Laparoscopic versus open appendicectomy: a prospective evaluation

A prospective evaluation of laparoscopic surgery for acute appendicitis over a 6-month period is reported. Sixty-five patients with signs and symptoms of appendicitis necessitating surgery were assigned to open (n = 36) or laparoscopic (n = 29) appendicectomy. Thirty-seven patients were female (22 open) and 28 were male (14 open). The median age was 24 (range 14–64) years for open appendicectomy and 18 (range 14–60) years for the laparoscopic procedure. The mean postoperative stay for open operation was 4.8 (range 1–21) days and for the laparoscopic route 2.2 (range 1–11) days (P < 0.05). Inflammation was confirmed histologically in 72 per cent of the open cases and in 74 per cent of the laparoscopic cases (P not significant). The wound infection rate was 11 per cent (n = 4 ) for open and 4 per cent (n = 1) for laparoscopic appendicectomy (P < 0.05). The median anaesthesia time was 52 (range 15–90) min for open appendicectomy and 48 (range 20–120) min for laparoscopic surgery (P not significant). After open appendicectomy patients had a median of 5 (range 2–12) intramuscular injections of analgesia compared with a median of 1 (range 0–5) in the laparoscopic group (P < 0.05). Two laparoscopic operations were converted to an open procedure. The results suggest that emergency laparoscopic appendicectoiny should be explored further as an alternative to open surgeŕy for acute appendicitis.
