Polyps are clinically common in the lumen of the stomach or colon or even the rectum. According to the nature of polyps, they are usually divided into inflammatory polyps and tumor polyps. First, for inflammatory polyps, whether in the stomach or colon lumen or rectal lumen, usually endoscopic electrocautery excision, while post-surgical pathological examination, if the possibility of malignant lesions can be cured by one-stage resection, if confirmed as a malignant tumor, usually need to be further added to do radical resection of the tumor treatment. Secondly, for tumor polyps, generally speaking, for polyps with tips or adenomatous polyps with small base, endoscopic resection is usually adopted, and intraoperative freezing is sent, if it is benign without malignant, complete resection can be cured; if malignant tumor is confirmed by pathology, radical resection of malignant tumors is usually needed. For tumor polyps that are wider at the base, or those that are difficult to resect endoscopically and are prone to bleeding and perforation, they are usually treated with transabdominal or laparoscopic partial resection of the bowel or stomach.
