Abstract

Purpose

We conducted a meta-analysis to evaluate and compare the outcomes of laparoscopic and open surgery for the treatment of patients with acute appendicitis.

Methods

We searched MEDLINE, EMBASE, Science Citation Index, and the Cochrane Controlled Trial Register for relevant papers published between January 1990 and February 2012. We analyzed 22 outcomes of laparoscopic and open surgery for acute appendicitis.

Results

We identified 39 papers reporting results from randomized controlled trials that compared laparoscopic surgery with open surgery for acute appendicitis. Our meta-analysis included 5,896 patients with acute appendicitis; 2,847 had undergone laparoscopic surgery, and 3,049 had undergone open surgery. Compared with open surgery, laparoscopic surgery was associated with longer operative time (by 13.12 min). However, compared with open surgery, laparoscopic surgery for acute appendicitis was associated with earlier resumption of liquid and solid intake; shorter duration of postoperative hospital stay; a reduction in dose numbers of parenteral and oral analgesics; earlier return to normal activity, work, and normal life; decreased occurrence of wound infection; a better cosmesis; and similar hospital charges.

Conclusions

Laparoscopic surgery may now be the standard treatment for acute appendicitis.
