INTRODUCTION: Learning styles among gastroenterology providers have not been reported and may have implications in improving continuing medical education (CME). This study aims to 1) evaluate learning styles among gastroenterology providers participating in a board review course, 2) assess self-reported burnout, and 3) determine if demographic information, practice style, or burnout was associated with specific learning styles. METHODS: Participants at the 2018 Mayo GI and Hepatology Board Review Course had the opportunity to participate in an anonymous, survey-based study evaluating learning styles and burnout. Demographic and practice information, reason for participating in the course, questions regarding burnout and callousness, and the Kolb Learning Style Inventory (KLSI) (v3.1, Korn Ferry Hay Group, Boston, MA) were collected. Associations between demographic data, burnout, and learning styles were assessed using Fisher’s exact test. RESULTS: A total of 71 of 230 participants elected to participate and 47 completed the KLSI. Median age range was 41-50 years, 31 (43.7%) were female, and 60 (84.5%) had MD or DO degree. All regions of the United States were represented and 4 participants were from outside of the US. Reasons for participation included new certification (12.7%), recertification (45.1%), not passing prior board certification (4.2%), and general knowledge (38%). Burnout was noted by 27 (38%), callousness by 19 (26.8%), and both by 9 (12.7%). Kolb learning styles were diverging in 27.7%, assimilating in 31.9%, converging in 27.7%, and accommodating in 12.8%. There were no associations with demographics, practice type or reason for taking the course with specific learning styles; however, more frequent markers of burnout were associated with the accommodating learning style (50% burnout only, 33% callous only, and 16.7% reporting both; P = .03). CONCLUSION: All learning styles are represented at the studied board review course and are dispersed throughout ages, sex, geography, and practice style. This highlights the importance of a transition from lecture-based CME to more varied education modalities. Indices of self-reported burnout are seen frequently in this cohort, and seem to have increased association with the accommodating learning style. Future study with more participants is needed to further understand learning styles and burnout in gastroenterology providers, with the aim of improving CME.

INTRODUCTION: Treatment options for patients with moderate-severe ulcerative colitis (UC) are increasing. The appropriateness of their use in mild-moderate UC is less clear, as is the role of surgical intervention. Our aim was to define the appropriateness of therapeutic options in a range of clinical scenarios in mild-moderate UC METHODS: We applied the RAND/UCLA Appropriateness Method to rate appropriateness of treatment choices in patients with mild-moderate UC; severe disease (likely to need hospitalization or surgery within 2 weeks) was excluded. A literature review was presented to the BRIDGe group, a panel of 13 IBD specialists, as well as 1 external IBD expert and 2 IBD surgical experts. 12 chapters were constructed including failed 5-ASA, steroid or thiopurine therapy, and primary/secondary non-response to biologics or tofacitinib. Scenarios were also divided by disease extent (proctitis vs more extensive) and activity (mild vs moderate) creating 260 scenarios in all. Panellists used a modified Delphi method to anonymously rate the appropriateness of a therapy on a 1-9 scale (1-3 not appropriate, 4-6 uncertain, 7-9 appropriate). Disagreement was assessed using a validated index (DI) and was defined as a DI > 1. The panellists then convened in person to discuss areas of disagreement, followed by a second round of rating. Scenarios rated a median of 7 or higher were deemed appropriate and those rated 3 or lower were deemed inappropriate. Scenarios rated 4-6 were considered uncertain, as were any with a DI > 1 RESULTS: Appropriateness was agreed in 131 and inappropriateness in 47 scenarios. Greatest disagreement was around the use of thiopurines, but no scenario had a DI > 1. There were 82 scenarios were rated uncertain. Biologics and tofacitinib were more likely to be rated appropriate for treatment resistance and greater disease activity; disease extent less likely to influence decision making. Surgery was felt to be appropriate in 8 scenarios, generally in more extensive and active disease that had failed to respond to medical therapy. Surgery was felt to be inappropriate in 16 scenarios and was uncertain in 24 CONCLUSION: Although there was little disagreement amongst an expert panel of IBD physicians and surgeons, there remained uncertainty about the use of medical and surgical therapy in nearly one third of situations in patients with mild-moderate UC. These results could be used to guide the design of clinical trials for these patient groups in order to guide best practice.

