Capsule Endoscopy

A pill-like capsule with a camera inside is swallowed, and over the next 8 hours takes thousands of pictures, which are transmitted wirelessly to a recording device that is worn around the waist like a fanny pack. After returning the fanny pack recording device to the office, these 8 hours of images are then uploaded to the computer and reviewed by the physician. This is used to examine the middle part of the small intestine that cannot be examined through an EGD or colonoscopy. It is typically used to look for obscure sources of bleeding or to look for Crohn's disease or other abnormalities of the small intestine. To exclude the possibility of a stricture behind which the capsule could get stuck, a CT enterography or small bowel follow through is always performed before a capsule endoscopy. The capsule is passed in the stool and flushed down the toilet (they are not reused).
