Assessment of Outcomes After Limberg Flap Reconstruction for Scrotal Defects in Patients With Fournier's Gangrene

Background. Fournier's gangrene (FG) is a rarely encountered necrotizing fasciitis principally affecting skin and subcutaneous tissues of the genital region, perineum, and abdominal wall. The overall incidence of FG is 1.6 cases per 100 000 per year; the incidence in males is higher. Management techniques described in the literature have both advantages and disadvantages, and there is no gold standard treatment technique. Objective. This study evaluated whether the Limberg flap can be used reliably in scrotal defects with fewer complications than are seen with traditional techniques. The results of unilateral or bilateral Limberg flaps for scrotal reconstruction after FG were assessed. Materials and Methods. This retrospective, single-center study analyzed records from 29 male patients with scrotal defects after multiple debridements who were treated from January 2013 to January 2018. Twenty-one patients (72.4%) with hemiscrotal defects and 8 patients (27.6%) with defects involving greater than 50% of the scrotal surface were included in this study. Demographic data that were analyzed included smoking history, comorbid conditions, time of surgery, and time of follow-up. Flap dimensions were measured. Patients were evaluated in terms of flap viability and postoperative complications. Results. Mean age was 64 years (range, 47-80 years). The mean follow-up period was 16 months (range, 12-26 months). Dehiscence with seroma were detected in 4 patients (13.7%) on postoperative days 4 and 5. The average size of the flaps was 11 cm x 15 cm. Seroma and dehiscence were encountered in 4 patients (13.7%) during postoperative follow-ups. No postoperative infection was observed in any patient, and no partial or total flap loss was reported. Conclusions. These results suggest that use of the Limberg flap technique for scrotal reconstruction following FG has the important benefits of being easily harvested while providing tension-free repair and acceptable cosmetic results.
