In those clinical settings where surgical expertise and equipment are available and affordable, diagnostic laparoscopy and LA (either in combination or separately) seem to have various advantages over OA. Some of the clinical effects of LA, however, are small and of limited clinical relevance. In spite of the mediocre quality of the available research data, we would generally recommend to use laparoscopy and LA in patients with suspected appendicitis unless laparoscopy itself is contraindicated or not feasible. Especially young female, obese, and employed patients seem to benefit from LA.
Prospective randomized comparison of open versus laparoscopic appendectomy in men.
A prospective, randomized trial was performed to compare open appendectomy with laparoscopic appendectomy in men with a clinical diagnosis of acute appendicitis. Sixty-four patients with a median age of 25 years (range 18-84 years) were randomized to open appendectomy (n = 31) or laparoscopic (n = 33) appendectomy. Of the 64 men, 56 (87.5%) had appendicitis (27 open, 29 laparoscopic procedures). The mean operating times were 50.6 +/- 3.7 minutes (+/- SEM) for open and 58.9 +/- 4.0 minutes for laparoscopic appendectomy (p = 0.13). Five (15%) patients randomized to laparoscopic appendectomy had an open operation. The mean postoperative hospital stay was significantly longer for open appendectomy (3.8 +/- 0.4 days) than for laparoscopic appendectomy (2.9 +/- 0.3 days) (t = 2. 05,df = 62,p = 0.045). The complication rate after open appendectomy (25.8%) was not significantly different from that after laparoscopic appendectomy (12.1%). There was a single postoperative death due to a pulmonary embolus in the laparoscopic group and a single death due to cardiac and renal failure in the open group. The mean time to return to normal activities was significantly longer following open appendectomy (19.7 +/- 2.4 days) than after laparoscopic appendectomy (10.4 +/- 0.9 days), (t = 3.75,df = 49,p = 0.001). In conclusion, laparoscopic appendectomy in men has significant advantages in terms of a more rapid recovery compared to open appendectomy. There were no significant disadvantages to laparoscopic appendectomy compared to open appendectomy.
