RESUMO
This survey reviews 815 consecutive patients undergoing surgery for benign biliary disease. There were no deaths following elective operations and the overall mortality was 0.7 per cent. One-third of patients had one or more complications. The mortality in patients having common bile duct exploration (n = 160) by one or more methods was 2.5 per cent (4 patients) with 46 per cent of these patients having complications. Of 95 patients undergoing duct exploration and postoperative T-tube cholangiography, 7 had unexpected residual calculi after initial cholecystectomy. Five have had further surgery to clear the duct. All patients having duct surgery alone for retained stones (n = 24) had previously had cholecystectomy with or without supraduodenal duct exploration. Of all patients undergoing choledochoduodenostomy or transduodenal sphincter exploration only one has returned with evidence of retained calculi. Patients with choledocholithiasis were examined in an attempt to identify a high risk group. These were found to be elderly patients, having emergency surgery for sepsis and on whom more than one duct procedure was performed (mortality 10 per cent).
