| [ Summary ] | Gastric cancer after successful Helicobacter pylori (H. pylori) eradication therapy should be recognized as a specific category of gastric cancer, and the clinical characteristics should be well characterized and understood. The characteristics under white light endoscopy are small and obscure, which makes the detection of lesions difficult. Furthermore, narrow‒band imaging endoscopy can also be problematic because the demarcation line of lesions can become unclear due to its gastritis‒like appearance. Therefore, careful endoscopy is required for patients after the eradication of H. pylori. Periodical endoscopic surveillance is necessary because the incidence of metachronous gastric cancer never fully dissipate, even if H. pylori is successfully eradicated. Endoscopic surveillance, at intervals shorter than 12 months, should be considered from the viewpoint of stomach preservation. | |
