From February to May in 1991, 100 cases of gallstones underwent the attempt of laparoscopic cholecystectomy. There were two failures owing to extensive adhesion. The operative time was 72.5 +/- 32 minutes in the first 50 cases, and 46.9 +/- 15 minutes thereafter. Among them 8 cases were coelio-drained for 24 hours with very little thin bloody drainage. There were not postoperative complications. The hospital stay was 3-7 days. All patients were back to their normal daily-work within 10 days. Hence this new type of cholecystectomy is characterized by less trauma and pain, and fast postoperative recovery.
