A capsule endoscopy is a test that looks at the inside of your small bowel and your large bowel using a video capsule. This is called video endoscopy (VCE).
A capsule is swallowed that contains a small disposable camera and is the size of a large pill. The camera takes thousands of pictures as it travels along your digestive tract. The camera transmits the pictures wirelessly to a data recorder that you wear on a belt around your waist.
You might have this test if your doctor needs to look closely at the inside of your small bowel. It examines the part of the bowel that other tests such as gastroscopy or colonoscopy might not always reach.
