RESUMEN
BACKGROUND: Contemporary perioperative practice seeks to use less intraoperative opioid, diminish postoperative pain and opioid use, and enable less postdischarge opioid prescribing. For inpatient surgery, anesthesia with intraoperative methadone, compared with short-duration opioids, results in less pain, less postoperative opioid use, and greater patient satisfaction. This pilot investigation aimed to determine single-dose intraoperative methadone feasibility for next-day discharge outpatient surgery, determine an optimally analgesic and well-tolerated dose, and explore whether methadone would result in less postoperative opioid use compared with conventional short-duration opioids. METHODS: This double-blind, randomized, dose-escalation feasibility and pilot study in next-day discharge surgery compared intraoperative single-dose IV methadone (0.1 then 0.2, 0.25 and 0.3 mg/kg ideal body weight) versus as-needed short-duration opioid (fentanyl, hydromorphone) controls. Perioperative opioid use, pain, and side effects were assessed before discharge. Patients recorded pain, opioid use, and side effects for 30 days postoperatively using take-home diaries. Primary clinical outcome was in-hospital (intraoperative and postoperative) opioid use. Secondary outcomes were 30-day opioid consumption, pain, opioid side effects, and leftover opioid counts. RESULTS: Median (interquartile range) intraoperative methadone doses were 6 (5 to 7), 11 (10 to 12), 14 (13 to 16), and 18 (15 to 19) mg in 0.1, 0.2, 0.25, and 0.3 mg/kg ideal body weight groups, respectively. Anesthesia with single-dose methadone and propofol or volatile anesthetic was effective. Total in-hospital opioid use (IV milligram morphine equivalents [MME]) was 25 (20 to 37), 20 (13 to 30), 27 (18 to 32), and 25 (20 to 36) mg, respectively, in patients receiving 0.1, 0.2, 0.25 and 0.3 mg/kg methadone, compared to 46 (33 to 59) mg in short-duration opioid controls. Opioid-related side effects were not numerically different. Home pain and opioid use were numerically lower in patients receiving methadone. CONCLUSIONS: The most effective and well-tolerated single intraoperative induction dose of methadone for next-day discharge surgery was 0.25 mg/kg ideal body weight (median, 14 mg). Single-dose intraoperative methadone was analgesic and opioid-sparing in next-day discharge outpatient surgery.

INTRODUCTION: Preoperative differentiation of single-gland (SG) versus multigland (MG) primary hyperparathyroidism (PHPT) can assist with surgical planning, treatment prognostication, and patient counseling. The aim of this study was to identify preoperative predictors of SG-PHPT. METHODS: Retrospective analysis of 408 patients with PHPT who underwent parathyroidectomy at a tertiary referral center. Comprehensive preoperative parameters, including demographic, laboratory, clinical, and imaging results were analyzed. Univariate analysis and binary logistic regression identified preoperative predictors of SG-PHPT. Receiver operator curves were used to analyze the predictive values of existing and novel preoperative predictive models. RESULTS: Elevated parathyroid hormone (PTH) (99.1 pg/mL in SG versus 93.0 pg/mL in MG), elevated calcium (10.8 mg/dL in SG versus 10.6 mg/dL in MG), lower phosphate levels (2.80 mg/dL in SG versus 2.95 mg/dL in MG), and positive imaging (ultrasound 75.6% in SG versus 56.5% in MG; sestamibi 70.8% in SG versus 45.5% in MG) were significantly associated with SG-PHPT. The Washington University Score (a predictive scoring system made from calcium, PTH, phosphate, ultrasound, and sestamibi) and the Washington University Index ([calcium × PTH]/phosphate) were comparable to previous scoring systems used to predict SG versus MG-PHPT. CONCLUSIONS: The association of lower phosphate with SG-PHPT is a novel finding. Previously identified predictors of SG-PHPT, including elevated PTH and positive imaging were confirmed. The Washington University Score and Index are comparable to previously described models and can be used to help surgeons predict if a patient may have SG versus MG-PHPT.

