Background

Although pouchitis is the most common complication after ileal pouch-anal anastomosis (ileal pouch-anal anastomosis) for ulcerative colitis (ulcerative colitis), the influence of diet on pouchitis is poorly understood.

Purpose

We evaluated dietary intake in the period after the final stage of ileal pouch-anal anastomosis for ulcerative colitis and Body Mass Index (BMI) to identify potential associations with pouchitis.

Methods

We used the Dietary Screener Questionnaire (Dietary Screener Questionnaire) to assess dietary intake among patients in a prospective cohort enrolled within 2 weeks of the final stage of ileal pouch-anal anastomosis for ulcerative colitis.

n = 89 patients

Results

higher presurgery BMI, worse pouchitis risk

29.2BMI

Pouchitis

24.8BMI

No pouchitis

More results

Among 89 patients, there was no significant difference in individual fiber intake when comparing those who developed pouchitis and those who did not.

“

Conclusion · 1 of 2

In a prospective cohort, we identified no association between dietary intake and development of pouchitis within the first year after ileal pouch-anal anastomosis.

Conclusion · 2 of 2

However, elevated BMI may represent a unique target for intervention to prevent pouchitis occurrence.
