For capsule endoscopy, the intestines are cleared first of residual food and the bacterial debris with the use of laxatives and/or purges very similar to the laxatives and purges used before colonoscopy. A large capsule-larger than the largest pill-is swallowed by the patient. The capsule contains one or two video chips (cameras),as a light bulb, a battery, and a radio transmitter. As that the capsule travels through the esophagus, stomach, and small intestine, it takes the photographs rapidly. These photographs are transmitted by the radio transmitter to a small receiver that which is wornon the waist of the patient who is undergoing for the capsule endoscopy.At the end of the procedure, approximately 8 hours later, the photographs are downloaded from the receiver into a computer, and the images are reviewed by a physician. The capsule is passed by the patient into the toilet and then it is flushed away. There is no need to retrieve the capsule
Capsule endoscopy has also been approved to evaluate the muscular tube that connects to mouth and stomach (esophagus) to look for abnormal, enlarged veins (varices). It is used rarely because the experience with it is limited and the traditional upper endoscopy is widely available.
