Whether gastric polyps 0.8cm must be surgically treated, which is based on the morphology, structure, nature and other factors to make an objective analysis. 1, if the 0.8cm gastric polyp surface is smooth, regular shape, relatively clear borders, no obvious bleeding, ulcers and other symptoms. In this case, the gastric polyps are mostly considered benign lesions, and patients are advised to remove them under gastroscopy or dynamic review of gastroscopy. If, during the review of the changes in gastric polyps, the volume of gastric polyps is found to increase progressively, and the surface is accompanied by erosion, bleeding or even causing pain, patients are advised to perform endoscopic removal of gastric polyps as soon as possible. 2. If the patient’s gastric polyps have unclear borders, irregular morphology, and cauliflower-like changes on the surface, at this time It is highly suspected that gastric polyps become cancerous. It is recommended that the patient should undergo surgery to remove the diseased tissues in the stomach, and if necessary, the peripheral lymph nodes should be cleared to completely remove the gastric polyps and tumor cells.
