Video capsule endoscopy is a procedure that allows a doctor to examine your small intestine for sources of bleeding. It may be especially helpful for diagnosing Crohn's disease . How is it done? For this procedure, you swallow a capsule that is less than an inch long (about 23 millimeters ). A technician attaches sensors to your chest and connects them to a data recorder that you wear on a belt around your waist. The capsule contains a tiny video camera. As the capsule travels through your gastrointestinal tract, the camera takes pictures and sends them to the data recorder.
