARK learning styles inventory was offered to all general surgery residency applicants that were interviewed at a university hospital-based program. The VARK model categorizes learners as visual (V), aural (A), read/write (R), kinesthetic (K), or multimodal (MM). Responses on the inventory were scored to determine the preferred learning style for each applicant. Applicant data, including United States Medical Licensing Examination (USMLE) scores, class rank, interview score, and overall final applicant ranking, were examined for association with preferred learning styles. Sixty-seven applicants were interviewed. Five applicants were excluded due to not completing the VARK inventory or having incomplete applicant data. The remaining 62 applicants (92%) were included for analysis. Most applicants (57%) had a multimodal preference. Sixty-nine percent of all applicants had some degree of preference for kinesthetic learning. There were statistically significant differences between applicants of different learning styles in terms of USMLE step 1 scores (P = 0.001) and USMLE step 2 clinical knowledge scores (P = 0.01), but not for class ranks (P = 0.27), interview scores (P = 0.20), or final ranks (P = 0.14). Multiple comparison analysis demonstrated that applicants with aural preferences had higher USMLE 1 scores (233.2) than those with kinesthetic (211.8, P = 0.005) or multimodal

  7. An intensive vascular surgical skills and simulation course for vascular trainees improves procedural knowledge and self-rated procedural competence. (United States)

    Robinson, William P; Doucet, Danielle R; Simons, Jessica P; Wyman, Allison; Aiello, Francesco A; Arous, Elias; Schanzer, Andres; Messina, Louis M


    Surgical skills and simulation courses are emerging to meet the demand for vascular simulation training for vascular surgical skills, but their educational effect has not yet been described. We sought to determine the effect of an intensive vascular surgical skills and simulation course on the procedural knowledge and self-rated procedural competence of vascular trainees and to assess participant feedback regarding the course. Participants underwent a 1.5-day course covering open and endovascular procedures on high-fidelity simulators and cadavers. Before and after the course, participants completed a written test that assessed procedural knowledge concerning index open vascular and endovascular procedures. Participants also assessed their own procedural competence in open and endovascular procedures on a 5-point Likert scale (1: no ability to perform, 5: performs independently). Scores before and after the course were compared among postgraduate year (PGY) 1-2 and PGY 3-7 trainees. Participants completed a survey to rate the relevance and realism of open and endovascular simulations. Fifty-eight vascular integrated residents and vascular fellows (PGY 1-7) completed the course and all assessments. After course participation, procedural knowledge scores were significantly improved among PGY 1-2 residents (50% correct before vs 59% after; P educational effect.

  8. Impact of Residents on Surgical Outcomes in High-Complexity Procedures. (United States)

    Ferraris, Victor A; Harris, Jennifer W; Martin, Jeremiah T; Saha, Sibu P; Endean, Eric D


    There are different views on the effects of resident involvement on surgical outcomes. We hypothesized that resident participation in surgical care does not appreciably alter outcomes. We analyzed an American College of Surgeons NSQIP subset of inpatients having procedures with high complexity, including 4 surgical specialties (general surgery, cardiothoracic surgery, neurosurgery, and vascular surgery) with the highest mean work relative value units. We evaluated surgical outcomes in patients having procedures performed by the attending surgeon alone, or by the attending surgeon with assistance from at least one surgical resident (PGY1 to PGY≥6). Outcomes measures included operative mortality, composite morbidity, and failure to rescue (FTR). Propensity-score matching minimized the effects of nonrandom assignment of residents to procedures. In 266,411 patients, unmatched comparisons showed significantly higher operative mortality and composite morbidity rates, but decreased FTR, in operations performed with resident involvement. After propensity-score matching, there were small but significant resident-related increases in composite morbidity, but significant improvement in FTR. Senior-level resident involvement translated into improved outcomes, especially in cardiothoracic surgery procedures where >63.6% of procedures had PGY≥6 resident involvement. Resident involvement attenuated the significant worsening of operative mortality and FTR associated with multiple serious complications in individual patients. Measures of resource use increased modestly with resident involvement. We found substantial improvement in FTR with resident involvement, both in unmatched and propensity-matched comparisons. Senior-level resident participation seemed to attenuate, and even improve, surgical outcomes, despite slightly increased resource use. These results provide some reassurance about teaching paradigms.

  9. The surgical residency baby boom: changing patterns of childbearing during residency over a 30-year span. (United States)

    Smith, Caitlin; Galante, Joseph M; Pierce, Jonathan L; Scherer, Lynette A


    Birthrates during surgical residency appear to be rising. One assumption is that this is due to changes in the structure of surgical residencies. The purpose of our study was to explore whether an increase in birthrates has occurred and the reasons for this. We conducted an anonymous survey of current residents and alumni from 1976 to 2009 at a single university-based surgery training program. Alumni (46 of 116) and current residents (38 of 51) were surveyed, and our response rate was approximately 50% (84 of 167). Respondents were grouped into cohorts based on their residency start year. The early cohort consisted of residents starting residency between 1976 and 1999, and the late cohort consisted of residents starting residency between 2000 and 2009. The percentage of male residents with children during residency training was similar for the early and late cohorts (34% [10 of 29] versus 41% [9 of 22]). For female residents, there was a substantial increase in childbearing for the late cohort (7% [1 of 15] versus 35% [6 of 18]). Fifty-two percent (44 of 84) of the respondents who had children during residency reported that work hours and schedule had a negative effect on their decision to have children. Most respondents reported that availability or cost of child care, impact on residency, support from the program, increased length of training, or availability of family leave did not factor as concerns. Childbearing during residency has increased in female residents in our study. Surgical residency programs may need to accommodate this change if they want to continue to recruit and retain talented residents.

  10. Ultrasound training in surgical residency: Is it feasible?

    Full Text Available Purpose: Ultrasound training for the surgical residents is not a common practice in India. This study was undertaken to prepare a working model for surgical trainees and assess its effectiveness by training a single surgical resident. Materials and Methods: This was a prospective study of 238 patients with pain abdomen. Training was given in abdominal ultrasound for a period of 2 months. Ultrasound scans were performed independently by a radiology resident and surgery resident. Inter-rater agreement between both residents was assessed using Kappa coefficient. Ultrasound results were compared with clinical diagnosis and final diagnosis. Results: The kappa agreement was 0.53, 0.56, 0.8 and 1 for urolithiasis, appendicitis, pancreatitis and urinary tract infection, respectively. Almost all cases of cholelithiasis were identified by the surgery resident. There was improvement of 21%, 31% and 100% in patients of urolithiasis, acute appendicitis and liver abscess, respectively, in the second 10 months of the study. Conclusions: Ultrasound scans can be performed by a surgery resident with similar results as that of a radiology resident. Training of the surgery resident is possible with satisfactory results.

  12. Mohs Surgical Reconstruction Educational Activity: a resident education tool. (United States)

    Croley, Julie A; Malone, C Helen; Goodwin, Brandon P; Phillips, Linda G; Cole, Eric L; Wagner, Richard F


    Surgical reconstructive planning following Mohs surgery can be a difficult subject for dermatology residents to master. Prior research demonstrates that active learning is preferred and more effective compared to passive learning models and that dermatology residents desire greater complexity and volume in surgical training. We present a novel, active, problem-based learning tool for the education of Mohs reconstruction with the goal of improving residents' ability to plan surgical reconstructions. The Mohs Surgical Reconstruction Educational Activity is an active, problem-based learning activity in which residents designed repairs for planned Mohs defects prior to surgery on an iPad application or on a printed photograph. The attending Mohs surgeon reviewed the reconstructive designs, provided feedback, guided discussion, and facilitated insight into additional issues requiring further review. Residents performed or observed the Mohs and reconstructive surgical procedures for respective repairs. Surveys were administered to participants before and after participating in the Mohs Surgical Reconstruction Educational Activity to assess the educational value of the activity. Survey responses were recorded on a 5-point Likert scale. Mean participant-reported confidence in flap and graft knowledge, flap and graft planning, and flap and graft performance increased 1.50-2.50 Likert scale points upon completion of the Mohs surgery rotation by residents participating in the educational activity. The observed trend was larger in the dermatology resident subset, with increases of 2.00-3.50 Likert scale points reported for these questions. Mean participant-reported likelihoods of performing flaps and grafts in the future increased 0.25-0.50 Likert scale points among all residents participating in the educational activity and 0.50-1.00 Likert scale points in the dermatology resident subset. All residents participating in the educational activity somewhat or completely agreed

    To evaluate surgical theater learning environment perception in urology residents in Saudi Arabia and to investigate association of learning environment perception and stages of residency program, sectors of health care system, and regions of Saudi Arabia. A cross-sectional survey using the surgical theater educational environment measure (STEEM) inventory. The STEEM inventory was used to measure theater learning environment perception of urology residents in Saudi Arabia. Respondents' perception was compared regarding different residency stages, sectors of the health care system, and regions of Saudi Arabia. Internal reliability of the inventory was assessed using the Cronbach α coefficient. Correlation analysis was done using the Spearman ρ coefficient. Of 72 registered residents, 33 (45.8%) completed the questionnaire. The residents perceived their environment less than acceptable (135.9 ± 16.7, 67.95%). No significant differences in perception were found among residents of different program stages, different sectors of health care system, or different regions in Saudi Arabia. Residents from the eastern region perceived the training and teaching domain better (p = 0.025). The inventory showed a high internal consistency with a Cronbach α of 0.862. STEEM survey is an applicable and reliable instrument for assessing the learning environment and training skills of urology residency program in Saudi Arabia. Urology residents in Saudi Arabia perceived the theater learning environment as less than ideal. The perceptions of theater learning environment did not change significantly among different stages of the program, different sectors of health care system, or different training regions of Saudi Arabia assuring the uniformity of urology training all over Saudi Arabia. The training programs should address significant concerns and pay close attention to areas in surgical theater educational environment, which need development and enhancement, mainly planned fashion

  15. Adult Vascular Wall Resident Multipotent Vascular Stem Cells, Matrix Metalloproteinases, and Arterial Aneurysms

    Directory of Open Access Journals (Sweden)

    Bruno Amato


    Full Text Available Evidences have shown the presence of multipotent stem cells (SCs at sites of arterial aneurysms: they can differentiate into smooth muscle cells (SMCs and are activated after residing in a quiescent state in the vascular wall. Recent studies have implicated the role of matrix metalloproteinases in the pathogenesis of arterial aneurysms: in fact the increased synthesis of MMPs by arterial SMCs is thought to be a pivotal mechanism in aneurysm formation. The factors and signaling pathways involved in regulating wall resident SC recruitment, survival, proliferation, growth factor production, and differentiation may be also related to selective expression of different MMPs. This review explores the relationship between adult vascular wall resident multipotent vascular SCs, MMPs, and arterial aneurysms.

  16. The emotional intelligence of surgical residents: a descriptive study. (United States)

    Jensen, Aaron R; Wright, Andrew S; Lance, Avalon R; O'Brien, Kurt C; Pratt, Charles D; Anastakis, Dimitri J; Pellegrini, Carlos A; Horvath, Karen D


    We assessed educational needs with regard to leadership, communication, and emotional intelligence (EI) among surgical residents. General surgery residents (n = 74) were examined using the BarOn Emotional Quotient Inventory (EQ-i) and a 20-item survey. Residents believed that leadership skills were important (mean 4.7, SD .5) and that they had skills in each the five EI areas (overall mean 4.1, SD .8). Both the overall group's EQ-i scores (mean 106.6, SD 11.6), as well as scores on the 20 components of the EQ-i (range of means 102-110), were higher than national norms. Individuals varied substantially on EQ-i subscale scores. Surgical residents believed that leadership skills are important and scored strongly on both an EI self-assessment and the EQ-i. Specific individual differences in subscale scores can potentially identify areas for direct educational intervention.

  18. Extremes in Otolaryngology Resident Surgical Case Numbers: An Update. (United States)

    Baugh, Tiffany P; Franzese, Christine B


    Objectives The purpose of this study is to examine the effect of minimum case numbers on otolaryngology resident case log data and understand differences in minimum, mean, and maximum among certain procedures as a follow-up to a prior study. Study Design Cross-sectional survey using a national database. Setting Academic otolaryngology residency programs. Subjects and Methods Review of otolaryngology resident national data reports from the Accreditation Council for Graduate Medical Education (ACGME) resident case log system performed from 2004 to 2015. Minimum, mean, standard deviation, and maximum values for total number of supervisor and resident surgeon cases and for specific surgical procedures were compared. Results The mean total number of resident surgeon cases for residents graduating from 2011 to 2015 ranged from 1833.3 ± 484 in 2011 to 2072.3 ± 548 in 2014. The minimum total number of cases ranged from 826 in 2014 to 1004 in 2015. The maximum total number of cases increased from 3545 in 2011 to 4580 in 2015. Multiple key indicator procedures had less than the required minimum reported in 2015. Conclusion Despite the ACGME instituting required minimum numbers for key indicator procedures, residents have graduated without meeting these minimums. Furthermore, there continues to be large variations in the minimum, mean, and maximum numbers for many procedures. Variation among resident case numbers is likely multifactorial. Ensuring proper instruction on coding and case role as well as emphasizing frequent logging by residents will ensure programs have the most accurate data to evaluate their case volume.

  19. Opioid Prescribing Education in Surgical Residencies: A Program Director Survey. (United States)

    Yorkgitis, Brian K; Bryant, Elizabeth; Raygor, Desiree; Brat, Gabriel; Smink, Douglas S; Crandall, Marie


    Opioid abuse and misuse is a public health crisis. A national effort to reduce this phenomenon is ongoing. Residents represent a large pool of opioid prescribers but, are often not the target for opioid prescribing education (OPE). We developed a survey to assess current opioid prescribing practices and education among surgical residents. An Institutional Review Board and Association of Program Directors in Surgery approved survey was electronically mailed to surgical program directors (PDs). The survey included questions regarding residency type, location, number of graduates per year, perceived value of OPE, residency policy on prescribing outpatients controlled substances, presence of OPE, and preferred method of OPE. A total of 248 PDs were e-mailed the survey with 110 complete responses (44.4%). Of all 104 (94.5%) allow residents to prescribe outpatient opioids with 24 (23.1%) limiting the opioid class prescribed. A total of 29 (27.9%) programs require residents to obtain their own Drug Enforcement Administration registration. Only 22 (20.0%) programs had in place mandatory OPE, 7 (6.4%) PDs were unsure if OPE was a mandatory educational requirement. Furthermore, 70 (79.5%) of programs currently without OPE are considering adding it. Didactic lecture (18, 81.8%) is the most common modality for OPE. The mode time dedicated to OPE was 1 hour. When PDs were asked about which method would be best to deliver OPE, the most common response was case-based scenarios (39, 35.5%). Bivariate statistics were performed and no association was found between OPE and program characteristics'. Most surgical residency programs allow residents to prescribe outpatient opioids, very few require OPE. The most common method of OPE was didactic lectures. To enhance a resident's knowledge in prescribing opioids, programs should incorporate OPE into their curriculum. Copyright © 2017 Association of Program Directors in Surgery.

  20. General Surgery Resident Vascular Operative Experience in the Era of Endovascular Surgery and Vascular Fellowships. (United States)

    Yan, Huan; Maximus, Steven; Kim, Jerry J; Smith, Brian; Kim, Dennis; Koopmann, Matthew; DeVirgilio, Christian


    Advances in endovascular surgery have resulted in a decline in major open arterial reconstructions nationwide. Our objective is to investigate the effect of endovascular surgery on general surgery resident experience with open vascular surgery. Between 2004 and 2014, 112 residents graduated from two academic institutions in Southern California. Residents were separated into those who graduated in 2004 to 2008 (period 1) and in 2009 to 2014 (period 2). Case volumes of vascular procedures were compared using two-sample t test. A total of 43 residents were in period 1 and 59 residents were in period 2. In aggregate, there was no significant difference in open cases recorded between the two periods (84 vs 87, P = 0.194). Subgroup analysis showed period 2 recorded significantly fewer cases of open aneurysm repair (5 vs 3, P surgery residents experienced a significant decline in several index open major arterial reconstruction cases. This decline was offset by maintenance of dialysis access procedures. If the trend continues, future general surgeons will not be proficient in open vascular procedures.

  2. Canadian vascular surgery residents' perceptions regarding future job opportunities. (United States)

    Cooper, Joel A; Dubois, Luc; Power, Adam H; DeRose, Guy; MacKenzie, Kent S; Forbes, Thomas L


    The objective was to determine the employment environment for graduates of Canadian vascular surgery training programs. A cross-sectional survey of residents and graduates (2011-2012) was used. Thirty-seven residents were invited with a response rate of 57%, and 14 graduates with a response rate of 71%; 70% of graduates felt the job market played an important role in their decision to pursue vascular surgery as a career compared to 43% of trainees. The top three concerns were the lack of surgeons retiring, the overproduction of trainees, and saturation of the job market. The majority (62%) of trainees see themselves extending their training due to lack of employment. All of the graduates obtained employment, with 50% during their second year (of two years) of training and 30% after training was completed. Graduates spent an average of 12 ± 10.6 months seeking a position and applied to 3.3 ± 1.5 positions, with a mean of 1.9 ± 1.3 interviews and 2 ± 1.2 offers. There was a discrepancy between the favorable employment climate experienced by graduates and the pessimistic outlook of trainees. We must be progressive in balancing the employment opportunities with the number of graduates. Number and timing of job offers is a possible future metric of the optimal number of residents.

  3. Surgical resident learning styles have changed with work hours. (United States)

    Quillin, Ralph C; Cortez, Alexander R; Pritts, Timothy A; Hanseman, Dennis J; Edwards, Michael J; Davis, Bradley R


    The Accreditation Council for Graduate Medical Education instituted the 80-h workweek for residency programs in 2003. This presented a unique challenge for surgery residents who must acquire a medical and technical knowledge base during training. Therefore, learning should be delivered in an environment congruent with an individual's learning style. In this study, we evaluated the learning styles of general surgery residents to determine how learning styles changed after the implementation to the 80-h workweek. Kolb learning style inventory was taken by general surgery residents at the University of Cincinnati's Department of Surgery, and results from 1999-2012 were analyzed. Statistical analysis was performed using the chi-squared, logistic regression and Wilcoxon rank-sum test. Significance was defined as a P value of learning styles after the institution of the 80-h workweek to converging (43.9%) and accommodating (40.4%, P learning. This change paralleled the transition to a more team-based approach to patient care with the implementation of the 80-h workweek. These findings are important for surgical educators to consider in the development of surgical resident curriculum. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background Vascular rings are uncommon anomalies in which preferred strategies for diagnosis and management may vary among institutions.In this study,we reported our approach and a review of our 5-year experience.Methods From May 2006 to April 2011,45 children (31 boys) with vascular rings underwent surgical repair at Beijing Children's Hospital.Nineteen patients (26%) had associated heart anomalies.Results There were two hospital deaths.At follow-up,11 patients still had intermittent respiratory symptoms,but these symptoms had no effect on growth or physical activities.No patients required reoperation.Conclusions The rates of misdiagnosis and missed diagnosis of vascular rings are higher than those of other congenital heart diseases.A high index of clinical suspicion coupled with the use of computed tomography enables early diagnosis.Surgical repair can be performed successfully,although a number of patients will have persistent symptoms.

  5. Pneumatic tourniquet for surgical procedures of hemodialysis vascular access. (United States)

    Wang, Shouwen


    Pneumatic tourniquet has been frequently utilized in various surgical specialties to facilitate surgical procedures on the extremities. However, its use for surgical procedures of hemodialysis access has been limited to some surgeons in the United States and often confined to the hospital settings under general anesthesia or regional nerve block. We have successfully employed a pneumatic tourniquet system for surgical procedures of hemodialysis access under conscious sedation and local anesthesia in an outpatient setting. Because prolonged tourniquet inflation is associated with ischemic pain and other potential complications, we have limited the continuous inflation time to pneumatic tourniquet use is well tolerated under conscious sedation and not associated with significant adverse events. These and other reported data suggest that pneumatic tourniquet can reduce procedure time, minimize required dissection, reduce vascular trauma by eliminating vascular clamps and potentially improve the outcomes of surgical procedures of hemodialysis access. These advantages may be translated into cost savings for hemodialysis access care. This review discusses practical issues of pneumatic tourniquet use and its applications in surgical procedures of hemodialysis access. © 2014 Wiley Periodicals, Inc.

  6. Games as teaching tools in a surgical residency. (United States)

    Meterissian, Sarkis; Liberman, Moishe; McLeod, Peter


    Didactic lectures have been the mainstay of core teaching in the surgical residency program at our school. Our concerns about the educational impact of these passive activities led us to consider more interactive teaching approaches. We developed an interactive games-based approach to learning. One set of games was labeled "Who wants to be a Surgeon" (WS) and the other was called "Senior Face-off" (SF). We evaluated the impact of this innovation using an end-of-year questionnaire. Enjoyment, teaching quality and preference over lectures were high for both games. However, the WS sparked interest significantly more in junior residents (4.3 +/- 0.21 vs 3.3 +/- 0.31, p = 0.015) and senior residents found both games more stressful than did junior residents (WS: 2.88 +/- 0.32 vs 2.00 +/- 0.21, p = 0.038, and SF: 3.54 +/- 0.29 vs 1.80 +/- 0.33, p = 0.001). This innovative teaching technique promoted learner interest and was regarded as a worthwhile educational activity. Games with a competitive emphasis may unduly stress senior residents.

  7. Under the microscope: assessing surgical aptitude of otolaryngology residency applicants. (United States)

    Carlson, Matthew L; Archibald, David J; Sorom, Abraham J; Moore, Eric J


    Application to otolaryngology residency is a highly competitive process. Programs identify the best candidates by evaluating academic performance in medical school, board scores, research experience, performance during an interview, and letters of recommendation. Unfortunately, none of these metrics completely assess an applicant's capacity to learn and perform surgical skills. We describe a direct assessment of an applicant's ability for rapid surgical skill acquisition, manual dexterity, and response to stress that can be performed during the interview process. A retrospective study at an academic otolaryngology residency program. After orientation, applicants were seated at a microsurgical training station and allotted 20 minutes to suture an incision using 10-0 nylon suture on a latex practice card. Their performance was graded using a 1-to-5 scoring system for the following categories: microscope use, respect for tissue, instrument handling, knot tying and suture control, skills acquisition, and attitude toward the exercise. Applicants were given some instruction and assessed on their ability to incorporate what they had learned into their technique. The average total applicant score was 23.2, standard deviation (SD) 3.6 (maximum 30); 13.4% of applicants scored 1 SD above the mean. The value of applicant screening tests in predicting surgical competency is controversial. We describe a direct assessment tool that may prove useful in identifying outliers, both high and low, to aid in final applicant ranking.

    The field of vascular anomalies presents diverse challenges in diagnosis and management. Although many lesions involve the head and neck, training in vascular anomalies is not universally included in otolaryngology residencies and pediatric otolaryngology (POTO) fellowships. To explore the education in, exposure to, and comfort level of otolaryngology trainees with vascular anomalies. A survey was distributed to 39 POTO fellows and 44 residents in postgraduate year 5 who matched into POTO fellowships from April 22 through June 16, 2014. Survey responses from trainees on exposure to, education on, and comfort with vascular anomalies. Forty-four residents in postgraduate year 5 who applied to POTO fellowships and 39 POTO fellows were emailed the survey. Fourteen respondents were unable to be contacted owing to lack of a current email address. Thirty-six of 69 residents and fellows (18 fellows and 18 residents [52%]) responded to the survey. Twenty-seven trainees (75%) reported no participation in a vascular anomalies clinic during residency; 6 of these 27 individuals (22%) trained at institutions with a vascular anomalies clinic but did not participate in the clinic, and 28 of the 36 respondents (78%) reported that they had less than adequate or no exposure to vascular anomalies in residency. Among POTO fellows, 11 of 17 (65%) did not participate in a vascular anomalies clinic during fellowship, even though 8 of the 11 had a vascular anomalies clinic at their fellowship program. During fellowship training, 12 of 18 fellows (67%) reported that they had adequate exposure to vascular anomalies. Only 20 respondents (56%) felt comfortable distinguishing among diagnoses of vascular anomalies, and only 4 residents (22%) and 9 fellows (50%) felt comfortable treating patients with vascular anomalies. All fellows believed that training in vascular anomalies was important in fellowship, and 100% of respondents indicated that increased exposure to diagnosis and management of

    Full Text Available Background. Vascular anomalies in the hand do not occur frequently. Their presence in the metacarpal region can cause different functional disorders. The extent of such disorders directly depends on the localization and size of vascular anomalies, duration and the nature of the anomaly growth as well as on eventual secondary complications such as ulceration or bleeding. The aim of this case report was to show the specifics in the clinical picture, pathogenesis and evolution of such anomalies, applied diagnostic procedures (radiography, ultrasound, magnetic resonance, electromyography and surgical treatment as well as postoperative functional results. Case report. In the Clinic for Plastic Surgery and Burns, Military Medical Academy Belgrade, two patients were treated surgically for vascular anomalies of the middle palmar region of the hand. The first patient, a 36-year-old male, a former active sportsman (professional handball player was treated for acute increase in the vascular anomaly of hand in the metacarpal region and proximal phalange of III and IV fingers of his right hand. The anomaly was detected 6 months prior to his hospitalization while two weeks before the hospitalization there was a sudden growth and increase in the change. The second case, a 15-year-old male patient actively pursuing a career in professional basketball was treated for a tumor localized in the metacarpal zone of his left hand. According to the information provided by his parents, the anomaly had been present since his birth. Initially, the anomaly manifested itself as a discoloration of the skin with a marked capillary drawing, gradually increasing throughout the last five years to the present dimension. The growth of the malformation was noticed to coincide in both patients with more active pursuit of their professional sports career. Conclusion. The clinical picture of hand vascular anomalies is dominated by the symptoms of compression of neurovascular

  10. Vascular surgical education in a medium-income country. (United States)

    Abdool-Carrim, A T O; Veller, M G


    Medium income country such as South Africa face a dilemma on the need to offer high quality vascular surgical care in a resource constrained environment, where the vast majority of population has inadequate access to even the most basic health care provision. At the same time with rapid development in technology there is also the need to provide high technological treatment to a small population that can afford high cost therapy. This apparent dichotomy in health care provides a challenge and the solution is for all role players in the health care provision to find a solution which will suite the population at large.

  11. General versus vascular surgeon: impact of a vascular fellowship on clinical practice, surgical case load, and lifestyle. (United States)

    Franz, Randall W


    An applicant shortage for vascular surgery (VS) residencies exists despite an increase in available training positions created to meet the growing demands for vascular surgeons. After 3 years of practice as an American Board of Surgery (ABS)-certified/board-eligible general surgeon, the author of this study attended an accredited 1-year VS training fellowship and received an ABS certificate of Added Qualifications in VS. The purpose of this review was to investigate the implications completing a vascular fellowship has had on VS procedure patterns, vascular procedure competency, clinical practice, career, and lifestyle with the aim of attracting trainees to the field of VS. The author's operative logs were reviewed retrospectively to summarize vascular procedures performed before and after the vascular fellowship. Statistical analysis was performed comparing the types and volume of vascular procedures before and after the vascular fellowship. Changes in professional career and personal life also were examined. The author performed 401 vascular procedures during 2.8 years as a general surgeon. In the first 3.4 years after the vascular fellowship, vascular procedure volume increased to 1563. The mean number of vascular procedures performed per year increased from 143.2 as a general surgeon to 459.7 as a vascular surgeon. The three major differences in vascular procedures occurring after the vascular fellowship were (1) a threefold increase in the number of vascular procedures performed, (2) a shift from major open to venous and endovascular procedures, and (3) an increase in case complexity. Specializing in VS also has resulted in increased career opportunities, more career satisfaction, a direct financial benefit, and more flexibility for lifestyle and family. Because of these positive changes, the author encourages medical students and residents interested in VS to explore the specialty early, seek vascular surgeons to serve as mentors, and enter one of the new VS

  12. Surgical resident learning styles: faculty and resident accuracy at identification of preferences and impact on ABSITE scores. (United States)

    Kim, Roger H; Gilbert, Timothy; Ristig, Kyle; Chu, Quyen D


    As a consequence of surgical resident duty hour restrictions, there is a need for faculty to utilize novel teaching methods to convey information in a more efficient manner. The current paradigm of surgical training, which has not changed significantly since the time of Halsted, assumes that all residents assimilate information in a similar fashion. However, recent data has shown that learners have preferences for the ways in which they receive and process information. The VARK model categorizes learners as visual (V), aural (A), read/write (R), and kinesthetic (K). The VARK learning style preferences of surgical residents have not been previously evaluated. In this study, the preferred learning styles of general surgery residents were determined, along with faculty and resident perception of resident learning styles. In addition, we hypothesized that American Board of Surgery In-Training Exam (ABSITE) scores are associated with preference for a read/write (R) learning style. The Fleming VARK learning styles inventory was administered to all general surgery residents at a university hospital-based program. Responses on the inventory were scored to determine the preferred learning style for each resident. Faculty members were surveyed to determine their accuracy in identifying the preferred learning style of each resident. All residents were also surveyed to determine their accuracy in identifying their peers' VARK preferences. Resident ABSITE scores were examined for association with preferred learning styles. Twenty-nine residents completed the inventory. Most (18 of 29, 62%) had a multimodal preference, although more than a third (11 of 29, 38%) demonstrated a single-modality preference. Seventy-six percent of all residents (22 of 29) had some degree of kinesthetic (K) learning, while under 50% (14 of 29) were aural (A) learners. Although not significant, dominant (R) learners had the highest mean ABSITE scores. Faculty identified residents' learning styles

  13. Learning styles of medical students, general surgery residents, and general surgeons: implications for surgical education (United States)


    Background Surgical education is evolving under the dual pressures of an enlarging body of knowledge required during residency and mounting work-hour restrictions. Changes in surgical residency training need to be based on available educational models and research to ensure successful training of surgeons. Experiential learning theory, developed by David Kolb, demonstrates the importance of individual learning styles in improving learning. This study helps elucidate the way in which medical students, surgical residents, and surgical faculty learn. Methods The Kolb Learning Style Inventory, which divides individual learning styles into Accommodating, Diverging, Converging, and Assimilating categories, was administered to the second year undergraduate medical students, general surgery resident body, and general surgery faculty at the University of Alberta. Results A total of 241 faculty, residents, and students were surveyed with an overall response rate of 73%. The predominant learning style of the medical students was assimilating and this was statistically significant (p < 0.03) from the converging learning style found in the residents and faculty. The predominant learning styles of the residents and faculty were convergent and accommodative, with no statistically significant differences between the residents and the faculty. Conclusions We conclude that medical students have a significantly different learning style from general surgical trainees and general surgeons. This has important implications in the education of general surgery residents. PMID:20591159

  16. The Use of Laparoscopy Simulation to Explore Gender Differences in Resident Surgical Confidence

    Directory of Open Access Journals (Sweden)

    Rebecca L. Flyckt


    Full Text Available Background. The objective of this study was to determine whether female surgical residents underestimate their surgical abilities relative to males on a standardized test of laparoscopic skill. Methods. Twenty-six male and female general surgery residents and 25 female obstetrics and gynecology residents at two academic centers were asked to predict their score prior to undergoing the Fundamentals of Laparoscopic Surgery standardized skills exam. Actual and predicted score as well as delta values (predicted score minus actual score were compared between residents. Multivariate linear regression was used to determine variables associated with predicted score, actual score, and delta scores. Results. There was no difference in actual score based on residency or gender. Predicted scores, however, were significantly lower in female versus male general surgery residents (25.8 ± 13.3 versus 56.0 ± 16.0; p<0.01 and in female obstetrics and gynecology residents versus male general surgery residents (mean difference 20.9, 95% CI 11.6–34.8; p<0.01. Male residents more accurately predicted their scores while female residents significantly underestimated their scores. Conclusion. Gender differences in estimating surgical ability exist that do not reflect actual differences in performance. This finding needs to be considered when structuring mentorship in surgical training programs.

  18. Still under the microscope: can a surgical aptitude test predict otolaryngology resident performance? (United States)

    Moore, Eric J; Price, Daniel L; Van Abel, Kathryn M; Carlson, Matthew L


    Application to otolaryngology-head and neck surgery residency is highly competitive, and the interview process strives to select qualified applicants with a high aptitude for the specialty. Commonly employed criteria for applicant selection have failed to show correlation with proficiency during residency training. We evaluate the correlation between the results of a surgical aptitude test administered to otolaryngology resident applicants and their performance during residency. Retrospective study at an academic otolaryngology-head and neck surgery residency program. Between 2007 and 2013, 224 resident applicants participated in a previously described surgical aptitude test administered at a microvascular surgical station. The composite score and attitudinal scores for 24 consecutive residents who matched at our institution were recorded, and their residency performance was analyzed by faculty survey on a five-point scale. The composite and attitudinal scores were analyzed for correlation with residency performance score by regression analysis. Twenty-four residents were evaluated for overall quality as a clinician by eight faculty members who were blinded to the results of surgical aptitude testing. The results of these surveys showed good inter-rater reliability. Both the overall aptitude test scores and the subset attitudinal score showed reliability in predicting performance during residency training. The goal of the residency selection process is to evaluate the candidate's potential for success in residency and beyond. The results of this study suggest that a simple-to-administer clinical skills test may have predictive value for success in residency and clinician quality. 4. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

  19. The value of resident teaching to improve student perceptions of surgery clerkships and surgical career choices. (United States)

    Whittaker, Lorin D; Estes, Norman C; Ash, Jennifer; Meyer, Lynne E


    A fundamental function of attending faculty is to teach and mentor medical students, but the benefit of the resident's role is recognized increasingly. Our Standardized Institutional Clinical Clerkship Assessment allows students to rate 27 factors relative to a clinical clerkship. Scores from 1998 to 2005 were used to evaluate our surgical clerkship program and to compare resident and attending teachers. Student surgery career choices also were monitored. Medical students routinely scored residents more highly than attending faculty. Attendings' scores did not improve; however, residents' teaching and overall clerkship scores improved during the study period and paralleled students' increased selection of a surgical career. Students perceived residents as teachers more than attendings. Residents may have significant influence over students' career choice by their teaching and mentoring activities, which benefit attending efforts.

  20. Assessment of technical and nontechnical skills in surgical residents. (United States)

    Ponton-Carss, Alicia; Kortbeek, John B; Ma, Irene W Y


    Surgical competence encompasses both technical and nontechnical skills. This study seeks to evaluate the validity evidence for a comprehensive surgical skills examination and to examine the relationship between technical and nontechnical skills. Six examination stations assessing both technical and nontechnical skills, conducted yearly for surgical trainees (n = 120) between 2010 and 2014 are included. The assessment tools demonstrated acceptable internal consistency. Interstation reliability for technical skills was low (alpha = .39). Interstation reliability for the nontechnical skills was lower (alpha range -.05 to .31). Nontechnical skills domains were strongly correlated, ranging from r = .65, P skills were inconsistent, ranging from poor (r = -.06; P = .54) to moderate (r = .45; P skills are necessary to assess overall surgical competency.

  1. Role of the Vasa Vasorum and Vascular Resident Stem Cells in Atherosclerosis

    Directory of Open Access Journals (Sweden)

    Jun-ichi Kawabe


    Full Text Available Atherosclerosis is considered an “inside-out” response, that begins with the dysfunction of intimal endothelial cells and leads to neointimal plaque formation. The adventitia of large blood vessels has been recognized as an active part of the vessel wall that is involved in the process of atherosclerosis. There are characteristic changes in the adventitial vasa vasorum that are associated with the development of atheromatous plaques. However, whether vasa vasorum plays a causative or merely reactive role in the atherosclerotic process is not completely clear. Recent studies report that the vascular wall contains a number of stem/progenitor cells that may contribute to vascular remodeling. Microvessels serve as the vascular niche that maintains the resident stem/progenitor cells of the tissue. Therefore, the vasa vasorum may contribute to vascular remodeling through not only its conventional function as a blood conducting tube, but also its new conceptual function as a stem cell reservoir. This brief review highlights the recent advances contributing to our understanding of the role of the adventitial vasa vasorum in the atherosclerosis and discusses new concept that involves vascular-resident factors, the vasa vasorum and its associated vascular-resident stem cells, in the atherosclerotic process.

    Jabbour, Jad; Bakeman, Anna; Robey, Thomas; Jabbour, Noel


    To characterize the nature of surgical preparation among otolaryngology residents nationwide, determine the self-rated effectiveness and efficiency of case preparation practices, and identify potential means for educational improvement. A survey examining the study objectives was developed and distributed to otolaryngology residents nationwide. Survey response data were submitted to descriptive analysis and comparative analyses between junior and senior residents. Literature regarding case preparation among otolaryngology residents was reviewed. Among 108 resident respondents, the most commonly used resources included textbooks (86.1%), surgical education websites (74.1%), and surgical atlases (66.7%). Time was the primary limitation (cited by 84.3%) and convenience the predominant factor influencing resource selection (92.5%). On a 5-point Likert scale, mean scores regarding effectiveness and efficiency of case preparation were 3.53 ± 0.68 and 3.19 ± 0.88, respectively. Senior residents compared to junior residents were more likely to rate their preparation as effective (3.75 ± 0.54 vs 3.40 ± 0.72, P = .008) and efficient (3.45 ± 0.85 vs 3.03 ± 0.86, P = .02). Otolaryngology residents do not consistently rate their case preparation as effective or efficient. While there appears to be progress in self-directed learning throughout residency, room for improvement remains, with potential avenues for such improvement explored here.

    Full Text Available Background : Bear mauling is rarely reported in medical literature due to its rare occurrence. Present study was undertaken to describe the pattern and management of bear maul vascular injuries in Kashmir. Methods : Study of patients with bear maul vascular injury from 1st Jan 2004 to 31st Dec. 2008. Fifteen patients with bear maul vascular injury were studied. All patients of bear maul without vascular injury were excluded from the study. Results : Most of the patients were treated by reverse saphenous vein graft or end to end anastomosis. Most common complication was wound infection (20% followed by graft occlusion (13.33%. There was no operative death. Conclusion : Bear attacks are very common in Kashmir. Vascular injury due to bear maul needs prompt resuscitation and revascularization. Results are very good provided timely intervention for revascularization is done.

  4. Perceptions of Intimate Partner Violence: a cross sectional survey of surgical residents and medical students

    David J. Mathews


    Full Text Available BACKGROUND: Intimate partner violence (IPV is an important health issue. Many medical students and residents have received training relating to IPV, but previous studies show that many students feel that their training has been inadequate. Our objective was to assess the knowledge, attitudes and perceptions about IPV among university medical students and surgical residents. METHODS: We administered an online survey to a sample of Ontario medical students and surgical residents. The survey instrument was a modified version of the Provider Survey. RESULTS: Two hundred medical students and surgical residents participated in the survey (response rate: 29%. Misperceptions about IPV among respondents included the following: 1 victims must get something from the abusive relationships (18.2%, 2 physicians should not interfere with a couple’s conflicts (21%, 3 asking about IPV risks offending patients (45%, 4 Victims choose to be victims (11.1%, 5 it usually takes ‘two to tango’ (18.3%, and 6 some patients’ personalities cause them to be abused (41.1%. The majority of respondents (75.0% believed identifying IPV was very relevant to clinical practice. The majority of medical students (91.2% and surgical residents (96.9% estimated the IPV prevalence in their intended practice to be 10% or less. Most of the medical students (84% and surgical residents (60% felt that their level of training on IPV was inadequate and over three quarters of respondents (77.2% expressed a desire to receive additional education and training on IPV. CONCLUSIONS: There are misconceptions among Canadian medical students and surgical residents about intimate partner violence. These misconceptions may stem from lack of education and personal discomfort with the issue or from other factors such as gender. Curricula in medical schools and surgical training programs should appropriately emphasize educational opportunities in the area of IPV.

    Rouch, Joshua D; Wagner, Justin P; Scott, Andrew; Sullins, Veronica F; Chen, David C; DeUgarte, Daniel A; Shew, Stephen B; Tillou, Areti; Dunn, James C Y; Lee, Steven L


    General surgery residents lack a standardized educational experience in pediatric surgery. We hypothesized that the development of a mobile educational interface would provide general surgery residents broader access to pediatric surgical education materials. We created an educational mobile website for general surgery residents rotating on pediatric surgery, which included a curriculum, multimedia resources, the Operative Performance Rating Scale (OPRS), and Twitter functionality. Residents were instructed to consult the curriculum. Residents and faculty posted media using the Twitter hashtag, #UCLAPedSurg, and following each surgical procedure reviewed performance via the OPRS. Site visits, Twitter posts, and OPRS submissions were quantified from September 2013 to July 2014. The pediatric surgery mobile website received 257 hits; 108 to the homepage, 107 to multimedia, 28 to the syllabus, and 19 to the OPRS. All eligible residents accessed the content. The Twitter hashtag, #UCLAPedSurg, was assigned to 20 posts; the overall audience reach was 85 individuals. Participants in the mobile OPRS included 11 general surgery residents and 4 pediatric surgery faculty. Pediatric surgical education resources and operative performance evaluations are effectively administered to general surgery residents via a structured mobile platform.

  8. Intrahepatic Vascular Anatomy in Rats and Mice--Variations and Surgical Implications.

    Directory of Open Access Journals (Sweden)

    Constanze Sänger

    Full Text Available The intra-hepatic vascular anatomy in rodents, its variations and corresponding supplying and draining territories in respect to the lobar structure of the liver have not been described. We performed a detailed anatomical imaging study in rats and mice to allow for further refinement of experimental surgical approaches.LEWIS-Rats and C57Bl/6N-Mice were subjected to ex-vivo imaging using μCT. The image data were used for semi-automated segmentation to extract the hepatic vascular tree as prerequisite for 3D visualization. The underlying vascular anatomy was reconstructed, analysed and used for determining hepatic vascular territories.The four major liver lobes have their own lobar portal supply and hepatic drainage territories. In contrast, the paracaval liver is supplied by various small branches from right and caudate portal veins and drains directly into the vena cava. Variations in hepatic vascular anatomy were observed in terms of branching pattern and distance of branches to each other. The portal vein anatomy is more variable than the hepatic vein anatomy. Surgically relevant variations were primarily observed in portal venous supply.For the first time the key variations of intrahepatic vascular anatomy in mice and rats and their surgical implications were described. We showed that lobar borders of the liver do not always match vascular territorial borders. These findings are of importance for the design of new surgical procedures and for understanding eventual complications following hepatic surgery.

    Knowledge concerning palliative care and the associated skills, including effective pain control, is essential for surgeons who treat cancer patients in daily practice. This study focuses on a palliative care training course that has been mandatorily conducted for all surgical residents of our hospital since 2009. We evaluated the effectiveness of our mandatory palliative care training course by conducting a retrospective study of the patients' medical records and participants' questionnaire results and discussed the importance of palliative care education for surgical residents. All 12 surgical residents who participated in the course in 2009 had graduated 4-9 years back. They were assigned to look after a total of 92 cases (average, 7.66 cases per resident) during the course. The purpose of care in most cases (92.3%) was to mitigate pain. Introducing analgesic adjuvants such as gabapentin or amitriptyline accounted for the largest part of initial interventions (23.9%) aimed at controlling cancer pain, followed by changes in route of administration or doses of prior opioid analgesics (21.7%). Interventions with opioid analgesics were conducted most frequently (47.7%). The overall pain improvement rate was 89.1%. We used a questionnaire after the course to evaluate its effectiveness. The surgical residents stated that it was a meaningful course through which they gained practical knowledge on palliative care and that the experience would change their approach to home care.

  15. Quality improvement initiative: Preventative Surgical Site Infection Protocol in Vascular Surgery. (United States)

    Parizh, David; Ascher, Enrico; Raza Rizvi, Syed Ali; Hingorani, Anil; Amaturo, Michael; Johnson, Eric


    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 surgical 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.

  16. Residents' perceptions of implant surgical training in advanced education in prosthodontic programs. (United States)

    Yuan, Judy Chia-Chun; Lee, Damian J; Knoernschild, Kent L; Campbell, Stephen D; Sukotjo, Cortino


    The purpose of this study was to assess residents' perspectives on their implant surgical training in Advanced Education in Prosthodontic programs in the United States. Questionnaires were distributed to all prosthodontic residents (N = 442). The 27 questions assessed the subjective and objective aspects of implant surgical training from the view of prosthodontic residents. The data were compiled and reported as frequencies. Descriptive statistics were used to analyze the data. One hundred and ninety-eight responses (44.8%) were received and analyzed. Forty-seven percent (94) of the respondents felt that the philosophy of their programs regarding implant placement in prosthodontics was "optional but encouraged," whereas 30% (60) felt that it was "mandatory." The majority of the respondents (73%, 144) stated that their programs allowed them to place implants for their own patients. For those respondents who placed their own implants, 40% (58) of them indicated that the level of their clinical training was "competent." Almost half of the respondents expressed that they would like to have a proficient level of clinical training in implant surgery by the completion of their residency programs. Forty-four percent (87) of the respondents felt their residency training adequately prepared them for implant surgery, whereas the other 37% (73) did not. For those who did not, 74% (55) felt their residency programs should have prepared them for implant surgical training. The current generation of prosthodontic residents has an opportunity to place implants in their programs and would like to be trained in surgical aspects of implant dentistry at the level of competency or higher. © 2010 by The American College of Prosthodontists.

  17. Vascular Endograft Infection with Listeria monocytogenes reated with Surgical Debridement but without Graft Removal

    Beate Tanner-Steinmann


    Full Text Available The awareness of Listeria monocytogenes as a pathogen in meningitis and bacteremia in immunosuppressed patients is high. We report a case of vascular graft infection due to Listeria monocytogenes as an example of a less well-known manifestation of listeriosis and focus on the possible treatment procedures emphasizing a management with surgical debridement but preservation of the endograft, in contrast to the gold standard treatment of vascular graft infections which consists of a removal of the graft.

  18. Trends in operative experience of pediatric surgical residents in the United States and Canada. (United States)

    Fingeret, Abbey L; Stolar, Charles J H; Cowles, Robert A


    Expansion of the number of training programs in pediatric surgery occurred from 2003 through 2010. We sought to determine the effect of program expansion on case volume and distribution of operative experience. Public domain data on pediatric surgery resident summary statistics available from the Accreditation Council for Graduate Medical Education (ACGME) from July 2003 through June 2010 were analyzed. Total case volume as primary surgeon or teaching assistant, mean case volume per resident, standard deviation, mode, minimum, and maximum number of cases per resident were evaluated. Mean total cases per resident, minimally invasive laparoscopic and thoracoscopic cases, and requisite cases as defined by the ACGME categories of: tumor, important pediatric surgical, and neonatal cases were analyzed by a Cuzick Wilcoxon-type nonparametric trend statistic using a significance level of 0.05. Skew was assessed by Pearson coefficient with levels of -0.5 to 0.5 defining a parametric distribution. The number of pediatric surgical training residents increased by 42% during the years reported, from 24 to 34. No statistically significant difference was found in the mean number of total cases or requisite cases per resident. The mean volume of minimally invasive procedures increased significantly. Case volume per resident was non-parametrically distributed with increasing positive skew over time. The increase in number of pediatric surgical resident training positions has not adversely affected overall operative experience or exposure to highly specialized requisite cases, on average. The increasing positive skew of total and index cases, however, suggests that variability between programs in case exposure is increasing over time. Copyright © 2013 Elsevier Inc.

    Pancreatic cancer is associated with a poor prognosis,and surgical resection remains the only chance for curative therapy.In the absence of metastatic disease,which would preclude resection,assessment of vascular invasion is an important parameter for determining resectability of pancreatic cancer.A frequent error is to misdiagnose an involved major vessel.Obviously,surgical exploration with pathological examination remains the"gold standard"in terms of evaluation of resectability,especially from the point ...

  20. Surgical residency training in the mission setting: current status and future directions

    Directory of Open Access Journals (Sweden)

    James D Smith


    Full Text Available Surgery has traditionally been an important aspect of services offered by mission hospitals, but only in the last 20 years has surgical residency training been incorporated into the mission hospital setting. A working group of surgical educators met in conjunction with the Global Missions Health Conference in November 2015 and discussed the current status of surgical training in the mission setting. This paper outlines the current status and makes recommendations for mission groups who are contemplating starting a residency training program. Potential difficulties and the importance of regional recognition of the program are discussed. The work group felt that it was important to include a strong spiritual emphasis as part of the training. Future directions and the concern about employment opportunities are explored.

  1. Learning styles of first-year orthopedic surgical residents at 1 accredited institution. (United States)

    Caulley, Lisa; Wadey, Veronica; Freeman, Risa


    This study represents 1 arm of a 5-year prospective study investigating the learning styles of orthopedic residents and their surgical educators. This project investigates the learning styles of the 2009-2010 year 1 orthopedic surgical residents. A cross-sectional survey using the Kolb Learning Style Inventory was completed by 13 first year orthopedic residents. Direct 1-to-1 interviews were completed with the primary investigator and each participant using the Kolb Learning Style Inventory and learning styles were determined. Converging learning style was the most common among the residents (53.8%). Residents demonstrated a high tendency toward the learning skill of abstract conceptualization combined with active experimentation, and a transition from action-oriented to more reflective learning style with age and postgraduate education. These results may be useful in creating strategies specific to each learning style that will be offered to residents to enhance future teaching and learning.

    González Ojeda, A; Herrera Hernández, M F; Torres Mejía, G; Odor Morales, A; de la Garza Villaseñor, L


    The aim of this retrospective study was to evaluate the impact of resident participation in the results of surgical treatment in 1149 consecutive patients operated for biliary disease between January, 1980 and December, 1987 at the Instituto Nacional de la Nutrición "Salvador Zubirán". Patients were divided in three groups: GROUP I. 640 cases treated by surgical residents under a senior surgeon supervision. GROUP II. 168 patients operated by the chief surgical resident. GROUP III. 341 patients treated by senior staff surgeons. Age, sex and risk factors were similar between groups. Residents performed more operative cholangiograms (p less than 0.05). In general, senior surgeons performed more transduodenal sphincteroplasties (p less than 0.05) and other additional procedures like appendectomies and gastrostomies during the same surgery. Wound infection was more frequent in group III patients (p less than 0.005) but there was no significant clinical difference in other postoperative complications like intraabdominal abscess, bile fistula, wound dehiscence, intraabdominal bleeding, iatrogenic injury of the biliary tract, and residual common duct stone. The duration of the in-hospital convalescence period was similar in all three groups. The mortality rate for the total series was 2.2%. In group II there were more patients affected for acute cholecystitis, and more patients died postoperatively (p = less than 0.01). We may consider this difference attributable to the more complex patients handled by the chief resident. Mortality rate among patients with chronic biliary tract disease was less than 1%. We were not able to demonstrate any significant difference in mortality and complication rates between those patients operated by residents, chief residents and senior surgeons.(ABSTRACT TRUNCATED AT 250 WORDS)

  3. Generating patient-specific pulmonary vascular models for surgical planning (United States)

    Murff, Daniel; Co-Vu, Jennifer; O'Dell, Walter G.


    Each year in the U.S., 7.4 million surgical procedures involving the major vessels are performed. Many of our patients require multiple surgeries, and many of the procedures include "surgical exploration". Procedures of this kind come with a significant amount of risk, carrying up to a 17.4% predicted mortality rate. This is especially concerning for our target population of pediatric patients with congenital abnormalities of the heart and major pulmonary vessels. This paper offers a novel approach to surgical planning which includes studying virtual and physical models of pulmonary vasculature of an individual patient before operation obtained from conventional 3D X-ray computed tomography (CT) scans of the chest. These models would provide clinicians with a non-invasive, intricately detailed representation of patient anatomy, and could reduce the need for invasive planning procedures such as exploratory surgery. Researchers involved in the AirPROM project have already demonstrated the utility of virtual and physical models in treatment planning of the airways of the chest. Clinicians have acknowledged the potential benefit from such a technology. A method for creating patient-derived physical models is demonstrated on pulmonary vasculature extracted from a CT scan with contrast of an adult human. Using a modified version of the NIH ImageJ program, a series of image processing functions are used to extract and mathematically reconstruct the vasculature tree structures of interest. An auto-generated STL file is sent to a 3D printer to create a physical model of the major pulmonary vasculature generated from 3D CT scans of patients.

