Abstract:Objective：To investigate the timing of operation and the selection of surgical procedure for acute biliary pancreatitis. Methods：The clinical data of 247 cases of acute biliary pancreatitis were retrospectively analysed. Results：Among 10 non-operation patients, 4 died; 12 patients underwent emergency operation, 5 had postoperative complications and 2 patients died after operation. 169 patients underwent delayed operation after effective conservative therapy and 1 patient had postoperative complication; 56 patients underwent selective operation without any postoperative complication or death. Conclusions：Early emergency operation should be performed for relief of biliary obstruction in acute biliary obstructive pancreatitis. The patients with acute non-obstructive biliary pancreatitis should undergo conservative therapy at first and then, after pancreatitis has been controlled, delayed operation or selective operation to treat the biliary pathologic condition should be performed.
