Laparoscopic Appendectomy for Acute Appendicitis versus Chronic Appendicitis

Abstract

ABSTRACTBackground: The advantage or disadvantage of laparoscopic appendectomy for acute appendicitis remains unclear. Patients and Methods: Data were collected prospectively from 129 consecutive patients with appendicitis between June 2008 and December 2009. The clinical outcomes of acute appendicitis after laparoscopic and open operation were compared. Furthermore, the outcomes of laparoscopic procedure for acute and chronic appendicitis were compared. Results: The length of hospitalization and incidence of intra-abdominal abscess were significantly decreased in patients with laparoscopic group after operation as compared to open operation. The mean operation time, the time of first anal exsufflation, and oral intake after operation were longer for acute appendicitis patients than for chronic appendicitis in laparoscopic group. The incidence of postoperative intestinal obstruction in patients with acute appendicitis was higher after laparoscopic surgery than after open procedure. Conclusions: Laparoscopic appendectomy for acute appendicitis is feasible and safe. However, laparoscopic appendectomy for acute appendicitis might cause more postoperative complications including intra-abdominal abscess and small intestinal obstruction compared to laparoscopic appendectomy for chronic appendicitis. These complications could potentially be avoided by improving techniques in operation.
