Cold snare polypectomy is an easy-to-apply technique and has been the most popular technique esprcially for small and diminutive polyps. Briefly, 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, until complete closure is achieved and the polyp is guillotined. The polyp can then be suctioned and retrieved for histologic assessment.
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. The polyp can then be suctioned and retrieved for histologic assessment.
