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

Figure 5 Macroscopic view after coagulation by the ball electrode with a 3-mm tip and microscopic view after coagulation by the FlushKnife-BT in the porcine block. A: Macroscopic view of the front surface after coagulation using the ball electrode with a 3-mm tip. The coagulation at the left and right is the result of the F1-10 and S methods, respectively; B: Macroscopic view of a transverse section after coagulation using the ball electrode with a 3-mm tip; C: Microscopic view of the hematoxylin-eosin staining after coagulation by the FlushKnife-BT 2.5 mm. The coagulation at the left and right is the result of the F1-10 and S methods, respectively.
