Colon capsule endoscopy compared to colonoscopy for colorectal neoplasms diagnosis: an initial experience and a brief review of the literature.

Conventional colonoscopy is regarded as the gold standard procedure for the diagnosis of colorectal neoplasms despite its several limitations including invasiveness, discomfort and potential complications. Colon capsule endoscopy (CCE) could be an attractive alternative method to the invasive colonoscopy for the diagnosis of colorectal cancer and polyps. Publications regarding the use of CCE for detecting colorectal cancer and polyps, as well as our experience, were reviewed. The new second-generation CCE (PillCam COLON 2) has improved accuracy compared with the first-generation system for detecting colorectal neoplasms.
