RESUMO
BACKGROUND: It is essential to accurately distinguish small benign hyperplastic colon polyps (HP) from sessile serrated lesions (SSL) or adenomatous polyps (TA) based on endoscopic appearances. Our objective was to determine the accuracy and inter-observer agreements for the endoscopic diagnosis of small polyps. METHODS: High-quality endoscopic images of 30 small HPs, SSLs, and TAs were used randomly to create two-timed PowerPoint slide sets-one with and another one without information on polyp size and location. Seven endoscopists viewed the slides on two separate occasions 90 days apart, identified the polyp type, and graded their confidence level. Overall and polyp-specific accuracies were assessed for the group and individual endoscopists. Chi-square tests and Kappa (κ) statistics were used to compare differences as appropriate. RESULTS: When polyp size and location were provided, overall accuracy was 67.1% for TAs, 50.0% for SSLs, and 41.4% for HPs; the corresponding accuracies were 60%, 44.3%, and 34.3% when polyp size and location were withheld (p < .001). Inter-observer agreement was moderate for TAs (κ = 0.50) and fair for SSLs (κ = 0.26) and HPs (κ = 0.29); the corresponding inter-observer agreements were 0.44, 0.31, and 0.17 with polyp size and location withheld. Accuracy was not affected by knowledge of polyp size, location, or confidence level. Endoscopists with ≥ 10 years (vs. < 10 years) of colonoscopy experience had marginally higher (56% vs. 40%, p = 0.05) accuracy for SSL diagnosis. CONCLUSIONS: The ability to distinguish between small TAs, SSLs, and HPs on their endoscopic appearance is poor regardless of the endoscopists' knowledge of polyp size and location.

GOALS: To compare the clinical outcomes of different protocols for fecal microbiota transplantation (FMT) in two community hospitals with similar patient demographics. BACKGROUND: FMT is commonly performed for recurrent or refractory Clostridioides difficile infection (rCDI). The clinical efficacy of FMT for this indication has been well established. However, there has been no standardization or optimization of the amount of fecal material, method of feces preparation, or route of delivery for FMT. STUDY: In this retrospective study, patients with rCDI received FMT using commercially available frozen fecal preparation (22.7 g) at Center A and locally prepared fresh fecal filtrate (30-50 g) at Center B. The primary outcome was defined as complete resolution of clinical symptoms related to rCDI after at least 8 weeks of follow-up. RESULTS: Fifty patients from each center were included in the study. Clinical success after initial FMT with lower-volume frozen fecal preparation at Center A was 32/50 (64.0%) compared to 49/50 (98.0%) with higher-volume fresh fecal filtrate at Center B (p < 0.0001). Seventeen patients in Center A and 1 patient in Center B underwent at least one repeat FMT. Overall clinical success was achieved in 43/50 (86%) of patients in Center A and 50/50 (100%) in Center B (p = 0.012). CONCLUSIONS: Our results suggest superior clinical efficacy of a larger amount of fresh fecal filtrate over a smaller amount of commercially available frozen fecal preparation. Further studies are needed to examine the effect of varying amounts of feces and the optimal protocol for FMT in patients with rCDI.

BACKGROUND: Readmissions are being increasingly used as an indicator of quality of care. We sought to identify risk factors for 30-day readmission in hospitalized patients with inflammatory bowel disease. METHODS: Patients with inflammatory bowel disease hospitalized between 2004 and 2013 at the University of Maryland were identified. Demographic and clinical information were extracted from the medical record for each admission. Multivariate logistic regression was performed to determine the association between these variables and readmission. RESULTS: One thousand two hundred thirteen admissions were identified in 498 patients; 232 (19.1%) index admissions were followed by a 30-day readmission. Mean age was 39.4 ± 14.5 years. Approximately 70% of the population was white, 60% were women, and 67.5% had Crohn's disease. Concurrent congestive heart failure and chronic obstructive pulmonary disease, history of steroid use, diverting ileostomy, subtotal colectomy, or a thromboembolic event during index admission, and IV antibiotics or restricted diet at discharge were associated with readmission. After adjustment, patients with congestive heart failure or chronic obstructive pulmonary disease were more likely to be readmitted (aOR 4.06 and 2.86, respectively). Underweight or obese patients were nearly twice as likely to be readmitted (aOR 1.81 and 1.72, respectively). Those with past steroid use, new ileostomy, or those who were discharged on hyperalimentation were twice as likely to be readmitted (aOR 1.90, 2.04, and aOR 1.97, respectively). CONCLUSIONS: Nineteen percentage of patients with inflammatory bowel disease treated at a referral center are readmitted within 30 days. Our results suggest that patients with comorbid medical conditions, malnutrition or obesity, a new ileostomy, past steroid use, or those discharged on hyperalimentation are at increased risk for readmission. Research is needed to determine if targeted interventions for high-risk patients decreases readmissions.

INTRODUCTION: Vedolizumab is the latest FDA-approved anti-integrin therapy for treatment of moderate-to-severe inflammatory bowel disease (IBD). The safety and efficacy of vedolizumab have been studied in short-term clinical trials. AREAS COVERED: This paper reviews the safety profile of vedolizumab compared with other biologics. It also highlights the mechanism of action of the medication. We discuss the current position of vedolizumab in our current algorithm for IBD management and comment on future prospects of the drug. EXPERT OPINION: Vedolizumab appears to be a safe and effective option in the treatment of moderate-to-severe IBD in the short term. Long-term observational studies and post-marketing safety data are needed to ascertain the long-term efficacy and side effect profile.
