Introduction: SSL introduces ergonomic challenges while establishing the critical view during dissection of the Triangle of Calot (TOC). This study investigates the use of a novel percutaneous instrument platform and MAGS in performing SSL cholecystectomy with a technique that closely mimics four-port cholecystectomy.Methods: SSL cholecystectomy was performed on four female cadavers via a 15-18-mm incision made at the umbilicus for introduction of these devices and the working port. MAGS comprises an internal effector with a retractable monopolar cautery hook coupled across the abdominal wall to an external magnet held by the surgeon. The novel grasper was introduced percutaneously in the RUQ and comprises a 3-mm transabdominal shaft mated to a 5-mm end effector intracorporeally. Retraction was accomplished using the percutaneous grasper to manipulate the fundus and a standard 5-mm grasper at the umbilicus for the infundibulum. Dissection was performed by using a combination of the MAGS and a standard Maryland dissector. Total procedure time, time from procedure start to obtain a critical view of the TOC and clipping and dividing the cystic duct/artery, time for dissection of the gallbladder from the liver bed, and thickness of the abdominal wall at the umbilicus were measured.Results: The critical view was obtained in each case, and all four procedures were completed successfully. Mean procedure time was 40 (range, 33-51) min; time from procedure start to obtaining the critical view and clipping and dividing the cystic duct/artery was 33 (range, 28-38) min, and time for dissection of the gallbladder from the liver bed was 6.7 (range, 3-13) min. The mean abdominal wall thickness was 1.9 (range, 1.5-2) cm.Conclusions: The use of a novel graspers and MAGS overcomes the limitations of SSL cholecystectomy and improves surgeon dexterity. Making SSL feel more like traditional laparoscopy will enable a wider adoption of this procedure in the community. [ABSTRACT FROM AUTHOR]

Introduction: Single-incision laparoscopic surgery (SILS) is limited by the coaxial arrangement of the instruments. A surgical robot with wristed instruments could overcome this limitation, but the arms often collide when working coaxially. This study tests a new technique of "chopstick" surgery to enable use of the robotic arms through a single incision without collision.Methods: Experiments were conducted utilizing the da Vinci S robot (Intuitive Surgical, Inc., Sunnyvale, CA) in a Fundamentals of Laparoscopic Surgery (FLS) box trainer with three laparoscopic ports (1 x 12 mm, 2 x 5 mm) introduced through a single "incision." Pilot work determined the optimal setup for SILS to be a triangular port arrangement with 2-cm trocar distance and remote center at the abdominal wall. Using this setup, five experienced robotic surgeons performed three FLS tasks utilizing either a standard robotic arm setup or the chopstick technique. The chopstick arrangement crosses the instruments at the abdominal wall so that the right instrument is on the left side of the target and the left instrument on the right. This results in separation of the robotic arms outside the box. To correct for the change in handedness, the robotic console is instructed to drive the "left" instrument with the right-hand effector and the "right" instrument with the left. Performances were compared while measuring time, errors, number of clutching maneuvers, and degree of instrument collision (Likert scale 1-4).Results: Compared with the standard setup, the chopstick configuration increased surgeon dexterity and global performance through significantly improved performance times, eliminating instrument collision, and decreasing number of camera manipulations, clutching maneuvers, and errors during all tasks.Conclusion: Chopstick surgery significantly enhances the functionality of the surgical robot when working through a small single incision. This technique will enable surgeons to utilize the robot for SILS and possibly for intraluminal or transluminal surgery. [ABSTRACT FROM AUTHOR]

Introduction: Training programs are now more than ever seeking ways to promote recruitment and retention of a diverse resident workforce. The goal of this study was to examine how gender and ethnic identities affect applicant attraction to surgery training programs., Methods: Applicants to general surgery residency in 2018 to 2019 completed a 31-item assessment measuring preferences for training program characteristics and attributes. Differences in preferences across candidate gender and ethnicity were investigated. Factor analyses and analysis of variance (ANOVA) were used to explore these differences., Results: 1491 unique applicants to 7 residency programs completed the assessment, representing 67% of all applicants to general surgery during the 2018 to 2019 season. Women preferred training programs that had high levels of social support (p < 0.001), were less traditional (p < 0.001), and with less turbulence (p < 0.05). Non-white candidates reported greater preference for programs with higher levels of established academics (p < 0.001), clinical experiences (p < 0.001), social support (p < 0.05), traditionalism (p < 0.001), flexibility (p < 0.001), and innovation (p < 0.001)., Conclusions: Organizational efforts to attract and retain a diverse workforce may benefit from considering the aspects of work that align with female and underrepresented minority preferences., (Copyright © 2021 Association of Program Directors in Surgery.

Background: Published needs analyses of rural surgeons have identified a need for training in the endoscopic management of non-variceal upper gastrointestinal bleeding (NVUGIB). The study aim was to survey rural surgeons regarding their requirements and preferences for a simulation model on which they could rehearse the endoscopic management of NVUGIB., Methods: Rural surgeons were contacted via the American College of Surgery Advisory Council listserv and invited to complete an online survey., Results: A total of 66 responses were received, representing all 4 US regional divisions. Seventy-seven percent of respondents perform > 100 endoscopy cases per year. A majority have no experience with simulation models (77%), citing cost, time, and access to training courses as the three most limiting factors. Thirty-three percent lacked confidence in managing UGIBs, and 73% were interested in receiving additional training. Preference analysis revealed that respondents preferred a portable simulation model (81%) that costs between $500 and $1000 (46%), and requires 1-2 weeks of training (34%). Verbal feedback from an expert was viewed as the most helpful type of feedback (61%)., Conclusion: Rural surgeons frequently perform flexible endoscopy in their practice and are interested in further training for the endoscopic management of NVUGIB. These results will be used to develop a simulation platform for training in the endoscopic management of NVUGIB that meets rural surgeons' needs.

Objective: The current, unprecedented pace of change in medicine challenges healthcare professionals to stay up-to-date. To more effectively disseminate new surgical or endoscopic techniques a modern paradigm of training is required. Our aim was to develop a curricular framework for complex techniques that provide logistical challenges to training in order to increase safe, effective use. We use colonic endoscopic submucosal dissection (cESD) as an example., Design: Curriculum development followed a multistep process representing best practice in training and education. First, a Clinical Needs Assessment established the demand for/sustainability of training. A Training Needs Analysis then identified the knowledge, skills, and attitudes required to perform cESD. A modified Delphi process defined desired learner characteristics, identified indications/contraindications to cESD, and developed a procedural task list. A pilot simulation program gathered feedback from cESD faculty experts and learners. Finally, a Behavioral Observation Scale was developed as a clinical assessment tool to assess procedural performance., Setting: The Houston Methodist Institute for Technology, Innovation and Education., Participants: The first Curriculum Design Summit engaged 11 clinical SMEs, 4 education and training SMEs, 3 market development SMEs, and 1 medical device research and design engineer. The second Curriculum Design Summit engaged 10 clinical SMEs, 4 education and training SMEs, and 4 market development SMEs. We also engaged 12 Learner SMEs at both hands-on pilot courses who currently are training to perform cESD., Results: Desired learner criteria were defined (e.g., in practice >2 years, available case volume ≥25/year) to ensure ability and motivation of learners. Lesions were classified by (1) suitability for cESD (Clinical T1N0M0, Paris 0-IIa +1s  > 2 cm, 0-IIc + IIa, 0-IIc), and (2) suitability for trainee experience level. A comprehensive cESD task list was constructed and an assessment tool created based on SME review of key characteristics (e.g., comprehensiveness and usability)., Conclusion: We describe a comprehensive framework to develop educational curricula for complex surgical/endoscopic techniques with logistical challenges. To illustrate the sustainability of this training model and impact on patient outcomes, we plan to further develop and implement this program nationally., (Copyright © 2020 Association of Program Directors in Surgery.

