 Standard magnifying endoscopy has approximately 100-fold magnifying power. IPCL pattern is diagnosed with it. NBI(narrow band imaging)system is extremely useful to effectively recognize IPCL as a brown spot. In IPCL type classification, type I mainly includes normal epithelium. Type II corresponds to inflammatory change or non-neoplastic tissue and type III reflects border-line lesions. Type IV strongly suggests carcinoma in situ. Type V-1is definitely diagnosed as carcinoma in situ.

 Endocytoscopy has approximately 500-fold magnification, which enables observation of cell and nucleus. Endocytoscopic images are classified into five categories from normal epithelium to malignant tissue as ECA classification(endocytoscopic atypism classification). ECA IV and V are considered to be treated in a clinical setting.
