Figure 6. Pocket creation method (PCM) with tunneling technique with IT knife nano®. (A) A tunnel is made after continuing submucosal dissection by PCM (yellow arrow). (B, C) The blade of the IT knife nano is put on the edge of the tunnel and moved a little to the outside (blue arrow). (D-F) The procedure is performed repeatedly (direction to the blue arrow), and submucosal tissue is resected safely even if fibrosis exists.
