ロボット支援手術（RAS）の炭素フットプリントを、製造・サプライチェーン・麻酔・廃棄を含むライフサイクル全体でレビューした。報告値は術式や施設、器具の再利用、評価境界により大きく変動し、RASが腹腔鏡・開腹より高い場合も低い場合もある。GRADE準拠の系統的レビューでは術中環境影響が最大とされたが証拠の質は低い。主因は使い捨て器具や手術室インフラ、麻酔であり、Scope 3の未解明領域が課題となる。

English

This review examines the carbon footprint of robot-assisted surgery across its full lifecycle, including manufacturing, supply chains, anesthesia, and waste. Reported emissions vary widely by procedure, setting, instrument reuse, and lifecycle boundaries, with a GRADE-based review finding RAS had the greatest intraoperative impact but low-quality evidence. Single-use instruments, OR infrastructure, and anesthesia—not the robot alone—are major contributors, with poorly characterized Scope 3 categories a key gap.

📄 Abstract（原文）

Robot-assisted surgery (RAS) has become an integral component of modern surgical practice, driven by perceived technical advantages and expanding indications. As these systems become increasingly embedded in routine care, their environmental implications warrant closer examination. The concept of a "carbon footprint" provides a useful framework for understanding the total greenhouse gas emissions associated with surgical care, extending beyond intraoperative energy use to encompass manufacturing, supply chains, anesthesia, and waste. Drawing on lifecycle assessments and comparative studies, this review examines the sources and magnitude of carbon emissions associated with RAS. Reported environmental impacts vary by procedure, institutional setting, instrument reuse, and lifecycle boundaries, with individual studies showing both higher and lower emissions for RAS than laparoscopic or open alternatives. However, a recent GRADE-based systematic review found that RAS had the greatest intraoperative environmental impact among evaluated approaches, although evidence quality was low to very low. Major contributors include single-use instrumentation, operating-room infrastructure, and anesthetic practices rather than the robotic platform alone. The increasing complexity of contemporary robotic systems, including their reliance on advanced instrumentation, digital infrastructure, and high-performance computing, further complicates assessment of embedded and downstream emissions, particularly within poorly characterized Scope 3 categories. At the same time, several contributors to the carbon footprint of RAS appear modifiable through changes in peri-operative practice, procurement strategies, and system design. As robotic surgery continues to expand globally, a clearer understanding of its environmental impact is essential to ensure that technological innovation proceeds in parallel with ethical stewardship and sustainable health-system planning.
