Capsule Endoscopy(CE) is a procedure in which a capsule with a miniature camera is swallowed and it transmits images as it goes through the gastrointestinal tract. It has advantages and disadvantages. While easier on the patient, it does not allow for a biopsy, and if it shows a suspicious findings, full endoscopyto perform a biopsy will still be required. A recent European guideline says that patients at high risk for CRC, because of symptoms or signs consistent with cancer, or a family or personal history of CRC, are at increased risk of advanced colorectal neoplasia and cancer. These patients should be referred to colonoscop, so a biopsy can be immediately performed. However, in patients for whom colonoscopy is inappropriate or not possible, the use of CE could be discussed with the patient (Evidence level 4, Recommendation grade D). A recent review of various guidelines by Shim et al, confirms this recommendation.
