title: Intraabdominal abscess following open and laparoscopic appendectomy in the pediatric population.
abstract: BACKGROUND
  Studies comparing intraabdominal abscess (IAA) rates following laparoscopic appendectomy (LA) and open appendectomy (OA) have shown conflicting results.
  
  
  METHODS
  The charts of 324 children undergoing appendectomy were reviewed retrospectively to examine the incidence of IAA.
  
  
  RESULTS
  Of the 324 appendectomies, 204 (63.0%) were completed laparoscopically and 119 (36.7%) were performed open. The conversion rate was 0.2% (1/324). Of the 15 (4.6%) IAAs, 7 occurred in the LA group (3.4%) and 8 occurred in the OA group (6.7%) [p = not significant (NS)]. The incidence of IAA for perforated appendicitis for LA was 15% (7/46) and that for OA was 10% (7/70) (p = NS).
  
  
  CONCLUSIONS
  This study demonstrates no statistically significant difference in the rate of IAA among children following LA and OA. LA can be performed for perforated appendicitis without increasing the risk of IAA.
