Laparoscopic management of acute cholecystitis.

The role of laparoscopic surgery in patients presenting with acute cholecystitis remains controversial. From September 1989 through August 1992, a total of 720 patients underwent cholecystectomy. Ninety-six were unplanned admissions with a clinical diagnosis of acute cholecystitis. Laparoscopic surgery was attempted in 83 patients. Thirteen individuals were not offered laparoscopy because of the surgeon's inexperience. Twenty-two (27%) patients required the laparoscopic procedure converted to an open laparotomy. The mean postoperative hospital stay for patients undergoing laparoscopic cholecystectomy was 3.3 days versus 6.8 days for the laparotomy group. There was no mortality and no bile duct or major vascular injuries in either group. The overall operative morbidity rate was 16.9%. Laparoscopic cholecystectomy appears to be a safe and beneficial option in selected patients with acute cholecystitis. A low threshold for conversion to laparotomy appeared to be an important factor in maintaining a low incidence of operative complications. Several modifications to the technique of laparoscopic cholecystectomy have evolved over the 3-year study period and are described.
