BACKGROUND AND AIM Despite higher rates of gallstones in patients with cirrhosis, there are no population-based studies evaluating outcomes of acute biliary pancreatitis (ABP). Therefore, we sought to evaluate the predictors of early readmission and mortality in this high-risk population. METHODS We utilized the Nationwide Readmission Database (2011-2014) to evaluate all adults admitted with ABP. Multivariable logistic regression models were used to assess independent predictors for 30-day readmission, index admission mortality, and calendar year mortality. RESULTS Among 184 611 index admissions with ABP, 4344 (2.4%) subjects had cirrhosis (1649 with decompensation). Subjects with cirrhosis, when compared with those without, incurred higher rates of 30-day readmission (20.9% vs 11.2%; P

Background: Concerns about the risk of bowel perforation for same-day computed tomography colonography (CTC) following an incomplete colonoscopy with polypectomy may lead to unnecessarily postponing the CTC. Objective: The objective of this article is to describe the complications including colon perforations associated with sameday CTC in a cohort who had polypectomies but an incomplete colonoscopy. Design: We conducted a retrospective study. Setting: Our study took place in a single, tertiary referral center. Patients: We studied consecutive patients who had CTC the same day as an incomplete colonoscopy with polypectomy. Interventions: Interventions included optical colonoscopy (OC), endoscopic polypectomies, and same-day CTC. Main outcome measurements: Our main outcome measurements included perforation rate with long-term follow-up. Results: A total of 3% of patients undergoing colonoscopy from January 2008 to December 2012 had same-day CTC following incomplete OC, and 72 polypectomies were performed in 34 (or 17%) of these patients. Incomplete colonoscopies were due to colon tortuosity and looping (25), severe angulations (five), colon mass (two), colon stenosis (one), bradycardia (one). Fifty-three percent of the OCs were screening for colon neoplasia, 29% diagnostic and 18% were surveillance of colon polyps. Most polyps were � 5mm, and found in the left colon. There were no reported complications or perforations associated with same-day CTCs during short- and long-term follow-up. Limitations: Limitations of our analysis included retrospective single-center design, small number of patients for the occurrence, referral to same-day CTC was not standardized, inability to establish safety of CTC for specific scenarios such as after complex polypectomies, strictures, or advanced IBD. Conclusions: Radiologists’ apprehension to perform a CTC the same day as an incomplete colonoscopy following polypectomies because of perceived risk of perforation may be unfounded. More data are needed to determine the safety of sameday CTC in patients with high-risk findings during colonoscopy such as a stricture, severe IBD, and after complex polypectomies.
