Capsule endoscopy is a small pill size device used in the evaluation of diseases of the small bowel (intestine). It consists of a camera and recorder allowing complete visualization of the small bowel. The procedure is generally safe and painless lasting about 10-15 hours per examination.
The human digestive tract consists of the esophagus, stomach, small intestine and large intestine. Imaging of the small intestine is often challenging and difficult due to its length and relatively deep location along the digestive tract. Capsule endoscopy is designed to overcome this limitation allowing the entire small intestine to be visualized with reasonable sensitivity and specificity.
You will be fasted for 4-6 hours prior to the procedure and be given a small amount of liquid to cleanse the intestine before swallowing the capsule. In addition to that, an external recorder will be given to you to be worn around the waist. You can start having light meals about 4 hours after capsule ingestion. The position of the capsule can be monitored periodically (by doctor) and recording will be stopped once it is certain that the capsule has gone past the small bowel.
You will be given instructions to monitor your stool output and to keep track on when the capsule passes out completely. Patients can usually resume their normal diet unless specifically advised by health professionals.
