Wireless Capsule Endoscopy
Wireless Capsule Endoscopy
Wireless capsule endoscopy is a procedure that uses a swallowed video capsule to take photographs of the inside of the esophagus, stomach and small intestines. The capsule has one or two video chips that wirelessly transmit thousands of pictures to a wireless recorder you wear around your waist. At the end of the procedure, your doctor downloads the pictures into a computer for review. Your body will expel the capsule, which can be flushed away without need for retrieval.

This procedure is typically done to determine the cause of gastrointestinal bleeding or iron deficiency anemia of unclear etiology, aid in the diagnosis of Inflammatory Bowel Disease (IBD) and evaluation for cancer or celiac disease.
