 note = {This study was conducted to clarify the safety and efficacy of laparoscopic cholecystectomy. A total of 443 consecutive laparoscopic cholecystectomies were performed between March, 1992 and October, 1998 at Niigata City General Hospital. The overall conversion rate from laparoscopic to open cholecystectomy was 7.9% (35). Without these 35, two patients group were compared: the initial 200 cases and the late 208 cases. The average postoperative length of hospital stay was 4.9 days for the initial 200 cases and 4.6 days for the late 208 cases. The average operative time for the late 208 cases was 74 min., which was significantly shorter (p<0.001) than the time of 87 min. for the initial 200 cases. Significant morbidity occurred in 3.6% of the 443 patients, including bile duct injuries (6), bile leak (4), vascular injury (1), small bowel injury (1), and the others (5). The conversion to laparotomy for the treatment of a complication was 1.8% (8). The re-laparotomy was required for a complication in 3, one of who died of pulmonary infarction. We analyzed quality-of-life indicators for 37 unselected patients to clarify the feasibility of laparoscopic cholecystectomy. Postoperative pain was well controlled in 97% of the patients. Eighty five % of the patients returned to their jobs within 20 days after operation. Although some specific complications are associated with laparoscopic approach, laparoscopic cholecystectomy shows its overall safety and efficacy. Adequate training and experience of laparoscopic cholecystectomy is required for prevention of these complications.},
