The primary indication has been for the diagnosis of the site of obscure GI bleeding in adults. In addition, the capsule is being used increasingly for the diagnosis of small bowel tumors, vascular malformations, NSAID related small bowel injury, suspected Crohn’s disease, evaluation for iron deficiency anemia, suspected celiac sprue, and polyposis syndrome.
The capsule takes two images per second, which are transmitted as JPEG files to the recorder which acquires up to 55,000 images over approximately eight hours .The images are then uploaded onto a computer and are viewed in a movie sequence.

Capsule Endoscopy heralds an important step in the diagnosis of disorders of the small bowel. Not only it is valuable in the previously difficult-to-detect lesions in the small bowel, but also it helps detecting them at an earlier stage thereby enabling treatment before the development of complications. In all, the capsule endoscopy promises to be an invaluable tool in the diagnosis and evaluation of disorders of the small intestine.
