Efficacy of forced coagulation with low high-frequency power setting during endoscopic submucosal dissection

Figure 1 Process of the vessel-sealing with endoknife compression technique. A: The vessel penetrating between the muscularis propria is exposed; B-D: The vessel is compressed by the FlushKnife-BT 2.5 mm and coagulated using the S method or F method until the color turned white, which indicates a complete desiccation of the vessel. If it does not turn white completely, we tried this method from the other side; E and F: Finally, the vessel is cut with the FlushKnife-BT 2.5 mm using the forced coagulation mode (Effect 3, 50 W).
