Endoscopy
Video Capsule Endoscopy
In video capsule endoscopy (wireless video endoscopy), patients swallow a disposable capsule containing a camera that transmits images to an external recorder; the capsule does not need to be retrieved. This noninvasive technology provides diagnostic imaging of the small bowel that is otherwise difficult to obtain by conventional endoscopies. This procedure is particularly useful in patients with occult gastrointestinal bleeding and for detection of mucosal abnormalities. Capsule endoscopy is more difficult in the colon and, therefore, is not commonly used as a modality for Colorectal Cancer Screening .
