Randomized trial of laparoscopic cholecystectomy and mini-cholecystectomy.

Three hundred and ten patients having elective cholecystectomy were randomized to either laparoscopic cholecystectomy or mini-cholecystectomy. There were 155 patients in each group. Conversion to open cholecystectomy was significantly more common with laparoscopic cholecystectomy (13 versus 4 per cent) and complications were significantly more frequent with laparoscopic cholecystectomy (9 versus 3 per cent). If laparoscopic cholecystectomy was successful, hospital stay was significantly shorter than for mini-cholecystectomy (2 versus 3 days respectively), but overall the hospital stay was not significantly different. Postoperative analgesia requirements were reduced and return to normal activities and to work were faster after laparoscopic cholecystectomy. There was no significant cost difference between the two procedures.
