Evaluation of Capsule Endoscopy in Patients With Suspected Crohn's Disease (MA-51)
The aim of this study is to validate the ability of Capsule Endoscopy (CE) to accurately diagnose small bowel (SB) Crohns disease in patients with symptoms of abdominal pain and diarrhea.
The primary objective of the study is to evaluate whether Capsule Endoscopy prior to colonoscopy will improve diagnosis in patients with suspected Crohns disease when compared to standard diagnostic testing.
Study Overview
Detailed Description
Crohn's disease is a chronic, inflammatory disorder (IBD) affecting any part of the gastrointestinal tract but frequently involves the small and large bowel. Typical presenting symptoms include abdominal pain and diarrhea. Patients with this disorder may also have extraintestinal manifestations including arthritis, uveitis and aphthous stomatitis, erythema nodosum and pyoderma gangrenosum. The etiology of Crohn's disease is unknown. It affects populations around the globe and occurs at any age but it has a predilection to affect those between the ages of 15 and 35.
While about one half of patients have involvement of the ileum and large bowel, another third have disease isolated to the small bowel. Frequently, small bowel Crohn's disease can be difficult to diagnose using the traditional methods of evaluation including colonoscopy with ileoscopy and contrast radiography. Mucosal features of Crohn's disease are often subtle and difficult to identify by small bowel follow through (SBFT). The SBFT has traditionally been relied on to evaluate the small intestine for evidence of Crohn's disease but it has been shown to have a relatively low accuracy of only 30%. This has led to delays in the diagnosis of Crohn's disease with reports ranging from one to three years.
In the past few years, capsule endoscopy has sparked renewed interest in the investigation of IBD and Crohn's disease of the small bowel. A PillCam™ SB2 capsule (Given Imaging Ltd, Yoqneam, Israel) is an ingestible, disposable video camera that transmits high quality images of the small intestinal mucosa. This enables the small intestine to be readily accessible to physicians investigating for the presence of small bowel disorders which in the past was inaccessible to physicians. A number of small pilot studies demonstrated capsule endoscopy efficacy in diagnosing SB Crohn's disease. Diagnostic yields of 70% have been reported in small series of studies performed in suspected small bowel Crohn's disease.
This study is designed to determine the yield and clinical impact of Capsule Endoscopy (CE) in detecting suspected IBD and suspected Crohn's Disease of the small bowel when compared to SBFT.
