A polypectomy is the procedure of removing abnormal like growths that protrude into the lining of the bowel (polyps).

Small polyps can be removed with an instrument called biopsy forceps, which takes off small pieces of tissue for examination then destroys the remainder of the polyp by cautery. Larger polyps are usually removed by putting a noose, or snare, around the polyp base and burning through the tissue, also with electric cautery. Neither of these procedures are painful, and you will not be aware that they are being done. Rarely will a polyp be too large to remove by colonoscopy and although sophisticated techniques often allow removal of even these polyps, occasionally surgery will be required for removal.