  5. How Should Surgical Residents Be Educated About Patient Safety: A Pilot Randomized Controlled Trial. (United States)

    Putnam, Luke R; Pham, Dean H; Ostovar-Kermani, Tiffany G; Alawadi, Zeinab M; Etchegaray, Jason M; Ottosen, Madelene J; Thomas, Eric J; Lesslie, Donald P; Kao, Lillian S; Lally, Kevin P; Tsao, KuoJen


    The Accreditation Council for Graduate Medical Education mandates patient safety education without specific curricular guidelines. We hypothesized that a dedicated, adjunctive resident safety workshop (SW) led by surgical faculty compared with an online curriculum (OC) for hospital personnel alone would improve residents' patient safety perceptions and behaviors. A pilot randomized controlled trial was performed from 2014 to 2015 within a university-based general surgery residency. Control and intervention groups, stratified by postgraduate year, participated in a hospital-based OC; the intervention group participated in an additional SW. Primary outcomes were perceptions of safety culture, teamwork, and speaking up as per the validated safety attitudes questionnaire (SAQ) at 6 and 12 months postintervention. Secondary outcomes included behavioral scores from blinded surgical faculty using the Oxford NonTechnical Skills scale. A total of 51 residents were enrolled (control = 25, intervention = 26). SAQ response rates were 100%, 100%, and 76% at baseline, 6 months, and 12 months, respectively. SAQ scores were similar at baseline between groups and did not change significantly at 6 or 12 months, independent of postgraduate year (PGY) level. Overall NonTechnical Skills scores were similar between groups, but senior residents (≥PGY 4) in the OC + SW group scored significantly higher in teamwork, decision-making, and situation awareness (all p < 0.05). An adjunctive, dedicated resident SW compared with a hospital-based OC alone did not significantly improve overall perceptions of patient safety. However, senior residents participating in the SW demonstrated improved patient safety perceptions and had significantly better intraoperative safety behaviors than senior residents in the OC group. Future curricular enhancements should include PGY-level specific education, iterative reviews, and increased faculty involvement. A larger randomized trial may be warranted

Method A survey of patient care - related communication skills among surgery residents and assessment of competence, rating the importance and perceived need for training in communication skills. Results Most residents rated their skills as either fairly or extremely competent in all areas except in providing bereavement counseling. They found all skills important and indicated a need for training in them. Senior registrars rated their competence and the importance higher in skills relating to breaking bad news, educating and preparing patients and families for surgery and encouraging them to express their anxieties.

Understanding the surgical trainees perceptions of patient care related communication skills is the first step in designing an effective education programme.

  7. Resistance to change in surgical residency: an ethnographic study of work hours reform. (United States)

    Kellogg, Katherine C; Breen, Elizabeth; Ferzoco, Stephen J; Zinner, Michael J; Ashley, Stanley W


    Although the practical challenges to work hour restrictions have been the focus of much discussion, cultural resistance to such change has received less attention. Surgical residency has its own unique social structure, and we hypothesized that challenges to this would provide impediments to successful implementation of duty hours reform. We used ethnographic research methods to study the efforts at work hour restriction over a 15-month period before the introduction of the Accreditation Council for Graduate Medical Education regulations. These methods, validated for studying institutional change, build on intense periods of observation. Records of observations are then analyzed and coded to uncover cultural and political challenges. The frequency of successful hand-offs in sign-out situations between day and night float residents was measured as an objective index of success. Practical issues were addressed initially by scheduling adjustments including creating a night float system. The hand-offs that this system required, however, were successful only 14% of the time. Subsequent steps to address the challenge to resident identity by top-down support of a new definition of professionalism increased the number of successful hand-offs to 39%. Finally, a reduction in a noted hierarchy violation led to successful hand-offs 79% of the time. These results demonstrate that practical solutions alone may not be a sufficient basis for change in surgical residency. While we face other challenges to the traditional surgical culture, attention to social and political issues may enhance the success of our efforts.

  8. Using Qualitative and Quantitative Assessment to Develop a Patient Safety Curriculum for Surgical Residents. (United States)

    McKee, Rohini; Sussman, Andrew L; Nelson, M Timothy; Russell, John C


    The objective is to use qualitative and quantitative analysis to develop a patient safety curriculum for surgical residents. A prospective study of surgical residents using both quantitative and qualitative methods to craft a patient safety curriculum. Both a survey and focus groups were held before and 4 months after delivery of the patient safety curriculum. The University of New Mexico Hospital, a tertiary academic medical center. General surgery residents, postgraduate years 1 to 5 RESULTS: Qualitative and quantitative analysis revealed areas that required attention and thus helped to mold the curriculum. Qualitative analysis after delivery of the curriculum showed positive changes in attitudes and normative beliefs toward patient safety. Specifically, attitudes and approach to quality improvement and teamwork showed improvement. Survey analysis did not show any significant change in resident perception of the environment during the time frame of this study. Using qualitative analysis to uncover attitudinal barriers to a safe patient environment can help to enhance the relevance and content of a patient safety curriculum for general surgery residents.

  9. Using optimization models to demonstrate the need for structural changes in training programs for surgical medical residents. (United States)

    Turner, Jonathan; Kim, Kibaek; Mehrotra, Sanjay; DaRosa, Debra A; Daskin, Mark S; Rodriguez, Heron E


    The primary goal of a residency program is to prepare trainees for unsupervised care. Duty hour restrictions imposed throughout the prior decade require that residents work significantly fewer hours. Moreover, various stakeholders (e.g. the hospital, mentors, other residents, educators, and patients) require them to prioritize very different activities, often conflicting with their learning goals. Surgical residents' learning goals include providing continuity throughout a patient's pre-, peri-, and post-operative care as well as achieving sufficient surgical experience levels in various procedure types and participating in various formal educational activities, among other things. To complicate matters, senior residents often compete with other residents for surgical experience. This paper features experiments using an optimization model and a real dataset. The experiments test the viability of achieving the above goals at a major academic center using existing models of delivering medical education and training to surgical residents. It develops a detailed multi-objective, two-stage stochastic optimization model with anticipatory capabilities solved over a rolling time horizon. A novel feature of the models is the incorporation of learning curve theory in the objection function. Using a deterministic version of the model, we identify bounds on the achievement of learning goals under existing training paradigms. The computational results highlight the structural problems in the current surgical resident educational system. These results further corroborate earlier findings and suggest an educational system redesign is necessary for surgical medical residents.

  10. Compassion Fatigue is Similar in Emergency Medicine Residents Compared to other Medical and Surgical Specialties (United States)

    Bellolio, M. Fernanda; Cabrera, Daniel; Sadosty, Annie T.; Hess, Erik P.; Campbell, Ronna L.; Lohse, Christine M.; Sunga, Karmen L.


    Introduction Compassion fatigue (CF) is the emotional and physical burden felt by those helping others in distress, leading to a reduced capacity and interest in being empathetic towards future suffering. Emergency care providers are at an increased risk of CF secondary to their first responder roles and exposure to traumatic events. We aimed to investigate the current state of compassion fatigue among emergency medicine (EM) resident physicians, including an assessment of contributing factors. Methods We distributed a validated electronic questionnaire consisting of the Professional Quality of Life Scale with subscales for the three components of CF (compassion satisfaction, burnout and secondary traumatic stress), with each category scored independently. We collected data pertaining to day- versus night-shift distribution, hourly workload and child dependents. We included residents in EM, neurology, orthopedics, family medicine, pediatrics, obstetrics, and general surgery. Results We surveyed 255 residents, with a response rate of 75%. Of the 188 resident respondents, 18% worked a majority of their clinical shifts overnight, and 32% had child dependents. Burnout scores for residents who worked greater than 80 hours per week, or primarily worked overnight shifts, were higher than residents who worked less than 80 hours (mean score 25.0 vs 21.5; p=0.013), or did not work overnight (mean score 23.5 vs 21.3; p=0.022). EM residents had similar scores in all three components of CF when compared to other specialties. Secondary traumatic stress scores for residents who worked greater than 80 hours were higher than residents who worked less than 80 hours (mean score 22.2 vs 19.5; p=0.048), and those with child dependents had higher secondary traumatic stress than those without children (mean score 21.0 vs 19.1; p=0.012).

    Full Text Available Abstract Background To analyse in a prospective trial the long-term results of Lichtenstein hernioplasty performed by surgical trainees. Methods Training of tension-free Lichtenstein hernia operation was started in our ambulatory unit as an outpatient procedure under local anaesthesia in 1996. After performing 36 teaching operations together with residents and their supervising specialist, 281 patients were operated during 1996-2000 either by one senior consultant (n = 141 or by 12 surgical trainees (n = 140. After 10 years, 247 (88% patients were available for the long-term assessment. Results After one month postoperatively, the rate of wound infections (consultant 1.1%, residents 0.7% and hematomas (consultant 1.1%, residents 3.0% were low and not related to surgeon's training level (ns. Only 6 (2.1% clinically evident recurrences were found after 10 years: two after specialist repair and four after trainee repair (ns. Although one third of the patients reported some discomfort after 3 and 10 years, 93-95% of the patients were very satisfied with the operation, with no statistical difference between the surgeons. Conclusion Ambulatory open mesh repair under local anaesthesia was a safe operation and the long-term results were acceptable among the patients operated by surgical trainees.

  13. Immersive virtual reality used as a platform for perioperative training for surgical residents. (United States)

    Witzke, D B; Hoskins, J D; Mastrangelo, M J; Witzke, W O; Chu, U B; Pande, S; Park, A E


    Perioperative preparations such as operating room setup, patient and equipment positioning, and operating port placement are essential to operative success in minimally invasive surgery. We developed an immersive virtual reality-based training system (REMIS) to provide residents (and other health professionals) with training and evaluation in these perioperative skills. Our program uses the qualities of immersive VR that are available today for inclusion in an ongoing training curriculum for surgical residents. The current application consists of a primary platform for patient positioning for a laparoscopic cholecystectomy. Having completed this module we can create many different simulated problems for other procedures. As a part of the simulation, we have devised a computer-driven real-time data collection system to help us in evaluating trainees and providing feedback during the simulation. The REMIS program trains and evaluates surgical residents and obviates the need to use expensive operating room and surgeon time. It also allows residents to train based on their schedule and does not put patients at increased risk. The method is standardized, allows for repetition if needed, evaluates individual performance, provides the possible complications of incorrect choices, provides training in 3-D environment, and has the capability of being used for various scenarios and professions.

    Shin, Jennifer J; Cunningham, Michael J; Emerick, Kevin G; Gray, Stacey T


    Surgical competency requires sound clinical judgment, a systematic diagnostic approach, and integration of a wide variety of nontechnical skills. This more complex aspect of clinician development has traditionally been difficult to measure through standard assessment methods. This study was conducted to use the Clinical Practice Instrument (CPI) to measure nontechnical diagnostic and management skills during otolaryngology residency training; to determine whether there is demonstrable change in these skills between residents who are in postgraduate years (PGYs) 2, 4, and 5; and to evaluate whether results vary according to subspecialty topic or method of administration. Prospective study using the CPI, an instrument with previously established internal consistency, reproducibility, interrater reliability, discriminant validity, and responsiveness to change, in an otolaryngology residency training program. The CPI was used to evaluate progression in residents' ability to evaluate, diagnose, and manage case-based clinical scenarios. A total of 248 evaluations were performed in 45 otolaryngology resident trainees at regular intervals. Analysis of variance with nesting and postestimation pairwise comparisons were used to evaluate total and domain scores according to training level, subspecialty topic, and method of administration. Longitudinal residency educational initiative. Assessment with the CPI during PGYs 2, 4, and 5 of residency. Among the 45 otolaryngology residents (248 CPI administrations), there were a mean (SD) of 5 (3) administrations (range, 1-4) during their training. Total scores were significantly different among PGY levels of training, with lower scores seen in the PGY-2 level (44 [16]) compared with the PGY-4 (64 [13]) or PGY-5 level (69 [13]) (P otolaryngology (mean [SD], 72 [14]) than in subspecialties (range, 55 [12], P = .003, to 56 [19], P < .001).

    Weir, Gregory


    Health care-associated infections in hospitals, including surgical site infections, contribute significantly to morbidity as well as mortality. Surgical incision management (SIM) using negative pressure wound therapy (Prevena™ Incision Management System, Kinetic Concepts, Inc., San Antonio, TX, USA) is designed to cover and protect closed surgical incisions from external factors including infectious sources and local trauma, while negative pressure removes fluid and infectious material from the surgical incision. A prospective case-control study assessed wound complications in patients undergoing vascular bypass procedures, where both femoral areas were incised to gain access to the femoral arteries. SIM was placed on one femoral area while a standard postoperative wound dressing was placed on the contralateral femoral area. Eight patients were included in this pilot study. All of them required bilateral femoral artery access. During the follow-up period patients were monitored for wound complications. All wound complications requiring surgical intervention were considered significant. No significant wound complications occurred in wounds treated with SIM, compared with three significant complications in control wounds. These preliminary data would suggest a potential reduction in wound complications and no observed increase in haemorrhage in high-risk patients with severe co-morbidities undergoing vascular surgery.

    Caldroney, S; Ghazali, N; Dyalram, D; Lubek, J E


    A retrospective review of all patients with stage 3 medication-related osteonecrosis of the jaw (MRONJ), treated by surgical resection and immediate vascularized bone reconstruction at a tertiary care medical center, was performed. Eleven patients were included, seven female and four male; their mean age was 65.8 years (range 56-73 years). Mean follow-up was 25 months. Ten patients had received intravenous bisphosphonates. The most common pathology was breast cancer (4/11). Pain (n=8) and pathological fracture (n=7) were the most common presenting symptoms. Microvascular free flaps consisted of seven fibula osteocutaneous flaps and four scapula osteocutaneous free flaps. All patients reported resolution of symptoms, with complete bone union identified radiographically (100%). Complications occurred in three patients (27%). One patient required removal of hardware at 8 months postoperative. Dental implant rehabilitation was completed in two patients. Ten patients are tolerating an oral diet. Ten patients are alive without evidence of MRONJ at any of the surgical sites. One patient died 28 months after surgery from progression of metastatic disease. Advanced MRONJ can be successfully treated in patients using vascularized tissue transfer, including those patients with significant peripheral vascular disease. Dental rehabilitation is a viable option for advanced MRONJ patients treated by vascularized flap reconstruction. Copyright © 2017 International Association of Oral and Maxillofacial Surgeons.

  18. A Comparison of Training Experience, Training Satisfaction, and Job Search Experiences between Integrated Vascular Surgery Residency and Traditional Vascular Surgery Fellowship Graduates. (United States)

    Colvard, Benjamin; Shames, Murray; Schanzer, Andres; Rectenwald, John; Chaer, Rabih; Lee, Jason T


    The first 2 integrated vascular residents in the United States graduated in 2012, and in 2013, 11 more entered the job market. The purpose of this study was to compare the job search experiences of the first cohort of integrated 0 + 5 graduates to their counterparts completing traditional 5 + 2 fellowship programs. An anonymous, Web-based, 15-question survey was sent to all 11 graduating integrated residents in 2013 and to the 25 corresponding 5 + 2 graduating fellows within the same institution. Questions focused on the following domains: training experience, job search timelines and outcomes, and overall satisfaction with each training paradigm. Survey response was nearly 81% for the 0 + 5 graduates and 64% for the 5 + 2 graduates. Overall, there was no significant difference between residents and fellows in the operative experience obtained as measured by the number of open and endovascular cases logged. Dedicated research time during the entire training period was similar between residents and fellows. Nearly all graduates were extremely satisfied with their training and had positive experiences during their job searches with respect to starting salaries, numbers of offers, and desired practice type. More 0 + 5 residents chose academic and mixed practices over private practices compared with 5 + 2 fellowship graduates. Although longer term data are needed to understand the impact of the addition of 0 + 5 graduating residents to the vascular surgery work force, preliminary survey results suggest that both training paradigms (0 + 5 and 5 + 2) provide positive training experiences that result in excellent job search experiences. Based on the current and future need for vascular surgeons in the work force, the continued growth and expansion of integrated 0 + 5 vascular surgery residency positions as an alternative to traditional fellowship training is thus far justified.

  19. The Colorado Humanitarian Surgical Skills Workshop: A Cadaver-Based Workshop to Prepare Residents for Surgery in Austere Settings. (United States)

    Lin, Yihan; Mukhopadhyay, Swagoto; Meguid, Robert A; Kuwayama, David P


    Interest in humanitarian surgery is high among surgical and obstetric residents. The Colorado Humanitarian Surgical Skills Workshop is an annual 2-day course exposing senior residents to surgical techniques essential in low- and middle-income countries but not traditionally taught in US residencies. We evaluated the course's ability to foster resident comfort, knowledge, and competence in these skills. The cohort of course participants was studied prospectively. Participants attended didactic sessions followed by skills sessions using cadavers. Sample areas of focus included general surgery (mesh-free hernia repair), orthopedics (powerless external fixation), and neurosurgery (powerless craniotomy). Before and after the course, participants answered a questionnaire assessing confidence with taught skills; took a knowledge-based test composed of multiple choice and open-ended questions; and participated in a manual skills test of tibial external fixation. The Center for Surgical Innovation, University of Colorado School of Medicine. A total of 12 residents (11 general surgical and 1 obstetric) from ten US institutions. After the course, participants perceived increased confidence in performing all 27 taught procedures and ability to practice in low- and middle-income countries. In knowledge-based testing, 10 of 12 residents demonstrated improvement on multiple choice questioning and 9 of 12 residents demonstrated improvement on open-ended questioning with structured scoring. In manual skills testing, all external fixator constructs demonstrated objective improvement on structured scoring and subjective improvement on stability assessment. For senior residents interested in humanitarian surgery, a combination of skills-focused teaching and manual practice led to self-perceived and objective improvement in relevant surgical knowledge and skills. The Colorado Humanitarian Surgical Skills Workshop represents an effective model for transmitting essential surgical

    Falcone, John L


    The Arnold P. Gold Humanism and Excellence in Teaching Awards are given by medical students to residents. The aim of this study is to evaluate the distribution of this award based on residency specialty. The hypothesis is that surgical residents more commonly receive this award. This was a retrospective study from 2004 to 2013. All award recipients were obtained from the Arnold P. Gold Foundation website. The specialties of award recipients were tabulated. The number of award winners per thousand specialty residents was estimated using the Accreditation Council for Graduate Medical Education Data Resource Book, adjusting for the number of awarding schools and resident specialties. All statistics used an α = 0.05. There were 2489 awards given during the study period, with 52.6% in medical specialties and 47.4% in surgical specialties (p = 0.45). The specialties most commonly awarded were General Surgery (22.3%), Internal Medicine (20.9%), and Obstetrics/Gynecology (20.4%). Adjusting for the number of eligible residents, there were 59.9 awards/1000 Obstetrics/Gynecology residents, 43.1 awards/1000 General Surgery residents, and 20.2 awards/1000 Internal Medicine residents (p Humanism and Excellence in Teaching Awards are more commonly given to surgical specialty residents.

  2. The vascular anatomy of the human temporalis muscle: implications for surgical splitting techniques. (United States)

    Cheung, L K


    Despite the wide application of the temporalis muscle flap and its modifications, understanding of the vascular pattern and territories within the muscle remains poor. This study aimed to evaluate the vascular architecture in the human temporalis muscle for surgical application. The material comprised 15 fresh cadavers (30 muscle specimens), which were divided into three groups for vascular infusion by either Indian ink solution, lead oxide solution, or methylmethacrylate resin. The vascular network in the temporalis muscle was analyzed by stereomicroscopy, radiography, and scanning electron microscopy. The human temporalis muscle was found to have vascular supply from three primary arteries: the anterior deep temporal artery (ADTA), the posterior deep temporal artery (PDTA), and the middle temporal artery (MTA). Each primary artery branched into the secondary arterioles and then the terminal arterioles. The venous network accompanied the arteries, and double veins pairing one artery was a common finding. The capillaries formed a dense, interlacing network with orientation along the muscle fibres. Arteriovenous anastomosis was absent. In the coronal plane, the vessels were located mainly on the lateral and medial aspects of the muscle with a significantly lower vascular density in the midline. Morphometric analysis of the arterial network showed that the PDTA was larger in size at primary and secondary branching levels than the ADTA and the MTA, whereas no differences were present at the terminal arteriolar levels. The distribution of the arterial territories was as follows: the ADTA occupied 21% anteriorly, the PDTA occupied 41% in the middle region, and the MTA occupied 38% in the posterior region. This improved understanding of the vascular architecture within the temporalis muscle complements the anatomic basis of the flap-splitting technique and increases the safety of its application.

  3. Vascular anatomy of the patella: implications for total knee arthroplasty surgical approaches. (United States)

    Lazaro, Lionel E; Cross, Michael B; Lorich, Dean G


    Iatrogenic disruption of the patellar vascular supply has been identified as a possible contributing factor to the commonly reported patellofemoral complications following total knee arthroplasty (TKA). We performed an anatomic cadaveric study evaluating the extra-osseous vascular anatomy of the patella, and correlated our findings to routine TKA surgical dissection to determine how to better preserve patellar vascularity. In twenty-one cadaveric knees arterial cannulas were placed proximally and distally to the patella. A polyurethane compound was then injected producing a visible arterial network. Specimens underwent gross dissection. In all 21 specimens, the supreme genicular (SGA), medial/lateral superior genicular (MSGA/LSGA), medial/lateral inferior genicular and anterior tibial recurrent arteries communicate forming a peripatellar anastomotic ring supplying the intraosseous patellar system. Both the SGA (24%) and MSGA (76%) demonstrated dual medial ring contribution. Relating the arterial location to common TKA exposures suggested severe compromise of patellar vascularity. The medial sided vessels seem to contribute more significantly to the peripatellar anastomotic ring when compared to the lateral sided vessels. Careful soft tissue management has the potential to preserve key vascular structures that could maintain the intraosseous vascular supply to the patella. Understanding the anatomic locations of major arterial systems around the knee joint can potentially help during hemostasis, and can minimize blood loss during TKA. Recognition of major arterial systems around the knee joint has the potential to minimize iatrogenic disruption of the vascular supply and the complications that can follow (patella devascularization and blood lost).

  4. The effect of the 16-hour intern workday restriction on surgical residents' in-hospital activities. (United States)

    Dennis, Bradley M; Long, Eric L; Zamperini, Katherine M; Nakayama, Don K


    To observe the effects of the 2011 Accreditation Council on Graduate Medical Education 16-hour intern workday restrictions on surgical residents' clinical and educational activities. All the residents recorded the following weekly in-hospital activities during February and March 2011 (year before intern work restrictions) and 2012 (first year under new requirements): operating room (OR) and clinic; bedside procedures; rounds and ward work; on-call duties in hospital; communication (e.g., checkouts and family and patient discussions); education (conferences and study); and personal (rest and meals). Descriptive statistics were calculated in 3 resident groups (interns, first postgraduate year [PGY1]; junior, PGY2 and 3; and senior, PGY4 and 5). The unpaired t test was used to compare data between 2011 and 2012; significance was set at pintern did not change (all results in h/wk, mean±standard deviation: 68.5±13.8 to 72.8±15.8, respectively) but the time devoted to specific activities changed significantly. In-hospital personal time decreased by 50% (5.3±4.6 to 2.6±2.0, p = 0.004). Interns spent less time placing central lines (2.1±2.2 to 0.9±1.2, p = 0.006) and more on rounds (8.8±8.8 to 14.2±9.8, p = 0.027), which included supervision with upper level residents. There was no change in the total time spent in the OR, the clinic, performing bedside procedures, and educational activities. Changes in intern work did not affect the time junior and senior residents spent on bedside procedures, time spent in the clinic, and total time spent in the hospital. In 2012, junior residents spent less time in educational activities (11.4±8.5 to 7.0±4.5, p = 0.0007) and the seniors spent more time in the OR (13.7±7.5 to 20.6±10.7, p = 0.0002). The 16-hour restriction preserved interns' educational activities and time spent in the OR and clinic, but changed resident work activities at all levels. The time spent on rounds increased, time spent by the juniors on

    Bhandari, Mohit; Montori, Victor; Devereaux, P J; Dosanjh, Sonia; Sprague, Sheila; Guyatt, Gordon H


    To examine surgical trainees' barriers to implementing and adopting evidence-based medicine (EBM) in the day-to-day care of surgical patients. In 2000, 28 surgical residents from various subspecialties at a hospital affiliated with McMaster University Faculty of Health Sciences in Ontario, Canada, participated in a focus group (n = 8) and semistructured interviews (n = 20) to explore their perceptions of barriers to the practice of EBM during their training. Additional themes were explored, such as definitions of EBM and potential strategies to implement EBM during training. The canons and procedures of the grounded theory approach to qualitative research guided the coding and content analysis of the data derived from the focus group and semistructured interviews. Residents identified personal barriers, staff-surgeon barriers, and institutional barriers that limited their ability to apply EBM in their daily activities. Residents perceived their lack of education in EBM, time constraints, lack of priority, and fear of staff disapproval as major challenges to practicing EBM. Moreover, the lack of ready access to surgical EBM resource materials proved to be an important additional factor limiting EBM surgical practice. Residents identified several strategies to overcome these barriers to EBM, including hiring staff surgeons with EBM training, offering coursework in critical appraisal for all staff, improving interdepartmental communication, and providing greater flexibility for EBM training. Surgical residents identified a general lack of education, time constraints, lack of priority, and staff disapproval as important factors limiting incorporation of EBM. Curriculum reform and surgeon education may help overcome these barriers.

  6. [Surgical treatment of mature extracephalic vascular malformations (excluding portwine hemangioma). Experience of this department]. (United States)

    Martin, D; Legaillard, P; Baudet, J


    The department's experience of mature extracephalic vascular malformations shows that, regardless of the site and the type of the lesion, only surgical excision is able to ensure a good result for vascular malformations of the limbs. The results were almost always excellent and only the diffuse forms benefitted from preoperative sclerosant injections. Palliative treatments such as elastic compression still have a place in these indications. Arterial embolisations are only of limited value, particularly when they are selective, as a complement to surgery (risk of necrosis in peripheral lesions). All sites may be observed, but the authors particularly emphasise perineoscrotal lymphangiomatous lesions. Recurrences do occur, but are rare when the lesion is widely resected and a good quality reconstruction is performed.

  7. Collagen implant with gentamicin sulphate reduces surgical site infection in vascular surgery: a prospective cohort study. (United States)

    Costa Almeida, Carlos Eduardo Perdigão; Reis, Luis; Carvalho, Luis; Costa Almeida, Carlos Manuel


    Surgical site infection (SSI) is a common complication after vascular surgery. It may cause exposure of the underlying prosthesis causing graft infection, which may require the removal of the vascular graft, increasing amputation and mortality risks. Graft contamination usually occurs during operative procedure or by direct spread from an infected wound. It is therefore advisable to a strong effort in reducing SSI. Topic antibiotics have not been fully studied in vascular surgery, but collagen implant with gentamicin sulphate has shown to reduce SSI in cardiac surgery, orthopaedics, and general surgery procedures. Sixty (60) non-diabetic and non-obese patients with lower limb ischaemia with indication for femoropopliteal PTFE prosthetic bypass were allocated into 2 groups of 30 patients. A collagen implant impregnated with gentamicin sulphate (Collatamp(®)) was applied in the groin incision adjacent to the prosthesis in one group, and the other was a control group. The same surgical team operated all patients. Szilagyi classification was used. There was no SSI (0% - 0/30) in the collagen implant with gentamicin sulphate group, contrasting with 6 cases (20% - 6/30) of SSI (grade I and II) in the control group (p = 0.024). In-hospital day's data shows a significant difference between the two groups (p = 0.004) with a mean of 5.66 days for implant group and 8.10 days for control group. There was no SSI grade III. Collagen implant with gentamicin sulphate (Collatamp(®)) reduces SSI in the groin incision in ischaemic patients submitted to femoropopliteal PTFE prosthetic bypass. Days of hospitalization are also reduced. Decreasing SSI rate and in-hospital days, this implant may also reduce health care costs. Because this is a small pilot study, a multicentre RCT is necessary for validation. Copyright © 2014 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

  9. Guidelines for resident training in veterinary clinical pathology. III: cytopathology and surgical pathology. (United States)

    Kidney, Beverly A; Dial, Sharon M; Christopher, Mary M


    The Education Committee of the American Society for Veterinary Clinical Pathology has identified a need for improved structure and guidance of training residents in clinical pathology. This article is the third in a series of articles that address this need. The goals of this article are to describe learning objectives and competencies in knowledge, abilities, and skills in cytopathology and surgical pathology (CSP); provide options and ideas for training activities; and identify resources in veterinary CSP for faculty, training program coordinators, and residents. Guidelines were developed in consultation with Education Committee members and peer experts and with evaluation of the literature. The primary objectives of training in CSP are: (1) to develop a thorough, extensive, and relevant knowledge base of biomedical and clinical sciences applicable to the practice of CSP in domestic animals, laboratory animals, and other nondomestic animal species; (2) to be able to reason, think critically, investigate, use scientific evidence, and communicate effectively when making diagnoses and consulting and to improve and advance the practice of pathology; and (3) to acquire selected technical skills used in CSP and pathology laboratory management. These guidelines define expected competencies that will help ensure proficiency, leadership, and the advancement of knowledge in veterinary CSP and will provide a useful framework for didactic and clinical activities in resident-training programs.

  10. Training Surgical Residents With a Haptic Robotic Central Venous Catheterization Simulator. (United States)

    Pepley, David F; Gordon, Adam B; Yovanoff, Mary A; Mirkin, Katelin A; Miller, Scarlett R; Han, David C; Moore, Jason Z


    Ultrasound guided central venous catheterization (CVC) is a common surgical procedure with complication rates ranging from 5 to 21 percent. Training is typically performed using manikins that do not simulate anatomical variations such as obesity and abnormal vessel positioning. The goal of this study was to develop and validate the effectiveness of a new virtual reality and force haptic based simulation platform for CVC of the right internal jugular vein. A CVC simulation platform was developed using a haptic robotic arm, 3D position tracker, and computer visualization. The haptic robotic arm simulated needle insertion force that was based on cadaver experiments. The 3D position tracker was used as a mock ultrasound device with realistic visualization on a computer screen. Upon completion of a practice simulation, performance feedback is given to the user through a graphical user interface including scoring factors based on good CVC practice. The effectiveness of the system was evaluated by training 13 first year surgical residents using the virtual reality haptic based training system over a 3 month period. The participants' performance increased from 52% to 96% on the baseline training scenario, approaching the average score of an expert surgeon: 98%. This also resulted in improvement in positive CVC practices including a 61% decrease between final needle tip position and vein center, a decrease in mean insertion attempts from 1.92 to 1.23, and a 12% increase in time spent aspirating the syringe throughout the procedure. A virtual reality haptic robotic simulator for CVC was successfully developed. Surgical residents training on the simulation improved to near expert levels after three robotic training sessions. This suggests that this system could act as an effective training device for CVC. Copyright © 2017 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

  11. Use of Google Glass to Enhance Surgical Education of Neurosurgery Residents: "Proof-of-Concept" Study. (United States)

    Nakhla, Jonathan; Kobets, Andrew; De la Garza Ramos, Rafeal; Haranhalli, Neil; Gelfand, Yaroslav; Ammar, Adam; Echt, Murray; Scoco, Aleka; Kinon, Merritt; Yassari, Reza


    The relatively decreased time spent in the operating room and overall reduction in cases performed by neurosurgical trainees as a result of duty-hour restrictions demands that the pedagogical content within each surgical encounter be maximized and crafted toward the specific talents and shortcomings of the individual. It is imperative to future generations that the quality of training adapts to the changing administrative infrastructures and compensates for anything that may compromise the technical abilities of trainees. Neurosurgeons in teaching hospitals continue to experiment with various emerging technologies-such as simulators and virtual presence-to supplement and improve surgical training. The authors participated in the Google Glass Explorer Program in order to assess the applicability of Google Glass as a tool to enhance the operative education of neurosurgical residents. Google Glass is a type of wearable technology in the form of eyeglasses that employs a high-definition camera and allows the user to interact using voice commands. Google Glass was able to effectively capture video segments of various lengths for residents to review in a variety of clinical settings within a large, tertiary care university hospital, as well as during a surgical mission to a developing country. The resolution and quality of the video were adequate to review and use as a teaching tool. While Google Glass harbors the potential to dramatically improve both neurosurgical education and practice in a variety of ways, certain technical drawbacks of the current model limit its effectiveness as a teaching tool.

  12. A systematic review and meta-analysis of factors for delirium in vascular surgical patients. (United States)

    Oldroyd, Christopher; Scholz, Anna F M; Hinchliffe, Robert J; McCarthy, Kathryn; Hewitt, Jonathan; Quinn, Terrence J


    Delirium is a common syndrome responsible for a large burden of morbidity and mortality. In surgical settings, research into risk factors for postoperative delirium has largely focused on elective orthopedic patients. We performed a systematic review and meta-analysis to evaluate the evidence surrounding risk factors for delirium in vascular surgical populations. Two independent reviewers searched five databases (MEDLINE, Web of Science, Embase, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO) from January 1987 to December 2015. We included primary research studies for incident delirium that used validated delirium assessment tools in exclusively vascular surgical populations. We identified 16 studies (3817 patients) that met the inclusion criteria. There was substantial clinical heterogeneity in the populations included under a heading of "vascular surgery." Studies were high quality, with an average Newcastle-Ottawa Scale score of 6.9. Summary incidence of delirium was 23.4% (range, 4.8%-39%). Across all studies, 157 separate risk factors were examined. Ten of the included studies used multivariable models in their analysis of risk factors. Meta-analysis of risk factors with data from more than three studies identified the following factors as conferring an increased risk of delirium: American Society of Anesthesiologists score >2 (odds ratio [OR], 3.44), renal failure (OR, 2.09), previous stroke (OR, 1.87), history of neurologic comorbidity (OR, 1.57), and male sex (OR, 1.30). Delirious patients were older (mean difference [MD], +4.99 years), had lower preoperative hemoglobin levels (MD, -0.66 g/dL), and stayed longer in intensive care units (MD, +1.06 days). Delirium is common in vascular surgery settings. Meta-analysis has identified significant risk factors relating to the patient, the presentation, and the pathway of care. Better understanding of these risk factors may help in prediction, prevention, and early identification of

  13. Surgical choroidal neovascular membrane removal in the era of anti-vascular endothelial growth factor agents

    Directory of Open Access Journals (Sweden)

    Nagpal Manish


    Full Text Available Intravitreal anti-vascular endothelial growth factor (VEGF agents have obtained acceptance as the mainstay in the management strategy of subfoveal choroidal neovascular membranes (CNVM due to varying etiologies. Few drawbacks include need for repeated intravitreal injections, with its adjunct risks, and the lack of a predefined treatment end point, which can cause doubts and uncertainty in the mind of the patient. Furthermore, it remains a significant financial burden for the patient. Herein we report our data of three patients who were reluctant for further re-injections of anti-VEGF agents and were therefore offered surgical removal of the CNVM by submacular surgery as an alternative treatment plan.

  14. A statewide consortium of surgical care: a longitudinal investigation of vascular operative procedures at 16 hospitals. (United States)

    Henke, Peter K; Kubus, Jim; Englesbe, Michael J; Harbaugh, Calista; Campbell, Darrell A


    Regional surgical quality improvement consortiums are becoming more common. Herein we have reported the effectiveness of a statewide consortium focusing on open vascular operative procedures. The statewide Michigan Surgical Quality Consortium was established in 2005 with 16 hospitals that report cases of vascular open operative intervention, in a sampling manner consistent with the private sector National Surgical Quality Improvement Program. Data are abstracted by onsite trained nurses using defined and validated pre-, peri-, and postoperative variables with 30-day follow-up. Outpatient and emergent cases were excluded. We compared outcomes over the course of the consortium (era I, April 2005-March 2007; era II, April 2007-March 2008) via univariate and multivariate techniques. Era I (n = 2,453) and era II (n = 3,409) cases were similar in age (mean, 68 years), gender (61% male), relative value units (mean, 21), and distribution of Current Procedural Terminology codes. Duration of stay and operative time decreased by 15% and 11%, respectively, when comparing era I with era II (P cardiac or renal, complications. When evaluating both eras, modifiable variables (able to be altered by the surgeon) for morbidity included increased length of operation (odds ratio [OR], 1.004; 95% confidence interval [CI], 1.003-1.005; P < .0001), hypertension (OR, 1.46; 95% CI, 1.03-2.1; P = .03), and blood transfusion (OR, 2.8; 95% CI, 2.04-3.88; P < .0001). However, anemic patients (11%; hematocrit <30) who were transfused were less likely to suffer morbidity (OR, 56; 95% CI, 0.47-0.67; P < .0001) than those transfused who were not anemic. The absolute 2% reduction in complications led to a $172 cost savings for the payers per patient in era II compared with era I. A statewide quality-of-care consortium with timely feedback of data was associated with decreased morbidity over a relatively short follow-up period in vascular patients. Focusing on best processes in real-world practice

    Partial or complete necrosis of skin flaps remains a significant problem in plastic and reconstructive surgery. Growth factors have shown promise in improving flap survival through increased angiogenesis and blood supply to the flap. Vascular endothelial growth factor (VEGF) is the most widely investigated and successful one. But the mechanisms of the effects are still not very clear. In the course of a series of experiments, we indicated that tissue survival of surgical flaps could be improved by both preoperative (sustained phase effect) and intraoperative (acute phase effect) application of VEGF. We reviewed both experimental and clinical investigations on the use of VEGF with surgical flaps to summarize the evidence of both phases of VEGF activity in promotion of flaps survival in detail. With the combinations of acute and sustained phases of effects, VEGF protein and gene, VEGF morphologic actions, and VEGF histochemical modulations suggest a pattern of VEGF activity that can be superimposed on classic descriptive mechanisms of tissue survival of flaps.

    Full Text Available BACKGROUND: Surgical site infections (SSI's are associated with severe morbidity, mortality and increased health care costs in vascular surgery. OBJECTIVE: To implement a bundle of care in vascular surgery and measure the effects on the overall and deep-SSI's rates. DESIGN: Prospective, quasi-experimental, cohort study. METHODS: A prospective surveillance for SSI's after vascular surgery was performed in the Amphia hospital in Breda, from 2009 through 2011. A bundle developed by the Dutch hospital patient safety program (DHPSP was introduced in 2009. The elements of the bundle were (1 perioperative normothermia, (2 hair removal before surgery, (3 the use of perioperative antibiotic prophylaxis and (4 discipline in the operating room. Bundle compliance was measured every 3 months in a random sample of surgical procedures and this was used for feedback. RESULTS: Bundle compliance improved significantly from an average of 10% in 2009 to 60% in 2011. In total, 720 vascular procedures were performed during the study period and 75 (10.4% SSI were observed. Deep SSI occurred in 25 (3.5% patients. Patients with SSI's (28,5±29.3 vs 10.8±11.3, p<0.001 and deep-SSI's (48.3±39.4 vs 11.4±11.8, p<0.001 had a significantly longer length of hospital stay after surgery than patients without an infection. A significantly higher mortality was observed in patients who developed a deep SSI (Adjusted OR: 2.96, 95% confidence interval 1.32-6.63. Multivariate analysis showed a significant and independent decrease of the SSI-rate over time that paralleled the introduction of the bundle. The SSI-rate was 51% lower in 2011 compared to 2009. CONCLUSION: The implementation of the bundle was associated with improved compliance over time and a 51% reduction of the SSI-rate in vascular procedures. The bundle did not require expensive or potentially harmful interventions and is therefore an important tool to improve patient safety and reduce SSI's in patients undergoing

  17. An evaluation of the success of a surgical resident learning portfolio. (United States)

    Webb, Travis P; Merkley, Taylor R


    Learning portfolios have gained modest acceptance in graduate medical education because of challenges related to user satisfaction, time and resource commitment, and quality assessment. In 2001, the Department of Surgery implemented the Surgical Learning and Instructional Portfolio (SLIP) to help residents develop a case-based portfolio demonstrating practice-based learning. In 2008, the format was changed to a Web-based platform with open viewing of portfolios for all learners. This study was performed to evaluate the SLIP program using resident and faculty perspectives in the domains of satisfaction, compliance, and educational value. Likert scale surveys were distributed to residents to assess satisfaction. Using a semistructured format with subsequent qualitative analysis of the meeting transcript, a focus group discussion was held with the SLIP director, SLIP facilitator, and program coordinator. An analysis of the program compliance was performed by review of SLIP entry dates. Finally, the quality of the SLIP entries (n = 420) was analyzed in a blinded manner using a locally developed standardized SLIP assessment tool. Data analysis was performed using Pearson's correlation and Cronbach's alpha. Residents were satisfied with the program and felt the Web-based format promoted self-reflection. They perceived that time spent was appropriate. Residents also believed they gained medical knowledge of their own specific entry topics but did not learn routinely from others' entries. Faculty asserted that the Web-based platform eased the administrative burden but did not necessarily alter the quality of the SLIP entries. Compliance with the assignment was 100%. SLIP entry analysis demonstrated the reflection and understanding of the topics chosen. However, the overall quality assessment of entries was hindered by suboptimal interrater reliability (inter-rater reliability (IR) = 0.636). The SLIP program allows residents to demonstrate practice-based learning and

    OBJECTIVE Majewski osteodysplastic primordial dwarfism Type II (MOPD II) is a rare genetic disorder. Features of it include extremely small stature, severe microcephaly, and normal or near-normal intelligence. Previous studies have found that more than 50% of patients with MOPD II have intracranial vascular anomalies, but few successful surgical revascularization or aneurysm-clipping cases have been reported because of the diminutive arteries and narrow surgical corridors in these patients. Here, the authors report on a large series of patients with MOPD II who underwent surgery for an intracranial vascular anomaly. METHODS In conjunction with an approved prospective registry of patients with MOPD II, a prospectively collected institutional surgical database of children with MOPD II and intracranial vascular anomalies who underwent surgery was analyzed retrospectively to establish long-term outcomes. RESULTS Ten patients with MOPD II underwent surgery between 2005 and 2012; 5 patients had moyamoya disease (MMD), 2 had intracranial aneurysms, and 3 had both MMD and aneurysms. Patients presented with transient ischemic attack (TIA) (n = 2), ischemic stroke (n = 2), intraparenchymal hemorrhage from MMD (n = 1), and aneurysmal subarachnoid hemorrhage (n = 1), and 4 were diagnosed on screening. The mean age of the 8 patients with MMD, all of whom underwent extracranial-intracranial revascularization (14 indirect, 1 direct) was 9 years (range 1-17 years). The mean age of the 5 patients with aneurysms was 15.5 years (range 9-18 years). Two patients experienced postoperative complications (1 transient weakness after clipping, 1 femoral thrombosis that required surgical repair). During a mean follow-up of 5.9 years (range 3-10 years), 3 patients died (1 of subarachnoid hemorrhage, 1 of myocardial infarct, and 1 of respiratory failure), and 1 patient had continued TIAs. All of the surviving patients recovered to their neurological baseline. CONCLUSIONS Patients with MMD

  20. Can a teaching assistant experience in a surgical anatomy course influence the learning curve for nontechnical skill development for surgical residents? (United States)

    Heidenreich, Mark J; Musonza, Tashinga; Pawlina, Wojciech; Lachman, Nirusha


    The foundation upon which surgical residents are trained to work comprises more than just critical cognitive, clinical, and technical skill. In an environment where the synchronous application of expertise is vital to patient outcomes, the expectation for optimal functioning within a multidisciplinary team is extremely high. Studies have shown that for most residents, one of the most difficult milestones in the path to achieving professional expertise in a surgical career is overcoming the learning curve. This view point commentary provides a reflection from the two senior medical students who have participated in the Student-as-Teacher program developed by the Department of Anatomy at Mayo Clinic, designed to prepare students for their teaching assistant (TA) role in anatomy courses. Both students participated as TAs in a six week surgical anatomy course for surgical first assistant students offered by the School of Health Sciences at Mayo Clinic. Development of teaching skills, nontechnical leadership, communication, and assessment skills, are discussed in relation to their benefits in preparing senior medical students for surgical residency.

  1. Coaching Non-technical Skills Improves Surgical Residents' Performance in a Simulated Operating Room. (United States)

    Yule, Steven; Parker, Sarah Henrickson; Wilkinson, Jill; McKinley, Aileen; MacDonald, Jamie; Neill, Adrian; McAdam, Tim


    To investigate the effect of coaching on non-technical skills and performance during laparoscopic cholecystectomy in a simulated operating room (OR). Non-technical skills (situation awareness, decision making, teamwork, and leadership) underpin technical ability and are critical to the success of operations and the safety of patients in the OR. The rate of developing assessment tools in this area has outpaced development of workable interventions to improve non-technical skills in surgical training and beyond. A randomized trial was conducted with senior surgical residents (n = 16). Participants were randomized to receive either non-technical skills coaching (intervention) or to self-reflect (control) after each of 5 simulated operations. Coaching was based on the Non-Technical Skills For Surgeons (NOTSS) behavior observation system. Surgeon-coaches trained in this method coached participants in the intervention group for 10 minutes after each simulation. Primary outcome measure was non-technical skills, assessed from video by a surgeon using the NOTSS system. Secondary outcomes were time to call for help during bleeding, operative time, and path length of laparoscopic instruments. Non-technical skills improved in the intervention group from scenario 1 to scenario 5 compared with those in the control group (p = 0.04). The intervention group was faster to call for help when faced with unstoppable bleeding in the final scenario (no. 5; p = 0.03). Coaching improved residents' non-technical skills in the simulated OR compared with those in the control group. Important next steps are to implement non-technical skills coaching in the real OR and assess effect on clinically important process measures and patient outcomes.

    To evaluate orthopedic resident perceptions of a didactic curriculum presented in traditional and case-based formats. Prospective cohort study using anonymous web-based survey after each conference evaluating resident perceptions of faculty participation, didactic delivery, content, and overall conference value. Conferences were structured as primarily case-based or traditional lecture. Logistic analysis was performed to determine factors predictive of rating a conference as valuable time spent. Orthopedic residency training program at single institution over an academic year. Orthopedic residents in postgraduate training year 1 to 5 attending mandatory didactic conference. Cased-based conferences received higher Likert ratings on residents' perception of faculty participation, instructor delivery, and improvement in topic understanding when compared to traditional lecture-based conferences (p didactic sessions. Junior levels residents are not perceived as effective as senior residents and faculty in presenting material in either format. These methods allow for a dynamic approach to identifying strengths and weaknesses in a resident curriculum as a well as a means for more focused and real-time improvements.

  4. Dedicated Research Time During Surgery Residency Leads to a Significant Decline In Self-Assessed Clinical Aptitude and Surgical Skills. (United States)

    Grova, Monica M; Yang, Anthony D; Humphries, Misty D; Galante, Joseph M; Salcedo, Edgardo S


    The surgical community commonly perceives a decline in surgical and patient care skills among residents who take dedicated time away from clinical activity to engage in research. We hypothesize that residents perceive a decline in their skills because of dedicated research time. UC Davis Medical Center, Sacramento, CA, an institutional tertiary care center. General surgery residents and graduates from UC Davis general surgery residency training program, who had completed at least 1 year of research during their training. A total of 35 people were asked to complete the survey, and 19 people submitted a completed survey. Participants were invited to complete an online survey. Factors associated with the decline in skills following their research years were examined. All statistical analyses were performed with IBM SPSS Statistics software. A total of 19 current or former general surgery residents responded to the survey (54% response rate). Overall, 42% described their research as "basic science." Thirteen residents (68%) dedicated 1 year to research, while the remainder spent 2 or more years. Basic science researchers were significantly more likely to report a decrease in clinical judgment (75% vs. 22%, p = 0.013) as well as a decrease in patient care skills (63% vs. 0%, p = 0.002). Residents who dedicated at least 2 years to research were more likely to perceive a decline in overall aptitude and surgical skills (100% vs. 46%, p = 0.02), and a decline in patient care skills (67% vs. 8%, p = 0.007). Most residents who dedicate time for research perceive a decline in their overall clinical aptitude and surgical skills. This can have a dramatic effect on the confidence of these residents in caring for patients and leading a care team once they re-enter clinical training. Residents who engaged in 2 or more years of research were significantly more likely to perceive these problems. Further research should determine how to keep residents who are interested in academics

  5. Don't all veins look alike? Comprehensively attending to diversity within the vascular surgical specialty. (United States)

    Hancock, Ange-Marie; Hancock, Charles R


    Prior research has established diversity as a topic of empirical analysis in the vascular surgery literature. Building on the work of previously published articles on diversity in the Journal of Vascular Surgery and elsewhere, this article engages in a broad discussion of diversity in two interrelated arenas: educational/workplace diversity and culturally competent care. Interdisciplinary review of the literature indicates that diversity is often thought of as an end-state to be accomplished. A more fruitful way to encompass the changing aspects of diversity work is to think of diversity as a set of processes that can be adjusted based on a set of interrelated goals that matter differently to different groups. In considering diversity as a process, an approach to diversity emerges that considers both independent effects of gender and race/ethnicity as well as interactive effects between the two variables to address future trends in medical education. Such trends are diagnosed and multiple courses of intervention are offered as reasonable options for future efforts. A comprehensive definition of diversity will be established in order to encompass two different arenas in which diversity concerns arise: educational diversity and culturally competent patient care. Second, a discussion of the rationales for attention to diversity among vascular surgeons will provide different avenues into a conversation about diversity in the profession. In so doing, three successful efforts will be briefly discussed: the Ohio State University's MED-Path program, the Keck School of Medicine's chair-centered approach to diversity in residency training, and the American Association of Orthopedic Surgeons' (AAOS) approach to culturally competent care.

  6. Surgical treatment of an exposed orbital implant with vascularized superficial temporal fascia flap. (United States)

    Basterzi, Yavuz; Sari, Ayca; Sari, Alper


    Orbital implants are often used for the correction of volume deficit after enucleation or evisceration. An orbital implant enhances aesthetics and improves mobility of the subsequent prosthetic eye. With advancements in technology and techniques, implant-related complication rates have been decreased. However, implant exposition as one of the most common complications of socket surgery is still a problem for the oculoplastic surgeon. Many factors are thought to cause orbital implant exposure: Large implants, tension on the wound, and textured surface of the implant may cause a breakdown of the covering layers over the implant. Inadequate fibrovascular ingrowth into the porous implant is the most important factor. Various surgical methods have been described to cover the defect, most offering the use of various tissues as a graft, which are not always satisfactory. We describe a case with silicone implant exposition that was managed with a vascularized superficial temporal fascia flap. According to our knowledge, this is the first article reporting the usage of a vascular tissue in the management of an orbital implant exposure.

  7. Applied Research on Laparoscopic Simulator in the Resident Surgical Laparoscopic Operation Technical Training. (United States)

    Fu, Shangxi; Liu, Xiao; Zhou, Li; Zhou, Meisheng; Wang, Liming


    The purpose of this study was to estimate the effects of surgical laparoscopic operation course on laparoscopic operation skills after the simulated training for medical students with relatively objective results via data gained before and after the practice course of laparoscopic simulator of the resident standardized trainees. Experiment 1: 20 resident standardized trainees with no experience in laparoscopic surgery were included in the inexperienced group and finished simulated cholecystectomy according to simulator videos. Simulator data was collected (total operation time, path length, average speed of instrument movement, movement efficiency, number of perforations, the time cautery is applied without appropriate contact with adhesions, number of serious complications). Ten attending doctors were included in the experienced group and conducted the operation of simulated cholecystectomy directly. Data was collected with simulator. Data of two groups was compared. Experiment 2: Participants in inexperienced group were assigned to basic group (receiving 8 items of basic operation training) and special group (receiving 8 items of basic operation training and 4 items of specialized training), and 10 persons for each group. They received training course designed by us respectively. After training level had reached the expected target, simulated cholecystectomy was performed, and data was collected. Experimental data between basic group and special group was compared and then data between special group and experienced group was compared. Results of experiment 1 showed that there is significant difference between data in inexperienced group in which participants operated simulated cholecystectomy only according to instructors' teaching and operation video and data in experienced group. Result of experiment 2 suggested that, total operation time, number of perforations, number of serious complications, number of non-cauterized bleeding and the time cautery is applied

  8. Endovascular procedures, carotid endarterectomies, and aortic surgery should preferentially be done by a vascular trainee rather than a general surgery resident. (United States)

    Seabrook, Gary R; Sharp, John


    This article is the result of a debate. The motion proposed was that "endovascular procedures, carotid endarterectomies, and aortic surgery should be done preferentially by a vascular trainee rather than a general surgery resident.'' Arguments in favor of the motion were that with the development of endovascular surgery, there are now less open vascular procedures to perform and hence, vascular trainees needed to hone their skills on these limited cases rather than waste that experience on a general surgery resident. This focused training experience would allow vascular fellows to be become more highly skilled vascular surgeons. Additionally, endovascular procedures are an important component of modern vascular surgery, and it is important for the vascular fellow to develop significant experience with and acquire the appropriate numbers of endovascular cases to get the necessary credentials when going into a vascular practice. Arguments against the motion were that exposure to vascular cases will make a better general surgeon, one who will also be well equipped to deal with trauma cases and situations where the control of bleeding might be life saving. Additionally, the issue of exposure of general surgery residents to vascular cases might be a positive recruitment strategy for future vascular fellows. The motion was carried by a small majority vote.

