Investigation of the small bowel in gastrointestinal bleeding--enteroscopy and capsule endoscopy.

The last frontier in luminal endoscopy has been conquered. Bleeding lesions in the small intestine can present a frustrating clinical problem, but recent advances have made investigating the small bowel easier and less invasive. Capsule endoscopy and double balloon enteroscopy are two new technologies that promise to lower the barrier to evaluation of the entire small intestine. Recent studies show that capsule endoscopy improves outcomes in patients who have OGIB. Although outcome studies regarding double balloon enteroscopy have not been performed, the opportunity to treat lesions throughout the small bowel without resorting to surgery is a tremendous advance. These improvements suggest that the corner may have been turned in the diagnosis and management of small bowel bleeding. Perhaps to the next generation of gastroenterologists, small bowel bleeding will not be obscure.
