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.

Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
