WCE is a noninvasive diagnostic technique that visualizes the entire small intestine and identifies lesions in parts of the small bowel not reached by traditional endoscopy. Although further studies are needed to define the exact role of WCE for diagnosing and managing small bowel tumors, its sensitivity has been shown to be superior to PE and small bowel follow-through in regard to diagnosing patients who have obscure GI bleeding, the most common indication for capsule endoscopy in the authors' series of patients with documented small bowel tumors. As more material is published, capsule endoscopy likely will be confirmed to be the diagnostic procedure of choice in patients with suspected small bowel tumors.
