RESUMO
OBJECTIVE: To compare the representation of intersectional (ie, racial/ethnic and gender) identities among surgical faculty versus medical students. BACKGROUND: Health disparities are pervasive in medicine, but diverse physicians may help the medical profession achieve health equity. METHODS: Data from the Association of American Medical Colleges for 140 programs (2011/2012-2019/2020) were analyzed for students and full-time surgical faculty. Underrepresented in medicine (URiM) was defined as Black/African American, American Indian/Alaskan Native, Hispanic/Latino/Spanish Origin, or Native Hawaiian/Other Pacific Islander. Non-White included URiM plus Asian, multiracial, and non-citizen permanent residents. Linear regression was used to estimate the association of year and proportions of URiM and non-White female and male faculty with proportions of URiM and non-White students. RESULTS: Medical students were comprised of more White (25.2% vs 14.4%), non-White (18.8% vs 6.6%), and URiM (9.6% vs 2.8%) women and concomitantly fewer men across all groups versus faculty (all P < 0.01). Although the proportion of White and non-White female faculty increased over time (both P ≤ 0.001), there was no significant change among non-White URiM female faculty, nor among non-White male faculty, regardless of whether they were URiM or not. Having more URiM male faculty was associated with having more non-White female students (estimate = +14.5% students/100% increase in faculty, 95% CI: 1.0% to 8.1%, P = 0.04), and this association was especially pronounced for URiM female students (estimate = +46.6% students/100% increase in faculty, 95% CI: 36.9% to 56.3%, P < 0.001). CONCLUSIONS: URiM faculty representation has not improved despite a positive association between having more URiM male faculty and having more diverse students.

OBJECTIVE: To update and add to the first report commissioned by the Blue Ribbon Committee about 20 years prior. SUMMARY OF BACKGROUND DATA: Following a summit in late 2022 commissioned by the American Board of Surgery regarding competency-based reforms in surgical education and via a partnership with the American College of Surgeons (ACS) and other stakeholders, a Blue Ribbon Committee (BRC-II) on surgical education was formed. The BRC-II would have seven subcommittees. This paper details the work of the Medical Student Subcommittee within the BRC- II. METHODS: The subcommittee's work, supported by staff from the ACS, entailed a thorough literature review, which involved collating and aggregating the findings, identifying key challenges and opportunities, and committing to draft recommendations. These recommendations were then presented and refined via discussions with the Blue Ribbon Committee at large in multiple virtual and in-person settings. RESULTS: The subcommittee's work is detailed below and further summarized in table format. The section below elucidates the medical student education continuum and discusses the pertinent topics of recruitment, surgical engagement in medical student training and the surgical image, training for the current surgical practice model, trainee selection for graduate medical education (GME), and optimizing the transition from undergraduate medical education (UME) to GME. CONCLUSIONS: The last two decades have shown significant changes and shifts in medical education and surgical practice. The findings of BRC-II in this manuscript help to structure the current and future necessary improvements, focusing on different aspects of medical student education.
RESUMO
INTRODUCTION: Laparoscopic cholecystectomy is performed very commonly but laparoscopic common bile duct exploration (LCBDE) is performed infrequently. We aimed to determine the most significant barriers to performing LCBDE and to identify the highest yield interventions to facilitate adoption. METHODS AND PROCEDURES: A national survey was designed by content experts, who regularly perform LCBDE. The survey was distributed by email to the Society of American Gastrointestinal and Endoscopic Surgeons and the American Association for the Surgery of Trauma memberships. Non-U.S. surgeon responses were excluded. Descriptive statistics were used to analyze the results. RESULTS: Seven hundred twenty six practicing surgeons responded to the survey, 543 of which were US surgeons who perform laparoscopic cholecystectomy. Only 27% of respondents preferred to manage choledocholithiasis with LCBDE. Their technique of choice was choledochoscopy (70%). Despite this, 36% of surgeons did not have access to a choledochoscope or were unsure if they did. Seventy percent of surgeons who performed LCBDE did not have supplies readily available in a central stocking location. Only 8.5% of surgeons agreed that routine LCBDE would impact their referral relationship with gastroenterology. About half the respondents (47%) considered LCBDE worth the time, but only 25% knew about reimbursement for the procedure. Almost all (85%) of surgeons understood that LCBDE results in shorter length of stay compared to ERCP. CONCLUSIONS: Only a quarter of the surgeons performing cholecystectomy perform LCBDE. Multiple barriers contribute to low LCBDE utilization. Increasing availability of appropriate equipment, a dedicated supply cart, and teaching fluoroscopic LCBDE interventions may address limitations and increase adoption. These efforts may also increase efficiency, minimizing perceived time and skill restraints. Although many surgeons understand LCBDE decreases length of stay, they are unaware of surgeon-specific LCBDE financial benefits. Systematically addressing these barriers may increase LCBDE adoption, improve patient care, and decrease healthcare costs.
RESUMO
BACKGROUND AND AIMS: Whether glycemic control, as opposed to diabetes status, is associated with the severity of NAFLD is open for study. We aimed to evaluate whether degree of glycemic control in the years preceding liver biopsy predicts the histological severity of NASH. APPROACH AND RESULTS: Using the Duke NAFLD Clinical Database, we examined patients with biopsy-proven NAFLD/NASH (n = 713) and the association of liver injury with glycemic control as measured by hemoglobin A1c (HbA1c). The study cohort was predominantly female (59%) and White (84%) with median (interquartile range) age of 50 (42, 58) years; 49% had diabetes (n = 348). Generalized linear regression models adjusted for age, sex, race, diabetes, body mass index, and hyperlipidemia were used to assess the association between mean HbA1c over the year preceding liver biopsy and severity of histological features of NAFLD/NASH. Histological features were graded and staged according to the NASH Clinical Research Network system. Group-based trajectory analysis was used to examine patients with at least three HbA1c (n = 298) measures over 5 years preceding clinically indicated liver biopsy. Higher mean HbA1c was associated with higher grade of steatosis and ballooned hepatocytes, but not lobular inflammation. Every 1% increase in mean HbA1c was associated with 15% higher odds of increased fibrosis stage (OR, 1.15; 95% CI, 1.01, 1.31). As compared with good glycemic control, moderate control was significantly associated with increased severity of ballooned hepatocytes (OR, 1.74; 95% CI, 1.01, 3.01; P = 0.048) and hepatic fibrosis (HF; OR, 4.59; 95% CI, 2.33, 9.06; P < 0.01). CONCLUSIONS: Glycemic control predicts severity of ballooned hepatocytes and HF in NAFLD/NASH, and thus optimizing glycemic control may be a means of modifying risk of NASH-related fibrosis progression.

