Background: The COVID-19 pandemic has had a profound impact on surgical training globally. We aimed to explore and identify the specific challenges faced by women surgeons during the pandemic and provide recommendations for improvement.

Methods: A survey was conducted among trainee members of the Association of Women Surgeons, assessing various aspects of clinical training, mental well-being, and personal and professional life.

Background: We previously developed the Pelvic Surgery Difficulty Index for predicting intraoperative events and postoperative outcomes associated with rectal mobilization with or without proctectomy ("deep pelvic dissection"). The aim of this study was to validate the scoring system as a prognostic tool for outcomes of pelvic dissection, regardless of the cause of dissection.

Methods: Consecutive patients who underwent elective deep pelvic dissection at our institution from 2009 to 2016 were reviewed.

Background: In the United States, 37% of all opioids are prescribed in the surgical setting, many of which report initial exposure in the postoperative period.

Objective: This study aimed to assess the impact of a narcotic-sparing enhanced recovery after surgery protocol on postoperative narcotic use by patients and to assess its impact on the narcotic-prescribing practices of physicians.

Design: Data regarding consecutive narcotic-naïve patients who underwent a surgical procedure from January 2013 to August 2017 were retrospectively reviewed.

Background Magnetic resonance imaging (MRI) is currently utilized for the pretreatment staging of locally advanced rectal cancer; however, there is no consensus regarding the utility of repeat MRI for restaging following neoadjuvant chemoradiotherapy (CRT). In this study, we aimed to investigate the clinical utility of restaging MRI after CRT in patients with clinical stage II-III rectal cancer. Methodology We performed a retrospective observational study at a tertiary care hospital.

Lessons Learned: Treatment for patients with metastatic colorectal cancer (mCRC) typically involves multiple lines of therapy with eventual development of treatment resistance. In this single-arm, phase II study involving heavily pretreated patients, the combination of sorafenib and capecitabine yielded a clinically meaningful progression-free survival of 6.2 months with an acceptable toxicity profile.

Background: Residency programs select medical students for interviews and employment using metrics such as the United States Medical Licensing Examination (USMLE) scores, grade-point average (GPA), and class rank/quartile. It is unclear whether these metrics predict performance as an intern. This study tested the hypothesis that performance on these metrics would predict intern performance.

Background: Fellowship program directors have a considerable influence on the future practice patterns of their trainees. Multiple studies have demonstrated that industry can also exert substantial influence on the practice patterns of physicians as a whole. The purpose of this study is to quantify industry support of fellowship program directors across surgical subspecialties and to assess the prevalence of this support within specific subspecialties.

Objective: To assess the efficacy of an intern surgical skills curriculum involving a boot camp for core open and laparoscopic skills, self-guided practice with positive and negative incentives, and semiannual performance evaluations.

Design: Longitudinal cohort study.

Setting: Academic tertiary care center.

Objective: Several aspects of medical training may contribute to the ultimate goal of producing excellent physicians whose patients will have the best possible outcomes. However, the relative importance of education, evaluation and feedback, duty hours, practice structure, and program culture in achieving this goal is unclear. This study assessed associations among in-training exam performance, Accreditation Council for Graduate Medical Education (ACGME) Resident Survey responses, and American Board of Medical Specialties (ABMS) national board exam performance.

Crohn's disease (CD) results from dysregulated immune responses to gut microbiota in genetically susceptible individuals, affecting multiple areas of the gastrointestinal tract. Innate lymphoid cells (ILCs) are tissue-resident innate effector lymphocytes which play crucial roles in mucosal immune defense, tissue repair, and maintenance of homeostasis. The accumulation of IFN--producing ILC1s and increased level of proinflammatory cytokines produced by ILCs has been observed in the inflamed terminal ileum of CD patients.

Background: Although women are increasingly represented in American surgery, data regarding sex and academic rank of the leadership of fellowship programs are lacking.

Methods: Demographics and academic ranks for fellowship program directors were analyzed for 811 surgery fellowship programs across 14 specialties. Associations between academic rank and sex were assessed using a χ independence test.

Rectal prolapse is usually of benign etiology. Rarely, sigmoido-rectal intussusception results from a malignant lead-point. We report the case of a patient with a partially obstructing sigmoid cancer causing a full thickness rectal prolapse requiring surgical intervention.

Background: Despite major advances in the medical management of Crohn's disease (CD), a significant proportion of patients will require surgery within 5 years of diagnosis. Malnutrition is an independent risk factor for adverse post-operative outcomes following gastrointestinal surgery. Data on the value of pre-operative total parenteral nutrition (TPN) in CD patients are mixed and there is a paucity of data in the biologic era.

Background: Objective criteria to predict difficult pelvic dissection with prognostic significance are lacking. Previous studies have focused on predicting intraoperative conversion and not evaluated factors specific to pelvic surgery. We aimed to develop an objective, prognostic, preoperative assessment to predict difficult pelvic dissections and clinical outcomes.

Patients with inflammatory bowel disease (IBD) commonly require surgery despite the availability of an increasingly large repertoire of powerful immunosuppressive medications for the treatment of IBD. Optimizing patients' care preoperatively is crucial to obtaining good surgical outcomes. This review discusses preoperative assessment and management principles including assessing disease location and activity with cross-sectional or endoscopic imaging, addressing modifiable risk factors (i.

Background And Objectives: Patients who undergo colorectal surgery have high postoperative morbidity, with ileostomates being the most disadvantaged. Recent studies assessing readmission risk factors do not provide a specific prediction model and, if so, do not focus on patients who have had colorectal surgery; thus, the results of these studies have limited applicability to our specialized practice. We wanted to develop a prediction model for readmission within 30 days of discharge after ileostomy creation.

Although the effects of biologic agents on postoperative outcomes in Crohn's disease patients have been extensively studied, the effects on intraoperative outcomes, including blood loss, operative time, and length of small bowel resection, remain to be determined. This was a retrospective cohort study at a single tertiary referral center. Crohn's disease (CD) patients who underwent major abdominal surgery were identified.

Cecal volvulus is the rotation of a mobile cecum resulting in a large bowel obstruction. We present the case of a 55-year-old female who underwent a roux-en-y gastric bypass in 2003 and presented to the emergency department with worsening abdominal pain, distention and obstipation. Roentgenogram demonstrated a 14 cm colon suggestive of sigmoid volvulus, but CT scan showed rectal contrast abruptly ending in the distal transverse colon, mesenteric swirling and a distended cecum, consistent with cecal, rather than sigmoid, volvulus.

Objective: This study aimed to evaluate the proportion and characteristics of women who serve in general surgery program director (PD) and associate program director (APD) positions in the United States.

Design: General surgery programs (n = 276) and directors were identified using the Association for Program Directors in Surgery website; information was cross-referenced with American Medical Association FREIDA and Accreditation Council for Graduate Medical Education databases, current to July 1, 2017. Each program's website was accessed to determine the gender and academic ranking of faculty.
