The role of antibiotics and probiotics in pouchitis.

Pouchitis is a non-specific inflammation of the ileal reservoir and the most common complication of proctocolectomy with ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis. Its frequency is related to the duration of the follow up, occurring in up to 50% of patients 10 years after IPAA in large series from major referral centers. Treatment of pouchitis is largely empirical and only small placebo-controlled trials have been conducted.
