Abdominal Drainage at Appendectomy for Complicated Appendicitis in Children: A Propensity-matched Comparative Study
Objective:
The aim of the study was to investigate the effect of abdominal drainage at appendectomy for complicated appendicitis in children.
Summary of Background Data:
Although an abdominal drain placement at appendectomy is an option for reducing or preventing postoperative infectious complication, there is controversy regarding its effect for complicated appendicitis.
Method:
The study used the data on appendectomies for complicated appendicitis in children (≤15 years old) that were operated in 2015 and registered in the National Clinical Database, a nationwide surgical database in Japan. One-to-two propensity score matching was performed to compare postoperative outcomes between patients with and without drainage at appendectomy.
Result:
The study included 1762 pediatric appendectomies for complicated appendicitis, 458 of which underwent abdominal drainage at appendectomy. In the propensity-matched analysis, the drainage group showed a significant increase in wound dehiscence [drain (−) vs drain (+); 0.3% vs 2.4%, P = 0.001], and postoperative hospital stay (median: 7 days vs 9 days, P
