Figure 5. A. The lesion on the anti-gravity side is spontaneously flipped up by gravity. B. In the lesion on the ipsilateral side of gravity, mucosal incision is started from the gravity side (①) as the mucosal tension from the opposite side (②) helps open the incised mucosal line. C If the mucosal incision starts from the anti-gravity side (①), the mucosal incision on the gravity side becomes difficult. D. A lesion on the gravity side is the most difficult, and the traction device or changing the patient’s position can be a possible solution.
