Capsule Endoscopy allows for the examination of the small intestine. By using a vitamin-pill size video capsule which has its own camera and light source, it enables the physician to examine the three portions of the small intestine: duodenum, jejunum and ileum. As the capsule travels through your body, images are sent to a data recorder which is worn around the waist.

The capsule endoscopy is used to determine the cause of recurrent or persistent symptoms such as abdominal pain, diarrhea, bleeding or anemia when other diagnostic procedures failed to determine the reason for the symptoms.

This procedure is contraindicated in patients who have a history of bowel obstruction or a difibrillator.
