 Video capsule endoscopy (VCE) is a major advance in visualization of the small intestine and has been widely used against small intestinal involvement mainly in the United States and Europe, since 2000. A new capsule endoscope developed by Olympus Medical Systems provides upgraded resolution, depth of field, and brightness of the image, by improving the optical system, combined with the new function of adjusting the level of lighting automatically, according to the surrounding brightness and the original handy real-time viewer display. Clinical trial using this capsule demonstrated a significantly higher diagnostic yield compared with barium contrast radiography of the small bowel, especially for vascular involvement. The real-time viewer could be useful for detecting gastric transit abnormality as well as for increasing the likelihood of a complete small-bowel examination with metoclopramide administration. Together with balloon-equipped enteroscopy, VCE is a new device which contributes to the diagnosis and the treatment of small bowel lesions.