INTRODUCTION: Patients with inflammatory bowel disease (IBD), whether Crohn's disease (CD) or ulcerative colitis (UC), have known alterations in the enterohepatic circulation of bile acids (BA) that may contribute to chronic diarrhea, but the fecal BA patterns are not well defined. We aimed to audit all patients with IBD who had fecal BA measurements as part of evaluation of chronic diarrhea at a tertiary care center. METHODS: Methods: 65 patients with IBD (18 with UC and 47 with CD) were evaluated at a single center and underwent measurements of fecal total and individual BAs based on a 48-hour collection performed at the end of a 4-day, 100-gram fat diet. The electronic medical records were interrogated to obtain type of IBD, disease activity, location of disease, prior surgery, IBD related therapies, presenting symptoms, and response to treatment with BA sequestrants. Bile acid diarrhea (BAD) diagnosis was based on >10% primary BAs, >4% primary BAs + >1,000 µmol/48 h, or total fecal BAs >2,337 µmol/48 h. IBD disease activity was based on radiologic, endoscopic and histologic parameters. Data are reported as mean ± standard error of the mean (SEM). RESULTS: Table 1 summarizes the patterns of BAD in our cohort with IBD. Figure 1 demonstrates the mean ± SEM of total fecal BAs and % primary BAs in each group of IBD patients. Among patients with UC, 10 had poorly controlled disease and 8 had well controlled disease, and both cohorts had elevated primary BAs (mean 28.9% ± 12.5%; 34.6% ± 21%, respectively). All patients with an ileal pouch anal anastomosis (IPAA) had elevated total fecal BAs (BADt) compared to those with an intact colon. In patients with CD, those with ileal resections had elevated BADt and % primary BAs (6263 µmol/48 h ± 1012 µmol/48 h; 79% ± 5.9%, respectively). Patients with an intact ileum, had elevated % primary BAs regardless of disease activity: controlled CD 34.7% ± 9.3%; poorly controlled CD 57.8% ± 9.5%; 15 out of 47 patients with CD were started on BA sequestrants with a positive response in 10/15. CONCLUSION: Discussion: BAs may play a role in the pathophysiology of chronic diarrhea in patients with IBD, regardless of inflammatory disease activity. Future studies are required to assess the impact of fecal bile acid testing and treatment with BA sequestrants on inflammation and chronic diarrhea in patients with IBD.

