Ileoanal pouch procedures in children.

PURPOSE: The aim of this study was to review the long-term experience with colectomy and the ileoanal pouch procedure (IAPP) in children from one hospital.

METHODS

Between 1977 and 2001, 168 children under 18 years of age underwent colectomy and IAPP. One hundred thirty-one had ulcerative colitis (UC). Twenty-six had familial colonic polyposis (FP), 9 had Hirschsprung's disease (HD), and 2 had colonic inertia. Ninety-seven had a J-pouch, 62 had a lateral pouch, and 9 had a straight pull-through (SP). The mean age was 13.9 years.

RESULTS

Complications within 2 years included pouchitis (16%), ileoanal strictures (14%), and adhesions (7%). There were no deaths. Fifty-six patients (33%) required reoperation, including 20 revisions of large pouches and 8 conversions of SP to pouches because of stool frequency. Six children (3.6%) had later pouch removal (3 had Crohn's disease). Stool frequency at 6 months was 3.8 (mean). At 6 months 5% had occasional soiling. Eighty-four percent can delay defecation over 1(1/2) hours; 82% can urinate without a bowel movement. With a mean follow-up of 11.2 years, 94.6% are functioning well.

CONCLUSIONS

Colectomy with IAPP is the preferred operation for children with UC, FP, and selected HD. The J-pouch is the preferred technique because of simplicity of construction and sparsity of complications.