Background: Achalasia is an uncommon disease treated by decreasing the lower esophageal sphincter resting pressure. This study compared the safety and efficacy of esophago-gastric myotomy via laparoscopic, robotic, and per-oral endoscopic approaches., Methods: A retrospective review of data on patients with achalasia or other esophageal dysmotility disorder undergoing laparoscopic, robotically assisted, or per-oral endoscopic myotomy (POEM) procedures between 2013 and 2017 was performed. Patient demographics, comorbidities, procedure details, length of stay, 30-day readmission rate, and combined technical complication (full-thickness injury, conversion to open, and delayed perforation) were compared. Multiple logistic regression analysis was performed to determine which factors contributed to combined technical complication., Results: There were 171 patients who underwent esophago-gastric myotomy with 161 (94.2%) having achalasia. There were 40 laparoscopic Heller myotomies with partial fundoplication, 44 robotic Heller myotomies with partial fundoplication, and 87 POEM procedures performed during the study period. Baseline statistical differences were found among the groups in regard to gastroesophageal reflux symptoms, arrhythmia, hypertension, and congestive heart failure. Laparoscopic Heller myotomy had significantly higher combined technical complications (7, 17.5%) compared to robotically assisted Heller myotomy (0, 0%) and POEM (1, 1.1%). Multivariate analysis showed that laparoscopic Heller myotomy (OR 32.22; 95% CI 2.66, 389.83; p = 0.01), myocardial infarction (OR 27.94; 95% CI 1.66, 471.10; p = 0.02), and history of smoking (OR 8.87; 95% CI 1.29, 61.15; p = 0.03) were risks for developing combined technical complications., Conclusion: Robotically assisted Heller myotomy and POEM are safe and efficacious treatments for achalasia with lower rates of technical complications compared to laparoscopic Heller myotomy. With the advancements in endoscopic instruments and robotic surgery, POEM and robotically assisted Heller myotomy should be considered in the treatment of achalasia and esophageal dysmotility disorders.

Background: Slow adoption of colonic ESD (cESD) in the US is multifactorial due to: lack of clinical training construct (e.g., gastric ESD in Japan), complication risks, and technical difficulty. More than 28,000 patients/year undergo colonic resection for benign lesions that could be managed effectively with cESD. Selected patients could avoid surgery if procedural adoption of cESD increased due to more accessible training. Current US cESD training is scarce, and existing programs are piecemeal. There is a need to develop an effective national training program for practicing endoscopists. A prerequisite to training development is a comprehensive task list delineating procedural steps. The aim of this work was to describe an evidence-based method of deconstructing cESD into the essential steps to provide a task list to guide teaching and assessment., Methods: Subject-matter experts (SMEs) performed a literature review to create an initial procedural step list. Eleven clinical cESD SMEs and four educational SMEs formed a 'cESD Working Group' to develop consensus regarding steps. Through a two-stage modified Delphi process, a consensus on a comprehensive standard cESD deconstructed task list was reached. The aim was to standardize cESD teaching to efficiently bring a novice to safe performance., Results: A literature review identified eight initial cESD steps. First-round Delphi consensus was gained on seven steps. Semi-structured focus group discussions resulted in consensus on a modified version of 7 of the initial steps, with addition of two steps. Consensus on procedural actions needed to perform each step was achieved after the hands-on laboratory. The final result was a ten-step deconstructed task list for standard cESD., Conclusion: The development of a standardized cESD procedural task list provides a foundation to safely and efficiently teach cESD to practicing endoscopists. This list can be used to develop a training pathway to increase procedural adoption. Selected patients currently undergoing colonic resections could benefit from increased adoption of cESD.

Introduction: While better technical performance correlates with improved outcomes, there is a lack of procedure-specific tools to perform video-based assessment (VBA). SAGES is developing a series of VBA tools with enough validity evidence to allow reliable measurement of surgeon competence. A task force was established to develop a VBA tool for laparoscopic fundoplication using an evidence-based process that can be replicated for additional procedures. The first step in this process was to seek content validity evidence., Methods: Forty-two subject matter experts (SME) in laparoscopic fundoplication were interviewed to obtain consensus on procedural steps, identify potential variations in technique, and to generate an inventory of required skills and common errors. The results of these interviews were used to inform creation of a task inventory questionnaire (TIQ) that was delivered to a larger SME group (n = 188) to quantify the criticality and difficulty of the procedural steps, the impact of potential errors associated with each step, the technical skills required to complete the procedure, and the likelihood that future techniques or technologies may change the presence or importance of any of these factors. Results of the TIQ were used to generate a list of steps, skills, and errors with strong validity evidence., Results: Initial SMEs interviewed included fellowship program directors (45%), recent fellows (24%), international surgeons (19%), and highly experienced super SMEs with quality outcomes data (12%). Qualitative analysis of interview data identified 6 main procedural steps (visualization, hiatal dissection, fundus mobilization, esophageal mobilization, hiatal repair, and wrap creation) each with 2-5 sub steps. Additionally, the TIQ identified 5-10 potential errors for each step and 11 key technical skills required to perform the procedure. Based on the TIQ, the mean criticality and difficulty scores for the 11/21 sub steps included in the final scoring rubric is 4.66/5 (5 = absolutely essential for patient outcomes) and 3.53/5 (5 = difficulty level requires significant experience and use of alternative strategies to accomplish consistently), respectively. The mean criticality and frequency scores for the 9/11 technical skills included is 4.51/5 and 4.51/5 (5 = constantly used ≥ 80% of the time), respectively. The mean impact score of the 42/47 errors incorporated into the final rubric is 3.85/5 (5 = significant error that is unrecoverable, or even if recovered, likely to have a negative impact on patient outcome)., Conclusions: A rigorous, multi-method process has documented the content validity evidence for the SAGES video-based assessment tool for laparoscopic fundoplication. Work is ongoing to pilot the assessment tool on recorded fundoplication procedures to establish reliability and further validity evidence.

Purpose: Use of the United States Medical Licensing Examination (USMLE) for residency selection has been criticized for its inability to predict clinical performance and potential bias against underrepresented minorities (URMs). This study explored the impact of altering traditional USMLE cutoffs and adopting more evidence-based applicant screening tools on inclusion of URMs in the surgical residency selection process., Method: Multimethod job analyses were conducted at 7 U.S. general surgical residency programs during the 2018-2019 application cycle to gather validity evidence for developing selection assessments. Unique situational judgment tests (SJTs) and scoring algorithms were created to assess applicant competencies and fit. Programs lowered their traditional USMLE Step 1 cutoffs and invited candidates to take their unique SJT. URM status (woman, racial/ethnic minority) of candidates who would have been considered for interview using traditional USMLE Step 1 cutoffs was compared with the candidate pool considered based on SJT performance., Results: A total of 2,742 general surgery applicants were invited to take an online SJT by at least 1 of the 7 programs. Approximately 35% of applicants who were invited to take the SJT would not have met traditional USMLE Step 1 cutoffs. Comparison of USMLE-driven versus SJT-driven assessment results demonstrated statistically different percentages of URMs recommended, and including the SJT allowed an average of 8% more URMs offered an interview invitation (P < .01)., Conclusions: Reliance on USMLE Step 1 as a primary screening tool precludes URMs from being considered for residency positions at higher rate than non-URMs. Developing screening tools to measure a wider array of candidate competencies can help create a more equitable surgical workforce.

