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.
Randomized clinical trial of laparoscopic versus open appendicectomy for confirmed appendicitis.
Laparoscopy is safe for diagnostic and therapeutic purposes in patients with suspected acute appendicitis. This study compared recovery after laparoscopic (LA) and open appendicectomy (OA) for confirmed appendicitis, carried out by experienced surgeons in an educational setting.
                One hundred and sixty-three patients with laparoscopically confirmed appendicitis suitable for LA were randomized prospectively to either LA or OA in a blinded fashion. The primary endpoint was time to full recovery. Secondary endpoints were operating time, complications, hospital stay and functional status.
                There was no significant difference between LA and OA in time to full recovery (9 and 11 days respectively; P = 0.225). Operating time was 55 min in the LA group and 60 min in the OA group (P = 0.416). The complication rate was 8.6 and 11.0 per cent respectively (P = 0.696), and median hospital stay was 2 days in both groups (P = 0.192). Functional status was significantly better in the LA group 7-10 days after operation (P = 0.045).
                There was no difference in time to full recovery after LA and OA in patients with laparoscopically confirmed appendicitis. A trend towards better physical activity was noted after the laparoscopic procedure.