BACKGROUND: The COVID-19 pandemic led the Fellowship Council (FC) to transition rapidly from in-person to virtual interviews. We investigated the impact of this transition on the FC application and main match process. METHODS: Five years (2018-2022) of deidentified FC applicant, program, and match rank data were used to assess differences between in-person (2018-2019) and virtual interview (2021-2022) cycles. Data are expressed as mean ± SD and one-way and two-way MANOVA tests were applied. RESULTS: Trainees applied to an average of 30.4 ± 24.3 programs and ranked an average of 10.7 ± 9.7 programs with a 57% match rate and average rank position of 3.6 ± 3.3. Fellowship programs received an average of 64.9 ± 28.6 applications and ranked an average of 15.4 ± 8.8 applicants with a 95% match rate and average applicant rank position of 3.0 ± 3.4. Applicants who interviewed virtually applied to a greater number of programs (32.7 vs. 27.0; p < 0.001) and ranked a greater number of programs (11.5 vs. 10.0; p = 0.004) with no difference in match rates (58% vs. 55%, p = 0.291). Among matched applicants, there was a significant difference in average rank position (3.20 vs. 4.30, p < 0.001), favoring the in-person cohort. Fellowship programs had more applicants per program (69.2 vs. 57.8; p < 0.001) and ranked more applicants (17.4 vs. 13.3; p < 0.001) during the virtual interview cycles. No difference in either match rates (93% vs. 96%, p = 0.178) or applicant rank position (3.09 vs. 2.93, p = 0.561) was seen between in-person and virtual application cycles. CONCLUSION: Virtual interviews were associated with an increased number of applications for fellowship and applicants ranked by programs but did not impact match rates of either group. Rank match position declined somewhat for applicants but not for fellowship programs. Virtual interviews offer more opportunities for applicants and a greater number of candidates for fellowship programs with only a slight decrement in fellow match rank position.

BACKGROUND: Many surgical adverse events, such as bile duct injuries during laparoscopic cholecystectomy (LC), occur due to errors in visual perception and judgment. Artificial intelligence (AI) can potentially improve the quality and safety of surgery, such as through real-time intraoperative decision support. GoNoGoNet is a novel AI model capable of identifying safe ("Go") and dangerous ("No-Go") zones of dissection on surgical videos of LC. Yet, it is unknown how GoNoGoNet performs in comparison to expert surgeons. This study aims to evaluate the GoNoGoNet's ability to identify Go and No-Go zones compared to an external panel of expert surgeons. METHODS: A panel of high-volume surgeons from the SAGES Safe Cholecystectomy Task Force was recruited to draw free-hand annotations on frames of prospectively collected videos of LC to identify the Go and No-Go zones. Expert consensus on the location of Go and No-Go zones was established using Visual Concordance Test pixel agreement. Identification of Go and No-Go zones by GoNoGoNet was compared to expert-derived consensus using mean F1 Dice Score, and pixel accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). RESULTS: A total of 47 frames from 25 LC videos, procured from 3 countries and 9 surgeons, were annotated simultaneously by an expert panel of 6 surgeons and GoNoGoNet. Mean (± standard deviation) F1 Dice score were 0.58 (0.22) and 0.80 (0.12) for Go and No-Go zones, respectively. Mean (± standard deviation) accuracy, sensitivity, specificity, PPV and NPV for the Go zones were 0.92 (0.05), 0.52 (0.24), 0.97 (0.03), 0.70 (0.21), and 0.94 (0.04) respectively. For No-Go zones, these metrics were 0.92 (0.05), 0.80 (0.17), 0.95 (0.04), 0.84 (0.13) and 0.95 (0.05), respectively. CONCLUSIONS: AI can be used to identify safe and dangerous zones of dissection within the surgical field, with high specificity/PPV for Go zones and high sensitivity/NPV for No-Go zones. Overall, model prediction was better for No-Go zones compared to Go zones. This technology may eventually be used to provide real-time guidance and minimize the risk of adverse events.

BACKGROUND: Despite the advantages of laparoscopic cholecystectomy, major bile duct injury (BDI) rates during this operation remain unacceptably high. In October 2018, SAGES released the Safe Cholecystectomy modules, which define specific strategies to minimize the risk of BDI. This study aims to investigate whether this curriculum can change the knowledge and behaviors of surgeons in practice. METHODS: Practicing surgeons were recruited from the membership of SAGES and the American College of Surgeons Advisory Council for Rural Surgery. All participants completed a baseline assessment (pre-test) that involved interpreting cholangiograms, troubleshooting difficult cases, and managing BDI. Participants' dissection strategies during cholecystectomy were also compared to the strategies of a panel of 15 experts based on accuracy scores using the Think Like a Surgeon validated web-based platform. Participants were then randomized to complete the Safe Cholecystectomy modules (Safe Chole module group) or participate in usually scheduled CME activities (control group). Both groups completed repeat assessments (post-tests) one month after randomization. RESULTS: Overall, 41 participants were eligible for analysis, including 18 Safe Chole module participants and 23 controls. The two groups had no significant differences in pre-test scores. However, at post-test, Safe Chole module participants made significantly fewer errors managing BDI and interpreting cholangiograms. Safe Chole module participants were less likely to convert to an open operation on the post-test than controls when facing challenging dissections. However, Safe Chole module participants displayed a similar incidence of errors when evaluating adequate critical views of safety. CONCLUSIONS: In this randomized-controlled trial, the SAGES Safe Cholecystectomy modules improved surgeons' abilities to interpret cholangiograms and safely manage BDI. Additionally, surgeons who studied the modules were less likely to convert to open during difficult dissections. These data show the power of the Safe Cholecystectomy modules to affect practicing surgeons' behaviors in a measurable and meaningful way.

