Fournier’s Gangrene after Open Hemorrhoidectomy without a Predisposing Factor: Report of a Case and Review of the Literature

摘要

Fournier’s gangrene (FG) is a fatal synergistic infectious disease with necrotizing fasciitis of the perineum and abdominal wall along with the scrotum and penis in men and vulva in women. An unpredictable case of FG two weeks after open hemorrhoidectomy in a previously healthy 55-year-old male is described. Full-thickness patchy skin necrosis of the perianal, perineal and scrotal region associated with rectal perforation was detected on admission. Prompt radical debridement together with aggressive fluid resuscitation and broad-spectrum antibiotic administration was initiated. Because of rectal involvement, diverting sigmoid colostomy was fashioned. The patient survived after two additional local debridements. Nevertheless, loss of sphincter function due to massive muscle destruction led to permanent colostomy. Our case together with others reported in the literature illustrates that, although rare, FG after open hemorrhoidectomy represents a life-threatening complication to otherwise healthy patients. The development of fever and urinary retention should draw the attention of the surgeon, even if the presentation is delayed. The current literature only briefly mentions the potential risk of FG after such a common surgical procedure. However, devastating complications occur more often than anticipated. This disastrous complication without predisposing factor is discussed along with a literature review.
