Since National Health Insurance covered eradication therapy for H. pylori infected gastritis, all patients with H. pylori infection could be received eradication under insurance. Cure of H. pylori infection improves histological gastritis, also atrophic change, and intestinal metaplasia. Prevention of H. pylori associated diseases such as gastric cancer is expected. According to Insurance instruction, it is carried out in order of endoscopic diagnosis of chronic gastritis, diagnosis of H. pylori infection, and eradication treatment. Endoscopic examination prior to H. pylori diagnosis is necessary for screening of gastric cancer. Endoscopic finding of RAC (regular arrangement of collecting venules) in the angle of stomach suggests lack of infection with H. pylori, disappearance of RAC suspects H. pylori infection.
自从国民健康保险涵盖了幽门螺杆菌感染性胃炎的根除治疗后，所有幽门螺杆菌感染患者都可获得保险范围内的根除治疗。幽门螺杆菌感染的治愈可改善组织学胃炎，以及萎缩性改变和肠化生。有望预防幽门螺杆菌相关疾病，如胃癌。根据保险指令，按慢性胃炎的内镜诊断、幽门螺杆菌感染诊断和根除治疗的顺序进行。在幽门螺杆菌诊断之前进行内镜检查对于胃癌筛查是必要的。胃角部出现RAC（集合小静脉规则排列）的内镜表现提示无幽门螺杆菌感染，RAC消失则怀疑幽门螺杆菌感染。
