 The decline in the rate of H. pylori infection and the spread of eradication of H. pylori have caused changes in the subjects of endoscopic screening and findings for gastric cancer. Endoscopic gastric cancer screening has been recommended since April 2016. If the ADL(activities of daily living)are retained, conducting endoscopic screening seems important even for patients aged 65 and over who are at high risk of gastric cancer. In the case of over 10 years after H. pylori eradication, even if the gastric atrophy is mild-moderate, the risk of diffuse-type gastric cancer increases ; thus endoscopic follow-up by screening is crucial. Intestinal metaplasia is the most important for background gastric mucosal findings after H. pylori eradication, and image-enhancing endoscopies, such as NBI(narrow band imaging)and TXI(texture and color enhancement imaging), are also useful. In recent years, there have also been reports that high-resolution thin scopes have rapidly evolved, and no significant difference has been observed in image quality from conventional scopes. Furthermore, new types of high-resolution thin scopes are believed to be the major tools for gastric cancer screening in the future.
