Abstract

Objective

To determine the rate of complications of ileoanal pouch anastomosis, their treatment and their influence on a successful outcome.

Design

A computerized database and chart review.

Setting

Three academic tertiary care health centres.

Patients

All 239 patients admitted for surgery between 1981 and 1994 with a diagnosis of ulcerative colitis and familial adenomatosis coli.

Interventions

Sphincter-saving total proctocolectomy and construction of either S-type or J-type ileoanal reservoir.

Outcome measures

Indications, early and late complications, incidence of pouch excision.

Results

Of the 239 patients, 228 (95.4%) were operated on for ulcerative colitis and 11 (4.6%) for familial polyposis coli. One patient in each group was found to have a carcinoma not previously diagnosed. Twenty-eight patients had poor results: in 17 (7.1%) the ileostomy was never closed or was re-established because of pelvic sepsis or complex fistulas, sclerosing cholangitis or severe diarrhea; 11 (4.6%) patients required excision of the pouch because of anal stenosis, perirectal abscess-fistula or rectovaginal fistula. Three patients died — of suicide, and complications of liver transplantation and HIV infection. Thus, 208 patients maintained a functioning pouch. The early complication rate (within 30 days of operation) was 57.7% (138 patients) and the late complication rate was 52.3% (125 patients). Pouchitis alone did not lead to failure or pouch excision. Emptying difficulties in 25 patients with anal stenosis were helped in 2 by resorting to intermittent catheterization. Patients with indeterminate colitis had a higher rate of anorectal septic complications, and all patients having Crohn’s disease after pouch construction had complicated courses.

Conclusions

The complication rate associated with ileoanal pouch anastomosis continues to be relatively high despite increasing experience with this technique. Overall, however, a satisfactory outcome was obtained in 87% of patients.
