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

Congenital Segmental Dilatation of Ascending Colon with Distal Microcolon: A Diagnostic Dilemma

A 5-day-old male presented with bilious vomiting, a grossly distended abdomen, and passage of a small amount of stool. The anal opening was at a normal position. X-ray abdomen showed a large bowel loop with a single air-fluid level occupying more than half of the abdominal width. On laparotomy, the ascending colon was dilated to form a pouch-like structure, and the ileum and appendix were opening into it. Colon distal to pouch was present as microcolon. Histopathology of the dilated segment was suggestive of congenital segmental dilatation (CSD). In CSD, the distal bowel is of normal caliber. This is a rare case of CSD of ascending colon with distal microcolon.

Congenital pouch colon with ileovesical and colovesical fistulae: A new variant

We report a case of persistent cloaca and type I congenital pouch colon associated with ileovesical and colovesical fistulae. Such a malformation has not been reported so far.