Introduction: We describe a multimethod, multi-institutional approach documenting future competencies required for entry into surgery training., Methods: Five residency programs involved in a statewide collaborative each provided 12 to 15 subject matter experts (SMEs) to participate. These SMEs participated in a 1-hour semistructured interview with organizational psychologists to discuss program culture and expectations, and rated the importance of 20 core competencies derived from the literature for candidates entering general surgery training within the next 3 to 5 years (1 = importance decreases significantly; 3 = importance stays the same; 5 = importance increases significantly)., Results: Seventy-three SMEs across 5 programs were interviewed (77% faculty; 23% resident). All competencies were rated to be more important in the next 3 to 5 years, with team orientation (3.87 ± 0.81), communication (3.82 ± 0.79), team leadership (3.81 ± 0.82), feedback receptivity (3.79 ± 0.76), and professionalism (3.76 ± 0.89) rated most highly., Conclusions: These findings suggest that the competencies desired and required among future surgery residents are likely to change in the near future., (Copyright © 2019 Association of Program Directors in Surgery.

Introduction: Residency applicant screening practices are inefficient and costly. However, programs may not consider using alternative assessments for fear that candidates will be "turned off" by additional hurdles in the application process. This study explores the relationship between candidate completion of preinterview screening assessments, applicant examination scores, and program factors., Methods: Applicants to any of 7 general surgery residency programs were invited to take a preinterview online assessment. Program characteristics and applicant United States Medical Licensing Exams scores were considered in relation to each program's assessment completion rate., Results: A total of 2960 applicants were invited to take the assessment and 97% (2870/2960) completed it. Program completion rates ranged from 95% to 98%. There was no correlation between program characteristics and applicant completion rates. Candidates who did not complete the assessment had significantly lower United States Medical Licensing Exams scores., Conclusions: Incorporating preinterview assessments to objectively measure candidate competencies and fit will not detract applicants from a general surgery program., (Copyright © 2019 Association of Program Directors in Surgery.

Background: Acute diverticulitis (AD) presents a unique diagnostic and therapeutic challenge for general surgeons. This collaborative project between EAES and SAGES aimed to summarize recent evidence and draw statements of recommendation to guide our members on comprehensive AD management., Methods: Systematic reviews of the literature were conducted across six AD topics by an international steering group including experts from both societies. Topics encompassed the epidemiology, diagnosis, management of non-complicated and complicated AD as well as emergency and elective operative AD management. Consensus statements and recommendations were generated, and the quality of the evidence and recommendation strength rated with the GRADE system. Modified Delphi methodology was used to reach consensus among experts prior to surveying the EAES and SAGES membership on the recommendations and likelihood to impact their practice. Results were presented at both EAES and SAGES annual meetings with live re-voting carried out for recommendations with < 70% agreement., Results: A total of 51 consensus statements and 41 recommendations across all six topics were agreed upon by the experts and submitted for members' online voting. Based on 1004 complete surveys and over 300 live votes at the SAGES and EAES Diverticulitis Consensus Conference (DCC), consensus was achieved for 97.6% (40/41) of recommendations with 92% (38/41) agreement on the likelihood that these recommendations would change practice if not already applied. Areas of persistent disagreement included the selective use of imaging to guide AD diagnosis, recommendations against antibiotics in non-complicated AD, and routine colonic evaluation after resolution of non-complicated diverticulitis., Conclusion: This joint EAES and SAGES consensus conference updates clinicians on the current evidence and provides a set of recommendations that can guide clinical AD management practice.

Interest in the use of simulation for acquiring, maintaining, and assessing skills in GI endoscopy has grown over the past decade, as evidenced by recent American Society for Gastrointestinal Endoscopy (ASGE) guidelines encouraging the use of endoscopy simulation training and its incorporation into training standards by a key accreditation organization. An EndoVators Summit, partially supported by a grant from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health, (NIH) was held at the ASGE Institute for Training and Technology from November 19 to 20, 2017. The summit brought together over 70 thought leaders in simulation research and simulator development and key decision makers from industry. Proceedings opened with a historical review of the role of simulation in medicine and an outline of priority areas related to the emerging role of simulation training within medicine broadly. Subsequent sessions addressed the summit's purposes: to review the current state of endoscopy simulation and the role it could play in endoscopic training, to define the role and value of simulators in the future of endoscopic training and to reach consensus regarding priority areas for simulation-related education and research and simulator development. This white paper provides an overview of the central points raised by presenters, synthesizes the discussions on the key issues under consideration, and outlines actionable items and/or areas of consensus reached by summit participants and society leadership pertinent to each session. The goal was to provide a working roadmap for the developers of simulators, the investigators who strive to define the optimal use of endoscopy-related simulation and assess its impact on educational outcomes and health care quality, and the educators who seek to enhance integration of simulation into training and practice., (Copyright © 2019.

Introduction: As current screening methods for selecting surgical trainees are receiving increasing scrutiny, development of a more efficient and effective selection system is needed. We describe the process of creating an evidence-based selection system and examine its impact on screening efficiency, faculty perceptions, and improving representation of underrepresented minorities., Methods: The program partnered with an expert in organizational science to identify fellowship position requirements and associated competencies. Situational judgment tests, personality profiles, structured interviews, and technical skills assessments were used to measure these competencies. The situational judgment test and personality profiles were administered online and used to identify candidates to invite for on-site structured interviews and skills testing. A final rank list was created based on all data points and their respective importance. All faculty completed follow-up surveys regarding their perceptions of the process. Candidate demographic and experience data were pulled from the application website., Results: Fifty-five of 72 applicants met eligibility requirements and were invited to take the online assessment, with 50 (91%) completing it. Average time to complete was 42 ± 12 minutes. Eighteen applicants (35%) were invited for on-site structured interviews and skills testing-a greater than 50% reduction in number of invites compared to prior years. Time estimates reveal that the process will result in a time savings of 68% for future iterations, compared to traditional methodologies. Fellowship faculty (N = 5) agreed on the value and efficiency of the process. Underrepresented minority candidates increased from an initial 70% to 92% being invited for an interview and ranked using the new screening tools., Discussion: Applying selection science to the process of choosing surgical trainees is feasible, efficient, and well-received by faculty for making selection decisions.

Introduction: Screening practices for selecting surgery trainees have been criticized for subjectivity, inefficiency, and inability to predict performance. This study explored applicant perceptions to an untraditional selection process., Methods: Fellowship applicants completed an online assessment containing 26 situational judgment test (SJT) items and a 108-item personality profile. High-performing candidates participated in on-site structured interviews and skills testing. Upon completion of all interviews, but before match results were available, an anonymous, online survey was sent to all applicants. The survey asked about perceptions of the selection system along dimensions of procedural justice theory on a 1 (strongly disagree) to 5 (strongly agree) scale., Results: Twenty-one of 51 applicants completed the survey. Those invited for an interview (N = 12) had more favorable perceptions about communication (3.50 ± 1.38 versus 2.00 ± 0.82,p < 0.05), opportunity to perform (3.33 ± 1.56 versus 1.29 ± 0.49,p < 0.01), fairness (4.50 ± 0.80 versus 3.43 ± 1.40,p < 0.05) and gaining more insight (4.25 ± 1.22 versus 2.29 ± 1.60,p < 0.01) compared to applicants not invited. Content (4.21 ± 0.86) and consistency (4.79 ± 0.42) means were similar., Conclusions: These results suggest that applicant perceptions are directly related to how well they perform in the selection procedure., (Copyright © 2018 Elsevier Inc.