  9. The 88-hour family: effects of the 80-hour work week on marriage and childbirth in a surgical residency. (United States)

    Jones, Arden M; Jones, Kevin B


    The restriction of the resident physician work week to 80 hours has had dramatic affects on resident education and life-style. While effects on mood, psychological distress, and burn-out have been studied, the resultant changes in tangible quality of life have received little attention. Birth rate was considered a measurable, relevant outcome. The resident marital and parental status by duty month was collected from a single orthopaedic surgical residency program for the four academic years preceding and following the implementation of the 80-hour work week. The number of births to residents during these periods were also tallied. The relative prevalence of positive marital status changed very little between residents in the two time durations from 66 to 71 percent, but parental status increased from 27 to 43 percent. The number of births per married resident duty year also increased from 0.23 pre-restrictions to 0.32 post-restrictions. While the individual decisions involved in generating these observed changes are complex and difficult to entirely decipher, it is thought that an increased perception of life-control within the work-hour restrictions may have prompted the dramatic changes in birth rate among resident families.

  10. Resident training in urology: Bipolar transurethral resection of the prostate - a safe method in learning endoscopic surgical procedure

    Directory of Open Access Journals (Sweden)

    Alessandro Del Rosso


    Full Text Available Introduction: Modern medicine uses increasingly innovative techniques that require more and more capabilities for acquisition. In the urological department is increasing the presence of patients with lower urinary tract symptoms (LUTS and transurethral resection of the prostate (TURP is the standard of care in their surgical treatment. We report our surgical experience and learning curve of using bipolar plasmakinetic devices in the training of urological residents to benign prostatic hyperplasia (BPH treatment. Materials and Methods: 80 patients with benign prostatic enlargement due to BPH were enrolled in the study. TURP has been performed by three urological residents and by an expe- rienced urologist. Patients were evaluated before and 6 months after the endoscopic bipolar plasmakinetic resection using the International Prostate Symptom Score (IPSS, maximum uri- nary flow rate (Qmax, postvoid residual urine (PVR and prostate specific antigen (PSA. Results: Overall 60 procedures were performed, 18 PlasmaKinetic (PK-TURP procedures were completed by the three residents. In the other 42 cases the procedures were completed by the experienced urologist. In eight cases there was a capsular perforation and the experienced urol- ogist replaced the resident to complete the resection. No complications have been reported in the procedures completed by the senior urologist. All complications caused by the residents were man- aged intraoperatively without changing the course of the procedure. Statistical differences were observed regarding IPSS, quality of life (QoL, and PVR at 6-month follow-up when procedures completed by urological residents were compared to those completed by the senior urologist. Conclusion: Bipolar device represents appropriate tools to acquire endoscopic skills. It is safe and it can be used at the first experience of BPH treatment by a resident who has not previ- ously approached this endoscopic surgical procedure.

  11. A novel flight surgeon training model at a joint military and civilian surgical residency program. (United States)

    DeSoucy, Erik S; Zakaluzny, Scott A; Galante, Joseph M


    Graduating military preliminary interns are often required to fill flight surgeon billets. General surgery preliminary interns get experience evaluating surgical and trauma patients, but receive very little training in primary care and flight medicine. At a joint military and civilian training program, we developed a supplemental curriculum to help transition our interns into flight medicine. From 2013 to 2016, we developed a lecture series focused on aerospace medicine, primary care, and specialty topics including dermatology, ophthalmology, orthopedics, pediatrics, psychiatry, and women's health. During the 2016 iteration attended by 10 interns, pre- and post-participation 10-item Likert scale surveys were administered. Questions focused on perceived preparedness for primary care role and overall enthusiasm for flight medicine. Open-ended surveys from 2013 to 2016 were also used to gauge the effect of the curriculum. The composite number of agreement responses (indicating increased comfort with presented material) increased 63% after course completion. Disagreement responses and neutral responses decreased 78% and 30%, respectively. Open-ended surveys from 14 participants showed an overall positive impression of the curriculum with all indicating it aided their transition to flight medicine. Survey responses indicate an overall perceived benefit from participation in the curriculum with more confidence in primary care topics and improved transition to a flight medicine tour. This model for supplemental aerospace medicine and primary care didactics should be integrated into any residency program responsible for training military preliminary interns who may serve as flight surgeons.

  12. National trends in minimally invasive and open operative experience of graduating general surgery residents: implications for surgical skills curricula development? (United States)

    Carson, Jeffrey S; Smith, Lynette; Are, Madhuri; Edney, James; Azarow, Kenneth; Mercer, David W; Thompson, Jon S; Are, Chandrakanth


    The aim of this study was to analyze national trends in minimally invasive and open cases of all graduating residents in general surgery. A retrospective analysis was performed on data obtained from Accreditation Council for Graduate Medical Education logs (1999-2008) of graduating residents from all US general surgery residency programs. Data were analyzed using Mantel-Haenszel χ(2) tests and the Bonferroni adjustment to detect trends in the number of minimally invasive and open cases. Minimally invasive procedures accounted for an increasing proportion of cases performed (3.7% to 11.1%, P pediatric surgery (P surgery residents in the United States are performing a greater number of minimally invasive and fewer open procedures for common surgical conditions.

  13. Improving the quality of vascular surgical discharge planning in a hub centre. (United States)

    Wariyapola, C; Littlehales, E; Abayasekara, K; Fall, D; Parker, V; Hatton, G


    Introduction Discharge planning improves patient outcomes, reduces hospital stay and readmission rates, and should involve a multidisciplinary team (MDT) approach. The efficacy of MDT meetings in discharge planning was examined, as well as reasons for delayed discharge among vascular surgical inpatients. Methods Dedicated weekly MDT meetings were held on the vascular ward in Royal Derby Hospital for three months. Each patient was presented to the discharge planning meeting and an expected date of discharge was decided prospectively. Patients who were discharged after this date were considered 'delayed' and reasons for delay were explored at the next meeting. Results Overall, 193 patients were included in the study. Of these, 42 patients (22%) had a delayed discharge while 29 (15%) had an early discharge. The main reasons for delay were awaiting beds (30%), social (14%) and medical (45%). In 64%, the cause for delay was avoidable. Two-thirds (67%) of all delays were >24 hours. This totalled 115 bed days, of which 67 could have been avoided. However, 32 bed days were saved by early discharge. This equates to a net loss of 35 bed days, at a net cost of £2,936 per month or £35,235 per year. The MDT meetings also improved the quality of discharge planning; the variability between expected and actual discharge dates decreased after the first month. Conclusions Discharge planning meetings help prepare for patient discharge and are most effective with multidisciplinary input. The majority of delayed discharges from hospital are preventable. The main causes are awaiting transfers, social services input and medical reasons (eg falls). There is an obvious financial incentive to improve discharge planning. The efficiency of the MDT at discharge planning improves with time and this should therefore be continued for best results.

  14. Vascular Complications and Bleeding After Transfemoral Transcatheter Aortic Valve Implantation Performed Through Open Surgical Access. (United States)

    Leclercq, Florence; Akodad, Mariama; Macia, Jean-Christophe; Gandet, Thomas; Lattuca, Benoit; Schmutz, Laurent; Gervasoni, Richard; Nogue, Erika; Nagot, Nicolas; Levy, Gilles; Maupas, Eric; Robert, Gabriel; Targosz, Frederic; Vernhet, Hélène; Cayla, Guillaume; Albat, Bernard


    Major vascular complications (VC) remain frequent after transcatheter aortic valve implantation (TAVI) and may be associated with unfavorable clinical outcomes. The objective of this study was to evaluate the rate of VC after transfemoral TAVI performed using an exclusive open surgical access strategy. From 2010 to 2014, we included in a monocentric registry all consecutive patients who underwent transfemoral TAVI. The procedures were performed with 16Fr to 20Fr sheath systems. VC were evaluated within 30 days and classified as major or minor according to the Valve Academic Research Consortium 2 definition. The study included 396 patients, 218 were women (55%), median age was 85 years (81 to 88), and the median logistic Euroscore was 15.2% (11 to 23). The balloon-expandable SAPIEN XT and the self-expandable Medtronic Core Valve prosthesis were used in 288 (72.7%) and 108 patients (27.3%), respectively. The total length of the procedure was 68 ± 15 minutes including 13 ± 5 minutes for the open surgical access. Major and minor VC were observed in 9 (2.3%) and 16 patients (4%), respectively, whereas life-threatening and major bleeding concerned 18 patients (4.6%). The median duration of hospitalization was 5 days (interquartile range 2 to 7), significantly higher in patients with VC (7 days [5 to 15], p strategy, with a particular advantage observed in high-risk bleeding patients.

    Hohn, Eric A; Brooks, Adam G; Leasure, Jeremi; Camisa, William; van Warmerdam, Jennifer; Kondrashov, Dimitriy; Montgomery, William; McGann, William


    To develop and conduct a pilot study of a curriculum of 4 surrogate bone training modules to assess and track progress in basic orthopedic manual skills outside the operating room. Four training modules were developed with faculty and resident input. The modules include (1) cortical drilling, (2) drill trajectory, (3) oscillating saw, and (4) pedicle probing. Orthopedic resident's performance was evaluated. Validity and reliability results were calculated using standard analysis of variance and multivariate regression analysis accounting for postgraduate year (PGY) level, number of attempts, and specific outcome target results specific to the simulation module. St. Mary's Medical Center in San Francisco, CA. These modules were tested on 15 orthopedic surgery residents ranging from PGY 1 to PGY 5 experience. The cortical drilling module had a mean success rate of 56% ± 5%. There was a statistically significant difference in performance according to the diameter of the drill used from 33% ± 7% with large diameter to 70% ± 6% with small diameter. The drill trajectory module had a success rate of 85% ± 3% with a trend toward improvement across PGY level. The oscillating saw module had a mean success rate of 25% ± 5% (trajectory) and 84% ± 6% (depth). We observed a significant improvement in trajectory performance during the second attempt. The pedicle probing module had a success rate of 46% ± 10%. The results of this pilot study on a small number of residents are promising. The modules were inexpensive and easy to administer. Conclusions of statistical significance include (1) residents who could easily detect changes in surrogate bone thickness with a smaller diameter drill than with a larger diameter drill and (2) residents who significantly improved saw trajectory with an additional attempt at the module.

  16. The Canadian general surgery resident: defining current challenges for surgical leadership. (United States)

    Tomlinson, Corey; Labossière, Joseph; Rommens, Kenton; Birch, Daniel W


    Surgery training programs in Canada and the United States have recognized the need to modify current models of training and education. The shifting demographic of surgery trainees, lifestyle issues and an increased trend toward subspecialization are the major influences. To guide these important educational initiatives, a contemporary profile of Canadian general surgery residents and their impressions of training in Canada is required. We developed and distributed a questionnaire to residents in each Canadian general surgery training program, and residents responded during dedicated teaching time. In all, 186 surveys were returned for analysis (62% response rate). The average age of Canadian general surgery residents is 30 years, 38% are women, 41% are married, 18% have dependants younger than 18 years and 41% plan to add to or start a family during residency. Most (87%) residents plan to pursue postgraduate education. On completion of training, 74% of residents plan to stay in Canada and 49% want to practice in an academic setting. Almost half (42%) of residents identify a poor balance between work and personal life during residency. Forty-seven percent of respondents have appropriate access to mentorship, whereas 37% describe suitable access to career guidance and 40% identify the availability of appropriate social supports. Just over half (54%) believe the stress level during residency is manageable. This survey provides a profile of contemporary Canadian general surgery residents. Important challenges within the residency system are identified. Program directors and chairs of surgery are encouraged to recognize these challenges and intervene where appropriate.

  17. [The characteristics of vascular psychoses in the residents of Chernivtsi Province]. (United States)

    Rusina, S M


    Vascular affections of the brain remain a formidable psychiatric challenge nowadays. According to WHO reports cerebrovascular disorders constitute one of the three chief causes of mortality in the population of the economically developed countries of the world. The most important cause of vascular psychoses is considered to be atherosclerosis and hypertensive disease. Today vascular psychoses have become a most common type of abnormal mental states in young adults (greater then 30-40 years old). The studies made have yielded evidence in support of the psychoses morbidity to be dependent upon particular season of year as well as on the climatic features of the locality. Natural factors have been found out to affect the prevalence of vascular psychoses in Chernivtsi Province. The findings obtained suggest to us a substantial prevalence of atherosclerotic and hypertensive psychoses in the plains-men living under conditions of a mild climate.

    Abdulrasheed Ibrahim


    Full Text Available Background: The transformation of a surgical trainee into a surgeon is strongly influenced by the quality of teaching in the operating theater. This study investigates the perceptions of residents about the educational environment of the operating theater and identifies variables that may improve the operating theater education of our trainees. Materials and Methods: Residents in the department of surgery anonymously evaluated teaching in the operating room using the operating theater education environment measure. The residents evaluated 33 variables that might have an impact on their surgical skills within the operating theater. The variables were grouped into four subscales; teaching and training, learning opportunities, operating theater atmosphere and workload/supervision/support. Differences between male and female residents and junior and senior registrars were assessed using Mann-Whitney test. Statistical analysis was completed with the statistics package for the social sciences version 17. Results: A total of 33 residents were participated in this study. Twenty nine (88% males and 4 (12% females. 30 (90% were junior registrars. The mean total score was 67.5%. Operating theater atmosphere subscale had the highest score of 79.2% while workload/supervision/support subscale had the least score of 48.3%. There were significant differences between male and female resident′s perception of workload/supervision/support P 0.05. Conclusion: This study has shown a satisfactory teaching environment based on the existing local realities of means, resources and tools and highlighted the need for improvement in workload/supervision/support in our institution. An acceptable learning environment in the operating theatre will produce surgeons that are technically competent to bridge the gap in the enormous unmet need for surgical care in Nigeria.

  19. Can teenage novel users perform as well as General Surgery residents upon initial exposure to a robotic surgical system simulator? (United States)

    Mehta, A; Patel, S; Robison, W; Senkowski, T; Allen, J; Shaw, E; Senkowski, C


    New techniques in minimally invasive and robotic surgical platforms require staged curricula to insure proficiency. Scant literature exists as to how much simulation should play a role in training those who have skills in advanced surgical technology. The abilities of novel users may help discriminate if surgically experienced users should start at a higher simulation level or if the tasks are too rudimentary. The study's purpose is to explore the ability of General Surgery residents to gain proficiency on the dVSS as compared to novel users. The hypothesis is that Surgery residents will have increased proficiency in skills acquisition as compared to naive users. Six General Surgery residents at a single institution were compared with six teenagers using metrics measured by the dVSS. Participants were given two 1-h sessions to achieve an MScoreTM in the 90th percentile on each of the five simulations. MScoreTM software compiles a variety of metrics including total time, number of attempts, and high score. Statistical analysis was run using Student's t test. Significance was set at p value technology.

  20. Reflections in a time of transition: orthopaedic faculty and resident understanding of accreditation schemes and opinions on surgical skills feedback

    Directory of Open Access Journals (Sweden)

    Kenneth R. Gundle


    Full Text Available Introduction: Orthopaedic surgery is one of the first seven specialties that began collecting Milestone data as part of the Accreditation Council for Graduate Medical Education's Next Accreditation System (NAS rollout. This transition from process-based advancement to outcome-based education is an opportunity to assess resident and faculty understanding of changing paradigms, and opinions about technical skill evaluation. Methods: In a large academic orthopaedic surgery residency program, residents and faculty were anonymously surveyed. A total of 31/32 (97% residents and 29/53 (55% faculty responded to Likert scale assessments and provided open-ended responses. An internal end-of-rotation audit was conducted to assess timeliness of evaluations. A mixed-method analysis was utilized, with nonparametric statistical testing and a constant-comparative qualitative method. Results: There was greater familiarity with the six core competencies than with Milestones or the NAS (p<0.05. A majority of faculty and residents felt that end-of-rotation evaluations were not adequate for surgical skills feedback. Fifty-eight per cent of residents reported that end-of-rotation evaluations were rarely or never filled out in a timely fashion. An internal audit demonstrated that more than 30% of evaluations were completed over a month after rotation end. Qualitative analysis included themes of resident desire for more face-to-face feedback on technical skills after operative cases, and several barriers to more frequent feedback. Discussion: The NAS and outcome-based education have arrived. Residents and faculty need to be educated on this changing paradigm. This transition period is also a window of opportunity to address methods of evaluation and feedback. In our orthopaedic residency, trainees were significantly less satisfied than faculty with the amount of technical and surgical skills feedback being provided to trainees. The quantitative and qualitative analyses

  1. Comparative effectiveness of peripheral vascular intervention versus surgical bypass for critical limb ischemia in the Vascular Study Group of Greater New York. (United States)

    Meltzer, Andrew J; Sedrakyan, Art; Isaacs, Abby; Connolly, Peter H; Schneider, Darren B


    In this study, the effectiveness of peripheral vascular intervention (PVI) was compared with surgical bypass grafting (BPG) for critical limb ischemia (CLI) in the Vascular Study Group of Greater New York (VSGGNY). Patients undergoing BPG or PVI for CLI at VSGGNY centers (2011-2013) were included. The Society for Vascular Surgery objective performance goals for CLI were used to directly compare the safety and effectiveness of PVI and BPG. Propensity score matching was used for risk-adjusted comparisons of PVI with BPG. A total of 414 patients (268 PVI, 146 BPG) were treated for tissue loss (69%) or rest pain (31%). Patients undergoing PVI were more likely to have tissue loss (74.6% vs 57.5%; P PVI was associated with improved freedom from major adverse limb events and postoperative death at 1 year (95.6% vs 88.5%; P PVI. However, risk-adjusted comparison underscores the safety and effectiveness of PVI in the treatment of CLI. Copyright © 2016 Society for Vascular Surgery. Published by Elsevier Inc.

  2. Adrenomedullin Is Associated With Surgical Trauma and Impaired Renal Function in Vascular Surgery Patients. (United States)

    Gillmann, Hans-Jörg; Meinders, Antje; Larmann, Jan; Sahlmann, Bianca; Schrimpf, Claudia; Aper, Thomas; Lichtinghagen, Ralf; Teebken, Omke E; Theilmeier, Gregor


    Patients undergoing vascular surgery are prone to perioperative organ injury because of both higher prevalence of cardiovascular risk factors and the extent of surgery. Early detection of organ failure is essential to facilitate appropriate medical care. Midregional pro-adrenomedullin (MR-proADM) has been investigated in acute medical care settings to guide clinical decision-making regarding patient pathways and to identify patients prone to imminent cardiovascular or inflammatory complications. In this study, we evaluated the impact of perioperative MR-proADM levels as an early marker of perioperative cardiovascular and inflammatory stress reactions and kidney injury. The study was conducted as a monocentric, prospective, noninterventional trial at Hannover Medical School, Germany. A total of 454 consecutive patients who underwent open vascular surgery were followed from the day prior to until 30 days after surgery. The composite primary end point was defined as the occurrence of major adverse cardiac events (MACEs), acute kidney injury (AKI), or systemic inflammatory response syndrome (SIRS). Measurements were correlated with both medical history and postoperative MACE, AKI, or SIRS using univariate and multivariate regression analysis. One hundred thirty-nine (31%) of the patients reached the primary end point within the study interval. Midregional pro-adrenomedullin change was associated with the combined primary end point and with the intensity of surgical trauma. Midregional pro-adrenomedullin change was increased in patients reaching the secondary end points, SIRS (optimal cutoff: 0.2 nmol/L) and AKI (optimal cutoff: 0.7 nmol/L), but not in patients with MACEs. Increased levels of MR-proADM within the perioperative setting (1) were linked to the invasiveness of surgery and (2) identified patients with ongoing loss of renal function. Increased MR-proADM levels may therefore identify a subgroup of patients prone to excessive cardiovascular stress but did not

    Neoadjuvant chemotherapy (NACT),which can reduce the size and therefore increase the resectability of tumors,has recently evolved as a treatment for locally advanced cervical cancer.NACT has been reported to decrease the risk of pathologic factors related to prognosis of cervical cancer.To further assess the effects of NACT on surgery and the pathologic characteristics of cervicat cancer,we reviewed 110 cases of locally advanced cervical cancer treated with radical hysterectomy with or without NACT at the People's Hospital of Peking University between January 2006 and December 2010.Of 110 patients,68 underwent platinum-based NACT prior to surgery (NACT group) and 42 underwent pdmary surgery treatment (PST group).Our results showed 48 of 68 (70.6%) patients achieved a complete response or partial response to NACT.Estimated blood loss,operation time,and number of removed lymph nodes during surgery,as well as complication rates during and after surgery were not significantly different between the NACT group and the PST group.The rates of deep stromal invasion,positive parametria,positive surgical vaginal margins,and lymph node metastasis were not significantly different between the two groups.However,the rate of lymph-vascular space involvement (LVSI) was significantly lower in the NACT group than in the PST group (P = 0.021).In addition,the response rate of NACT was significantly higher in the patients with chemotherapeutic drugs administrated via artery than via vein.Our results suggest that NACT is a safe and effective treatment for locally advanced cervical cancer and significantly decreases the rate of LVSI.

    Full Text Available Settings and Design: This study documents a survey of final-year ophthalmology postgraduates on the subject of their surgical training and their future plans after residency. Purpose: This survey aimed to answer the question, "What is the present status of surgical training in ophthalmic training centers?" by obtaining information from students about (1 various methods used in surgical training (2 numbers and types of surgeries performed by them in the training centers (3 their plans after residency. Materials and Methods: A questionnaire containing 21 questions was distributed to 155 students attending an intensive 4-day teaching program. The questions related to orientation training, wet lab training, facilities for training, free surgical camps and detailed information about numbers and types of surgeries observed and performed. Completed questionnaires were collected, and responses analyzed. Results: One hundred and seven completed responses were analyzed. The majority had not received formal orientation training. More than half had undergone wet lab training. Most residents performed their first ophthalmic surgery during the 1 st year of residency and went to the operation theatre multiple times a week. Most of the students planned to undergo further training after residency. More than half of the students found their surgical training to be fair or satisfactory. Conclusions: The number and frequency of ophthalmic surgeries done by residents appear satisfactory, but further efforts from trainers on enhancing the quality and range of surgical training would benefit students and improve their satisfaction.

  5. Vascular Remodelling Relates to an Elevated Oscillatory Shear Index and Relative Residence Time in Spontaneously Hypertensive Rats. (United States)

    Chen, Zhiyan; Yu, Haiyi; Shi, Yue; Zhu, Minjia; Wang, Yueshen; Hu, Xi; Zhang, Youyi; Chang, Yu; Xu, Ming; Gao, Wei


    Haemodynamic disorders are common clinical findings in hypertension and lead to adverse cardiovascular events. However, the haemodynamic conditions in hypertension models are poorly understood. This study aimed to observe the characteristics of haemodynamics in spontaneously hypertensive rats (SHRs) and antihypertensive-treated SHRs. Twenty-four adult male SHRs and Wistar-Kyoto rats (WKYs) were randomly divided into four groups and treated for 7 days as follows: WKY-CON (WKYs + saline), WKY-NIF (WKYs + nifedipine, 50 mg/kg/day), SHR-CON (SHRs + saline), and SHR-NIF (SHRs + nifedipine). Aortic computational fluid dynamics (CFD) models were simulated to obtain the haemodynamic parameters. We found that in the hypertensive (SHR-CON) and blood pressure-controlled (SHR-NIF) groups, the oscillatory shear index (OSI) and relative residence time (RRT), which are key haemodynamics indices, were markedly elevated. Furthermore, there was a correlation between both the elevated OSI and RRT with the vascular wall thickening in regions near the inner wall of the aortic arch. Our research demonstrates that haemodynamics remains disturbed even if the blood pressure is normalized. In addition, vascular remodelling may play an important role in maintaining elevated OSI and RRT values.

  6. Surgical Residency Training at a University-Based Academic Medical Center. (United States)

    Hoffman, Rebecca L; Morris, Jon B; Kelz, Rachel R


    The past two decades have been witness to some of the most dynamic changes that have occurred in surgical education in all of its history. Political policies, social revolution, and the competing priorities of a new generation of surgical trainees are defining the needs of modern training paradigms. Although the university-based academic program's tripartite mission of clinical service, research, and education has remained steadfast, the mechanisms for achieving success in this mission necessitate adaptation and innovation. The resource-rich learning environment and the unique challenges that face university-based programs contribute to its ability to generate the future leaders of the surgical workforce.

    AND METHODS: fifty charts of patients that were submitted to a total of 51 primary stapedotomies were reviewed mainly for complications and audiological results. RESULTS: there was closure of the air-bone gap within 10 dB HL in 70.5% of ears and closure to within 20 dB HL in 86.3% of ears. There was one ear with total hearing loss (2%. CONCLUSION: From the results and complications seen in the present study, and analyzing papers from the literature, it is possible to conclude that stapedotomy is a procedure that can be included in residency programs, if there are surgical cases for the residents.

  8. Increasing functional modularity with residence time in the co-distribution of native and introduced vascular plants (United States)

    Hui, Cang; Richardson, David M.; Pyšek, Petr; Le Roux, Johannes J.; Kučera, Tomáš; Jarošík, Vojtěch


    Species gain membership of regional assemblages by passing through multiple ecological and environmental filters. To capture the potential trajectory of structural changes in regional meta-communities driven by biological invasions, one can categorize species pools into assemblages of different residence times. Older assemblages, having passed through more environmental filters, should become more functionally ordered and structured. Here we calculate the level of compartmentalization (modularity) for three different-aged assemblages (neophytes, introduced after 1500 AD; archaeophytes, introduced before 1500 AD, and natives), including 2,054 species of vascular plants in 302 reserves in central Europe. Older assemblages are more compartmentalized than younger ones, with species composition, phylogenetic structure and habitat characteristics of the modules becoming increasingly distinctive. This sheds light on two mechanisms of how alien species are functionally incorporated into regional species pools: the settling-down hypothesis of diminishing stochasticity with residence time, and the niche-mosaic hypothesis of inlaid neutral modules in regional meta-communities.

    Mohd Lateef Wani


    Full Text Available Background: Tear gas shells are used to disperse the mob during any type of street protests. Vascular injuries due to tear gas shells have not been reported. The present study was un-dertaken to analyse the pattern, presentation, management and outcome of vascular injury due to tear gas shells. Methods: Eighteen patients with vascular injury caused by tear gas shells from 1st Jan. 2008 to 31st Dec 2009 were studied. Patients with vascular injuries caused by causes other than tear gas shells were excluded from the study. Results: All patients were treated with reverse saphenous vein graft as segmental loss was less than 2.5 cm. Wound infection was the most common complication, followed by graft occlusion. Amputation rate was 16.66%. Associated nerve injury occurred in 44.44% of the patients. Conclusion: Tear gas shell injuries should not be taken lightly. They can cause injuries as serious as vascular injuries. Vascular injuries cased by tear gas shells require prompt revascularisation to improve limb salvage. De-spite proper revascularisation, patients have significant morbidity and need proper rehabilitation in the follow ups.

  12. Surgical repair following trauma to vascular graft causing spinal cord infarction (United States)

    Vivekanantham, Sayinthen; Phoenix, Gokulan; Khatri, Chetan; Das, Saroj


    A 55-year-old woman with a background of vascular disease presented with signs of bilateral limb ischaemia. Following elective axillobifemoral bypass and hospital discharge, accidental axillary trauma causing a chest wall haematoma, the patient underwent an emergency graft repair. Postextubation, she reported with absent sensation in her legs. Spinal cord infarction was diagnosed through clinical assessment and exclusion of other causes. The aetiology of compromise to the spinal cord blood supply is unclear. Possibilities include intraoperative hypotension, inadvertent compromise to blood supply of thoracic radicular arteries, dislodged atherosclerotic emboli or a combination of these factors. Spinal cord infarction recognised early can be treated. Sedation to assist ventilation had obscured the problem early enough to consider treatment. Patients with vascular risk factors should be carefully managed intraoperatively to minimise hypotensive episodes and care should also be taken not to compromise blood flow of radicular arteries.

  13. Factors associated with surgical site infection after lower extremity bypass in the Society for Vascular Surgery (SVS) Vascular Quality Initiative (VQI). (United States)

    Kalish, Jeffrey A; Farber, Alik; Homa, Karen; Trinidad, Magdiel; Beck, Adam; Davies, Mark G; Kraiss, Larry W; Cronenwett, Jack L


    Surgical site infection (SSI) is a major source of morbidity after infrainguinal lower extremity bypass (LEB). This study examines processes of care associated with in-hospital SSI after LEB and identifies factors that could potentially be modified to improve outcomes. The Society for Vascular Surgery (SVS) Vascular Quality Initiative (VQI) registry (2003 to 2012) was queried to identify in-hospital SSI after 7908 consecutive LEB procedures performed by 365 surgeons at 91 academic and community hospitals in 45 states. Variables associated with SSI were identified using multivariable logistic regression and hierarchical clustering. Expected and observed SSI rates were calculated for each hospital. The overall in-hospital SSI rate after LEB was 4.8%. Univariate analysis showed that obesity, dialysis, tissue loss, preoperative ankle-brachial index 2 units of packed red blood cells, procedure time >220 minutes, and estimated blood loss >100 mL were associated with higher SSI rates, whereas chlorhexidine (compared with iodine) skin preparation was protective. Multivariable analysis showed independent predictors of SSI included ankle-brachial index 2 units (OR, 3.30; 95% CI, 2.17-5.02; P 220 minutes (OR, 2.11; 95% CI, 1.05-4.23; P < .04). Chlorhexidine was protective against SSI (OR, 0.53; 95% CI, 0.35-0.79; P = .002). Stratified analyses based on the presence of tissue loss yielded similar results. Across VQI hospitals, observed SSI rates ranged from 0% to 30%, whereas expected SSI rates adjusted by the four independent predictors ranged from 0% to 7.2%. In-hospital SSI after LEB varies substantially across VQI hospitals. Three modifiable processes of care (transfusion rate, procedure time, and type of skin preparation) were identified and may be used by hospitals to reduce SSI rates. This study demonstrates the value of the SVS VQI detailed shared clinical registry to identify improvement opportunities directly pertinent to providers that are not available in

    Schulz, Kristine; Puscas, Liana; Tucci, Debara; Woodard, Charles; Witsell, David; Esclamado, Ramon M; Lee, Walter T


    Surgical Training and Education in Promoting Professionalism (STEPP) was developed in 2011 to train tomorrow's leaders during residency. It is based on virtue ethics and takes an approach similar to West Point military academy. The purpose of this research was: (i) to compare the virtue profiles of our residents with that of the military cohort using a standardized virtue assessment tool; and (ii) to assess the value of virtue education on residents. As part of STEPP, otolaryngology residents participated in a virtue-based validated assessment tool called Virtue in Action (VIA) Inventory. This was completed at the initiation of STEPP in July 2011 as well as 1 year later in June 2012. Comparison of the VIA to a military cohort was performed. Leadership 'Basic Training' is a series of forums focused on virtues of initiative, integrity, responsibility, self-discipline, and accountability. A pre- and post-test was administered assessing resident perceptions of the value of this 'Basic Training'. Virtues are shared between otolaryngology residents (n=9) and military personnel (n=2,433) as there were no significant differences in strength scores between two military comparison groups and otolaryngology-head and neck surgery (OHNS) residents. There was a significant improvement (pvirtue-based approach is valued by residents as a part of leadership training during residency.

    To design and implement a teaching skills curriculum that addressed the needs of an ophthalmology residency training program, to assess the effect of the curriculum, and to present important lessons learned. A teaching skills curriculum was designed for the Harvard Medical School (HMS) Residency Training Program in Ophthalmology. Results of a needs assessment survey were used to guide curriculum objectives. Overall, 3 teaching workshops were conducted between October 2012 and March 2013 that addressed areas of need, including procedural teaching. A postcurriculum survey was used to assess the effect of the curriculum. Massachusetts Eye and Ear Infirmary, a tertiary care institution in Boston, MA. Overall, 24 residents in the HMS Residency Training Program in Ophthalmology were included. The needs assessment survey demonstrated that although most residents anticipated that teaching would be important in their future career, only one-third had prior formal training in teaching. All residents reported they found the teaching workshops to be either very or extremely useful. All residents reported they would like further training in teaching, with most residents requesting additional training in best procedural teaching practices for future sessions. The pilot year of the resident-as-teacher curriculum for the HMS Residency Training Program in Ophthalmology demonstrated a need for this curriculum and was perceived as beneficial by the residents, who reported increased comfort in their teaching skills after attending the workshops.

    Vascularized lymph node transfer is an effective surgical method in reducing lymphedema. This study provides the first detailed description of the surgical anatomy of the supraclavicular lymph node flap in regard to pedicle length, pedicle diameter, and the number of lymph nodes and their exact location inside the flap. Bilateral supraclavicular dissections of nine fresh cadavers (five female) were performed. Before the dissection, the exact number of lymph nodes was determined sonographically by an experienced radiologist, and their distance from the jugular notch was measured. After anatomic dissection, the vascular pedicle's diameter and length were measured. The mean number of lymph nodes was 1.5 ± 1.85 on the right side and 3 ± 2.26 on the left. Their mean distance from the jugular notch was 8.29 ± 2.15 cm on the right and 6.10 ± 1.21 cm on the left. The pedicle's length was 4.72 ± 1.03 cm on the right and 4.86 ± 0.99 cm on the left, and its diameter 2.03 ± 0.83 on the right and 1.80 ± 0.77 on the left. The pedicle length and diameter of the supraclavicular lymph node flap are suitable for a microvascular tissue transfer. J. Surg.

  17. Stress and burnout in colorectal and vascular surgical consultants working in the UK National Health Service. (United States)

    Sharma, A; Sharp, D M; Walker, L G; Monson, J R T


    It has been suggested that dealing with cancer is associated with increased stress and burnout in health-care professionals. The aim of this study is to examine the prevalence of psychiatric morbidity and burnout in surgeons working in the National Health Service (NHS), and the putative relationship between psychiatric morbidity, burnout and the amount of cancer-related work. All consultant colorectal and vascular surgeons identified from their professional societies were sent a booklet consisting of questions about cancer-related and specialty-specific work load, job satisfaction and socio-demographics. It also included the General Health Questionnaire (GHQ-12), the Maslach Burnout Inventory (MBI) and the Coping Questionnaire. Logistic regression analysis was used to identify independent predictors of psychiatric morbidity (GHQ), burnout (MBI) and retirement intentions. Five hundred and one questionnaire booklets were completed and returned (response rate 58.7%). The mean age of respondents was 47 years (range 31-65). The majority of the surgeons were male (460, 92%). One hundred and sixty-three (33%) surgeons scored in the positive range of the GHQ, and 154 (32%) had high burnout on at least one subscale of the MBI. Three hundred and eighty-three (77%) surgeons stated that they intended to retire before the statutory retirement age. Level of work satisfaction and perceived adequacy of training in communication and management skills were significantly negatively correlated with GHQ and MBI scores. Surgeons who planned to take early retirement or wished to retire as soon as they could afford to were more likely to have psychiatric morbidity and/or burnout. Surgeons who were married or cohabiting were less likely to have psychiatric morbidity, and younger surgeons were more likely to have higher levels of depersonalization (DP). Work satisfaction was negatively correlated with psychiatric morbidity and all three burnout scales. Colorectal surgeons had a greater

    麻鹏; 刘春丽


    As a key mediator of normal physiological angiogenesis,vascular endothelial growth factor(VEGF)has been regarded as an emancipator to plastic surgeon,and yet a misfortune to oncology surgeon,due to its sin-gular biological effect.Therefore in some clinical cases,especially for some malignant tumor patients having en-dured radical surgery and being craving for a reconstructive surgery,VEGF plays a role full of paradoxes.To make a clinical balance,we should find a point to inhibit tumor cell from utilizing VEGF and make a permission to normal tissues to employ it.

    King, Anthony P.; Abelson, James L.; Gholami, Bardia; Upchurch, Gilbert R.; Henke, Peter; Graham, Linda; Liberzon, Israel


    Objective Major life stressors, including major surgeries, are often followed by psychiatric symptoms and disorders. Prior retrospective work found abdominal-aortic aneurysm (AAA) repair is followed by increased psychiatric morbidity, which may adversely influence physical and functional recovery. Identifying risk factors prior to surgery, such as dysregulation in stress response systems, might be useful to improving preventative intervention. Methods Two hundred and sixteen patients receiving open AAA or aortofemoral bypass (AFB) surgeries, endovascular AAA repair (EVAR), or nonsurgical AAA treatment were recruited from two vascular surgery services. Psychiatric symptoms and salivary cortisol measures (waking, 4 pm, and 11 pm, before and after low-dose dexamethasone) were obtained at intake and 3 and 9 month followups. Results Following open surgeries, 18% of patients had new psychiatric disorders, compared to 4% of patients receiving EVAR or nonsurgical treatment (odds ratio = 6.0, 95% CI 1.6 - 22.1, p=.007). Having a history of major depression predicted onset of new disorders in surgical patients. Pre-surgical cortisol levels were associated with both baseline (r=.23, p<.05) and 9 month (r=.32, p<.01) psychiatric symptoms (cortisol B=1.0, SE=0.48, p<.05 in repeated measures mixed model). Conclusion Open AAA repair surgery is prospectively linked to development of psychiatric morbidity, and history of depression elevates risk. Cortisol measures prior to surgery are associated with current and future psychological functioning, suggesting potential neurobiological mechanisms that may contribute to vulnerability. These results can help identify surgical patients at risk, and point to potential targets for risk reduction interventions. PMID:26461854

  3. The surgical experience of general surgery residents: an analysis of the applicability of the specialty program in General and Digestive Surgery. (United States)

    Targarona Soler, Eduardo Ma; Jover Navalon, Jose Ma; Gutierrez Saiz, Javier; Turrado Rodríguez, Víctor; Parrilla Paricio, Pascual


    Residents in our country have achieved a homogenous surgical training by following a structured residency program. This is due to the existence of specific training programs for each specialty. The current program, approved in 2007, has a detailed list of procedures that a surgeon should have performed in order to complete training. The aim of this study is to analyze the applicability of the program with regard to the number of procedures performed during the residency period. A data collection form was designed that included the list of procedures from the program of the specialty; it was sent in April 2014 to all hospitals with accredited residency programs. In September 2014 the forms were analysed, and a general descriptive study was performed; a subanalysis according to the resident's sex and Autonomous region was also performed. The number of procedures performed according to the number of residents in the different centers was also analyzed. The survey was sent to 117 hospitals with accredited programs, which included 190 resident places. A total of 91 hospitals responded (53%). The training offered adapts in general to the specialty program. The total number of procedures performed in the different sub-areas, in laparoscopic and emergency surgery is correct or above the number recommended by the program, with the exception of esophageal-gastric and hepatobiliary surgery. The sub-analysis according to Autonomous region did not show any significant differences in the total number of procedures, however, there were significant differences in endocrine surgery (P=.001) and breast surgery (P=.042). A total of 55% of residents are female, with no significant differences in distribution in Autonomous regions. However, female surgeons operate more than their male counterparts during the residency period (512±226 vs. 625±244; P<.01). The number of residents in the hospital correlates with the number of procedures performed; the residents with more procedures

    de Lesquen, Henri; Avaro, Jean-Philippe; Gust, Lucile; Ford, Robert Michael; Beranger, Fabien; Natale, Claudia; Bonnet, Pierre-Mathieu; D'Journo, Xavier-Benoît


    This review aims to answer the most common questions in routine surgical practice during the first 48 h of blunt chest trauma (BCT) management. Two authors identified relevant manuscripts published since January 1994 to January 2014. Using preferred reporting items for systematic reviews and meta-analyses statement, they focused on the surgical management of BCT, excluded both child and vascular injuries and selected 80 studies. Tension pneumothorax should be promptly diagnosed and treated by needle decompression closely followed with chest tube insertion (Grade D). All traumatic pneumothoraces are considered for chest tube insertion. However, observation is possible for selected patients with small unilateral pneumothoraces without respiratory disease or need for positive pressure ventilation (Grade C). Symptomatic traumatic haemothoraces or haemothoraces >500 ml should be treated by chest tube insertion (Grade D). Occult pneumothoraces and occult haemothoraces are managed by observation with daily chest X-rays (Grades B and C). Periprocedural antibiotics are used to prevent chest-tube-related infectious complications (Grade B). No sign of life at the initial assessment and cardiopulmonary resuscitation duration >10 min are considered as contraindications of Emergency Department Thoracotomy (Grade C). Damage Control Thoracotomy is performed for either massive air leakage or refractive shock or ongoing bleeding enhanced by chest tube output >1500 ml initially or >200 ml/h for 3 h (Grade D). In the case of haemodynamically stable patients, early video-assisted thoracic surgery is performed for retained haemothoraces (Grade B). Fixation of flail chest can be considered if mechanical ventilation for 48 h is probably required (Grade B). Fixation of sternal fractures is performed for displaced fractures with overlap or comminution, intractable pain or respiratory insufficiency (Grade D). Lung herniation, traumatic diaphragmatic rupture and pericardial rupture are life

  11. Use of 3D printer technology to facilitate surgical correction of a complex vascular anomaly with esophageal entrapment in a dog. (United States)

    Dundie, A; Hayes, G; Scrivani, P; Campoy, L; Fletcher, D; Ash, K; Oxford, E; Moïse, N S


    A 10 week old female intact Staffordshire terrier was presented with a total of five congenital cardio-thoracic vascular anomalies consisting of a patent ductus arteriosus (PDA) with an aneurysmic dilation, pulmonic stenosis, persistent right aortic arch, aberrant left subclavian artery and persistent left cranial vena cava. These abnormalities were identified with a combination of echocardiogram and computed tomography angiography (CTA). The abnormalities were associated with esophageal entrapment, regurgitation, and volume overload of the left heart with left atrial and ventricular enlargement. A 2 cm diameter aneurysmic dilation at the junction of the PDA, right aortic arch and aberrant left subclavian artery presented an unusual surgical challenge and precluded simple circumferential ligation and transection of the structure. A full scale three dimensional model of the heart and vasculature was constructed from the CTA and plasma sterilized. The model was used preoperatively to facilitate surgical planning and enhance intraoperative communication and coordination between the surgical and anesthesia teams. Intraoperatively the model facilitated spatial orientation, atraumatic vascular dissection, instrument sizing and positioning. A thoracoabdominal stapler was used to close the PDA aneurysm prior to transection. At the four-month postoperative follow-up the patient was doing well. This is the first reported application of new imaging and modeling technology to enhance surgical planning when approaching correction of complex cardiovascular anomalies in a dog.

  12. Communication skills training in surgical residency: a needs assessment and metacognition analysis of a difficult conversation objective structured clinical examination. (United States)

    Falcone, John L; Claxton, René N; Marshall, Gary T


    The objective structured clinical examination (OSCE) can be used to evaluate the Accreditation Council for Graduate Medical Education Core Competencies of Professionalism and Interpersonal and Communication Skills. The aim of this study was to describe general surgery resident performance on a "difficult conversation" OSCE. In this prospective study, junior and senior residents participated in a 2-station OSCE. Junior stations involved discussing operative risks and benefits and breaking bad news. Senior stations involved discussing goals of care and discussing transition to comfort measures only status. Residents completed post-OSCE checklist and Likert-based self-evaluations of experience, comfort, and confidence. Trained standardized patients (SPs) evaluated residents using communication skill-based checklists and Likert-based assessments. Pearson correlation coefficients were determined between self-assessment and SP assessment. Mann-Whitney U tests were conducted between junior and senior resident variables, using α = 0.05. There were 27 junior residents (age 28.1 ± 1.9 years [29.6% female]) and 27 senior residents (age 32.1 ± 2.5 years [26.9% female]). The correlation of self-assessment and SP assessment of overall communication skills by junior residents was -0.32 on the risks and benefits case and 0.07 on the breaking bad news case. The correlation of self-assessment and SP assessment of overall communication skills by senior residents was 0.30 on the goals of care case and 0.26 on the comfort measures only case. SP assessments showed that junior residents had higher overall communication skills than senior residents (p = 0.03). Senior residents perceived that having difficult conversations was more level appropriate (p skills are correlated, and that skills-based training is needed across all residency levels. This well-received method may be used to observe, document, and provide resident feedback for these important skills. © 2014 Published by

  13. Association Between Flexible Duty Hour Policies and General Surgery Resident Examination Performance: A Flexibility in Duty Hour Requirements for Surgical Trainees (FIRST) Trial Analysis. (United States)

    Blay, Eddie; Hewitt, D Brock; Chung, Jeanette W; Biester, Thomas; Fiore, James F; Dahlke, Allison R; Quinn, Christopher M; Lewis, Frank R; Bilimoria, Karl Y


    Concerns persist about the effect of current duty hour reforms on resident educational outcomes. We investigated whether a flexible, less-restrictive duty hour policy (Flexible Policy) was associated with differential general surgery examination performance compared with current ACGME duty hour policy (Standard Policy). We obtained examination scores on the American Board of Surgery In-Training Examination, Qualifying Examination (written boards), and Certifying Examination (oral boards) for residents in 117 general surgery residency programs that participated in the Flexibility in Duty Hour Requirements for Surgical Trainees (FIRST) Trial. Using bivariate analyses and regression models, we compared resident examination performance across study arms (Flexible Policy vs Standard Policy) for 2015 and 2016, and 1 year of the Qualifying Examination and Certifying Examination. Adjusted analyses accounted for program-level factors, including the stratification variable for randomization. In 2016, FIRST trial participants were 4,363 general surgery residents. Mean American Board of Surgery In-Training Examination scores for residents were not significantly different between study groups (Flexible Policy vs Standard Policy) overall (Flexible Policy: mean [SD] 502.6 [100.9] vs Standard Policy: 502.7 [98.6]; p = 0.98) or for any individual postgraduate year level. There was no difference in pass rates between study arms for either the Qualifying Examination (Flexible Policy: 90.4% vs Standard Policy: 90.5%; p = 0.99) or Certifying Examination (Flexible Policy: 86.3% vs Standard Policy: 88.6%; p = 0.24). Results from adjusted analyses were consistent with these findings. Flexible, less-restrictive duty hour policies were not associated with differences in general surgery resident performance on examinations during the FIRST Trial. However, more years under flexible duty hour policies might be needed to observe an effect. Copyright © 2016 American College of Surgeons

Methods The clinical data of 17 patients suffering from limb prosthetic vascular graft exposure in Peking Union Medical College Hospital from August 2006 to December 2011 were retrospectively analyzed. Among 17 cases, 5 suffered from prosthetic vascular graft exposure after vascular bypass for the lower limb ischemia, whereas 12 were affected after the artificial graft arteriovenous fistula construction in the upper limbs for hemodialysis. The surgical procedures mainly included the local debridement as well as the local flap and transferred muscle-cutaneous flap reconstruction to preserve the prosthetic vascular graft. Results All 17 patients underwent local flap or muscle-cutaneous flap coverage procedure. After the surgery, the prosthetic vascular graft was successfully salvaged in 14 cases. The total successful rate was 82. 4%. The surgery failed in three patients, in whom the prosthetic vascular grafts were finally removed. Conclusion Local flap and transferred muscle-cutaneous flap reconstruction is an effective surgical management to salvage the exposed grafts.

  15. Abolishment of 24-hour continuous medical call duty in quebec: a quality of life survey of general surgical residents following implementation of the new work-hour restrictions. (United States)

    Hamadani, Fadi T; Deckelbaum, Dan; Sauve, Alexandre; Khwaja, Kosar; Razek, Tarek; Fata, Paola


    The implementation of work hour restrictions across North America have resulted in decreased levels of self injury and medical errors for Residents. An arbitration ruling in Quebec has led to further curtailment of work hours beyond that proposed by the ACGME. This may threaten Resident quality of life and in turn decrease the educational quality of surgical residency training. We administered a quality of life questionnaire with an integrated education quality assessment tool to all General Surgery residents training at McGill 6 months after the work hour restrictions. Across several strata respondents reveal a decreased sense of educational quality and quality of life. The arbitration argued that work- hour restrictions would be necessary to improve quality of life for trainees and hence improve patient safety. Results from this study demonstrate the exact opposite in a large majority of respondents, who report a poorer quality of life and a self-reported inability on their part to provide continuous and safe patient care.

  16. A serious game skills competition increases voluntary usage and proficiency of a virtual reality laparoscopic simulator during first-year surgical residents' simulation curriculum. (United States)

    El-Beheiry, Mostafa; McCreery, Greig; Schlachta, Christopher M


    The objective of this study was to assess the effect of a serious game skills competition on voluntary usage of a laparoscopic simulator among first-year surgical residents' standard simulation curriculum. With research ethics board approval, informed consent was obtained from first-year surgical residents enrolled in an introductory surgical simulation curriculum. The class of 2013 served as a control cohort following the standard curriculum which mandates completion of six laparoscopic simulator skill tasks. For the 2014 competition cohort, the only change introduced was the biweekly and monthly posting of a leader board of the top three and ten fastest peg transfer times. Entry surveys were administered assessing attitudes towards simulation-based training and competition. Cohorts were observed for 5 months. There were 24 and 25 residents in the control and competition cohorts, respectively. The competition cohort overwhelmingly (76 %) stated that they were not motivated to deliberate practice by competition. Median total simulator usage time was 132 min (IQR = 214) in the competition cohort compared to 89 (IQR = 170) in the control cohort. The competition cohort completed their course requirements significantly earlier than the control cohort (χ (2) = 6.5, p = 0.01). There was a significantly greater proportion of residents continuing to use the simulator voluntarily after completing their course requirements in the competition cohort (44 vs. 4 %; p = 0.002). Residents in the competition cohort were significantly faster at peg transfer (194 ± 66 vs. 233 ± 53 s, 95 % CI of difference = 4-74 s; p = 0.03) and significantly decreased their completion time by 33 ± 54 s (95 % CI 10-56 s; paired t test, p = 0.007). A simple serious games skills competition increased voluntary usage and performance on a laparoscopic simulator, despite a majority of participants reporting they were not motivated by competition.

    Pandya J


    Full Text Available Background: Postgraduate specialities require a combination of knowledge and clinical skills. The internship year is less structured. Clinical and practical skills that are picked up during training are not well regulated and the impact is not assessed. In this study, we assessed knowledge and skills using objective structured clinical examination (OSCE. Aim: To evaluate the clinical skills of new first-year surgical residents using orientation programme and OSCE as a tool for assessment. Settings and Design: Observational study. Materials and Methods: Twenty new first-year surgical residents (10 each in 2008 and 2009 participated in a detailed structured orientation programme conducted over a period of 7 days. Clinically important topics and skills expected at this level (e.g., suturing, wound care etc. were covered. The programme was preceded by an OSCE to test pre-programme knowledge (the "pre-test". The questions were validated by senior department staff. A post-programme OSCE (the "post-test" helped to evaluate the change in clinical skill level brought about by the orientation programme. Statistical Analysis: Wilcoxson matched-pairs signed-ranks test. Results: Passing performance was achieved by all participants in both pre- and post-tests. Following the orientation programme, significant improvement was seen in tasks testing the psychomotor and cognitive domains. (P = 0.0001 and P = 0.0401, respectively. Overall reliability of the OSCE was found to be 0.7026 (Cronbach′s coefficient alpha. Conclusions: This study highlighted the lacunae in current internship training, especially for skill-based tasks. There is a need for universal inclusion of structured orientation programmes in the training of first-year residents. OSCE is a reliable, valid and effective method for the assessment of clinical skills.

  19. A novel method of teaching surgical techniques to residents--computerized enhanced visual learning (CEVL) with simulation to certify mastery of training: a model using newborn clamp circumcision. (United States)

    Smith, Angela; Maizels, Max; Korets, Ruslan; Wiener, John S; Stiener, Michael; Liu, Dennis B; Sutherland, Richard W


    To assess the learning process of combining a web-based video of a simulated surgical procedure with a step-by-step checklist of the same procedure in achieving competency of the simulated technique, in this case a newborn clamp circumcision. Fundamental to this particular learning process is immediate mentor step-by-step feedback which specifically follows the procedure's step-by-step checklist. Pediatric residents naïve to newborn circumcision were enrolled (n = 7). A circumcision simulator, instruments, and web access to the learning module were provided. Residents trained independently and then performed two simulations with the mentor. The first simulation was completed with formative scored feedback. The learner then performed a second scored simulation. All learners showed improvement between the first and second simulation (mean 85.3-97.4). All residents achieved competency (96/100 or greater) by the second simulation. On post-procedure surveys, learners demonstrated increased comfort and reduced apprehension in performing the procedure. Combining a web-accessible video of a procedure, a checklist, and a simulator followed by a single mentor session with immediate formative feedback which follows the steps of the checklist is a useful method to teach the simulation technique of circumcision. We plan to study if this paradigm is transferable to clinical circumcision. Copyright © 2013 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.

