Surgical clerkship or medical clerkship first: Does it make a difference?
INTRODUCTION: This study compares NBME surgical clerkship scores of students who completed their medicine clerkship before their surgical clerkship with the performance of those who had not previously completed their medical clerkship. METHODS: The study included 815 New York University School of Medicine students from the years 2014-2018 (571 students took medicine first, while 244 took surgery first). Performance on the surgical clerkship was assessed using the NBME SHELF examination. Statistical comparisons were performed via 2-tailed, independent-samples, unequal-variance t-tests. RESULTS: Mean NBME surgical SHELF scores of the students who had previously taken medicine were significantly higher than students who had not (mean 78.6 vs. 73.5, p < 0.001). Students who had solely medicine (as their first clerkship) before surgery also performed significantly better (mean 78.8 vs. 73.5, p < 0.001). Students who completed surgery later in the year did not perform better on the surgical SHELF, so long as both surgical clerkship cohorts had completed medicine. CONCLUSION: Students who completed their core medical clerkship prior to their surgical clerkship scored significantly better on the NBME surgical SHELF examination.

Predictors and Prognostic Implications of Perioperative Chemotherapy Completion in Gastric Cancer
BACKGROUND: Perioperative chemotherapy in gastric cancer is increasingly used since the "MAGIC" trial, while clinical practice data outside of trials remain limited. We sought to evaluate the predictors and prognostic implications of perioperative chemotherapy completion in patients undergoing curative-intent gastrectomy across multiple US institutions. METHODS: Patients who underwent curative-intent resection of gastric adenocarcinoma between 2000 and 2012 in eight institutions of the US Gastric Cancer Collaborative were identified. Patients who received preoperative chemotherapy were included, while those who died within 90 days or with unknown adjuvant chemotherapy status were excluded. Predictors of chemotherapy completion and survival were identified using multivariable logistic regression and Cox proportional hazards. RESULTS: One hundred sixty three patients were included (median age 63.3, 36.8% female). The postoperative component of perioperative chemotherapy was administered in 112 (68.7%) patients. Factors independently associated with receipt of adjuvant chemotherapy were younger age (odds ratio (OR) 2.73, P = 0.03), T3 tumors (OR 14.3, P = 0.04), lymph node metastasis (OR 5.82, P = 0.03), and D2 lymphadenectomy (OR 4.12, P = 0.007), and, inversely, postoperative complications (OR 0.25, P = 0.008). Median overall survival (OS) was 25.1 months and 5-year OS was 36.5%. Predictors of OS were preexisting cardiac disease (hazard ratio (HR) 2.7, 95% CI 1.13-6.46), concurrent splenectomy (HR 4.11, 95% CI 1.68-10.0), tumor stage (reference stage I; stage II HR 2.62; 95% CI 0.99-6.94; stage III HR 4.86, 95% CI 1.81-13.02), and D2 lymphadenectomy (HR 0.43, 95% CI 0.19-0.95). After accounting for these factors, adjuvant chemotherapy administration was associated with improved OS (HR 0.33, 95% CI 0.14-0.82). CONCLUSION: Completion of perioperative chemotherapy was successful in two thirds of patients with gastric cancer and was independently associated with improved survival.

Factor VIII elevation may contribute to portomesenteric vein thrombosis after laparoscopic sleeve gastrectomy: a multicenter review of 40 patients
BACKGROUND: Portomesenteric vein thrombosis (PMVT) has been increasingly reported after laparoscopic sleeve gastrectomy (LSG). Factor VIII (FVIII) is a plasma sialoglycoprotein that plays an essential role in hemostasis. There is increasing evidence that FVIII elevation constitutes a clinically important risk factor for venous thrombosis. OBJECTIVES: To report the prevalence of FVIII elevation as well as other clinical characteristics in a multicenter series of patients who developed PMVT after LSG. SETTING: University hospitals. METHODS: A retrospective review was conducted of all patients that developed PMVT after laparoscopic bariatric surgery from 2006 to 2016 at 6 high-volume bariatric surgery centers. RESULTS: Forty patients who developed PMVT postoperatively, all after LSG, were identified. During this timeframe, 25,569 laparoscopic bariatric surgery cases were performed, including 9749 LSG (PMVT incidence after LSG = .4%). Mean age and body mass index were 40 years (18-65) and 43.4 kg/m2 (35-59.7), respectively. Abdominal pain was the most common (98%) presenting symptom. Of patients, 92% had a hematologic abnormality identified, and of these, FVIII elevation was the most common (76%). The vast majority (90%) was successfully managed with therapeutic anticoagulation alone. A smaller number of patients required small bowel resection (n = 2) and surgical thrombectomy (n = 1). There were no mortalities. CONCLUSIONS: A high index of clinical suspicion and prompt diagnosis/treatment of PMVT usually leads to favorable outcomes. FVIII elevation was the most common (76%) hematologic abnormality identified in this patient cohort. Further studies are needed to determine the prevalence of FVIII elevation in patients seeking bariatric surgery.

