The principle of treatment of rectal polyps is to remove the polyps as soon as they are found. At present, the method of polyp removal is mainly endoscopic removal method. According to the shape, size, number and the presence or absence of polyps, length and thickness of polyps are used: 1, high-frequency electrocoagulation trap removal method: mainly for polyps with tips; 2, high-frequency electrocoagulation cauterization method: mainly for multiple small polyps in the hemisphere; 3, high-frequency electrocoagulation hot biopsy clamp method: rarely used, mainly replaced by ② ④ method; 4, biopsy clamp method: mainly for single or a few small spherical polyps, simple and easy to use, and 5.Laser vaporization method and microwave heat transmission method; suitable for those who do not need to keep histological specimens; 6.Mucosal peeling and inlaying method: mainly used for flat polyps or early cancer patients; 7.”Dense connection” removal method, mainly used for long-tipped large polyps, difficult to suspend in the intestinal lumen using large polyps dense intestinal wall electrocoagulation removal method. 8.Stage batch removal method, mainly used for patients with more than 10-20 polyps who cannot be removed at one time. 9.The combined endoscopic and surgical treatment method is mainly used for patients with polyposis, i.e., the sparse polyp area is surgically removed, so that the treatment purpose can be achieved and the normal function of the large intestine can be maintained. As rectal polyps, especially adenomatous polyps have been recognized by scholars as pre-cancerous lesions. Therefore, the regular follow-up of rectal polyp patients has been highly recognized to prevent and treat early rectal cancer.
