Congenital pouch colon: Massive redilatation of the tubularized colonic pouch after pull-through surgery.
OBJECTIVE
Children with a type I/II congenital pouch colon (CPC) malformation associated with imperforate anus usually are treated by subtotal excision of the colonic pouch, tubularization of the remaining portion, and pull-through of the tubularized colon during definitive surgery. The authors report 3 patients treated in this fashion who presented 2 to 10(1/2) years later with massive redilatation of the previously tubularized colon and enterocolitis


METHODS
There were no anal strictures or malpositioning of the pulled through bowel. Contrast enema showed massive redilatation of the colonic pouch. Near-total excision of the redilated pouch with anastomosis of normal proximal ileum/colon with the retained distal portion of the pouch was performed by the abdominal approach.


RESULTS
Anastomotic leaks occurred in 2 patients but were treated successfully. Postoperatively, the patients had relief from their abdominal symptoms and improvement in fecal continence.


CONCLUSIONS
The colonic pouch in CPC has a marked tendency to undergo redilatation, even after tubularization. The surgical procedure described here for the treatment of these patients appears to be satisfactory.
