Outline of Research at the Start

小児は手術後も成長発達するため、その成長発達を阻害しない低侵襲手術が望まれている。新生児や乳児の内視鏡手術は小さなworking spaceの中で、脆弱な組織を丁寧に処理しながら、複雑な手技を完遂させなければならないが、患者数が少ないことから、手術手技をon the job trainingとして学びつつ、手術を行っている現状がある。これを防ぐためにoff the job trainingを充実させることが急務である。練習時の手術手技をリアルタイムに画像解析するシステムを作成し、早く上手になる練習プログラムを確立すると同時に実際の手術時の手技評価もできる画像解析プログラムを作り上げる。

Outline of Final Research Achievements

Endoscopic surgery on neonates and infants requires the completion of complex procedures while carefully handling fragile tissues, but the small number of patients makes it imperative to enhance off the job training. We held three off-the-job training seminars for pediatric surgeons using our simulators for esophageal atresia, duodenal atresia, and congenital biliary dilatation , with more than 90 pediatric surgeons participating. All participating pediatric surgeons stated that practicing with the simulator was meaningful and should be continued in the future. 3D analysis of forceps movement was completed, and AI image analysis can now be used to determine how well a technique is performed on the simulator for esophageal atresia.

Academic Significance and Societal Importance of the Research Achievements

新生児や乳児の内視鏡手術は脆弱な組織を丁寧に処理しながら、複雑な手技を完遂させなければならないが、患者数が少ないことから、off the job trainingを充実させることが急務である。我々が作成した、食道閉鎖症などのシミュレータを用いたoff the job trainingセミナーを3回開催し、90名以上の小児外科医が参加し、参加したすべての小児外科医がシミュレータの有用性を指摘した。シミュレータ上での手術操作を3次元解析し、手技の上手さをAI画像解析で判定できるようになったため、今後はより効果的なoff the job trainingが行えるようになった。
