Capsule endoscopy and Crohn's disease.

Capsule endoscopy has been shown to detect small bowel inflammatory changes better than any other imaging modality. Selection criteria have been optimized to increase the yield of capsule endoscopy in patients suspected of having Crohn's disease. Capsule endoscopy allows for earlier diagnosis of Crohn's disease of the small bowel and improved diagnosis of colitis in patients where it is unclear if they suffer from Crohn's or ulcerative colitis. A test capsule is available to assess for small bowel strictures and thus avoid capsule retention. It is envisioned that the manner in which we treat Crohn's disease in the future will change, based on earlier diagnosis and treatment aimed at mucosal healing rather than symptom improvement.
