| Research Abstract |
We developed objective endoscopic diagnostic system based on microvascular architecture as visualized by magnifying endoscopy with narrow-band imaging. We developed program for extraction of microvascular architecture by image analysis. We conducted multicenter prospective study in order to test validity of the method and then we showed that the diagnostic performance is excellent using the magnifying endoscopy. Furthermore, we found phenomenon that gastric epithelial neoplasia acquired function of lipid absorption during this study. And then, we applied this phenomenon and we developed novel endoscopic diagnosis method which enables endoscopist to detect an early gastric cancer efficiently.
