Small Bowel Capsule
Endoscopy involves examining the inside of the body, usually with a lighted, flexible instrument called an endoscope. With capsule endoscopy, a pill-sized capsule is used instead of an endoscope tube. The capsule contains a tiny video camera, a light, a battery and transmitter. Images from the camera are transmitted to sensors attached to the patient’s body and recorded digitally on a small device worn around the waist. Capsule endoscopy is a way to record images of the digestive tract, including the small bowel (small intestine), usually to detect the cause of unexplained bleeding, abdominal pain and other gastrointestinal (stomach and intestinal) problems. The capsule is swallowed with a drink of water. It takes around eight hours for the capsule to move through the small intestine. After this time the digital recorder is removed and the information downloaded to computer for examination. Capsule endoscopy is useful for examining parts of the gastrointestinal tract that cannot be seen with other types of endoscopy.
