Conventional versus laparoscopic surgery for acute appendicitis

Abstract

A total of 155 consecutive patients with suspected acute appendicitis were studied to compare laparoscopic and conventional operations. Patients were not randomized: laparoscopy was performed when a suitably trained surgeon and laparoscopic instruments were available. Laparoscopic appendicectomy was attempted in 51 patients and was successful in 46 (90 per cent); all conversions to open operation were because of marked inflammatory adhesions around the appendix. There were no intraoperative complications. Reintroduction of normal diet and discharge from hospital occurred earlier after laparoscopic than open surgery (P < 0.05). The requirement for analgesia after successful laparoscopic surgery was less than that after conventional appendicectomy, but the difference was not significant. The incidence of wound infection was reduced after the laparoscopic procedure (P = 0.06). It is concluded that laparoscopic appendicectomy is practical and may have advantages over conventional operation, although a randomized study is necessary.