OBJECTIVE: The Fellowship Council (FC) is transitioning to a competency-based medical education (CBME) model, including the introduction of Entrustable Professional Activities (EPAs) for training and assessment of Fellows. This study describes the implementation process employed by the FC during a ten-month pilot project and presents data regarding feasibility and perceived value. METHODS: The FC coordinated the development of EPAs in collaboration with the sponsoring societies for Advanced GI/MIS, Bariatrics, Foregut, Endoscopy and Hepatopancreaticobiliary (HPB) fellowships encompassing the preoperative, intraoperative, and postoperative phases of care for key competencies. Fifteen accredited fellowship programs participated in this project. The assessments were collected through a unique platform on the FC website. Programs were asked to convene a Clinical Competency Committee (CCC) on a quarterly basis. The pilot group met monthly to support and improve the process. An exit survey evaluated the perceived value of EPAs. RESULTS: The 15 participating programs included 18 fellows and 106 faculty. A total of 655 assessments were initiated with 429 (65%) completed. The average (SD) number of EPAs completed for each fellow was 24(18); range 0-72. Intraoperative EPAs were preferentially completed (71%). The average(SD) time for both the fellow and faculty to complete an EPA was 27(78) hours. Engagement increased from 39% of fellows completing at least one EPA in September to 72% in December and declining to 50% in May. Entrustment level increased from 6% of EPAs evaluated as "Practice Ready" in September to 75% in June. The exit survey was returned by 63% of faculty and 72% of fellows. Overall, 46% of fellows and 74% of program directors recommended full-scale implementation of the EPA framework. CONCLUSION: A competency-based assessment framework was developed by the FC and piloted in several programs. Participation was variable and required ongoing strategies to address barriers. The pilot project has prepared the FC to introduce CBME across all FC training programs.

OBJECTIVE: The aim of this study was to develop and evaluate the performance of artificial intelligence (AI) models that can identify safe and dangerous zones of dissection, and anatomical landmarks during laparoscopic cholecystectomy (LC). SUMMARY BACKGROUND DATA: Many adverse events during surgery occur due to errors in visual perception and judgment leading to misinterpretation of anatomy. Deep learning, a subfield of AI, can potentially be used to provide real-time guidance intraoperatively. METHODS: Deep learning models were developed and trained to identify safe (Go) and dangerous (No-Go) zones of dissection, liver, gallbladder, and hepatocystic triangle during LC. Annotations were performed by 4 high-volume surgeons. AI predictions were evaluated using 10-fold cross-validation against annotations by expert surgeons. Primary outcomes were intersection- over-union (IOU) and F1 score (validated spatial correlation indices), and secondary outcomes were pixel-wise accuracy, sensitivity, specificity, ± standard deviation. RESULTS: AI models were trained on 2627 random frames from 290 LC videos, procured from 37 countries, 136 institutions, and 153 surgeons. Mean IOU, F1 score, accuracy, sensitivity, and specificity for the AI to identify Go zones were 0.53 (±0.24), 0.70 (±0.28), 0.94 (±0.05), 0.69 (±0.20). and 0.94 (±0.03), respectively. For No-Go zones, these metrics were 0.71 (±0.29), 0.83 (±0.31), 0.95 (±0.06), 0.80 (±0.21), and 0.98 (±0.05), respectively. Mean IOU for identification of the liver, gallbladder, and hepatocystic triangle were: 0.86 (±0.12), 0.72 (±0.19), and 0.65 (±0.22), respectively. CONCLUSIONS: AI can be used to identify anatomy within the surgical field. This technology may eventually be used to provide real-time guidance and minimize the risk of adverse events.

