OBJECTIVE: TO determine the rate of complications of ileoanal pouch anastom
osis, 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 e
ither S-type or J-type ileoanal reservoir.
OUTCOME MEASURES: Indications, early and late complications, incidence of p
ouch excision.
RESULTS: Of the 239 patients, 228 (95.4%) were operated on for ulcerative c
olitis and 11. (4.6%) for familial polyposis coli. One patient in each grou
p was found to have a carcinoma not previously diagnosed. Twenty-eight pati
ents had poor results: in 17 (7.1%) the ileostomy was never closed or was r
e-established because of pelvic sepsis or complex fistulas, sclerosing chol
angitis or severe diarrhea; 11 (4.6%) patients required excision of the pou
ch because of anal stenosis, perirectal abscess-fistula or rectovaginal fis
tula. Three patients died - of suicide, and complications of liver transpla
ntation and HIV infection. Thus, 208 patients maintained a functioning pouc
h. The early complication rate (within 30 days of operation) was 57.7% (138
patients) and the late complication rate was 52.3% (125 patients). Pouchit
is alone did not lead to failure or pouch excision. Emptying difficulties i
n 25 patients with anal stenosis were helped in 2 by resorting to intermitt
ent 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 anastomos
is continues to tie relatively high despite increasing experience with this
technique. Overall, however, a satisfactory outcome was obtained in 87% of
patients.
