This was a 4 year old female with a past history of duodenal atresia, omphalocele, atrial septal defect and ventricular septal defect. These were repaired early in life. At the time of the omphalocele repair, a duplicated colon was noted. The patient stools out of her vagina and her rectum, and now presents for definitive surgical correction.
Clinical Physical Exam:
Stool was noted in the vagina, as well as in the rectum.
Clinical Differential Diagnosis:
Duplicated colon, partial versus complete.
A barium enema was performed preoperatively to define the anatomy of the duplicated colon, and it showed complete colonic duplication. A Meckel scan was performed preoperatively (not provided) to rule out ectopic gastric mucosa in the colonic duplication, and it was negative.

Imaging Differential Diagnosis:
Duplicated colon, complete.
An abdominal incision was made and the duplicated colon was exposed. The duplicated colon, which emptied into the vagina, was anastomosed to the normal colon at the level of the sigmoid colon.
Colonic Duplication (Total)
Follow-up and Prognosis:
The patient had an uncomplicated post-operative course. A postoperative enema showed a satisfactory post operative result. When injecting the rectum with barium there was simultaneously filling of both colonic lumens.
