About

Kei Asukai is a pioneering surgeon whose work sits at the intersection of advanced robotics and complex oncologic surgery, with a primary focus on gastric cancer. His most cited research, a 2022 study on robotic total gastrectomy with thrombectomy and portal vein reconstruction, addresses one of the most challenging scenarios in gastric cancer: the presence of a portal vein tumor thrombus (PVTT), which carries a notoriously poor prognosis. Asukai’s major contribution lies in demonstrating that a completely robotic approach can replace highly invasive traditional laparotomy for this life-threatening condition, offering a minimally invasive yet radical solution. By detailing the technical nuances of this combined procedure—including thrombectomy and portal vein reconstruction—he has expanded the boundaries of what is achievable with robotic surgery. Though his citation count is still growing, this work has already garnered 10 citations, signaling its significance in the surgical oncology community. Asukai’s research not only provides a technical roadmap for other surgeons but also offers renewed hope for patients with advanced gastric cancer, marking him as an emerging leader in robotic surgical innovation.
