About

Kazuo Koyanagi is a leading surgical oncologist whose research is reshaping the treatment of esophageal and colorectal cancers through the integration of advanced technology and precision surgery. His primary focus is on minimally invasive esophagectomy (MIE) and robot-assisted techniques, where he has made landmark contributions. Notably, his highly cited 2020 study on postoperative complications of MIE (61 citations) provided the first comprehensive characterization of risks in this increasingly common procedure, establishing a critical benchmark for surgical safety. Dr. Koyanagi is at the forefront of applying artificial intelligence to surgery; his pioneering 2024 work demonstrated an AI model’s ability to recognize the recurrent laryngeal nerve during robot-assisted esophagectomy (23 citations), a breakthrough that promises to reduce vocal cord paralysis. His 2025 follow-up further refined this AI timing, while his research on perioperative skeletal muscle loss in colorectal cancer patients (2024) highlights his commitment to holistic patient outcomes. By merging AI with surgical precision, Dr. Koyanagi is not only improving operative safety but also defining the future of oncologic surgery.