BACKGROUND: The evidence regarding the association of preoperative biologic exposure and postoperative outcomes remains controversial for both antitumor necrosis factor agents and vedolizumab and largely unknown for ustekinumab. OBJECTIVE: The purpose of this study was to determine differences in the rates of 30-day postoperative overall infectious complications and intra-abdominal septic complications among the 3 classes of biologic therapies as compared with no biologic therapy. DESIGN: This was a retrospective review. SETTINGS: The study was conducted at an IBD referral center. PATIENTS: Adult patients with Crohn’s disease who received an antitumor necrosis factor, vedolizumab, ustekinumab, or no biologic therapy within 12 weeks of a major abdominal operation between May 20, 2014, and December 31, 2017, were included. MAIN OUTCOMES MEASURES: Thirty-day overall postoperative infectious complications and intra-abdominal septic complications were measured. RESULTS: A total of 712 patients with Crohn’s disease were included; 272 patients were exposed to an antitumor necrosis factor agents, 127 to vedolizumab, 38 to ustekinumab, and 275 to no biologic therapy within the 12 weeks before an abdominal operation. Patients exposed to a biologic were more likely to be taking a concurrent immunomodulator, but there was no difference in concurrent corticosteroid usage. The particular class of biologic was not independently associated with total overall infectious complications. Vedolizumab was associated with an increased rate of intra-abdominal sepsis on univariate analysis but not on multivariable analysis. Combination immunosuppression was associated with both an increased rate of overall postoperative infectious complications and intra-abdominal sepsis. LIMITATIONS: The study was limited by its retrospective design and single-center data. CONCLUSIONS: The overall rate of total infectious complications or intra-abdominal septic complications was not increased based on preoperative exposure to a particular class of biologic. Rates increased with combination immunosuppression of biologic therapy with corticosteroids and previous abdominal resection. See Video Abstract at http://links.lww.com/DCR/B24. BIOLÓGICOS Y COMPLICACIONES POSTOPERATORIAS DE 30 DÍAS DESPUÉS DE LAS OPERACIONES ABDOMINALES PARA LA ENFERMEDAD DE CROHN: ¿EXISTEN DIFERENCIAS EN LOS PERFILES DE SEGURIDAD?: ANTECEDENTES: La evidencia sobre la asociación de la exposición biológica preoperatoria y los resultados postoperatorios sigue siendo controvertida controversial tanto para los agentes del factor de necrosis tumoral (anti-TNF) como para el vedolizumab, y en gran parte desconocida para el ustekinumab. OBJETIVO: Determinar las diferencias en las tasas de complicaciones infecciosas generales postoperatorias de 30 días y complicaciones sépticas intraabdominales entre las tres clases de terapias biológicas en comparación con ninguna terapia biológica. DISEÑO: Revisión retrospectiva. AMBIENTE: centro de referencia de la enfermedad inflamatoria intestinal. PACIENTES: Pacientes adultos con enfermedad de Crohn que recibieron un factor de necrosis antitumoral, vedolizumab, ustekinumab o ningún tratamiento biológico dentro de las 12 semanas de una operación abdominal mayor entre el 5/20/2014 y el 12/31/2017. PRINCIPALES MEDIDAS DE RESULTADOS: Complicaciones infecciosas postoperatorias generales de 30 días, complicaciones sépticas intraabdominales. RESULTADOS: Se incluyeron setecientos doce pacientes con enfermedad de Crohn; 272 pacientes fueron expuestos a un anti-TNF, 127 a vedolizumab, 38 a ustekinumab y 275 a ninguna terapia biológica dentro de las 12 semanas previas a una operación abdominal. Los pacientes expuestos a un producto biológico tenían más probabilidades de tomar un inmunomodulador concurrente, pero no hubo diferencias en el uso simultáneo de corticosteroides. La clase particular de productos biológicos no se asoció de forma independiente con las complicaciones infecciosas totales. Vedolizumab se asoció con una mayor tasa de sepsis intraabdominal en el análisis univariable, pero no en el análisis multivariable. La inmunosupresión combinada se asoció tanto con una mayor tasa de complicaciones infecciosas postoperatorias generales como con sepsis intraabdominal. LIMITACIONES: Diseño retrospectivo, datos de centro único. CONCLUSIONES: La tasa general de complicaciones infecciosas totales o complicaciones sépticas intraabdominales no aumentó en función de la exposición preoperatoria a una clase particular de productos biológicos. Las tasas aumentaron con la combinación de inmunosupresión de la terapia biológica con corticosteroides y resección abdominal previa. Vea el Resumen del Video en http://links.lww.com/DCR/B24.

Abstract Background We aim to assess the impact of a multidisciplinary inflammatory bowel disease (IBD) conference on the management of patients with complex IBD. Methods Data were collected during each conference from February 2017 through October 2018 with chart review performed at 6 months to determine if conference recommendations were successfully implemented. Results Eighty-five patients were discussed. The presenting diagnosis was changed by 11.8%. Recommendations for further testing, medical therapy, and surgery were successfully implemented in 77.1%, 98.1%, and 88.4%, respectively. Conclusions This study supports the role of IBD multidisciplinary conferences in the management of patients with complex IBD.

Abstract Introduction The impact of ustekinumab on adverse postoperative outcomes in Crohn’s disease (CD) remains largely unknown. We determined the difference in 90-day postoperative complication rates among CD patients exposed to ustekinumab within 12 weeks prior to an abdominal operation as compared to patients not exposed to biologic therapy. Methods A retrospective chart review of all adults with CD who underwent an abdominal operation between October 1, 2017 and December 31, 2018 at a single tertiary medical center was performed. Data collection included patient demographics, concurrent immunosuppression, serum laboratory values, operative values, and 90-day outcomes including superficial surgical site infection (sSSI), intra-abdominal sepsis, overall infectious complications, readmission, and reoperation rates. The primary outcome was the 90-day rate of intra-abdominal sepsis. Results Fifty-seven CD patients received ustekinumab and 277 received no biologic therapy in the 12 weeks prior to major abdominal surgery. Ustekinumab-exposed patients were younger, less likely to have diabetes mellitus or active tobacco exposure, were more often obese, and more often taking a concurrent immunomodulator. Ustekinumab remained an independent predictor of intra-abdominal sepsis on multivariable logistic regression. Immunomodulator exposure was associated with significantly increased rates of sSSI and overall complication rates. Conclusions Ustekinumab is associated with increased rates of 90-day postoperative intra-abdominal sepsis following a major abdominal operation for CD.

