Posterior Detachment of the Anorectum Following Blunt Trauma to the Perineum

Abstract

To the best of our knowledge, there have been few reports in the literature about perineal injury without an associated pelvic fracture. In this report, we are going to discuss the mechanism, management, and outcome of two cases of perineal injury associated with car accidents. The two cases, one male and one female, presented with sustained isolated soft tissue injuries to the perineum. Both cases revealed a separated anorectum from the coccyx and sacrum without detectable damage to the lumen or surrounding sphincter. Pelvis fracture was not present in either case nor did the urinary bladder or urethra show signs of injury. A defunctioning (temporary) colostomy medical innervation was done to both and the perineal wound was left to heal. At last, both patients were satisfied with the final outcome.