BACKGROUND: The interview process represents a necessary but potentially resource intensive process from applicant and program perspectives. This study aimed to identify opinions of the 2020 Fellowship Council (FC) application and match process and in-cycle transition to virtual interviews due to the COVID-19 pandemic. METHODS: Surveys were developed to assess the interview process and were distributed by the FC to all applicants and fellowship programs. Completion was voluntary and data (median [IQR] reported) were anonymous. RESULTS: Applicant response was 53%. Applicants submitted 27.5 (13.25-40) applications, were offered 10 (4-17) interviews, and ranked 10 (5-15) programs. Due to COVID-19, 74% of interview plans changed. Applicants completed 30% of their planned in-person interviews. For decision-making, 90% felt that in-person and 81% virtual interviews were sufficiently informative. Expected cost was $4750 ($2000-$6000) vs. actual cost $1000 ($250-$2250), (p < 0.05). Expected missed work-days were 10 (5-16) versus actual 3 (0-6.25) (p < 0.05). For future interviews, 44% of applicants preferred in-person after virtual pre-interviews, 29% preferred virtual only, and 18% preferred in-person only. Program response was 38%. Programs received 60 (43-85.5) applications, offered 20 (15-26) interviews, completed 16 (12.5-21) interviews, and ranked 14 (10-18) candidates. For decision-making, 92% of programs felt in-person versus 71% virtual interviews were sufficiently informative. Person-hours were greater for in-person 48 (27.5-80) versus virtual 24 (9-40) interviews (p < 0.05). For future interviews, 38% of programs preferred in-person after virtual pre-interviews, 31% preferred in-person only, and 21% preferred virtual only. CONCLUSION: Despite pandemic changes, 81% of applicants and 71% of programs felt they gained sufficient information from virtual sessions to create rank lists. Virtual interviews had lower costs and fewer missed work-days for applicants and decreased resource usage for programs. The majority of both groups preferred either solely virtual or virtual pre-interview followed by in-person interview formats. Virtual interviews should be incorporated into future fellowship application cycles.

BACKGROUND: Gender disparities in surgical leadership have come under increased scrutiny, and in order to better understand why these disparities exist, it is important to study the disparities across surgical fellowship programs. METHODS: Data derived from the Fellowship Council (FC) database for fellows completing training from academic years 2015-2019 were analyzed. Available information included institution, fellowship type, program director (PD), associate program director (APD), faculty, and fellow names for all FC Fellowships. Faculty and fellow gender were determined from personal knowledge or publicly available online biographical information. RESULTS: A total of 1023 fellows and 221 programs were analyzed. The advanced gastrointestinal (GI)/minimally invasive surgery (MIS) fellowship programs included 321 fellows, with a small increase in the percentage of female fellows from 28 to 31% over 5 years. Advanced GI/MIS/bariatric fellowship programs had a total of 262 fellows, also with a small increase in the percent of female fellows, from 29 to 38% in the study period. The gender of program directors, assistant program directors, and faculty for the fellowship programs studied were analyzed as well. Of the 221 programs in the Fellowship Council data, 13.6% of program directors, 18.3% of associate program directors, and 19.9% of faculty were female. Advanced GI/MIS fellowship programs had the lowest percentage of female PDs, with only 9.3% of the program directors being female. Colorectal surgery fellowships had the highest percentage of female PDs, with 33% being female. CONCLUSIONS: In conclusion, women are underrepresented in gastrointestinal surgery fellowships among both trainees and educators. It is likely that a significant contributing factor to this underrepresentation of female fellows is the underrepresentation of female program directors and faculty; although neither our study nor any previously published study has proven that statistically.

BACKGROUND: The COVID-19 pandemic forced surgical fellowship programs to transition from in-person to remote applicant interviews; the virtual interviewing format presented new and unique challenges. We sought to understand applicants' perceived challenges to virtual interviewing for a surgical fellowship program. METHOD: A grounded theory-based qualitative study was performed utilizing semi-structured interviews with fellowship applicants from the 2020 fellowship match. All Fellowship Council-registered applicants were eligible. We purposefully sampled participants to balance across gender, specialty-choice, and academic versus community-program affiliation. Interviews were inductively analyzed by two researchers for prominent themes. RESULTS: Fifteen interviews were conducted. Participants were 60% male (n = 9), with 33% (n = 5) from non-academic institutions. They applied for the following fellowships: Advanced Gastrointestinal/Minimal Invasive (55%), Bariatric (30%), Hepatopancreatobiliary (10%) and Surgical Oncology (5%). Four main themes emerged to describe virtual interview process challenges: (1) perceived data deficiency, (2) superficial personal connections, (3) magnification of non-professionalism, and (4) logistical frustrations. Applicants recommend program directors provide more information about the fellowship prior to interview day and offer informal independent interactions with current and previous fellows. CONCLUSIONS: According to fellowship applicants, virtual interviews resulted in a lack of information for rank-list decision making ultimately requiring them to rely on other information avenues to base their decisions. These applicants have offered advice to fellowship program directors and future applicants to better optimize this process.

