Pouchitis: diagnosis and management.

Area of Science:

• Gastroenterology
• Surgical Complications
• Inflammatory Bowel Disease

Background:

• Pouchitis, inflammation of the ileal pouch, is the most frequent complication following ileal pouch-anal anastomosis (IPAA).
• It disproportionately affects patients with ulcerative colitis and presents in idiopathic or secondary forms.
• Chronic antibiotic-dependent pouchitis (CADP), chronic antibiotic-resistant pouchitis (CARP), and Crohn's disease of the pouch represent particularly challenging therapeutic scenarios.

Purpose of the Study:

• To review current diagnostic and therapeutic strategies for idiopathic pouchitis and Crohn's disease of the pouch.
• To highlight emerging treatment trends for complex pouchitis cases.

Main Methods:

• Review of recent literature on pouchitis diagnosis and treatment.
• Focus on novel therapeutic agents and approaches.

Main Results:

• Biologic agents like vedolizumab and ustekinumab demonstrate positive outcomes in CADP, CARP, and Crohn's disease of the pouch.
• Fecal microbiota transplantation shows encouraging preliminary results for chronic pouchitis treatment.

Conclusions:

• Emerging treatments offer new hope for refractory pouchitis.
• Larger prospective studies are essential to validate efficacy, safety, and identify response predictors across pouchitis subtypes.
