Pediatric anorectal impalement with bladder rupture: case report and review of the literature.

Rectal impalement involves foreign body trauma to the anus or rectum resulting in intra- or extraperitoneal rupture. Evaluation of suspected rectal impalement injury involves careful history and physical examination. Ruling out rectal perforation in patients with reported impalement is critical even if there is no evidence of trauma to the perineum. There are few reports on pediatric impalement and only 1 reported case of pediatric rectal impalement with bladder rupture. We report a rectal impalement with extraperitoneal bladder injury in a 12-year-old boy and review the literature on treatment of these injuries.
