Core Tip
Core tip: Single-Charge Coupled Device integrated type endocytoscopy (OLYMPUS, Japan) is going to be newly launched in 2018. Endocytoscopy with approximately 500-fold magnification capability allows us to observe both structural and cellular atypia in vivo, and is expected to be used as an optical biopsy. In our prospective study, we aimed to clarify the diagnostic performance of endocytoscopy in differentiating neoplasia from non-neoplasia for colorectal diminutive polyps (≤ 5 mm). The diagnostic performance of endocytoscopy met the threshold of the Preservation and Incorporation of Valuable endoscopic Innovations statement for “resect-and-discard” and “diagnose-and-leave” strategies.
