Definition
By Mayo Clinic staffCapsule endoscopy is a procedure that uses a tiny wireless camera to take pictures of your digestive tract. The camera sits inside a vitamin-sized capsule that you swallow. As the capsule travels through your digestive tract, the camera takes thousands of pictures that are transmitted to a recorder you wear on a belt around your waist or over your shoulder.
Capsule endoscopy helps doctors see inside your small intestine — an area that isn't easily reached with conventional endoscopy. Capsule endoscopy can be used by adults and by children who can swallow the capsule. The procedure is usually started in a doctor's office.
