ABSTRACT
BACKGROUND:
Structural and inflammatory adverse sequelae are common after restorative proctocolectomy and IPAA. On rare occasions, neoplasia can occur in patients with ileal pouches. Pouchoscopy plays a key role in the diagnosis, differential diagnosis, disease monitoring, assessment of treatment response, surveillance, and delivery of therapy.OBJECTIVE:
A systematic review of the literature was performed, and principles and techniques of pouchoscopy were described. DATA SOURCES PubMed, Google Scholar, and Cochrane databases. STUDY SELECTION Relevant articles on endoscopy in ileal pouches published between January 2000 and May 2023 were included based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. INTERVENTION Diagnostic, surveillance, and therapeutic endoscopy in ileal pouch disorders were included. MAIN OUTCOMEMEASURES:
Accurate characterization of the ileal pouch in healthy or diseased states.RESULTS:
The main anatomic structures of a J- or S-pouch are the stoma closure site, prepouch ileum, inlet, tip of the "J," pouch body, anastomosis, cuff, and anal transition zone. Each anatomic location can be prone to the development of structural, inflammatory, or neoplastic disorders. For example, ulcers and strictures are common at the stoma closure site, inlet, and anastomosis. Leaks are commonly detected at the tip of the "J" and anastomosis. Characterization of the anastomotic distribution of inflammation is critical for the differential diagnosis of subtypes of pouchitis and other inflammatory disorders of the pouch. Neoplastic lesions, albeit rare, mainly occur at the cuff, anal transition zone, or anastomosis.LIMITATIONS:
This is a qualitative, not quantitative, review of mainly case series.CONCLUSIONS:
Most structural, inflammatory, and neoplastic disorders can be reliably diagnosed with a careful pouchoscopy. The endoscopist and other clinicians taking care of pouch patients should be familiar with the anatomy of the ileal pouch and be able to recognize common abnormalities. See video from symposium.
