wireless capsule endoscope
(WY-er-les KAP-sul EN-doh-SKOPE)
A device used to look at the inside of the intestines and other parts of the digestive tract. It is a capsule that is about the size of a large pill, with a lens, a light, a camera, a radio transmitter, and a battery inside. The patient swallows the capsule and it takes pictures as it travels through the digestive tract. The pictures are sent 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 wireless capsule endoscope passes out of the body during a bowel movement. Also called capsule endoscope.
