 Minute(≦5mm in size)epithelial neoplastic lesions display a high incidence of adenoma and a low incidence of carcinoma. Therefore, magnifying endoscopic observation by narrow band imaging(NBI)need to be performed only for those lesions suspected of being caused by high-grade adenoma or carcinoma, identified by conventional endoscopy. However, small(6-10mm)epithelial neoplastic lesions have a high incidence of carcinoma and low incidence of adenoma compared to minute lesions. Thus, it is necessary to perform magnifying endoscopic observation using NBI for the lesions suspected of being caused by carcinoma and observe the pit patterns in the lesions by crystal violet staining.
