Abstract Background Microscopic colitis (MC) is suspected to result from increased immune activity in gut mucosa. Immune checkpoint inhibitors (ICIs) treat cancer by activating the immune system, and further investigation is needed regarding their role in the development of MC. Methods A retrospective case series investigated cases of endoscopically and histologically confirmed MC developing after administration of ICIs. Clinical notes and medication administration records were reviewed for demographics, symptom duration, and treatment response. Results Nineteen cases of de novo MC were identified, with 95% of cases requiring steroid treatment, 53% presenting with hospitalization, and colitis-related mortality in 1 individual. Symptom onset occurred a median of 160 days after initiation of ICI therapy and 53 days after their most recent dose of therapy. Patients had a median of 125 days of symptoms, and ICI therapy was held in 70% of individuals due for treatment. Conclusions MC can develop after ICI administration, and presents with severe symptoms, often requiring hospitalization and steroid treatment. In certain individuals this can require a prolonged treatment course of steroid therapy or immunomodulators. Individuals developing diarrhea after ICI therapy warrant thorough workup including endoscopy and rapid treatment initiation given the disease severity observed in this series.
Defining normal pouch function in patients with ileal pouch‐anal anastomosis: a pilot study
SummaryBackgroundMost patients experience good functional outcomes following ileal pouch‐anal anastomosis (IPAA) for ulcerative colitis.AimWe aimed to determine if asymptomatic patients with an IPAA had findings consistent with normal defecation on standard objective anorectal tests.MethodsPatients 18–65 years old with IPAA and self‐reported healthy pouch function were recruited. Patients with chronic pouchitis, Crohn’s disease, anastomotic stricture, or indication for IPAA other than ulcerative or indeterminate colitis were excluded. Patients underwent an interview with an abbreviated Rome Questionnaire followed by high‐resolution ano‐pouch manometry, balloon expulsion test, pouch barostat, and magnetic resonance (MR) defecography.ResultsTwenty patients completed all testing. Six patients were excluded from the final analysis due to symptoms suggestive of pouch evacuation disorder on the abbreviated Rome Questionnaire (n = 2), structural abnormality on MR imaging (n = 3), or both (n = 1). Of the remaining 14 patients, mean anal resting pressure during high‐resolution manometry was 72 ± 16 mmHg, mean anal squeeze pressure was 247 ± 69 mmHg, and mean pouch‐anal gradient during the simulated evacuation was −27 ± 37 mmHg. The meantime to balloon expulsion was 54 seconds. During dynamic MR defecography, the mean descent of ano‐pouch junction was 2.6 cm, and mean pouch evacuation was 44.5% and 74.2% pre‐ and posttoilet phase, respectively.ConclusionsA substantial proportion of patients with IPAA and self‐reported healthy pouch function have anatomic and/or functional abnormalities of the pouch. In asymptomatic IPAA patients with an anatomically normal pouch, we have proposed normal parameters for high‐resolution ano‐pouch manometry, time to balloon expulsion, pouch barostat, and MR defecography.
