Abdominal drainage after laparoscopic appendectomy in children: an endless controversy?

Background: Routine prophylactic abdominal drains after laparoscopic appendectomy for perforated appendicitis in children are still controversial. Throughout the history of surgery, potential benefits of the abdominal drains have been described. However, in recent studies, no benefits were observed and serious complications have been reported. Methods: From January 2000 to December 2013, all charts of the pediatric patients who underwent laparoscopic appendectomy in our tertiary center were revised. The data from 1736 appendectomies were analyzed. We only included those patients with perforated appendicitis treated with early appendectomy (n=192). Prophylactic drains were established according to the surgeon's preference. The sample was divided into two groups, those with drain (n=117) and those without drain (n=75). Demographics, operative findings, and postoperative outcomes were analyzed in both groups. Results: Of all patients, 121 were male and 71 were female with a mean age of 7.773.4years. There were not statistically significant differences between the groups in gender (p=0.82) and mean age (p=0.31). There were no statistically significant differences between the two groups in the rate of intra-abdominal abscess, wound infection, and bowel obstruction. However, the drainage group has been statistically associated with an increased requirement of antibiotic and analgesic medication, fasting time, operative time, and length of hospital stay. Conclusion: The prophylactic use of abdominal drainage after laparoscopic appendectomy for perforated appendicitis in children does not prevent postoperative complications and may be associated with negative outcomes. Prospective randomized studies will be necessary to verify this question.