OBJECTIVE: To demonstrate the noninferiority of the fundamentals of robotic surgery (FRS) skills curriculum over current training paradigms and identify an ideal training platform. SUMMARY BACKGROUND DATA: There is currently no validated, uniformly accepted curriculum for training in robotic surgery skills. METHODS: Single-blinded parallel-group randomized trial at 12 international American College of Surgeons (ACS) Accredited Education Institutes (AEI). Thirty-three robotic surgery experts and 123 inexperienced surgical trainees were enrolled between April 2015 and November 2016. Benchmarks (proficiency levels) on the 7 FRS Dome tasks were established based on expert performance. Participants were then randomly assigned to 4 training groups: Dome (n = 29), dV-Trainer (n = 30), and DVSS (n = 32) that trained to benchmarks and control (n = 32) that trained using locally available robotic skills curricula. The primary outcome was participant performance after training based on task errors and duration on 5 basic robotic tasks (knot tying, continuous suturing, cutting, dissection, and vessel coagulation) using an avian tissue model (transfer-test). Secondary outcomes included cognitive test scores, GEARS ratings, and robot familiarity checklist scores. RESULTS: All groups demonstrated significant performance improvement after skills training (P < 0.01). Participating residents and fellows performed tasks faster (DOME and DVSS groups) and with fewer errors than controls (DOME group; P < 0.01). Inter-rater reliability was high for the checklist scores (0.82-0.97) but moderate for GEARS ratings (0.40-0.67). CONCLUSIONS: We provide evidence of effectiveness for the FRS curriculum by demonstrating better performance of those trained following FRS compared with controls on a transfer test. We therefore argue for its implementation across training programs before surgeons apply these skills clinically.

