Early appendectomy versus an interval appendectomy for appendiceal abscess in children.

Abstract

We retrospectively compared the results of an early appendectomy and an interval appendectomy at a later date after initial conservative treatment in children demonstrating perforated appendicitis with a localized abscess. The preoperative conditions were similar for both groups. The early group (n = 8) showed a statistically significant longer operation time and a greater but not significant blood loss were noted while a larger number of postoperative complications were also observed. On the other hand, in the late operation group (n = 6) initial conservative management including triple antibiotic therapy proved successful without the need to drain the abscess, and thus the interval appendectomy was safely completed without any complications. There were no significant differences between the two groups with respect to length of hospital stay or medical costs. Based on these findings, we thus recommend that initial conservative treatment followed by an interval appendectomy about three months later is a useful strategy for the treatment of appendiceal abscesses in children. However, whether or not an interval appendectomy is appropriate in all patients whose inflammation is suppressed with antibiotics still needs to be clarified.
