Intestinal polyps are often found under colonoscopy, and their treatment can be divided into endoscopic treatment or surgical resection treatment. Endoscopic treatment refers to the partial or complete removal of polyps under colonoscopy using specialized instruments, such as electric knife, ligatures, etc., and then sent for pathological examination. If the polyp is benign, it is usually possible to follow up about three months after surgery. If it is malignant but the polyp only grows in the mucosal layer and can be removed completely, surgery is not necessary, only close follow-up is needed, but if the invasion is too deep, it needs to be converted to surgery. Surgical resection is necessary for polyps that are large or difficult to treat endoscopically. If the polyp is benign, only partial resection of the intestine is needed, but if the polyp is malignant, radical surgery of the tumor is needed, and chemotherapy and other related treatments are given after surgery.