BACKGROUND & AIMS: We analyzed markers of fibrosis in serum samples from patients with nonalcoholic fatty liver disease (NAFLD), assessed by liver biopsy. We used serum levels of markers to develop an algorithm to discriminate patients with advanced fibrosis from those with mild or moderate fibrosis and validated its performance in 2 independent cohorts of patients with NAFLD. METHODS: We performed a retrospective analysis of serum samples from 396 patients with NAFLD and different stages of fibrosis (F0-F4), collected from 2007 through 2017 on the day of liver biopsy (training cohort 1). We measured serum concentrations of alpha-2 macroglobulin (A2M), hyaluronic acid (HA), and TIMP metallopeptidase inhibitor 1 (TIMP1), and used measurements to develop an algorithm that could discriminate patients with NAFLD with advanced fibrosis (F3-F4; 24.1% of cohort) from those with mild or moderate fibrosis (F0-F2; 79.5% of cohort). We validated the algorithm using serum samples collected from a separate 396 patients from the same time period and location (validation cohort 1), as well as 244 patients with NAFLD evaluated at a separate location, from 2011 through 2017, within a median of 11 days of liver biopsy (cohort 2). RESULTS: The algorithm identified patients with advanced fibrosis vs mild or moderate fibrosis in training cohort 1 with an area under the receiver operating characteristic (AUROC) curve of 0.867 (95% CI, 0.827-0.907), 84.8% sensitivity (95% CI, 75.5%-91.0%), and 72.3% specificity (95% CI, 66.9%-77.3%), at a cutoff score of 17. The AUROC for the combined validation cohorts 1 and 2 (n=640) was 0.856 (95% CI, 0.820-0.892), identifying patients with 79.7% sensitivity (95% CI, 71.9%-86.2%) and 75.7% specificity (95% CI, 71.8%-79.4%) at the predetermined cutoff score of 17. The algorithm had negative predictive values that ranged from 92.5% to 94.7% in the validation cohorts; it correctly classified 90.0% of F0 samples, 75.0% of F1 samples, 77.4% of F3 samples, and 94.4% of F4 samples. CONCLUSION: We developed an algorithm that identifies patients with advanced fibrosis from those with mild to moderate fibrosis in patients with NAFLD with an AUROC value of approximately 0.86, based on levels of serum biomarkers. We validated the findings in 2 separate sets of patients with biopsy-proven NAFLD. The algorithm can be used non-invasively to determine risk of advanced fibrosis in patients with NAFLD.

BACKGROUND: The biliopancreatic diversion with duodenal switch (BPD/DS) requires operating in three different abdominal quadrants. Previous techniques have used either two docks or a hybrid technique in which the robot is used only to suture the duodeno-ileal anastomosis, while the rest of the operation was performed laparoscopically. Recently, a modification in technique has allowed all operative steps to be completed robotically with a single dock. The operative technique and its technical results are described. METHODS: Operative technique is described. Baseline demographics, operative duration, length of stay, and adverse events (intraoperative, 30-days, and 1-year) of all primary totally robot BPD/DS cases are reported. RESULTS: From Nov. 2011 to Jan. 2014, 59 totally robotic BPD/DS operations were attempted. One was completed hybrid, and the rest were totally robotic. No robotic operation was converted to an open operation. Five trocars were placed, the small bowel was anchored to the anterior abdominal wall, and the robot was docked. Mean age was 44 ± 10 years with a mean preoperative BMI of 56 ± 9 kg/m(2). 69 % was female, and 71 % was Caucasian. Mean operative duration was 306 ± 80 min (60 min less than the hybrid technique). There were no mortality, leaks, venous thromboembolism, or bleeding requiring transfusion. Mean length of stay was 4.6 ± 4.3 days. Three patients were readmitted for nausea and vomiting. There was one superficial wound infection, and three patients needed reoperations in the first year, two for strictures, and one for debriding a suture abscess. CONCLUSIONS: All key technical components of the BPD/DS were performed with low morbidity and mortality with a single dock. Since the surgeon performed all key parts of the operation from the console, the need for experienced bedside assistance was minimized, resulting in shorter operative duration compared to the hybrid technique.

