Congenital pouch colon and segmental dilatation of the colon: A report of two unusual cases

Abstract

This report describes two unusual cases of anorectal malformation. The first had a type III congenital pouch colon with a colovesical fistula. In the other very similar case, segmental dilatation of the colon was present along with penoscrotal hypospadias and, distally, a length of normal colon ending in a rectourethral fistula. In both patients, the appendix was short, stubby and a Y-shaped duplication of the normal colon was present just proximal to the dilated segment of colon.
