Background/Aims: We developed a new endoscopic submucosal dissection (ESD) simulator and evaluated its efficacy and realism foruse training endoscopists. Methods: An ESD simulator was constructed using polyvinyl alcohol hydrogel sheets and compared to a previous ESD simulator. BetweenMarch 1, 2020, and December 30, 2021, eight expert endoscopists from three different centers analyzed the procedure-relatedfactors of the simulator. Five trainees performed gastric ESD exercises under the guidance of these experts. Results: Although the two ESD simulators provided overall favorable outcomes in terms of ESD-related factors, the new simulator hadseveral benefits, including better marking of the target lesion’s limits (p<0.001) and overall handling (p<0.001). Trainees tested the usefulnessof the new ESD simulator. The complete resection rate improved after 3 ESD training sessions (9 procedures), and the perforationrate decreased after 4 sessions (12 procedures). Conclusions: We have developed a new ESD simulator that can help beginners achieve a high level of technical experience before performingreal-time ESD procedures in patients.
