Open versus laparoscopic appendectomy in children: a comparison of complications

Although between 4% and 20% of all appendectomies in adults are performed laparoscopically, this procedure is rarely done in the pediatric age group because of the substantially more difficult technique, the expected risks and suspected higher rate of complications. In a prospective study of 500 consecutive appendectomies, we tried to assess the actual rate of complications of each operative approach. We included 362 conventional and 138 laparoscopic appendectomies, the median age of the patients was 10.8 years. The mortality was 0 in both groups. We observed 89 minor and 11 major complications. All major complications (wound infections needing re-operation under general anesthesia, intra-abdominal abscesses, ileus due to adhesions and a case of renal insufficiency because of glomerulonephritis) occurred in the conventional group (n=11, ie, 3% of 362 open appendectomies). Seventy-two minor complications were seen in the same group (20%). In the laparoscopic group, there were 17 (13%) minor complications and no severe complications. This difference was statistically significant. We conclude that in children laparoscopic appendectomy does not carry a greater risk of intra- or postoperative complications and can therefore safely be established as a standard procedure.
