About
Dr. Koki Otsuka is a pioneering surgeon advancing the frontiers of minimally invasive gastrointestinal oncology, with a specialized focus on robotic colorectal and pancreatic surgery. His most impactful work critically evaluates emerging robotic platforms, particularly the hinotori™ surgical system, demonstrating its non-inferiority to the established da Vinci system in rectal surgery while uncovering a significant advantage: a marked reduction in subcutaneous emphysema following colorectal cancer procedures. These comparative studies, each garnering 8 citations, provide crucial evidence for hospitals considering new robotic investments. Dr. Otsuka’s research extends beyond technology assessment to health equity; his nationwide analysis of Japanese surgical outcomes reveals troubling disparities linked to regional and patient characteristics, advocating for more uniform access to advanced care. He has also contributed to the high-stakes field of pancreatic surgery, evaluating robotic pancreaticoduodenectomy against open and laparoscopic approaches in a large cohort. Through his work, Dr. Otsuka is not only validating next-generation surgical tools but also championing safer, more equitable cancer care across Japan.
