Capsule endoscopy is a non-invasive diagnostic procedure used to evaluate the small intestine for a range of conditions, including gastrointestinal bleeding, Crohn’s disease, and tumors. During the procedure, the patient swallows a small, disposable capsule containing a camera, battery, and transmitter. The capsule travels through the digestive tract, taking thousands of high-resolution images along the way. The images are transmitted to a data recorder worn by the patient, which is later reviewed by a doctor. The capsule is typically passed through the stool within a few days and does not need to be retrieved. Capsule endoscopy is a safe and effective way to examine the small intestine without the need for sedation or insertion of an endoscope. The procedure is painless and requires minimal preparation, although patients will be asked to fast for several hours beforehand. Capsule endoscopy is particularly useful for detecting small bowel diseases that may not be visible with other diagnostic tests, and it has been shown to have a high diagnostic yield for a range of conditions. However, it is not appropriate for all patients, including those with swallowing difficulties, bowel obstructions, or certain medical devices in the body. Your doctor can help determine if capsule endoscopy is the right option for you.
