Biliary surgery in the same admission for gallstone‐associated acute pancreatitis

The clinical course of 47 patients with gallstone‐associated acute pancreatitis who had surgery during the same admission has been reviewed. In 37 patients, when the signs and symptoms of pancreatitis settled on conservative management, biliary tract surgery was safely performed during that admission without mortality. The 10 patients whose clinical condition failed to settle prior to surgery had a complicated hospital stay and a 50 per cent mortality. A revised prognostic factor grading system has been outlined in which the age factor is removed and serum transaminase levels are considered of prognostic significance only if greater than 200 u/l within 48 h of admission. This revised system gives a more accurate assessment of the severity of individual attacks of gallstone‐associated acute pancreatitis.