OBJECTIVE: To measure surgeon engagement and preferred video duration in a video-based learning program for nerve surgery. BACKGROUND: Educational videos can improve, standardize, and democratize best practices in surgery. To improve care internationally, educators must optimize their videos for learning. However, surgeon engagement and optimal video duration remain undefined. METHODS: A YouTube channel and a video-based learning website, PASSIO Education (passioeducation.com), were examined from 2011 to 2017. We assessed views, geographic location, audience engagement (average percent of video watched), audience retention (percent of viewers at each timepoint), and usage of short (median 7.4, range 4.1-20.3 min) and long (median 17.2, range 6.1-47.7 min) video formats for the same procedures. A survey of PASSIO Education membership examined preferred video duration. RESULTS: Our 117 nerve surgery videos attained over 3 million views with 69% originating outside of the United States. While YouTube achieved more international exposure, PASSIO Education attained a greater mean engagement of 48.4% (14.3% absolute increase, P < 0.0001). Surveyed surgeons (n = 304) preferred longer videos when preparing for infrequent or difficult cases compared with routine cases (P < 0.0001). Engagement declined with video duration, but audience retention between short and long video formats was correlated (τB = 0.52, P < 0.0001). CONCLUSIONS: For effective spread of best practices, we propose the joint use of YouTube for audience outreach and a surgeon-focused platform to maximize educational value. Optimal video duration is surgeon- and case-dependent and can be addressed through offering multiple video durations and interactive viewing options.

BACKGROUND: BDI is the most common serious complication of laparoscopic cholecystectomy. To address this problem, a multi-society consensus conference was held to develop evidenced-based recommendations for safe cholecystectomy and prevention of BDI. METHODS: Literature reviews were conducted for 18 key questions across 6 broad topics around cholecystectomy directed by a steering group and subject experts from 5 surgical societies (Society of Gastrointestinal and Endoscopic Surgeons, Americas Hepato-Pancreato-Biliary Association, International Hepato-Pancreato-Biliary Association, Society for Surgery of the Alimentary Tract, and European Association for Endoscopic Surgery). Evidence-based recommendations were formulated using the grading of recommendations assessment, development, and evaluation methodology. When evidence-based recommendations could not be made, expert opinion was documented. A number of recommendations for future research were also documented. Recommendations were presented at a consensus meeting in October 2018 and were voted on by an international panel of 25 experts with greater than 80% agreement considered consensus. RESULTS: Consensus was reached on 17 of 18 questions by the guideline development group and expert panel with high concordance from audience participation. Most recommendations were conditional due to low certainty of evidence. Strong recommendations were made for (1) use of intraoperative biliary imaging for uncertainty of anatomy or suspicion of biliary injury; and (2) referral of patients with confirmed or suspected BDI to an experienced surgeon/multispecialty hepatobiliary team. CONCLUSIONS: These consensus recommendations should provide guidance to surgeons, training programs, hospitals, and professional societies for strategies that have the potential to reduce BDIs and positively impact patient outcomes. Development of clinical and educational research initiatives based on these recommendations may drive further improvement in the quality of surgical care for patients undergoing cholecystectomy.

INTRODUCTION: Percutaneous cholecystostomy tube (PCT) placement is often the initial management approach to severe acute cholecystitis in the unstable patient. However, the timing of cholecystectomy after PCT has not been carefully examined. The purpose of this study was to compare outcomes of early versus late cholecystectomy following PCT placement. METHODS: The New York SPARCS administrative database was searched for all patients undergoing PCT placement between 2000 and 2012. Patients were followed for subsequent cholecystectomy (CCX) procedures up to 2014. Subsequent cholecystectomies were divided into early (≤ 8 weeks) versus late (> 8 weeks) groups. Outcomes included overall complications, 30-day readmissions, 30-day Emergency Department (ED) visits, and length of stay (LOS). Multivariable regression models were used to examine the differences in clinical outcomes between these two groups, after adjusting for possible confounding factors. RESULTS: There were 9728 patients who underwent PCT placement identified during the time period, as early subsequent cholecystectomy was performed in 1211 patients (40.4%), while 1787 (59.6%) patients had a late cholecystectomy. Average time to cholecystectomy was 38 days in the early group, versus 203 days in the late group. After adjusting for other confounding factors, patients with early CCX had a significantly higher risk of overall complications and longer LOS compared to the late CCX group (P = 0.01 and P = 0.0004, respectively). There were no significant differences in 30-day readmissions and 30-day ED visits. Furthermore, there was no significant difference in the risk of CBD injury between the two groups (n = 21, 1.7% in the early cholecystectomy group and n = 26, 1.5% in the late cholecystectomy group). CONCLUSION: Early cholecystectomy (≤ 8 weeks) is associated with a higher risk of complications and longer hospital LOS compared to cholecystectomy performed at > 8 weeks. Surgeons should be aware and should delay cholecystectomy beyond 8 weeks to improve outcomes.

