About

Misato Sawai is a pioneering surgeon-researcher at the forefront of minimally invasive gastric cancer surgery, with a specialized focus on robotic and laparoscopic techniques. Her most impactful work centers on advancing solo surgery—a paradigm where a single surgeon performs complex procedures without an assistant—demonstrating its feasibility and safety in robot-assisted gastrectomy. In her landmark 2023 study, a propensity score-matched analysis comparing solo robot-assisted gastrectomy to conventional laparoscopic gastrectomy, Sawai provided critical evidence that robotic platforms can reduce operative time and enhance surgical autonomy while maintaining oncologic outcomes. This work, already garnering 13 citations, underscores her role in shaping the next generation of gastric cancer treatment. Sawai’s contributions are particularly notable for addressing the practical challenges of surgical workforce shortages and improving ergonomics for surgeons. By rigorously evaluating outcomes in high-volume centers, she has helped validate robotic solo surgery as a viable alternative to traditional approaches, offering patients reduced trauma and faster recovery. Her research continues to influence clinical guidelines and inspire young surgeons to explore innovative, technology-driven solutions in gastrointestinal oncology.
