PillCam is about the size of a large vitamin capsule. It measures 11mm x 26mm and weighs less than 4 grams. PillCam does not completely replace the colonoscopy. It is still important to view your colon with a colonoscopy – especially when initially diagnosing Crohn's disease. However, in 30% of patients diagnosed with Crohn's, disease activity is confined only to the small bowel. When this is the case, the PillCam capsule may offer an alternative to follow-up colonoscopies. The capsule is disposable and passes naturally with your bowel movement. You shouldn't feel any pain or discomfort. After the procedure, the recorder and sensors will be removed and the images will be made available for your physician to review. There is no recovery time with the PillCam capsule and no need to retrieve or return the capsule.
