Assessment
Primary outcomes
To compare the qualitative diagnostic performance of M-NBI observation using the vessel plus surface classification system for early gastric cancer detected after H. pylori eradication and early gastric cancer currently infected with H. pylori.
Key secondary outcomes
1. To compare the qualitative diagnostic performance of conventional white-light observation including dye endoscopic observation using color plus surface classification system for gastric cancer after H. pylori eradication and gastric cancer currently infected with H. pylori.
2. To compare the diagnostic performance of M-NBI and C-WLI+CE for the horizontal extent of early gastric cancer by M-NBI and C-WLI+CE for gastric cancer after H. pylori eradication and gastric cancer currently infected with H. pylori.
3. To compare the diagnostic performance of M-NBI and C-WLI+CE for the diagnosis of gastric carcinoma after H. pylori eradication and gastric carcinoma infected with H. pylori by histopathological classification into low atypia and other lesions.
4. To compare the range diagnostic performance of M-NBI and C-WLI+CE for gastric cancer after H. pylori eradication and gastric cancer currently infected with H. pylori according to the presence or absence and extent of noncancerous epithelial covering on the surface of intramucosal carcinoma nests.
