If the pathology suggests simple intestinal epithelial hyperplasia, the patient can be rechecked in 1-2 years, if the intestinal epithelial hyperplasia is accompanied by low-grade intraepithelial neoplasia, the patient can be rechecked by gastroscopy in 3-6 months, and if the intestinal epithelial hyperplasia is accompanied by high-grade intraepithelial neoplasia, the patient can be operated immediately. If the pathology suggests simple intestinal epithelialization, the possibility of cancer is relatively small, and the patient can have a repeat gastroscopy once every 1-2 years to monitor the extent and severity of the intestinal epithelialization. If the pathology suggests that the epithelialized intestinal lesions are accompanied by low-grade intraepithelial neoplasia, the risk of cancer is higher, and it is recommended that the patient should have a repeat gastroscopy in 3-6 months. If intestinal epithelialization is accompanied by high-grade intraepithelial neoplasia, the patient needs to be treated as early gastric cancer and undergo endoscopic mucosal dissection, and the gastroscopy should be reviewed regularly after the operation. If there is any discomfort, it is recommended to consult the doctor in time to avoid delaying the condition.
