About
Koichi Yagi is a pioneering surgeon whose research focuses on advancing minimally invasive techniques for esophageal cancer treatment, particularly through robot-assisted transmediastinal esophagectomy (RATME). His major contribution lies in developing and validating a nontransthoracic approach that reduces pulmonary complications and postoperative mortality associated with conventional transthoracic esophagectomy (TTE), while maintaining radical mediastinal lymphadenectomy. Yagi’s landmark 2015 study (81 citations) demonstrated superior short-term outcomes for robotic radical esophagectomy compared to TTE, establishing a less invasive alternative. He further substantiated this through prospective comparisons (2021, 10 citations) showing lower surgical invasiveness via serum cytokine levels and respiratory function. Notably, his work on health-related quality of life (2018, 30 citations; 2019, 39 citations) revealed that patients undergoing RATME experience better long-term QOL, addressing a critical gap in esophageal cancer survivorship. Most recently, his 2025 study (6 citations) provided encouraging survival outcomes for esophageal squamous cell carcinoma patients treated with RATME, solidifying its oncologic efficacy. Yagi’s research has reshaped surgical paradigms, offering esophageal cancer patients a safer, less invasive option without compromising survival.