  20. Excised Abdominoplasty Material as a Systematic Plastic Surgical Training Model

    M. Erol Demirseren


    Full Text Available Achieving a level of technical skill and confidence in surgical operations is the main goal of plastic surgical training. Operating rooms were accepted as the practical teaching venues of the traditional apprenticeship model. However, increased patient population, time, and ethical and legal considerations made preoperation room practical work a must for plastic surgical training. There are several plastic surgical teaching models and simulators which are very useful in preoperation room practical training and the evaluation of plastic surgery residents. The full thickness skin with its vascular network excised in abdominoplasty procedures is an easily obtainable real human tissue which could be used as a training model in plastic surgery.

  1. Head-camera video recordings of trauma core competency procedures can evaluate surgical resident's technical performance as well as colocated evaluators. (United States)

    Mackenzie, Colin F; Pasley, Jason; Garofalo, Evan; Shackelford, Stacy; Chen, Hegang; Longinaker, Nyaradzo; Granite, Guinevere; Pugh, Kristy; Hagegeorge, George; Tisherman, Samuel A


    Unbiased evaluation of trauma core competency procedures is necessary to determine if residency and predeployment training courses are useful. We tested whether a previously validated individual procedure score (IPS) for individual procedure vascular exposure and fasciotomy (FAS) performance skills could discriminate training status by comparing IPS of evaluators colocated with surgeons to blind video evaluations. Performance of axillary artery (AA), brachial artery (BA), and femoral artery (FA) vascular exposures and lower extremity FAS on fresh cadavers by 40 PGY-2 to PGY-6 residents was video-recorded from head-mounted cameras. Two colocated trained evaluators assessed IPS before and after training. One surgeon in each pretraining tertile of IPS for each procedure was randomly identified for blind video review. The same 12 surgeons were video-recorded repeating the procedures less than 4 weeks after training. Five evaluators independently reviewed all 96 randomly arranged deidentified videos. Inter-rater reliability/consistency, intraclass correlation coefficients were compared by colocated versus video review of IPS, and errors. Study methodology and bias were judged by Medical Education Research Study Quality Instrument and the Quality Assessment of Diagnostic Accuracy Studies criteria. There were no differences (p ≥ 0.5) in IPS for AA, FA, FAS, whether evaluators were colocated or reviewed video recordings. Evaluator consistency was 0.29 (BA) - 0.77 (FA). Video and colocated evaluators were in total agreement (p = 1.0) for error recognition. Intraclass correlation coefficient was 0.73 to 0.92, dependent on procedure. Correlations video versus colocated evaluations were 0.5 to 0.9. Except for BA, blinded video evaluators discriminated (p competency. Prognostic study, level II.

  3. Halstedian technique revisited. Innovations in teaching surgical skills. (United States)

    Barnes, R W; Lang, N P; Whiteside, M F


    This paper reviews the laboratory models used to teach fundamental surgical skills in our general surgery residency. The laboratory modules allow supervision and self-instruction, practice, and videotape monitoring of the following techniques: skin incision, suturing, knot tying, hemostasis, vascular anastomosis, and intestinal anastomosis. Pigs' feet simulate human skin for exercises in skin incision, lesion excision, suturing, and basic plastic surgical techniques. Latex tubing and penrose drains allow experience in suturing, knot tying, and hemostasis. Polytetrafluoroethylene vascular prostheses permit quantification of the precision of needle passage and suturing by measurement of leakage of water through a vascular anastomosis. Reconstituted, lyophilized, irradiated bovine arteries and ileum provide models of biologic tissue for creating handsewn vascular anastomoses and sutured or stapled gastrointestinal anastomoses. A headlamp videocamera allows unobstructive recording of the resident's technical performance and provides subsequent visual feedback for self-improvement when compared to reference instructional videotapes. We feel that these innovations may enhance surgical dexterity of residents without the need for animal sacrifice. Our goal is to foreshorten the learning curve for basic surgical skills and improve performance in the clinical operating room.

  4. Moist wound healing compared with standard care of treatment of primary closed vascular surgical wounds: a prospective randomized controlled study

    DEFF Research Database (Denmark)

    Vogt, Katja C; Uhlyarik, M; Schroeder, Torben V


    This study was a randomized-controlled trial comparing the standard type of dry dressing, Mepore, with moist wound healing, using a hydrofiber dressing, Aquacel, in primary closed wounds after vascular surgery. The endpoints were patient comfort, cost-effectiveness, infections, wound complications....... No difference in the infection rate (13% vs. 11%, p=0.73), length of hospital stay, or wound complications was noted between the two groups. We conclude that although the Aquacel dressing needed significantly fewer changes than the conventional dressing, this did not influence the patient comfort. Moreover...

  6. [Long-term results of peripheral vascular injuries in patients' limbs following reconstructive surgical procedures and influence on the quality of life]. (United States)

    Deja, Włodzimierz; Wieczorek, Dariusz; Deja, Agata; Lasek, Jerzy; Kawecka, Aleksandra; Marks, Wojciech


    Major vascular injuries in extremities are rare and constitute problems for surgeons and their sequelae strongly influence remote future of the patients. The aim of study is to evaluate surgical treatment of vascular injuries in extremities and some aspects of quality of life. Since 1983 until 2002 sixty four patients with vascular limbs injuries were treated in the department. Remote evaluation has been performed in 33 persons. Severity of limb injuries was measured by Mangled Extremity Severity Score (MESS). In 20 patients (60.6%) very good and good recent results were obtained, satisfactory in 24.2% and bad results in 15.2% persons. Evaluation of functional status has been made by means of locomotion test and Jebsen-Taylor's test, social approval questionnaire, depression Beck's scale, the scale of hypochondria and by an original questionnaire to evaluate the quality of life. As considerable interdependence has been found between the functional status and the following factors: injury severity expressed in MESS (p < 0.01), clinic reception procedure (p < 0.001), ischemia time (p < 0.01), coincidence of other injuries (fractures and dislocations, muscle, tendon and nerve lesions) (p < 0.01), limb amputation (p < 0.01). Hand function significantly influences the quality of life. Patients who were in shock after trauma in the remote assessment showed susceptibility to the lowered mood and depression (p < 0.05). Quality of life is strongly connected with the features of personality, correlating mainly with the mood and tendencies of concentration upon somatic symptoms. Function of the hand influences strongly the quality of life. Amputated patients may in spite of their crippling limitations are able to adapt to everyday life.

  7. Determining the Learning Curve of Transcutaneous Laryngeal Ultrasound in Vocal Cord Assessment by CUSUM Analysis of Eight Surgical Residents: When to Abandon Laryngoscopy. (United States)

    Wong, Kai-Pun; Lang, Brian Hung-Hin; Lam, Shi; Au, Kin-Pan; Chan, Diane Toi-yin; Kotewall, Nicholas Clarence


    Transcutaneous laryngeal ultrasonography (TLUSG) is a promising alternative to laryngoscopy in vocal cords (VCs) assessment which might be challenging in the beginning. However, it remains unclear when an assessor can provide proficient TLUSG enough to abandon direct laryngoscopy . Eight surgical residents (SRs) without prior USG experience were recruited to determine the learning curve. After a standardized training program, SRs would perform 80 consecutive peri-operative VCs assessment using TLUSG. Performances of SRs were quantitatively evaluated by a composite performance score (lower score representing better performance) which comprised total examination time (in seconds), VCs visualization, and assessment accuracy. Cumulative sum (CUSUM) chart was then used to evaluate learning curve. Diagnostic accuracy and demographic data between every twentieth TLUSG were compared. 640 TLUSG examinations had been performed by 8 residents. 95.1% of VCs could be assessed by SRs. The CUSUM curve showed a rising pattern (learning phase) until 7th TLUSG and then flattened. The curve declined continuously after 42nd TLUSG (after reaching a plateau). Rates of assessable VCs were comparable in every twentieth cases performed. It took a longer time to complete TLUSG in 1st-20th than 21st-40th examinations. (45 vs. 32s, p = 0.001). Although statistically not significant, proportion of false-negative results was higher in 21st-40th (2.5%) than 1(st)-20th (0.6%), 41(st)-60th (0.7%), and 61(st)-80th (0.7%) TLUSG performed. After a short formal training, surgeons could master skill in TLUSG after seven examination and assess vocal cord function consistently and accurately after 40 TLUSG.

  8. Vascular rings. (United States)

    Backer, Carl L; Mongé, Michael C; Popescu, Andrada R; Eltayeb, Osama M; Rastatter, Jeffrey C; Rigsby, Cynthia K


    The term vascular ring refers to congenital vascular anomalies of the aortic arch system that compress the esophagus and trachea, causing symptoms related to those two structures. The most common vascular rings are double aortic arch and right aortic arch with left ligamentum. Pulmonary artery sling is rare and these patients need to be carefully evaluated for frequently associated tracheal stenosis. Another cause of tracheal compression occurring only in infants is the innominate artery compression syndrome. In the current era, the diagnosis of a vascular ring is best established by CT imaging that can accurately delineate the anatomy of the vascular ring and associated tracheal pathology. For patients with a right aortic arch there recently has been an increased recognition of a structure called a Kommerell diverticulum which may require resection and transfer of the left subclavian artery to the left carotid artery. A very rare vascular ring is the circumflex aorta that is now treated with the aortic uncrossing operation. Patients with vascular rings should all have an echocardiogram because of the incidence of associated congenital heart disease. We also recommend bronchoscopy to assess for additional tracheal pathology and provide an assessment of the degree of tracheomalacia and bronchomalacia. The outcomes of surgical intervention are excellent and most patients have complete resolution of symptoms over a period of time. Copyright © 2016 Elsevier Inc. All rights reserved.

  10. American diagnostic radiology residency and fellowship programmes. (United States)

    Rumack, Carol Masters


    American Diagnostic Radiology Residency and Fellowship programmes are Graduate Medical Education programmes in the United States (US) equivalent to the Postgraduate Medical Education programmes in Singapore. Accreditation Council for Graduate Medical Education (ACGME) accredited diagnostic radiology residency programmes require 5 years total with Post Graduate Year (PGY) 1 year internship in a clinical specialty, e.g. Internal Medicine following medical school. PGY Years 2 to 5 are the core years which must include Radiology Physics, Radiation Biology and rotations in 9 required subspecialty rotations: Abdominal, Breast, Cardiothoracic, Musculoskeletal, Neuroradiology, Nuclear and Paediatric Radiology, Obstetric & Vascular Ultrasound and Vascular Interventional Radiology. A core curriculum of lectures must be organised by the required 9 core subspecialty faculty. All residents (PGY 2 to 4) take a yearly American College of Radiology Diagnostic In-Training Examination based on national benchmarks of medical knowledge in each subspecialty. Because the American Board of Radiology (ABR) examinations are changing, until 2012, residents have to take 3 ABR examinations: (i) ABR physics examination in the PGY 2 to 3 years, (ii) a written examination at the start of the PGY 5 year and (iii) an oral exam at the end of the PGY 5 year. Beginning in 2013, there will be only 2 examinations: (i) the physics and written examinations after PGY 4 will become a combined core radiology examination. Beginning in 2015, the final certifying examination will be given 15 months after the completion of residency. After residency, ACGME fellowships in PGY 6 are all one-year optional programmes which focus on only one subspecialty discipline. There are 4 ACGME accredited fellowships which have a Board Certifi cation Examination: Neuroradiology, Nuclear, Paediatric and Vascular Interventional Radiology. Some ACGME fellowships do not have a certifying examination: Abdominal, Endovascular

  11. Branding of vascular surgery. (United States)

    Perler, Bruce A


    The Society for Vascular Surgery surveyed primary care physicians (PCPs) to understand how PCPs make referral decisions for their patients with peripheral vascular disease. Responses were received from 250 PCPs in 44 states. More than 80% of the respondents characterized their experiences with vascular surgeons as positive or very positive. PCPs perceive that vascular surgeons perform "invasive" procedures and refer patients with the most severe vascular disease to vascular surgeons but were more than twice as likely to refer patients to cardiologists, believing they are better able to perform minimally invasive procedures. Nevertheless, PCPs are receptive to the notion of increasing referrals to vascular surgeons. A successful branding campaign will require considerable education of referring physicians about the totality of traditional vascular and endovascular care increasingly provided by the contemporary vascular surgical practice and will be most effective at the local grassroots level.

    Gómez Díaz, Carlos Javier; Luna Aufroy, Alexis; Rebasa Cladera, Pere; Serra Pla, Sheila; Jurado Ruiz, Cristina; Mora López, Laura; Serra Aracil, Xavier; Navarro Soto, Salvador


    The surgical electronic logbook (surgical e-logbook) aims to: simplify registration of the training activities of surgical residents, and to obtain reliable and detailed reports about these activities for resident evaluation. The surgical e-logbook is a unique and shared database. Residents prospectively record their activities in 3 areas: surgical, scientific and teaching. We can access activity reports that are constantly updated. Study period using the surgical e-logbook: Between June 2011 and May 2013. Number of surgeries reported: 4,255. Number of surgical procedures reported: 11,907. Number of surgeries per resident per year reported: 250. Number of surgical procedures per resident per year reported: 700. Surgical activity as a primary surgeon during the first year of residency is primarily in emergency surgery (68,01%) and by laparotomy (97,73%), while during the fifth year of residency 51,27% is performed in elective surgery and laparoscopy is used in 23,10% of cases. During this period, residents participated in a total of 11 scientific publications, 75 conference presentations and 69 continuing education activities. The surgical e-logbook is a useful tool that simplifies the recording and analysis of data about surgical and scientific activities of the residents. It is a step forward in the evaluation of the training of surgical residents, however, is only an intermediate step towards the development of a larger Spanish registry. Copyright © 2014 AEC.

    康骅; 张钰鹏; 王亚军; 陈丽芬


    Objective To investigate clinical competence assessment in the graduation examination for surgical professional degree postgraduates and surgical residents in Beijing. Methods Data of clinical competence assessment of graduation examination for surgical postgraduates from Capital Medical University (CMU) and residents from Beijing surgical residency training programs in 2013 were summarized and ana-lyzed. SPSS 11.5 software was used to do t test and chi square test to the corresponding data line. Results There were 118 surgical postgraduates in clinical medicine from CMU and 274 residents from Beijing surgi-cal residency training programs, who attended final clinical competence assessment. There were significant differences between the postgraduate and resident clinical competence assessment system. The differences included their organization in charge of examination and the contents of assessment system. The assessment system of clinical competence for the surgical postgraduates did not involved communication skills, reading and analysis of laboratory tests and imaging investigation. The score of case analysis in the postgraduate group was higher than that in the resident group [(84.6±1.1) vs. (82.2±10.2), P=0.039], however the score of surgical skill assessment in postgraduate group was significantly lower than that of the resident group [(78.2 ±14.0) vs. (90.5 ±6.3), P=0.000]. In addition, the rate in the score being higher or equal to 70 of case note, case analysis and surgical skill assessment between postgraduates and residents was significantly different (P<0.05). Conclusion Clinical competence assessment system for the surgical postgraduates should be adapted to their training goal. In addition to the process assessment, the objective structured clinical skills examination (OSCE) can be as a reasonable postgraduate graduation examination mode.%目的:探讨外科专业学位硕士研究生结业临床技能考核方案和

  18. In Vitro Generation of Vascular Wall-Resident Multipotent Stem Cells of Mesenchymal Nature from Murine Induced Pluripotent Stem Cells

    Directory of Open Access Journals (Sweden)

    Jennifer Steens


    Full Text Available The vascular wall (VW serves as a niche for mesenchymal stem cells (MSCs. In general, tissue-specific stem cells differentiate mainly to the tissue type from which they derive, indicating that there is a certain code or priming within the cells as determined by the tissue of origin. Here we report the in vitro generation of VW-typical MSCs from induced pluripotent stem cells (iPSCs, based on a VW-MSC-specific gene code. Using a lentiviral vector expressing the so-called Yamanaka factors, we reprogrammed tail dermal fibroblasts from transgenic mice containing the GFP gene integrated into the Nestin-locus (NEST-iPSCs to facilitate lineage tracing after subsequent MSC differentiation. A lentiviral vector expressing a small set of recently identified human VW-MSC-specific HOX genes then induced MSC differentiation. This direct programming approach successfully mediated the generation of VW-typical MSCs with classical MSC characteristics, both in vitro and in vivo.

  19. Perceptions of society for vascular surgery members and surgery department chairs of the integrated 0 + 5 vascular surgery training paradigm. (United States)

    Kiguchi, Misaki; Leake, Andrew; Switzer, Galen; Mitchell, Erica; Makaroun, Michel; Chaer, Rabih A


    As the first generation of integrated (0 + 5) vascular surgery (VS) residents enter the job market, this survey sought to understand how the surgical community perceives this training paradigm. An anonymous online survey was e-mailed to surgery chairpersons (n = 193) and Society for Vascular Surgery (SVS) members (n = 2193) in the United States/Canada with 26% (n = 38) and 14% (n = 309) response rates, respectively. Respondents were asked about their practice background, residency program, hiring patterns, and perceptions of the 0 + 5 training. Response rates were 26% (n = 38) and 14% (n = 309) for surgery chairpersons and SVS members, respectively. SVS respondents were from academic (62%) and private (38%) practices and included staff surgeons (62%), program directors (15%), and division chiefs (22%). Only 33% had a 0 + 5 program, and 57% had a VS fellowship. Overall, 94% were likely to hire a new vascular surgeon in the next 5 years. In some categories, SVS respondents believed 0 + 5 residents would be less prepared than 5 + 2 residents. Only 32% thought that 0 + 5 residents have the same level of surgical maturity, and 36% thought that they have the same level of open operative skills as 5 + 2 trainees. Another 34% thought 0 + 5 residents will need additional fellowship training in open surgery. However, there was also a general perception from SVS respondents that 0 + 5 residents would be prepared for clinical practice (67%) and would have equal endovascular skills to 5 + 2 trainees (92%). The chairpersons had similar perceptions as SVS members. Both SVS members (88%) and chairpersons (86%) would consider interviewing a 0 + 5 graduate for faculty position; 83% and 72%, respectively, would consider hiring. Moreover, 93% of SVS respondents who currently have a 0 + 5 program and 86% of SVS respondents who do not would consider hiring a 0 + 5 graduate. Both SVS members (62%) and chairpersons (50%) believed the 0 + 5 paradigm is essential for the advancement of VS

  20. A novel tumor-promoting function residing in the 5' non-coding region of vascular endothelial growth factor mRNA.

    Directory of Open Access Journals (Sweden)

    Kiyoshi Masuda


    Full Text Available BACKGROUND: Vascular endothelial growth factor-A (VEGF is one of the key regulators of tumor development, hence it is considered to be an important therapeutic target for cancer treatment. However, clinical trials have suggested that anti-VEGF monotherapy was less effective than standard chemotherapy. On the basis of the evidence, we hypothesized that vegf mRNA may have unrecognized function(s in cancer cells. METHODS AND FINDINGS: Knockdown of VEGF with vegf-targeting small-interfering (si RNAs increased susceptibility of human colon cancer cell line (HCT116 to apoptosis caused with 5-fluorouracil, etoposide, or doxorubicin. Recombinant human VEGF165 did not completely inhibit this apoptosis. Conversely, overexpression of VEGF165 increased resistance to anti-cancer drug-induced apoptosis, while an anti-VEGF165-neutralizing antibody did not completely block the resistance. We prepared plasmids encoding full-length vegf mRNA with mutation of signal sequence, vegf mRNAs lacking untranslated regions (UTRs, or mutated 5'UTRs. Using these plasmids, we revealed that the 5'UTR of vegf mRNA possessed anti-apoptotic activity. The 5'UTR-mediated activity was not affected by a protein synthesis inhibitor, cycloheximide. We established HCT116 clones stably expressing either the vegf 5'UTR or the mutated 5'UTR. The clones expressing the 5'UTR, but not the mutated one, showed increased anchorage-independent growth in vitro and formed progressive tumors when implanted in athymic nude mice. Microarray and quantitative real-time PCR analyses indicated that the vegf 5'UTR-expressing tumors had up-regulated anti-apoptotic genes, multidrug-resistant genes, and growth-promoting genes, while pro-apoptotic genes were down-regulated. Notably, expression of signal transducers and activators of transcription 1 (STAT1 was markedly repressed in the 5'UTR-expressing tumors, resulting in down-regulation of a STAT1-responsive cluster of genes (43 genes. As a result, the

    Tanvi N. Nadkarni


    Conclusion: Our results suggest that the type of task and the applied statistical threshold influence LI and that the threshold effects on LI may be task-specific. Thus identifying critical functional regions and computing LIs should be conducted on an individual subject basis, using a continuum of threshold values with different tasks to provide the most accurate information for surgical planning to minimize post-operative language deficits.

    Between January 1988 and January 1994, 24 patients with heterologeous vascular bypasses were examined with suspected diagnosis of a perigraft reaction (PGR). All patients were subjected to ultrasound and CT. PGR ist defined as a sterile inflammation along the course of a vascular prosthesis. The typical clinical presentation is a fluctuating tumour with a localised painless swelling. In all cases liquid formations could be confirmed by diagnostic imaging procedures; signs of infection could be excluded. The synopsis of the clinical presentation, the time interval after implantation of the prosthetic material and the signs of sonography and CT can reliably exclude infection of the prosthesis and confirm the diagnosis of a PGR. (orig.) [Deutsch] Von 1/88 bis 1/94 wurden 24 Patienten nach Implantation eines kuenstlichen Blutleiters nach 1,5 bis 12,5 Monaten postoperativ unter dem Verdacht einer klinisch manifesten Perigraftreaktion sonographisch und computertomographisch untersucht. Definitionsgemaess handelt es sich bei der Perigraftreaktion um eine sterile Entzuendung entlang einer vaskulaeren Kunststoffprothese. Klinisch imponiert sie als ein fluktuierender Tumor mit einer lokalen, indolenten Schwellung entlang der Prothese. In allen untersuchten Faellen waren liquide Formationen entlang der kuenstlichen Blutleiter ohne Zeichen eines Protheseninfektes nachzuweisen. Unter Beruecksichtigung der Klinik, des zeitlichen Intervalls und der Korrelation der Bildgebung mit den Laborparametern sowie der Bakteriologie konnte ein Protheseninfekt, der immer noch eine hohe Morbiditaet und Mortalitaet besitzt, zuverlaessig ausgeschlossen werden.

  5. Are general surgery residents adequately prepared for hepatopancreatobiliary fellowships? A questionnaire-based study (United States)

    Osman, Houssam; Parikh, Janak; Patel, Shirali; Jeyarajah, D Rohan


    Background The present study was conducted to assess the preparedness of hepatopancreatobiliary (HPB) fellows upon entering fellowship, identify challenges encountered by HPB fellows during the initial part of their HPB training, and identify potential solutions to these challenges that can be applied during residency training. Methods A questionnaire was distributed to all HPB fellows in accredited HPB fellowship programmes in two consecutive academic years (n = 42). Reponses were then analysed. Results A total of 19 (45%) fellows responded. Prior to their fellowship, 10 (53%) were in surgical residency and the rest were in other surgical fellowships or surgical practice. Thirteen (68%) were graduates of university-based residency programmes. All fellows felt comfortable in performing basic laparoscopic procedures independently at the completion of residency and less comfortable in performing advanced laparoscopy. Eight (42%) fellows cited a combination of inadequate case volume and lack of autonomy during residency as the reasons for this lack of comfort. Thirteen (68%) identified inadequate preoperative workup and management as their biggest fear upon entering practice after general surgery training. A total of 17 (89%) fellows felt they were adequately prepared to enter HPB fellowship. Extra rotations in transplant, vascular or minimally invasive surgery were believed to be most helpful in preparing general surgery residents pursing HPB fellowships. Conclusions Overall, HPB fellows felt themselves to be adequately prepared for fellowship. Advanced laparoscopic procedures and the perioperative management of complex patients are two of the challenges facing HPB fellows. General surgery residents who plan to pursue an HPB fellowship may benefit from spending extra rotations on certain subspecialties. Focus on perioperative workup and management should be an integral part of residency and fellowship training. PMID:25387852

  6. Resident resistance. (United States)

    Price, J L; Cleary, B


    Clearly, faculty must work hard with residents to explore the nature of their resistance to a program's learning and growth opportunities. Initial steps to a deeper, more effective, and longer-lasting change process must be pursued. If resident resistance is mishandled or misunderstood, then learning and professional growth may be sidetracked and the purposes of residency training defeated. Listening to the whole person of the resident and avoiding the trap of getting caught up in merely responding to select resident behaviors that irritate us is critical. Every faculty member in the family practice residency program must recognize resistance as a form of defense that cannot immediately be torn down or taken away. Resident defenses have important purposes to play in stress reduction even if they are not always healthy. Residents, especially interns, use resistance to avoid a deeper and more truthful look at themselves as physicians. A family practice residency program that sees whole persons in their residents and that respects resident defenses will effectively manage the stress and disharmony inherent to the resistant resident.

  7. Does general surgery residency prepare surgeons for community practice in British Columbia? (United States)

    Hwang, Hamish


    Preparing surgeons for clinical practice is a challenging task for postgraduate training programs across Canada. The purpose of this study was to examine whether a single surgeon entering practice was adequately prepared by comparing the type and volume of surgical procedures experienced in the last 3 years of training with that in the first year of clinical practice. During the last 3 years of general surgery training, I logged all procedures. In practice, the Medical Services Plan (MSP) of British Columbia tracks all procedures. Using MSP remittance reports, I compiled the procedures performed in my first year of practice. I totaled the number of procedures and broke them down into categories (general, colorectal, laparoscopic, endoscopic, hepatobiliary, oncologic, pediatric, thoracic, vascular and other). I then compared residency training with community practice. I logged a total of 1170 procedures in the last 3 years of residency. Of these, 452 were performed during community rotations. The procedures during residency could be broken down as follows: 392 general, 18 colorectal, 242 laparoscopic, 103 endoscopic, 85 hepatobiliary, 142 oncologic, 1 pediatric, 78 thoracic, 92 vascular and 17 other. I performed a total of 1440 procedures in the first year of practice. In practice the break down was 398 general, 15 colorectal, 101 laparoscopic, 654 endoscopic, 2 hepatobiliary, 77 oncologic, 10 pediatric, 0 thoracic, 70 vascular and 113 other. On the whole, residency provided excellent preparation for clinical practice based on my experience. Areas of potential improvement included endoscopy, pediatric surgery and "other," which comprised mostly hand surgery.

    Nagengast, Eric S; Ramos, Margarita S; Sarma, Hiteswar; Deshpande, Gaurav; Hatcher, Kristin; Magee, William P; Campbell, Alex


    Surgical training is facing new obstacles. As advancements in medicine are made, surgeons are expected to know more and to be able to perform more procedures. In the western world, increasing restrictions on residency work hours are adding a new hurdle to surgical training. In low-resource settings, a low attending-to-resident ratio results in limited operative experience for residents. Advances in telemedicine may offer new methods for surgical training. In this article, the authors share their unique experience using live video broadcasting of surgery for educational purposes at a comprehensive cleft care center in Guwahati, India.

  10. Case-Logging Practices in Otolaryngology Residency Training: National Survey of Residents and Program Directors. (United States)

    Dermody, Sarah M; Gao, William; McGinn, Johnathan D; Malekzadeh, Sonya


    Objective (1) Evaluate the consistency and manner in which otolaryngology residents log surgical cases. (2) Assess the extent of instruction and guidance provided by program directors on case-logging practices. Study Design Cross-sectional national survey. Setting Accreditation Council for Graduate Medical Education otolaryngology residency programs in the United States. Subjects and Methods US otolaryngology residents, postgraduate year 2 through graduating chiefs as of July 2016, were recruited to respond to an anonymous questionnaire designed to characterize surgical case-logging practices. Program directors of US otolaryngology residency programs were recruited to respond to an anonymous questionnaire to elucidate how residents are instructed to log cases. Results A total of 272 residents and 53 program directors completed the survey, yielding response rates of 40.6% and 49.5%, respectively. Perceived accuracy of case logs is low among residents and program directors. Nearly 40% of residents purposely choose not to log certain cases, and 65.1% of residents underreport cases performed. More than 80% of program directors advise residents to log procedures performed outside the operating room, yet only 16% of residents consistently log such cases. Conclusion Variability in surgical case-logging behaviors and differences in provided instruction highlight the need for methods to improve consistency of logging practices. It is imperative to standardize practices across otolaryngology residency programs for case logs to serve as an accurate measure of surgical competency. This study provides a foundation for reform efforts within residency programs and for the Resident Case Log System.

  11. Comparison of surgical procedures for vascular and airway anastomoses that utilize a modified non-suture external cuff technique for experimental lung transplantation in rats. (United States)

    Mizobuchi, Teruaki; Sekine, Yasuo; Yasufuku, Kazuhiro; Fujisawa, Takehiko; Wilkes, David S


    Lung transplantation in rats is technically difficult and results may vary. The non-suture cuff technique (non-suture [NS]), which involves using a cuff for anastomoses of vessels and airways, is commonly utilized to perform transplant procedures. However, the standard bronchial cuff may occlude the lumen, resulting in diminished graft survival. In contrast, the non-suture cuff technique for vascular anastomoses with bronchial suturing (bronchial suture [BS]), although more technically difficult, is known to have prolonged bronchial patency. We developed a "modified" NS technique that uses a larger and longer cuff for anastomoses and compared the efficacy of this procedure to the BS technique for lung transplantation. The BS procedure was performed in 146 transplant procedures. The modified NS procedure, which uses a larger cuff than the standard NS procedure, was performed in 113 procedures. Although total ischemic times were comparable, the total operation time in the NS group was significantly shorter than in the BS group (p technique is widely acknowledged to provide prolonged patency of bronchial anastomosis, graft survival in the NS group was observed up 17 months post-transplant. These data show that the NS technique, which is less technically difficult, results in shorter operative times compared with the BS procedure, and results in durable anastomoses of lung grafts.

  13. Vascular regeneration in a basal chordate is due to the presence of immobile, bi-functional cells.

    Directory of Open Access Journals (Sweden)

    Brian P Braden

    Full Text Available The source of tissue turnover during homeostasis or following injury is usually due to proliferation of a small number of resident, lineage-restricted stem cells that have the ability to amplify and differentiate into mature cell types. We are studying vascular regeneration in a chordate model organism, Botryllus schlosseri, and have previously found that following surgical ablation of the extracorporeal vasculature, new tissue will regenerate in a VEGF-dependent process within 48 hrs. Here we use a novel vascular cell lineage tracing methodology to assess regeneration in parabiosed individuals and demonstrate that the source of regenerated vasculature is due to the proliferation of pre-existing vascular resident cells and not a mobile progenitor. We also show that these cells are bi-potential, and can reversibly adopt two fates, that of the newly forming vessels or the differentiated vascular tissue at the terminus of the vasculature, known as ampullae. In addition, we show that pre-existing vascular resident cells differentially express progenitor and differentiated cell markers including the Botryllus homologs of CD133, VEGFR-2, and Cadherin during the regenerative process.

  14. Bacterial wall products induce downregulation of vascular endothelial growth factor receptors on endothelial cells via a CD14-dependent mechanism: implications for surgical wound healing.

    LENUS (Irish Health Repository)

    Power, C


    INTRODUCTION: Vascular endothelial growth factor (VEGF) is a potent mitogenic cytokine which has been identified as the principal polypeptide growth factor influencing endothelial cell (EC) migration and proliferation. Ordered progression of these two processes is an absolute prerequisite for initiating and maintaining the proliferative phase of wound healing. The response of ECs to circulating VEGF is determined by, and directly proportional to, the functional expression of VEGF receptors (KDR\\/Flt-1) on the EC surface membrane. Systemic sepsis and wound contamination due to bacterial infection are associated with significant retardation of the proliferative phase of wound repair. The effects of the Gram-negative bacterial wall components lipopolysaccharide (LPS) and bacterial lipoprotein (BLP) on VEGF receptor function and expression are unknown and may represent an important biological mechanism predisposing to delayed wound healing in the presence of localized or systemic sepsis. MATERIALS AND METHODS: We designed a series of in vitro experiments investigating this phenomenon and its potential implications for infective wound repair. VEGF receptor density on ECs in the presence of LPS and BLP was assessed using flow cytometry. These parameters were assessed in hypoxic conditions as well as in normoxia. The contribution of CD14 was evaluated using recombinant human (rh) CD14. EC proliferation in response to VEGF was quantified in the presence and absence of LPS and BLP. RESULTS: Flow cytometric analysis revealed that LPS and BLP have profoundly repressive effects on VEGF receptor density in normoxic and, more pertinently, hypoxic conditions. The observed downregulation of constitutive and inducible VEGF receptor expression on ECs was not due to any directly cytotoxic effect of LPS and BLP on ECs, as measured by cell viability and apoptosis assays. We identified a pivotal role for soluble\\/serum CD14, a highly specific bacterial wall product receptor, in

  18. Regional intensity of vascular care and lower extremity amputation rates (United States)

    Goodney, Philip P.; Holman, Kerianne; Henke, Peter K.; Travis, Lori L.; Dimick, Justin B.; Stukel, Therese A.; Fisher, Elliott. S.; Birkmeyer, John D.


    Objective To examine the relationship between the intensity of vascular care and population-based rate of major lower extremity amputation (above-or below-knee) from vascular disease. Background Because patient-level differences do not fully explain the variation in amputation rate across the United States, we hypothesized that variation in intensity of vascular care may also affect regional rates of amputation. Methods Intensity of vascular care was defined as the proportion of Medicare patients who underwent any vascular procedure in the year prior to amputation, calculated at the regional level (2003–2006), using the 306 hospital referral regions in the Dartmouth Atlas of Healthcare. We examined relationship between intensity of vascular care and major amputation rate, at the regional level, between 2007–2009. Results Amputation rates varied widely by region, from 1 to 27 per 10,000 Medicare patients. Compared to regions in the lowest quintile of amputation rate, patients in the highest quintile were commonly African American (50% versus 13%) and diabetic (38% versus 31%). Intensity of vascular care also varied across regions: fewer than 35% of patients underwent revascularization in the lowest quintile of intensity, while nearly 60% of patients underwent revascularization in the highest quintile. Overall, there was an inverse correlation between intensity of vascular care and amputation rate ranging from R= −0.36 for outpatient diagnostic and therapeutic procedures, to R= −0.87 for inpatient surgical revascularizations. In analyses adjusting for patient characteristics and socioeconomic status, patients in high vascular care regions were significantly less likely to undergo amputation without an antecedent attempt at revascularization (OR 0.37, 95% CI 0.34–0.37, pamputation varies, and regions with the most intensive vascular care have the lowest amputation rate, although the observational nature of associations do not impart causality.

  19. Vascular compression syndromes. (United States)

    Czihal, Michael; Banafsche, Ramin; Hoffmann, Ulrich; Koeppel, Thomas


    Dealing with vascular compression syndromes is one of the most challenging tasks in Vascular Medicine practice. This heterogeneous group of disorders is characterised by external compression of primarily healthy arteries and/or veins as well as accompanying nerval structures, carrying the risk of subsequent structural vessel wall and nerve damage. Vascular compression syndromes may severely impair health-related quality of life in affected individuals who are typically young and otherwise healthy. The diagnostic approach has not been standardised for any of the vascular compression syndromes. Moreover, some degree of positional external compression of blood vessels such as the subclavian and popliteal vessels or the celiac trunk can be found in a significant proportion of healthy individuals. This implies important difficulties in differentiating physiological from pathological findings of clinical examination and diagnostic imaging with provocative manoeuvres. The level of evidence on which treatment decisions regarding surgical decompression with or without revascularisation can be relied on is generally poor, mostly coming from retrospective single centre studies. Proper patient selection is critical in order to avoid overtreatment in patients without a clear association between vascular compression and clinical symptoms. With a focus on the thoracic outlet-syndrome, the median arcuate ligament syndrome and the popliteal entrapment syndrome, the present article gives a selective literature review on compression syndromes from an interdisciplinary vascular point of view.

    Medical resident education in the United States has been a matter of national priority for decades, exemplified initially through the Liaison Committee for Graduate Medical Education and then superseded by the Accreditation Council for Graduate Medical Education. A recent Special Report in the New England Journal of Medicine, however, has described resident educational programs to date as prescriptive, noting an absence of innovation in education. Current aims of contemporary medical resident education are thus being directed at ensuring quality in learning as well as in patient care. Achievement and work-motivation theories attempt to explain people's choice, performance, and persistence in tasks. Expectancy Theory as one such theory was reviewed in detail, appearing particularly applicable to surgical residency training. Correlations between Expectancy Theory as a work-motivation theory and residency education were explored. Understanding achievement and work-motivation theories affords an opportunity to gain insight into resident motivation in training. The application of Expectancy Theory in particular provides an innovative perspective into residency education. Afforded are opportunities to promote the development of programmatic methods facilitating surgical resident motivation in education.

  3. The effects of local nitroglycerin on the surgical delay procedure in prefabricated flaps by vascular implant in rats Efeitos da nitroglicerina tópica na autonomização de retalhos pré-fabricados por implante vascular em ratos

    Directory of Open Access Journals (Sweden)

    Jairo Zacchê de Sá


    Full Text Available PURPOSE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.OBJETIVO: Avaliar o efeito da nitroglicerina tópica sobre a área viável de um modelo de retalho pré-fabricado por implante vascular em ratos e analisar o mecanismo de autonomização cirúrgica aplicada a retalhos pré-fabricados.

  7. Defining excellence in vascular neurosurgery. (United States)

    Sanai, Nader; Spetzler, Robert F


    Success as a vascular neurosurgeon almost always begins with passion, an inherent love for the work that drives an insatiable desire for personal improvement. A personal definition of excellence in vascular neurosurgery includes several fundamental qualities: mastery of the basics, refinement of technique, advancement of technology, investigative study, advanced decision making, microsurgical innovation, a well-rounded surgical armamentarium, and a lifelong commitment to teaching. Ultimately, the reward for these efforts is the ability to influence generations to come, particularly as one follows the rising careers of former trainees, each redefining the term "excellence" in vascular neurosurgery.

  8. Permanent resident. (United States)

    Fisher, John F


    The training of physicians in the past century was based primarily on responsibility and the chain-of-command. Those with the bulk of that responsibility in the fields of pediatrics and internal medicine were residents. Residents trained the medical students and supervised them carefully in caring for patients. Most attending physicians supervised their teams at arm's length, primarily serving as teachers of the finer points of diagnosis and treatment during set periods of the day or week with a perfunctory signature on write-ups or progress notes. Residents endeavored to protect the attending physician from being heavily involved unless they were unsure about a clinical problem. Before contacting the attending physician, a more senior resident would be called. Responsibility was the ultimate teacher. The introduction of diagnosis-related groups by the federal government dramatically changed the health care delivery system, placing greater emphasis on attending physician visibility in the medical record, ultimately resulting in more attending physician involvement in day-to-day care of patients in academic institutions. Without specified content in attending notes, hospital revenues would decline. Although always in charge technically, attending physicians increasingly have assumed the role once dominated by the resident. Using biographical experiences of more than 40 years, the author acknowledges and praises the educational role of responsibility in his own training and laments its declining role in today's students and house staff.

  12. Fellowship trends of pathology residents. (United States)

    Lagwinski, Nikolaj; Hunt, Jennifer L


    Recent changes in pathology residency education have included a decrease in the program length (from 5 years to 4 years for combined anatomic and clinical pathology training) and a national mandate for programs to assess 6 general competencies of trainees. These have undoubtedly led to changes in program curricula and in residents' desires to seek fellowship training. This study was designed to gather information about what residents are seeking from fellowship training programs. This study used an online survey to assess attitudes of residents in training programs toward fellowship training. The survey instrument had 26 questions pertaining to fellowship choices, motivations for pursuing fellowships, expectations of the fellowships, and postresidency concerns. There were 213 respondents from a mix of program types and representing each postgraduate year. Most residents will seek at least 1 or 2 fellowships after residency training. The most popular first-choice fellowship was surgical pathology (26%), followed by cytopathology (16%), hematopathology (15%), gastrointestinal pathology (10%), dermatopathology (8%), and forensic pathology (5%). The most common reasons for pursuing fellowship training were to "increase marketability" (43%) or to "become an expert in a particular area" (33%). Most trainees got their information about fellowship training programs from Internet sources. Fellowship programs will benefit from an optimally designed Web site because residents seek information predominantly from the Internet. Residents seeking fellowships are particularly concerned with selecting programs that provide job connections, an increase in their marketability, and the opportunity to develop diagnostic expertise.

  14. [Financing and control of surgical training]. (United States)

    Schröder, W; Welcker, K


    The present analyses of different surgical training systems show that training of surgical residents significantly contributes to hospital costs. These are predominantly caused by prolonged operation times of residents with increased work load for other staff members in the operating room. In addition, the productivity of surgical residents is less compared to experienced surgeons. On the other hand, hospital managements save money by the lower standard wages paid to the residents. The amount of educational costs is difficult to determine because surgical training takes place as on the job training. Therefore, from an economic point of view, the two products patient care and surgical training are difficult to separate. There are no reliable cost analyses available for the German training system. At present surgical training is indirectly financed by the DRG (diagnosis-related groups) flat rates of the health insurance. Possible options of financing the surgical training are additional funding from the health department or redistribution with supplemental payment for those surgical departments which contribute significantly more to the residents' training. Statements of medical associations, health departments and health insurances demonstrate the difficulty to come to an agreement concerning the finances of the training system. Despite this controversial discussion it should be taken into consideration that there is no alternative to a high quality surgical training as this is the basis for an effective health system.

    An Internet application could collect information to satisfy documentation required by the Residency Review Committee. Beyond replacing a difficult and inefficient paper system, it would collect, process, and distribute information to administration, faculty, and residents. Descriptive study. An integrated residency of 18 services at a university teaching hospital with 4 affiliated institutions. Residency administrators, faculty, and residents. The application included a procedure recorder, resident evaluation of faculty and rotations, goals and objectives (stratified by service and resident level), and matching faculty evaluation of residents with these goals as competencies. Policies, schedules, research opportunities, clinical site information, and curriculum support were created. Degree of compliance with Residency Review Committee standards, number of deficiencies corrected, and quantity and quality of information available to administration, faculty, and residents. The Internet system increased resident compliance for faculty and rotation evaluations from 20% and 34%, respectively, to 100%, which was maintained for 22 months. These evaluations can be displayed individually, in summary grids, and as postgraduate year-specific averages. Faculty evaluations of residents can be reviewed throughout the system. The defined category report for procedures, which had deficiencies in the preceding 6 years, had none for the last 2 years. The Internet application provides Accreditation Council for Graduate Medical Education-validated operative logs to regulatory agencies. A Web-based system can satisfy requirements and provide processed data that are of better quality and more complete than our paper system. We are now able to use scarce time and personnel to nurture developing surgical residents instead of shuffling paper.

A recent Special Report in the New England Journal of Medicine, however, has described resident educational programs to date as prescriptive, noting an absence of innovation in education. Current aims of contemporary medical resident education are thus being directed at ensuring quality in learning as well as in patient care. Achievement and work-motivation theories attempt to explain people's choice, performance, and persistence in tasks. Expectancy Theory as one such theory was reviewed in detail, appearing particularly applicable to surgical residency training. Correlations between Expectancy Theory as a work-motivation theory and residency education were explored. Understanding achievement and work-motivation theories affords an opportunity to gain insight into resident motivation in training. The application of Expectancy Theory in particular provides an innovative perspective into residency education. Afforded are opportunities to promote the development of programmatic methods facilitating surgical resident motivation in education. Keywords: learning, education, achievement

  3. Does general surgery residency prepare surgeons for community practice in British Columbia? (United States)

    Hwang, Hamish


    Background Preparing surgeons for clinical practice is a challenging task for postgraduate training programs across Canada. The purpose of this study was to examine whether a single surgeon entering practice was adequately prepared by comparing the type and volume of surgical procedures experienced in the last 3 years of training with that in the first year of clinical practice. Methods During the last 3 years of general surgery training, I logged all procedures. In practice, the Medical Services Plan (MSP) of British Columbia tracks all procedures. Using MSP remittance reports, I compiled the procedures performed in my first year of practice. I totaled the number of procedures and broke them down into categories (general, colorectal, laparoscopic, endoscopic, hepatobiliary, oncologic, pediatric, thoracic, vascular and other). I then compared residency training with community practice. Results I logged a total of 1170 procedures in the last 3 years of residency. Of these, 452 were performed during community rotations. The procedures during residency could be broken down as follows: 392 general, 18 colorectal, 242 laparoscopic, 103 endoscopic, 85 hepatobiliary, 142 oncologic, 1 pediatric, 78 thoracic, 92 vascular and 17 other. I performed a total of 1440 procedures in the first year of practice. In practice the break down was 398 general, 15 colorectal, 101 laparoscopic, 654 endoscopic, 2 hepatobiliary, 77 oncologic, 10 pediatric, 0 thoracic, 70 vascular and 113 other. Conclusion On the whole, residency provided excellent preparation for clinical practice based on my experience. Areas of potential improvement included endoscopy, pediatric surgery and “other,” which comprised mostly hand surgery. PMID:19503663

  4. Cost and logistics of implementing a tissue-based American College of Surgeons/Association of Program Directors in Surgery surgical skills curriculum for general surgery residents of all clinical years. (United States)

    Henry, Brandon; Clark, Philip; Sudan, Ranjan


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

  5. [The future of vascular medicine]. (United States)

    Kroeger, K; Luther, B


    In the future vascular medicine will still have a great impact on health of people. It should be noted that the aging of the population does not lead to a dramatic increase in patient numbers, but will be associated with a changing spectrum of co-morbidities. In addition, vascular medical research has to include the intensive care special features of vascular patients, the involvement of vascular medicine in a holistic concept of fast-track surgery, a geriatric-oriented intensive monitoring and early geriatric rehabilitation. For the future acceptance of vascular medicine as a separate subject area under delimitation of cardiology and radiology is important. On the other hand, the subject is so complex and will become more complex in future specialisations that mixing of surgery and angiology is desirable, with the aim to preserve the vascular surgical knowledge and skills on par with the medical and interventional measures and further develop them. Only large, interdisciplinary guided vascular centres will be able to provide timely diagnosis and therapy, to deal with the growing multi-morbidity of the patient, to perform complex therapies even in an acute emergency and due to sufficient number of cases to present with well-trained and experienced teams. These requirements are mandatory to decrease patients' mortality step by step.

  6. Is surgical workforce diversity increasing? (United States)

    Andriole, Dorothy A; Jeffe, Donna B; Schechtman, Kenneth B


    We sought to determine the extent to which recent increases in levels of gender and racial diversity in the overall resident-physician workforce were evident among core-surgical specialty resident workforces. Chi-square tests for trend assessed the importance of changes from 1996 to 2004 in proportions of women and African Americans in the surgery-resident workforce. Surgery-resident trends were compared with overall resident workforce trends using two-tailed t-tests to compare regression slopes that quantified rates of change over time. Chi-square tests assessed differences between proportions of women and African Americans in the current overall board-certified workforce and their proportions in the surgery board-certified workforce. From 1996 to 2004, proportions of women increased in all seven surgical specialties studied. Compared with the overall trend toward increasing proportions of women in the resident workforce, the trend in one surgical specialty was larger (obstetrics/gynecology, p 0.05), and two were smaller (each p 0.05). Proportions of African Americans decreased in three specialties (each p workforce, except obstetrics/gynecology, remained lower than in the overall board-certified workforce (each p workforces have persisted since 1996 and will likely perpetuate ongoing surgery board-certified workforce disparities.

  7. Vascular anomalies: differential diagnosis and mimickers. (United States)

    Garzon, Maria C; Weitz, Nicole; Powell, Julie


    Vascular anomalies are very common in children and encompass a wide spectrum of diseases. Many vascular anomalies can be mistaken for infantile hemangioma (IH). In addition, there is a variety of rare disorders including benign and malignant tumors that may mimic IH and other types of vascular anomalies. Understanding the clinical features, natural history, and typical clinical course of different types of vascular anomalies is essential in order to make the correct diagnosis and guide management. Radiologic imaging plays an important role in establishing the diagnosis; and when the diagnosis remains in doubt, a biopsy performed by a surgical specialist with expertise may prove to be lifesaving.

  9. Vascular Reconstruction in Hepatic Malignancy. (United States)

    Berumen, Jennifer; Hemming, Alan


    With surgery for hepatic malignancy, there are poor options for chemotherapy; many patients are deemed unresectable because of vascular involvement or location of tumors. Over the past few decades, advances in surgical technique have allowed resection of these tumors with vascular reconstruction to achieve negative margins and improve chances for survival. This article reviews those reconstruction techniques and outcomes in detail, including in situ perfusion and ex vivo liver surgery, and provides a discussion of implications and operative planning for patients with hepatic malignancy in order to provide surgeons with better understanding of these complicated operations.

    Cevidanes, Lucia; Tucker, Scott; Styner, Martin; Kim, Hyungmin; Chapuis, Jonas; Reyes, Mauricio; Proffit, William; Turvey, Timothy; Jaskolka, Michael


    This paper discusses the development of methods for computer-aided jaw surgery. Computer-aided jaw surgery allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery (CAS) system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3D surface models from Cone-beam CT (CBCT), dynamic cephalometry, semi-automatic mirroring, interactive cutting of bone and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intra-operative guidance. The system provides further intra-operative assistance with the help of a computer display showing jaw positions and 3D positioning guides updated in real-time during the surgical procedure. The CAS system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training and assessing the difficulties of the surgical procedures prior to the surgery. CAS has the potential to make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

    Full Text Available AIM: To determine the knowledge and attitudes of non-psychiatry residents about electroconvulsive therapy (ECT and additionally to make a comparison between residents of medical sciences and surgical sciences. METHODS: The study consisted of 176 medical school graduates in their residency training (119 medical sciences, 57 surgical sciences at a university hospital. All subjects are asked to fill a questionnaire prepared by the authors. RESULTS: Among all, 58 of the medical sciences residents (48.7%, and 32 of the surgical sciences residents (56.1% had reported that they have never observed any ECT session. There was no statistically significant difference between the residents of the two groups in terms of theirs attitudes towards ECT (p>0.05. The residents of surgical sciences differed from the others only in their response to the question that sought answer whether they would agree to have any of their relatives to undergo ECT. They more often disagreed to this statement (p=0.02. CONCLUSIONS: The knowledge and attitudes of residents in medical, and surgical sciences about ECT seemed to be similar. Despite their significant amount of knowledge about ECT the residents showed similar attitudes towards it with the patients and their caregivers that were previously reported in the literature. Additionally, the results also suggest that current training in medical schools need a revision that would eventually improve attitudes of medical graduates towards ECT.

  16. Residents as Educators: A Modern Model. (United States)

    Kensinger, Clark D; McMaster, William G; Vella, Michael A; Sexton, Kevin W; Snyder, Rebecca A; Terhune, Kyla P


    Education during surgical residency has changed significantly. As part of the shifting landscape, the importance of an organized and structured curriculum has increased. However, establishing this is often difficult secondary to clinical demands and pressure both on faculty and residents. We present a peer-assisted learning model for academic institutions without professional non-clinical educations. The "resident as educator" (RAE) model empowers residents to be the organizers of the education curriculum. RAE is built on a culture of commitment to education, skill development and team building, allowing the upper level residents to develop and execute the curriculum. Several modules designed to address junior level residents and medical students' educational needs have been implemented, including (1) intern boot camp, (2) summer school, (3) technical skill sessions, (4) trauma orientation, (5) weekly teaching conferences, and (4) a fourth year medical student surgical preparation course. Promoting residents as educators leads to an overall benefit for the program by being cost-effective and time-efficient, while simultaneously promoting professional development of residents and a culture of education.

