Prospective randomized multicentre study of laparoscopic versus open appendicectomy.

Abstract

BACKGROUND: A prospective randomized multicentre study was performed to compare the outcome of laparoscopic and open appendicectomy in patients with suspected acute appendicitis. METHODS: A total of 523 patients was randomized, but because of 23 withdrawals the outcome in 500 patients is reported, 244 in the laparoscopic group and 256 in the open group. RESULTS: Patients having laparoscopic appendicectomy recovered more quickly than those having open surgery (13 versus 21 days, P < 0.001). There was no significant difference in duration of sick leave after operation (laparoscopic group 11 days versus open group 14 days). Postoperative pain (at 24 h, 7 days and 14 days) was less after laparoscopic operations and a functional index 1 week after operation was more favourable in these patients (P < 0.001). Operating time was significantly longer in the laparoscopic group (60 versus 35 min, P < 0.01). Hospital stay and complications did not differ between the groups. Thirty laparoscopic procedures (12 per cent) were converted to open appendicectomy. CONCLUSION: Laparoscopic appendicectomy is as safe as open appendicectomy and has the advantage of allowing a quicker recovery.
