271 Factors Affecting the Decision to Perform Same Admission Cholecystectomy Following Biliary Pancreatitis: A Comparative Study

Same admission cholecystectomy is recommended following biliary pancreatitis to prevent recurrent attacks. However, delaying surgery may be appropriate in certain cases. We aimed to compare patient and admission factors between those undergoing same admission and delayed cholecystectomy. Method Admissions with confirmed biliary pancreatitis over a 5-year period were included. Demographics, co-morbidities, need for intensive treatment unit (ITU) admission and endoscopic retrograde cholangiopancreatography (ERCP) were analysed to determine differences between those undergoing same admission and delayed cholecystectomy. Results 55 and 46 patients underwent same admission and delayed cholecystectomy respectively. There was no difference in age (59 vs 59.2 years, p = 0.947), history of cardiovascular disease (38.2 vs 34.8%, p = 0.724), diabetes (7.3 vs 8.7%, p = 0.792) anticoagulation (7.3 vs 6.5%, p = 0.882) or previous abdominal surgery (0 vs 6.25%, p = 0.05) between groups. Only need for ITU admission (5.5 vs 21.7%, p = 0.01) and ERCP (9.1 vs 28.3%, p = 0.01) were found to be statistically different between groups. Conclusions Severity of pancreatitis, rather than patient factors, alone seems to influence the decision to perform same admission cholecystectomy in those with biliary pancreatitis. Further work is needed to understand surgeon factors in the decision-making process.
