Figure 1 Consecutive endoscopic images demonstrating the technique of cold snaring. (A) A diminutive polyp in the ascending colon. (B) Narrow banding imaging shows typical features of an adenoma (brown color, thick brown vessels, white oval and tubular surface pattern). (C) The instrument is rotated for polypectomy, to align the polyp with the instrument channel at 5 o'clock. (D) The snare is opened enough to allow a rim of normal tissue to be ensnared and resected. The scope is angled into the colon wall while the snare is pushed forward. (E) Deflation can assist with snaring. (F) The polyp and small rim of normal tissue is snared and guillotined, while the snare sheath remains embedded in the wall (through gentle forward pressure). (G) Without tenting, the polyp tissue remains in the polyp defect for retrieval. (H) A small amount of minor bleeding is typical.
