 PillCam® COLON capsule endoscopy〔CCE(Given Imaging Ltd, Yoqneam, Israel)〕is one of the most recent diagnostic, endoscopic technologies designed to explore the colorectum. The first generation of CCE was released onto the market in 2006. Recently, a second generation system(PillCam® COLON 2 ; CCE-2)has been developed to increase sensitivity for detection of colorectal lesions. The new CCE-2 has two imagers with a much wider angle of view that has been increased to 172°for each imager, allowing nearly 360°coverage of the colon. CCE-2 captures 35 images per second when in motion and 4 images per second when it is virtually stationary. The per-patient CCE-2 sensitivity for≧6mm was reported as 84~89%. These recent advances in this modality might offer the option to screen noninvasively for colorectal lesions.