OBJECTIVE: This report describes the development, initial implementation, and reliability of American College of Surgeons Resident Objective Structured Clinical Examination (ACS OSCE). BACKGROUND: Variability in clinical knowledge and skills of entering surgery residents has been demonstrated. The ACS OSCE was developed to evaluate and help remediate residents' knowledge and skills in managing patients with life-threatening conditions. METHODS: A task force of surgeons and professional educators developed 10 standardized clinical case stations, evaluation checklists, and rating scales. Standardized patients (SPs) evaluated each resident's clinical skills (history taking, physical examination, communication, and SP-global scores). Residents completed checklists on diagnosis and management. Coefficient alpha and item-total correlations were used, respectively, to assess internal consistency of metrics and station validity. The resident's overall performance for each station was calculated by combining scores of the individual skills. Analysis of variance compared performance across different institutions. RESULTS: A total of 103 postgraduate year 1 residents from 7 institutions completed the OSCE. Reliability coefficients of skills ranged from 0.38 for diagnosis to 0.68 for global scores. For overall performance on individual stations, the reliability coefficients ranged from 0.51 to 0.82. Using total percent correct scores from highly reliable stations (α > 0.8), wide variability in resident performance was demonstrated within and between the 7 institutions. CONCLUSIONS: The ACS OSCE was successfully implemented across diverse institutions. It had moderate reliability and demonstrated variability among entering surgery residents. The ACS OSCE is now available for broader implementation. It should help reduce resident variability and address the requirements of Accreditation Council for Graduate Medical Education for resident supervision.

INTRODUCTION: The growth of bariatric surgery has resulted in varying types of procedures with increasing complexity. Robotic digital platforms are employed in bariatric surgery to address this increasing complexity in the high-risk obese patient population with difficult anatomy. MATERIALS AND METHODS: This review explores the literature and examines the reported outcomes and complications in using robotics for bariatric surgery. Robotic approaches to adjustable gastric banding, sleeve gastrectomy, gastric bypass, and biliopancreatic diversion with duodenal switch are examined. Revisional cases, learning curves, and cost effectiveness are reviewed, with an eye toward the future of bariatric surgery as the use of robotics is adopted. CONCLUSION: Digital platforms are showing great promise as enabling technology which advance bariatric outcomes. With increasingly complex bariatric cases being performed and revised, the insertion of digital information between the surgeon and the patient leads to better operations for the patient and the surgeon.

BACKGROUND: Impostor syndrome is an internalized sense of incompetence and not belonging. We examined associations between impostor syndrome and holding leadership positions in medicine. STUDY DESIGN: A cross-sectional survey was distributed to US physicians from June 2021 to December 2021 through medical schools and professional organizations. Differences were tested with the chi-square test and t -test for categorical and continuous variables, respectively. Logistic regression was used to identify factors associated with holding leadership positions and experiencing impostor syndrome. RESULTS: A total of 2,183 attending and retired physicians were included in the analytic cohort; 1,471 (67.4%) were in leadership roles and 712 (32.6%) were not. After adjustment, male physicians were more likely than women to hold leadership positions (odds ratio 1.4; 95% CI 1.16 to 1.69; p < 0.001). Non-US citizens (permanent resident or visa holder) were less likely to hold leadership positions than US citizens (odds ratio 0.3; 95% CI 0.16 to 0.55; p < 0.001). Having a leadership position was associated with lower odds of impostor syndrome (odds ratio 0.54; 95% CI 0.43 to 0.68; p < 0.001). Female surgeons were more likely to report impostor syndrome compared to male surgeons (90.0% vs 67.7%; p < 0.001), an association that persisted even when female surgeons held leadership roles. Similar trends were appreciated for female and male nonsurgeons. Impostor syndrome rates did not differ by race and ethnicity, including among those underrepresented in medicine, even after adjustment for gender and leadership role. CONCLUSIONS: Female physicians were more likely to experience impostor syndrome than men, regardless of specialty or leadership role. Although several identity-based gaps persist in leadership, impostor syndrome among racially minoritized groups may not be a significant contributor.

