hospital care image (big) A capsule containing a tiny camera that takes pictures of the lining of the intestines is one tool doctors have to help detect polyps, cancer, and sources of bleeding in the small intestine that current tests cannot always find. The procedure is called capsule endoscopy.

You swallow a small capsule that contains a camera. As the capsule passes through the small intestine, the camera snaps pictures 4 times per second. The capsule is eventually excreted naturally, without you feeling anything unusual.

As the capsule moves through the GI tract, it sends signals to a data recorder worn on a belt around your waist. You wear the recorder for about 8 hours as you go about your daily activities. The images stored on the data recorder can be downloaded to a computer and viewed by a physician.

Technology will bring improvements. Newer forms of the capsule may allow for controlling movement, biopsies, or dispensing medication. Capsule endoscopy is a peek into exciting medical innovations that may keep us healthy without certain hassles of endoscopies or colonoscopies.
