Partially avulsed anus in blunt traumatic perineal laceration: Case report.

Blunt civilian perineal laceration with anorectal avulsion is rare and usually associated with severe pelvic trauma. The principles of management of these injuries consist of repair of the laceration (primarily or secondary), diversion of fecal stream, and presacral drainage of the wound. Unnecessary diversion of fecal stream may add complications and increases patient's morbidity. We report a case of severe blunt traumatic perineal laceration associated with partially avulsed anus which was managed without colostomy. The wound healed completely with preserved anal sphincter function. To our knowledge, no similar cases of anal avulsion were treated without diversion of the fecal stream in the English literature.
