This depends upon the type and size of polyp you have. Small polyps may be removed using biopsy forceps (cupped forceps). Stalked polyps are usually removed using a snare (wire loop) through which a small amount of electrical current is passed (diathermy).  Flat polyps are often removed by a procedure called EMR (Endoscopic Mucosal Resection). This is where fluid is injected under the polyp to raise the polyp up on a cushion, to make it easier to see and remove. The snare is then used to capture and remove the polyp. To use the snare we need to place a sticky pad, usually to the top of your leg. This will be removed at the end of the procedure.
