Perineal trauma with anal avulsion: case report.

Anorectal avulsion is an exceptional rectal trauma. In this kind of lesions, the anus and the sphincter no longer join the perineum and are pulled upward. We present a case of 34-years-old patient who was admitted because of a pelvic-perineal trauma, presenting a partial anorectal avulsion, exposed femoral fracture with thigh's lacerated-contused wound. Our treatment included primary plastic of the internal anal sphincter with replanting of the rectum on the anal canal and a diverting loop sigmoid colostomy (SCS), so as to prevent sepsis. Closure of the protective SCS was performed four months after the trauma.
