About

Dr. Koshiro Ishiyama is a pioneering surgeon at the forefront of integrating artificial intelligence with robotic surgery for esophageal cancer. His research focuses on advanced minimally invasive esophagectomy techniques, particularly the use of robotic systems to improve surgical precision and patient outcomes. Dr. Ishiyama’s major contributions include demonstrating the feasibility of a four-armed robotic approach for total mediastinal lymphadenectomy (RETML-4), a prospective study that has garnered 17 citations. He has also shown that robotic esophagectomy is technically feasible and oncologically effective for locally advanced T3/T4 tumors, outperforming conventional thoracoscopic methods in a propensity-matched analysis (10 citations). Most notably, Dr. Ishiyama is a leader in applying artificial intelligence to enhance intraoperative safety. His 2024 study on an AI model for recognizing the recurrent laryngeal nerve during robot-assisted esophagectomy (23 citations) represents a breakthrough in preventing vocal cord paralysis. His subsequent 2025 work further explores how AI can optimize the timing of nerve recognition, underscoring his commitment to merging cutting-edge technology with surgical practice to improve patient safety and outcomes.
