Endoscopic submucosal dissection (ESD) in patient with gastric superficial neoplasms is wide spread. Accordingly, many devices have developed. The Stag-Beetle knife GX (SB-GX) was on sale in 2016 and was introduced to our institution. In this study, we sought to investigate its efficacy. We included 112 lesions from 168 patients with gastric neoplasms who underwent ESD between 2014 and 2017. Lesions were divided into the GX group, which used SB-GX, and Dual group, which used Dual knife. No significant difference was observed in treatment results between either group. Propensity score matching demonstrated that procedure time tended to be shorter in the GX group than in the Dual group, without an increase in adverse events. Unfortunately, the usefulness of SB-GX in patients with gastric ESD was not verified in this study. Further studies that include more cases are warranted.
