Gastroscopic pathology atrophy (++), enterosis (++++), and partial dilatation of the glands are the pathologic changes of chronic atrophic gastritis with enterosis. Pathologic changes in chronic atrophic gastritis are inflammation, atrophy, chemosis, and heterotrophic hyperplasia. Atrophy is defined as thinning of the gastric mucosa, smaller and fewer glands in the lesion area, accompanied by shallowing of the gastric recess and fibrosis of the lamina propria. Multifocal atrophy affecting the antrum and body of the stomach increases the risk of developing gastric cancer. Enterosis, i.e. intestinal epithelial hyperplasia, is a common manifestation of gastric adenosis, which refers to the transformation of gastric mucosal epithelium into small or large intestinal mucosal epithelial tissue under long-term inflammation. The wider its distribution, the higher the risk of gastric cancer. (+++), (++++) and so on represent the degree of lesions, which generally indicates the occurrence of heavier atrophy and intestinalization. And in the process of chronic inflammation to gastric cancer, the precancerous state of the stomach includes atrophy and intestinal epithelialization. If there is any gastroscopic pathology of atrophy and intestinalization, it is recommended to go to the hospital as soon as possible, and the doctor will formulate the diagnosis and treatment plan according to the specific condition, so as to avoid the progression of the disease.
