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.

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?
Irritable Bowel Syndrome
Inflammatory Bowel Disease
Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.
Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
Irritable bowel syndromePatients admitted to outpatient department with symptoms meeting Rome III criteria of irritable bowel syndrome.
InflammationPatients with long standing history or short onset of inflammatory bowel disease.
Normal controlsAsymptomatic individuals admitted for health surveillance or patients for follow up after polypectomy.
