Elective laparoscopic cholecystectomy has become established as the procedure of choice for the treatment of symptomatic cholecystolithiasis while the application of this method for acute cholecystitis has been propagated with restrainment. In a prospective study 114 conventional (right subcostal incision) and 102 laparoscopic cholecystectomies for this indication were compared. The overall complication rate amounted 10.7% for conventional cholecystectomy and 8.9% for laparoscopic cholecystectomy. The rate of conversion was 9.2%. Due to the fact that intraoperative cholangiography was carried out in 60% of conventional cholecystectomies and in only one of laparoscopic procedures the arithmetic advantage of minimally invasive technique with respect to blood loss and operating time does not allow final conclusions. These patients however recovered clearly faster and could be discharged after an average of 5.2 +/- 4.2 postoperative days, while the hospitalisation after conventional operations amounted to 7.6 +/- 3.8 days (p < 0.001).
