Abstract：
BACKGROUND: Endoscopic submucosal dissection (ESD) requires high endoscopic technical skills, and trainees should develop effective training methods. In collaboration with KOTOBUKI Medical, we developed the G-Master, which is a non-animal training model that can simulate various parts of gastric ESD. We aimed to clarify the usefulness of the G-Master for inexperienced ESD trainees.
METHODS: We collected data from the first 5 gastric ESD cases conducted by 15 inexperienced ESD trainees at 5 participating centers between 2018 and 2022. The participants were divided into two groups: the G-Master training and non-G-Master training groups. Outcome measurements, such as procedural speed, perforation rate, self-completion rate, and en bloc resection rate, were compared between the two groups retrospectively.
RESULTS: A total of 75 gastric ESD cases were included in this study. The G-Master training group included 25 cases performed by 5 trainees, whereas the non-G-Master training group included 50 cases performed by 10 trainees. The median procedural speed for all cases was significantly faster in the G-Master training group than in the non-G-Master training group. Moreover, the procedural speed was linearly improved from the initial to the last cases in the lower location in the G-Master training group compared with the non-G-Master training group. In addition, although there was no significant difference, the G-Master training group showed lower rates of perforation and a lesser need to transition to expert operators than the non-G-Master training group.
CONCLUSIONS: The G-Master could improve the ESD skills of inexperienced ESD trainees.

摘要：
背景：内窥镜粘膜下剥离术（ESD）需要很高的内窥镜技术技能，学员应制定有效的培训方法。与KOTOBUKIMedical合作，我们开发了G-Master,这是一种非动物训练模型，可以模拟胃ESD的各个部分。我们旨在阐明G-Master对缺乏经验的ESD学员的有用性。
方法：我们收集了2018年至2022年间由5个参与中心的15名没有经验的ESD学员进行的前5例胃ESD病例的数据。参与者分为两组：G-Master培训和非G-Master培训组。结果测量，比如程序速度，穿孔率,自我完成率，和整块切除率，对两组进行回顾性比较。
结果：本研究共纳入75例胃ESD病例。G-Master培训组包括由5名学员执行的25个案例，而非G-Master培训组包括由10名学员执行的50例病例。在G-Master训练组中，所有病例的中位程序速度均明显快于非G-Master训练组。此外，与非G-Master训练组相比,在G-Master训练组的较低位置,从最初到最后的病例,程序速度线性提高.此外,虽然没有显著差异,与非G-Master培训组相比,G-Master培训组的穿孔率较低,并且过渡到专家操作人员的需要较少.
结论：G-Master可以提高没有经验的ESD学员的ESD技能。