INTRODUCTION: The timing of cholecystectomy for acute cholecystitis has been debated with most studies favoring early cholecystectomy (< 72 h of onset). However, most reported studies are from single institution studies with only a few population-based studies. The purpose of this study is to compare clinical outcomes of patients undergoing cholecystectomy within 72 h of emergency department (ED) presentation to patients undergoing cholecystectomy following 72 h in a large statewide database. METHODS: The New York SPARCS administrative database was used to identify all adult patients presenting to the ED with a diagnosis of acute cholecystitis from 2005 to 2016. Patients aged < 18, missing data, or other biliary diagnoses were excluded from the analysis. Early cholecystectomy was defined as within 72 h of presentation to the emergency department. Early vs late groups were compared in terms of overall complications, bile duct injury (BDI), hospital length of stay (LOS), 30-days ED visits and readmissions. The linear trends of yearly early/late cholecystectomies were examined using a log-linear Poisson regression models. Multivariable logistic regression model was used to compare complications, BDI, and 30-day readmission/ED visits after controlling for confounding factors. Multivariable generalized linear regression for a negative binomial distributed count data was used to compare LOS. RESULTS: Following the application of the inclusion/exclusion criteria, there were 109,862 patients who presented to an ED with the diagnosis of acute cholecystitis. The majority of patients underwent early cholecystectomy (n = 93,761, 85.3%), whereas only 16,101 patients underwent late cholecystectomy (14.7%). There was an increasing trend of early cholecystectomy from 2005 (81.1%) to 2016 (87.8%). On multivariable regression, patients with early cholecystectomy were less likely to have complications (OR 0.542, 95% CI 0.518-0.566), had shorter LOS (ratio 0.461, 95% CI 0.458-0.465), were less likely to have 30-day readmission (OR 0.871, 95% CI 0.816-0.928), 30-day ED visits (OR 0.909, 95% CI 0.862-0.959), and bile duct injury (OR 0.654, 95% CI 0.444-0.962) compared to late cholecystectomy patients. CONCLUSION: Early cholecystectomy (< 72 h) is associated with fewer complications, specifically BDI, shorter LOS, and fewer 30-day readmissions and ED visits. For patients presenting to the ED for acute cholecystitis, early cholecystectomy should be preferred.

BACKGROUND: The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) has recently developed and announced its Masters Program that aims to address existing needs of practicing surgeons for lifelong learning and consists of eight clinical pathways each containing three anchoring procedures. The objective of this study was to select the seminal articles for each anchoring procedure of these pathways using a systematic methodology. METHODS: A systematic literature search of Web of Science was conducted for the most cited articles for each of the anchoring procedures of the SAGES Masters pathways. The most relevant identified articles were then reviewed by expert members of the relevant SAGES pathway committees and task forces and the seminal articles chosen for each anchoring procedure using expert consensus. RESULTS: 578 highly cited articles were identified by the original search of the literature and the seminal articles were selected for each anchoring procedure after expert review and consensus. Articles address procedural outcomes, disease pathophysiology, and surgical technique and are presented in this paper. CONCLUSIONS: We have identified seminal articles for each anchoring procedure of the SAGES Masters program pathways using a systematic methodology. These articles provide surgeon participants of this program with a great resource to improve their procedure-specific knowledge and may further benefit the larger surgical community by focusing its attention to must-read impactful work that may inform best practices.

BACKGROUND: Bile duct injury (BDI) is the most common serious complication of laparoscopic cholecystectomy. To address this problem, a multi-society consensus conference was held to develop evidenced-based recommendations for safe cholecystectomy and prevention of BDI. METHODS: Literature reviews were conducted for 18 key questions across six broad topics around cholecystectomy directed by a steering group and subject experts from five surgical societies (SAGES, AHPBA IHPBA, SSAT, and EAES). Evidence-based recommendations were formulated using the GRADE methodology. When evidence-based recommendations could not be made, expert opinion was documented. A number of recommendations for future research were also documented. Recommendations were presented at a consensus meeting in October 2018 and were voted on by an international panel of 25 experts with greater than 80% agreement considered consensus. RESULTS: Consensus was reached on 17 of 18 questions by the Guideline Development Group (GDG) and expert panel with high concordance from audience participation. Most recommendations were conditional due to low certainty of evidence. Strong recommendations were made for (1) use of intraoperative biliary imaging for uncertainty of anatomy or suspicion of biliary injury; and (2) referral of patients with confirmed or suspected BDI to an experienced surgeon/multispecialty hepatobiliary team. CONCLUSION: These consensus recommendations should provide guidance to surgeons, training programs, hospitals, and professional societies for strategies that have the potential to reduce BDIs and positively impact patient outcomes. Development of clinical and educational research initiatives based on these recommendations may drive further improvement in the quality of surgical care for patients undergoing cholecystectomy.