Minimally Invasive Management of Ectopic Pancreas
BACKGROUND: The management of ectopic pancreas is not well defined. This study aims to determine the prevalence of symptomatic ectopic pancreas and identify those who may benefit from treatment, with a particular focus on robotically assisted surgical management. METHODS: Our institutional pathology database was queried to identify a cohort of ectopic pancreas specimens. Additional clinical data regarding clinical symptomatology, diagnostic studies, and treatment were obtained through chart review. RESULTS: Nineteen cases of ectopic pancreas were found incidentally during surgery for another condition or found incidentally in a pathologic specimen (65.5%). Eleven patients (37.9%) reported prior symptoms, notably abdominal pain and/or gastrointestinal bleeding. The most common locations for ectopic pancreas were the duodenum and small bowel (31% and 27.6%, respectively). Three out of 29 cases (10.3%) had no symptoms, but had evidence of preneoplastic changes on pathology, while one harbored pancreatic cancer. Over the years, treatment of ectopic pancreas has shifted from open to laparoscopic and more recently to robotic surgery. CONCLUSIONS: Our experience is in line with existing evidence supporting surgical treatment of symptomatic or complicated ectopic pancreas. In the current era, minimally invasive and robotic surgery can be used safely and successfully for treatment of ectopic pancreas.

Outcomes of patients undergoing curative intent resection for gastric adenocarcinoma: Is there a prognostic difference between tertiary referral public and private hospitals? [Meeting Abstract]
Objective: We sought to assess our experience between a private (TH) and a public hospital (BH), both staffed by faculty and trainees of the same major university medical center. Methods: Our gastric cancer database was used to identify patients undergoing curative intent resection. Descriptive statistics were used to compare demographic data. Kaplan-Meier survival analysis was used to examine recurrence (RFS) and overall survival (OS). Multivariate proportional hazards regression was used to identify factors associated with RFS and OS. Data were risk - and disease stage-stratified. Results: There were 100 patients in the BH group and 242 in the TH group, with a median age 55 and 70.5 years respectively (p<0.001). The majority of BH patients were Asians (60, 60%), and Caucasians (172, 72.3%) in the TH group. The median number of days from diagnosis to surgical intervention at BH was 47.5 vs. 30 days in the TH (p=0.01). BH group had a smaller BMI and more frequently received distal or subtotal gastrectomy. Perioperative morbidity and mortality was equally distributed, as was 30-day readmission rate. Pathologic staging was similarly distributed. By multivariate analysis, hospital of treatment was not associated with RFS (p=0.48) nor OS (p=0.56). Conclusions: Patients receiving care for gastric cancer at major public hospitals have equally good clinical outcomes when compared to patients treated at private hospitals, if cared for by physicians within the same institution dedicated to disease specific entities. Overall survival by treatment hospital

