Although various traction devices exist for endoscopic submucosal dissection (ESD), the effects of material used in on human body has not been considered. Moreover, there no report a device that facilitates both oral and anal side lesion. We made deleterious is noninvasive, easy to use, enables bilateral approach ESD. process its creation prospective evaluation usage actual ESD procedures. This study case control study. Thirty-seven patients whom would be were consecutively prospectively enrolled (device group). Control subjects who had lesions matched size location with those group randomly selected Both groups classified into three subgroups according treatment difficulty: A: easy; B: intermediate; C: difficult. The time per cm2 each was examined. Dissection times group/device as follows: A, 5.8/2.1 min/cm2 (p < 0.01); B, 6.1/3.8 0.05); C, 7.9/3.6 0.01), respectively. newly developed medical ring shown feasible safe allowed excellent visualization through suitable tension facilitated rapid gastric
