Treatment

Polyps can be removed during a colonoscopy or sigmoidoscopy using a wire loop that cuts the stalk of the polyp and cauterises it to prevent bleeding.^[3] Many "defiant" polyps — large, flat, and otherwise laterally spreading adenomas — may be removed endoscopically by techniques that involve injection of fluid underneath them, to lift them and thus enable them to be taken out. These techniques, when they may be employed, are an alternative to a much-more-invasive colectomy.^[4] Cauterization is a medical term describing the burning of the body to remove or close a part of it. ...