Emergent and Urgent Surgery for Ulcerative Colitis in the United States in the Minimally Invasive and Biologic Era
BACKGROUND: Although the overall adoption of minimally invasive surgery in the nonemergent management of ulcerative colitis is established, little is known about its utilization in emergency settings. OBJECTIVE: The goal of this study was to assess rates of urgent and emergent surgery over time in the era of emerging biologic therapies and to highlight the current practice in the United States regarding the utilization of minimally invasive surgery for urgent and emergent indications for ulcerative colitis. DESIGN: This was a retrospective analysis study. SETTINGS: Data were collected from the American College of Surgeons National Quality Improvement Program database. PATIENTS: All adult patients who underwent emergent or urgent colectomy for ulcerative colitis were included. MAIN OUTCOME MEASURES: Rates of emergency operations over time and utilization trends of minimally invasive surgery in urgent and emergent settings were assessed. Unadjusted and adjusted overall, surgical, and medical 30-day complication rates were compared between open and minimally invasive surgery. RESULTS: A total of 2219 patients were identified. Of those, 1515 patients (68.3%) underwent surgery in an urgent setting and 704 (31.7%) as an emergency. Emergent cases decreased over time (21% in 2006 to 8% in 2018; p < 0.0001). However, the rate of urgent surgeries has not significantly changed (42% in 2011 to 46% in 2018; p = 0.44). Minimally invasive surgery was offered to 70% of patients in the urgent group (1058/1515) and 22.6% of emergent indications (159/704). Overall, minimally invasive surgery was increasingly utilized over the study period in urgent (38% in 2011 to 71% in 2018; p < 0.0001) and emergent (0% in 2005 to 42% in 2018; p < 0.0001) groups. Compared to minimally invasive surgery, open surgery was associated with a higher risk of surgical, septic, and overall complications, and prolonged hospitalization. LIMITATIONS: This study was limited by its retrospective nature of the analysis. CONCLUSION: Based on a nationwide analysis from the United States, minimally invasive surgery has been increasingly and safely implemented for emergent and urgent indications for ulcerative colitis. Although the sum of emergent and urgent cases remained the same over the study period, emergency cases decreased significantly over the study period, which may be related to improved medical treatment options and a collaborative, specialized team approach.

CIRUGÍA DE URGENCIA Y EMERGENCIA PARA LA COLITIS ULCEROSA EN LOS ESTADOS UNIDOS EN LA ERA MÍNIMAMENTE INVASIVA Y DE TERAPIA BIOLÓGICA ANTECEDENTES: Si bien se ha establecido la adopción generalizada de la cirugía mínimamente invasiva en el tratamiento electivo de la colitis ulcerosa, se sabe poco sobre su utilización en situaciones de emergencia. OBJETIVO: Evaluar las tasas de cirugía de urgencia a lo largo del tiempo en la era de las terapias biológicas emergentes y destacar la práctica actual en los Estados Unidos con respecto a la utilización de la cirugía mínimamente invasiva para las indicaciones de urgencia y emergencia de la colitis ulcerosa. DISEÑO: Análisis retrospectivo. AJUSTES: Base de datos del Programa Nacional de Mejoramiento de la Calidad del Colegio Americano de Cirujanos. PACIENTES: Todos los pacientes adultos que se sometieron a colectomía de emergencia o urgencia por colitis ulcerosa. MEDIDAS DE RESULTADO: Se evaluaron las tasas de operaciones de emergencia a lo largo del tiempo y las tendencias de utilización de la cirugía mínimamente invasiva en entornos de urgencia y emergencia. Se compararon las tasas de complicaciones generales, quirúrgicas y médicas de 30 días no ajustadas y ajustadas entre la cirugía abierta y la mínimamente invasiva. RESULTADOS: Se identificaron un total de 2.219 pacientes. De ellos, 1.515 pacientes (68,3%) fueron intervenidos de urgencia y 704 (31,7%) de emergencia. Los casos emergentes disminuyeron con el tiempo (21% en 2006 a 8% en 2018; p <0,0001). Sin embargo, la tasa de cirugías urgentes no ha cambiado significativamente (42% en 2011 a 46% en 2018, p = 0,44). Se ofreció cirugía mínimamente invasiva al 70% de los pacientes del grupo urgente (1.058 / 1.515) y al 22,6% de las emergencias (159/704). En general, la cirugía mínimamente invasiva se utilizó cada vez más durante el período de estudio en grupos urgentes (38% en 2011 a 71% en 2018; p <0,0001) y emergentes (0% en 2005 a 42% en 2018; p <0,0001). En comparación con la cirugía mínimamente invasiva, la cirugía abierta se asoció con un mayor riesgo de complicaciones generales, quirúrgicas, sépticas y hospitalización prolongada. LIMITACIONES: Carácter retrospectivo del análisis. CONCLUSIÓNES: Basado en un análisis nacional de los Estados Unidos, la cirugía mínimamente invasiva se ha implementado de manera creciente y segura para las indicaciones emergentes y urgentes de la colitis ulcerosa. Si bien la suma de casos emergentes y urgentes permaneció igual durante el período de estudio, los casos de emergencia disminuyeron significativamente, lo que puede estar relacionado con mejores opciones de tratamiento médico y un enfoque de equipo colaborativo y especializado.