Objective: We describe a half-day faculty development course designed to equip surgical educators with evidence-based teaching frameworks shown to promote learning in the operating room (OR). We hypothesize that participating faculty will deliver improved instruction as perceived by residents., Methods: Residents anonymously rated faculty teaching behaviors among whom they had recently worked in the OR (minimum 3 cases in preceding 6 months) using the Briefing - Intraoperative teaching - Debriefing Assessment Tool (BIDAT; 1 = never, 5 = always). Faculty then attended a half-day course. The curriculum was based on the "briefing-intraoperative teaching-debriefing" framework. Discussion and practice centered on goal setting, performance-enhancing instruction, dual task interference, and feedback. After the course, residents again evaluated the faculty. Paired-samples and independent-samples t tests were used to analyze pre and post course changes and differences between groups, respectively., Results: Nineteen faculty completed the course. Associate professors (N = 4) demonstrated improved briefing (4.32 ± 0.48 → 4.76 ± 0.45, P < 0.01), debriefing (4.30 ± 0.29 → 4.77 ± 0.43, P < 0.01), and total teaching (4.38 ± 0.78 → 4.79 ± 0.39, P < 0.05). No significant changes were observed among assistant (N = 9) or full professors (N = 6). All 3 faculty members who served as course co-instructors, regardless of rank, improved significantly in briefing (4.42 ± 0.22 → 4.98 ± 0.29, P < 0.05), debriefing (4.27 ± 0.23 → 4.98 ± 0.29, P < 0.04), and total teaching (4.37 ± 0.21 → 4.99 ± 0.02, P < 0.05). Faculty with baseline teaching scores in the bottom quartile improved teaching behaviors in all phases of instruction (P < 0.05). Teaching scores over the same period did not change among faculty who did not attend., Conclusions: A half-day course aimed at enhancing intraoperative instruction can contribute to resident-perceived improvement in structured teaching behavior among participating faculty. Initiatives directed at intraoperative instruction might be best targeted towards midlevel faculty with established technical expertise who are motivated to expand teaching efforts and those who have low levels of baseline teaching scores.

Background: The Fundamentals of Endoscopic Surgery (FES) certification has recently been mandated by the American Board of Surgery but best methods for preparing for the exam are lacking. Our previous work demonstrated a 40% pass rate for PGY5 residents in our program. The purpose of this study was to determine the effectiveness of a proficiency-based skills and cognitive curriculum for FES certification., Methods: Residents who agreed to participate (n = 15) underwent an orientation session, followed by skills pre-testing using three previously described models (Trus, Operation targeting task, and Kyoto) as well as the actual FES skills exam (vouchers provided by the FES committee). Participants then trained to proficiency on all three models for the skills curriculum and completed the FES online didactic material for the cognitive curriculum. Finally, participants post-tested on the models and took the actual FES certification exam. Values are mean ± SD; p < 0.05 was considered significant., Results: Of 15 residents who participated, 8 (53%) passed the FES skills exam at baseline. Participants required 2.7 ± 1.3 h to achieve proficiency on the models and approximately 3 h to complete the cognitive curriculum. At post-test, 14 (93%, vs. pre-test 53%, p = 0.041) passed the FES skills exam. 14 (93%) passed the FES cognitive exam and 13/15 (87%) passed both the skills and cognitive exam and achieved FES certification., Conclusions: Our traditional clinical endoscopy curricula were not sufficient for senior residents to pass the FES exam. Implementation of a proficiency-based flexible endoscopy curriculum using bench-top models and the FES online materials was feasible and effective for the majority of learners. Importantly, with a modest amount of additional training, 87% of our trainees were able to pass the FES examination, which represents a significant improvement for our program. We expect that additional refinements of this curriculum may yield even better results for preparing future residents for the FES examination.

Background: The American health care system faces deficits in quality and quantity of surgeons. SAGES is a major stakeholder in surgical fellowship training and is responsible for defining the curriculum for the Advanced GI/MIS fellowship. SAGES leadership is actively adapting this curriculum., Methods: The process of reform began in 2014 through a series of iterative meetings and discussions. A working group within the Resident and Fellow Training Committee reviewed case log data from 2012 to 2015. These data were used to propose new criteria designed to provide adequate exposure to core content. The working group also proposed using video assessment of an MIS case to provide objective assessment of competency., Results: Case log data were available for 326 fellows with a total of 85,154 cases logged (median 227 per fellow). The working group proposed new criteria starting with minimum case volumes for five defined categories including foregut (20), bariatrics (25), inguinal hernia (10), ventral hernia (10), and solid organ/colon/thoracic (10). Fellows are expected to perform an additional 75 complex MIS cases of any category for a total of 150 required cases overall. The proposal also included a minimum volume of flexible endoscopy (50) and submission of an MIS foregut case for video assessment. The new criteria more clearly defined which surgeon roles count for major credit within individual categories. Fourteen fellowships volunteered to pilot these new criteria for the 2017-2018 academic year., Conclusions: The new SAGES Advanced GI/MIS fellowship has been crafted to better define the core content that should be contained in these fellowships, while still allowing sufficient heterogeneity so that individual learners can tailor their training to specific areas of interest. The criteria also introduce innovative, evidence-based methods for assessing competency. Pending the results of the pilot program, SAGES will consider broad implementation of the new fellowship criteria.

Importance: The ability to identify candidates who will thrive and successfully complete their residency is especially critical for general surgery programs., Objective: To assess the extent to which 3 screening tools used extensively in industrial selection settings-emotional intelligence (EQ), personality profiles, and situational judgment tests (SJTs)-could identify successful surgery residents., Design, Setting, and Participants: In this analysis, personality profiles, EQ assessments, and SJTs were administered from July through August 2015 to 51 postgraduate year 1 through 5 general surgery residents in a large general surgery residency program. Associations between these variables and residency performance were investigated through correlation and hierarchical regression analyses., Interventions: Completion of EQ, personality profiles, and SJT assessments., Main Outcomes and Measures: Performance in residency as measured by a comprehensive performance metric. A score of zero represented a resident whose performance was consistent with that of their respective cohort's performance; below zero, worse performance; and greater than zero, better performance., Results: Of the 61 eligible residents, 51 (84%) chose to participate and 22 (43%) were women. US Medical Licensing Examination Step 1 (USMLE1), but not USMLE2, emerged as a significant factor (t2,49 = 1.98; β = 0.30; P = .03) associated with overall performance. Neither EQ facets nor overall EQ offered significant incremental validity over USMLE1 scores. Inclusion of the personality factors did not significantly alter the test statistic and did not explain any additional portion of the variance. By contrast, inclusion of SJT scores accounted for 15% more of the variance than USMLE1 scores alone, resulting in a total of 25% of the variance explained by both USMLE1 and SJT scores (F2,57 = 7.47; P = .002). Both USMLE1 (t = 2.21; P = .03) and SJT scores (t = 2.97; P = .005) were significantly associated with overall resident performance., Conclusions and Relevance: This study found little support for the use of EQ assessment and only weak support for some distinct personality factors (ie, agreeableness, extraversion, and independence) in surgery resident selection. Performance on the SJT was associated with overall resident performance more than traditional cognitive measures (ie, USMLE scores). These data support further exploration of these 2 screening assessments on a larger scale across specialties and institutions.

Background: The selection of high-quality applicants is critical to the future of surgery. However, it is unclear if current practices meet industry criteria of a successful selection system, as measured by administrative efficiency and performance and attrition of those selected., Methods: We performed a modified systematic review process to gain an understanding of current selection processes, remediation practices, and attrition rates in surgery residency training programs in the United States. We also conducted semistructured interviews with local residency program directors and coordinators to obtain a specific snapshot of the amount of time and resources dedicated to these activities in various sized programs. The associated financial costs of these activities are also presented., Results: The administrative costs for current residency selection processes are substantial, ranging from $45,000 to $148,000 for each program per year. Approximately 30% of residents require at least 1 remediation intervention, costing programs $3400 to $5300 per episode, and typically involve concerns around nontechnical skills. Attrition rates range from 20% to 40%., Conclusions: This review suggests that additional methodologies may allow surgery residency programs to identify best-fit candidates more efficiently and effectively, while also decreasing remediation and attrition rates. Possible solutions include incorporation of structured interviews, personality inventories, and situational judgment tests. Resources dedicated to current interview practices, remediation efforts, and attrition management can be redirected to support these methodologies. By applying the science of selection and assessment to the recruitment process, programs may be able to make more data-driven decisions to identify candidates who will be successful at their institution., (Copyright © 2017 Association of Program Directors in Surgery.

