Efficient hemostatic method for endoscopic submucosal dissection of colorectal tumors

Figure 3 Clinical use of the new method in endoscopic submucosal dissection for colorectal tumors. A: A vessel with a diameter of 1 mm was detected; B: It was coagulated in the soft coagulation mode. Thereafter, the vessel and the surrounding submucosa became whitish, and the submucosa became less elevated. Submucosal dissection with a knife was slightly difficult because of the obscured view of the submucosa and the proximity of the muscularis propria; C: The whitish coagulated vessel was removed using the hemostatic forceps in the “endocut” mode. Subsequently, the whitish surrounding submucosa was dissected using the forceps. Thereafter, the view of the submucosa was improved.
