Randomized clinical trial of laparoscopic versus open appendicectomy for confirmed appendicitis

Abstract

Abstract Background 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. Methods 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. Results 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). Conclusion 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.
