Long-term follow-up of a randomized clinical trial of open versus laparoscopic appendicectomy

Abstract

Background: The aim of this study was to assess long-term outcome following open versus laparoscopic appendicectomy.

Methods: A total of 105 patients with suspected acute appendicitis were randomized to LA (51) or OA (54) between 1997 and 1999 at one hospital. Perioperative factors and follow-up data from the outpatient clinic were recorded. Information about symptoms and overall satisfaction was obtained by telephone interview. In addition, appendicectomy data for 2008 were analysed retrospectively for comparison in a contemporary setting.

Results: Data from 52 patients who had OA and 47 who had LA were analysed. OA was performed mostly by trainees, but LA was more likely to be undertaken by a consultant. The open procedure was quicker than the laparoscopic operation in the trial period (median 38 versus 65 min respectively; P < 0.001), but the difference was only 10 min in 2008. The OA group returned to work later than the LA group (median 13 versus 8 days; P = 0.013) and had more complications (22 versus 6; P = 0.014). Only one patient (OA) had a reoperation, owing to abdominal adhesions. Among 76 patients available for telephone interview, satisfaction scores were marginally higher for LA than OA.

Conclusion: LA has some advantages compared with an open approach.
