A Capsule endoscopy examines parts of the gastrointestinal tract that cannot be seen with other types of endoscopy.

When is Capsule endoscopy performed?

A Capsule endoscopy is usually performed when disease is suspected in the small intestine, and can sometimes diagnose sources of unexplained bleeding or causes of abdominal pain such as Crohn’s disease, or peptic ulcers.

How does the procedure work?

The capsule is the size and shape of a pill and contains a tiny camera. After a patient swallows the capsule, it takes pictures of the inside of the gastrointestinal tract. A capsule endoscopy transfers the captured images wirelessly to an external receiver worn by the patient, using one of appropriate frequency bands. The collected images are then transferred to a computer for diagnosis, review and display.

How long does it take?

Once you have swallowed the capsule, you can continue with your daily activities, and may even be able to go to work (restrictions can be discussed with your doctor). 2 hours after swallowing the capsule, you can drink clear liquids, and 4 hours later you can eat something light. The entire procedure will be complete after 8 hours (or when the capsule comes out after a bowel movement-whichever comes first). You can then remove the equipment from your body and flush the camera capsule down the toilet.
