Cold versus hot endoscopic mucosal resection for nonpedunculated colorectal polyps sized 6–10 mm: a randomized trial

Papastergiou et al.

Fig. 1 Example of cold snare endoscopic mucosal resection (CS-EMR). a, b Polyp detected (a) and observed by narrow-band imaging (b). c Submucosal injection of a methylene blue-tinted normal saline solution. d, e The polyp and a rim of normal surrounding tissue were ensnared without tenting (d), and transected mechanically (e). f Visual inspection of the CS-EMR mucosal defect revealed presence of a white protrusion.
