About

Ryohei Sasamori is a pioneering thoracic surgeon whose work centers on advancing minimally invasive surgical techniques for esophageal cancer and other esophageal pathologies. His primary research focus is the comparison and optimization of robotic-assisted thoracoscopic esophagectomy (RATE) versus conventional thoracoscopic esophagectomy (TE). In his most cited study (2021, 13 citations), Sasamori demonstrated that RATE achieves a significantly lower local recurrence rate than TE for thoracic esophageal cancer, providing crucial evidence for the oncological superiority of robotic approaches. He has also contributed to expanding the indications for robotic surgery, including a case report (10 citations) detailing the successful robot-assisted enucleation of a large esophageal leiomyoma—a technically challenging procedure due to tumor size and location. Further showcasing his expertise, Sasamori reported a salvage robotic-assisted thoracoscopic esophagectomy following definitive chemoradiotherapy for cT4b esophageal cancer (3 citations), highlighting the potential of robotics in complex, high-risk salvage settings. Through these contributions, Sasamori is helping to define the evolving role of robotic surgery in improving outcomes for patients with challenging esophageal conditions.
