Anorectal avulsion-an unusual anorectal trauma

Abstract

Anorectal avulsion is a rare trauma. In this type of lesion, the anus and the sphincter complex are pulled up by a tremendous compression of the pelvic floor. Frequently, this trauma is associated with other injured organs, like pelvic bones or urethra. We report a case of a young man who was admitted with a total anorectal avulsion associated with a pelvic fracture. A multidisciplinary treatment included external fixation of the broken pelvis, suprapubic cystostomy, sigmoid loop colostomy and reimplanting the anal complex in the original position with appropriate drainage. Anorectal injuries are uncommon and represent about less than 10% of rectal trauma, but anorectal avulsion is extremely rare. These cases often require a quick decision making and multidisciplinary approaches to reduce the possibilities of morbidity and mortality.
