Incidence and Management of Biliary Pancreatitis in Cholecystectomized Patients: Results of a 7-Year Study

Abstract

Data are lacking concerning the frequency of biliary acute pancreatitis in the postcholecystectomy patient. The aim of this study was to identify patients at risk for biliary pancreatitis after cholecystectomy and to describe the therapeutic management of these patients, based on an analysis of 278 unselected patients with acute pancreatitis during a 7-year period. A biliary etiology was presumed in the presence of laboratory findings of cholestasis that could not be explained by another disease, together with the absence of any other known etiology of acute pancreatitis. A biliary cause of disease was found in 132 (47%) of 278 patients. Seventeen (13%) of 132 patients had a history of cholecystectomy. Endoscopic retrograde cholangiopancreatography was performed in all patients with a suspected biliary cause of acute pancreatitis. It showed bile duct stones, microlithiasis, or sludge in 14 patients, and was consistent with typical findings at the papilla of Vater after stone passage in another three patients. No surgical bile duct exploration was necessary. One patient with severe disease and infected pancreatic necrosis died of septic multiorgan failure. ( J Gastrointest Surg 2003;7:372–377.)