Importance: Surgical department chairs remain conspicuously nondiverse despite the recognized importance of diverse physician workforces. However, the extent of diversity among non-chair leadership remains underexplored. Objective: To evaluate racial, ethnic, and gender diversity of surgical department chairs, vice chairs (VCs), and division chiefs (DCs) in the US. Design, Setting, and Participants: For this cross-sectional study, publicly accessible medical school and affiliated hospital websites in the US and Puerto Rico were searched from January 15 to July 15, 2022, to collect demographic and leadership data about surgical faculty. Two independent reviewers abstracted demographic data, with up to 2 additional reviewers assisting with coding resolution as necessary. In all, 2165 faculty were included in the analyses. Main Outcomes and Measures: Proportions of racial, ethnic, and gender diversity among chairs, VCs, and DCs in general surgery and 5 surgical specialties (neurosurgery, obstetrics and gynecology, ophthalmology, orthopedics, and otolaryngology). Results: A total of 2165 faculty (1815 males [83.8%] and 350 females [16.2%]; 109 [5.0%] African American or Black individuals; 347 [16.0%] Asian individuals; 83 [3.8%] Hispanic, Latino, or individuals of Spanish origin; and 1624 [75.0%] White individuals as well as 2 individuals [0.1%] of other race or ethnicity) at 154 surgical departments affiliated with 146 medical schools in the US and Puerto Rico were included in the analysis. There were more males than females in leadership positions at all levels-chairs (85.9% vs 14.1%), VCs (68.4% vs 31.6%), and DCs (87.1% vs 12.9%)-and only 192 leaders (8.9%) were from racial or ethnic groups that are underrepresented in medicine (URiM). Females occupied more VC than chair or DC positions both overall (31.6% vs 14.1% and 12.9%, respectively) and within racial and ethnic groups (African American or Black females, 4.0% VC vs 1.5% chair and 0.6% DC positions; P < .001). URiM individuals were most commonly VCs of diversity, equity, and inclusion (DEI, 51.6%) or faculty development (17.9%). Vice chairs of faculty development were split equally between males and females, while 64.5% of VCs for DEI were female. All other VCs were predominantly male. Among DC roles, URiM representation was greatest in transplant surgery (13.8%) and lowest in oral and maxillofacial surgery (5.0%). Except for breast and endocrine surgery (63.6% female), females comprised less than 20% of DC roles. Nearly half of DCs (6 of 13 [46.2%]) and VCs (4 of 9 [44.4%]) had no female URiM leaders, and notably, no American Indian, Alaska Native, or Native Hawaiian or Other Pacific Islander individuals were identified in any surgical leadership positions. Conclusions and Relevance: While it is unclear whether promotion from VC to chair or from DC to chair is more likely, these findings of similar gender distribution between chairs and DCs suggest the latter and may partially explain persistent nondiversity among surgical chairs. Female and URiM surgical leaders are disproportionately clustered in roles (eg, VCs of DEI or faculty development) that may not translate into future promotion to department chairs.

OBJECTIVE: Prior studies have focused on the role of the learning environment on students' decisions to pursue surgery, but few have analyzed the impact of the clerkship curriculum. This study assessed surgical clerkship curricula across United States (US) medical schools and their impact on students' likelihood of pursuing a surgical residency. DESIGN: A cross-sectional survey was developed to assess surgery clerkship characteristics. Questions included clerkship duration, number of offered and required surgical services, method of service assignment, and number of advanced clinical electives (e.g., fourth-year sub-internships) and additional surgical clinical opportunities (e.g., surgical elective rotations). Survey results were merged by the Association of American Medical Colleges with the percentages of students who matched into a surgical specialty. Linear regression models estimated the association of covariates with the percentage of students who (1) matched in surgical specialties, (2) were interested in surgery at medical school matriculation and ultimately matched into surgical residency (retention rate), and (3) were not interested in surgery at medical school matriculation but ultimately matched into surgical residency (recruitment rate). SETTING: The survey was distributed to clerkship directors and coordinators at 66 medical schools through the Association for Surgical Education (ASE) from 5/1/2021 to 8/1/2021. PARTICIPANTS: All US medical schools in the ASE. RESULTS: A total of 21 medical schools responded (34.8% response rate). The overall retention rate was 36.4%, and the overall recruitment rate was 25.0%. Clerkships were 4 to 12 weeks. In 81% of programs, students submitted preferences and were assigned services. The percentage of students applying to surgical specialties was not associated with clerkship duration (p=0.79) or the number of required services (p=0.15), subspecialty services offered (p=0.33), or advanced clinical electives (p=0.24) but was associated with a program's having additional surgical clinical opportunities (p=0.02). Most of these factors were not associated with retention or recruitment rates. CONCLUSIONS: Offering more extracurricular surgical clinical opportunities was associated with having more students pursue surgical careers. Though limited by a relatively small sample size, our findings suggest that having shorter clerkships or limited subspecialty offerings may not have a significant influence on students' career choices.

Gastroparesis is a gastric motility disorder characterized by delayed gastric emptying. It is a rare disease and difficult to treat effectively; management is a dilemma for gastroenterologists and surgeons alike. We conducted a systematic review of the literature to evaluate current diagnostic tools as well as treatment options. We describe key elements in the pathophysiology of the disease, in addition to current evidence on treatment alternatives, including nutritional considerations, medical and surgical options, and related outcomes.

