About
Dr. Shigeo Hisamori is a pioneering surgeon at the forefront of robotic gastrointestinal oncology, whose work is systematically redefining the standard of care for gastric and esophageal cancers. His research centers on the comparative effectiveness and safety of robotic-assisted surgery versus conventional laparoscopic and open approaches. Dr. Hisamori’s major contributions include providing robust, multi-institutional evidence that robotic gastrectomy for gastric cancer yields superior short-term outcomes, such as reduced postoperative pulmonary complications, as demonstrated in his highly cited 2020 study on esophagectomy (59 citations). He has also been instrumental in establishing the feasibility and safety of specific robotic techniques, including the use of monopolar devices, and in rigorously evaluating the learning curve for these complex procedures. With a cumulative impact of over 250 citations, his work has directly influenced clinical guidelines and surgical practice. Notably, his 2023 systematic review (63 citations) and his 2022 multi-institutional comparative study on three-year outcomes (42 citations) provide the highest level of evidence supporting the oncologic and safety equivalence of robotic surgery. Most recently, Dr. Hisamori has extended his expertise to colorectal surgery, demonstrating the feasibility of total proctocolectomy using the novel Hugo RAS system, showcasing his role as a leader in adopting and validating next-generation surgical platforms.