  17. Ongoing deficits in resident training for minimally invasive surgery. (United States)

    Park, Adrian; Witzke, Donald; Donnelly, Michael


    Patient preference has driven the adoption of minimally invasive surgery (MIS) techniques and altered surgical practice. MIS training in surgical residency programs must teach new skill sets with steep learning curves to enable residents to master key procedures. Because no nationally recognized MIS curriculum exists, this study asked experts in MIS which laparoscopic procedures should be taught and how many cases are required for competency. Expert recommendations were compared to the number of cases actually performed by residents (Residency Review Committee [RRC] data). A detailed survey was sent nationwide to all surgical residency programs (academic and private) known to offer training in MIS and/or have a leader in the field. The response rate was approximately 52%. RRC data were obtained from the resident statistics summary report for 1998-1999. Experts identified core procedures for MIS training and consistently voiced the opinion that to become competent, residents need to perform these procedures many more times than the RRC data indicate they currently do. At present, American surgical residency programs do not meet the suggested MIS case range or volume required for competency. Residency programs need to be restructured to incorporate sufficient exposure to core MIS procedures. More expert faculty must be recruited to train residents to meet the increasing demand for laparoscopy.

    Cervantes, Jorge


    Surgical education in Mexico basically follows the same model as in the United States, with a selection process resembling the matching program. There is a 4-year training period during which residents in their third year spend 4 months as the sole surgeon in a rural community. During the senior year they are entitled to an elective period in a place of their choosing. After completion of the 4 years, residents have to present a thesis and undergo an oral examination before getting a university diploma. They are then encouraged to pass the written and oral examination of the Mexican Board of Surgery before they are fully certified to enter practice in a public or private hospital.

  20. For Love, Not Money: The Financial Implications of Surgical Fellowship Training. (United States)

    Inclan, Paul M; Hyde, Adam S; Hulme, Michael; Carter, Jeffrey E


    Surgical residents cite increased income potential as a motivation for pursuing fellowship training, despite little evidence supporting this perception. Thus, our goal is to quantify the financial impact of surgical fellowship training on financial career value. By using Medical Group Management Association and Association of American Medical Colleges physician income data, and accounting for resident salary, student debt, a progressive tax structure, and forgone wages associated with prolonged training, we generated a net present value (NPV) for both generalist and subspecialist surgeons. By comparing generalist and subspecialist career values, we determined that cardiovascular (NPV = 698,931), pediatric (430,964), thoracic (239,189), bariatric (166,493), vascular (96,071), and transplant (46,669) fellowships improve career value. Alternatively, trauma (11,374), colorectal (44,622), surgical oncology (203,021), and breast surgery (326,465) fellowships all reduce career value. In orthopedic surgery, spine (505,198), trauma (123,250), hip and joint (60,372), and sport medicine (56,167) fellowships improve career value, whereas shoulder and elbow (4,539), foot and ankle (173,766), hand (366,300), and pediatric (489,683) fellowships reduce career NPV. In obstetrics and gynecology, reproductive endocrinology (352,854), and maternal and fetal medicine (322,511) fellowships improve career value, whereas gynecology oncology (28,101) and urogynecology (206,171) fellowships reduce career value. These data indicate that the financial return of fellowship is highly variable.

    Fernando Antonio Campelo Spencer Netto


    Full Text Available OBJECTIVE: To evaluate the acceptability of an educational project using A porcine model of airway for teaching surgical cricothyroidotomy to medical students and medical residents at a university hospital in southern Brazil.METHODS: we developed a teaching project using a porcine model for training in surgical cricothyroidotomy. Medical students and residents received lectures about this surgical technique and then held practical training with the model. After the procedure, all participants filled out a form about the importance of training in airway handling and the model used.RESULTS: There were 63 participants. The overall quality of the porcine model was estimated at 8.8, while the anatomical correlation between the model and the human anatomy received a mean score of 8.5. The model was unanimously approved and considered useful in teaching the procedure.CONCLUSION: the training of surgical cricothyroidotomy with a porcine model showed good acceptance among medical students and residents of this institution.

  2. The peritoneum as a natural scaffold for vascular regeneration.

    Directory of Open Access Journals (Sweden)

    Stefano Bonvini

    Full Text Available OBJECTIVE: The peritoneum has the same developmental origin as blood vessels, is highly reactive and poorly thrombogenic. We hypothesize that parietal peritoneum can sustain development and regeneration of new vessels. METHODS AND RESULTS: The study comprised two experimental approaches. First, to test surgical feasibility and efficacy of the peritoneal vascular autograft, we set up an autologous transplantation procedure in pigs, where a tubularized parietal peritoneal graft was covered with a metal mesh and anastomosed end-to-end in the infrarenal aorta. Second, to dissect the contribution of graft vs host cells to the newly developed vessel wall, we performed human-to-rat peritoneal patch grafting in the abdominal aorta and examined the origin of endothelial and smooth muscle cells. In pig experiments, the graft remodeled to an apparently normal blood vessel, without thrombosis. Histology confirmed arterialization of the graft with complete endothelial coverage and neointimal hyperplasia in the absence of erosion, inflammation or thrombosis. In rats, immunostaining for human mitochondri revealed that endothelial cells and smooth muscle cells rarely were of human origin. Remodeling of the graft was mainly attributable to local cells with no clear evidence of c-kit+ endothelial progenitor cells or c-kit+ resident perivascular progenitor cells. CONCLUSIONS: The parietal peritoneum can be feasibly used as a scaffold to sustain the regeneration of blood vessels, which appears to occur through the contribution of host-derived resident mature cells.

  4. Supplementary Educational Models in Canadian Neurosurgery Residency Programs. (United States)

    Ryu, Won Hyung A; Chan, Sonny; Sutherland, Garnette R


    The proposed implementation of work hour restrictions has presented a significant challenge of maintaining the quality of resident education and ensuring adequate hands-on experience that is essential for novice surgeons. To maintain the level of resident surgical competency, revision of the apprentice model of surgical education to include supplementary educational methods, such as laboratory and virtual reality (VR) simulations, have become frequent topics of discussion. We aimed to better understand the role of supplementary educational methods in Canadian neurosurgery residency training. An online survey was sent to program directors of all 14 Canadian neurosurgical residency programs and active resident members of the Canadian Neurosurgical Society (N=85). We asked 16 questions focusing on topics of surgeon perception, current implementation and barriers to supplementary educational models. Of the 99 surveys sent, 8 out of 14 (57%) program directors and 37 out of 85 (44%) residents completed the survey. Of the 14 neurosurgery residency programs across Canada, 7 reported utilizing laboratory-based teaching within their educational plan, while only 3 programs reported using VR simulation as a supplementary teaching method. The biggest barriers to implementing supplementary educational methods were resident availability, lack of resources, and cost. Work-hour restrictions threaten to compromise the traditional apprentice model of surgical training. The potential value of supplementary educational methods for surgical education is evident, as reported by both program directors and residents across Canada. However, availability and utilization of laboratory and VR simulations are limited by numerous factors such as time constrains and lack of resources.

    Full Text Available Introduction: Medical resident workload has been shown to be associated with learning efficiency and patient satisfaction. However, there is limited evidence about it in developing countries. This study aimed to evaluate the medical resident workload in a multidisciplinary teaching hospital in Tehran, Iran.Methods: All medical residents at Shariati Hospital, a teaching hospital affiliated with Tehran University of Medical Science, who were working between November and December 2011 were enrolled in this cross-sectional study. A self–reported questionnaire was used to gather information about their duty hours (including daily activities and shifts and financial issues.Results:135 (52.5% out of 257 residents responded to the questionnaire. 72 (53.3% residents were in surgical departments and 63 (46.7% were in non-surgical departments. Mean duty hours per month were significantly higher in surgical (350.8 ±76.7 than non-surgical (300.6±74.2 departments (p=0.001. Three cardiology (a non-surgical group residents (5.7% and 30 residents (41% in surgical groups (p<0.001 declared a number of “on-calls in the hospital” more than the approved number in the curriculum. The majority of residents (97.8% declared that their salary was not sufficient to manage their lives and they needed other financial resources. Conclusion: Medical residents at teaching hospitals in Iran suffer from high workloads and low income. There is a need to reduce medical resident workload and increase salary to improve worklife balance and finances.

    To present a model for integrated global health fellowships in plastic surgical residency training. National surveys have found that North American surgical residents have significant interest in international training. While global health training opportunities exist, less than a third of these are housed within surgical residency programs; even fewer are designed specifically for plastic surgery residents. The Tsao Fellowship was created through a partnership between Operation Smile, Children's Hospital Los Angeles, Shriners Hospital for Children, and the University of Southern California. Designed for Accreditation Council for Graduate Medical Education accredited plastic surgery residents between their third and fourth years of residency, the fellowship curriculum is completed over 24 months and divided into 3 areas: clinical research, international reconstructive surgery fieldwork, and the completion of a Master of Science in Clinical and Biomedical Investigations. The Tsao Fellowship has matriculated 4 fellows: 3 have graduated from the program and 1 is in the current cycle. Fellows completed 4 to 7 international missions each cycle and have performed an aggregate total of 684 surgical procedures. Each fellow also conducted 2 to 6 research projects and authored several publications. All fellows continue to assume leadership roles within the field of global reconstructive surgery. Comprehensive global health fellowships provide invaluable opportunities beyond surgical residency. The Tsao Fellowship is a model for integrating international surgical training with global health research in plastic surgical residency that can be applied to other residency programs and different surgical specialties.

  9. Four-year experience with a regional program providing simulation-based endovascular training for vascular surgery fellows. (United States)

    Dawson, David L; Lee, Eugene S; Hedayati, Nasim; Pevec, William C


    High-fidelity procedure simulation has been found useful for training vascular surgery residents in endovascular procedures, but the costs of acquiring, maintaining, and operating simulators represent a barrier to routine use of endovascular simulation in vascular surgery programs. Providing simulation training opportunities through regional centers may make simulation more cost effective, but the costs and benefits of this approach have not been reported previously. We reviewed participation costs in a regional simulation program to provide a benchmark for comparison with other training options. Simulation-based training was offered annually from 2004 to 2007 to the 11 vascular surgery fellowships in Washington, Oregon, California, Arizona, and Utah. Participation was at the discretion of the program directors and fellows. Sessions were designed to offer individualized, hands-on training with 2-4 participants per 2-day session. SimSuite (Medical Simulation Corporation, Denver, Colorado) simulators were used. During the 4-year period, participation by invited programs averaged 75%. Ten of 11 programs in the western United States region participated, with 34 fellows participating during the 4 years of the program. In addition, 2 program directors or faculty attended sessions to participate as learners, and 8 other individuals were allowed to participate (including 7 senior surgery residents and 1 vascular surgery fellow from out of the region). The average participant costs for travel, which include transportation, lodging, and meals, were $571. Simulation facility expenses, which included use of the simulator, computer-based training modules, and instructional support by an educational specialist, averaged $1055 per participant. Surgical faculty spent 12 hours per 2-day session instructing and in other direct educational activities. Costs for this time were not calculated separately.

  10. [Modern didactics in surgical education--between demand and reality]. (United States)

    Pape-Köhler, C; Chmelik, C; Rose, M; Heiss, M M


    Surgical residency contains an inadequate amount of hands-on training in the operating room and time constraints further make this type of education on the floor unlikely. Due to these deficits in residency training, private surgical courses outside of the established residency programmes are in high demand. Therefore, surgical residents must spend their own resources and time in addition to their residency training in order to receive adequate clinical exposure. Didactic approaches like problem-based learning have begun to influence our modern education. These novel education approaches along with visualisation training, video-based presentations, and multimedia-based training can be useful adjuncts to traditional surgical training. © Georg Thieme Verlag Stuttgart ˙ New York.

  11. Comparative vascular audit using the POSSUM scoring system.


    Copeland, G. P.; Jones, D.; Wilcox, A; Harris, P.L.


    Comparative audit using overall mortality and morbidity figures can be misleading as they do not take into account variations in surgical procedure and patient fitness. To examine these effects we have compared vascular surgery in two differing hospitals, during a similar 9-month period, using the POSSUM scoring system. In one unit, 255 patients underwent vascular surgery with an operative mortality of 9.4%, and morbidity of 37.3%. In the other unit, 89 patients underwent vascular procedures ...

  12. Surgical training in the Netherlands. (United States)

    Borel-Rinkes, Inne H M; Gouma, Dirk J; Hamming, Jaap F


    Surgical training in the Netherlands has traditionally been characterized by learning on the job under the classic master-trainee doctrine. Over the past decades, it has become regionally organized with intensive structural training courses, and a peer-based quality control system. Recently, the nationwide programme has been modernized further and now involves a systematic, competency-based education with structural training courses, formalized assessment and room for reflection by residents under the supervision of surgical teaching groups. To this end, a uniform web-based digital portfolio is being introduced to facilitate monitoring of the individual resident's progress. Though requiring inspirational leadership, commitment, and determination, this modernization has sparked enthusiasm among trainees and teachers.

  13. Vascular Injury in Orthopedic Trauma. (United States)

    Mavrogenis, Andreas F; Panagopoulos, George N; Kokkalis, Zinon T; Koulouvaris, Panayiotis; Megaloikonomos, Panayiotis D; Igoumenou, Vasilios; Mantas, George; Moulakakis, Konstantinos G; Sfyroeras, George S; Lazaris, Andreas; Soucacos, Panayotis N


    Vascular injury in orthopedic trauma is challenging. The risk to life and limb can be high, and clinical signs initially can be subtle. Recognition and management should be a critical skill for every orthopedic surgeon. There are 5 types of vascular injury: intimal injury (flaps, disruptions, or subintimal/intramural hematomas), complete wall defects with pseudoaneurysms or hemorrhage, complete transections with hemorrhage or occlusion, arteriovenous fistulas, and spasm. Intimal defects and subintimal hematomas with possible secondary occlusion are most commonly associated with blunt trauma, whereas wall defects, complete transections, and arteriovenous fistulas usually occur with penetrating trauma. Spasm can occur after either blunt or penetrating trauma to an extremity and is more common in young patients. Clinical presentation of vascular injury may not be straightforward. Physical examination can be misleading or initially unimpressive; a normal pulse examination may be present in 5% to 15% of patients with vascular injury. Detection and treatment of vascular injuries should take place within the context of the overall resuscitation of the patient according to the established principles of the Advanced Trauma Life Support (ATLS) protocols. Advances in the field, made mostly during times of war, have made limb salvage the rule rather than the exception. Teamwork, familiarity with the often subtle signs of vascular injuries, a high index of suspicion, effective communication, appropriate use of imaging modalities, sound knowledge of relevant technique, and sequence of surgical repairs are among the essential factors that will lead to a successful outcome. This article provides a comprehensive literature review on a subject that generates significant controversy and confusion among clinicians involved in the care of trauma patients.

  14. Accreditation Council for Graduate Medical Education (ACGME) Surgery Resident Operative Logs: The Last Quarter Century. (United States)

    Drake, Frederick Thurston; Aarabi, Shahram; Garland, Brandon T; Huntington, Ciara R; McAteer, Jarod P; Richards, Morgan K; Zern, Nicole Kansier; Gow, Kenneth W


    To describe secular trends in operative experience for surgical trainees across an extended period using the most comprehensive data available, the Accreditation Council for Graduate Medical Education (ACGME) case logs. Some experts have expressed concern that current trainees are inadequately prepared for independent practice. One frequently mentioned factor is whether duty hours' restrictions (DHR) implemented in 2003 and 2004 contributed by reducing time spent in the operating room. A dataset was generated from annual ACGME reports. Operative volume for total major cases (TMC), defined categories, and four index laparoscopic procedures was evaluated. TMC dropped after implementation of DHR but rebounded after a transition period (949 vs 946 cases, P = nonsignificance). Abdominal cases increased from 22% of overall cases to 31%. Alimentary cases increased from 21% to 26%. Trauma and vascular surgery substantially decreased. For trauma, this drop took place well before DHR. The decrease in vascular surgery also began before DHR but continued afterward as well: 148 cases/resident in the late 1990s to 107 currently. Although total operative volume rebounded after implementation of DHR, diversity of operative experienced narrowed. The combined increase in alimentary and abdominal cases is nearly 13%, over a half-year's worth of operating in 5-year training programs. Bedrock general surgery cases-trauma, vascular, pediatrics, and breast-decreased. Laparoscopic operations have steadily increased. If the competence of current graduates has, in fact, diminished. Our analysis suggests that operative volume is not the problem. Rather, changing disease processes, subspecialization, reductions in resident autonomy, and technical innovation challenge how today's general surgeons are trained.

  15. Smart(phone) Learning Experience Among Vascular Trainees Using a Response System Application. (United States)

    Al-Jundi, Wissam; Kayssi, Ahmed; Papia, Giuseppe; Dueck, Andrew

    Smartphones have become the most important personal technological device. M-learning is learning through mobile device educational technology. We aim to assess the acceptability of a smartphone learning experience among the vascular trainees and determine if results could inform formal teaching efforts. A survey of the vascular trainees at a single center was conducted following a trial of smartphone learning experience. A vascular fellow used a smartphone response system application (Polltogo, Inspirapps Inc.) to send a daily multiple-choice question to the vascular residents for 20 consecutive working days. The application allows for only one attempt from each user, and the answers are registered anonymously. However, each participant receives instant feedback on his/her response by viewing the correct answer after answering each question along with a distribution of answers among other users. A total of 9 trainees participated in the trial, and all of them filled a posttrial survey. All the trainees possessed smartphones. The majority (78%) were not aware of the concept of m-learning. The mobile engagement score (number of answers received divided by total possible answers) was 145/180 (81%). All the trainees were "satisfied" or "very satisfied" with the experience, and the same number stated that they were "likely" or "very likely" to use this technology in the future. The majority (89%) agreed that such an application could assist them in preparing for their board examination. On 3 occasions, 75% or more of the participating trainees answered the multiple-choice question incorrectly, which resulted in addressing the relevant topics in the unit's weekly teaching conference. Using smartphones for education is acceptable among the vascular trainees, and the trial of a response system application with instant written feedback represents a novel method for using smartphones for collaborative learning. Such an application can also inform program directors and

    Vascular trauma is a common life threatening injury leading to serious consequences if not timely and efficiently managed. We evaluated early surgical interventions aimed at revascularization and thus salvaging limb/organ in life threatening vascular injuries. Aims of our study were to evaluate the outcome of available diagnostic modalities, earliest possible surgical intervention and rate of related complications with particular reference to our existing situation. Emergency diagnostic workup based mainly on clinical evaluations and required laboratory and imaging parameters leading to revascularisation was performed in 48 patients in Combined Military Hospital (CMH) Muzaffarabad and Islamic Medical College Hospitals between June 1997 and December 2001. Data was collected on pre-designed computerized proforma's which were completed by the treating surgeon and data was entered and analyzed accordingly. Out of the total 48 patients who sustained major vascular injuries during this period, 14 (29.2%) were having injury to upper limb vessels, 26 (54.2%) patients had injury to the lower limb vessels, 6 (12.5%) patients reported with injury to abdominal vessels. One (2%) patient had injury to common carotid artery, while an other patient to thoracic aorta respectively (2%). Penetrating trauma caused 38 (79%) and blunt trauma caused 10 (21%) major vascular injuries. Out of 48 patients, 41 (85.4%) patients were successful managed by vascular reconstruction without any residual disability. Speedy diagnostic work up and early revascularization yields favourable outcome in vast majority of patients requiring vascular repair. Selections of surgical technique including use of autologous vein graft or artificial vascular graft can save many limbs. In order to achieve good results the time lapse between injury and revascularisation should be less than 6 hours.

  18. Evolution of surgical skills training

    Surgical training is changing: one hundred years of tradition is being challenged by legal and ethical concerns for patient safety, work hours restrictions, the cost of operating room time, and complications. Surgical simulation and skills training offers an opportunity to teach and practice advanced skills outside of the operating room environment before attempting them on living patients.Simulation training can be as straight forward as using real instruments and video equipment to manipulate simulated "tissue" in a box trainer. More advanced,virtual reality simulators are now available and ready for widespread use. Early systems have demonstrated their effectiveness and discriminative ability. Newer systems enable the development of comprehensive curricula and full procedural simulations.The Accreditation Council of Graduate Medical Education's (ACGME) has mandated the development of novel methods of training and evaluation. Surgical organizations are calling for methods to ensure the maintenance of skills, advance surgical training, and to credential surgeons as technically competent.Simulators in their current form have been demonstrated to improve the operating room performance of surgical residents. Development of standardized training curricula remains an urgent and important agenda, particularly for minimal invasive surgery.An innovative and progressive approach, borrowing experiences from the field of aviation, can provide the foundation for the next century of surgical training,ensuring the quality of the product. As the technology develops, the way we practice will continue to evolve, to the benefit of physicians and patients.

  19. [Surgical education has its price]. (United States)

    Schröder, W; Krones, C J


    The radical economisation of the German health-care system has caused an increasing cost awareness. Following this trend, medical education has been identified as a possible expense factor. The theoretical and practical training of young doctors needs time and costs money. However, a detailed cost analysis is still not available, since the complex daily work schedule of young professionals only allows the calculation of single cost factors. Investigations in the USA estimate the costs of surgical training at US$ 80 000 per year and per resident. At present in Germany, surgical training is indirectly financed by the DRG flat rates of the health insurance companies. Possible alternatives include the implementation of a "training fond" which is financed by a percentage fee of the DRG's as well as an on-top funding by the federal government. This "training fond" would support only those surgical units that offer a structured and certified training to surgical residents. However, a systematic cost analysis of such a structured curriculum is necessary for any further discussion.

  1. Vascular development in Arabidopsis. (United States)

    Ye, Zheng-Hua; Freshour, Glenn; Hahn, Michael G; Burk, David H; Zhong, Ruiqin


    Vascular tissues, xylem and phloem, form a continuous network throughout the plant body for transport of water, minerals, and food. Characterization of Arabidopsis mutants defective in various aspects of vascular formation has demonstrated that Arabidopsis is an ideal system for investigating the molecular mechanisms controlling vascular development. The processes affected in these mutants include initiation or division of procambium or vascular cambium, formation of continuous vascular cell files, differentiation of procambium or vascular cambium into vascular tissues, cell elongation, patterned secondary wall thickening, and biosynthesis of secondary walls. Identification of the genes affected by some of these mutations has revealed essential roles in vascular development for a cytokinin receptor and several factors mediating auxin transport or signaling. Mutational studies have also identified a number of Arabidopsis mutants defective in leaf venation pattern or vascular tissue organization in stems. Genetic evidence suggests that the vascular tissue organization is regulated by the same positional information that determines organ polarity.

  2. Arthroscopic Posterior Subtalar Arthrodesis: Surgical Technique (United States)

    Vilá y Rico, Jesús; Ojeda Thies, Cristina; Parra Sanchez, Guillermo


    Surgical fusion of the subtalar joint is a procedure indicated to alleviate pain of subtalar origin, such as in post-traumatic osteoarthritis, adult-acquired flatfoot deformity, and other disorders. Open subtalar arthrodesis has been performed with predictable results, but concerns exist regarding injury to proprioception and local vascularity due to wide surgical dissection. Minimally invasive techniques try to improve results by avoiding these issues but have a reputation for being technically demanding. We describe the surgical technique for arthroscopic subtalar arthrodesis, which has proved to be a safe and reliable technique in our experience, with consistent improvements in American Orthopaedic Foot & Ankle Society scores.

  4. Are neurology residents interested in headache? (United States)

    Gago-Veiga, A B; Santos-Lasaosa, S; Viguera Romero, J; Pozo-Rosich, P


    The years of residency are the pillars of the subsequent practice in every medical specialty. The aim of our study is to evaluate the current situation, degree of involvement, main interests, and perceived quality of the training received by Spanish residents of neurology, specifically in the area of headache. A self-administered survey was designed by the Headache Study Group of the Spanish Society of Neurology (GECSEN) and was sent via e-mail to all residents who were members of the Society as of May 2015. Fifty-three residents completed the survey (N = 426, 12.4%): 6% were first year residents, 25.5% second year, 23.5% third year, and 45% fourth year residents, all from 13 different Spanish autonomous communities. The areas of greatest interest are, in this order: Vascular neurology, headache, and epilepsy. Of them, 85% believe that the area of headache is undervalued. More than half of residents (52.8%) do not rotate in specific Headache Units and only 35.8% complete their training dominating anaesthetic block and toxin infiltration techniques. Of them, 81.1% believe that research is scarce or absent; 69.8% have never made a poster/presentation, 79.3% have not published and only 15% collaborate on research projects in this area. Lastly, 40% believe that they have not received adequate training. Headache is among the areas that interest our residents the most; however, we believe that we must improve their training both at a patient healthcare level and as researchers. Thus, increasing the number of available courses, creating educational web pages, involving residents in research, and making a rotation in a specialised unit mandatory are among the fundamental objectives of the GECSEN.

Elements of blood auto transfused are a little or not at all altered. Autotransfusion reduces requiremnts of bank blood, rare and containing risks.

  6. Advanced airway management teaching in otolaryngology residency programs in Canada: A survey of residents. (United States)

    Côté, Valérie; Kus, Lukas H; Zhang, Xun; Richardson, Keith; Nguyen, Lily H


    We conducted a study to assess residents' levels of comfort with advanced airway management in Canadian otolaryngology residency programs. In October 2008, an electronic questionnaire was sent to all otolaryngology residents in Canada. Responses were voluntary and anonymous. The response rate was 64.8% (94 of 145 residents). Residents were asked about the amount of teaching they received and the amount they would like to receive each year in four areas: emergency surgical airway, pediatric airway, airway trauma, and management of complications during laryngoscopy/bronchoscopy. They were also asked how comfortable they were with their current level of knowledge in these areas. Overall, residents were not comfortable with difficult airway situations, scoring a mean of 3.08 on a 5-point Likert scale. Residents were most comfortable with the emergency airway and least comfortable with the pediatric airway. Overall, residents indicated that they had not received adequate teaching on advanced airway management, and they consistently desired more. With respect to the type of instruction, most residents requested more teaching via simulations, mannequins, and cadaver or animal models. Linear regression models revealed a positive relationship between their overall comfort with airway management and the number of airway teaching hours they received. Their consensus was that formal airway training should occur during postgraduate year (PGY) 2, with refresher courses offered every 2 years. This is the first wide-scale assessment of the status of airway teaching in otolaryngology residency programs in Canada. Overall, our findings suggest that otolaryngology residents in these programs are not comfortable with advanced airway management early in their training and feel they would benefit from a significant increase in airway teaching time. Comfort levels improved with increasing levels of training such that PGY5 residents indicated they were indeed comfortable with advanced

    Rathat, G; Hoa, D; Gagnayre, R; Hoffet, M; Mares, P


    Describe the surgical training of gynecologic residents in the operating room, by collecting the opinion of French gynecologists. A questionnaire investigating this subject was put on a web site. Every French gynecologist could answer the questionnaire from a duration of six months. The data of the inquiry were studied by comparing five groups: residents (group 1), fellows (group 2), seniors of public hospital (group 3), and seniors of private hospitals (group 4), or, groups 2, 3 and 4 together, as Group A. Six hundred and fifty-seven gynecologists answered the inquiry. For the residents, lack of time and senior's weak educational motivation are the explanations most frequently retained in order to explain that residents do not operate. For group A, it is rather the residents' skills which is the most important fact to have residents operate. Residents more often practice surgery in general public hospital that in faculty hospital. For 31% of all the referees, heads of departments do not incite their teams to have residents operate. Nearly 25% of all the investigated believe that a man operates more than a woman in resident curriculum. Besides, by analyzing the answers of groups 1 and 2, we were able to correlate resident seniority at their first practice of 13 surgical operations. For 26% of the group A, residents operate less than they do during their own studies. Finally, all the investigated confirm the lack of surgical assessment in the resident curriculum. Decision to let the resident operate remains too dependent on senior personal appreciation and does not seem to join a strategy of training. Opinions of surgical training in the operating room is different between residents and seniors. Operating time increases when residents operate but there is no effect on quality of care. These results show again the necessity of a formal teaching and assessment, in a resident program with objectives, collecting every resident's surgery volume. These educational

    Objective To document the effectiveness and patient experience of surgical treatment for diabetic lower limb arterial occlusion. Methods Out of 290 diabetic patients with lower limb arterial occlusion, 69 received by-pass operation because of severe stenosis below the abdominal aorta and severe ulcers in feet from April 2004 to April 2011. We reviewed the experience and outcome of the 69 diabetic patients who underwent surgical operations on lower limb arterial occlusion. Results 100% initial surgical success was achieved. The morbidity (excluding death) was 12. 3% + 4. 1% and 15. 7% ±5. 1% at 1 year and 3 years after operations, respectively. Five (7. 2%) death cases were recorded, which resulted in a survival rate of 94. 2%±2. 8% and 92. 0%±3. 5% at 1 year and 3 years after operations, respectively. About 90. 6%+ 3. 6% and 87. 2%±4. 9% of patients had graft patency 1 year and 3 years after operations, respectively; and 6. 5% + 3. 1% had amputations. Four (5. 8%) patients developed graft thrombosis, in which 2 (2. 9%) had amputations because of recurrence of thrombosis after thrombectomy. Two (2. 9%) patients had amputations because of graft infection accompanied with graft resection operations. One (1.4%) patient received repeated arterialized operation on great saphenous vein because of popliteal artery occlusion, and obtained a good outcome within two years. One (1. 4%) patient developed stomas false aneurysm, but the excision of the false aneurysm resulted in a good outcome in four years. Conclusion Detailed pre-operation assessment, optimal selection of surgical procedure and perioperative management can help improve the outcome of diabetes and decrease amputation rate in patients with diabetic lower limb arterial occlusion.%目的 总结糖尿病足下肢动脉闭塞病变的外科血管搭桥(BPG)治疗经验及体会.方法 回顾性分析2004年4月至2011年4月收治糖尿病足临界性肢体缺血(CLI)的290例患者中69例选择外科BPG方式

  12. The vascular hybrid room--operating room of the future. (United States)

    Hudorović, Narcis; Rogan, Suncica Andreja; Lovricević, Ivo; Zovak, Mario; Schmidt, Sasa


    The last two decades have seen a paradigm shift in the treatment of vascular related diseases from once traditional open surgical repairs to the entire vascular tree being amenable to percutaneous interventions. Neither the classic operating room nor the conventional angiography suite is optimal for both open surgery and endovascular procedures. Important issues for the vascular hybrid operating room include quality of the imaging equipment, radiation burden, ease of use of the equipment, need for specially trained personnel, ergonomics, ability to perform both open and percutaneous procedures, sterile environments, as well as quality and efficiency of patient care. The most important feature of working in a dedicated hybrid vascular suite should be the ability to attain best treatment of vascular patients. Whether the interventional radiologist or the vascular surgeon uses the facilities is of less importance. Establishment of an endovascular operating room suite has the benefit of a sterile environment, and the possibility of performing hybrid procedures and conversions when necessary. Moreover, angiography immediately before treatment gives contemporary anatomical information, and after treatment provides quality control. Consequently, better quality and service can be provided to the individual patient. These changes in the treatment of vascular disease require that a new type of vascular specialist, named 'vascular hybrid surgeon', trained to perform both endovascular and open surgical procedures in this highly complex patient group.

  13. Assessment of risk of peripheral vascular disease and vascular care capacity in Ghana (United States)

    Introduction This study aimed to describe national peripheral vascular disease (PVD) risk and health burden and vascular care capacity in Ghana. The gap between PVD burden and vascular care capacity in a low- and middle-income country (LMIC) is defined and capacity improvement priorities identified. Methods Data to estimate PVD risk factor burden were obtained from: i) World Health Organization’s Study on Global Ageing and Health (SAGE), Ghana; and ii) Institute of Health Metrics and Evaluation Global Burden of Disease database (IHME GBD). In addition, a novel nationwide assessment of vascular care capacity was performed, with 20 vascular care items assessed at 40 hospitals in Ghana. Factors contributing to specific item deficiency were also described. Results From the SAGE database, there were 4,305 respondents aged at least 50 years with data to estimate PVD risk. Out of these 57% were at moderate to high PVD risk with ≥3 risk factors, thus giving 1,654,557 persons when extrapolated nationally. Using IHME GBD data, the estimated disability-adjusted life years incurred from PVD increased 5-fold from 1990 to 2010 (1.3 to 3.2 per 100,000 persons, respectively). Vascular care capacity assessment demonstrated marked deficiencies in items for diagnosis, perioperative and vascular surgical care. Deficiencies were most often due to absence of equipment, lack of training and technology breakage. Conclusion Risk factor reduction and management as well as optimization of current resources are paramount to avoid the large burden of peripheral vascular disease falling on healthcare systems in low- and middle-income countries that are not well equipped to handle vascular surgical care, and for which rapid development of such capacity would be difficult and expensive.

  14. Emotional Intelligence as a Predictor of Resident Well-Being. (United States)

    Lin, Dana T; Liebert, Cara A; Tran, Jennifer; Lau, James N; Salles, Arghavan


    There is increasing recognition that physician wellness is critical; it not only benefits the provider, but also influences quality and patient care outcomes. Despite this, resident physicians suffer from a high rate of burnout and personal distress. Individuals with higher emotional intelligence (EI) are thought to perceive, process, and regulate emotions more effectively, which can lead to enhanced well-being and less emotional disturbance. This study sought to understand the relationship between EI and wellness among surgical residents. Residents in a single general surgery residency program were surveyed on a voluntary basis. Emotional intelligence was measured using the Trait Emotional Intelligence Questionnaire-Short Form. Resident wellness was assessed with the Dupuy Psychological General Well-Being Index, Maslach Burnout Inventory, and Beck Depression Inventory-Short Form. Emotional intelligence and wellness parameters were correlated using Pearson coefficients. Multivariate analysis was performed to identify factors predictive of well-being. Seventy-three residents participated in the survey (response rate 63%). Emotional intelligence scores correlated positively with psychological well-being (r = 0.74; p emotional exhaustion (r = -0.69; p emotional exhaustion (β = -0.63; p Emotional intelligence is a strong predictor of resident well-being. Prospectively measuring EI can identify those who are most likely to thrive in surgical residency. Interventions to increase EI can be effective at optimizing the wellness of residents.

  15. Missed vascular injuries: presentation and outcome. (United States)

    Siddique, Muhammad Khalid; Majeed, Shahid; Irfan, Muhammad; Ahmad, Nisar


    To describe the different presentation, diagnostic evaluation, management and outcome of complications of missed vascular injuries. A case series. Combined Military Hospital, Rawalpindi and Combined Military Hospital, Kharian Cantt, from June 2009 to June 2012. All the patients with vascular injuries missed at the time of causative trauma who reported during this study period were included. Patients presented with acute vascular injuries and iatrogenic aneurysm at the vascular anastomosis site were excluded. All cases were evaluated with either CT or conventional angiography and managed with various open vascular surgical techniques and their results were assessed. Twenty eight patients with missed vascular injury underwent various vascular repairs. Age of patients ranged from 16 to 78 years (mean = 33.7 ± 15.4 years). Male to female ratio was 6:1. Twelve (42.8%) patients presented with pseudoaneurysm alone, 10 (35.7%) with traumatic arteriovenous fistulae, 4 (14.3%) with post-traumatic thrombosis and occlusion and 2 (7.1%) with pseudoaneurysm and hemorrhage. Penetrating injuries were the commonest cause in 19 (67.8%). The time interval between injury and presentation in hospital ranged from 2 to 1300 weeks (mean 228 weeks). Lower limb vessels were affected in 20 (71.4%), the upper limb in 5 (17.8%) and neck vessels in 3 (10.7%). Superficial femoral artery was the most frequently involved artery in 9 (32.1%) cases. Interposition reverse autogenous saphenous vein graft was most common type of repair in all types of missed vascular injuries. One (3.5%) patient had amputation after secondary hemorrhage. Low velocity penetrating trauma was the common cause of missed vascular injury. Pseudoaneurysm was the most common presentation.

We review our experience with consult services dedicated to the needs of these frail patients.Study design: Patients were prospectively followed after being evaluated by three different geriatric surgical consult services: Group 1 was based at a geriatric center associated with a tertiary medical center, Group 2 was based at a community geriatric center, and Group 3 was based with an hospital-based service for ambulatory patients with end stage congestive heart failure.Results: A total of 256 frail elderly patients underwent of 311 general surgical procedures ranging from major abdominal and vascular procedures to minor procedures such as debridement of decubitus ulcers, long-term intravenous access, enterostomy and enteral tube placement. Almost half of the surgical volume in Group 1 and 3 were ‘maintenance’ (decubitus debridement, long term intravenous or stomal or tube care; all of Group 2 were for treatment of decubiti. There was minimal morbidity and mortality from surgery itself, and overall one year survival for Groups 1, 2, and 3 was 46%, 60%, and 79%, respectively. Multivariate analysis showed that each group had its own unique indicators of decreased survival: Group 1 dementia and coronary artery disease, in Group 2 gender and coronary artery disease, and Group 3, gender alone. Age, number of comorbid illnesses, and type of surgery (major vs minor were not significant indicators.Conclusions: This is the first review of the role of dedicated surgical consult services which focused on residents of geriatric centers and frail elderly.

    Franco, Gianfábio Pimentel; de Barros, Alba Lúcia Bottura Leite; Nogueira-Martins, Luiz Antônio; Zeitoun, Sandra Salloum


    Nursing residents may experience physical and emotional exhaustion from the daily life of attending the Program. The aim of this study was to determine the Burnout incidence among Nursing Residents. An investigative, descriptive, analytical, longitudinal-prospective study was conducted with 16 Residents over two years. The Maslach Burnout Inventory was used, translated and validated for Brazil, as well as a sociodemographic/occupational data tool. Of all residents, 17.2% showed high rates in Emotional Exhaustion and Depersonalization; 18.8% showed impaired commitment in Personal Accomplishment, 75% of which belonged to specialty areas, such as Emergency Nursing, Adult and Pediatric Intensive Care. Age and specialty area were positively correlated with Personal Accomplishment. One of the Residents was identified with changes in three subscales of the Maslach Burnout Inventory, thus characterized as a Burnout Syndrome patient. Nursing Residents have profiles of disease. Knowing these factors can minimize health risks of these workers.

  2. Supply versus demand: a review of application trends to Canadian surgical training programs. (United States)

    Austin, Ryan E; Wanzel, Kyle R


    Despite increases in medical school enrolment, applications to surgical residency programs in Canada have been in decline over the past decade, with an increasing number of unmatched surgical residency positions. We examined the current status of surgical residency in Canada and analyzed application trends (2002–2013) for surgical training programs across Canada. Our findings suggest that most undergraduate medical schools across Canada are having difficulty fostering interest in surgical careers. We propose that a lack of adequate early exposure to the surgical specialties during undergraduate training is a critical factor. Moving forward, we must examine how the best-performing institutions and surgical programs have maintained interest in pursuing surgical careers and adapt our recruitment methods to both maintain and grow future interest. As Mary Engelbreit said, "If you don't like something, change it; if you can't change it, change the way you think about it."

  3. Accidental blood exposures among medical residents in Paris, France. (United States)

    Mir, O; Adam, J; Veyrie, N; Chousterman, B; Gaillard, R; Gregory, T; Yordanov, Y; Berveiller, P; Loulergue, P


    Accidental blood exposure (ABE) exposes healthcare workers, including medical residents, to the risk of occupational infection. We aimed to determine the characteristics of ABEs in residents with an anonymous self-reporting electronic questionnaire. A total of 350 residents (33% from surgical disciplines) entered this survey. One hundred and eighty-five residents (52%) reported at least one ABE during their residency (median, 2; range, 1-25), 53% of which occurred in operating theatres. Sixty-nine per cent of residents followed the current procedures for local disinfection. ABEs were notified to the hospital administration by 62% of residents, but only 51% of residents were referred to the occupational medicine department. The most frequently reported concerns following ABEs were human immunodeficiency virus (52%) and hepatitis C virus infection (39%). In 74% of cases, the serological status of the index patient was investigated. Only 54% of residents were aware of their hepatitis B surface antibody titres. Medical residents behaved inappropriately in 33% of cases in this survey. Further educational programmes should include residents, and not only senior healthcare workers, in order to improve individual behaviours.

  5. Colorectal surgeons teaching general surgery residents: current challenges and opportunities. (United States)

    Schmitz, Connie C; Chow, Christopher J; Rothenberger, David A


    Effective teaching for general surgery residents requires that faculty members with colorectal expertise actively engage in the education process and fully understand the current context for residency training. In this article, we review important national developments with respect to graduate medical education that impact resident supervision, curriculum implementation, resident assessment, and program evaluation. We argue that establishing a culture of respect and professionalism in today's teaching environment is one of the most important legacies that surgical educators can leave for the coming generation. Faculty role modeling and the process of socializing residents is highlighted. We review the American College of Surgeons' Code of Professional Conduct, summarize some of the current strategies for teaching and assessing professionalism, and reflect on principles of motivation that apply to resident training both for the trainee and the trainer.

  6. Risk-adjusted morbidity in teaching hospitals correlates with reported levels of communication and collaboration on surgical teams but not with scale measures of teamwork climate, safety climate, or working conditions. (United States)

    Davenport, Daniel L; Henderson, William G; Mosca, Cecilia L; Khuri, Shukri F; Mentzer, Robert M


    Since the Institute of Medicine patient safety reports, a number of survey-based measures of organizational climate safety factors (OCSFs) have been developed. The goal of this study was to measure the impact of OCSFs on risk-adjusted surgical morbidity and mortality. Surveys were administered to staff on general/vascular surgery services during a year. Surveys included multiitem scales measuring OCSFs. Additionally, perceived levels of communication and collaboration with coworkers were assessed. The National Surgical Quality Improvement Program was used to assess risk-adjusted morbidity and mortality. Correlations between outcomes and OCSFs were calculated and between outcomes and communication/collaboration with attending and resident doctors, nurses, and other providers. Fifty-two sites participated in the survey: 44 Veterans Affairs and 8 academic medical centers. A total of 6,083 surveys were returned, for a response rate of 52%. The OCSF measures of teamwork climate, safety climate, working conditions, recognition of stress effects, job satisfaction, and burnout demonstrated internal validity but did not correlate with risk-adjusted outcomes. Reported levels of communication/collaboration with attending and resident doctors correlated with risk-adjusted morbidity. Survey-based teamwork, safety climate, and working conditions scales are not confirmed to measure organizational factors that influence risk-adjusted surgical outcomes. Reported communication/collaboration with attending and resident doctors on surgical services influenced patient morbidity. This suggests the importance of doctors' coordination and decision-making roles on surgical teams in providing high-quality and safe care. We propose risk-adjusted morbidity as an effective measure of surgical patient safety.

  7. [Proposal of residency integrated with medical masters degree at the UFMG Medical School: an evaluation among residents]. (United States)

    Lamounier, J A; Pereira, A A; de Oliveira, H N


    A project which integrates medical RESIDENCY with medical masters degree has been discussed and is expected to be set up at UFMG Medical School in the near future. Such project is optional for the entering residents and aims those who are interested in becoming researchers. This paper's objective is to raise the residents' opinion on the project as well as their interests in post graduation level. A 240 university hospital residents (HC-UFMG) and a 114 non-university hospital (IPSEMG) were studied through questionnaire application. From the total population of 354 residents we had a 50% questionnaire devolution, 120 (68%) from HC-UFMG and 57 (32%) from IPSEMG. Residents of different clinical and surgical areas were included, 55% male and 45% female. Most of them work exclusively in residency activities, 69% have interest in specialize after residency, 55% in taking medical masters degree, 52% in taking up academic life and 67% in applying for the integrated residency-master degree program. Twelve (7%) are not particularly interested in join the program because they are not sure whether they are able to carry on adequately both residency and research activities at the same time. This study shows that residents are highly receptive to the UFMG's program and that more detailed information concerning its contents should be handed out in order to generate further discussion.

  8. Vascular malformations of the mandible (intraosseous haemangiomas)

    Energy Technology Data Exchange (ETDEWEB)

    Guibert-Tranier, F.; Piton, J.; Caille, J.M.; Riche, M.C.; Merland, J.J.


    Haemangiomas of the mandible are relatively rare arteriovenous malformations: 85 cases have been described since 1849. The severe risk of bleeding during tooth extraction or biopsy led us to describe the radiological and angiographic features of this condition. The afferent vessles are the inferior dental, the lingual and the facial arteries. Preoperative embolization reduces the risk of bleeding at operation. Surgical treatment must assure the complete removal of the lesion. Radiotherapy and vascular ligatures are useless and dangerous.

  9. Isolated plexiform neurofibroma mimicking a vascular lesion* (United States)

    Stefano, Paola Cecilia; Apa, Sebastian Nicolas; Lanoël, Agustina Maria; María, Josefina Sala; Sierre, Sergio; Pierini, Adrián Martin


    Plexiform neurofibromas are benign tumors originating from peripheral nerve sheaths, generally associated with Neurofibromatosis Type 1 (NF1). They are diffuse, painful and sometimes locally invasive, generating cosmetic problems. This report discusses an adolescent patient who presented with an isolated, giant plexiform neurofibroma on her leg that was confused with a vascular lesion due to its clinical aspects. Once the diagnosis was confirmed by surgical biopsy, excision of the lesion was performed with improvement of the symptoms. PMID:27192529

  10. [What do general, abdominal and vascular surgeons need to know on plastic surgery - aspects of plastic surgery in the field of general, abdominal and vascular surgery]. (United States)

    Damert, H G; Altmann, S; Stübs, P; Infanger, M; Meyer, F


    There is overlap between general, abdominal and vascular surgery on one hand and plastic surgery on the other hand, e.g., in hernia surgery, in particular, recurrent hernia, reconstruction of the abdominal wall or defect closure after abdominal or vascular surgery. Bariatric operations involve both special fields too. Plastic surgeons sometimes use skin and muscle compartments of the abdominal wall for reconstruction at other regions of the body. This article aims to i) give an overview about functional, anatomic and clinical aspects as well as the potential of surgical interventions in plastic surgery. General/abdominal/vascular surgeons can benefit from this in their surgical planning and competent execution of their own surgical interventions with limited morbidity/lethality and an optimal, in particular, functional as well as aesthetic outcome, ii) support the interdisciplinary work of general/abdominal/vascular and plastic surgery, and iii) provide a better understanding of plastic surgery and its profile of surgical interventions and options.

  11. Pediatric peripheral vascular injuries: a review of our experience. (United States)

    Shah, Sohail R; Wearden, Peter D; Gaines, Barbara A


    This study evaluated peripheral vascular injuries in a pediatric trauma population to identify injury patterns, to identify diagnostic and therapeutic modalities used, and to understand the role of pediatric surgical subspecialists. A retrospective review of children treated for trauma between 2000 and 2006 at a Level I Pediatric Trauma Center was performed. Patients with vascular injury were identified through an institutional trauma registry. There were 42 vascular injuries identified during the study period. The average age was 9.8 years, with 64% occurring in males. The mechanism of injury was almost equally distributed between penetrating (55%) and blunt (45%) trauma. Forty-eight percent of patients had an associated fracture. Seventeen diagnostic angiograms were performed. Ninety-eight percent of patients were taken to the operating room for definitive management of one or more of their trauma injuries. Sixty-seven percent underwent operative management specifically for their vascular injury. Twenty-six percent of patients were diagnosed with vasospasm, and all were conservatively managed. Of the 42 patients, 23% were managed by pediatric surgeons, 43% by extremity specialists (orthopedic or plastic surgeons), and 29% by adult vascular surgeons. Pediatric traumatic vascular injuries are associated with a higher rate of penetrating trauma than other pediatric trauma and have a relatively high rate of operative intervention. Diagnosis and treatment of pediatric vascular injuries can be made difficult by a high rate of vasospasm. Additionally, traumatic vascular injuries in the pediatric population present a unique challenge in the overlap of their management by many different surgical subspecialists.

  12. Evaluation and management of acute vascular trauma. (United States)

    Salazar, Gloria M M; Walker, T Gregory


    With the technical advances and the increasing availability of sophisticated imaging equipment, techniques, and protocols, and with continually evolving transcatheter endovascular therapies, minimally invasive imaging and treatment options are being routinely used for the clinical management of trauma patients. Thus, the primary treatment algorithm for managing acute vascular trauma now increasingly involves the interventional radiologist or other endovascular specialist. Endovascular techniques represent an attractive option for both stabilizing and definitively treating patients who have sustained significant trauma, with resultant vascular injury. Endovascular treatment frequently offers the benefit of a focused definitive therapy, even in the presence of massive hemorrhage that allows for preservation of major vessels or injured solid organs and serves as an alternative to an open surgical intervention. This article presents an overview of various endovascular techniques that can be used for trauma patients presenting with vascular injuries.

  13. Vascular access for hemodialysis: arteriovenous fistula. (United States)

    Malovrh, Marko


    The long-term survival and quality of life of patients on hemodialysis (HD) is dependant on the adequacy of dialysis via an appropriately placed vascular access. The optimal vascular access is unquestionably the autologous arteriovenous fistula (AVF), with the most common method being the conventional radio-cephalic fistula at the wrist. Recent clinical practice guidelines recommend the creation of native fistula or synthetic graft before the start of chronic HD therapy to prevent the need for complication-prone dialysis catheters. This could also have a beneficial effect on the rapidity of worsening kidney failure. A multidisciplinary approach (nephrologists, surgeons, radiologists and nurses) should improve the HD outcome by promoting the use of AVF. An important additional component of this program is the Doppler ultrasound for preoperative vascular mapping. Such an approach may be realized without unsuccessful surgical explorations, with a minimal early failure rate and a high maturation, even in patients with diabetes mellitus.

  16. Obstetrical complications in pregnant medical and surgical residents. (United States)

    Behbehani, Sadikah; Tulandi, Togas


    Objectif : Les résidentes enceintes sont exposées à des risques de complications obstétricales. Notre étude avait pour objectif d’évaluer l’incidence et le type des complications obstétricales constatées dans le cadre de la résidence, ainsi que leurs facteurs contributifs possibles. Méthodes : Nous avons mené une étude de cohorte rétrospective au moyen d’un questionnaire Web que nous avons fait parvenir à 190 programmes de résidence, tant en médecine qu’en chirurgie, de partout en Amérique du Nord. Ce questionnaire a été distribué à toutes les résidentes et nous avons demandé aux participantes de ne remplir le questionnaire que si elles avaient déjà connu une grossesse. Le questionnaire comptait 10 questions à choix multiple et était principalement axé sur les complications de grossesse auxquelles les résidentes pourraient avoir eu à faire face avant et pendant leur résidence. Les résultats ont été comparés à ceux qui ont été obtenus par 3 767 femmes enceintes d’âge semblable. Résultats : Le taux de complications obstétricales chez les résidentes qui étaient de garde pendant jusqu’à six nuits par mois (43/163 ou 26,4 %) était considérablement inférieur à celui des résidentes qui étaient de garde pendant plus de six nuits par mois (37/75 ou 49,3 %) (P grossesse, de décollement placentaire et de retard de croissance intra-utérin. Conclusion : La grossesse pendant la résidence compte un taux d’issues obstétricales indésirables plus élevé que la moyenne. Le fait de cumuler un plus grand nombre d’heures en salle d’opération et le fait d’être de garde pendant plus de six nuits par mois sont associés à des complications obstétricales. De surcroît, les résidentes enceintes sont plus susceptibles de connaître des troubles hypertensifs de la grossesse, un retard de croissance intra-utérin, un décollement placentaire et une fausse couche qu’une cohorte de femmes enceintes d’âge semblable.

  17. Sushruta: Foundation for Surgical Practice

    Directory of Open Access Journals (Sweden)

    Siddharth P. Dubhashi


    Full Text Available Sushruta was an ancient Indian surgeon (600 B.C. who resided in Varanasi.The teachings and work of Sushruta is compiled in a treatise called Sushruta Samhita (Sushruta's compendium, which is believed to be a part of Atharvaveda. It contains 184 chapters, descriptions of 1,120 illnesses, 300 surgical procedures, classification of human surgery in 8 categories, over 120 surgical instruments and around 700 drugs of animal, plant and mineral origin. Sushruta was one of the earliest exponents of surgery as an art and science. Sushruta's principles and teachings took surgery in ancient India to a noteworthy pedestal, making it the Golden Age of Surgery. He is truly the “Father of Surgery” and “Father of Plastic Surgery”. It is extremely essential that we put his principles into practice, and preserve the dignity of our noble profession. That would be the ideal tribute to this legendary figure.

  19. Surgical management of large scalp infantile hemangiomas

    Directory of Open Access Journals (Sweden)

    Imad S Khan


    Full Text Available Background: Infantile Hemangiomas (IH are the most common benign tumor of infancy, occurring in over 10% of newborns. While most IHs involute and never require intervention, some scalp IHs may cause severe cosmetic deformity and threaten tissue integrity that requires surgical excision. Case Description: We present our experience with two infants who presented with large scalp IH. After vascular imaging, the patients underwent surgical resection of the IH and primary wound closure with excellent cosmetic outcome. We detail the surgical management of these cases and review the relevant literature. Conclusion: In some cases the IHs leave behind fibro-fatty residuum causing contour deformity. Surgery is often required for very large lesions causing extensive anatomical and/or functional disruption. The goal of surgical intervention is to restore normal anatomic contour and shape while minimizing the size of the permanent scar.

