Endoscopic removal of intestinal polyps is actually very simple, mainly due to the development of medical devices nowadays. The endoscope is passed through the anus into the intestinal cavity and extends upward to the ileocecal valve, which is the entire scope of the endoscopic exploration. If an intestinal polyp is found, the nature and size of the polyp will be initially distinguished by endoscopy, and for polyps suspected of having malignant changes, they can be clamped with a trocar. The instruments will be passed through the endoscopist’s assistant and penetrate deep into the intestinal cavity through the instrument entrance under the e-colonoscope, then the polyp will be found under the colonoscope’s illumination to clamp the polyp and finally clamp off. The polyp is then simply yanked out by the original route and placed in a formalin specimen box.
