Cold Snare Polypectomy of Sessile Polyp

A 58-year-old woman undergoes screening colonoscopy and is found to have a 7-mm sessile, salmon-pink polyp in the ascending colon. Narrow-band imaging shows a uniform tubular pit pattern consistent with low-grade adenoma. The endoscopist performs the technique marked **B** in the diagram: a thin dedicated cold snare is opened around the polyp with a 1-2 mm margin of normal mucosa, the snare is closed firmly with steady pressure (NO electrocautery), and the lesion is transected by mechanical guillotine action. The defect shows a clean white base with minimal oozing that stops spontaneously. Which of the following best describes the PRIMARY ADVANTAGE of the technique marked **B** over cold biopsy forceps for this 7-mm sessile polyp?
