Surgical removal of small polyps found on colonoscopy is usually recommended. Early removal for definitive diagnosis can prevent colorectal cancer. Intestinal polyps are divided into adenomatous polyps, hyperplastic and misshapen polyps and inflammatory polyps. 1. Adenomatous polyps: they are precancerous lesions and should be removed immediately even if they are small. There is a risk that they may become cancerous and life-threatening. 2. Hyperplastic and misshapen polyps: although rarely malignant, they should be removed as soon as possible so that the diagnosis can be clarified. 3. Inflammatory polyps with accompanying symptoms: resection is also recommended to help clarify the diagnosis and exclude the possibility of cancer. The vast majority of intestinal polyps can be resected endoscopically. For patients who are not suitable for endoscopy, rectal polyps can be resected through the anus; colonic polyps can be resected laparoscopically or by laparotomy.
