Capsule endoscopy is a non-invasive diagnostic procedure, which involves swallowing a small, ingestible capsule equipped with a miniature camera which navigates through the digestive tract, capturing high-resolution images of the small intestine.
The capsule, typically the size of a large pill, is swallowed by the patient and travels naturally through the digestive system. As it progresses, the camera captures thousands of images, transmitting them wirelessly to a recorder worn on the patient’s body. These images are later analyzed by your doctor to diagnose conditions like Crohn’s disease, celiac disease, or obscure gastrointestinal bleeding.
Capsule endoscopy offers thorough examination of the small intestine; an area which is not typically accessed by upper or lower endoscopy.
Despite its benefits, capsule endoscopy has limitations. It does not allow for therapeutic interventions, such as biopsy collection or polyp removal. Furthermore, capsule endoscopy is not for everyone and history of bowel obstruction is a contraindication.
A clear liquid diet and overnight fasting may be recommended to ensure a clear view of the small intestine. It’s crucial to follow your healthcare provider’s instructions closely for the best results.
