About

Masafumi Nii is a surgeon-researcher at the forefront of minimally invasive gynecologic oncology, specializing in the optimization of robotic and laparoscopic surgery for complex patient populations. His work centers on refining surgical techniques to improve outcomes in women with endometrial cancer, particularly those with obesity—a group historically at higher risk for surgical complications. Nii’s most influential study, with 16 citations, directly compared laparoscopic versus robotic hysterectomy in obese patients with early-stage endometrial cancer, providing critical data on intraoperative and postoperative outcomes. He further advanced this field by demonstrating that visceral adipose tissue percentage is a superior predictor of surgical outcomes compared to traditional body mass index (BMI), a finding with 10 citations that challenges standard preoperative assessment protocols. Beyond oncology, Nii has contributed to benign gynecologic surgery, comparing robot-assisted and conventional laparoscopic hysterectomy (9 citations), and has innovated in patient safety by evaluating a portable interface pressure sensor to prevent compartment syndrome during robotic procedures. His research is distinguished by its practical, patient-centered focus, directly informing surgical decision-making and safety protocols in gynecologic surgery.
