Multiple short-segment colonic duplications.

Gastrointestinal tract duplication is an uncommon congenital anomaly that rarely involves the colon. We report an unusual case of multiple short-segment duplications of the colon not previously reported in the literature. The patient had a large diverticulum-type duplication of the descending and sigmoid colon and two other tubular duplications of the transverse and ascending colon, the latter two communicating with the colon at both ends of the duplications. The symptomatic diverticulum-type of duplication was surgically treated.
