Ileal pouch-anal anastomosis is performed routinely for chronic ulcerative colitis.
Dr Hahnloser and colleagues used data from a prospective database and annual standardized questionnaires.
The team of doctors assessed functional outcome, complications and quality of life after ileal pouch-anal anastomosis.
The team performed 1885 ileal pouch-anal anastomosis operations for chronic ulcerative colitis over a 20-year period.
The mean age at the time of ileal pouch-anal anastomosis was 34 years, increasing from 31 years between 1981 and 1985 to 36 years between 1996 and 2000.
The doctors reported that the overall rate of pouch success at 5, 10, 15 and 20 years was 96%, 93%, 92% and 92%, respectively.

The team found that the mean daytime stool frequency increased from 6 at 1 year to 7 at 20 years.
The doctors noted that the stool frequency also increased at night.
The incidence of frequent daytime fecal incontinence increased from 5% to 11% during the day.
The team found that the incidence of fecal incontinence increased from 12% to 21% at night.
The team observed that quality of life remained unchanged.
The doctors found that 92% of patients remained in the same employment.
The team eventually diagnosed 76 patients with indeterminate colitis, and 47 with Crohn's disease.
Dr Hahnloser's team concluded, “Ileal pouch-anal anastomosis is a reliable surgical procedure for patients requiring proctocolectomy for chronic ulcerative colitis and indeterminate colitis.”
“The clinical and functional outcomes are excellent and stable for 20 years after operation.”
