 Since the 1980's, EGC(early gastric cancers)occur more often in over 60 years old and it was found that lesions of the size in diameter is less than 30mm, histological type is differentiated, and histological invasion is to the mucosal layer are account for 80% of EGC. In addition, the introduction of the IEE(image-enhanced endoscopy)enabled us to detect lesions which are smaller and poorer differentiated type such as lacking of endoscopic characteristics, and to diagnose minute gastric lesions qualitatively with more precision. However, we suggested that the introduction of IEE enabled us to detect more minute gastric cancers but, the frequency of detecting them was no significant difference before and after the introduction of IEE. We consider that the present IEE is limited to the screening test of minute gastric cancers.