Background: Metabolic syndrome (MetS) entails the simultaneous presence of a constellation of dangerous risk factors including obesity, diabetes, hypertension, and dyslipidemia. The prevalence of MetS in Western society continues to rise and implies an elevated risk for surgical complications and/or poor surgical outcomes within the affected population., Objective: To assess the risks and outcomes of multi-morbid patients with MetS undergoing open ventral hernia repair., Setting: Multi-institutional case-control study in the United States., Methods: The American College of Surgeons National Surgical Quality Improvement Program database was sampled for patients undergoing initial open ventral hernia repair from 2012 through 2014 and then stratified into 2 cohorts based on the presence or absence of MetS. Statistical analyses were performed to evaluate preoperative co-morbidities, intraoperative details, and postoperative morbidity and mortality to identify risk factors for adverse outcomes., Results: Mean age (61.0 versus 56.0 yr, P<.001), body mass index (39.2 versus 31.1, P<.001), and prevalence of co-morbidities of multiple organ systems were significantly higher (P<.001) in the MetS cohort compared to control. Patients with MetS received higher American Society of Anesthesiologists classifications (81.0% versus 43.1% class 3 or higher, P<.001), were more likely to require operation as emergency cases (11.4% versus 7.2%, P<.001), required longer operative times (103 versus 87 min, P<.001), had longer hospitalizations (3.5 versus 2.4 d, P<.001), and had more contaminated wounds (15.9% versus 12.0% class 2 or higher, P<.001). Overall, they had more medical (7.5% versus 4.2%, P<.001), and surgical complications (9.7% versus 5.4%, P<.001), experienced more readmissions (8.3% versus 5.7%, P<.001) and reoperations (3.4% versus 2.5%, P<.001), and were at higher risk for eventual death (.8% versus .5%, P=.008)., Conclusions: The presence of MetS is related to a multitude of unfavorable outcomes and increased mortality after open ventral hernia repair compared with a non-MetS control group. MetS is a useful marker for high operative risk in a population that is generally prone to obesity and its associated diseases., (Copyright © 2018 American Society for Bariatric Surgery.

Background: The role of simulation-based education continues to expand exponentially. To excel in this environment as a surgical simulation leader requires unique knowledge, skills, and abilities that are different from those used in traditional clinically-based education., Methods: Leaders in surgical simulation were invited to participate as discussants in a pre-conference course offered by the Association for Surgical Education. Highlights from their discussions were recorded., Results: Recommendations were provided on topics such as building a simulation team, preparing for accreditation requirements, what to ask for during early stages of development, identifying tools and resources needed to meet educational goals, expanding surgical simulation programming, and building educational curricula., Conclusion: These recommendations provide new leaders in simulation with a unique combination of up-to-date best practices in simulation-based education, as well as valuable advice gained from lessons learned from the personal experiences of national leaders in the field of surgical simulation and education., (Copyright © 2017 Elsevier Inc.

Purpose: This paper presents a method to use the Smart Trocars-our new surgical instrument recognition system-or any accurate localization system of surgical instrument for acquiring intraoperative surface data. Complex laparoscopic surgeries need a proper guidance system which requires registering the preoperative data from a CT or MRI scan to the intraoperative patient state. The Smart Trocar can be used to localize the instruments when it comes to contact with the soft tissue surface., Method: Two successive views through the laparoscope at different angles with the 3D localization of a fixed tool at one single location using the Smart Trocars can point out visible features during the surgery and acquire their location in 3D to provide a depth map in the region of interest. In other words, our method transforms a standard laparoscope system into a system with three-dimensional registration capability., Result: This method was initially tested on a simulation for uncertainty assessment and then on a rigid model for verification with an accuracy within 2 mm distance. In addition, an in vivo experiment on pig model was also conducted to investigate how the method might be used during a physiologic respiratory cycle., Conclusion: This method can be applied in a large number of surgical applications as a guidance system on its own or in conjunction with other navigation techniques. Our work encourages further testing with realistic surgical applications in the near future.

Background: Primary laparoscopic hiatal repair with fundoplication is associated with a high recurrence rate. We wanted to evaluate the potential risks posed by routine use of onlay-mesh during hiatal closure, when compared to primary repair., Methods: Utilizing single-institutional database, we identified patients who underwent primary laparoscopic hiatal repair from January 2005 through December 2014. Retrospective chart review was performed to determine perioperative morbidity and mortality. Long-term results were assessed by sending out a questionnaire. Results were tabulated and patients were divided into 2 groups: fundoplication with hiatal closure + absorbable or non-absorbable mesh and fundoplication with hiatal closure alone., Results: A total of 505 patients underwent primary laparoscopic fundoplication. Mesh reinforcement was used in 270 patients (53.5%). There was no significant difference in the 30-day perioperative outcomes between the 2 groups. No clinically apparent erosions were noted and no mesh required removal. Standard questionnaire was sent to 475 patients; 174 (36.6%) patients responded with a median follow-up of 4.29 years. Once again, no difference was noted between the 2 groups in terms of dysphagia, heartburn, long-term antacid use, or patient satisfaction. Of these, 15 patients (16.9%, 15/89) in the 'Mesh' cohort had symptomatic recurrence as compared to 19 patients (22.4%, 19/85) in the 'No Mesh' cohort (p = 0.362). A reoperation was necessary in 6 patients (6.7%) in the 'Mesh' cohort as compared to 3 patients (3.5%) in the 'No Mesh' cohort (p = 0.543)., Conclusions: Onlay-mesh use in laparoscopic hiatal repair with fundoplication is safe and has similar short and long-term results as primary repair.

Introduction: Previous work has shown that up to 30% of graduating surgery residents fail the fundamentals of endoscopic surgery (FES) exam. This study investigated the extent to which FES pass rates differ in a specific sample of individuals who have chosen a career in GI surgery and to examine the relationships between FES performance and confidence in performing flexible endoscopy., Methods: Fellows attending the 2016 SAGES Flexible Endoscopy Course were invited to complete the FES manual skills examination. Participants also provided survey responses examining demographics, fellowship type, endoscopy curricula in residency, previous endoscopic case volume, confidence in performing endoscopy, and future practice plans., Results: Twenty-nine (age: 32.24 ± 3.24; 72% men) fellows completed the FES skills examination. Reported fellowships were MIS/Bariatric (41.4%), MIS (24.1%), bariatric (13.8%), flexible endoscopy (6.9%), Advanced GI (6.9%), and MIS/bariatric/flexible endoscopy (6.9%). Almost half (41.4%) had previously participated in a simulation curricula, with 20.7% completing a didactic endoscopy curriculum. Fellows reported performing an average of 110 ± 109.48 EGDs and 77.44 ± 58.80 colonoscopies. The majority (96.4%) indicated that they will perform endoscopy at least occasionally in practice. Overall pass rate was 60%. Previous endoscopy experience did not correlate with overall FES examination scores. However, confidence performing EGDs (r = 0.57, p < 0.01), colonoscopies (r = 0.45, p < 0.05), polypectomy (r = 0.52, p < 0.01), and PEGs (r = 0.46, p < 0.05) did., Conclusions: These data support existing research suggesting that current flexible endoscopy training in residency may be insufficient for trainees to pass the FES examination, and that failure rates hold true even for this select group of trainees who have chosen a profession in GI surgery and intend to use endoscopy in practice.

