Fournier's gangrene after Milligan-Morgan hemorrhoidectomy requiring subsequent abdominoperineal resection of the rectum: Report of a case

The development of Fournier's gangrene after Milligan-Morgan hemorrhoidectomy of a previously healthy 76-yearold female patient is described. After such a common surgical procedure, the patient developed full-thickness skin necrosis of the perianal region including the rectum. Immediate radical debridement was mandatory. Because of rectal involvement, a diverting sigmoid colostomy was required. The rectum had to be removed by abdominoperineal resection. This disastrous complication was completely unexpected and unpredictable after Milligan-Morgan hemorrhoidectomy because of the lack of predisposing factors.
