Effect of Colostomy on Treatment Outcome in Fournier Gangrene: A Prospective Comparative Study.

Abstract

Background and Aim: Value of colostomy in management of Fournier gangrene (FG) is a debatable issue. Almost all relevant studies are retrospective and included heterogeneous patients' groups. The present prospective study aimed to evaluate the role of colostomy in management of FG affecting the perianal region in 2 well-matched FG groups. Patients and Methods: The present prospective comparative study included 30 patients with FG associated with extensive involvement of the perianal region. They comprised 15 patients subjected to colostomy and other 15 patients who refused to perform the procedure. Colostomy was performed after the first debridement. Outcome parameters in the present study included time to wound healing, length of hospital stay, and inhospital mortality. Results: Comparison between the studied groups regarding the preoperative characteristics revealed no statistically significant differences. Postoperatively, patients in the colostomy group had significantly fewer number of debridements (1.3 ± 0.5 vs 2.7 ± 1.2, P < .001), shorter hospital stay (9.5 ± 3.3 vs 29.9 ± 6.2 days, P < .001), and significantly shorter time to wound healing (16.5 ± 3.9 vs 42.9 ± 6.9 days, P < .001). Also, patients in the colostomy group had significantly lower rate of wound dehiscence, wound infection, and flap ischemia. However, the difference wasn't statistically significant. Conclusions: Aggressive treatment of FG aided by colostomy after first debridement would result in better clinical outcome.
