Abstract

OBJECTIVE:

To develop a "Pouchitis Disease Activity Index" (PDAI) and to compare it with other diagnostic scoring systems for pouchitis.

DESIGN:

We compared patients who had an optimal outcome with those who had a poor result attributable to recurrent pouchitis after ileal pouch-anal anastomosis (IPAA) for ulcerative colitis at the Mayo Clinic.

MATERIAL AND METHODS:

We evaluated the applicability of a PDAI that quantitated clinical findings and the endoscopic and histologic features of acute inflammation in four groups of patients: (1) 10 who underwent IPAA for ulcerative colitis and had symptoms compatible with a clinical diagnosis of pouchitis, (2) 5 who underwent IPAA for ulcerative colitis and did not have pouchitis, (3) 5 who underwent IPAA for familial adenomatous polyposis and had no symptoms of pouchitis, and (4) 5 who had a Brooke ileostomy for ulcerative colitis (control group).

RESULTS:

The PDAI was significantly greater in patients with the clinical features of pouchitis than it was for patients in the other three groups. All 10 patients with pouchitis fulfilled the PDAI criteria for a diagnosis of pouchitis; in contrast, only 1 of these 10 patients met the diagnostic criteria for pouchitis by application of previously established scoring systems. No asymptomatic patient qualified for a diagnosis of pouchitis by the PDAI criteria.

CONCLUSION:

The PDAI provides simple, objective, and quantitative criteria for pouch inflammation after IPAA and is more sensitive than prior scoring systems.
