About
Sumito Sato is a leading colorectal surgeon whose work centers on advancing minimally invasive techniques for rectal cancer, with a particular focus on robotic-assisted surgery and nerve preservation. His seminal 2014 study on the learning curve for robotic-assisted rectal cancer surgery, cited over 130 times, established critical benchmarks for surgical training by applying the cumulative sum method to quantify proficiency. That same year, his report on 50 consecutive robotic-assisted lateral lymph node dissections (71 citations) demonstrated the feasibility and short-term safety of this technically demanding procedure. More recently, Sato has pioneered efforts to improve functional outcomes, including a 2021 study comparing minimally invasive laparoscopy to open surgery for reducing local recurrence in low rectal cancer. His most innovative work involves using a handheld Raman spectrometer for automated, non-invasive identification of pelvic autonomic nerves during colorectal surgery—a preliminary study that could revolutionize nerve-sparing techniques and reduce postoperative urinary and sexual dysfunction. By combining rigorous outcomes research with cutting-edge technology, Sato continues to shape the future of precision, patient-centered colorectal surgery.
