Snare Polypectomy We have discussed the use of the biopsy forceps to remove polyps. That technique is generally limited to the removal of smaller polyps-usually less than 5 millimeters. Larger polyps are generally removed using the snare technique. Just like the use of biopsy forceps, snares can be "hot" or "cold"-meaning that electrocautery is used or not used. A snare is basically a wire lasso that is placed around a polyp, then tightened around the polyp tissue to cut off the polyp.
