A female patient with congenital pouch colon (CPC): a case report.

Congenital short colon, more commonly known as pouch colon, is a rare anomaly that can be encountered with anorectal malformations (ARM). The colon is shorter than normal and the distal end is dilated like a pouch. We report the case of a newborn with a Type 2 pouch colon. A female newborn was brought to our clinic with a diagnosis of cloaca anomaly. Her physical examination revealed a single canal introitus and flat perineum. In the abdominal x-ray taken in the upright position, a prominent air sac was noticed at the left side. A laparotomy was performed and exploration demonstrated that the colon was like a pouch. The pouch terminated in the upper part of the vagina with a wide canal. A genitogram displayed the presence of double uteri and double vaginas. One month after the operation we performed a cystoscopy, which showed the urethral meatus to be more proximal than normal (female type hypospadias). When the patient was 8 months old she was re-operated and anterior-abdomino-posterior sagittal anorectoplasty plus tube coloplasty were performed. She is now 4 years old and has a stool discharge of 2-3 times a day. Her physical and psychosocial development is in concordance with her age. Congenital pouch colon is a very rare anomaly, which has to be considered especially during the clinical evaluation of children with cloacal malformations and high type anorectal anomalies.