Background and aims: Patient-reported outcomes (PROs) will become increasingly important as primary endpoints in future clinical trials. We aimed to evaluate the relationship between health-related quality of life (HRQoL) and the combination of patient-reported clinical symptoms (ClinPRO2) and Mayo endoscopic subscore (MES) in patients with ulcerative colitis (UC). Methods: We conducted a prospective cross-sectional study of 90 consecutive UC patients who were scheduled for sigmoidoscopy or colonoscopy. All patients completed the following questionnaires: (1) self-rated rectal bleeding and stool frequency (ClinPRO2); (2) Short Inflammatory Bowel Disease Questionnaire (SIBDQ); (3) European Quality of Life 5-Dimensions 3-Level (EQ5D3L); (4) Work Productivity and Activity Impairment questionnaire (WPAI); (5) Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F); and (6) Hospital Anxiety and Depression Scale (HADS). The endoscopic images were graded according to the MES. “No symptoms” was defined as a symptom score of 0, and “mucosal healing” was defined as MES score of 0–1. Correlations between the combined ClinPRO2 and MES with HRQoL were assessed using Spearman’s correlation coefficients. Results: The combination of the ClinPRO2 and MES was well correlated to SIBDQ (r = −0.70), EQ5D3L (r = −0.51), WPAI (r = 0.62), FACIT-F (r = −0.58), and HADS-depression (r = 0.45). SIBDQ scores had strong correlations with FACIT-F (r = 0.86), WPAI (r = −0.80), and HADS-depression (r = −0.75) (p < 0.05 for all correlations). Patients with no symptoms reported the greatest all HRQoL scores. Conclusions: In patients with ulcerative colitis, the combination of a ClinPRO2 and the MES had good correlation with the SIBDQ. In addition, SIBDQ was well correlated to the various HRQoL.

Background: : The isolated effect of vedolizumab on increased postoperative complications remains debated, similar to the controversial data on anti-TNF and postoperative complications. Objective: : To determine the risk of vedolizumab on postoperative complications. Method:: A review of the literature available to date on studies comparing postoperative outcomes in vedolizumab-treated versus non-vedolizumab-treated patients was performed. Studies were stratified by those which combined all inflammatory bowel disease together, those specifically focusing on Crohn’s disease or ulcerative colitis individually, and those which included pediatric patients alone. Results:: The data remains controversial in both the adult and pediatric literature regarding the association of vedolizumab and increased postoperative complications. The strongest association between vedolizumab and an increased risk of postoperative infectious complications seems to be in the Crohn’s disease literature. Conclusion:: Vedolizumab may be associated with an increased risk of postoperative infectious complications in Crohn’s disease, but the literature remains controversial due to difficulty in isolating the effect of the biologic alone in a chronically ill, heterogeneous patient population who are on multiple medications including corticosteroids.

Abstract Background and Aims Inflammation of the pouch after ileal pouch-anal anastomosis (IPAA) can significantly impact quality of life and be difficult to treat. We assessed the effectiveness and safety of vedolizumab in Crohn’s disease (CD) of the pouch and chronic antibiotic-dependent or antibiotic-refractory pouchitis. Methods This was a retrospective, multicenter cohort study at 5 academic referral centers in the United States. Adult patients with endoscopic inflammation of the pouch who received vedolizumab were included. The primary outcome was clinical response at any time point. Secondary outcomes included clinical remission, endoscopic response, and remission. Univariate analysis and multivariate analysis were performed for the effect of the following variables on clinical response: fistula, onset of pouchitis less than 1 year after IPAA, younger than 35 years old, gender, previous tumor necrosis factor inhibitor-alpha use, and BMI &gt;30. Results Eighty-three patients were treated with vedolizumab for inflammation of the pouch between January 2014 and October 2017. Median follow-up was 1.3 years (interquartile range 0.7–2.1). The proportion of patients that achieved at least a clinical response was 71.1%, with 19.3% achieving clinical remission. Of the 74 patients with a follow-up pouchoscopy, the proportion of patients with endoscopic response and mucosal healing was 54.1% and 17.6%, respectively. Patients who developed pouchitis symptoms less than 1 year after undergoing IPAA were less likely to respond to vedolizumab, even after controlling for other risk factors. Conclusions Vedolizumab is safe and effective in the management of CD of the pouch and chronic pouchitis. Further studies are needed to compare vedolizumab with other biologic therapies for pouchitis and CD of the pouch.
