Aim : We investigated the correlation between ordinary endoscopic and magnifying endoscopic findings, characteristic for small gastric cancers of depressed-type.

 Methods : Nineteen cases of gastric cancer and 19 measuring below 10mm were included in this study. Both ordinary and magnifying endoscopic findings were reviewed intensively in order to investigate from the findings which were visualized by magnification endoscopy how mucosal color and structural changes in ordinary endoscopic findings have originated.

 Results : Endoscopic color change in ordinary endoscopic findings depended upon microvascular density and architecture as visualized by magnification endoscopy. Both irregular distribution of endoscopic color by ordinary endoscopy and irregular microvascular pattern by magnification endoscopy were characteristic for these carcinomas. The irregularity of the margin of the lesion in ordinary endoscopy was also a helpful maker for discriminating cancers from gastritis. However, irregular demarcation line visualized by magnification endoscopy was remarkable in carcinoma(84.2%), while it was nil in gastritis(0 %).

 Conclusion : In clinical practice, a combination of ordinary and subsequent magnified endoscopic observation using the findings described here is mandatory in order to make a correct diagnosis of small gastric cancer by zoom endoscopy.
