About
Tatsuto Nishigori is a surgical oncologist whose research sits at the forefront of minimally invasive and robotic surgery for gastrointestinal cancers, with particular expertise in esophageal and gastric malignancies. His work has meaningfully advanced the evidence base for robot-assisted techniques, demonstrating through rigorous propensity score-matched analyses and large-scale nationwide registry studies that robotic approaches can reduce postoperative pulmonary complications and improve surgical safety compared to conventional minimally invasive methods. His 2020 study on robot-assisted esophagectomy, now cited 59 times, was among the first to quantify these clinical advantages convincingly, while his nationally representative investigations into robotic gastrectomy in Japan — collectively accumulating over 130 citations — have informed health policy and shaped insurance reimbursement frameworks under Japan's National Health Insurance system. Nishigori has also contributed to understanding the surgical learning curve for robotic gastrectomy and examined three-year oncological outcomes across multiple institutions, lending his findings both clinical and real-world policy relevance. His body of work offers students and clinicians an invaluable evidence-based framework for evaluating the evolving role of robotic surgery in upper gastrointestinal oncology.
