Abstract

Purpose: We aimed to identify predictive factors for the development of chronic pouchitis after ileal pouch-anal anastomosis in patients with ulcerative colitis. Methods: Three hundred eighty-seven patients who underwent ileal pouch-anal anastomosis for diagnosis of ulcerative colitis from January 2002 to March 2019 were included in this retrospective analysis. Results: Of 115 patients with pouchitis, 40 patients exhibited acute pouchitis, and 75 patients exhibited chronic pouchitis. Of 75 patients with chronic pouchitis, 11 patients were diagnosed with chronic antibiotic-refractory pouchitis. Multivariate analysis revealed that early pouchitis onset and modified Pouchitis Disease Activity Index score ≥ 7 were independent predictive factors for chronic pouchitis (p = 0.0004 and p = 0.029, respectively). Mean onset of pouchitis after intestinal continuity was significantly earlier in patients with chronic pouchitis than in patients with acute pouchitis (acute pouchitis vs. chronic pouchitis: 3.72 ± 2.98 years vs. 1.85 ± 2.40 years, p < 0.0001). Total modified Pouchitis Disease Activity Index score was significantly higher in patients with chronic pouchitis than in patients with acute pouchitis (acute pouchitis vs. chronic pouchitis: 5.9 ± 1.2 vs. 6.9 ± 1.6, p = 0.0020). Conclusion: Patients with ulcerative colitis were more likely to develop chronic pouchitis if they exhibited early onset or severe disease activity at onset. Evaluation of both factors can aid in early treatment decisions to alleviate chronic pouchitis.