  20. A Literature Review of Renal Surgical Anatomy and Surgical Strategies for Partial Nephrectomy (United States)

    Klatte, Tobias; Ficarra, Vincenzo; Gratzke, Christian; Kaouk, Jihad; Kutikov, Alexander; Macchi, Veronica; Mottrie, Alexandre; Porpiglia, Francesco; Porter, James; Rogers, Craig G.; Russo, Paul; Thompson, R. Houston; Uzzo, Robert G.; Wood, Christopher G.; Gill, Inderbir S.


    Context A detailed understanding of renal surgical anatomy is necessary to optimize preoperative planning and operative technique and provide a basis for improved outcomes. Objective To evaluate the literature regarding pertinent surgical anatomy of the kidney and related structures, nephrometry scoring systems, and current surgical strategies for partial nephrectomy (PN). Evidence acquisition A literature review was conducted. Evidence synthesis Surgical renal anatomy fundamentally impacts PN surgery. The renal artery divides into anterior and posterior divisions, from which approximately five segmental terminal arteries originate. The renal veins are not terminal. Variations in the vascular and lymphatic channels are common; thus, concurrent lymphadenectomy is not routinely indicated during PN for cT1 renal masses in the setting of clinically negative lymph nodes. Renal-protocol contrast-enhanced computed tomography or magnetic resonance imaging is used for standard imaging. Anatomy-based nephrometry scoring systems allow standardized academic reporting of tumor characteristics and predict PN outcomes (complications, remnant function, possibly histology). Anatomy-based novel surgical approaches may reduce ischemic time during PN; these include early unclamping, segmental clamping, tumor-specific clamping (zero ischemia), and unclamped PN. Cancer cure after PN relies on complete resection, which can be achieved by thin margins. Post-PN renal function is impacted by kidney quality, remnant quantity, and ischemia type and duration. Conclusions Surgical renal anatomy underpins imaging, nephrometry scoring systems, and vascular control techniques that reduce global renal ischemia and may impact post-PN function. A contemporary ideal PN excises the tumor with a thin negative margin, delicately secures the tumor bed to maximize vascularized remnant parenchyma, and minimizes global ischemia to the renal remnant with minimal complications.

  1. The importance of an ethics curriculum in surgical education. (United States)

    Keune, Jason D; Kodner, Ira J


    The nature of surgical work provides fertile ground in which ethical problems can grow. The concept of what it means to be a "good surgeon" includes the ability to reason and deliberate about how the surgeon's unique technical capabilities integrate with larger society. Ethics education at the resident level is important for several reasons. It can ensure that care is delivered in a socially and ethically responsible manner through global and emergent effects on institutions and traditions. It will prepare residents for leadership positions. It can allow residents to confront issues, such as the scientific underdetermination of surgical practice, the application of new technologies to trusting patients that have been developed by for-profit companies, and a surgical environment that is becoming increasingly institutionalized. Resident ethics education provides the opportunity for a model of collective deliberation to be developed that can be used to make sense of ethical problems as they arise.

  2. Medicare program; hospital inpatient prospective payment systems for acute care hospitals and the long-term care hospital prospective payment system and fiscal year 2013 rates; hospitals' resident caps for graduate medical education payment purposes; quality reporting requirements for specific providers and for ambulatory surgical centers. final rule. (United States)


    We are revising the Medicare hospital inpatient prospective payment systems (IPPS) for operating and capital-related costs of acute care hospitals to implement changes arising from our continuing experience with these systems. Some of the changes implement certain statutory provisions contained in the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (collectively known as the Affordable Care Act) and other legislation. These changes will be applicable to discharges occurring on or after October 1, 2012, unless otherwise specified in this final rule. We also are updating the rate-of-increase limits for certain hospitals excluded from the IPPS that are paid on a reasonable cost basis subject to these limits. The updated rate-of-increase limits will be effective for cost reporting periods beginning on or after October 1, 2012. We are updating the payment policies and the annual payment rates for the Medicare prospective payment system (PPS) for inpatient hospital services provided by long-term care hospitals (LTCHs) and implementing certain statutory changes made by the Affordable Care Act. Generally, these changes will be applicable to discharges occurring on or after October 1, 2012, unless otherwise specified in this final rule. In addition, we are implementing changes relating to determining a hospital's full-time equivalent (FTE) resident cap for the purpose of graduate medical education (GME) and indirect medical education (IME) payments. We are establishing new requirements or revised requirements for quality reporting by specific providers (acute care hospitals, PPS-exempt cancer hospitals, LTCHs, and inpatient psychiatric facilities (IPFs)) that are participating in Medicare. We also are establishing new administrative, data completeness, and extraordinary circumstance waivers or extension requests requirements, as well as a reconsideration process, for quality reporting by ambulatory surgical centers

  3. ACE up the sleeve - are vascular patients medically optimized?

    LENUS (Irish Health Repository)

    Coveney, A P


    To examine the current medical management of arteriopathic patients attending a vascular surgical service at a university teaching hospital over a 6-month period. The prescribing of antiplatelets, statins, angiotensin-converting enzyme (ACE) inhibitors, or angiotensin receptor blockers and beta-blockers was specifically examined. Vascular patients are often under the care of multiple specialties, and therefore the influence of different medical specialties on the patients\\' medical management was also examined.

  4. Self-evaluation: how well do surgery residents judge performance on a rotation? (United States)

    Gow, Kenneth W


    Surgical trainees are evaluated based on the Accreditation Council for Graduate Medical Education 6 core competencies. The ability for a learner to recognize strengths and weaknesses in these areas allows for critical self-improvement. Surgery residents rotating on a pediatric surgery rotation for 1 academic year were asked at an exit interview to provide a self-evaluation within the 6 core competencies on a Likert scale from 1 to 5. Self-evaluation scores were compared with a final group consensus attending evaluation. Further analyses included comparing residents as follows: less than R3 (junior residents) versus R3 (senior residents) residents, general surgery versus non-general surgery residents, university versus community residents, residents in the first half of the academic year versus residents in the second half, and top one third- and lowest one third-performing residents. Statistical analysis was performed using Student t tests with significance at P surgery residents, and highest one third-performing residents compared with junior residents, non-general surgery residents, and lowest one third-performing residents. There were no differences between self-evaluations and attending evaluations when comparing university with community residents and residents in the first half of the academic year with residents in the second half of the academic year. Residents appear to have a more critical self-analysis than attending surgeons, with senior residents, general surgery residents, and highest one third-performing residents being the most critical of their own performance. Poorly performing residents appeared to lack insight into their abilities. This method of self-evaluation helps trainees reflect on their performance and highlights trainees who lack self-awareness and need counseling for improvement. Copyright © 2013 Elsevier Inc.

    Stannard, A; Brown, K; Benson, C; Clasper, J; Midwinter, M; Tai, N R


    Military injuries to named blood vessels are complex limb- and life-threatening wounds that pose significant difficulties in prehospital and surgical management. The aim of this study was to provide a comprehensive description of the epidemiology, treatment and outcome of vascular injury among service personnel deployed on operations in Afghanistan and Iraq. Data from the British Joint Theatre Trauma Registry were combined with hospital records to review all cases of vascular trauma in deployed service personnel over a 5-year interval ending in January 2008. Of 1203 injured service personnel, 110 sustained injuries to named vessels; 66 of them died before any surgical intervention. All 25 patients who sustained an injury to a named vessel in the abdomen or thorax died; 24 did not survive to undergo surgery and one casualty in extremis underwent a thoracotomy, but died. Six of 17 patients with cervical vascular injuries survived to surgical intervention; two died after surgery. Of 76 patients with extremity vascular injuries, 37 survived to surgery with one postoperative death. Interventions on 38 limbs included 19 damage control procedures (15 primary amputations, 4 vessel ligations) and 19 definitive limb revascularization procedures (11 interposition vein grafts, 8 direct repairs), four of which failed necessitating three amputations. In operable patients with extremity injury, amputation or ligation is often required for damage control and preservation of life. Favourable limb salvage rates are achievable in casualties able to withstand revascularization. Despite marked progress in contemporary battlefield trauma care, torso vascular injury is usually not amenable to surgical intervention.

  8. Mentor-guided self-directed learning affects resident practice. (United States)

    Aho, Johnathon M; Ruparel, Raaj K; Graham, Elaina; Zendejas-Mummert, Benjamin; Heller, Stephanie F; Farley, David R; Bingener, Juliane


    Self-directed learning (SDL) can be as effective as instructor-led training. It employs less instructional resources and is potentially a more efficient educational approach. Although SDL is encouraged among residents in our surgical training program via 24-hour access to surgical task trainers and online modules, residents report that they seldom practice. We hypothesized that a mentor-guided SDL approach would improve practice habits among our residents. From 2011 to 2013, 12 postgraduate year (PGY)-2 general surgery residents participated in a 6-week minimally invasive surgery (MIS) rotation. At the start of the rotation, residents were asked to practice laparoscopic skills until they reached peak performance in at least 3 consecutive attempts at a task (individual proficiency). Trainees met with the staff surgeon at weeks 3 and 6 to evaluate progress and review a graph of their individual learning curve. All trainees subsequently completed a survey addressing their practice habits and suggestions for improvement of the curriculum. By the end of the rotation, 100% of participants improved in all practiced tasks (p < 0.05), and each reported that they practiced more in this rotation than during rotations without mentor-guided SDL. Additionally, 6 (50%) residents reported that their skill level had improved relative to their peers. Some residents (n = 3) felt that the curriculum could be improved by including task-specific goals and additional practice sessions with the staff surgeon. Mentor-guided SDL stimulated surgical residents to practice with greater frequency. This repeated deliberate practice led to significantly improved MIS skills without significantly increasing the need for faculty-led instruction. Some residents preferred more discrete goal setting and increased mentor guidance. Copyright © 2015 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

  9. Incidence and outcomes of intraoperative vascular surgery consultations. (United States)

    Danczyk, Rachel C; Coleman, Jake; Allensworth, Jordan; Azarbal, Amir F; Mitchell, Erica L; Liem, Timothy K; Landry, Gregory J; Moneta, Gregory L


    Vascular surgeons may aid in primarily nonvascular procedures. Such activity has not been quantified, and hospital administrators may be unaware of the importance of vascular surgeons to support other hospital-based surgical programs. This study reviewed intraoperative consultations by vascular surgeons to support other surgical services. Intraoperative vascular consultations were reviewed from January 2006 to January 2014 for consulting service, indication, and whether consultation occurred with advanced notice. Patient demographics, operative times, estimated blood loss, length of stay, and relative value units (RVUs) assigned for each consultation were also assessed. Consultations for trauma and iatrogenic injuries occurring outside the operating theater were excluded. Vascular surgeons performed 225 intraoperative consultations in support of procedures by nonvascular surgeons. Requesting services were surgical oncology (46%), orthopedics (17%), urology (11%), otolaryngology (7%), and others (19%). Reasons for consultation overlapped and included vascular reconstruction (53%), control of hemorrhage (39%), and assistance with difficult dissections (43%). Seventy-four percent were for intra-abdominal procedures, and venous (53%) and arterial (50%) problems were encountered equally with some overlap. Most patients were male (59%), overweight (56%; body mass index ≥25 kg/m(2)), had previous surgery (72%) and were undergoing elective procedures (89%). Mean total procedural anesthesia time was 9.4 hours, mean procedural operating time was 7.9 hours, and mean total and vascular-related estimated blood loss was 1702 mL and 327 mL, respectively. Mean length of stay was 14.7 days, mean intensive care unit stay was 2.9 days, and 30-day mortality was 6.2%. Mean nonvascular RVUs per operation were 46.0, and mean vascular RVUs per operation were 30.9. Unexpected intraoperative need for vascular surgical expertise occurs often enough that vascular surgeons should be regarded

  10. Impact of adding additional providers to resident workload and the resident experience on a medical consultation rotation. (United States)

    Fang, Michele; Linson, Eric; Suneja, Manish; Kuperman, Ethan F


    Excellence in Graduate Medical Education requires the right clinical environment with an appropriate workload where residents have enough patients to gain proficiency in medicine with optimal time for reflection. The Accreditation Council for Graduate Medical Education (ACGME) has focused more on work hours rather than workload; however, high resident workload has been associated with lower resident participation in education and fatigue-related errors. Recognizing the potential risks associated with high resident workload and being mindful of the costs of reducing resident workload, we sought to reduce residents' workload by adding an advanced practice provider (APP) to the surgical comanagement service (SCM) and study its effect on resident satisfaction and perceived educational value of the rotation. In Fiscal Year (FY) 2014 and 2015, an additional faculty member was added to the SCM rotation. In FY 2014, the faculty member was a staff physician, and in FY 2015, the faculty member was an APP.. Resident workload was assessed using billing data. We measured residents' perceptions of the rotation using an anonymous electronic survey tool. We compared FY2014-2015 data to the baseline FY2013. The number of patients seen per resident per day decreased from 8.0(SD 3.3) in FY2013 to 5.0(SD 1.9) in FY2014 (p rotation (40.0%, 72.2%, 72.6% in FY2013, 2014, 2015 respectively, p rotation.

  11. Surgical management of moyamoya disease: a review. (United States)

    Baaj, Ali A; Agazzi, Siviero; Sayed, Zafar A; Toledo, Maria; Spetzler, Robert F; van Loveren, Harry


    Moyamoya disease (MMD) is a progressive, occlusive disease of the distal internal carotid arteries associated with secondary stenosis of the circle of Willis. Symptoms include ischemic infarcts in children and hemorrhages in adults. Bypass of the stenotic vessel(s) is the primary surgical treatment modality for MMD. Superficial temporal artery-to-middle cerebral artery bypass is the most common direct bypass method. Indirect techniques rely on the approximation of vascularized tissue to the cerebral cortex to promote neoangiogenesis. This tissue may be in the form of muscle, pericranium, dura, or even omentum. This review highlights the surgical options available for the treatment of MMD.

  12. Aldosterone and vascular damage. (United States)

    Duprez, D; De Buyzere, M; Rietzschel, E R; Clement, D L


    Although the aldosterone escape mechanism is well known, aldosterone has often been neglected in the pathophysiologic consequences of the activated renin-angiotensin-aldosterone system in arterial hypertension and chronic heart failure. There is now evidence for vascular synthesis of aldosterone aside from its secretion by the adrenal cortex. Moreover, aldosterone is involved in vascular smooth muscle cell hypertrophy and hyperplasia, as well as in vascular matrix impairment and endothelial dysfunction. The mechanisms of action of aldosterone may be either delayed (genomic) or rapid (nongenomic). Deleterious effects of aldosterone leading to vascular target-organ damage include (besides salt and water retention) decreased arterial and venous compliance, increased peripheral vascular resistance, and impaired autonomic vascular control due to baroreflex dysfunction.

    Chiapponi, Costanza; Meyer, Christine Y; Heinemann, Silvia; Meyer, Frank; Biberthaler, Peter; Bruns, Christiane J; Kanz, Karl-Georg

    Working conditions in hospitals generate stress within all professional groups. The aim of this study was to find out how German medical students during their senior student clerkship in surgery perceive their own stress and the stress of surgical residents. This was measured using "Instrument zur stressbezogenen Arbeitsanalyse bei KlinikÃrztInnen (ISAK-K)," a validated questionnaire of the German statutory occupational accident insurance system (BGW). This bi-institutional paper-and-pencil survey was performed on 52 medical students in their sixth year, who had been working in a surgical department for 4 months. Data were compared with those of the BGW on the stress perceived by physicians working in German surgical departments. The stress levels measured with the ISAK-K were similar in students and in physicians working in surgery. Students believe that surgical residents experience a higher time pressure (p students planning a surgical career feel to be more exposed to time pressure (p students, students interested in surgery believe that surgical residents have more possibilities to learn at work (p students believe that surgical residents commonly need to take decisions without having enough information (p students overestimate the stress of surgical residents. Students overestimate time pressure and uncertainty of surgical residents. A possible way to increase their interest in surgery is offering a better insight in surgeons' work and strategies to deal with these stressors.

    U.S. black and Hispanic populations are growing at a steady pace. In contrast, the medical profession lacks the same minority growth and representation. Women are also under-represented in many surgical disciplines. The purpose of this study was to assess trends in the proportion of women, blacks, and Hispanics admitted to vascular surgery (VS) and related specialties, and to compare them with each other and with a surgical specialty, orthopedic surgery (OS), with a formal diversity initiative. Data on the fellowship pool of VS, interventional radiology (IR), and interventional cardiology (IC), as well as the resident pools of general surgery (GS) and orthopedic surgery (OS), were obtained from U.S. graduate medical education reports for 1999 through 2005. Cochrane-Armitage trend tests were used to assess trends in the proportion of females, blacks, and Hispanics in relation to the total physician workforce for each subspecialty. No significant trends in the proportion of females, blacks, or Hispanics accepted into VS and IC fellowship programs occurred during the study period. In contrast, IR, GS, and OS programs revealed significant trends for increasing proportions of at least one of the underrepresented study groups. In particular, OS, which has implemented a diversity awareness program, showed a positive trend in female and Hispanic trainees (P workforce diversity.

  15. Quantification of Hepatic Vascular and Parenchymal Regeneration in Mice (United States)

    Xie, Chichi; Schwen, Lars Ole; Wei, Weiwei; Schenk, Andrea; Zafarnia, Sara; Gremse, Felix; Dahmen, Uta


    Background Liver regeneration consists of cellular proliferation leading to parenchymal and vascular growth. This study complements previous studies on cellular proliferation and weight recovery by (1) quantitatively describing parenchymal and vascular regeneration, and (2) determining their relationship. Both together are needed to (3) characterize the underlying growth pattern. Methods Specimens were created by injecting a polymerizing contrast agent in either portal or hepatic vein in normal or regenerating livers after 70% partial hepatectomy. 3D image data were obtained through micro-CT scanning. Parenchymal growth was assessed by determining weight and volume of the regenerating liver. Vascular growth was described by manually determined circumscribed parameters (maximal vessel length and radius of right inferior portal/hepatic vein), automatically determined cumulative parameters (total edge length and total vascular volume), and parameters describing vascular density (total edge length/volume, vascular volume fraction). The growth pattern was explored by comparing the relative increase of these parameters to the increase expected in case of isotropic expansion. Results Liver volume recovery paralleled weight recovery and reached 90% of the original liver volume within 7 days. Comparing radius-related vascular parameters immediately after surgical resection and after virtual resection in-silico revealed a slight increase, possibly reflecting the effect of resection-induced portal hyperperfusion. Comparing length-related parameters between post-operative day 7 and after virtual resection showed similar vascular growth in both vascular systems investigated. In contrast, radius-related parameters increased slightly more in the portal vein. Despite the seemingly homogeneous 3D growth, the observed vascular parameters were not compatible with the hypothesis of isotropic expansion of liver parenchyma and vascular structures. Conclusion We present an approach for

  16. High Disparity Between Orthopedic Resident Interest and Participation in International Health Electives. (United States)

    Zhang, Steven; Shultz, Paul; Daniels, Alan; Ackelman, Edward; Kamal, Robin N


    Few orthopedic surgical residency programs offer international health electives (IHEs). Efforts to expand these programs have been increasing across medical disciplines. Whether orthopedic residents will participate remains unknown. This study quantified and characterized orthopedic resident interest and barriers to IHEs in US residency programs. A web-based survey was administered to residents from 154 US orthopedic residency programs accredited by the Accreditation Council for Graduate Medical Education 2014 to 2015. Questions assessed demographics and program background, previous medical experience abroad, barriers to participation, and level of interest in participating in an international health elective during their training and beyond. Twenty-seven (17.5%) residency programs responded. Chi-square analysis showed that residents who expressed interest in participating were significantly more likely to have experience abroad compared with those who expressed no interest (Porthopedic residencies (POrthopedics. 2016; 39(4):e680-e686.].

    Exposition of results obtained from the review of the surgical complications found in a series of 479 renal transplantations performed between 1978 and 1992 in our centre, although some of them lack clinical relevance. There was fluid accumulation in 69 patients, distributed between 31 perirenal haematoma. 17 lymphocele, 13 urinoma, 5 perirenal abscesses and 3 mixed. 27.7% required no action. Frequency of renal rupture was 18 cases, 9 due to acute rejection and 9 to vascular thrombosis. Incidence of urinary obstruction was 4.8% with 5.8% of urinary fistula. With regard to the surgical wound, 9 infections, 7 haematomas, 1 eventration and 1 necrotizing fasciitis were observed. Vascular complications consisted in 10 arterial thrombosis, 10 venous thrombosis, 5 mixed thrombosis and 31 arterial stenosis. Treatment instituted for the various cases, its evolution, and an statistical study of risk factors are illustrated.

    Full Text Available Medical residents, as part of their job to balance the demands of their work with caring for themselves so as to be mentally, emotionally, and physically sound to stay clinically competent. While regulatory and legislative attempts at limiting medical resident work hours have materialized but have yet to attain passage, there are fairly little data looking into how residents cope up with their demands and yet attend to their own personal health.Anonymous mailed survey.Three hundred and thirty-seven residents from all internal medicine residency programs within United States.We conducted a survey in the form of a questionnaire that was sent by e-mail to the program directors of various internal medicine residency programs within the United States, and responses were collected between May 19 and June 21, 2009. Response was well appreciated with total number of participants of 337 with even demographical distribution in gender, residency year, AMG/IMG, age group. Seventy-one percent of the residents felt that they would prefer getting admitted to their own hospital for any acute medical or surgical condition. Of the 216 residents who have had received health care in the past, almost half of them chose their own hospital because of the proximity, while 45% did not choose their own hospital despite proximity. Two out of three residents missed their doctors appointments or cancelled them due to demands of medical training. Only half of the residents have a primary care physician and almost 80% of them did not have their yearly health checkup. Close to 30% held back information regarding their social and sexual history from their provider because of privacy and confidentiality concerns. Eighty percent of residents never received information about barriers that physicians may face in obtaining care for their socially embarrassing conditions. Seventy percent felt that their performance then was suboptimal because of that health condition and also felt

  19. Vascular Cognitive Impairment. (United States)

    Dichgans, Martin; Leys, Didier


    Cerebrovascular disease typically manifests with stroke, cognitive impairment, or both. Vascular cognitive impairment refers to all forms of cognitive disorder associated with cerebrovascular disease, regardless of the specific mechanisms involved. It encompasses the full range of cognitive deficits from mild cognitive impairment to dementia. In principle, any of the multiple causes of clinical stroke can cause vascular cognitive impairment. Recent work further highlights a role of microinfarcts, microhemorrhages, strategic white matter tracts, loss of microstructural tissue integrity, and secondary neurodegeneration. Vascular brain injury results in loss of structural and functional connectivity and, hence, compromise of functional networks within the brain. Vascular cognitive impairment is common both after stroke and in stroke-free individuals presenting to dementia clinics, and vascular pathology frequently coexists with neurodegenerative pathology, resulting in mixed forms of mild cognitive impairment or dementia. Vascular dementia is now recognized as the second most common form of dementia after Alzheimer's disease, and there is increasing awareness that targeting vascular risk may help to prevent dementia, even of the Alzheimer type. Recent advances in neuroimaging, neuropathology, epidemiology, and genetics have led to a deeper understanding of how vascular disease affects cognition. These new findings provide an opportunity for the present reappraisal of vascular cognitive impairment. We further briefly address current therapeutic concepts.

    Intraosseous vascular lesions of the maxillofacial region are rare, and the differential diagnosis of intraosseous vascular malformations from other jaw lesions can be challenging. In the present case, magnetic resonance imaging and three-dimensional computed tomographic angiography (CTA) was used for diagnosis, and the lesion was treated with surgical excision. Diverse characteristics such as the 'honeycomb' and 'sunburst' radiographic appearances and the absence of major peripheral feeder vessels in the CTA were noted. Intraosseous vascular malformations have a varied radiographic appearance, and the nomenclature of these lesions is equally diverse, with several overlapping terms. Pathologists do not generally differentiate among intraosseous vascular lesions on the basis of histopathology, although these lesions may present with contrasting immunohistochemical and clinical behaviors requiring varied treatment strategies. This case report highlights the need for multiple imaging modalities to differentiate among vascular lesions, as well as to better understand the behaviors of these unique lesions.

  2. The General Surgery Chief Resident Operative Experience (United States)

    Drake, Frederick Thurston; Horvath, Karen D.; Goldin, Adam B.; Gow, Kenneth W.


    IMPORTANCE The chief resident (CR) year is a pivotal experience in surgical training. Changes in case volume and diversity may impact the educational quality of this important year. OBJECTIVE To evaluate changes in operative experience for general surgery CRs. DESIGN, SETTING, AND PARTICIPANTS Review of Accreditation Council for Graduate Medical Education case logs from 1989–1990 through 2011–2012 divided into 5 periods. Graduates in period 3 were the last to train with unrestricted work hours; those in period 4 were part of a transition period and trained under both systems; and those in period 5 trained fully under the 80-hour work week. Diversity of cases was assessed based on Accreditation Council for Graduate Medical Education defined categories. MAIN OUTCOMES AND MEASURES Total cases and defined categories were evaluated for changes over time. RESULTS The average total CR case numbers have fallen (271 in period 1 vs 242 in period 5, P surgery training may be jeopardized by reduced case diversity. Chief resident cases are crucial in surgical training and educators should consider these findings as surgical training evolves. PMID:23864049

    To design an orientation for surgical interns to meet the new Accreditation Council for Graduate Medical Education Common Program Requirements regarding supervision, to test patient-management competencies, and to assess confidence on skills and tasks pre-orientation and post-orientation. Twenty-seven incoming surgical interns participated in a two-day orientation to clinical duties. Activities included a pre-test, lectures, simulation, oral examination, intern shadowing, and a post-test. Incoming interns were surveyed before and after orientation and two months later for confidence in patient-management and surgical intern skills. Paired t-tests were used to determine if confidence improved pre-orientation and post-orientation, and two months following orientation. The study took place at an academic training hospital. All (n = 27) postgraduate year-1 (PGY-1) surgical residents at our institution, which included the categorical and nondesignated preliminary general surgery, urology, orthopedic surgery, otolaryngology, and neurosurgery programs. All interns passed the oral and written examinations, and were deemed able to be indirectly supervised, with direct supervision immediately available. They reported increased confidence in all areas of patient management addressed during orientation, and this confidence was retained after two months. In surgical and floor-related tasks and skills, interns reported no increase in confidence directly following orientation. However, after two months, they reported a significant increase in confidence, particularly in those tasks that are performed often. New requirements for resident supervision require creative ways of verifying resident competency in basic skills. This type of orientation is an effective way to address the new requirements of supervision and teach interns the tasks and skills that are necessary for internship.

  4. Surgical treatment of complicated traumatic aneurysm and arteriovenous fistula

    Institute of Scientific and Technical Information of China (English)

    乔正荣; 时德


    Objective: To evaluate the surgical methods and the outcome of management for traumatic arterial aneurysm (TAA) and traumatic arteriovenous fistula (TAVF). Methods: A total of 121 patients with TAA or TAVF were treated by surgery. Clinical, operative and postoperative data were collected and analyzed retrospectively. Results: The surgical techniques included aneurysmectomy and arterial end-to-end anastomosis or vascular grafting or artery ligation, aneurysm ligation and bypass, vascular repair, fistula excision and vascular ligation or vascular grafting or repair and so on. One patient died (0.83%). The follow-up rates of TAA and TAVF were 65.7% and 60% respectively. Conclusions: Complicated TAA and TAVF in different sites should be treated with different methods.

  5. Large vascular malformation in a child presenting with vascular steal phenomenon managed with pial synangiosis. (United States)

    Ellis, Michael J; Armstrong, Derek; Dirks, Peter B


    The management of large and giant arteriovenous malformations (AVMs) in patients presenting with nonhemorrhagic neurological deficits secondary to vascular steal phenomenon is challenging and controversial. In many cases, large AVMs cannot be completely excised or cured, leaving patients with residual or partially treated AVMs, the natural history of which is unknown. Additionally, large, diffuse vascular malformations with multiple, small feeders, slow flow, or so-called cerebral proliferative angiopathy represent a related but distinct clinical and angiographic entity that may require a different therapeutic approach than traditional brain AVMs. The current management of children with other conditions of chronic cerebral hypoperfusion, such as moyamoya disease, involves consideration of surgical revascularization to enhance blood flow to the compromised hemisphere. Here, the authors present the case of a young child with a large thalamic vascular malformation who presented with clinical and radiological features of vascular steal and ischemia. In an effort to augment flow to the hypoperfused brain and protect against future ischemia, the authors treated the child with unilateral pial synangiosis. At 12 months, postoperative angiography demonstrated robust neovascularization, and the child has not sustained any further ischemic events. The authors discuss concept of vascular malformation-related hypoperfusion and the utility of indirect revascularization for inoperable vascular malformations presenting with ischemic symptoms.

  6. Micro-surgical endodontics. (United States)

    Eliyas, S; Vere, J; Ali, Z; Harris, I


    Non-surgical endodontic retreatment is the treatment of choice for endodontically treated teeth with recurrent or residual disease in the majority of cases. In some cases, surgical endodontic treatment is indicated. Successful micro-surgical endodontic treatment depends on the accuracy of diagnosis, appropriate case selection, the quality of the surgical skills, and the application of the most appropriate haemostatic agents and biomaterials. This article describes the armamentarium and technical procedures involved in performing micro-surgical endodontics to a high standard.

  7. Surgical innovation as sui generis surgical research. (United States)

    Lotz, Mianna


    Successful innovative 'leaps' in surgical technique have the potential to contribute exponentially to surgical advancement, and thereby to improved health outcomes for patients. Such innovative leaps often occur relatively spontaneously, without substantial forethought, planning, or preparation. This feature of surgical innovation raises special challenges for ensuring sufficient evaluation and regulatory oversight of new interventions that have not been the subject of controlled investigatory exploration and review. It is this feature in particular that makes early-stage surgical innovation especially resistant to classification as 'research', with all of the attendant methodological and ethical obligations--of planning, regulation, monitoring, reporting, and publication--associated with such a classification. This paper proposes conceptual and ethical grounds for a restricted definition according to which innovation in surgical technique is classified as a form of sui generis surgical 'research', where the explicit goal of adopting such a definition is to bring about needed improvements in knowledge transfer and thereby benefit current and future patients.

  8. Surgical Reconstruction for Severe Tracheal Obstruction in Morquio A Syndrome. (United States)

    Pizarro, Christian; Davies, Ryan R; Theroux, Mary; Spurrier, Ellen A; Averill, Lauren W; Tomatsu, Shunji


    Progressive tracheal obstruction is commonly seen in Morquio A syndrome and can lead to life-threatening complications. Although tracheostomy can address severe upper airway obstruction, lower airway obstruction, commonly associated with a narrow thoracic inlet and vascular compression, requires an alternative approach. We describe the case of a 16-year-old patient with Morquio A syndrome whose near-fatal tracheal obstruction was relieved by timely surgical tracheal vascular reconstruction with dramatic resolution of his respiratory symptoms.

    Vries, Harry de


    General introduction Carcinoids are rare slowly growing, neuroendocrine tumors. In 1907 Obendorfer was the first to use the term carcinoid (Karzinoide)1. He described an ileal tumor with a much slower progression than expected from denocarcinomas. The traditional classification of the carcinoids acc

    Turgut, Namigar; Karacalar, Serap; Polat, Cengiz; Kıran, Özlem; Gültop, Fethi; Kalyon, Seray Türkmen; Sinoğlu, Betül; Zincirci, Mehmet; Kaya, Ender


    The aim of this study is identified the degree of Burnout Syndrome (BOS) and find out its correlation with years of recidency and sociodemograpfic chareacteristics, training, sleeping habits, such as smoking and alcohol consumption. After approval from the Hospital Ethics Committee and obtaining informed consent, First, second, third, fourth and fifth year of recidency staff (n=127) working in our hospital were involved in this study. The standardized Maslach Burnout Inventory (MBI) was used in this study. Fifty six male (44.1%) and seventy one female (55.9%) residents were enroled in this study (Coranbach Alfa(α)=0.873). 57% of the first year residents smokes cigaret and 54% of them use alcohol. 2% of them gets one day off after hospital night shift, 61% of them suffers from disturbed sleep. 60% of them had been stated that they willingly selected their profession. 61% of them prefers talking to friends and 32% of them prefers shopping to overcome stress. There were statistical difference acording to years of recidency in MBI, Emotional Burnout (EB) and desensitisation scale (DS) points. EB scale points of the second year of residency group was statisticaly higher than fourth year of residency group. DS points of second year of residency group was also statisticaly higher than the third and fourth year of residency group. There was no statistical difference between any groups in Personal Success. BOS is a frequent problem during residency in anaesthesia. Appropriate definition and awareness are the first important steps to prevent this syndrome. Further administrative approaches should be evaluated with regard to their effects.

  15. Comparative characterization of stromal vascular cells derived from three types of vascular wall and adipose tissue. (United States)

    Yang, Santsun; Eto, Hitomi; Kato, Harunosuke; Doi, Kentaro; Kuno, Shinichiro; Kinoshita, Kahori; Ma, Hsu; Tsai, Chi-Han; Chou, Wan-Ting; Yoshimura, Kotaro


    Multipotent stem/progenitor cells localize perivascularly in many organs and vessel walls. These tissue-resident stem/progenitor cells differentiate into vascular endothelial cells, pericytes, and other mesenchymal lineages, and participate in physiological maintenance and repair of vasculatures. In this study, we characterized stromal vascular cells obtained through the explant culture method from three different vessel walls in humans: arterial wall (ART; >500 μm in diameter), venous wall (VN; >500 μm in diameter), and small vessels in adipose tissue (SV; arterioles and venules, adipose-derived stem/stromal cells (ASCs). All stromal vascular cells of different origins presented fibroblast-like morphology and we could not visually discriminate one population from another. Flow cytometry showed that the cultured population heterogeneously expressed a variety of surface antigens associated with stem/progenitor cells, but CD105 was expressed by most cells in all groups, suggesting that the cells generally shared the characteristics of mesenchymal stem cells. Our histological and flow cytometric data suggested that the main population of vessel wall-derived stromal vascular cells were CD34(+)/CD31(-) and came from the tunica adventitia and areola tissue surrounding the adventitia. CD271 (p75NTR) was expressed by the vasa vasorum in the VN adventitia and by a limited population in the adventitia of SV. All three populations differentiated into multiple lineages as did ASCs. ART cells induced the largest quantity of calcium formation in the osteogenic medium, whereas ASCs showed the greatest adipogenic differentiation. SV and VN stromal cells had greater potency for network formation than did ART stromal cells. In conclusion, the three stromal vascular populations exhibited differential functional properties. Our results have clinical implications for vascular diseases such as arterial wall calcification and possible applications to regenerative therapies

  16. Adoption of information technology by resident physicians. (United States)

    Parekh, Selene G; Nazarian, David G; Lim, Charles K


    The Internet represents a technological revolution that is transforming our society. In the healthcare industry, physicians have been typified as slow adopters of information technology. However, young physicians, having been raised in a computer-prevalent society, may be more likely to embrace technology. We attempt to characterize the use and acceptance of the Internet and information technology among resident physicians in a large academic medical center and to assess concerns regarding privacy, security, and credibility of information on the Internet. A 41-question survey was distributed to 150 pediatric, medical, and surgical residents at an urban, academic medical center. One hundred thirty-five residents completed the survey (response rate of 90%). Responses were evaluated and statistical analysis was done. The majority of resident physicians in our survey have adopted the tools of information technology. Ninety-eight percent used the Internet and 96% use e-mail. Two-thirds of the respondents used the Internet for healthcare-related purposes and a similar percentage thought that the Internet has affected their practice of medicine positively. The majority of residents thought that Internet healthcare services such as electronic medical records, peer-support websites, and remote patient monitoring would be beneficial for the healthcare industry. However, they are concerned about the credibility, privacy, and security of health and medical information online. The majority of resident physicians in our institution use Internet and information technology in their practice of medicine. Most think that the Internet will continue to have a beneficial role in the healthcare industry.

  17. [Vascular factors in glaucoma]. (United States)

    Mottet, B; Aptel, F; Geiser, M; Romanet, J P; Chiquet, C


    The exact pathophysiology of glaucoma is not fully understood. Understanding of the vascular pathophysiology of glaucoma requires: knowing the techniques for measuring ocular blood flow and characterizing the topography of vascular disease and the mechanisms involved in this neuropathy. A decreased mean ocular perfusion pressure and a loss of vascular autoregulation are implicated in glaucomatous disease. Early decrease in ocular blood flow has been identified in primary open-angle glaucoma and normal pressure glaucoma, contributing to the progression of optic neuropathy. The vascular damage associated with glaucoma is present in various vascular territories within the eye (from the ophthalmic artery to the retina) and is characterized by a decrease in basal blood flow associated with a dysfunction of vasoregulation.

  18. Increasing Trends in Orthopedic Fellowships Are Not due to Inadequate Residency Training

    Directory of Open Access Journals (Sweden)

    K. A. Almansoori


    Full Text Available Orthopedic residents have one of the highest fellowship participation rates among medical specialities and there are growing concerns that inadequate residency training may be contributing to this trend. Therefore, a mixed-exploratory research survey was distributed to all 148 graduating Canadian orthopedic residents to investigate their perceptions and attitudes for pursuing fellowships. A response rate of 33% (n=49 was obtained with the majority of residents undertaking one (27% or two (60% fellowships. Surgical-skill development was reported as the most common motivating factor, followed by employment and marketability; malpractice protection and financial reasons were the least relevant. The overwhelming majority of residents (94%, n=46 felt adequately prepared by their residency training for independent general practice, and 84% (n=41 of respondents did not feel that current fellowship trends were due to poor residency training. Three common themes were expressed in their comments: the growing perceived expectation by healthcare professionals and employers to be fellowship-certified, the integration of fellowship training into the surgical education hierarchy, and the failure of residency training curriculums to accommodate for this trend. In conclusion, Canadian orthopedic residents are confident of their residency training and are increasingly pursuing fellowships to primarily develop their surgical skills and expertise.

  19. Surgical Treatment of Skin Tumors

    Directory of Open Access Journals (Sweden)



    Full Text Available When we mention about surgical treatment of any tumor residing on the skin independent of its benign or malignant nature, the first method we recall is excision. Elliptical excision is the mainstay of the dermatologic surgery. Each excision ends with a defect for which we are responsible to repair functionally and cosmetically. The diameter of the tumor we excised and the safety margin used for excision determine the diameter of the final defect. After achieving tumor free lateral and deep margins with the appropriate surgical method, we decide between the repair options of second intention healing, primary repair, flaps, full or split thickness grafts, considering the diameter and the anatomic localization of the defect, for the best functional and cosmetic result for that specific defect. This review overviews not only the most common dermatologic surgical methods, but also Mohs surgery which is a method rarely used in our country, although it is the treatment of choice for the treatment of high risk basal cell carcinoma (BCC and squamous cell carcinoma (SCC.

  20. Simulation in cardiology and cardiothoracic and vascular surgery. (United States)

    Lake, Carol L


    Cardiologists and cardiac surgeons are rapidly embracing the use of realistic patient simulators and virtual reality devices to allow mastery of complex techniques, planning of complicated procedures, crisis management of infrequently seen diseases and complications, and development of medical team work. Simulation can certainly be used for these purposes in surgical education but provides only the ;;tip of the iceberg'' of the knowledge needed by the competent cardiothoracic, vascular, or general surgeon. Is simulation really the way to learn how to perform actual surgical procedures? This review will describe available surgical simulation technology, and define some of the problems to be solved for validation and general acceptance.

    Klein, Eileen J; Jackson, J Craig; Kratz, Lyn; Marcuse, Edgar K; McPhillips, Heather A; Shugerman, Richard P; Watkins, Sandra; Stapleton, F Bruder


    The need to teach professionalism during residency has been affirmed by the Accreditation Council for Graduate Medical Education, which will require documentation of education and evaluation of professionalism by 2007. Recently the American Academy of Pediatrics has proposed the following components of professionalism be taught and measured: honesty/integrity, reliability/responsibility, respect for others, compassion/empathy, self-improvement, self-awareness/knowledge of limits, communication/collaboration, and altruism/advocacy. The authors describe a curriculum for introducing the above principles of professionalism into a pediatrics residency that could serve as a model for other programs. The curriculum is taught at an annual five-day retreat for interns, with 11 mandatory sessions devoted to addressing key professionalism issues. The authors also explain how the retreat is evaluated and how the retreat's topics are revisited during the residency, and discuss general issues of teaching and evaluating professionalism.

  3. Surgical technique refinements in head and neck oncologic surgery. (United States)

    Liu, Jeffrey C; Shah, Jatin P


    The head and neck region poses a challenging arena for oncologic surgery. Diseases and their treatment can affect a myriad of functions, including sight, hearing, taste, smell, breathing, speaking, swallowing, facial expression, and appearance. This review discusses several areas where refinements in surgical techniques have led to improved patient outcomes. This includes surgical incisions, neck lymphadenectomy, transoral laser microsurgery, minimally invasive thyroid surgery, and the use of vascularized free flaps for oromandibular reconstruction.

  4. Surgical options in ICH including decompressive craniectomy. (United States)

    Mitchell, Patrick; Gregson, Barbara A; Vindlacheruvu, Raghu R; Mendelow, A David


    Intracerebral haemorrhage (ICH) accounts for 15 to 20% of strokes. The condition carries a higher morbidity and mortality than occlusive stroke. Despite considerable research effort, no therapeutic modality either medical or surgical has emerged with clear evidence of benefit other than in rare aneurysmal cases. Intracerebral haemorrhages can be divided into those that arise from pre-existing macroscopic vascular lesions - so called "ictohaemorrhagic lesions", and those that do not; the latter being the commoner. Most of the research that has been done on the benefits of surgery has been in this latter group. Trial data available to date precludes a major benefit from surgical evacuation in a large proportion of cases however there are hypotheses of benefit still under investigation, specifically superficial lobar ICH treated by open surgical evacuation, deeper ICH treated with minimally invasive surgical techniques, and decompressive craniectomy. When an ICH arises from an ictohaemorrhagic lesion, therapy has two goals: to treat the effects of the acute haemorrhage and to prevent a recurrence. Three modalities are available for treating lesions to prevent recurrence: stereotactic radiosurgery, endovascular embolisation, and open surgical resection. As with ICH without an underlying lesion there is no evidence to support surgical removal of the haemorrhage in most cases. An important exception is ICHs arising from intracranial aneurysms where there is good evidence to support evacuation of the haematoma as well as repair of the aneurysm.

    Full Text Available Adam EM Eltorai Warren Alpert Medical School of Brown University, RI, USA Abstract: Obesity is a major public health concern. Given its lasting efficacy for improving obesity and obesity-related diseases, bariatric surgery is an increasingly common treatment option. As the implementation of the Affordable Care Act progresses, the impending physician shortage will become more severe. Thus there will be an even greater need for doctors specialized in the management and treatment of obese patients.

  6. Development and implementation of a formalized geriatric surgery curriculum for general surgery residents. (United States)

    Barbas, Andrew S; Haney, John C; Henry, Brandon V; Heflin, Mitchell T; Lagoo, Sandhya A


    Despite the growth of the elderly population, most surgical training programs lack formalized geriatric education. The authors' aim was to implement a formalized geriatric surgery curriculum at an academic medical center. Surgery residents were surveyed on attitudes toward the care of elderly patients and the importance of various geriatric topics to daily practice. A curriculum consisting of 16 didactic sessions was created with faculty experts moderating. After curriculum completion, residents were surveyed to assess curriculum impact. Residents expressed increased comfort in accessing community resources. A greater percentage of residents recognized the significance of delirium and acute renal failure in elderly patients. Implementing a geriatric surgery curriculum geared toward surgery residents is feasible and can increase resident comfort with multidisciplinary care and recognition of clinical conditions pertinent to elderly surgical patients. This initiative also provided valuable experience for geriatric surgery curriculum development.

  7. Changes in residents' opportunities for experiential learning over time. (United States)

    Peets, Adam D; Stelfox, Henry T


    Learning in the clinical environment is believed to be a crucial component of residency training. However, it remains unclear whether recent changes to postgraduate medical education, including the implementation of work hour limitations, have significantly impacted opportunities for experiential learning. Therefore, we sought to quantify opportunities to gain clinical experience within medical-surgical intensive care units (ICUs) over time. Data on the numbers of patients admitted and invasive procedures performed per day between 1 July 2001 and 30 June 2010 within three academic medical-surgical ICUs in Calgary, Alberta, Canada were obtained from electronic medical records. These data were matched to resident doctor on-call schedules and residents' opportunities to admit patients and participate in procedures were calculated and compared over time using Spearman's rho. We found that over a 9-year period, the opportunities afforded to residents (n = 1156) to admit patients (n = 17 189) and perform procedures (n = 52 827) during ICU rotations decreased by 32% (p < 0.001) and 34% (p < 0.001), respectively. Our results suggest that there has been a significant decrease in residents' clinical experiences in the ICU over time. Further investigations to better understand these changes and how they may impact on performance as residents become independent practising doctors are warranted. © Blackwell Publishing Ltd 2012.

  8. An obstetrics and gynaecology graduate residency programme in Venezuela. (United States)

    Faneite, P.


    We present our experience on the design and development of a gynaecology and obstetrics graduate residency programme, developed in the Department of Obstetrics and Gynecology at the Dr Adolfo Prince Lara Hospital, Puerto Cabello, Venezuela, in which medical specialists and residents participate synergistically. From January to September 1993, curricular activities were planned and students selected. The programme started in October 1993, with six residents for a three-year programme. Courses were given by medical specialists from the Department. In addition to a Programme Coordinator, there is also a Residents' Coordinator, appointed for a two-month term of office; specific functions were assigned for residents occupying this position. All the programmed activities for three years were accomplished, including lectures and rotations, with an important record of surgical interventions. In our grade system, residents got an average of 18 over a maximum of 20 points. Residents also participated as speakers in workshops, special courses and national medicinal meetings, in which they presented a total of nine papers. Activities were evaluated bimonthly in meetings with students and each semester by the Graduate Committee. The first class graduated in September 1996. Results suggest that resident participation in graduate programmes is an important part of their education. PMID:9538482

  9. [General surgery under discussion. From the viewpoint of vascular surgery]. (United States)

    Debus, E S; Eckstein, H H; Böckler, D; Imig, H; Florek, A


    Vascular diseases are common and their frequency is rising. Statistics show that 15% of the German population over 65 display some kind of peripheral arterial pathology. Even aneurysmatic degeneration and cardiac and visceral perfusion disorders are being observed more frequently, while peak age is dropping. Therapeutic surgical options are accordingly being continually advanced and refined. Additionally the range of interventional therapies and new conservative options has substantially increased vascular surgeons' armamentarium. Updates in surgical training have responded to this increase in such disorders, and the diversification of therapeutic modalities has resulted in the elevation of vascular surgery from specialized techniques to a fully accredited specialty equal in standing to the other seven surgical disciplines. Controversy exists however about the new accredition, beginning with the question of advancement from basic surgical training while excluding important elements of general surgery. Since those training for this specialty will branch off immediately after 2 years of basic surgical training, their final accreditation in the new classification would exclude essential skills that remain part of the training as general surgeons.

  10. Financial debt of orthopedic residents. (United States)

    Hwang, John S; Beebe, Kathleen S; Benevenia, Joseph; Karanfilian, Briette; Berberian, Wayne S


    Many orthopedic residents accrue considerable debt by residency graduation. These debts for graduating medical students continue to increase due to the yearly increase of medical school tuition. The purpose of this study was to examine the causes of financial debt, as well the effects of debt on orthopedic residents.Orthopedic residents from postgraduate years 1 to 5 (N=27) completed an anonymous, optional financial survey. The survey asked questions regarding the characteristics of the residents' debt and their concern caused by their debt. All residents from our institute (N=27) voluntarily participated in the survey. The residents consisted of 4 (15%) women and 23 (85%) men, with 14 (56%) single residents and 12 (44%) married residents. No statistically significant difference existed in total debt >$100,000 between single and married residents or men and women. Forty-eight percent (n=13) of the residents had medical educational debt >$100,000, whereas 45% (n=12) had total debt >$200,000. Residents with total debt >$100,000 were concerned about their debt, whereas 1 of 4 residents with orthopedic residents financially and may cause stress and hinder their medical training. Appropriate measures should be taken to help residents properly manage their debt and to provide supplemental assistance with their financial struggles.

    Resident fatigue has become a point of emphasis in medical education and its effects on otolaryngology residents and their patients require further study. The purpose of our study was to evaluate the prevalence and nature of fatigue in otolaryngology residents, evaluate various quality of life measures, and investigate associations of increased fatigue with resident safety. Anonymous survey. Internet based. United States allopathic otolaryngology residents. None. The survey topics included demographics, residency structure, sleep habits and perceived stress. Responses were correlated with a concurrent Epworth Sleep Scale questionnaire to evaluate effects of fatigue on resident training and quality of life. 190 residents responded to the survey with 178 completing the Epworth Sleep Scale questionnaire. Results revealed a mean Epworth Sleep Scale score of 9.9±5.1 with a median of 10.0 indicating a significant number of otolaryngology residents are excessively sleepy. Statistically significant correlations between Epworth Sleep Scale and sex, region, hours of sleep, and work hours were found. Residents taking in-house call had significantly fewer hours of sleep compared to home call (p=0.01). Residents on "head and neck" (typically consisting of a large proportion of head and neck oncologic surgery) rotations tended to have higher Epworth Sleep Scale and had significantly fewer hours of sleep (p=.003) and greater work hours (potolaryngology residents are excessively sleepy. Our data suggest that the effects of fatigue play a role in resident well-being and resident safety. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background Congenital vascular rings may often cause unexplained respiratory symptoms in infants and young children. Their diagnosis and treatment are often delayed. Few studies of vascular rings have been reported in China.The aim of this study was to describe the clinical presentation, diagnosis and surgical management of infants and children with congenital vascular rings.Methods Clinical histories, physical examinations, investigations, image studies and surgical interventions were retrospectively evaluated in 7 children (age range: 2 months- 4 years, mean 7 months) with congenital vascular rings.Chest radiography was performed in all patients. Echocardiography and computed tomography (CT) with 3-dimensional (3D) reconstructions were performed in 6 patients. Esophagography, cardiac catheterization and angiography, and bronchoscopy were performed in 1, 1 and 4 children, respectively.Results Six of the 7 patients had respiratory symptoms, including recurrent cough, stridor and wheeze. Age at onset of symptoms ranged from 1 month to 11 months. Chest X-ray showed nothing important on the vascular rings, besides bronchitis and pneumonia. Contrast-enhanced CT diagnosed vascular rings in 6 patients. Four patients had double aortic arches, two had balanced arches and two were right arch dominant. One patient had a right aortic arch with left ligament and 1 patient had a pulmonary artery sling. Echocardiography failed to diagnose vascular rings in 2 patients. The esophagogram of 1 patient showed esophageal compression. Bronchoscopy of 4 patients showed compression of the distal trachea. Five of the 7 patients underwent surgical division of the vascular rings. Surgical observation confirmed the CT findings in each patient.Conclusions Patients, especially infants or young children, with recurrent respiratory symptoms such as chronic cough, stridor and wheeze, should be examined for the possible presence of congenital vascular rings.Contrast-enhanced CT can clearly show

  20. The impact of re-engineering a multi-institutional residency program on resident perceptions of the individual institutions. (United States)

    Dobkin, Eric; Fassler, Steven; Horowitz, Sheryl; Kirton, Orlando; Civetta, Joseph


    We report on the development of a survey tool used to assess resident perceptions of support and educational quality among multiple institutions in an integrated surgical residency, as well as its use in measuring the impact of re-engineering on that program. The University of Connecticut Integrated General Surgical Residency (UCIGSR) is a multisite program that was placed on probation by the Residency Review Committee in Surgery (RRC) in November 1998. This led to a re-evaluation and a re-engineering of the program. In order to better assess the residents' evaluation of the program, we serially examined their attitudes with a survey of 65 questions. A 4-point grading scale (1 = Poor, 4 = Excellent) was used, and each resident was required to complete a survey beginning shortly after RRC probation was announced and at 6-month intervals. Seven global questions in the survey, directed at residency program support and educational quality, were asked for each of the 4 individual adult hospitals, for a total of 28 questions. Statistical analysis of the data was performed using the Jonckhere-Terpstra and the Mann-Whitney U tests. The results demonstrated significant improvement for all 7 questions in all 4 hospitals between November 1998 (S1) and November 1999 (S3). Average scores for all 7 questions, Hospital Support (HS), Departmental Support (DS), Hospital Teaching (HT), Outpatient Teaching (OTC), Operating Room Teaching (ORT), Grand Rounds (GR), and Morbidity and Mortality Conferences (MM), improved in every hospital by 16-28%. In S1, 1 out of 28 questions received an average score greater than or equal to 3, whereas on the most recent survey, 17 of 28 scored greater than or equal to 3 and 78.5% of the questions demonstrated statistically significant improvement (p < 0.05). Three of the 4 hospitals now have a combined overall average score greater than or equal to 3 for all 7 questions. Areas of strength in each hospital had the least amount of improvement yet

    Availability of a proper vascular access is a basic condition for a proper extracorporeal replacement in end-stage chronic renal failure. However, biological factors, management and other problems, may variously condition their middle-long term survival. Therefore, personal experience of over 25 years has been critically reviewed in order to obtain useful information. In particular "hard" situations necessitating complex procedures have been examined but, if possible, preserving the peripherical vascular features.

