Outline of Research at the Start

医療事故調査はカルテレビューと根本原因分析法で構成されるが、医療関連死の場合には医学的解析も必須である。しかし、解析の根幹をなす病理解剖は病理医不足や遺族感情から実施困難な状況にある。そこで、本研究は医工連携で遺体損傷を最小化できるロボット活用「低侵襲解剖」に、解剖情報を補完する人工知能(AI)支援「死亡時画像診断(Ai-CT)」と「検体検査」を併用した医療関連死の原因究明法を確立する。
具体的には診断精度の観点から「低侵襲解剖」に必要最低の標本を摘出可能な解剖用ロボットを開発する。次に低侵襲解剖を補完・診断支援を担うAIを開発する。さらに教育システムを構築し医育面からも解析能向上を目指す。

Outline of Final Research Achievements

In autopsies of medically related deaths, injury to the body is often a barrier to obtaining family consent. This study focused on developing the basic technology for a minimally invasive autopsy robot that minimizes skin incisions while still allowing for the necessary sampling of major organs, and developing methods to supplement the missing autopsy information through minimally invasive autopsies. Based on the results of a study of the minimum amount of tissue needed to determine the cause of death, we developed a robotic head capable of cutting tissue on a cylinder 2 x 3 cm in size. In addition, we attempted to develop an objective diagnosis method for sepsis, a high-resolution (super-resolution) lung image from postmortem CT, an organ weight estimation method and its application, and a postmortem time estimation method to supplement the insufficient autopsy information. Our findings would also help protect medical personnel from emerging infections.

Academic Significance and Societal Importance of the Research Achievements

本研究は、医療関連死を含む死亡症例の正確な病態や死因究明を行うためには、基本的に全身解剖が必要であることを改めて認識させると共に、それが困難な場合は主要臓器からプレパラート各1枚の大きさ程度の組織採取が必須であることを明らかにした。また、近年、新興感染症が猛威を振るう中、解剖ロボットと外科ナビゲーションを連動させることにより、将来的に医療者安全に重要な遠隔解剖への道を拓く結果となった。さらに、今後、医学教育素材の一般公開を進めていく中で、革新的な医用画像教育の構築が可能となることも期待できる結果となった。
