Cholecystectomy is recommended during hospitalizations for acute biliary pancreatitis (ABP). We sought to assess the population-based effectiveness of index cholecystectomy by using nationwide data. Retrospective, cohort study. All acute-care hospitals in Canada from 2007 to 2010. This study involved patients admitted for ABP in the Canadian Institutes for Health Information hospital discharge database. Cholecystectomy and therapeutic ERCP during the index admission. Rate of hospital readmissions for ABP. Among 5646 patients with ABP, 32% underwent cholecystectomy and 22% ERCP during the index admissions. Patients admitted to hospitals in the highest quartile for cholecystectomy volume were more than 10-fold likely to undergo cholecystectomy during the index admission (adjusted odds ratio 11.0; 95% confidence interval [CI], 7.4-16.5). The 12-month readmission rate for ABP was lower with cholecystectomy (5.6% vs 14.0%; P
