The digestive system of a person is composed of the esophagus, the stomach, the small intestine, and the large intestine. A typical upper gastro-intestinal endoscope can be inserted only up to the distal part of the duodenum, and colonoscopy can observe up to the distal ileum through the ileocecal valve. In addition, various radiotherapy diagnosis including small intestine barium angiography and CT also have very low diagnostic rates for small intestine diseases.

However, MiroCam® Capsule Endoscope is a small capsule with diameter of 10.8mm and length of 24.5mm, and contains a small camera, a flash, and a transmission device. It transmits and examines the pictures taken while passing through the digestive tract along with bowel movement. By doing so, it is possible to carry out examinations not only for the small intestine, which is hard to observe, but also for the digestive system.

It can also film images of the large intestine based on the capsule life of more than 11 hours. There is no particular inconvenience and it can be safely performed since the capsule endoscopy is done during the normal day.
