Outline of Final Research Achievements

In this study, we developed a training method that focuses on the surgeon's spatial cognitive abilities. First, we proposed a classification method using machine learning with our HUEAD as a method to evaluate the validity of endoscopic surgical procedures. higher value. Next, we investigated the effect of spatial cognition training on endoscopic surgery. The results of comparing the rate of improvement in endoscopic surgical technique showed that there was a significant improvement in the accuracy of forceps manipulation in the spatial cognition training group (p=0.029). There was no significant difference in speed of forceps manipulation or misalignment of forceps manipulation (p=0.581, (p=0.999). This suggests that spatial cognition training is a reasonable training to improve spatial cognition.

Academic Significance and Societal Importance of the Research Achievements

内視鏡外科手術などの低侵襲手術は，医療のあり方を根本的に変えてきた。しかしながら内視鏡外科は従来の開腹手術と異なるため，特別なトレーニングが必要となる。さまざまなトレーニングが開発され効果が認められているが，トレーニングボックスの前でないと実施できないトレーニングは時間と場所の制約が大きい。そこで本研究では内視鏡外科手術に重要だとされている空間認知能力に焦点を当て，空間認知能力トレーニングを開発した。その結果空間認知能力トレーニングは術者の鉗子操作の正確性を向上させることが明らかになった。またこのトレーニングは空間認知能力が低い人ほど有効であることが明らかになった。
