DETECTION OF COLORECTAL POLYP USING IMAGED-ENHANCED ENDOSCOPY

Abstract

Studies report that endoscopic resection of adenomatous polyps lowers the risk of colorectal cancer (CRC) and death. Therefore, colonoscopy plays a key role in preventing CRCs. In addition, high-quality colonoscopy is required to fulfill its role effectively and improve the adenoma detection rate for endoscopists. In contrast, since most post-colonoscopy CRCs (PCCRC) are caused by missed lesions, missed lesions as well as new lesions should be evaluated henceforth. Imaged-enhanced endoscopy (IEE) utilizing the optical digital method can be performed with a single click without using other devices or staining. Recent advances in endoscopic technology and the development of new IEEs have demonstrated the usefulness of IEEs in the detection and prevention of missed lesions in addition to their characterization. In this article, we describe the current state of colorectal polyp detection as well as the procedure and evidence for IEE observation during a colonoscopy. It is necessary to pursue the optimal observation method using IEE.
