Gastric polyps around 0.4cm are not particularly serious, so don’t worry too much. Because gastric polyps mostly occur in the gastric body or stomach bottom, often around 0.2-0.5 cm, most of these polyps originate from the mucosal layer, and few are seen in the submucosal layer, which can become proliferative manifestations, and most of the pathological manifestations are caused by chronic inflammatory hyperplasia. Gastric polyps are recommended endoscopically, and electrodesiccation with a trap is a more effective way to address gastric polyps, with less trauma, quicker prognosis and faster recovery of the trauma. If these polyps are not given endoscopically, you can consider reviewing gastroscopy in about 1.5 to 2 years, and if the polyps are found to be not significantly enlarged, you can consider reviewing gastroscopy in about 2-3 years for follow-up observation. In conclusion, two approaches can be used for gastric polyps: one is endoscopic resection; the other is review gastroscopy in 1-2 years with follow-up observation, which is not particularly serious.
