About

Dr. Hitoshi Ojima is a pioneering colorectal surgeon whose work is redefining the role of robotics in gastrointestinal oncology. His primary research focuses on optimizing robotic surgical techniques for complex cancers, with a particular emphasis on rectal cancer management. Dr. Ojima’s major contributions include demonstrating the safety and feasibility of robotic-assisted abdominoperineal resection (APR) while actively seeking to overcome its traditional drawbacks of longer operative times and higher costs. He has rigorously analyzed the learning curve for robotic bedside assistance using the cumulative sum method, providing essential benchmarks for training the next generation of surgeons. His innovative work extends to tackling the rising challenge of multiple primary malignancies, as seen in his studies on simultaneous robotic resection for gastric and rectal cancers. Demonstrating a holistic view of surgical well-being, Dr. Ojima has also explored the use of wearable technology, like the Apple Watch, to monitor surgeon stress and heart rate during operations. With his most cited paper garnering 8 citations and a growing body of influential work, Dr. Ojima is a key figure advancing both the technical precision and the human factors of modern robotic surgery.