OBJECTIVE: To assess the impact of surgeon, patient, and case-specific factors on the learning curve of robot-assisted laparoscopic biliopancreatic diversion with duodenal switch (RA-LBPD/DS). BACKGROUND: The BPD/DS has better resolution of diabetes and hypercholesterolemia, and the best long-term weight loss compared to the laparoscopic gastric band or the Roux-en-Y gastric bypass. Despite excellent results, the BPD/DS is least commonly performed because of greater malabsorption, longer operative duration, and higher technical complication rates. A reduction in technical complications and operative duration will enable the BPD/DS to be offered more frequently. METHODS: Consecutive patients (N = 120) undergoing RA-LBPD/DS between October 2000 and August 2008 were analyzed using univariate and multivariate logistic regression to determine the influence of surgeon and patient factors on complications and operative duration. Independent variables were case number, age, gender, body mass index, American Society of Anesthesiologists (ASA) score, difficult anatomy, and need for extensive adhesiolysis. Dependent variables were complications (leaks, bleeding, and conversion) and operative duration. The best-fit model predicted the risk factors for complications, and a risk-adjusted cumulative sum analysis estimated the learning curve. RESULTS: : Operative duration decreased an average of 3 minutes with each successive case (P < 0.001, R² = 0.63) and with patient's female gender. Adhesiolysis, difficult anatomy, liver biopsy, and higher ASA score increased operative duration. The incidence of high blood loss (13.3%), conversion (2.2%), and leaks (5.8%) were experienced by a total of 22 patients (18.3%). There was no mortality. Complications declined after 50 cases and were strongly predicted by increasing surgeon case number. CONCLUSIONS: The learning curve for the RA-LBPD/DS is 50 cases. Risk factors influencing outcomes were identified.

BACKGROUND: This study assessed the national impact of the COVID-19 pandemic on the education of medical students assigned to surgery clerkship rotations, as reported by surgery clerkship directors(CDs). STUDY DESIGN: In the spring of 2020 and 2021, the authors surveyed 164 CDs from 144 LCME-accredited US medical schools regarding their views of the pandemic's impact on the surgery clerkship curriculum, students' experiences, outcomes, and institutional responses. RESULTS: Overall survey response rates, calculated as no. respondents/no. surveyed were 44.5%(73/164) and 50.6%(83/164) for the spring 2020 and 2021 surveys, respectively. Nearly all CDs(>95%) pivoted to virtual platforms and solutions. Most returned to some form of in-person learning by winter 2020, and pre-pandemic status by spring 2021(46%, 38/83). Students' progression to the next year was delayed by 12%(9/73), and preparation was negatively impacted by 45%(37/83). Despite these data, CDs perceived students' interest in surgical careers was not significantly affected(89% vs. 77.0%, p=0.09). Over the one-year study, the proportion of CDs reporting a severe negative impact on the curriculum dropped significantly(p<0.0001) for most parameters assessed except summative evaluations(40.3% vs. 45.7%,p=0.53). CDs(n=83) also noted the pandemic's positive impact with respect to virtual patient encounters(21.7%), didactics(16.9%), student test performance(16.9%), continuous personal learning(14.5%), engagement in the clerkship(9.6%) and student interest in surgery as a career(7.2%). CONCLUSION: During the pandemic, the severe negative impact on student educational programs lessened and novel virtual curricular solutions emerged. Student interest in surgery as a career was sustained. Measures of student competency and effectiveness of new curriculum, including telehealth, remain areas for future investigation.
RESUMO
OBJECTIVE: The objective assessment of technical skills of junior residents is essential in implementing competency-based training and providing specific feedback regarding areas for improvement. An innovative assessment that can be easily implemented by training programs nationwide has been developed by expert surgeon educators under the aegis of the American College of Surgeons (ACS) Division of Education. This assessment, ACS Objective Assessment of Skills in Surgery (ACS OASIS) uses eight stations to address technical skills important for junior residents within the domains of laparoscopic appendectomy, excision of lipoma, central line placement, laparoscopic cholecystectomy, trocar placement, exploratory laparotomy, repair of enterotomy, and tube thoracostomy. The purpose of this study was to implement ACS OASIS at a number of sites to study its psychometric rigor. DESIGN: The ACS OASIS was pre-piloted at two programs to establish feasibility and to gather information regarding implementation. Each skills station was 12 minutes long, and the faculty completed a checklist with 5 to 15 items, and a global assessment scale. The study was then repeated at three pilot sites and included 29 junior residents who were assessed by a total of 44 faculty. Psychometric data for the stations and checklists were collected and analyzed. SETTING: The pre-pilot sites were Geisinger and University of Tennessee Knoxville.Data were gathered from pilot sites that included Wellspan Health, Duke University, and University of California Los Angeles. RESULTS: The mean checklist score for all learners was 76% (IQR of 66%-85%). The average global rating was 3.36 on a 5-point scale with a standard deviation of 0.56. The overall cut score derived using the borderline group method was at 68% with 34% of performances requiring remediation. Using this criterion, the average number of stations that were completed by each learner without need for remediation was five.The station discrimination index ranged from 0.27 to 0.65 (all above the threshold of 0.25), demonstrating solid psychometric characteristics at the station level. The internal-consistency reliability was 0.76 with SEM of 5.8%. The inter-rater reliability (intraclass correlation) was high at 0.73 with general agreement of 79% between the two raters. The station discrimination was at 0.45 (range of 0.27 to 0.65) indicating a high level of differentiation between high and low performers. Using the generalizability theory, the G-coefficient reliability was at 0.72 with the reliability projection flattening after 8 stations. Overall, 75% to 82% the faculty and learners rated ACS OASIS as realistic and beneficial. CONCLUSIONS: ACS OASIS is a psychometrically sound technical skills assessment tool that can provide useful information for feedback to junior residents and support efforts to remediate gaps in performance.

