Removal of diminutive colorectal polyps: A prospective randomized clinical trial between cold snare polypectomy and hot forceps biopsy

Figure 3 Technique for hot forceps biopsy. A: A slightly protruded polyp was detected with magnified chromoendoscopy; B: The polyp was captured in the cup of the forceps and gently pulled from the mucosa; C: The electrocautery current was applied to the polyp until the color changed to white at the polyp base. Then the polyp was completely removed from the mucosa; D: Pathologic evaluation of the free cut-margin was difficult to perform because of a thermal tissue injury (arrow).