  8. Global Health Simulation During Residency

    Directory of Open Access Journals (Sweden)

    Jane R. Rosenman MD


    Full Text Available Resident participation in international health electives (IHEs has been shown to be beneficial, yet not all residents have the opportunity to participate. We sought to determine whether participating in simulated global health cases, via the standardized Simulation Use for Global Away Rotations (SUGAR curriculum, was useful for all pediatric residents, not merely those planning to go on an IHE. Pediatric residents in our program took part in 2 SUGAR cases and provided feedback via an online survey. Thirty-six of 40 residents participated (90%; 72% responded to the survey. Three of 10 residents not previously planning to work in resource-limited settings indicated participation in SUGAR made them more likely to do so. Nearly all residents (88% felt SUGAR should be part of the residency curriculum. All felt better prepared for working cross-culturally. While designed to prepare trainees for work in resource-limited settings, SUGAR may be beneficial for all residents.

Methodology: As a comparator, a cross-sectional survey involving 76 Saudi residents from different training centers in Saudi Arabia namely; Riyadh, Jeddah, Medina, Abha, and Dammam and 15 Canadian. Results: The results showed that Canadian residents read more peer-reviewed, scholarly articles compared with Saudi residents (P=0.002. The primary surgical role for residents was to hold retractors during surgery. The survey respondents strongly supported the ability to recommend removal of incompetent trainers. Saudi trainees were more apprehensive of examinations than Canadian trainees (P<0.0001. Most residents preferred studying multiple-choice questions before examinations. Saudi and Canadian participants considered their programs to be overcrowded. Unlike Canadian participants, Saudi trainees reported an inadequate level of training (P<0.0001. Conclusion: Educational resources should be readily accessible and a mentorship system monitoring residents' progress should be developed. The role of the resident must be clearly defined and resident feedback should not be ignored. Given the importance of mastering basic orthopedic operative skills for residents, meaningful remedial action should be taken with incompetent trainers.

  10. Accelerating surgical training and reducing the burden of surgical disease in Haiti before and after the earthquake. (United States)

    DeGennaro, Vincent A; DeGennaro, Vincent A; Kochhar, Amit; Nathan, Nirmal; Low, Christopher; Avashia, Yash J; Thaller, Seth R


    In general, university-based global health initiatives have tended to focus on expanding access to primary care. In the past, surgical programs may have been characterized by sporadic participation with little educational focus. However, there have been some notable exceptions with plastic surgery volunteer missions. We offer another model of regularly scheduled surgical trips to rural Haiti in plastic and general surgery. The goal of these trips is to reduce the burden of surgical disease and ultimately repair every cleft lip/palate in Haiti. Another principal objective is to accelerate the training of American residents through increased case load and personal interaction with attending surgeons in a concentrated period. Diversity of the case load and the overall number of surgeries performed by residents in a typical surgical trip outpaces the experiences available during a typical week in an American hospital setting. More importantly, we continue to provide ongoing training to Haitian nurses and surgeons in surgical techniques and postoperative care. Our postoperative complication rate has been relatively low. Our follow-up rates have been lower than 70% despite intensive attempts to maintain continued communication with our patients. Through our experiences in surgical care in rural Haiti, we were able to quickly ramp up our trauma and orthopedic surgical care immediately after the earthquake. Project Medishare and the University of Miami continue to operate a trauma and acute care hospital in Port au Prince. The hospital provides ongoing orthopedic, trauma, and neurosurgical expertise from the rotating teams of American surgeons and training of Haitian surgeons in modern surgical techniques. We believe that surgical residencies in the United States can improve their training programs and reduce global surgical burden of disease through consistent trips and working closely with country partners.

  11. Leadership Training in Otolaryngology Residency. (United States)

    Bent, John P; Fried, Marvin P; Smith, Richard V; Hsueh, Wayne; Choi, Karen


    Although residency training offers numerous leadership opportunities, most residents are not exposed to scripted leadership instruction. To explore one program's attitudes about leadership training, a group of otolaryngology faculty (n = 14) and residents (n = 17) was polled about their attitudes. In terms of self-perception, more faculty (10 of 14, 71.4%) than residents (9 of 17, 52.9%; P = .461) considered themselves good leaders. The majority of faculty and residents (27 of 31) thought that adults could be taught leadership ability. Given attitudes about leadership ability and the potential for improvement through instruction, consideration should be given to including such training in otolaryngology residency.

  12. Modulation of systemic and intestinal immune response by interleukin-2 therapy in gastrointestinal surgical oncology. Personal experience in the context of current knowledge and future perspectives. (United States)

    Nespoli, Luca; Uggeri, Fabio; Romano, Fabrizio; Nespoli, Angelo; Brivo, Fernando; Fumagalli, Luca; Sargenti, Manuela; Uggeri, Franco; Gianotti, Luca


    Interactions between host and malignant tumor is currently under intensive investigation. The immune system seems to have a key role in cancer development and spread. Novel strategies to actively modulate the immune system have been proposed to improve the outcome of disease in patients with neoplasms. Our experience with systemic immunomodulation by interleukin-2 (IL-2) focused on both systemic and local immunity in surgical gastrointestinal cancer. Preoperative IL-2 subcutaneous injection was effective in counteracting postoperative immunosuppression, with a reduction of serum levels of IL-6 and the maintenance of preoperative levels of IL-12, a higher number of circulating total lymphocytes, and CD3(+) and CD4(+) T-cells, and a smaller decrease in circulating mature and immature dendritic cells (DCs), as well as a reduction in postoperative serum levels of vascular endothelial growth factor. At the intestinal level, in patients with colorectal cancer, preoperative administration of IL-2 affected both phenotype and function of resident dendritic cells and T-cells, skewing local immunity toward a more immunogenic one. Our data showed that immunomodulation by IL-2 was effective in counteracting the systemic postoperative immune suppression related to surgical stress. IL-2 was also active at a local level on intestinal immunity, affecting both phenotype and function of resident T-cells and DCs. Future studies will encompass the possibility of reaching more adequate intratumoral IL-2 concentrations by direct intralesional injection to maximize immunostimulatory effects and minimize adverse effects.

  13. Resident-to-resident violence triggers in nursing homes. (United States)

    Snellgrove, Susan; Beck, Cornelia; Green, Angela; McSweeney, Jean C


    Certified nurses' assistants (CNAs) employed by a rural nursing home in Northeast Arkansas described their perceptions of resident-to-resident violence in order to provide insight on factors, including unmet needs, that may trigger the phenomenon. Semistructured interviews were conducted with 11 CNAs. Data were analyzed using content analysis and constant comparison. Two categories of triggers emerged from the data-active and passive. Active triggers involved the actions of other residents that were intrusive in nature, such as wandering into a residents' personal space, taking a resident's belongings, and so forth. Passive triggers did not involve the actions of residents but related to the internal and external environment of the residents. Examples were factors such as boredom, competition for attention and communication difficulties. Results indicate that there are factors, including unmet needs within the nursing home environment that may be identified and altered to prevent violence between residents.

  14. Training future surgeons for management roles: the resident-surgeon-manager conference. (United States)

    Hanna, Waël C; Mulder, David S; Fried, Gerald M; Elhilali, Mostafa; Khwaja, Kosar A


    OBJECTIVE To demonstrate that senior surgical residents would benefit from focused training by professionals with management expertise. Although managerial skills are recognized as necessary for the successful establishment of a surgical practice, they are not often emphasized in traditional surgical residency curricula. DESIGN Senior residents from all surgical subspecialties at McGill University were invited to participate in a 1-day management seminar. Precourse questionnaires aimed at evaluating the residents' perceptions of their own managerial knowledge and preparedness were circulated. The seminar was then given in the form of interactive lectures and case-based discussions. The questionnaires were readministered at the end of the course, along with an evaluation form. Precourse and postcourse data were compared using the Freeman-Halton extension of the Fisher exact test to determine statistical significance (P < .05). SETTING McGill University Health Centre in Montreal, Quebec, Canada. PARTICIPANTS A total of 43 senior residents. RESULTS Before the course, the majority of residents (27 of 43 [63%]) thought that management instruction only happened "from time to time" in their respective programs. After the course, 15 residents (35%) felt that management topics were "well addressed," and 19 (44%) felt that management topics have been "very well addressed" (P < .01). Residents noted a significant improvement in their ability to perform the following skills after the course: giving feedback, delegating duties, coping with stress, effective learning, and effective teaching. On the ensemble of all managerial skills combined, 26 residents (60%) rated their performance as "good" or "excellent" after the course vs only 21 (49%) before the course (P = .02). Residents also noted a statistically significant improvement in their ability to perform the managerial duties necessary for the establishment of a surgical practice. CONCLUSIONS Surgical residency programs

  15. Thoughts of Quitting General Surgery Residency: Factors in Canada. (United States)

    Ginther, David Nathan; Dattani, Sheev; Miller, Sarah; Hayes, Paul


    Attrition rates in general surgery training are higher than other surgical disciplines. We sought to determine the prevalence with which Canadian general surgery residents consider leaving their training and the contributing factors. An anonymous survey was administered to all general surgery residents in Canada. Responses from residents who considered leaving their training were assessed for importance of contributing factors. The study was conducted at the Royal University Hospital, University of Saskatchewan, Saskatoon, Saskatchewan, Canada, a tertiary academic center. The response rate was approximately 34.0%. A minority (32.0%) reported very seriously or somewhat seriously considering leaving their training, whereas 35.2% casually considered doing so. Poor work-life balance in residency (38.9%) was the single-most important factor, whereas concern about future unemployment (16.7%) and poor future quality of life (15.7%) were next. Enjoyment of work (41.7%) was the most frequent mitigating factor. Harassment and intimidation were reported factors in 16.7%. On analysis, only intention to practice in a nonacademic setting approached significant association with thoughts of leaving (odds ratio = 1.92, CI = 0.99-3.74, p = 0.052). There was no association with sex, program, postgraduate year, relationship status, or subspecialty interest. There was a nonsignificant trend toward more thoughts of leaving with older age. Canadian general surgery residents appear less likely to seriously consider quitting than their American counterparts. Poor work-life balance in residency, fear of future unemployment, and anticipated poor future quality of life are significant contributors to thoughts of quitting. Efforts to educate prospective residents about the reality of the surgical lifestyle, and to assist residents in securing employment, may improve completion rates.

  16. The Fundamentals of Resident Dismissal. (United States)

    Schenarts, Paul J; Langenfeld, Sean


    Residents have the rights and responsibilities of both students and employees. Dismissal of a resident from a training program is traumatic and has lasting repercussions for the program director, the faculty, the dismissed resident, and the residency. A review of English language literature was performed using PUBMED and OVID databases, using the search terms, resident dismissal, resident termination, student dismissal, student and resident evaluation, legal aspects of education, and remediation. The references of each publication were also reviewed to identify additional appropriate citations. If the Just Cause threshold has been met, educators have the absolute discretion to evaluate academic and clinical performance. Legal opinion has stated that it is not necessary to wait until a patient is harmed to dismiss a resident. Evaluations should be standard and robust. Negative evaluations are not defamatory as the resident gave consent to be evaluated. Provided departmental and institutional polices have been followed, a resident can be dismissed without a formal hearing. Residencies are entitled to modify academic requirements and dismissal is not considered a breach of contract. Although there is anxiety regarding resident dismissal, the courts have uniformly supported faculty having this role. When indicated, failure to dismiss a resident also places the program director and the faculty at risk for educational malpractice.

  17. The basket trainer: A homemade laparoscopic trainer attainable to every resident

    Directory of Open Access Journals (Sweden)

    Jaber Nidal


    Full Text Available Laparoscopic trainers have been proved to be effective to improve skills of laparoscopic surgery; they are usually installed at hospital in the surgical department with limited access hours, usually inconvenient to the schedule of the resident. Simple trainer boxes are necessary for residents who desire developing their skills at home independently to the venue and hours of surgical departments. Our goal is to bring the laparoscopic trainer to the desktop of the surgical resident by making it very cheap, small, light, secure and easy to construct. We describe a model of laparoscopic trainer using steel basket which, we believe, meets all of the above-mentioned requirements. It is accessible to any personal budget and can be constructed with a minimum of hand skill. It is small and light enough to permit its daily use on the desktop of the resident for a couple of hours, then after it can be stocked in any locker.

  18. Antioxidants and vascular health. (United States)

    Bielli, Alessandra; Scioli, Maria Giovanna; Mazzaglia, Donatella; Doldo, Elena; Orlandi, Augusto


    Oxygen free radicals and other reactive oxygen species (ROS) are common products of normal aerobic cellular metabolism, but high levels of ROS lead to oxidative stress and cellular damage. Increased production of ROS favors vascular dysfunction, inducing altered vascular permeability and inflammation, accompanied by the loss of vascular modulatory function, the imbalance between vasorelaxation and vasoconstriction, and the aberrant expression of inflammatory adhesion molecules. Inflammatory stimuli promote oxidative stress generated from the increased activity of mitochondrial nicotinamide adenine dinucleotide phosphate oxidase, particularly of the Nox4 isoform, with the consequent impairment of mitochondrial β-oxidation. Vascular dysfunction due to the increase in Nox4 activity and ROS overproduction leads to the progression of cardiovascular diseases, diabetes, inflammatory bowel disease, and neurological disorders. Considerable research into the development of effective antioxidant therapies using natural derivatives or new synthetic molecules has been conducted. Antioxidants may prevent cellular damage by reducing ROS overproduction or interfering in reactions that involve ROS. Vitamin E and ascorbic acid are well known as natural antioxidants that counteract lipid peroxidative damage by scavenging oxygen-derived free radicals, thus restoring vascular function. Recently, preliminary studies on natural antioxidants such as goji berries, thymus, rosemary, green tea ginseng, and garlic have been conducted for their efficacy in preventing vascular damage. N-acetyl-cysteine and propionyl-L-carnitine are synthetic compounds that regulate ROS production by replacing endogenous antioxidants in both endothelial and smooth muscle cells. In this review, we consider the molecular mechanisms underlying the generation of oxidative stress-induced vascular dysfunction as well as the beneficial effects of antioxidant therapies.

  19. Surgical Lasers In Gynecology (United States)

    Schellhas, Helmut F.; Barnes, Alfonso E.


    Multipurpose surgical CO2 lasers marketed in the USA have been developed to be applicable to a variety of surgical procedures in many surgical fields. They are all suited for endoscopic surgical procedures and can be fitted to all standard surgical microscopes. They all can adjust the focal length of the laser beam to the different standard focal lengths of the surgical microscope which for instance in laryngoscopy is 400 mm and in colposcopy 300 mm. One laser instrument can even change the spot size in a given focal distance which is very advantageous for some microsurgical procedures (Merrimack Laboratories 820). All multipurpose surgical CO2 laser systems provide a multi-articulated surgical arm for free-hand surgery. The surgical arms are cumbersome to use but they are adapted to the surgeons needs with ingenuity. The practicality of the multi-articulated surgical arms depends mostly on the distance of the handpiece from the surgical console which now is also overbridged by the laser tube in most surgical laser system. The spot size of the beam is variable in most handpieces by interchangeable lenses which modify the focal distance of the beam and the power density. Another common feature in all systems is a coaxial He-Ne pilot light which provides a red spot which unfortunately becomes invisible in a bleeding surgical field. Most surgical laser systems have a spacial mode of TEM 00 which is essential for incisional surgery. The continuous mode of beam delivery is used for incisional surgery and also for most endoscopic procedures.

    Koga, Tomomichi; Kawamoto, Masashi


    To investigate whether gender difference has an effect on an anesthesia resident's ability to perform successful mask ventilation. Cohort study. Surgical operation theater of a university-affiliated hospital. 839 ASA physical status I, II, and III patients undergoing general anesthesia performed by residents. Mask ventilation was performed by 21 different anesthesia residents. Difficult mask ventilation was defined as the inability of an unassisted resident to maintain oxygen saturation, significant gas flow leakage beneath the face mask, need to increase gas flow, no perceptible chest movement, assistance required using a two-handed mask ventilation technique, or use of the oxygen flush valve more than twice. Instances of difficult mask ventilation were observed in 210 patients (25.0%), though all were adequately ventilated with a face mask. Difficult mask ventilation was observed significantly more often with female (29.8%) than male (20.0%) residents. Residents' gender was shown to be an independent risk factor for difficult mask ventilation. Gender difference has an effect on the mask ventilation learning process, as it was more difficult for female residents to provide a tight air seal in the early stage of training.

  2. Coexistence of pheochromocytoma with uncommon vascular lesions

    Directory of Open Access Journals (Sweden)

    Sunil Kumar Kota


    Full Text Available Background: Pheochromocytoma/paragangliomas have been described to be associated with rare vascular abnormalities like renal artery stenosis. Coexistence of physiologically significant renal artery lesions is a compounding factor that alters management and prognosis of pheochromocytoma patients. Apart from individual case reports, data on such association in Indian population is not available. The aim of this study is to find the nature and prevalence of associated vascular abnormalities. Materials and Methods: From 1990 to 2010, a total of 50 patients were diagnosed with pheochromocytoma/paragangliomas. Hospital charts of these patients were reviewed retrospectively to identify those with unusual vascular abnormalities. Available literature was also reviewed. Results: Of the 50 patients with pheochromocytoma, 7 (14% had coexisting vascular lesions including renal artery stenosis in 4, aortoarteritis in 1, aortic aneurysm in 1 and inferior vena cava thrombosis in 1. Pheochromocytoma was adrenal in 42 and extra adrenal in 8. Laparoscopic adrenalectomy was done in the patients. One patient with renal artery stenosis due to intimal fibrosis was subjected to percutaneous balloon angioplasty; the other three improved after adrenalectomy and lysis of fibrous adhesive bands. The patient with aortoarteritos was treated with oral steroids. Inferior vena cava thrombosis was reversed with anticoagulants. The patient with abdominal aortic aneurysm was advised for annual follow-up on account of its size of 4.5 cm and asymptomatic presentation. Conclusion: There are multiple mechanisms that can lead to renal artery stenosis and other vascular abnormalities in a case of pheochromocytoma. A high index of suspicion is necessary to enable both entities to be diagnosed preoperatively and allow proper planning of surgical therapy. Incomplete diagnosis may lead to persistent hypertension postoperatively in a case of associated renal artery stenosis.

Medical records were reviewed for demographic information, preoperative nucleus grade, femtosecond laser pretreatment, operative procedure times, total operating room times, and surgical complications. Review of digital video records provided quantitative interval measurements of core steps of the procedures, including completion of incisions, anterior capsulotomy, nucleus removal, cortical removal, and intraocular lens implantation.Results: Total room time, operation time, and corneal incision completion time were found to be significantly longer in the femtosecond laser group versus the traditional phacoemulsification group (each P<0.05. Mean duration for manual completion of anterior capsulotomy was shorter in the laser group (P<0.001. There were no statistically significant differences in the individual steps of nucleus removal, cortical removal, or intraocular lens placement. Surgical complication rates were not significantly different between the groups.Conclusion: In early cases, resident completion of femtosecond cataract surgery is generally less efficient when trainees have more experience with traditional phacoemulsification. FLACS was found to have a significant advantage in completion of capsulotomy, but subsequent surgical steps were not shorter or longer. Resident learning curve for the

    Our goal in this study was to examine Accreditation Council for Graduate Medical Education case logs for Stanford anesthesia residents graduating in 2013 (25 residents) and 2014 (26 residents). The resident with the fewest recorded patients in 2013 had 43% the number of patients compared with the resident with the most patients, and in 2014, this equaled 48%. There were residents who had 75% more than the class average number of cases for several of the 12 case types and 3 procedure types required by the Accreditation Council for Graduate Medical Education. Also, there were residents with fewer than half as many for some of the required cases or procedure types. Some of the variability may have been because of the hazards of self-reporting.

    Little is known about the factors that influence medical student selection of obstetrics and gynecology (ob-gyn) residency programs. We assessed the factors influencing residency program selection by fourth-year medical students pursuing ob-gyn training. A voluntary, anonymous, 19-question survey of residency selection factors was distributed to all fourth-year medical students interviewing at 1 of 5 academic ob-gyn departments for a residency position during the 2013-2014 interview season. Participants were surveyed about the relative importance (not important, somewhat important, important) of various residency selection factors, including operative experience, exposure to subspecialties, curricular experience, access to fellowships, and administrative aspects of residency, including adherence to duty hour restrictions. Of 322 potential respondents, 262 (81%) completed the survey. Surgical training and training in laparoscopic surgery were deemed "important" by nearly all respondents (98%, 258 of 262, and 97%, 253 of 262, respectively). Factors that were considered "not important" by a significant group of respondents included maternity/paternity leave policies (22%, 58 of 259); opportunity for international rotations/electives (20%, 51 of 259); exposure to quality and safety initiatives (13%, 34 of 259); and training in abortion (13%, 34 of 262). Fourth-year medical students identified surgical training as the most important factor in selecting an ob-gyn residency, a finding that is particularly relevant as decreasing and changing surgical volumes affect residency training in this specialty.

  6. Ageing and vascular ageing (United States)

    Jani, B; Rajkumar, C


    There is an age related decline in various physiological processes. Vascular ageing is associated with changes in the mechanical and the structural properties of the vascular wall, which leads to the loss of arterial elasticity and reduced arterial compliance. Arterial compliance can be measured by different parameters like pulse wave velocity, augmentation index, and systemic arterial compliance. There is evidence that arterial compliance is reduced in disease states such as hypertension, diabetes, and end stage renal failure. Changes in arterial compliance can be present before the clinical manifestation of cardiovascular disease. Pharmacological and non‐pharmacological measures have been shown to improve arterial compliance. Arterial compliance may constitute an early cardiovascular risk marker and may be useful in assessing the effects of drugs on the cardiovascular system. Pharmacogenetics and genetics of arterial compliance in the future will improve our knowledge and understanding about vascular ageing. PMID:16754702

    OBJECTIVE To investigate whether training otorhinolaryngology residents to criterion performance levels (proficiency) on the Endoscopic Sinus Surgery Simulator produces individuals whose performance in the operating room is at least equal to those who are trained by performing a fixed number of surgical procedures. DESIGN Prospective cohort. SETTING Two academic medical centers in New York City. PARTICIPANTS Otorhinolaryngology junior residents composed of 8 experimental subjects and 6 control subjects and 6 attending surgeons. INTERVENTION Experimental subjects achieved benchmark proficiency criteria on the Endoscopic Sinus Surgery Simulator; control subjects repeated the surgical procedure twice. MAIN OUTCOME MEASURES Residents completed validated objective tests to assess baseline abilities. All subjects were videotaped performing an initial standardized surgical procedure. Residents were videotaped performing a final surgery. Videotapes were assessed for metrics by an expert panel. RESULTS Attendings outperformed the residents in most parameters on the initial procedure. Experimental and attending groups outperformed controls in some parameters on the final procedure. There was no difference between resident groups in initial performance, but the experimental subjects outperformed the control subjects in navigation in the final procedure. Most important, there was no difference in final performance between subgroups of the experimental group on the basis of the number of trials needed to attain proficiency. CONCLUSIONS Simulator training can improve resident technical skills so that each individual attains a proficiency level, despite the existence of an intrinsic range of abilities. This proficiency level translates to at least equal, if not superior, operative performance compared with that of current conventional training with finite repetition of live surgical procedures.

    Hussain, Muhammad I; Zahid, Muhammad; Khan, Abdul-Waheed; Askri, Hasan; Khan, AbulFazal A


    To determine the outcome of various techniques of vascular repair in terms of repair related complications and limb salavagibility. From January 1999 to December 2005, this retrospective study was conducted in the Department of General Surgery, Lahore General Hospital, Lahore, Pakistan. The patients, who underwent various surgical interventions for extremity vascular trauma, were included in this study. Those, who underwent primary amputation due to non-salvageable injuries or who presented with late complications of vascular injuries were excluded. Ninety-three patients underwent different surgical procedures for extremity vascular trauma. Majority of the patients were young, (mean, 29.4 years) male (91.3%). Penetrating trauma was the most common mode of injury (77.4%). The median time interval between injury and repair was 4.5 hours. Superficial femoral artery was the most frequently injured artery (26.8%). Graft repair was carried out in 41 patients (46.6%), while (34.1%) of the patients had end-to-end anastomosis. Wound infection was the most common complication (18.2%). Seven patients (7.5%) had secondary amputations and 3 (3.2%) died from other injuries. Vascular reconstruction was successful in 89.3% of the patients. Early revascularization by employing simple repair or interposition autogenous vein graft repair results in successful limb salvage with acceptable complication rate.

  9. Lower Extremity Permanent Dialysis Vascular Access. (United States)

    Parekh, Vishal B; Niyyar, Vandana D; Vachharajani, Tushar J


    Hemodialysis remains the most commonly used RRT option around the world. Technological advances, superior access to care, and better quality of care have led to overall improvement in survival of patients on long-term hemodialysis. Maintaining a functioning upper extremity vascular access for a prolonged duration continues to remain a challenge for dialysis providers. Frequently encountered difficulties in clinical practice include (1) a high incidence of central venous catheter-related central vein stenosis and (2) limited options for creating a functioning upper extremity permanent arteriovenous access. Lack of surgical skills, fear of complications, and limited involvement of the treating nephrologists in the decision-making process are some of the reasons why lower extremity permanent dialysis access remains an infrequently used option. Similar to upper extremity vascular access options, lower extremity arteriovenous fistula remains a preferred access over arteriovenous synthetic graft. The use of femoral tunneled catheter as a long-term access should be avoided as far as possible, especially with the availability of newer graft-catheter hybrid devices. Our review provides a summary of clinical evidence published in surgical, radiology, and nephrology literature highlighting the pros and cons of different types of lower extremity permanent dialysis access.

  10. [Resident foreigners in Spain]. (United States)

    Solana, A M; Pascual De Sans, A


    The authors review trends in the size of the resident foreign population in Spain over time since the 1940s. A continuing growth over time, with temporal fluctuations, is noted, with a rapid rise in immigration in the 1980s, leading to new legislation designed to control immigration in 1985-1986 and 1991. The authors note that Europeans, particularly from countries of the European Union, make up a large percentage of the foreign population, but that the number of immigrants from developing countries has increased significantly in the last 10 years.

  11. Students to Surgeons: Increasing Matriculation in Surgical Specialties. (United States)

    Grover, Karan; Agarwal, Prateek; Agarwal, Nitin; Tabakin, Marcia D; Swan, Kenneth G


    Introduction Our nation suffers from a shortage in surgeons. This deficiency must be addressed at the medical student level. Increasing faculty and resident interaction with junior students augments surgical interest. Our surgical interest group has recently redefined its role to address these concerns. Methods A multifocal approach has been implemented to increase interest in the surgical specialties. Each academic year, senior students recruit first and second year students to our group to establish early exposure. Members receive didactic presentations from surgical faculty, addressing various topics, on a biweekly basis. In addition, scrubbing, knot-tying, and suturing workshops address technical skills throughout the semester. Membership and match data were collated and analyzed. Results Over the past 5 years, the enrollment in the student interest group increased significantly from 112 to 150. Accordingly, we have observed a parallel increase in the number of students who have successfully matched into surgical residencies. A record number of students (37) from the class of 2013 matched into surgical specialties, representing an 85% increase over the last decade. After creating bylaws and electing societal officers, the group has been recognized by the school's Student Council and given financial support. At present, the group is fiscally solvent with support from the institution, surgery department, and faculty. Conclusion As the demand for surgeons increases so too does the need to increase student interest in surgery. Our school has been successful because of our surgical interest group, and we encourage other schools to adopt a similar approach. © The Author(s) 2016.

  12. Manual of Surgical Instruments

    Directory of Open Access Journals (Sweden)

    Olga Lidia Sánchez Sarría


    Full Text Available Surgical instruments are the group of tools used in surgical procedures. They are very expensive and sophisticated. Consequently, a standardized and meticulous care is essential; they should go through the decontamination, cleaning and sterilization process. These instruments are designed in order to provide surgeons with tools that help them to perform a basic surgical procedure; there are multiple variations and the design depends on their function. This paper aims at showing all surgical instruments that can be used in an operating room during surgery and are not generally included in the medical literature.

    Lobato, Ramiro D; Jiménez Roldan, Luis; Alen, José F; Castaño, Ana M; Munarriz, Pablo M; Cepeda, Santiago; Lagares, Alfonso


    A programme proposal for competency-based Neurosurgery training adapted to the specialization project is presented. This proposal has been developed by a group of neurosurgeons commissioned by the SENEC (Spanish Society of Neurosurgery) and could be modified to generate a final version that could come into force coinciding with the implementation of the specialization programme. This document aims to facilitate the test of the new programme included in the online version of our journal. Total training period is 6 years; initial 2 years belong to the surgery specialization and remaining 4 years belong to core specialty period. It is a competency-based programmed based on the map used by the US Accreditation Council for Graduate Medical Education (ACGME) including the following domains of clinical competency: Medical knowledge, patient care, communication skills, professionalism, practice-based learning and improvement, health systems, interprofessional collaboration and professional and personal development. Subcompetencies map in the domains of Knowledge and Patient care (including surgical competencies) was adapted to the one proposed by AANS and CNS (annex 1 of the programme). A subcompetency map was also used for the specialization rotations. Resident's training is based on personal study (self-learning) supported by efficient use of information sources and supervised clinical practice, including bioethical instruction, clinical management, research and learning techniques. Resident evaluation proposal includes, among other instruments, theoretical knowledge tests, objective and structured evaluation of the level of clinical competency with real or standardised patients, global competency scales, 360-degree evaluation, clinical record audits, milestones for residents progress and self-assessment (annex 2). Besides, residents periodically assess the teaching commitment of the department's neurosurgeons and other professors participating in rotations, and annually

  18. Preoperative optimization of the vascular surgery patient

    Directory of Open Access Journals (Sweden)

    Zhan HT


    Full Text Available Henry T Zhan,1 Seth T Purcell,1,2 Ruth L Bush1 1Texas A&M Health Science Center College of Medicine, Bryan, 2Baylor Scott and White, Temple, TX, USA Abstract: It is well known that patients who suffer from peripheral (noncardiac vascular disease often have coexisting atherosclerotic diseases of the heart. This may leave the patients susceptible to major adverse cardiac events, including death, myocardial infarction, unstable angina, and pulmonary edema, during the perioperative time period, in addition to the many other complications they may sustain as they undergo vascular surgery procedures, regardless of whether the procedure is performed as an open or endovascular modality. As these patients are at particularly high risk, up to 16% in published studies, for postoperative cardiac complications, many proposals and algorithms for perioperative optimization have been suggested and studied in the literature. Moreover, in patients with recent coronary stents, the risk of noncardiac surgery on adverse cardiac events is incremental in the first 6 months following stent implantation. Just as postoperative management of patients is vital to the outcome of a patient, preoperative assessment and optimization may reduce, and possibly completely alleviate, the risks of major postoperative complications, as well as assist in the decision-making process regarding the appropriate surgical and anesthetic management. This review article addresses several tools and therapies that treating physicians may employ to medically optimize a patient before they undergo noncardiac vascular surgery.

  20. Hypercholesterolaemia and vascular dementia. (United States)

    Appleton, Jason P; Scutt, Polly; Sprigg, Nikola; Bath, Philip M


    Vascular dementia (VaD) is the second commonest cause of dementia. Stroke is the leading cause of disability in adults in developed countries, the second major cause of dementia and the third commonest cause of death. Traditional vascular risk factors-diabetes, hypercholesterolaemia, hypertension and smoking-are implicated as risk factors for VaD. The associations between cholesterol and small vessel disease (SVD), stroke, cognitive impairment and subsequent dementia are complex and as yet not fully understood. Similarly, the effects of lipids and lipid-lowering therapy on preventing or treating dementia remain unclear; the few trials that have assessed lipid-lowering therapy for preventing (two trials) or treating (four trials) dementia found no evidence to support the use of lipid-lowering therapy for these indications. It is appropriate to treat those patients with vascular risk factors that meet criteria for lipid-lowering therapy for the primary and secondary prevention of cardiovascular and cerebrovascular events, and in line with current guidelines. Managing the individual patient in a holistic manner according to his or her own vascular risk profile is recommended. Although the paucity of randomized controlled evidence makes for challenging clinical decision making, it provides multiple opportunities for on-going and future research, as discussed here. © 2017 The Author(s).

  1. Instituting a Surgical Skills Competition Increases Technical Performance of Surgical Clerkship Students Over Time. (United States)

    Leraas, Harold J; Cox, Morgan L; Bendersky, Victoria A; Sprinkle, Shanna S; Gilmore, Brian F; Gunasingha, Rathnayaka M; Tracy, Elisabeth T; Sudan, Ranjan


    Surgical skills training varies greatly between institutions and is often left to students to approach independently. Although many studies have examined single interventions of skills training, no data currently exists about the implementation of surgical skills assessment as a component of the medical student surgical curriculum. We created a technical skills competition and evaluated its effect on student surgical skill development. Second-year medical students enrolled in the surgery clerkship voluntarily participated in a surgical skills competition consisting of knot tying, laparoscopic peg transfer, and laparoscopic pattern cut. Winning students were awarded dinner with the chair of surgery and a resident of their choice. Individual event times and combined times were recorded and compared for students who completed without disqualification. Disqualification included compromising cutting pattern, dropping a peg out of the field of vision, and incorrect knot tying technique. Timed performance was compared for 2 subsequent academic years using Mann-Whitney U test. Overall, 175 students competed and 71 students met qualification criteria. When compared by academic year, 2015 to 2016 students (n = 34) performed better than 2014 to 2015 students (n = 37) in pattern cut (133s vs 167s, p = 0.040), peg transfer (66s vs 101s, p skills competition improves student technical performance. Further research is needed regarding long-term benefits of surgical competitions for medical students. Copyright © 2017 Association of Program Directors in Surgery. Published by Elsevier Inc.

  2. Renal posttransplant's vascular complications

    Directory of Open Access Journals (Sweden)

    Bašić Dragoslav


    Full Text Available INTRODUCTION Despite high graft and recipient survival figures worldwide today, a variety of technical complications can threaten the transplant in the postoperative period. Vascular complications are commonly related to technical problems in establishing vascular continuity or to damage that occurs during donor nephrectomy or preservation [13]. AIM The aim of the presenting study is to evaluate counts and rates of vascular complications after renal transplantation and to compare the outcome by donor type. MATERIAL AND METHODS A total of 463 kidneys (319 from living related donor LD and 144 from cadaveric donor - CD were transplanted during the period between June 1975 and December 1998 at the Urology & Nephrology Institute of Clinical Centre of Serbia in Belgrade. Average recipients' age was 33.7 years (15-54 in LD group and 39.8 (19-62 in CD group. Retrospectively, we analyzed medical records of all recipients. Statistical analysis is estimated using Hi-squared test and Fischer's test of exact probability. RESULTS Major vascular complications including vascular anastomosis thrombosis, internal iliac artery stenosis, internal iliac artery rupture obliterant vasculitis and external iliac vein rupture were analyzed. In 25 recipients (5.4% some of major vascular complications were detected. Among these cases, 22 of them were from CD group vs. three from LD group. Relative rate of these complications was higher in CD group vs. LD group (p<0.0001. Among these complications dominant one was vascular anastomosis thrombosis which occurred in 18 recipients (17 from CD vs. one from LD. Of these recipients 16 from CD lost the graft, while the rest of two (one from each group had lethal outcome. DISCUSSION Thrombosis of renal allograft vascular anastomosis site is the most severe complication following renal transplantation. In the literature, renal allograft thrombosis is reported with different incidence rates, from 0.5-4% [14, 15, 16]. Data from the

  3. Surgical ethics and the challenge of surgical innovation. (United States)

    Angelos, Peter


    Surgical ethics as a specific discipline is relatively new to many. Surgical ethics focuses on the ethical issues that are particularly important to the care of surgical patients. Informed consent for surgical procedures, the level of responsibility that surgeons feel for their patients' outcomes, and the management of surgical innovation are specific issues that are important in surgical ethics and are different from other areas of medicine. The future of surgical progress is dependent on surgical innovation, yet the nature of surgical innovation raises specific concerns that challenge the professionalism of surgeons. These concerns will be considered in the following pages.

  4. Training needs for general dentistry residents to place and restore two-implant-retained mandibular overdentures. (United States)

    Malmstrom, Hans; Xiao, Jin; Romanos, Georgios E; Ren, Yan-Fang


    Implant therapy is rapidly becoming a standard of care for replacing missing dentition. Predoctoral dental curricula include some training in the implant restorative phase but offer limited exposure to the surgical phase, so it is important for postdoctoral general dentistry residency programs to provide competency training in all phases of implant therapy. The aim of this study was to determine the training needed for general dentistry residents to achieve competence in this area, specifically by defining the number of clinical experiences necessary in both the surgical and prosthetic phases of implant-retained mandibular overdenture construction (IRMOD). Fifteen Advanced Education in General Dentistry (AEGD) residents at one academic dental institution placed two implants in a total of 50 patients with edentulous mandibles and subsequently restored them with IRMOD. The supervising faculty member and the residents evaluated the competency level on a five-point scale after each implant placement and prosthetic case completion. According to the faculty evaluations, the residents achieved surgical competence after placing two implants in four to six cases and prosthetic management competence after restoring two to four cases of IRMOD. All 50 patients were satisfied with the treatment outcomes of IRMOD. This study concluded that general dentistry residents could potentially achieve competence in both the surgical and prosthetic phases of implant therapy while enrolled in an AEGD program.

  5. International plastic surgery missions: a framework for resident education using the CanMEDS competencies. (United States)

    White, Colin P; Lecours, Catherine; Bortoluzzi, Patricia; Caouette-Laberge, Louise; Ying, Yvonne


    Residency education has shifted over the past decade in an attempt to graduate well-rounded physicians. There is a recognition that a physician's abilities must extend beyond medical knowledge. The Royal College of Physicians and Surgeons of Canada introduced the CanMEDS physician competency framework in 2005. The framework provides 7 areas of competencies that are aimed at providing improved patient care. These competencies are medical expert, communicator, collaborator, manager, health advocate, scholar, and professional. Teaching and evaluating many of these competencies is often challenging for residency training programs. We believe that international surgical missions provide a prime opportunity to teach and evaluate all CanMEDS' roles.Plastic surgery is a field with many different organizations involved in international surgery. Many plastic surgery training programs offer opportunities for residents to become involved in these international surgical missions. Through these trips, residents gain surgical experience, see a variety and volume of clinical cases, and have the opportunity to travel to a foreign country and experience different cultures. We believe that international plastic surgery surgical missions also provide an exceptional micro environment for the teaching of CanMEDS roles. Using examples from residents' personal experiences on international plastic surgery missions to China, Mali, and Cambodia, we describe the benefits of these missions in transferring the CanMEDS competencies to resident training.

    To qualify and characterize resident overnight activity. A prospective 3-phase study was conducted of surgical residents with attention to activities performed on the overnight rotation: needs assessment, direct observation of activities, and feedback. This study was conducted at the University of Oklahoma Health Sciences Center, Oklahoma City, Oklahoma. This is both a tertiary referral center and the only American College of Surgeons (ACS) verified level 1 trauma center in the state. This study included current surgical residents within the residency program. During the study period, 270 pages were individually recorded, with 60% of these pages defined as time-sensitive activities. In addition, most of the pages involved pressing patient-care issues irrespective of postgraduate year level. Analyses revealed that residents spend most of their time performing educational activities (62%). On feedback, residents reported overall satisfaction with the learning opportunities during night-shift (6.4/7.0) and indicated their perceptions of an adequate balance of service and education on night float (6.6/7.0). This correlates with our annual rotation assessment where residents identify night-float as an overall positive experience which provides educational benefit. Work-hour restrictions induce residency programs to adapt to new training models. Our results report a breakdown of resident activities while on night-float and demonstrate that overnight shifts continue to provide important educational opportunities during training.

    Postgraduate year one (PGY1) and postgraduate year two (PGY2) residencies serve to develop pharmacists into skillful clinicians who provide advanced patient-centered care in various general and specialized areas of pharmacy practice. Pharmacy residencies are a minimum requirement for many clinical pharmacy positions, as well as for positions in academia. The role of clinical pharmacists typically includes teaching, regardless of whether they pursue an academic appointment. Common teaching duties of pharmacist-clinicians include giving continuing education or other invited presentations, providing education to colleagues regarding clinical initiatives, precepting pharmacy students (early and advanced experiences) and residents, and educating other health care professionals. Although ASHP provides accreditation standards for PGY1 and PGY2 residencies, the standards pertaining to teaching or education training are vague. Through the years, teaching certificate programs that develop residents' teaching skills and better prepare residents for a diverse pharmacy job market have increased in popularity; moreover, teaching certificate programs serve as an attractive recruitment tool. However, the consistency of requirements for teaching certificate programs is lacking, and standardization is needed. The Task Force on Residencies developed two sets of guidelines to define teaching experiences within residencies. The first guideline defines the minimum standards for teaching experiences in any residency-training program. The second guideline is for programs offering a teaching certificate program to provide standardization, ensuring similar outcomes and quality on program completion. One of the main differences between the guidelines is the recommendation that residency programs offering a teaching certificate program be affiliated with an academic institution to provide the pedagogy and variety of teaching experiences for the resident. Residency program directors should

  10. Global health training among U.S. residency specialties: a systematic literature review (United States)

    Hau, Duncan K.; Smart, Luke R.; DiPace, Jennifer I.; Peck, Robert N.


    ABSTRACT Background: Interest in global health training during residency is increasing. Global health knowledge is also becoming essential for health-care delivery today. Many U.S. residency programs have been incorporating global health training opportunities for their residents. We performed a systematic literature review to evaluate global health training opportunities and challenges among U.S. residency specialties. Methods: We searched PubMed from its earliest dates until October 2015. Articles included were survey results of U.S. program directors on global health training opportunities, and web-based searches of U.S. residency program websites on global health training opportunities. Data extracted included percentage of residency programs offering global health training within a specialty and challenges encountered. Results: Studies were found for twelve U.S. residency specialties. Of the survey based studies, the specialties with the highest percentage of their residency programs offering global health training were preventive medicine (83%), emergency medicine (74%), and surgery (71%); and the lowest were orthopaedic surgery (26%), obstetrics and gynecology (28%), and plastic surgery (41%). Of the web-based studies, the specialties with the highest percentage of their residency programs offering global health training were emergency medicine (41%), pediatrics (33%), and family medicine (22%); and the lowest were psychiatry (9%), obstetrics and gynecology (17%), and surgery (18%). The most common challenges were lack of funding, lack of international partnerships, lack of supervision, and scheduling. Conclusion: Among U.S. residency specialties, there are wide disparities for global health training. In general, there are few opportunities in psychiatry and surgical residency specialties, and greater opportunities among medical residency specialties. Further emphasis should be made to scale-up opportunities for psychiatry and surgical residency specialties

  11. Design, development and implementation of a surgical simulation pathway curriculum for biliary disease. (United States)

    Buchholz, Joseph; Vollmer, Charles M; Miyasaka, Kiyoyuki W; Lamarra, Denise; Aggarwal, Rajesh


    The initial focus of simulation in surgical education was to provide instruction in procedural tasks and technical skills. Recently, the importance of instruction in nontechnical areas, such as communication and teamwork, was realized. On rotation, the surgical resident requires proficiency in both technical and non-technical skills through the entire patient care pathway, i.e., pre-, intra- and postoperatively. The focus was upon implementation of a biliary disease-based surgical simulation curriculum. The cornerstones of this module were clinical care pathway simulation sessions, at the commencement and conclusion of the 3 days. Each resident completed a simulated outpatient encounter with a standardized patient (SP) presenting with biliary colic, performed a laparoscopic cholecystectomy on a porcine model in a simulated operating room and completed an uncomplicated follow-up visit with the same SP. Assessments of resident performance were collected for every pathway scenario using standardized assessment forms approved by the American Board of Surgery. Additional formative sessions included hands-on, didactic and SP encounter sessions. The biliary surgical simulation pathway curriculum was successful implemented over the course of a 3-day, immersive module. The curriculum was delivered within the Penn Medicine Clinical Simulation Center and accommodated six junior surgical resident learners. The curriculum was divided into 4-h sessions, each led by a department faculty member. The cost of the implementation approximated $17,500 (USD). It is imperative that surgical residents undergo simulation training directly linked to their hospital responsibilities so as to provide immediate performance improvement and reduce errors in the clinical environment. This pathway curriculum has successfully shown the feasibility to implement this novel approach to surgical simulation for junior resident training at an academic medical center. Such a patient-focused approach to

  12. Emergency Medicine Resident Orientation: How Training Programs Get Their Residents Started (United States)

    McGrath, Jillian; Barrie, Michael; Way, David P.


    Introduction The first formal orientation program for incoming emergency medicine (EM) residents was started in 1976. The last attempt to describe the nature of orientation programs was by Brillman in 1995. Now almost all residencies offer orientation to incoming residents, but little is known about the curricular content or structure of these programs. The purpose of this project was to describe the current composition and purpose of EM resident orientation programs in the United States. Methods In autumn of 2014, we surveyed all U.S. EM residency program directors (n=167). We adapted our survey instrument from one used by Brillman (1995). The survey was designed to assess the orientation program’s purpose, structure, content, and teaching methods. Results The survey return rate was 63% (105 of 167). Most respondents (77%) directed three-year residencies, and all but one program offered intern orientation. Orientations lasted an average of nine clinical (Std. Dev.=7.3) and 13 non-clinical days (Std. Dev.=9.3). The prototypical breakdown of program activities was 27% lectures, 23% clinical work, 16% skills training, 10% administrative activities, 9% socialization and 15% other activities. Most orientations included activities to promote socialization among interns (98%) and with other members of the department (91%). Many programs (87%) included special certification courses (ACLS, ATLS, PALS, NRP). Course content included the following: use of electronic medical records (90%), physician wellness (75%), and chief complaint-based lectures (72%). Procedural skill sessions covered ultrasound (94%), airway management (91%), vascular access (90%), wound management (77%), splinting (67%), and trauma skills (62%). Conclusion Compared to Brillman (1995), we found that more programs (99%) are offering formal orientation and allocating more time to them. Lectures remain the most common educational activity. We found increases in the use of skills labs and specialty

    Kahilogullari, G; Comert, A; Ozdemir, M; Brohi, R A; Ozgural, O; Esmer, A F; Egemen, N; Karahan, S T


    The aim of this study was to provide detailed information about the arterial vascularization of the splenium of the corpus callosum (CC). The splenium is unique in that it is part of the largest commissural tract in the brain and a region in which pathologies are seen frequently. An exact description of the arterial vascularization of this part of the CC remains under debate. Thirty adult human brains (60 hemispheres) were obtained from routine autopsies. Cerebral arteries were separately cannulated and injected with colored latex. Then, the brains were fixed in formaldehyde, and dissections were performed using a surgical microscope. The diameter of the arterial branches supplying the splenium of the CC at their origin was investigated, and the vascularization patterns of these branches were observed. Vascular supply to the splenium was provided by the anterior pericallosal artery (40%) from the anterior circulation and by the posterior pericallosal artery (88%) and posterior accessory pericallosal artery (50%) from the posterior circulation. The vascularization pattern of the splenium differs in each hemisphere and is usually supplied by multiple branches. The arterial vascularization of the splenium of the CC was studied comprehensively considering the ongoing debate and the inadequacy of the studies on this issue currently available in the literature. This anatomical knowledge is essential during the treatment of pathologies in this region and especially for splenial arteriovenous malformations.

  15. Peroneal tendons well vascularized: results from a cadaveric study. (United States)

    van Dijk, Pim A D; Madirolas, F Xavier; Carrera, Ana; Kerkhoffs, Gino M M J; Reina, Francisco


    Peroneal tendon tears are relatively common injuries that seem to have a poor healing tendency. The discussion goes that peroneal tendons have avascular zones, contributing to the poor healing of those tears. The purpose of this study was to provide evidence on the vascularization pattern of the peroneal tendons. Ten adult fresh-frozen cadavers were obtained from a university-affiliated body donation programme. The femoral artery was injected with natural coloured latex at the level of the knee. Macroscopic and microscopic dissections were performed to visualize the vascularization towards the peroneal tendons. To expose intratendinous vascularity, the tendons were cleared using a modified Spälteholz technique. In all specimens, blood was mainly supplied by the peroneal artery through a posterolateral vincula connecting both tendons. Branches were bifurcated every 3.9 ± 1.8 cm, starting 24 ± 5.3 cm proximal to the tip of the fibula. Eight out of 10 (80%) specimens had poor vascularized zones in the peroneus longus tendon. No avascular zones were found in the peroneus brevis tendon. The peroneal tendons are well vascularized by the peroneal artery, via vessels running through a common vincula for both tendons. In the peroneus brevis, no avascular zones were found. To keep the tendons well vascularized and therefore improve tendon healing, surgeons should be careful leaving the vincula intact during surgical procedures.

    Arikan, Fuat; Vilalta, Jordi; Torne, Ramon; Chocron, Ivette; Rodriguez-Tesouro, Ana; Sahuquillo, Juan


    Ischemic lesions related to surgical procedures are a major cause of postoperative morbidity in patients with cerebral vascular disease. There are different systems of neuromonitoring to detect intraoperative ischemic events, including intraoperative monitoring of oxygen tissue pressure (PtiO2). The aim of this article was to describe, through the discussion of 4 cases, the usefulness of intraoperative PtiO2 monitoring during vascular neurosurgery. In presenting these cases, we demonstrate that monitoring PtiO2 is a reliable way to detect early ischemic events during surgical procedures. Continuous monitoring of PtiO2 in an area at risk allows the surgeon to resolve the cause of the ischemic event before it evolves to an established cerebral infarction.

