About

Koichi Okuya is a pioneering surgical oncologist whose research focuses on robotic-assisted colorectal cancer surgery and minimally invasive surgical techniques. Based in Japan, Okuya has established himself at the forefront of adopting and evaluating emerging robotic surgical platforms, particularly for colon and rectal cancer procedures. His most celebrated contributions include the world-first case reports of both right hemicolectomy for ascending colon cancer and low anterior resection for rectal cancer using the hinotori™ Surgical Robot System — groundbreaking achievements that have each garnered nearly 30 citations since their 2023 publication. These reports were instrumental in demonstrating the clinical viability of Japan's domestically developed surgical robot following its 2022 regulatory approval for colorectal surgery. Okuya has continued expanding the frontier of robotic colorectal surgery, documenting Japan's first application of the da Vinci SP single-port system for right hemicolectomy and pioneering hybrid robotic transanal total mesorectal excision approaches. His nationwide retrospective cohort study on robotic inguinal hernia repair further reflects his commitment to evidence-based evaluation of minimally invasive techniques. Through a consistent record of first-in-Japan and world-first surgical innovations, Okuya's work is shaping the evolution of robotic surgery adoption and standardization across Japanese surgical practice.