Introduction: Guidance on how to train faculty to conduct structured interviews and implement them into current screening processes is lacking. The goal of this study is to describe a structured interview training program designed specifically for surgeons and examine its effectiveness., Methods: Faculty involved in advanced surgical fellowship interviews completed a 20-item knowledge assessment and video-based applicant interview ratings before taking a half-day course on conducting structured interviews. The course consisted of evidence-based strategies and methods for conducting structured interviews, asking questions, and rating applicants in a highly interactive format. After the course, faculty again completed the knowledge assessment and provided ratings for 3 video-based applicant interviews., Results: All faculty members (N = 5) responsible for selecting fellows in minimally invasive and bariatric surgery completed the training. Faculty had an average of 15.8 ± 9.12 years in practice. Average performance on the precourse knowledge assessment was 35% ± 6.12% and the group was unable to achieve acceptable agreement for applicant interview scores for any of the competencies assessed. After the course, faculty demonstrated significant improvements (p < 0.01) on the knowledge assessment, more than doubling their scores on the pretest with average scores of 80% ± 9.35%. Faculty also improved their interrater agreement of applicant competency, with 80% of the applicant interview ratings within 2 points of each other., Conclusions: Implementation of a half-day course designed to teach principles and skills around structured interviewing and assessment demonstrated significant improvements in both interviewing knowledge and interrater agreement. These findings support the time and resources required to develop and implement a structured interview training program for surgeons for the postgraduate admissions process., (Copyright © 2018 Association of Program Directors in Surgery.

Background: Despite the significant expense of OR time, best practice achieves only 70% efficiency. Compounding this problem is a lack of real-time data. Most current OR utilization programs require manual data entry. Automated systems require installation and maintenance of expensive tracking hardware throughout the institution. This study developed an inexpensive, automated OR utilization system and analyzed data from multiple operating rooms., Study Design: OR activity was deconstructed into four room states. A sensor network was then developed to automatically capture these states using only three sensors, a local wireless network, and a data capture computer. Two systems were then installed into two ORs, recordings captured 24/7. The SmartOR recorded the following events: any room activity, patient entry/exit time, anesthesia time, laparoscopy time, room turnover time, and time of preoperative patient identification by the surgeon., Results: From November 2014 to December 2015, data on 1003 cases were collected. The mean turnover time was 36 min, and 38% of cases met the institutional goal of ≤30 min. Data analysis also identified outlier cases (>1 SD from mean) in the domains of time from patient entry into the OR to intubation (11% of cases) and time from extubation to patient exiting the OR (11% of cases). Time from surgeon identification of patient to scheduled procedure start time was 11 min (institution bylaws require 20 min before scheduled start time), yet OR teams required 22 min on average to bring a patient into the room after surgeon identification., Conclusion: The SmartOR automatically and reliably captures data on OR room state and, in real time, identifies outlier cases that may be examined closer to improve efficiency. As no manual entry is required, the data are indisputable and allow OR teams to maintain a patient-centric focus.

Background: Opportunities exist to revise the current residency selection process to capture desirable candidate competencies. We examined the extent to which components of the American College of Surgeons/Association for Surgical Education simulation-based medical student curriculum combined with a teamwork activity could be used as potential screening method., Methods: Students participated in a workshop consisting of training/evaluation of knot tying, suturing, airway management, gowning/gloving, and teamwork. Surveys were given to medical students (MS) and faculty/resident/staff (FRS) to examine their opinions about the residency screening process, the most critical competencies to assess, and the effectiveness of each station for candidate evaluation., Results: Communication (FRS, 4.86 ± .35; MS, 4.93 ± .26), leadership (FRS, 4.41 ± .80; MS, 4.5 ± .76), judgment (FRS, 4.62 ± .74; MS, 4.67 ± .62), professionalism (FRS, 4.64 ± .73; MS, 5.00 ± .00), integrity (FRS, 4.71 ± .78; MS, 4.87 ± .35), and grit/resilience (FRS, 4.71 ± .78; MS, 4.53 ± .74) were considered most valuable for candidate screening. The simulation-based curriculum for evaluation of residency candidates was rated lowest by both groups. Open response comments indicated positive perceptions of this process., Conclusions: Employing simulation to assess candidates may be most beneficial for examining nontechnical attributes. Future work should continue to explore this area., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Introduction: Currently, no prerequisite teaching qualification is required to serve as faculty for SAGES hands-on courses (SAGES-HOC). The Lapco-Train-the-Trainers (Lapco-TT) is a course for surgical trainers, in which delegates learn a standardized teaching technique for skills acquisition. The aims of this study were to 1) determine if this curriculum could be delivered in a day course to SAGES-HOC faculty and 2) assess the impact of such training on learners' educational experience taught by this faculty at a subsequent SAGES-HOC., Methods and Procedures: Six experts attended a one-day Lapco-TT course. SAGES-HOC participants were split into two groups: Group A taught by Lapco-TT trained, and Group B by "untrained" course faculty. Opinion surveys were completed by both the SAGES-HOC learners and the Lapco-TT trained course faculty. Furthermore, the latter underwent self-, learner-, and observer-based evaluation using a previously validated teaching assessment tool (cSTTAR). Mean scores were reported and analyzed [Mann-Whitney U, t test (p < 0.05)]., Results: All 6 Lapco-TT delegates found the course useful (5), and felt that it would influence the way they taught in the OR (4.83), that their course objectives were met (4.83), and that they would recommend the course to their colleagues (4.83). Of the SAGES-HOC participants, compared to Group B (n = 22), Group A learners(n = 10) better understood what they were supposed to learn (5 vs. 4.15 [p = 0.046]) and do (5 vs. 4 [p = 0.046]), felt that the session was well organized (5 vs. 4 [p = 0.046]), that time was used effectively (5 vs. 3.9 [p = 0.046]), and that performance feedback was sufficient (5 vs. 3.9 [p = 0.028]) and effective (5 vs. 3.95 [p = 0.028]). Group A faculty were rated significantly higher by their learners on the cSTTARs than Group B (p < 0.0005). Group A faculty rated themselves significantly lower than both expert observers (p < 0.0005) and compared to the Group B faculty's self-assessment (p < 0.002)., Conclusions: The Lapco-TT course can be delivered effectively over one day and impacts the educational experience of learners at a SAGES-HOC. This could help establish a standardized method of teaching at SAGES-HOCs and thereby increase their value for learners.

Background: To assess the integrity of hernia repair, imaging modalities such as computed tomography or ultrasound (US) are commonly used. Neither modality has currently the capacity to simultaneously image the mesh and quantify a prosthetic and surrounding tissue stiffness. In this pilot study, we hypothesize that US shear wave elastography (SWE) can be used to identify a polyester mesh and a biologic graft and to assess their stiffness noninvasively in a rat model of bridging hernia repair., Methods: Lewis rats underwent hernia creation and repair with Parietex or Strattice at 30 d. After 3 mo, the animals were euthanized, and the Young's Modulus was measured using SWE. Three-dimensional reconstructions of the hernia pre- and post-repair were performed using in-house image processing algorithms., Results: SWE was capable of accurate and real-time assessment and diagnosis of the hernia defects in vivo. Young's Modulus of Parietex meshes and Strattice grafts as estimated from the shear wave elastograms were found to be statistically different from each other (P < 0.05). Accurate three-dimensional reconstructions of the hernia defects pre- and post-repair were generated., Conclusions: In this study, we demonstrate the feasibility of using US SWE to detect ventral hernias and evaluate mesh repair in vivo. Our results indicate that the presence of a hernia and repair can be reliably visualized by SWE and three dimensionally reconstructed. Thus, this technique may provide both structural and functional information regarding the hernia and the repair., (Copyright © 2016 Elsevier Inc. All rights reserved.)

