Polypectomy Snare

A polypectomy snare is an endoscopic instrument: a wire loop on a sheath that is closed around a polyp to cut it. Here snare means this medical device, not a drum part. It is passed through the working channel of the endoscope, and the cut can be made cold, with no current, or with high-frequency current.

A cold snare closes the loop around the polyp and cuts it without current. A hot snare cuts with electrosurgical current. ESGE 2024 recommends cold snare polypectomy for polyps up to 9 mm, and does not recommend removal with cold biopsy forceps because of incomplete resection. For a non-pedunculated adenoma of 10 to 19 mm it recommends hot snare, and for 20 mm and larger conventional EMR (Ferlitsch et al., Endoscopy 2024;56:516-545). A snare with both options in one product is on the AGS snare page.

The instructions for use of the single-use polypectomy snare describe it. The loop is drawn back into the sheath for passage through the working channel. The distal end of the sheath is placed in front of the polyp, the loop is extended fully and the polyp is caught, and the loop is tightened round the base of the polyp. With a high-frequency generator and an active cord the current is applied, the loop is drawn back into the sheath to cut the polyp, the current is stopped and the snare is withdrawn. Other tissue must not touch the loop while current is applied.

Both are supplied, and the difference is reprocessing. The single-use snare comes sterile with a 36 month shelf life. The reusable snare is supplied non-sterile, is steam sterilized before every use and is allowed no more than 30 cycles; eleven of its models also carry an MR unsafe statement on the label, which is the line to check before a patient goes into the scanner.

Three loop shapes are supplied in the single-use family: an oval loop on fifteen models, a hexagonal loop on three and an asymmetric loop on two. The models table gives the loop shape of every order number.
