Delayed primary wound closure using skin tapes for advanced appendicitis in children. A prospective, controlled study.

In a 3-year period, 63 consecutive patients with advanced perforated (n=53) and gangrenous (n=10) appendicitis were allocated to undergo either immediate wound closure or delayed primary wound closure after emergency appendectomy. The incidence of wound infection between delayed primary wound closure and immediate wound closure was similar (24.0% and 21.1%, respectively). The duration for complete healing of infected wounds was slightly shorter in the group undergoing delayed primary wound closure (mean +/- SD, 24.3 +/- 9.2 days) than in the group undergoing immediate wound closure (mean +/- SD, 32.6 +/- 16.5 days), but the difference was not significant. However, healing of noninfected wounds was significantly prolonged in the group undergoing delayed primary wound closure (mean +/- SD, 19.3 +/- 10.1 days) compared with the group undergoing immediate wound closure (mean +/- SD, 7.0 +/- 0 days). The latter had been shown to associate with more nonseptic wound complications and therefore required longer rehabilitation. Our study showed that delayed primary closure did not offer additional advantage over immediate closure in the treatment of wounds associated with advanced appendicitis in children.
