Endoscopic submucosal dissection (ESD) might be difficult to perform in some cases even for experienced endoscopists. Recently, various traction methods have been introduced to facilitate ESD procedures, such as clip-with-line (CL), external forceps, clip and snare, internal traction, double scope, and magnetic anchor.The traction procedure using the CL method enhances the visibility of the operation field during ESD. The original CL method is performed as follows: the clip with the line (e.g., dental floss) is attached to the edge of the lesion. Traction can be produced by pulling the line gently, thus achieving a sufficient visualization of the submucosal layer to identify an accurate cutting line. Herein, we present a useful modified two-CL method by pulling the appropriate normal mucosa to enhance the visibility of the operation field during ESD procedure. Thus, the traction methods, including our modified CL technique, might reduce the procedure time and complications.
