Anorectal avulsion is an exceptional rectal trauma in which the anus and sphincter no longer join the perineum and are pulled upward. As a result, they ventrally follow levator ani muscles. We present a rare case of a 29-years old patient who was admitted in a pelvic trauma context; presenting a complete complex anorectal avulsion. The treatment included a primary repair of the rectum and a diverting colostomy so as to prevent sepsis. Closure of the protective sigmoidostomy was performed seven months after the accident and the evolution was marked by an anal stenosis requiring iterative dilatations.
KeywordsAnorectal avulsion Rectal trauma Surgical management
Anorectal avulsion is an exceptional rectal trauma. In this kind of lesions, the anus and sphincter no longer join the perineum and are pulled upward. They are in addition ventrally following levator ani muscles. The management of this kind of lesions remains a matter of great debate. Early repair of the rectum, diverting colostomy, wound debridement, distal rectal wash-out are the most important procedures that help prevent sepsis. In addition, the colostomy closure can only be performed after pelvic rehabilitation in order to prevent transitory incontinence.
