Gastric polyps are usually treated by endoscopic interventions as follows: 1. Cautery: Cautery by argon knife to carbonize polyps; 2. Radiofrequency ablation: Polyps elimination by thermochemical reaction; 3. Electrocoagulation sleeve cutting: One-time removal from the surface of gastric mucosa by means of a trap; 4. EMR and ESD: For polyps with a diameter of 1-2 cm or more and early cancerous lesions; EMR refers to gastric mucosal resection by submucosal injection and removal of polyps by means of a trap; ESD refers to submucosal dissection, mainly for larger tumors, which requires pathological examination.
