Images in medicine: Diagnosis and pre-surgical triage of transanal rectal injury using multidetector CT with water-soluble contrast enema.

Transanal rectal injuries caused by foreign body insertion, sexual abuse, or iatrogenic procedures represent a very uncommon surgical emergency. Morbidity may be further increased by patient's embarrassment and delayed presentation. Since management decisions largely depend on anatomic and severity assessment, multidetector Computed tomography with rectally administered water-soluble iodinated contrast medium is highly valuable to accurately depict traumatic rectal injuries, and to distinguish between intraperitoneal vs extraperitoneal injuries that require different surgical approaches.
