BACKGROUND: It is still a matter of debate whether delayed primary closure (DPC) of contaminated abdominal incisions reduces surgical site infections compared with a primary closure (PC). The aim of this study was to determine the optimal method of wound closure for patients with perforated appendicitis. METHODS: A total of 70 patients with perforated appendicitis were included. They were randomized to have their surgical incisions (skin and subcutaneous tissue) either PC or left open with Betadine-soaked gauze packing for DPC on the fifth postoperative day or later if the wound conditions were inappropriate for closure. A wound was considered infected if pus discharged from the incision site. The main outcome measures were the incidence of wound infection and the length of hospital stay (LOS). RESULTS: In the entire series, wound infection developed after incision closure in 21.4% of the patients. The PC group had a higher incidence of wound infection (38.9% vs. 2.9%, p<0.001) and longer LOS (8.4 days vs. 6.3 days, p=0.038). CONCLUSION: Delayed primary closure is the optimal management strategy for perforated appendicitis wounds. It significantly reduces the wound infection rate and length of stay.
