A Prospective Analysis of Clinical Variables, Serologic Factors, and Outcome of Ileal Pouch-Anal Anastomosis in Patients With Backwash Ileitis

Abstract

There was a significantly higher incidence of pancolitis, primary sclerosing cholangitis, and high-level perinuclear anti-neutrophil cytoplasmic antibody expression in backwash ileitis-positive patients than in backwash ileitis-negative patients. The incidence of acute pouchitis, chronic pouchitis, and de novo Crohn's disease after ileal pouch-anal anastomosis does not differ significantly between backwash ileitis-positive and backwash ileitis-negative patients.
