One hundred consecutive patients underwent laparoscopic cholecystectomy from May 1991 to February 1992 at Veterans General Hospital--Kaohsiung. Ninety-seven of them presented on an elective basis, including eight patients undergoing endoscopic sphincterotomy with extraction of common bile duct stone before laparoscopic cholecystectomy. The remaining 3 patients were operated during acute cholecystitis episode. Two patients with biliary injuries during laparoscopic cholecystectomy were converted to laparotomy, with a conversion rate of 2%. Intraoperative cystic cholangiogram was done selectively in 7 patients. Major complications occurred in 3 patients, including two biliary injuries and one residual CBD stone. Minor complications of wound infection were found in 7 patients. The overall morbidity rate was 10%. No operative mortality was found. Mean operation time was 112 minutes and mean blood loss was 90 ml. The mean hospital stay (3.1 days) and the mean time of returning to normal activity (14.7 days) were longer than those of Western series, but were shorter than those of open cholecystectomy. Laparoscopic cholecystectomy is a safe and effective procedure that can be performed with minimal risk. However, the importance of accurate preoperative screening and surgical experience should be emphasized for this new procedure. In patients with gall stone plus CBD stone, combined endoscopic sphincterotomy with extraction of CBD stone and laparoscopic cholecystectomy may offer a new therapeutic approach but the long term effect of endoscopic sphincterotomy needs further evaluation.

A total of 4056 consecutive patients operated for benign biliary tract disease between January 1983 and June 1990 were reviewed retrospectively. There were 71 in-hospital deaths, representing 1.75% of morality rate. Cholecystectomy was performed in 2275 patients; common bile duct exploration was carried out in 1494, with operative mortality rates of 0.4% and 3.1% respectively. Sepsis was the leading cause of mortality. The second common cause of death was hepatic failure, and respiratory failure the third. Cardiovascular problems accounted for 11.3% of death, which was much lower than reports from western series. Other causes of mortality included hypovolemic shock, anaphylactic shock, epilepsy and hypoglycemia. Of the total 4056 patients, 28.5% underwent emergency surgery. The mortality rate for emergency surgery was 3.6 times higher than for those who underwent elective operations (p less than 0.005) Significantly higher mortality rates were also seen for those aged over 70 years and of male gender. Because the mortality rate of patients who underwent emergency operation due to acute inflammatory or obstructive complications were much higher than that of elective operation group, we suggested early surgical intervention for the symptomatic patients before complications occurred.