This paper presents a method for localizing the position of a liver and a tumor within the tissue during a minimally invasive liver operation. From pre-operative CT scans, the liver volume and its internal structures are segmented using image-processing techniques. Based on these segmentations, a three-dimensional mechanical model is built to compute the liver volume and internal structure displacement under boundary conditions such as external forces from the surgical instrument. This can help the surgeon understand the motion of internal structures when manipulating the liver. To validate our method, an experiment on a porcine liver explant was performed to assess the difference between actual tissue motion and the mechanical model.

Background: Surgical energy has been widely implemented because of ease of use, effective hemostasis, and surgical dissection. Studies demonstrate its use to be an independent risk factor for postoperative wound infection. Methicillin-resistant Staphylococcus aureus (MRSA) is the most common bacteria found in postoperative mesh infection. No reports are available on the sequelae of surgical energy use for open ventral hernia repair (oVHR) with mesh. We hypothesized that increasing amounts of surgical energy will result in higher infectious burden after oVHR with composite multifilament polyester mesh (Parietex™ PCO)., Methods: New Zealand rabbits underwent bridging oVHR with Parietex™ PCO and were divided into three surgical treatment groups: (1) scalpel alone, (2) 120 J of energy, and (3) 600 J of energy. The bioprosthesis was then inoculated with 10 5 colony-forming units of MRSA. Rabbits were survived for 7 days with daily physical examination. Complete blood count, basci metabolic panel, and blood cultures were performed on postoperative days one, four, and seven. Surviving rabbits were killed, and meshes explanted for MRSA colony counts., Results: Rabbits receiving the most surgical energy developed signs and symptoms of severe sepsis and wound necrosis within 24 h. In comparison, rabbits receiving no surgical energy had significantly less MRSA recovered from explanted mesh, significantly less bacteremia, and fewer adhesions., Conclusions: Increased use of surgical energy promoted greater colonization, exaggerated septic response to bacterial contamination, and more severe adhesions. In the absence of devitalized tissue, rabbits can effectively limit bacterial contamination. These findings support the surgical principles of proper tissue handling and highlight the detrimental effects of indiscriminant surgical energy usage, thus emphasizing the importance of programs such as Fundamental Use of Surgical Energy.

Background: The purpose of this study was to assess the adequacy of current surgical residency and gastroenterology (GI) fellowship flexible endoscopy training as measured by performance on the FES examination., Methods: Fifth-year general surgery residents and GI fellows across six institutions were invited to participate. All general surgery residents had met ACGME/ABS case volume requirements as well as additional institution-specific requirements for endoscopy. All participants completed FES testing at the end of their respective academic year. Procedure volumes were obtained from ACGME case logs. Curricular components for each specialty and institution were recorded., Results: Forty-eight (28 surgery and 20 GI) trainees completed the examination. Average case numbers for residents were 76 ± 26 colonoscopies and 45 ± 12 EGDs. Among GI fellows, PGY4 s (N = 10) reported 99 ± 64 colonoscopies and 147 ± 79 EGDs. PGY5 s (N = 3) reported 462 ± 307 colonoscopies and 411 ± 260 EGDs. PGY6 GI fellows (N = 7) reported 515 ± 111 colonoscopies and 418 ± 146 EGDs. The overall pass rate for all participants was 75 %, with 68 % of residents and 85 % of fellows passing both the cognitive and skills components. For surgery residents, pass rates were 75 % for manual skills and 85.7 % for cognitive. On the skills examination, Task 2 (loop reduction) was associated with the lowest performance. Skills scores correlated with both colonoscopy (r = 0.46, p < 0.001) and EGD experience (r = 0.46, p < 0.001). Receiver operating characteristics curves were examined among the resident cohort. The minimum number of total cases associated with passing the FES skills component was 103. Significant variability existed in curricular components across institutions., Discussion: These data suggest that current flexible endoscopy training may not be sufficient for all trainees to pass the examination. Implementing additional components of the FEC may prove beneficial in achieving more uniform pass rates on the FES examination.

Background: The purpose of this study was to examine the effectiveness of the SAGES flexible endoscopy course in improving fellows' attitudes, confidence, and skills related to implementing endoscopy in practice., Methods: Fellows participated in a 2-day course consisting of case presentations, expert panels, and hands-on laboratory training. Before and after the course, fellows completed a questionnaire assessing demographics, experiences in residency, practice plans, plans to implement flexible endoscopy in practice, and level of confidence performing 15 endoscopic procedures. Half of the fellows were randomly assigned to complete pre- and post-skills testing using a previously validated endoscopic targeting model., Results: Fifty-four fellows (90 %; age 33.5 ± 2.8; 58 % male) completed the pre- and post-questionnaire. All MIS fellowship types were represented. Almost half (48 %) reported none or very little flexible endoscopy in their current fellowship. The average prior case volume among those completing an ACGME-approved residency (42/54) was 76 upper and 75 lower endoscopies with one-third reporting no experience in therapeutic EGD (33 %) or polypectomy (31 %). Intentions to implement flexible endoscopy in practice significantly improved after the course overall (3.72 ± .85-3.92 ± .69, p < 0.05; 1 = never; 5 = very frequently). Prior to the course, 39 % of fellows reported plans to use endoscopy in practice "occasionally" or "rarely." After, this decreased to 28 with 72 % planning to implement "frequently" or "very frequently." Mean levels of confidence performing all 15 endoscopic tasks improved significantly after the course. Skills performance for the 27 fellows improved significantly as well; participants decreased their time to perform the targeting task by 40 % (222.3 ± 119.8-133.0 ± 70.1 s; p < 0.001) and decreased errors by 49 % (2.9 ± 1.7-1.5 ± 1.5; p < 0.001)., Conclusions: These results indicate that the SAGES flexible endoscopy course increases fellow confidence to implement endoscopic techniques, expands the ways in which they plan to include endoscopy in practice, and enhances their endoscopic skills.

Background: Surgeons in training must be able to accurately gauge their own ability and performance to better understand where additional practice is needed and can help inform self-directed learning endeavors. This study had the following 3 goals: (1) to examine the accuracy of residents' assessments of their endoscopic skills, (2) to investigate if accuracy improves over time and practice, and (3) to compare the efficacy of 3 interventions-practice only (PO), self-observation (SO), or expert observation (EO)-on self-assessment accuracy., Methods: Overall, 30 first-year general surgery residents completed a pretest on a colonoscopy simulator, which measured time to completion, time to reach the cecum, efficiency of screening, percentage of mucosal surface area examined, time the patient was in pain, and time with a clear view. Residents assigned to the SO and EO conditions reviewed a video of their own performances (SO) or an expert's performance (EO). Residents in all conditions engaged in practice trials using an abstract endoscopy training exercise. Residents then completed a posttest. Self-assessment was examined by calculating discrepancy scores by subtracting actual measurements from participant judgments., Results: Results indicated that performance for participants in the PO group significantly improved from pretest to posttest for 2 of the 6 metrics and participants in the SO and EO groups improved for 4 metrics. In terms of self-assessment discrepancy scores, only the EO group significantly improved for 2 of the 6 metrics (overall time and screening efficiency)., Discussion: Novice trainees are inaccurate self-assessors of their endoscopic skills before training. Allowing trainees to watch videos of themselves or an expert performing an endoscopic task enhances performance. Participants assigned to PO exhibited decreased ability to accurately judge their own performance. Those in the EO group became significantly better at assessing their overall time and overall efficiency., Summary: Novice trainees are inaccurate self-assessors of their endoscopic skills before training. Allowing trainees to watch videos of themselves or an expert performing an endoscopic task enhances performance., (Copyright © 2016 Association of Program Directors in Surgery.