Midclerkship feedback in the surgical clerkship: the "Professionalism, Reporting, Interpreting, Managing, Educating, and Procedural Skills" application utilizing learner self-assessment
BACKGROUND: The Liaison Committee on Medical Education requires midclerkship formative (low stakes) feedback to students regarding their clinical skills. Student self-assessment is not commonly incorporated into this evaluation. We sought to determine the feasibility of collecting and comparing student self-assessment with that of their preceptors using an iPad application. These student self-ratings and preceptor ratings are jointly created and reviewed as part of a face-to-face midclerkship feedback session. METHODS: Using our iPad application for Professionalism, Reporting, Interpreting, Managing, Educating, and Procedural Skills ("PRIMES"), students answer 6 questions based on their self-assessment of performance at midclerkship. Each skill is rated on a 3-point scale (beginning, competent, and strong) with specific behavioral anchors. The faculty preceptors then complete the same PRIMES form during the face-to-face meeting. The application displays a comparison of the 2 sets of ratings, facilitating a discussion to determine individualized learning objectives for the second half of the clerkship. RESULTS: A total of 209 student-preceptor pairs completed PRIMES ratings. On average, student-preceptor ratings were in agreement for 38% of the time. Agreement between students and preceptors was highest for Professionalism (70%) and lowest for Procedural Skills (22%). On average, 60% of student-preceptor ratings did not agree. Students rated themselves lower than preceptors 52% of the time, while only 8% of students rated themselves higher than their preceptors' ratings (this difference is significant at the P value <.05 level). CONCLUSIONS: This study demonstrates the value of using the PRIMES framework to incorporate surgery clerkship students' self-assessment into formative face-to-face midclerkship feedback sessions with their preceptors with the goal to improve performance during the second half of the clerkship.

Urban Bicyclist Trauma: Characterizing the Injuries, Consequent Surgeries, and Essential Sub-Specialties Providing Care
In the United States in 2013, nearly 500,000 bicyclists were injured and required emergency department care. The objectives of this study were to describe the types of injuries which urban bicyclists sustain, to analyze the number and type of surgeries required, and to better delineate the services providing care. This is an observational study of injured bicyclists presenting to a Level I trauma center between February 2012 and August 2014. Most data were collected within 24 hours of injury and included demographics, narrative description of the incident, results of initial imaging studies, Injury Severity Score, admission status, length of stay, surgical procedure, and admitting and discharging service. A total of 706 injured bicyclists were included in the study, and 187 bicyclists (26.4%) required hospital admission. Of those admitted, 69 (36.8%) required surgery. There was no difference in gender between those who required surgery and those who did not (P = 0.781). Those who required surgery were older (mean age 39.1 vs 34.1, P = 0.003). Patients requiring surgery had higher Abbreviated Injury Scores for head (P

Professionalism Training For Surgical Residents: Documenting the Advantages of a Professionalism Curriculum
OBJECTIVES: Professionalism education is a vital component of surgical training. This research attempts to determine whether an annual, year-long professionalism curriculum in a large surgical residency can effectively change professionalism attitudes. SUMMARY OF BACKGROUND DATA: The ACGME mandated 6 competencies in 2003. The competencies of Professionalism and Interpersonal/Professional Communication Skills had never been formally addressed in surgical resident education in the past. METHODS: A professionalism curriculum was developed focusing on specific resident professionalism challenges: admitting mistakes, effective communication with colleagues at all levels, delivering the news of an unexpected death, interdisciplinary challenges of working as a team, the cultural challenge of obtaining informed consent through an interpreter, and the stress of surgical practice on you and your family. These professionalism skills were then evaluated with a 6-station Objective Structured Clinical Examination (OSCE). Identical OSCE scenarios were administered to 2 cohorts of surgical residents: in 2007 (before instituting the professionalism curriculum in 2008) and again in 2014. Surgical residents were rated by trained Standardized Patients according to a behaviorally anchored professionalism criteria checklist. RESULTS: An analysis of variance was conducted of overall OSCE professionalism scores (% well done) as the dependent variable for the 2 resident cohorts (2007 vs 2014). The 2007 residents received a mean score of 38% of professionalism items "well done" (SD 9%) and the 2014 residents received a mean 59% "well done" (SD 8%). This difference is significant (F = 49.01, P < .001). CONCLUSIONS: Professionalism education has improved surgical resident understanding, awareness, and practice of professionalism in a statistically significant manner from 2007 to 2014. This documented improvement in OSCE performance reflects the value of a professionalism curriculum in the care of the patients we seek to serve.
