ABSTRACT
PURPOSE: Perforated peptic ulcer (PPU) is a life-threatening complication of peptic ulcer disease. This condition is characterized by a dirty abdomen that predisposes to postoperative wound infection. Delayed primary skin closure is occasionally preferred over primary closure to reduce the risk of surgical site infection in dirty abdominal wounds. In primary skin closure, the skin is sutured immediately after surgery. Meanwhile, in delayed primary skin closure, the incision is left open, and sutured after 2-5 days. The current research aimed to compare the risk for surgical site infection, length of hospitalization, and mortality rate between primary versus delayed primary skin closure among patients who underwent surgery for PPU. METHODS: This single-blind randomized clinical trial included 120 patients who were randomly allocated into the primary and delayed primary closure groups. A research assistant who was blinded to the study examined the wounds for surgical site infection based on the 1992 Center for Disease Control criteria. The outcomes were mortality rate and duration of hospitalization. RESULTS: The delayed primary and primary closure groups did not significantly differ in terms of postsurgical wound infection occurring on the 3rd, 7th, 14th, and 30th days after surgery, mortality rate, and duration of hospitalization. CONCLUSION: In patients who underwent surgery for PPU, delayed primary closure is not recommended over primary closure due to the risk of postoperative surgical site infection.
