Atrophic gastritis review does not need to do magnifying gastroscopy, review of ordinary gastroscopy can be; on the suspicion of moderate to severe intestinal epithelial hyperplasia, heterogeneous hyperplasia and carcinoma, etc., the feasibility of magnifying gastroscopy. Magnifying gastroscopy is a digestive endoscopic examination method that adds a zoom lens on the basis of ordinary electronic gastroscope to make the mucosal tissues optically magnified by 1.5~150 times, which is mostly applicable to the identification of benign and malignant nature of gastrointestinal mucosal lesions as well as the follow-up of precancerous gastrointestinal lesions. The diagnosis of atrophic gastritis is clear, so there is no need to do magnification gastroscopy, but it is necessary to review the gastroscopy regularly. Atrophic gastritis is a chronic gastric disease in which the epithelium of the gastric mucosa suffers repetitive damage leading to a reduction in the number of intrinsic glands, with or without intestinal adenosis and/or pseudopyloric adenosis. In patients with atrophic gastritis, intestinal epithelial hyperplasia, heterogeneous hyperplasia and carcinoma may occur on the basis of this pathology, which can be identified by magnified gastroscopy. It is recommended that the patient undergoes regular follow-up gastroscopy to observe the progress of the disease.
