Capsule endoscopy uses a small wireless camera to capture images of your gastrointestinal tract. The camera used for the procedure is located in a small capsule shaped like a pill.
When you swallow the capsule, the camera inside begins a journey through the gastrointestinal tract. During this time, the camera takes thousands of pictures. These images are transmitted to a recording device that you wear on your waist.
Although it can be used to view many parts of the gastrointestinal tract, capsule endoscopy is particularly useful for examining the small intestine. This is because the small intestine is difficult to access using more conventional endoscopy techniques.
