Irritable Bowel Syndrome | Assessment of Small Intestinal Bowel Epithelial Gaps in Irritable Bowel Syndrome

Irritable Bowel Syndrome research study

What is the primary objective of this study?

The study aims to: 1. Determine whether the density of epithelial gaps in terminal ileum of patients with irritable bowel syndrome (IBS) is different from that in inflammatory bowel disease (IBD) patients and normal controls by confocal laser endomicroscopy (CLE). 2. Evaluate the relationship between the density of epithelial gaps and IBS subtypes, and visceral hypersensitivity.
