Video capsule endoscopy is not a painful procedure because the person swallows a pill with a tiny video camera in it that takes pictures as it moves through the gastrointestinal system. The pill is approximately 1 inch in length, which is excreted in the stool in about 2 to 3 days, relates WebMD.
In order to take the pictures, sensors are placed on the chest and these are attached to a data recorder. There are two different types of tests that use this procedure, which are a small bowel capsule endoscopy and a esophageal capsule endoscopy. The esophageal procedure takes about 20 minutes, while small bowel capsule endoscopy takes 8 hours to complete. For this procedure, a person can go home after the sensors and data recorder are attached, reports the American Gastroenterological Association. The connecting wires are worn around the waist. After 8 hours, the person returns to where the procedure was performed to return the devices.
The main applications for these procedures can include conditions like acid reflux, diarrhea, Crohn's disease, bowel disorders and tumors, Besides this procedure being painless and non-invasive, other benefits are that a person does not have to stay at a hospital for this procedure, and it is a good option for detecting a bleeding source in the intestinal region, explains WebMD.