  18. Incorporating resident research into the dermatology residency program

    Directory of Open Access Journals (Sweden)

    Wagner RF Jr


    Full Text Available Richard F Wagner Jr, Sharon S Raimer, Brent C Kelly Department of Dermatology, The University of Texas Medical Branch, Galveston, Texas, USA Abstract: Programmatic changes for the dermatology residency program at The University of Texas Medical Branch were first introduced in 2005, with the faculty goal incorporating formal dermatology research projects into the 3-year postgraduate training period. This curriculum initially developed as a recommendation for voluntary scholarly project activity by residents, but it evolved into a program requirement for all residents in 2009. Departmental support for this activity includes assignment of a faculty mentor with similar interest about the research topic, financial support from the department for needed supplies, materials, and statistical consultation with the Office of Biostatistics for study design and data analysis, a 2-week elective that provides protected time from clinical activities for the purpose of preparing research for publication and submission to a peer-reviewed medical journal, and a departmental award in recognition for the best resident scholarly project each year. Since the inception of this program, five classes have graduated a total of 16 residents. Ten residents submitted their research studies for peer review and published their scholarly projects in seven dermatology journals through the current academic year. These articles included three prospective investigations, three surveys, one article related to dermatology education, one retrospective chart review, one case series, and one article about dermatopathology. An additional article from a 2012 graduate about dermatology education has also been submitted to a journal. This new program for residents was adapted from our historically successful Dermatology Honors Research Program for medical students at The University of Texas Medical Branch. Our experience with this academic initiative to promote dermatology research by

  19. Resident surgeon efficiency in femtosecond laser-assisted cataract surgery (United States)

    Pittner, Andrew C; Sullivan, Brian R


    Purpose Comparison of resident surgeon performance efficiencies in femtosecond laser-assisted cataract surgery (FLACS) versus conventional phacoemulsification. Patients and methods A retrospective cohort study was conducted on consecutive patients undergoing phacoemulsification cataract surgery performed by senior ophthalmology residents under the supervision of 1 attending physician during a 9-month period in a large Veterans Affairs medical center. Medical records were reviewed for demographic information, preoperative nucleus grade, femtosecond laser pretreatment, operative procedure times, total operating room times, and surgical complications. Review of digital video records provided quantitative interval measurements of core steps of the procedures, including completion of incisions, anterior capsulotomy, nucleus removal, cortical removal, and intraocular lens implantation. Results Total room time, operation time, and corneal incision completion time were found to be significantly longer in the femtosecond laser group versus the traditional phacoemulsification group (each Pcataract surgery is generally less efficient when trainees have more experience with traditional phacoemulsification. FLACS was found to have a significant advantage in completion of capsulotomy, but subsequent surgical steps were not shorter or longer. Resident learning curve for the FLACS technology may partially explain the disparities of performance. Educators should be cognizant of a potential for lower procedural efficiency when introducing FLACS into resident training. PMID:28203055

  20. Education Research: Neurology resident education (United States)

    Mayans, David; Schneider, Logan; Adams, Nellie; Khawaja, Ayaz M.; Engstrom, John


    Objective: To survey US-trained graduating neurology residents who are American Academy of Neurology members, in an effort to trend perceived quality and completeness of graduate neurology education. Methods: An electronic survey was sent to all American Academy of Neurology members graduating from US neurology residency programs in the Spring of 2014. Results: Of 805 eligible respondents, 24% completed the survey. Ninety-three percent of adult neurology residents and 56% of child neurology residents reported plans to pursue fellowship training after residency. Respondents reported a desire for additional training in neurocritical care, neuro-oncology, neuromuscular diseases, botulinum toxin injection, and nerve blocks. There remains a clear deficit in business training of neurology residents, although there was notable improvement in knowledge of coding and office management compared to previous surveys. Discussion: Although there are still areas of perceived weakness in neurology training, graduating neurology residents feel generally well prepared for their chosen careers. However, most still pursue fellowship training for reasons that are little understood. In addition to certain subspecialties and procedures, practice management remains deficient in neurology training and is a point of future insecurity for most residents. Future curriculum changes should consider resident-reported gaps in knowledge, with careful consideration of improving business training. PMID:26976522

    Hyung Ook Kim; Sang Il Hwang; Hungdai Kim; Jun Ho Shin


    BACKGROUND:Appropriate palliation for unresectable pancreatic head cancer is most important. This study was undertaken to compare the survival of patients with biliary obstruction caused by unresectable pancreatic head cancer after surgical and non-surgical palliation. METHODS:We retrospectively reviewed 69 patients who underwent palliative treatment for unresectable pancreatic head cancer. Fifty-two patients with locally advanced disease (local vascular invasion) and 17 with distant metastatic disease were included. The patients were divided into two groups, surgical and non-surgical palliation. RESULTS:Thirty-eight patients underwent biliary bypass surgery and 31 had percutaneous transhepatic biliary drainage (PTBD). There was no signiifcant difference in the early complications, successful biliary drainage, recurrent jaundice, and 30-day mortality between surgical palliation and PTBD. However, in 52 patients whose tumor was unresectable secondary to local vascular invasion, the rate of recurrent jaundice after successful surgical biliary palliation was lower than that in patients who had non-surgical palliation (P CONCLUSIONS:In patients with preoperative evaluations showing potentially resectable tumors and/or no metastatic lesions, surgical exploration should be performed. Thus, in patients who have unresectable cancer or limited metastatic disease on exploration, surgical palliation should be performed for longer survival and better quality of survival.

    Ivanov, A N; Puchinyan, D M; Norkin, I A


    Endothelium is an important regulator of selective permeability of the vascular wall for different molecules and cells. This review summarizes current data on endothelial barrier function. Endothelial glycocalyx structure, its function and role in the molecular transport and leukocytes migration across the endothelial barrier are discussed. The mechanisms of transcellular transport of macromolecules and cell migration through endothelial cells are reviewed. Special section of this article addresses the structure and function of tight and adherens endothelial junction, as well as their importance for the regulation of paracellular transport across the endothelial barrier. Particular attention is paid to the signaling mechanism of endothelial barrier function regulation and the factors that influence on the vascular permeability.

    This grant supported the Second International Conference on Plant Vascular Biology (PVB 2010) held July 24-28, 2010 on the campus of Ohio State University, Columbus, Ohio. Biao Ding (Ohio State University; OSU) and David Hannapel (Iowa State University; ISU) served as co-chairs of this conference. Biao Ding served as the local organizer. PVB is defined broadly here to include studies on the biogenesis, structure and function of transport systems in plants, under conditions of normal plant growth and development as well as of plant interactions with pathogens. The transport systems cover broadly the xylem, phloem, plasmodesmata and vascular cell membranes. The PVB concept has emerged in recent years to emphasize the integrative nature of the transport systems and approaches to investigate them.

  4. Neurobiology of Vascular Dementia

    Directory of Open Access Journals (Sweden)

    Ana-Maria Enciu


    Full Text Available Vascular dementia is, in its current conceptual form, a distinct type of dementia with a spectrum of specific clinical and pathophysiological features. However, in a very large majority of cases, these alterations occur in an already aged brain, characterized by a milieu of cellular and molecular events common for different neurodegenerative diseases. The cell signaling defects and molecular dyshomeostasis might lead to neuronal malfunction prior to the death of neurons and the alteration of neuronal networks. In the present paper, we explore some of the molecular mechanisms underlying brain malfunction triggered by cerebrovascular disease and risk factors. We suggest that, in the age of genetic investigation and molecular diagnosis, the concept of vascular dementia needs a new approach.

  5. Adhesion in vascular biology



    The vasculature delivers vital support for all other tissues by supplying oxygen and nutrients for growth and by transporting the immune cells that protect and cure them. Therefore, the microvasculature developed a special barrier that is permissive for gasses like oxygen and carbon dioxide, while fluids are kept inside and pathogens are kept out. While maintaining this tight barrier, the vascular wall also allows immune cells to exit at sites of inflammation or damage, a process that is call...

  6. Transumbilical laparoscopic appendectomy performed by residents is safe and feasible. (United States)

    Endo, Kazuhiro; Kujirai, Dai; Maeda, Hinako; Ishida, Takashi; Terauchi, Toshiaki; Kimata, Masaru; Shinozaki, Hiroharu; Lefor, Alan Kawarai; Sata, Naohiro


    The aim of this study was to compare the clinical outcomes of single-incision transumbilical laparoscopy-assisted appendectomy performed by surgical residents and attending surgeons. We reviewed the clinical outcomes of 131 transumbilical laparoscopy-assisted appendectomies performed from January 2011 to June 2014. During the study period, 13 residents and 6 board-certified attending surgeons performed the procedures. For all operations performed by residents and attending surgeons, we reviewed and compared gender, age, BMI, body temperature, white blood cell count, C-reactive protein serum level, and the presence of a fecalith or abscess. Clinical outcomes including operative time, estimated blood loss, need for additional ports, conversion to open surgery, intraoperative complications, postoperative complications, and postoperative hospital stay were compared between the two groups. The mean preoperative white blood cell count in the resident-operated group was significantly higher than in the attending-operated group (14.0 vs 10.8 ×10(3) /mm(3) , P = 0.007). There were no other significant differences in clinical variables between the two groups. Outcomes show that estimated blood loss was significantly higher (23.4 vs 9.8 mL, P = 0.031) and operative time tended to be longer (86.0 vs 72.0 min, P = 0.056) in the resident-operated group. No other significant differences were observed. Transumbilical laparoscopy-assisted appendectomy performed by residents is feasible and safe. It is an acceptable as a part of routine surgical training. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

  7. Surgical ethics: surgical virtue and more. (United States)

    Vercler, Christian J


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

  8. Modern management of adult coarctation: transcatheter and surgical options. (United States)

    Schneider, Heiko; Uebing, Anselm; Shore, Darryl F


    Coarctation of the aorta (CoA), a juxtaductal obstructive lesion in the descending aorta and commonly associated with hypoplasia of the aortic arch occurs in 5-8% of patients with congenital heart disease. Since the initial surgical corrections in the 1950, surgical and transcatheter options have constantly evolved. Nowadays, transcatheter options are widely accepted as the initial treatment of choice in adults presenting with native or recurrent CoA. Surgical techniques are mainly reserved for patients with complex aortic arch anatomy such as extended arch hypoplasia or stenosis or para-CoA aneurysm formation. Extended aneurysms can be covered by conformable stents but stent implantation may require preparative vascular surgery. Complex re-CoA my best be treated by an ascending to descending bypass conduit. The following review aims to describe current endovascular and surgical practice pointing out modern developments and their limitations.

    Miles, R R; Seward, K P; Benett, W J; Tendick, F; Bentley, L; Stephan, P L


    A project was undertaken to improve robotic surgical tools for telerobotic minimally invasive surgery. The major objectives were to reduce the size of the tools to permit new surgical procedures in confined spaces such as the heart and to improve control of surgical tools by locating positional sensors and actuators at the end effector rather than external to the patient as is currently the state of the technology. A new compact end-effector with wrist-like flexibility was designed. Positional sensors based on MEMS microfabrication techniques were designed.

  10. Resident training in pathology: From resident's point of view

    Directory of Open Access Journals (Sweden)



    Full Text Available In many recent studies in the literature have described and commented on “competency based resident training” in pathology. According to this model, competencies are subclassified in 6 main categories: Patient care, medical knowledge, practice based learning and improvement, interpersonal and communication skills, professionalism, and systems based practice. Assessment of competency forms the main component of this model.Under the framework of Ankara Society of Pathology, a working group, composed of 11 residents, 6 of which representing the Training and Research Hospitals of Ministry of Health and the rest representing the university hospitals in Ankara, was established in order to participate in the think-tank about resident training in pathology. A questionnaire, composed of 12 questions, was prepared. According to this questionnaire, the number of trainers in the university hospitals is much higher than in the commercial hospitals. While the total number of cases and cases per resident do not differ between the university and commercial hospitals, microscopes used for the educational purposes are significantly less in the commercial hospitals, that is due to less number of binocular microscopes. The amount of resident training program, which consists of intra and intersectional meetings, are similar in the university and commercial hospitals, however, theoretic lectures are given only in 3 departments. Residents working in the university hospitals have obviously heavier burden than in the commercial hospitals. Lastly, residents generally exclaimed that the time dedicated to the macroscopy training is less sufficient than time used for the microscopy training.The factors affecting the training of resident in pathology are divided into two main groups: 1 Factors directly affecting training (quality of trainer, time dedicated for education, feed back, eg. and 2 Conditions which waste residents' time. For instant, workload which does need

  11. The vascular anatomy of the lumbrical muscles in the hand. (United States)

    Bilge, Okan; Pinar, Yelda; Ozer, Mehmet Asim; Govsa, Figen


    The lumbrical muscles are located in the midpalm, dorsal to the palmar aponeurosis. The main function of these muscles is an indirect contribution to interphalangeal joint extension by decreasing the flexor effect of the flexor digitorum profundus muscle. Due to their minor biomechanical functions and suitable constructions, these muscles have been preferred in reconstructive surgery as local transposition flaps or pedicled flaps. Despite the surgical and clinical importance, vascular anatomical studies of these muscles are not well represented in the current literature. This study was performed in the Department of Anatomy of the Faculty of Medicine of the Ege University. Thirty-four cadaver hands, injected with red-coloured latex were used, and we aimed to describe the morphometry and vascular anatomy of the lumbrical muscles. We measured the length and width of the muscles, after removing their epimisium, and the diameter and length of the arteries to the muscles. The outcomes of our study determined that the length and width of the lumbrical muscles were reduced significantly from radial towards ulnar sides. The lumbrical muscles were supplied from both their palmar and dorsal surfaces by both superficial and deep palmar arches and/or their branches. We also described the level of entry of the dominant arteries for each lumbrical muscle and measured the size of the vessels and muscles to guide some surgical approaches. This anatomical study could guide for some surgical approaches and reduce the deficiency about the vascular anatomical patterns of the lumbrical muscles in the literature.

  12. MIS training in Canada: a national survey of general surgery residents. (United States)

    Qureshi, Alia; Vergis, Ashley; Jimenez, Carolina; Green, Jessica; Pryor, Aurora; Schlachta, Christopher M; Okrainec, Allan


    General surgery trainees' perceptions regarding their own laparoscopic training remain poorly defined. The objective of this survey was to identify and evaluate learner experiences with laparoscopic procedures in general surgery programs on a national level. Two hundred eighty-four residents were identified and contacted at English-speaking general surgery programs across Canada. Each was asked to complete a web- or paper-based survey regarding their demographics, experiences with basic and advanced minimally invasive surgery (MIS) procedures, and perceived barriers to training. Two hundred fifty-two of 284 (89%) surveyed residents responded. Eighty-seven percent of the residents had access to a skills lab that taught MIS techniques; however, standardized MIS curricula were implemented 53% of the time. Eighty percent of residents felt that skills lab training translated to improved performance in the OR. Although 90% of residents felt that they would be comfortable performing basic laparoscopic procedures, only 8% stated they would be comfortable performing advanced procedures at the end of their training. Moreover, 90% of general surgery residents felt that it was the academic surgical department's responsibility to teach both basic and advanced procedures, and 35% of respondents felt their surgical program was meeting this requirement. Half of the residents felt they had limited opportunity to be a primary surgeon because an MIS fellow was present. There exists a wide disparity between the expectations of residents and their actual experience. The majority of residents are concerned that they will not acquire sufficient laparoscopic skills during their training to perform advanced cases in practice. Additionally, the balance between resident and fellow-level cases needs to be more clearly defined as the majority of respondents identified the presence of a MIS fellow as a negative learning influence. Finally, although most centers had a surgical skills lab, 47% of

  13. Distance to hospital and utilization of surgical services in Haiti: do children, delivering mothers, and patients with emergent surgical conditions experience greater geographical barriers to surgical care? (United States)

    Friedman, James M; Hagander, Lars; Hughes, Christopher D; Nash, Katherine A; Linden, Allison F; Blossom, Jeff; Meara, John G


    An inverse relationship between healthcare utilization and distance to care has been previously described. The purpose of this study was to evaluate this effect related to emergency and essential surgical care in central Haiti. We conducted a retrospective review of operative logbooks from the Clinique Bon Sauveur in Cange, Haiti, from 2008 to 2010. We used Geographic Information Systems to map the home locations of all patients. Spearman's correlation was used to determine the relationship between surgical utilization and distance, and a multivariate linear regression model identified characteristics associated with differences in distances traveled to care. The highest annual surgical utilization rate was 184 operations/100,000 inhabitants. We found a significant inverse correlation between surgical utilization rate and distance from residence to hospital (rs = -0.68, p = 0.02). The median distance from residence to hospital was 55.9 km. Pediatric patients lived 10.1% closer to the hospital than adults (p Haiti. Children and patients receiving obstetric, gynecologic or emergent surgery lived significantly closer to the hospital, and these groups may need special attention to ensure adequate access to surgical care.

  14. Outcomes of arterial vascular extremity trauma in pediatric patients. (United States)

    Kirkilas, Mary; Notrica, David M; Langlais, Crystal S; Muenzer, Jared T; Zoldos, Jozef; Graziano, Kathleen


    Vascular trauma in children, although rare, carries significant risk for repair. Here we report outcomes from a single trauma center for children with extremity vascular trauma, proximal to the digits. Retrospective chart review of patients less than age 18years with an acute, non-iatrogenic traumatic arterial vascular injury of the upper and/or lower extremity between January 2008 and December 2013. Abstracted patient demographics, injury characteristics, surgical management, and disposition were summarized and compared with nonparametric methods. 23 children comprised the study cohort: median age of 8years (IQR: 4.6-12), 61% (n=14) males, 100% survival. Penetrating injuries were the predominate mechanism (n=17, 74%). The median time to presentation was 154min (IQR: 65-330). Acute operations for revascularization included a primary repair (n=15, 65%) or reversed vein graft (n=7, 30%). Fasciotomies were done for 3 (13%) patients. Three amputations were done for failed revascularization. Upper extremity vascular injury (n=15, 65%) was more common. The rate of associated extremity fracture was similar between upper (21%) and lower (33%) extremities (p=0.643). Eight (35%) patients required additional surgery most commonly for debridement, washouts and dressing changes. Three patients' hospital stays were complicated by infection. Impaired function was the most common short- and long-term complication (60%, 75%). Pediatric vascular injuries are commonly associated with penetrating injuries and male gender and occurred more frequently in the upper extremities. Overall patency rates after repair were 87%. Fasciotomies were done in 13% of patients, and the overall surgical amputation rate was 13%. There was no mortality in this cohort; however, multiple operations are commonly required, including the return to OR for washouts, debridements and dressing changes. The most common short- and long-term complication was impaired function. Overall good results are achievable in

  6. Reducing oral and maxillofacial surgery resident risk exposure: lessons from graduate medical education reform. (United States)

    Buhrow, Suzanne Morse; Buhrow, Jack A


    It is estimated that, in the United States, more than 40,000 patients are injured each day because of preventable medical errors. Although numerous studies examine the causes of medical trainee errors and efforts to mitigate patient injuries in this population, little research exists on adverse events experienced by oral and maxillofacial surgery (OMFS) residents or strategies to improve patient safety awareness in OMFS residency programs. The authors conducted a retrospective literature review of contemporary studies on medical trainees' reported risk exposure and the impact of integrating evidence-based patient safety training into residency curricula. A review of the literature suggests that OMFS residents face similar risks as medical trainees in medical, surgical, and anesthesia residency programs and may benefit from integrating competency-based safety training in the OMFS residency curriculum. OMFS trainees face particular challenges when transitioning from dental student to surgical resident, particularly related to their limited clinical exposure to high-reliability organizations, which may place them at higher risk than other medical trainees. OMFS educators should establish resident competence in patient safety principles and system improvement strategies throughout the training period.

  7. Incidence of Postoperative Deep Venous Thrombosis Is Higher among Cardiac and Vascular Surgery Patients as Compared with General Surgery Patients. (United States)

    Aziz, Faisal; Patel, Mayank; Ortenzi, Gail; Reed, Amy B


    Unlike general surgery patients, most of vascular and cardiac surgery patients receive therapeutic anticoagulation during operations. The purpose of this study was to report the incidence of deep venous thrombosis (DVT) among cardiac and vascular surgery patients, compared with general surgery. The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent surgical procedures from 2005 to 2010. Patients who developed DVT within 30 days of an operation were identified. The incidence of DVT was compared among vascular, general, and cardiac surgery patients. Risk factors for developing postoperative DVT were identified and compared among these patients. Of total 2,669,772 patients underwent surgical operations in the period between 2005 and 2010. Of all the patients, 18,670 patients (0.69%) developed DVT. The incidence of DVT among different surgical specialties was cardiac surgery (2%), vascular surgery (0.99%), and general surgery (0.66%). The odds ratio for developing DVT was 1.5 for vascular surgery patients and 3 for cardiac surgery patients, when compared with general surgery patients (P cardiac surgery was 2, when compared with vascular surgery (P cardiac surgery patients as compared with that of general surgery patients. Intraoperative anticoagulation does not prevent the occurrence of DVT in the postoperative period. These patients should receive DVT prophylaxis in the perioperative period, similar to other surgical patients according to evidence-based guidelines. Copyright © 2015 Elsevier Inc.

  10. Value Added: the Case for Point-of-View Camera use in Orthopedic Surgical Education. (United States)

    Karam, Matthew D; Thomas, Geb W; Taylor, Leah; Liu, Xiaoxing; Anthony, Chris A; Anderson, Donald D


    Orthopedic surgical education is evolving as educators search for new ways to enhance surgical skills training. Orthopedic educators should seek new methods and technologies to augment and add value to real-time orthopedic surgical experience. This paper describes a protocol whereby we have started to capture and evaluate specific orthopedic milestone procedures with a GoPro® point-of-view video camera and a dedicated video reviewing website as a way of supplementing the current paradigm in surgical skills training. We report our experience regarding the details and feasibility of this protocol. Upon identification of a patient undergoing surgical fixation of a hip or ankle fracture, an orthopedic resident places a GoPro® point-of-view camera on his or her forehead. All fluoroscopic images acquired during the case are saved and later incorporated into a video on the reviewing website. Surgical videos are uploaded to a secure server and are accessible for later review and assessment via a custom-built website. An electronic survey of resident participants was performed utilizing Qualtrics software. Results are reported using descriptive statistics. A total of 51 surgical videos involving 23 different residents have been captured to date. This includes 20 intertrochanteric hip fracture cases and 31 ankle fracture cases. The average duration of each surgical video was 1 hour and 16 minutes (range 40 minutes to 2 hours and 19 minutes). Of 24 orthopedic resident surgeons surveyed, 88% thought capturing a video portfolio of orthopedic milestones would benefit their education. There is a growing demand in orthopedic surgical education to extract more value from each surgical experience. While further work in development and refinement of such assessments is necessary, we feel that intraoperative video, particularly when captured and presented in a non-threatening, user friendly manner, can add significant value to the present and future paradigm of orthopedic surgical

  11. The minimally invasive approach is associated with reduced surgical site infections in obese patients undergoing proctectomy. (United States)

    Pasam, R T; Esemuede, I O; Lee-Kong, S A; Kiran, R P


    While laparoscopic colorectal resection may be underused in technically challenging circumstances, the minimally invasive approach may in fact maximally benefit patients at the greatest risk of complications. Obesity and proctectomy pose particular technical challenges during laparoscopic resection and are also associated with the greatest risks of complications, especially surgical site infections (SSIs). We evaluated the role of laparoscopy in minimizing SSI in such patients. From the American College of Surgeons-National Surgical Quality Improvement Program database, outcomes for obese [body mass index (BMI) ≥ 30 kg/m(2)] and non-obese (BMI laparoscopy on SSI for obese patients undergoing proctectomy. OC patients were more likely than OP, LC, and LP, respectively, to undergo emergency operation and have an American Society of Anesthesiologists (ASA) score of 3-5. Overall SSI rates after OC, OP, LC, and LP were 15.2, 17.6, 8.6, and 10.1 %, respectively (p obese patients, the rates were 18.7, 22.3, 10.7, and 13.3 % (p obesity, proctectomy, younger age, race, steroid use, diabetes, chronic obstructive pulmonary disease, prior wound infection, transfusion history, previous operation within 30 days, coronary artery or vascular disease, ASA class 3-5, tobacco use, resident involvement, male gender, albumin Laparoscopy reduced the risk of SSI by at least 35 % across all BMI classes and procedures, an effect that persisted on multivariate analysis even in obese patients undergoing proctectomy. In colorectal surgery, an already high-risk outlier for SSI, obesity and proctectomy are associated with the highest risk of SSI. Despite the particular technical challenges of laparoscopy in these circumstances, the minimally invasive approach attenuates the risk of SSI in these high-risk patients and thus should be strongly considered during treatment planning.

  12. Early resident-to-resident physics education in diagnostic radiology. (United States)

    Kansagra, Akash P


    The revised ABR board certification process has updated the method by which diagnostic radiology residents are evaluated for competency in clinical radiologic physics. In this work, the author reports the successful design and implementation of a resident-taught physics course consisting of 5 weekly, hour-long lectures intended for incoming first-year radiology residents in their first month of training. To the author's knowledge, this is the first description of a course designed to provide a very early framework for ongoing physics education throughout residency without increasing the didactic burden on faculty members. Twenty-six first-year residents spanning 2 academic years took the course and reported subjective improvement in their knowledge (90%) and interest (75%) in imaging physics and a high level of satisfaction with the use of senior residents as physics educators. Based on the success of this course and the minimal resources required for implementation, this work may serve as a blueprint for other radiology residency programs seeking to develop revised physics curricula.

  13. Impact of Resident Surgeons on Procedure Length based on Common Pediatric Otolaryngology Cases (United States)

    Puram, Sidharth V.; Kozin, Elliott D.; Sethi, Rosh; Alkire, Blake; Lee, Daniel J.; Gray, Stacey T.; Shrime, Mark G.; Cohen, Michael


    Background Surgical education remains an important mission of academic medical centers. Financial pressures, however, may favor improved operating room (OR) efficiency at the expense of surgical education. We aim to characterize resident impact on the duration of procedural time using common pediatric otolaryngologic cases which do not necessitate a surgical assistant and assess whether other factors modify the extent to which residents impact OR efficiency. Study Design We retrospectively reviewed resident and attending surgeon total OR and procedural times for isolated tonsillectomy, adenoidectomy, tonsillectomy with adenoidectomy (T&A) and bilateral myringotomy with tube insertion between 2009 and 2013. We included cases supervised or performed by one of four teaching surgeons in children with ASA otolaryngology procedures. While residents may increase operative times, addressing other system-wide issues may decrease impact of time needed for education and added efficiencies of resident participation may exist throughout the perioperative period. Our model is applicable to surgical education across specialties. Level of Evidence 4 PMID:25251257

  14. Quality Improvement-Focused Departmental Grand Rounds Reports: A Strategy to Engage General Surgery Residents. (United States)

    Abelson, Jonathan S; Mitchell, Katrina B; Afaneh, Cheguevera; Rich, Barrie S; Frey, Theresa J; Gellman, Carol; Pomp, Alfons; Michelassi, Fabrizio


    Background Many institutions are seeking ways to enhance their surgical trainees' quality improvement (QI) skills. Objective To educate trainees about the importance of lifelong performance improvement, chief residents at New York Presbyterian Hospital-Weill Cornell Medicine are members of a multidisciplinary QI team tasked with improving surgical outcomes. We describe the process and the results of this effort. Methods Our analysis used 2 data sources to assess complication rates: the National Surgical Quality Improvement Program (NSQIP) and ECOMP, our own internal complication database. Chief residents met with a multidisciplinary QI team to review complication rates from both data sources. Chief residents performed a case-by-case analysis of complications and a literature search in areas requiring improvement. Based on this information, chief residents met with the multidisciplinary team to select interventions for implementation, and delivered QI-focused grand rounds summarizing the QI process and new interventions. Results Since 2009, chief residents have presented 16 QI-focused grand rounds. Urinary tract infections (UTIs) and surgical site infections (SSIs) were the most frequently discussed. Interventions to improve UTIs and SSIs were introduced to the department of surgery through these reports in 2011 and 2012. During this time we saw improvement in outcomes as measured by NSQIP odds ratio. Conclusions Departmental grand rounds are a suitable forum to review NSQIP data and our internal, resident-collected data as a means to engage chief residents in QI improvement, and can serve as a model for other institutions to engage surgery residents in QI projects.

  15. What effects have resident work-hour changes had on education, quality of life, and safety? A systematic review. (United States)

    Harris, Joshua D; Staheli, Greg; LeClere, Lance; Andersone, Diana; McCormick, Frank


    More than 15 years ago, the Institute of Medicine (IOM) identified medical error as a problem worthy of greater attention; in the wake of the IOM report, numerous changes were made to regulations to limit residents' duty hours. However, the effect of resident work-hour changes remains controversial within the field of orthopaedics. We performed a systematic review to determine whether work-hour restrictions have measurably influenced quality-of-life measures, operative and technical skill development, resident surgical education, patient care outcomes (including mortality, morbidity, adverse events, sentinel events, complications), and surgeon and resident attitudes (such as perceived effect on learning and training experiences, personal benefit, direct clinical experience, clinical preparedness). We performed a systematic review of PubMed, Scopus, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Google Scholar using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Inclusion criteria were any English language peer-reviewed articles that analyzed the effect(s) of orthopaedic surgery resident work-hour restrictions on patient safety, resident education, resident/surgeon quality of life, resident technical operative skill development, and resident surgeon attitudes toward work-hour restrictions. Eleven studies met study inclusion criteria. One study was a prospective analysis, whereas 10 studies were of level IV evidence (review of surgical case logs) or survey results. Within our identified studies, there was some support for improved resident quality of life, improved resident sleep and less fatigue, a perceived negative impact on surgical operative and technical skill, and conflicting evidence on the topic of resident education, patient outcomes, and variable attitudes toward the work-hour changes. There is a paucity of high-level or clear evidence evaluating the effect of the changes to resident work

  17. Surgical fidelity: comparing the microscope and the endoscope. (United States)

    Cote, Martin; Kalra, Ricky; Wilson, Taylor; Orlandi, Richard R; Couldwell, William T


    Both the microscope and the endoscope are widely used as visualization tools in neurosurgery; however, surgical dexterity when operating with each may differ. The aim of this study was to compare the surgical fidelity when using each of these visualization tools. Junior residents and expert surgeons performed standardized motor tasks under microscopic and endoscopic visualization. Demerits for inaccuracy and time needed to complete the tasks were used to compare the surgeons' performance with the microscope and the endoscope. The participants also performed a motor task under direct vision using different instruments to evaluate whether the shape of the instrument had any impact on the surgical fidelity. For the junior residents, the number of demerits accrued was lower with the microscope than with the endoscope, and the time needed to complete the tasks was also lower with the microscope. There was no difference in the number of demerits between the microscopic and the endoscopic experts, but the microscopic expert completed the task in a shorter time. There was no difference in demerits or performance time when comparing a short, straight instrument and a longer, bayoneted one. For junior residents, surgical fidelity is higher with the microscope than with the endoscope. This difference vanishes with experience, but a slower speed of execution is observed with endoscopic visualization, both in junior and expert surgeons.

  18. Bypass materials in vascular surgery (United States)

    Eidt, Daniela; Roll, Stephanie; Kulp, Werner; Müller-Nordhorn, Jaqueline; Vauth, Christoph; Greiner, Wolfgang; Willich, Stefan N.; von der Schulenburg, Johann-Matthias


    Introduction Arteriosclerotic changes can lead to circulatory disturbances in various areas of the human vascular system. In addition to pharmacological therapy and the management of risk factors (e. g. hypertension, diabetes, lipid metabolism disorders, and lifestyle), surgical interventions also play an important role in the treatment of arteriosclerosis. Long-segment arterial occlusions, in particular, can be treated successfully with bypass sur-gery. A number of different materials are available for this type of operation, such as autologous vein or pros-thetic grafts comprised of polytetrafluoroethylene (PTFE) or Dacron®. Prosthetic materials are used especially in the treatment of peripheral artery disease, such as in aortoiliac or femoropopliteal bypass surgery. The present report will thus focus on this area in order to examine the effectiveness of different bypass materials. Among the efforts being made to refine the newly introduced DRG system in Germany, analysing the different bypass materials used in vascular surgery is particularly important. Indeed, in its current version the German DRG system does not distinguish between bypass materials in terms of reimbursement rates. Differences in cost structures are thus of especial interest to hospitals in their budget calculations, whereas both private and statutory health insurance funds are primarily interested in long-term results and their costs. Objectives The goal of this HTA is to compare the different bypass materials used in vascular surgery in terms of their medical efficiency and cost-effectiveness, as well as with regard to their ethical, social and legal implications. In addition, this report aims to point out the areas in which further medical, epidemiological and health economic research is still needed.

  20. The relationship between grit and resident well-being. (United States)

    Salles, Arghavan; Cohen, Geoffrey L; Mueller, Claudia M


    The well-being of residents in general surgery is an important factor in their success within training programs. Consequently, it is important to identify individuals at risk for burnout and low levels of well-being as early as possible. The aim of this study was to test the hypothesis that resident well-being may be related to grit, a psychological factor defined as perseverance and passion for long-term goals. One hundred forty-one residents across 9 surgical specialties at 1 academic medical center were surveyed; the response rate was 84%. Perseverance was measured using the Short Grit Scale. Resident well-being was measured with (1) burnout using the Maslach Burnout Inventory and (2) psychological well-being using the Dupuy Psychological General Well-Being Scale. Grit was predictive of later psychological well-being both as measured by the Maslach Burnout Inventory (B = -.20, P = .05) and as measured by the Psychological General Well-Being Scale (B = .27, P < .01). Measuring grit may identify those who are at greatest risk for poor psychological well-being in the future. These residents may benefit from counseling to provide support and improve coping skills.

  1. Does operative experience during residency correlate with reported competency of recent general surgery graduates? (United States)

    Safavi, Arash; Lai, Sarah; Butterworth, Sonia; Hameed, Morad; Schiller, Dan; Skarsgard, Erik


    Background Identification of attributes of residency training that predict competency would improve surgical education. We hypothesized that case experience during residency would correlate with self-reported competency of recent graduates. Methods Aggregate case log data of residents enrolled in 2 general surgery programs were collected over a 12-month period and stratified into Surgical Council on Resident Education (SCORE) categories. We surveyed recent (surgery (4, 0.04%), and the least common EU procedure was abdomen–spleen (1, 0.1%). The questionnaire response rate was 45%. For EC procedures, self-reported competency was highest in skin and soft tissue, thoracic and head and neck (each 100%) and lowest in vascular–venous (54%), whereas for EU procedures it was highest in abdomen–general (100%) and lowest in vascular–arterial (62%). The correlation between case volume and self-reported competency was poor (R = 0.2 for EC procedures). Conclusion Self-reported competency correlates poorly with operative case experience during residency. Other curriculum factors, including specific rotations and timing, balance between inpatient and outpatient surgical experience and competition for cases, may contribute to procedural competency acquisition during residency.

  2. An In Vitro Murine Model of Vascular Smooth Muscle Cell Mineralization. (United States)

    Kelynack, Kristen J; Holt, Stephen G


    Vascular calcification (VC) is seen ubiquitously in aging blood vessels and prematurely in disease states like renal failure. It is thought to be driven by a number of systemic and local factors that lead to extra-osseous deposition of mineral in the vascular wall and valves as a common endpoint. The response of resident vascular smooth muscle cell to these dystrophic signals appears to be important in this process. Whilst in vivo models allow the observation of global changes in a pro-calcific environment, identifying the specific cells and mechanisms involved has been largely garnered from in vitro experiments, which provide added benefits in terms of reproducibility, cost, and convenience. Here we describe a 7-21 day cell culture model of calcification developed using immortalized murine vascular smooth muscle cells (MOVAS-1). This model provides a method by which vascular smooth muscle cell involvement and manipulation within a mineralizing domain can be studied.

    OBJECTTVE: To explain the association between vascular dementia and the cranial MRI manifestations, and recognize the value of cranial MRI in the early diagnosis of vascular dementia and the assessment of disease conditions.DATA SOURCES: Pubmed database was searched to identify articles about the cranial MRI manifestations of patients with vascular dementia published in English from January 1992 to June 2006 by using the key words of "MRI, vascular dementia". Others were collected by searching the name of journals and title of articles in the Chinese full-text journal database.STUDY SELECTTON: The collected articles were primarily checked, those correlated with the cranial MRI manifestations of patients with vascular dementia were selected, while the obviously irrelative ones were excluded, and the rest were retrieved manually, the full-texts were searched.DATA EXTRACTION: Totally 255 articles were collected, 41 of them were involved, and the other 214 were excluded.DATA SYNTHESIS: MRI can be taken as one of the effective methods for the early diagnosis and disease evaluation of vascular dementia. White matter lesions are the important risk factors of vascular dementia.Vascular dementia is accompanied by the atrophy of related brain sites, but further confirmation is needed to investigate whether there is significant difference. MRI can be used to quantitatively investigate the infarcted sites and sizes of patients with vascular dementia after infarction, but there is still lack of systematic investigation on the association of the infarcted sites and sizes with the cognitive function of patients with vascular dementia.CONCLUSTON: Cranial MRI can detect the symptoms of vascular dementia at early period, so that corresponding measures can be adopted to prevent and treat vascular dementia in time.

    Full Text Available Objective: Due to the ongoing civil war in Syria, numerous vascular injured patients are admitted to our hospital with gunshot wounds. In this study, patients who admitted our hospital, diagnosed with vascular trauma due to gunshot were evaluated with the respect of injury site, additional injuries, surgical interventions and outcomes. Methods: The study included 58 patients wounded in Syrian war and admitted to our hospital between 01.01.2012 and 01.09.2014. Results= There were 5.1% (n=3 female and 94.9% (n=55 male patients. Age range is 5-75 years and the average of age was identified as 28.61. In 12.1% (n=7 of patients with extensive tissue defects of the muscle-nerve-bone injury has been identified, despite the vascular interventions in these patients, 8.6% (n=5 of patients, the limb has been amputated. Totally 15.5% (n=9 of 58 operated patients died. Two patients died because of major vascular injury with intra-abdominal organ injuries. In one patient; infection induced sepsis and multi organ failure was detected. Six patients were lost due to hypovolemic shock as a result of late arriving. Conclusion: In patients admitted with gunshot vascular injury arrival time, the presence of additional injuries and the location of injury affect mortality rates.

  5. Rotationplasty with Vascular Reconstruction for Prosthetic Knee Joint Infection

    Directory of Open Access Journals (Sweden)

    Masahide Fujiki


    Full Text Available Rotationplasty is used most often as a function-preserving salvage procedure after resection of sarcomas of the lower extremity; however, it is also used after infection of prosthetic knee joints. Conventional vascular management during rotationplasty is to preserve and coil major vessels, but recently, transection and reanastomosis of the major vessels has been widely performed. However, there has been little discussion regarding the optimal vascular management of rotationplasty after infection of prosthetic knee joints because rotationplasty is rarely performed for this indication. We reviewed four patients who had undergone resection of osteosarcomas of the femur, placement of a prosthetic knee joint, and rotationplasty with vascular reconstruction from 2010 to 2013. The mean interval between prosthetic joint replacement and rotationplasty was 10.4 years and the mean interval between the diagnosis of prosthesis infection and rotationplasty was 7.9 years. Rotationplasty was successful in all patients; however, in one patient, arterial thrombosis developed and necessitated urgent surgical removal and arterial reconstruction. All patients were able to walk independently with a prosthetic limb after rehabilitation. Although there is no consensus regarding the most appropriate method of vascular management during rotationplasty for revision of infected prosthetic joints, vascular transection and reanastomosis is a useful option.

  6. Impact of implementation of a pediatric surgery fellowship on general surgery resident operative volume. (United States)

    Snyder, Rebecca A; Phillips, Sharon E; Terhune, Kyla P


    The purpose of this study was to determine the impact of the initiation of a pediatric surgery fellowship on general surgery resident operative volume at 1 major academic institution. Retrospective review of operative records obtained from the Accreditation Council for Graduate Medical Education (ACGME) general surgery resident and pediatric surgery fellow case logs. Data collected included number and type of pediatric index cases per year, number of total pediatric surgery cases per year, and number of total cases logged as primary surgeon to date. Vanderbilt University School of Medicine Department of Surgery, which has an accredited general surgery program, finishes 7 chief residents per year during the study period, and instituted a new pediatric surgery fellowship in 2007. Case logs submitted by third and fourth year general surgery residents and first and second year pediatric surgery fellows were studied. The number of pediatric attending surgeons, relative value units (RVUs), and hospital admissions increased from 2003 to 2011. The median number of pediatric index cases performed by a resident decreased after the onset of fellowship from 34 cases to 23.5 cases per year (p pediatric surgery rotation also decreased from 74 to 53 cases per year after onset of the fellowship (p surgery resident index and overall case volume in pediatric surgery. Although operative volume is only 1 measure of surgical educational value, these findings suggest that the addition of surgical fellowships affects the educational experience of general surgery residents. We recommend that residency programs establish goals and calculate any potential impact on general surgery resident case volume before initiating a new surgical fellowship.

  7. Generation of Vascular Graft Biomaterials via the Modification of Polyurethane with Hyaluronic Acid (United States)

    Ruiz, Amaliris

    Cardiovascular disease is the leading cause of mortality in the United States, necessitating surgical interventions such as small diameter (I.D. hemocompatibility, endothelialization, and vascular-appropriate mechanics, which has not been possible with other currently available materials. Moreover, the information presented herein will help the potential clinical translation of these PU-HA materials as a vascular graft product, as we aim to optimize the HA oligosaccharide content, molecular weight and incorporation method that will result in 3-D scaffolds that are hemocompatible and possess both vascular-appropriate mechanics and the ability to support a viable endothelial cell population.

  8. Review of Surgical Techniques of Experimental Renal Transplantation in Rats. (United States)

    Shrestha, Badri; Haylor, John


    Microvascular surgical techniques of renal transplant in rats have evolved over the past 5 decades to achieve successful rat renal transplant; these modifications have included surgical techniques to address the anatomic variations in the renal blood vessels and those to reduce ischemic and operation durations. Here, we review the surgical techniques of renal transplant in rats and evaluate the advantages and disadvantages of individual techniques of vascular and ureteric anastomoses. For this review, we performed a systematic literature search using relevant medical subject heading terms and included appropriate publications in the review. Since the first description of a rat model of renal transplant by Bernard Fisher and his colleagues in 1965, which used end-to-side anastomosis between the renal vein and renal artery to the recipient inferior vena cava and aorta, several vascular and ureteric anastomosis techniques have been modified. Vascular anastomosis techniques now include end-to-end anastomosis, use of donor aortic and inferior vena cava conduits, sleeve and cuff anastomoses, and application of fibrin glue. Likewise, restoration of the urinary tract can now be achieved by direct anastomosis of the donor ureter to the recipient bladder, end-to-end anastomosis between the donor and recipient ureters, and donor bladder cuff to the recipient bladder. There are advantages and disadvantages attributable to individual techniques. The range of vascular and ureteric anastomosis techniques that has emerged reflects the need for mastering more than one technique to suit the vascular anatomy of individual animals and to reduce operating time for achieving successful outcomes after renal transplant.

  9. A case report of surgical management of hemangiopericytoma at the foramen magnum. (United States)

    Arai, Nobuhiko; Takahashi, Satoshi; Mami, Hatano; Tokuda, Yukina; Yoshida, Kazunari


    Hemangiopericytoma (HPC) is a highly vascularized mesenchymal tumor known for its high rates of recurrence and metastasis. The extent of tumor removal is known to be the most trustful prognostic factor. Skull base HPCs are challenging to treat because of the difficulty of the surgical approach and proximity to vital vascular and neuronal structures. We successfully treated a case of HPC at the ventral foramen magnum through surgical gross tumor removal via a far-lateral transcondylar approach. A 38-year-old male complained of neck pain and bilateral paresthesia of his shoulders for 2 months, for which he was referred to our hospital. A magnetic resonance image (MRI) showed a 20 mm diameter mass at the ventral foramen magnum, which compressed his medulla oblongata. The tumor was gross totally removed via a far-lateral transcondylar approach. During the surgery, marked bleeding disturbed the surgical field until the main feeding artery from the direction of the dura mater was coagulated and cut. A relatively wide surgical field and a transcondylar approach were helpful to control the bleeding. The pathological examination revealed the tumor to be a HPC. After an uneventful recovery period of 9 days, the patient was discharged without neurological sequelae. We successfully and completely removed an HPC near the foramen magnum, employing a wide surgical field and a transcondylar approach to help control bleeding. When the tumor is suspected preoperatively to be a hemangiocytoma or vascular-rich tumor, a surgical approach that can secure a wide surgical field should be selected.

  10. CT in vascular pathologies

    Energy Technology Data Exchange (ETDEWEB)

    Bartolozzi, C.; Neri, E.; Caramella, D. [Diagnostic and Interventional Radiology Department of Oncology, University of Pisa, Via Roma 67, I-56100 Pisa (Italy)


    Since the introduction of helical scanners, CT angiography (CTA) has achieved an essential role in many vascular applications that were previously managed with conventional angiography. The performance of CTA is based on the accurate selection of collimation width, pitch, reconstruction spacing and scan delay, which must be modulated on the basis of the clinical issue. However, the major improvement of CT has been provided by the recent implementation of many post-processing techniques, such as multiplanar reformatting, shaded surface display, maximum intensity projections, 3D perspectives of surface and volume rendering, which simulate virtual intravascular endoscopy. The integration of the potentialities of the scanner and of the image processing techniques permitted improvement of: (a) the evaluation of aneurysms, dissection and vascular anomalies involving the thoracic aorta; (b) carotid artery stenosis; (c) aneurysms of abdominal aorta; (d) renal artery stenosis; (e) follow-up of renal artery stenting; and (f) acute or chronic pulmonary embolism. Our experience has shown that the assessment of arterial pathologies with CTA requires the integration of 3D post-processing techniques in most applications. (orig.) With 4 figs., 34 refs.

  11. Vascular dysfunction in preeclampsia. (United States)

    Brennan, Lesley J; Morton, Jude S; Davidge, Sandra T


    Preeclampsia is a complex disorder which affects an estimated 5% of all pregnancies worldwide. It is diagnosed by hypertension in the presence of proteinuria after the 20th week of pregnancy and is a prominent cause of maternal morbidity and mortality. As delivery is currently the only known treatment, preeclampsia is also a leading cause of preterm delivery. Preeclampsia is associated with maternal vascular dysfunction, leading to serious cardiovascular risk both during and following pregnancy. Endothelial dysfunction, resulting in increased peripheral resistance, is an integral part of the maternal syndrome. While the cause of preeclampsia remains unknown, placental ischemia resulting from aberrant placentation is a fundamental characteristic of the disorder. Poor placentation is believed to stimulate the release of a number of factors including pro- and antiangiogenic factors and inflammatory activators into the maternal systemic circulation. These factors are critical mediators of vascular function and impact the endothelium in distinctive ways, including enhanced endothelial oxidative stress. The mechanisms of action and the consequences on the maternal vasculature will be discussed in this review.

  12. Application of indocyanine green video angiography in surgical treatment of intracranial aneurysms

    Directory of Open Access Journals (Sweden)

    Felix Hendrik Pahl


    Full Text Available Indocyanine green (ICG video angiography has been used for several medical indications in the last decades. It allows a real time evaluation of vascular structures during the surgery. This study describes the surgical results of a senior vascular neurosurgeon. We retrospectively searched our database for all aneurysm cases treated with the aid of intraoperative ICG from 2009 to 2014. A total of 61 aneurysms in 56 patients were surgically clipped using intraoperative ICG. Clip reposition after ICG happened in 2 patients (3.2%. Generally, highly variable clip adjustment rates of 2%–38% following ICG have been reported since the introduction of this imaging technique. The application of ICG in vascular neurosurgery is still an emerging challenge. It is an adjunctive strategy which facilitates aneurismal evaluation and treatment in experienced hands. Nevertheless, a qualified vascular neurosurgeon is still the most important component of a high quality work.

    Full Text Available The basic hemodynamic abnormality in hypertension is an increased peripheral resistance that is due mainly to a decreased vascular lumen derived from structural changes in the small arteries wall, named (as a whole vascular remodeling. The vascular wall is an active, flexible, and integrated organ made up of cellular (endothelial cells, smooth muscle cells, adventitia cells, and fibroblasts and noncellular (extracellular matrix components, which in a dynamic way change shape or number, or reorganize in response to physiological and pathological stimuli, maintaining the integrity of the vessel wall in physiological conditions or participating in the vascular changes in cardiovascular diseases such as hypertension. Research focused on new signaling pathways and molecules that can participate in the mechanisms of vascular remodeling has provided evidence showing that vascular structure is not only affected by blood pressure, but also by mechanisms that are independent of the increased pressure. This review will provide an overview of the evidence, explaining some of the pathophysiologic mechanisms participating in the development of the vascular remodeling, in experimental models of hypertension, with special reference to the findings in spontaneously hypertensive rats as a model of essential hypertension, and in fructose-fed rats as a model of secondary hypertension, in the context of the metabolic syndrome. The understanding of the mechanisms producing the vascular alterations will allow the development of novel pharmacological tools for vascular protection in hypertensive disease.

    Langebæk, Rikke; Eika, Berit; Jensen, Asger Lundorff


    The surgical educational environment is potentially stressful and this can negatively affect students' learning. The aim of this study was to investigate whether veterinary students' level of anxiety is higher in a surgical course than in a non-surgical course and if pre-surgical training...... in a Surgical Skills Lab (SSL) has an anxiety reducing effect. Investigations were carried out as a comparative study and a parallel group study. Potential participants were fourth-year veterinary students who attended a surgical course (Basic Surgical Skills) and a non-surgical course (Clinical Examination...... and 28 students from 2010). Our results show that anxiety levels in veterinary students are significantly higher in a surgical course than in a non-surgical course (p...

  15. Supply and demand: Will we have enough vascular surgeons by 2030? (United States)

    Williams, Katherine; Schneider, Brandon; Lajos, Paul; Marin, Michael; Faries, Peter


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

  16. Multimodality Imaging of Normal Hepatic Transplant Vasculature and Graft Vascular Complications

    Full Text Available Orthotopic liver transplantation is an important treatment option for patients with end-stage liver disease. Advances in surgical technique, along with improvements in organ preservation and immunosuppression have improved patient outcomes. Post-operative complications, however, can limit this success. Ultrasound is the primary imaging modality for evaluation of hepatic transplants, providing real-time information about vascular flow in the graft. Graft vascular complications are not uncommon, and their prompt recognition is crucial to allow for timely graft salvage. A multimodality approach including CT angiography, MRI, or conventional angiography may be necessary in cases of complex transplant vascular anatomy or when sonography and Doppler are inconclusive to diagnose the etiologies of these complications. The purpose of this article is to familiarize radiologists with the normal post-transplant vascular anatomy and the imaging appearances of the major vascular complications that may occur within the hepatic artery, portal vein, and venous outflow tract, with an emphasis on ultrasound.

  17. Surgical bleeding in microgravity (United States)

    Campbell, M. R.; Billica, R. D.; Johnston, S. L. 3rd


    A surgical procedure performed during space flight would occur in a unique microgravity environment. Several experiments performed during weightlessness in parabolic flight were reviewed to ascertain the behavior of surgical bleeding in microgravity. Simulations of bleeding using dyed fluid and citrated bovine blood, as well as actual arterial and venous bleeding in rabbits, were examined. The high surface tension property of blood promotes the formation of large fluid domes, which have a tendency to adhere to the wound. The use of sponges and suction will be adequate to prevent cabin atmosphere contamination with all bleeding, with the exception of temporary arterial droplet streams. The control of the bleeding with standard surgical techniques should not be difficult.

  18. Surgical management of presbyopia

    Full Text Available André AM Torricelli, Jackson B Junior, Marcony R Santhiago, Samir J BecharaDivision of Ophthalmology, University of São Paulo Medical School, São Paulo, BrazilAbstract: Presbyopia, the gradual loss of accommodation that becomes clinically significant during the fifth decade of life, is a physiologic inevitability. Different technologies are being pursued to achieve surgical correction of this disability; however, a number of limitations have prevented widespread acceptance of surgical presbyopia correction, such as optical and visual distortion, induced corneal ectasia, haze, anisometropy with monovision, regression of effect, decline in uncorrected distance vision, and the inherent risks with invasive techniques, limiting the development of an ideal solution. The correction of the presbyopia and the restoration of accommodation are considered the final frontier of refractive surgery. The purpose of this paper is to provide an update about current procedures available for presbyopia correction, their advantages, and disadvantages.Keywords: presbyopia, surgical correction, treatment

  19. Additive Manufacturing of Vascular Grafts and Vascularized Tissue Constructs. (United States)

    Elomaa, Laura; Yang, Yunzhi Peter


    There is a great need for engineered vascular grafts among patients with cardiovascular diseases who are in need of bypass therapy and lack autologous healthy blood vessels. In addition, because of the severe worldwide shortage of organ donors, there is an increasing need for engineered vascularized tissue constructs as an alternative to organ transplants. Additive manufacturing (AM) offers great advantages and flexibility of fabrication of cell-laden, multimaterial, and anatomically shaped vascular grafts and vascularized tissue constructs. Various inkjet-, extrusion-, and photocrosslinking-based AM techniques have been applied to the fabrication of both self-standing vascular grafts and porous, vascularized tissue constructs. This review discusses the state-of-the-art research on the use of AM for vascular applications and the key criteria for biomaterials in the AM of both acellular and cellular constructs. We envision that new smart printing materials that can adapt to their environment and encourage rapid endothelialization and remodeling will be the key factor in the future for the successful AM of personalized and dynamic vascular tissue applications.

  1. Arthroscopic Shoulder Surgical Simulation Training Curriculum: Transfer Reliability and Maintenance of Skill Over Time. (United States)

    Dunn, John C; Belmont, Philip J; Lanzi, Joseph; Martin, Kevin; Bader, Julia; Owens, Brett; Waterman, Brian R


    Surgical education is evolving as work hour constraints limit the exposure of residents to the operating room. Potential consequences may include erosion of resident education and decreased quality of patient care. Surgical simulation training has become a focus of study in an effort to counter these challenges. Previous studies have validated the use of arthroscopic surgical simulation programs both in vitro and in vivo. However, no study has examined if the gains made by residents after a simulation program are retained after a period away from training. In all, 17 orthopedic surgery residents were randomized into simulation or standard practice groups. All subjects were oriented to the arthroscopic simulator, a 14-point anatomic checklist, and Arthroscopic Surgery Skill Eva