S953 Validation of AGA Risk Factors for Prediction of IBD Severity
INTRODUCTION: Vulvar involvement is a rare complication of Crohn's disease (CD). The optimal treatment of vulvar CD is unknown. METHODS: We conducted a 25-year retrospective cohort study of vulvar CD from 3 referral centers. Clinical features and outcomes were studied. RESULTS: Fifty patients were identified. The most common vulvar symptoms were pain (74%), edema (60%), ulcerations (46%), nodules (36%), and abscess (34%). Medical management leading to symptomatic improvement varied, and 5 patients ultimately required surgery. DISCUSSION: Vulvar CD manifests with a broad spectrum of symptoms. Aggressive medical management was frequently effective, although surgery was required in 10% of cases.
The Development and Initial Findings of A Study of a Prospective Adult Research Cohort with Inflammatory Bowel Disease (SPARC IBD)
Abstract Background Clinical and molecular subcategories of inflammatory bowel disease (IBD) are needed to discover mechanisms of disease and predictors of response and disease relapse. We aimed to develop a study of a prospective adult research cohort with IBD (SPARC IBD) including longitudinal clinical and patient-reported data and biosamples. Methods We established a cohort of adults with IBD from a geographically diverse sample of patients across the United States with standardized data and biosample collection methods and sample processing techniques. At enrollment and at time of lower endoscopy, patient-reported outcomes (PRO), clinical data, and endoscopy scoring indices are captured. Patient-reported outcomes are collected quarterly. The quality of clinical data entry after the first year of the study was assessed. Results Through January 2020, 3029 patients were enrolled in SPARC, of whom 66.1% have Crohn’s disease (CD), 32.2% have ulcerative colitis (UC), and 1.7% have IBD-unclassified. Among patients enrolled, 990 underwent colonoscopy. Remission rates were 63.9% in the CD group and 80.6% in the UC group. In the quality study of the cohort, there was 96% agreement on year of diagnosis and 97% agreement on IBD subtype. There was 91% overall agreement describing UC extent as left-sided vs extensive or pancolitis. The overall agreement for CD behavior was 83%. Conclusion The SPARC IBD is an ongoing large prospective cohort with longitudinal standardized collection of clinical data, biosamples, and PROs representing a unique resource aimed to drive discovery of clinical and molecular markers that will meet the needs of precision medicine in IBD.
Letter: safety of immune checkpoint inhibitors in patients with pre‐established microscopic colitis—a single‐centre experience
INTRODUCTION: Gastroenterologists at all levels of practice benefit from formal mentoring. Much of the current literature on mentoring in gastroenterology is based on expert opinion rather than data. In this study, we aimed to identify gender-related barriers to successful mentoring relationships from the mentor and mentee perspectives. METHODS: A voluntary, web-based survey was distributed to physicians at 20 academic institutions across the United States. Overall, 796 gastroenterology fellows and faculty received the survey link, with 334 physicians responding to the survey (42% response rate), of whom 299 (90%; 129 women and 170 men) completed mentorship questions and were included in analysis. RESULTS: Responses of women and men were compared. Compared with men, more women preferred a mentor of the same gender (38.6% women vs 4.2% men, P < 0.0001) but less often had one (45.5% vs 70.2%, P < 0.0001). Women also reported having more difficulty finding a mentor (44.4% vs 16.0%, P < 0.0001) and more often cited inability to identify a mentor of the same gender as a contributing factor (12.8% vs 0.9%, P = 0.0004). More women mentors felt comfortable advising women mentees about work-life balance (88.3% vs 63.8%, P = 0.0005). Nonetheless, fewer women considered themselves effective mentors (33.3% vs 52.6%, P = 0.03). More women reported feeling pressured to mentor because of their gender (39.5% vs 0.9% of men, P < 0.0001). Despite no gender differences, one-third of respondents reported negative impact of the COVID-19 pandemic on their ability to mentor and be mentored. DISCUSSION: Inequities exist in the experiences of women mentees and mentors in gastroenterology, which may affect career advancement and job satisfaction.