INTRODUCTION: Repair of large paraesophageal hernias by itself is associated with high failure rates in the morbidly obese. A surgical approach addressing both giant paraesophageal hernia and morbid obesity has, to our knowledge, not been explored in the surgical literature. METHODS: A retrospective review of a bariatric surgery database identified patients who underwent simultaneous repair of large type 3 paraesophageal hernias with primary crus closure and Roux-en-Y gastric bypass (RYGB). Operative time, intraoperative and 30-day morbidity, weight loss, resolution of comorbid conditions and use of antireflux medication were outcome measures. Integrity of crural closure was studied with a barium swallow. RESULTS: Three patients with a mean body mass index of 46kg/m(2) and mean age of 46 years underwent repair of a large paraesophageal hernia, primary crus closure, and RYGB. Mean operative time was 241 minutes and length of stay was 4 days. There was no intraoperative or 30-day morbidity. One patient required endoscopic balloon dilatation of the gastrojejunostomy. At 12 months, all patients were asymptomatic with excellent weight loss and resolution of comorbidities. Contrast studies showed no recurrence of the hiatal hernia. CONCLUSION: Simultaneous laparoscopic repair of large paraesophageal hernias in the morbidly obese is safe and effective.

BACKGROUND: Dehydration treatments (DT) provide intravenous fluids to patients in the outpatient setting; however, the utilization of DT is not well-described. We characterize the cohort receiving DT, the first year it was recorded in a bariatric-specific database. SETTING: A retrospective cohort analysis of patients undergoing bariatric surgery between January 1, 2016, and December 31, 2016, in 791 centers in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program data file. METHODS: Patients ≥ 18 years with a body mass index (BMI) ≥ 35 kg/m2 who underwent laparoscopic adjustable gastric band (LAGB), sleeve gastrectomy (LSG), Roux-en-Y gastric bypass (LRYGB), and biliopancreatic diversion with duodenal switch (LBPD/DS) were identified. Unadjusted and adjusted rates of DT were analyzed. In addition, adjusted rates and indication for readmission were reviewed. RESULTS: The overall rate of dehydration treatments was 3.5% for the 141,748 bariatric surgery cases identified. Patient comorbidities of gastroesophageal reflux (GERD) (odds ratio (OR) 1.49; 95% CI, 1.40-1.59), insulin-dependent diabetes (OR = 1.19; 95% CI, 1.07-1.33), and LRYGB (OR = 1.45; 95% CI, 1.36-1.54) were associated with higher odds of DT. DT only had the highest odds of readmission (OR = 6.22; 95% CI, 5.55-6.98) compared to other outpatient visits. Nausea and vomiting, or fluid, electrolyte, or nutritional depletion was the most common indication for readmission in all groups. CONCLUSIONS: Patients with GERD utilized dehydration treatments after bariatric surgery. DT was highly associated with readmissions, and a better understanding of the clinical application of DT will allow bariatric centers to develop programs to further optimize outpatient treatments.
