Capsule endoscopy is an outpatient procedure that involves visualization of the small intestine with the use of a wireless capsule equipped with a tiny camera that takes thousands of pictures for later evaluation by the gastroenterologist. The procedure, which typically takes approximately 8 hours, is able to detect abnormalities in the small bowel that the conventional endoscope and colonoscope is unable to reach.

This test is usually ordered for patients who have iron deficiency anemia, suspected or known Crohn’s disease, suspected or known Celiac disease, obscure gastrointestinal bleeding, ulcerations of the small intestine, and small bowel polyps.

During the procedure, the patient ingests a small capsule with the help of water, is made to wear a data receiver around the waist, and is then allowed to go home for the duration of the study. The patient then returns after 8 hours to return the data receiver which has wirelessly stored thousands of images taken from within the small bowel. The capsule is eventually passed in the stool. The findings are then given to the patient and recommendations are made. This procedure is painless and is simple to do.
