Gastric enterocytosis is still a long time away from gastric cancer, usually at least five to ten years. The appearance of intestinal glandular epithelium in gastric mucosa is a common lesion of gastric mucosa, and the gastric mucosal glands with intestinal chemosis are called chemosis atrophy, i.e. intestinal chemosis. In mild cases, only a few intestinal epithelial cells appear in gastric mucosa, while in severe cases, intestinal villi can be formed. The pattern of gastric cancer is normal gastric mucosa → chronic inflammation → atrophic gastritis → intestinal metaplasia → precancerous lesions → gastric cancer (Correa pattern), therefore, gastric mucosal atrophy and intestinal metaplasia, gastric low-grade intraepithelial neoplasia, are the independent risk factors for the development of gastric cancer. Gastric mucosal atrophy and intestinal metaplasia are categorized as precancerous states, and intraepithelial neoplasia is categorized as precancerous lesions. It is recommended that patients with gastrointestinal symptoms should go to the hospital for regular review of gastroscopy and improve the test of Helicobacter pylori, if positive, the quadruple therapy to eradicate Helicobacter pylori. If in doubt, consult a specialized doctor.
