- capsule endoscopy
- listen (KAP-sul en-DOS-koh-pee)
- A procedure used to look at the inside of the intestines and other parts of the digestive tract. The patient swallows a capsule about the size of a large pill. The capsule contains a tiny wireless camera that travels through the digestive tract. It takes pictures of the inside of the digestive tract and sends them to a small recorder that is worn on the patient’s waist or shoulder. The pictures are then viewed on a computer by the doctor to check for signs of disease. The capsule passes out of the body during a bowel movement.