BACKGROUND & AIMS: Dysphagia is a consequence of antireflux surgery (ARS) for gastroesophageal reflux disease (GERD). We studied patient management and symptomatic outcomes. METHODS: We performed a retrospective study of 157 consecutive adult patients with GERD (mean age, 65.1 ± 1.0 y; 72% female) who underwent ARS at a tertiary care center from 2003 through 2014. We characterized postfundoplication dysphagia using a self-reported Likert scale, which ranged from a low score of 0 (no dysphagia) to a high score of 4 (severe daily dysphagia); scores of 2 or more indicated clinically significant dysphagia. Postfundoplication dysphagia was categorized as early (≤6 wk after ARS) or late (>6 wk after ARS), and Kaplan-Meier analyses were used to assess the time to development of clinically significant dysphagia. We performed univariate and multivariate analyses to assess management response and identify factors associated with dysphagia. The primary aim was to determine the prevalence and clinical course of postfundoplication dysphagia in patients with GERD treated with ARS. RESULTS: Of the 157 patients, 54.8% had early postfundoplication dysphagia (clinically significant in 20.4%); only 3.5% required endoscopic intervention. Over 2.1 ± 0.2 years of follow-up evaluation, 29 patients (18.5%) developed late postfundoplication dysphagia. Based on Kaplan-Meier analysis, the median time to clinically significant late postfundoplication dysphagia was 0.75 years (95% CI, 0.26-1.22). Of 13 patients (44.8%) who underwent endoscopic dilation, improvement was reported by 92.3%, with a mean decrease in dysphagia severity of 1.55 ± 0.3, based on the Likert scale. Prefundoplication dysphagia, early postfundoplication dysphagia, recurrent hiatal hernia, and lack of contraction reserve following multiple rapid swallows were univariate predictors of late postfundoplication dysphagia (P ≤ .04); lack of contraction reserve was associated independently with late postfundoplication dysphagia, based on multivariate logistic regression analysis (odds ratio, 3.73; 95% CI, 1.11-12.56). CONCLUSIONS: Early and late postfundoplication dysphagia can be successfully managed conservatively or with endoscopic dilation, respectively. Lack of contraction reserve on multiple rapid swallows is associated independently with late postfundoplication dysphagia.

BACKGROUND: Approximately 50 million US patients undergo ambulatory surgery annually. Postoperative opioid overprescribing is problematic, yet many patients report inadequate pain relief. In major inpatient surgery, intraoperative single-dose methadone produces better analgesia and reduces opioid use compared with conventional repeated dosing of short-duration opioids. This investigation tested the hypothesis that in same-day ambulatory surgery, intraoperative methadone, compared with short-duration opioids, reduces opioid consumption and pain, and determined an effective intraoperative induction dose of methadone for same-day ambulatory surgery. METHODS: A double-blind, dose-escalation protocol randomized 60 patients (2:1) to intraoperative single-dose intravenous methadone (initially 0.1 then 0.15 mg/kg ideal body weight) or conventional as-needed dosing of short-duration opioids (eg, fentanyl, hydromorphone; controls). Intraoperative and postoperative opioid consumption, pain, and opioid side effects were assessed before discharge. Patient home diaries recorded pain, opioid use, and opioid side effects daily for 30 days postoperatively. Primary outcome was in-hospital (intraoperative and postoperative) opioid use. Secondary outcomes were 30 days opioid consumption, pain intensity, and opioid side effects. RESULTS: Median (interquartile range) methadone doses were 6 (5-6) and 9 (8-9) mg in the 0.1 and 0.15 mg/kg methadone groups, respectively. Total opioid consumption (morphine equivalents) in the postanesthesia care unit was significantly less compared with controls (9.3 mg, 1.3-11.0) in subjects receiving 0.15 mg/kg methadone (0.1 mg, 0.1-3.3; P < .001) but not 0.1 mg/kg methadone (5.0 mg, 3.3-8.1; P = .60). Dose-escalation ended at 0.15 mg/kg methadone. Total in-hospital nonmethadone opioid use after short-duration opioid, 0.1 mg/kg methadone, and 0.15 mg/kg methadone was 35.3 (25.0-44.0), 7.1 (3.7-10.0), and 3.3 (0.1-5.8) mg morphine equivalents, respectively (P < .001 for both versus control). In-hospital pain scores and side effects were not different between groups. In the 30 days after discharge, patients who received methadone 0.15 mg/kg had less pain at rest (P = .02) and used fewer opioid pills than controls (P < .0001), whereas patients who received 0.1 mg/kg had no difference in pain at rest (P = .69) and opioid use compared to controls (P = .08). CONCLUSIONS: In same-day discharge surgery, this pilot study identified a single intraoperative dose of methadone (0.15 mg/kg ideal body weight), which decreased intraoperative and postoperative opioid requirements and postoperative pain, compared with conventional intermittent short-duration opioids, with similar side effects.

