Colorectal polyps are superfluous organisms that protrude from the mucosa into the intestinal cavity, either with or without a tip; they can be solitary or multiple. They are divided into tumor polyps (adenomatous polyps) and non-tumor polyps (hyperplastic, inflammatory, malignant polyps, etc.). When the number of colorectal polyps exceeds 100, it is called polyposis. The importance of colorectal polyps lies in their association with colorectal cancer. Most colorectal cancers (>80%) arise from carcinoma of colorectal adenomatous polyps, and timely removal of colorectal polyps can reduce the risk of colorectal cancer in individuals by 70-90%. Colorectal polyps are mostly asymptomatic and are often found incidentally during physical examination or colonoscopy. Some cases may manifest as blood in stool, mucus stool, intestinal obstruction, and prolapsed polyps. Adenomatous polyps are precancerous lesions and should be removed once found, regardless of their size. It is believed that non-adenomatous polyps rarely become malignant, but recent studies have shown that there is still a certain percentage of malignant changes, and more importantly, it is difficult to distinguish tumor polyps from non-tumor polyps under the naked eye, therefore, no matter what kind of polyps, they should be removed surgically. The methods of resection include: endoscopic resection, transanal resection, transabdominal surgery, etc.