Background: Provision of optimal postoperative analgesia should facilitate postoperative ambulation and rehabilitation. An optimal multimodal analgesia technique would include the use of nonopioid analgesics, including local/regional analgesic techniques such as surgical site local anesthetic infiltration. This article presents a novel approach to surgical site infiltration techniques for abdominal surgery based upon neuroanatomy., Methods: Literature searches were conducted for studies reporting the neuroanatomical sources of pain after abdominal surgery. Also, studies identified by preceding search were reviewed for relevant publications and manually retrieved., Results: Based on neuroanatomy, an optimal surgical site infiltration technique would consist of systematic, extensive, meticulous administration of local anesthetic into the peritoneum (or preperitoneum), subfascial, and subdermal tissue planes. The volume of local anesthetic would depend on the size of the incision such that 1 to 1.5 mL is injected every 1 to 2 cm of surgical incision per layer. It is best to infiltrate with a 22-gauge, 1.5-inch needle. The needle is inserted approximately 0.5 to 1 cm into the tissue plane, and local anesthetic solution is injected while slowly withdrawing the needle, which should reduce the risk of intravascular injection., Conclusions: Meticulous, systematic, and extensive surgical site local anesthetic infiltration in the various tissue planes including the peritoneal, musculofascial, and subdermal tissues, where pain foci originate, provides excellent postoperative pain relief. This approach should be combined with use of other nonopioid analgesics with opioids reserved for rescue. Further well-designed studies are necessary to assess the analgesic efficacy of the proposed infiltration technique.

Background: Pseudoachalasia is a rare diagnosis manifested by clinical and physiologic symptoms of achalasia, with alternative etiology for outflow obstruction. While malignancy is a frequent cause of pseudoachalasia, prior surgical intervention especially surgery involving the esophagogastric junction, may result in a misdiagnosis of achalasia., Case Presentation: We present a case of a 70 year-old male with dysphagia and weight loss after undergoing a Billroth I and Nissen fundoplication several decades ago. His preoperative studies suggested achalasia and he was therefore referred for an endoscopic myotomy. However, careful interpretation of all the data and intra-operative findings revealed a classic mechanical and functional obstruction requiring takedown of his prior wrap., Conclusions: Individualized interpretation of preoperative studies in the setting of prior foregut surgery is critical to appropriate diagnosis and intervention. This case highlights the significance of endoscopic findings and features of high-resolution manometry specific to pseudoachalasia, which contrasts with classical features of achalasia.

Background: Despite numerous efforts to ensure that surgery residents are adequately trained in the areas of laparoscopy and flexible endoscopy, there remain significant concerns that graduates are not comfortable performing many of these procedures., Methods: Online surveys were sent to surgery residents (98 items, PGY1-5 Categorical) and faculty (78 items, general surgery, and gastrointestinal specialties) at seven institutions. De-identified data were analyzed under an IRB-approved protocol., Results: Ninety-five faculty and 121 residents responded, with response rates of 65 and 52 %, respectively. Seventy-three percent of faculty indicated that competency of their graduating residents were dramatically or slightly worse than previous graduates. Only 29 % of graduating residents felt very comfortable performing advanced laparoscopic (AL) cases and 5 % performing therapeutic endoscopy (TE) cases immediately after graduation. Over half of interns expressed a need for fellowship to feel comfortable performing AL and TE procedures, and this need did not decrease as residents neared graduation. For these procedures, residents receive only "little to some" autonomy, as reported by both faculty and PGY5s. Residents reported that current curricula for laparoscopy and endoscopy consist primarily of clinical experience. Both residents and faculty, though, reported considerable value in other training modalities, including simulations, live animal laboratories, cadavers, and additional didactics., Conclusions: These data indicate that both residents and faculty perceive significant competency gaps for both laparoscopy and flexible endoscopy, with the most notable shortcomings for advanced and therapeutic cases, respectively. Improvement in resident training methods in these areas is warranted.

Background: The fundamentals of endoscopic surgery (FES) examination measures the knowledge and skills required to perform safe flexible endoscopy. A potential limitation of the FES skills test is the size and cost of the simulator on which it was developed (GI Mentor II virtual reality endoscopy simulator; Simbionix LTD, Israel). A more compact and lower-cost alternative (GI Mentor Express) was developed to address this issue. The purpose of this study was to obtain evidence for the validity of scores obtained on the Express platform, so that it can be used for testing., Study Design: General surgery residents at various levels of training and practicing endoscopists at five institutions participated. Each completed the five FES tasks on both simulator platforms in random order, with 3-14 days between tests. Scores were calculated using the same standardized computer-generated algorithm and compared using Pearson's correlation coefficient., Results: There were 58 participants (mean age 32; 76% male) with a broad range of endoscopic experience. The mean (95% confidence interval) FES scores were 72 (67:77) on the GI Mentor II and 66 (60:71) on the Express. The correlation between scores on the two platforms was 0.86 (0.77:0.91; p < 0.0001)., Conclusion: There is a high correlation between FES manual skills scores measured on the original platform and the new Express, providing evidence to support the use of the GI Mentor Express for FES testing.

Purpose: Our group has previously reported the development and validation of FIRST (Fundamental Inanimate Robotic Skills Tasks), a series of 4 inanimate robotic skills tasks. Expanding on the initial validation, we now report face, content and construct validity of FIRST in a large multi-institutional cohort of experts and trainees., Materials and Methods: A total of 96 residents, fellows and attending surgeons completed the FIRST exercises at participating institutions. Participants were classified based on previous robotic experience and task performance was compared across groups to establish construct validity. Face and content validity was assessed from participant ratings of the tasks on a 5-point Likert scale., Results: A total of 51 novice, 22 intermediate and 23 expert participants with a median previous robotic experience of 0 (range 0 to 3), 10 (range 5 to 30) and 200 cases (range 55 to 2,000), respectively (p<0.001), were assessed across all 4 inanimate robotic skills tasks. Expert and intermediate groups reliably outperformed novices (p<0.01). Experts also performed better than intermediates on all exercises (p<0.01). A survey of participants on their perceptions of the tasks yielded excellent face and content validity., Conclusions: We confirm robust face, content and construct validity of 4 inanimate robotic training tasks in a large multi-institutional cohort. FIRST tasks are reliably able to discern among expert, intermediate and novice robotic surgeons. Validation data from this large multi-institutional cohort is useful as we incorporate these tasks into a comprehensive robotic training curriculum., (Copyright © 2015 American Urological Association Education and Research, Inc.

Given the pace of change in surgery today and a growing need to decrease variability in the delivery of health care to optimize quality while minimizing cost, surgeons need an "educational home" where they can return to intermittently through their career to retool. We need as robust of an educational structure to support practicing surgeons as we have for students and postgraduate trainees., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Background: Operating rooms have become increasingly complex environments and more prone to errors because of loss of situation awareness. Adding computer intelligence to the operating room may help overcome these limitations particularly if the system can automatically track which step of an operation a surgeon is performing. To develop such a platform, it is necessary to track which laparoscopic instruments are being used and in which port they are inserted. This article describes the development and validation of a "Smart Trocar" that can automatically perform this function., Methods: A Smart Trocar system prototype was developed that uses a wireless camera attached to a standard laparoscopic port and custom software algorithms. The system recognizes color wheels attached to the handle of a laparoscopic instrument and compares the unique color pattern to an instrument library for proper tool identification. The system was tested for reliability in a box trainer environment using a variety of tool positions and levels of room light illumination., Results: Correct color classification was achieved in 96.7% of trials. There were no errors in detection of the color wheel in space. In addition, the distance of the color wheel from the camera did not influence results and correct classifications were evenly distributed among the 12 laparoscopic tool positions tested., Conclusion: This work describes a Smart Trocar system that identifies which laparoscopic tool is being used and in which port and proves its reliability. The system is an important element of a more comprehensive program being developed to automatically understand what step of an operation a surgeon is performing and use these data to improve situation awareness in the operating room., (© The Author(s) 2014.)
