Small-intestinal endoscopy

A small imaging capsule without cables, wires, or external connections has been developed for exploration of the small bowel. This swallowable device is propelled by peristalsis through the intestinal tract, and transmits data to a nearby receiver that captures video images on a regular basis. This technology will soon be available throughout the world, and it promises to revolutionize deep endoscopy of the small bowel. Sonde enteroscopy will be laid to rest forever. There continues to be considerable interest in the use of push enteroscopy in the investigation of obscure gastrointestinal bleeding. Physicians are beginning to rely more on intraoperative enteroscopy, because of its high degree of accuracy and its ability to provide visualization of the entire small bowel in selected patients in whom the bleeding source cannot be diagnosed, but who require blood transfusions.
