Outline of Final Research Achievements

Within the three-year period from April 2019 covered by this research project supported by JSPS, we were able to file a foreign patent application for a mucous membrane tissue model for endoscopic treatment, as well as register a domestic utility model with the development of a new luminal part of stomach to which the therapeutic model is attached. In addition, we reported the results of an educational intervention study using the bleeding ulcer model were reported at major conferences, including the American Gastroenterological Association. Therefore, the effectiveness of the simulator training in endoscopic treatment is being established. In the future, we plan to widely disseminate the simulator training with our novel models and brush up the educational program.

Academic Significance and Societal Importance of the Research Achievements

内視鏡治療のトレーニング用に消化管類似の粘膜構造と血管走行を樹脂素材により再現することで、動物の犠牲を伴うことなく、出血や粘膜の損傷といった内視鏡治療時に起こりえる合併症を練習するシミュレータモデルを開発してきた。出血性潰瘍モデルでは、レジデント医師における学習効果を教育介入研究として証明しており、今回開発されたモデルにより初学者が実際の患者を危険に晒す危険を低減できると考えている。