BACKGROUND: Robotic platforms have the potential advantage of providing additional dexterity and precision to surgeons while performing complex laparoscopic tasks, especially for those in training. Few quantitative evaluations of surgical task performance comparing laparoscopic and robotic platforms among surgeons of varying experience levels have been done. We compared measures of quality and efficiency of Fundamentals of Laparoscopic Surgery task performance on these platforms in novices and experienced laparoscopic and robotic surgeons. METHODS: Fourteen novices, 12 expert laparoscopic surgeons (>100 laparoscopic procedures performed, no robotics experience), and five expert robotic surgeons (>25 robotic procedures performed) performed three Fundamentals of Laparoscopic Surgery tasks on both laparoscopic and robotic platforms: peg transfer (PT), pattern cutting (PC), and intracorporeal suturing. All tasks were repeated three times by each subject on each platform in a randomized order. Mean completion times and mean errors per trial (EPT) were calculated for each task on both platforms. Results were compared using Student's t-test (P < 0.05 considered statistically significant). RESULTS: Among novices, greater errors were noted during laparoscopic PC (Lap 2.21 versus Robot 0.88 EPT, P < 0.001). Among expert laparoscopists, greater errors were noted during laparoscopic PT compared with robotic (PT: Lap 0.14 versus Robot 0.00 EPT, P = 0.04). Among expert robotic surgeons, greater errors were noted during laparoscopic PC compared with robotic (Lap 0.80 versus Robot 0.13 EPT, P = 0.02). Among expert laparoscopists, task performance was slower on the robotic platform compared with laparoscopy. In comparisons of expert laparoscopists performing tasks on the laparoscopic platform and expert robotic surgeons performing tasks on the robotic platform, expert robotic surgeons demonstrated fewer errors during the PC task (P = 0.009). CONCLUSIONS: Robotic assistance provided a reduction in errors at all experience levels for some laparoscopic tasks, but no benefit in the speed of task performance. Robotic assistance may provide some benefit in precision of surgical task performance.

BACKGROUND: Bile duct injury (BDI) remains the most dreaded complication following cholecystectomy with serious repercussions for the surgeon, patient and entire healthcare system. In the absence of registries, the true incidence of BDI in the United States remains unknown. We aim to identify the incidence of BDI requiring operative intervention and overall complications after cholecystectomy. METHODS: Utilizing the Truven Marketscan® research database, 554,806 patients who underwent cholecystectomy in calendar years 2011-2014 were identified using ICD-9 procedure and diagnosis codes. The final study population consisted of 319,184 patients with at least 1 year of continuous enrollment and who met inclusion criteria. Patients were tracked for BDI and other complications. Hospital cost information was obtained from 2015 Premier data. RESULTS: Of the 319,184 patients who were included in the study, there were a total of 741 (0.23%) BDI identified requiring operative intervention. The majority of injuries were identified at the time of the index procedure (n = 533, 72.9%), with 102 (13.8%) identified within 30-days of surgery and the remainder (n = 106, 14.3%) between 31 and 365 days. The operative cumulative complication rate within 30 days of surgery was 9.84%. The most common complications occurring at the index procedure were intestinal disorders (1.2%), infectious (1%), and shock (0.8%). The most common complications identified within 30-days of surgery included infection (1.5%), intestinal disorders (0.7%) and systemic inflammatory response syndrome (SIRS) (0.7%) for cumulative rates of infection, intestinal disorders, shock, and SIRS of 2.0, 1.9, 1.0, and 0.8%, respectively. CONCLUSION: BDI rate requiring operative intervention have plateaued and remains at 0.23% despite increased experience with laparoscopy. Moreover, cholecystectomy is associated with a 9.84% 30-day morbidity rate. A clear opportunity is identified to improve the quality and safety of this operation. Continued attention to educational programs and techniques aimed at reducing patient harm and improving surgeon skill are imperative.
