Snare polypectomy was found to be the preferred method for removal of polyps 1 cm or greater in size in a survey of common gastroenterology practices[9]. A snare is a self-contained metal ring that is opened over the polyp and then closed entrapping polyp tissue for resection by closing the ring.

What is a snare polypectomy?
A polypectomy snare is a wire loop device used during colonoscopy designed to slip over a polyp and, on closure, results in cutting the polyp off at its stalk. Conventional snare polypectomy uses cautery, a hot wire with electrical current that cauterizes the tissue while removing the polyp.
How do you do a hot snare polypectomy?
Hot snare polypectomy, the endoscopist advances the snare sheath, opens the snare and encircles the polyp. The snare is then slowly and progressively closed, with the aim of capturing 1-2 mm of normal tissue around the polyp,then use Electrocoagulation until complete closure is achieved and the polyp is guillotined.
What is a single piece polypectomy?
A polypectomy is a procedure used to remove polyps from the inside of the colon, also called the large intestine. A polyp is an abnormal collection of tissue. The procedure is relatively noninvasive and is usually carried out at the same time as a colonoscopy.
How do you perform a polypectomy?
Polypectomy can be done via a colonoscope (a thin, flexible tube) by injecting fluid under the polyp to raise it, after which it is removed with a snare. A heat current in the snare cauterizes tissue at the cut to avoid bleeding. With the aid of a sedative, discomfort is minimal for polypectomy recipients.
