Laparoscopy not recommended for routine appendectomy in men: results of a prospective randomized study

Abstract

Background: Laparoscopic appendectomy has now gained wider acceptance in clinical practice, particularly in the treatment of women with right iliac fossa pain. However, the precise role of laparoscopic appendectomy in men is unclear, and this study was therefore undertaken to examine this specific issue in a prospective randomized trial.

Methods: One hundred men between the ages of 16 and 65 years who had suspected appendicitis were recruited and randomized to undergo either open or laparoscopic appendectomy. Both groups were compared in terms of their clinical parameters, duration of anesthetic and operation times, postoperative pain, duration of ileus, and length of hospital stay.

Results: The histologic confirmation of appendicitis was present in 94% of the cases for both groups of patients. Laparoscopic appendectomy required significantly longer anesthetic time (72.5 minutes versus 55 minutes) and actual operating time (45 minutes versus 25 minutes) compared with open appendectomy. Postoperative pain as measured by visual analog scale on postoperative days 1 and 2 were not significantly different between the patients who underwent laparoscopic and open surgery with values of 4.7 versus 4.4 and 2.1 versus 2.2, respectively. Also no significant difference was seen between the laparoscopic and open appendectomy groups in the recovery of bowel function (24.7 hours versus 21 hours) and in the length of hospital stay (4.9 days versus 5.3 days).

Conclusions: The results of this prospective randomized trial showed that there were no significant advantages of laparoscopic appendectomy over open appendectomy for the treatment of male patients with suspected appendicitis. We recommend that the use of laparoscopy be limited to men with atypical pain of uncertain diagnosis and in obese patients.
