About

Masaaki Andou is a pioneering gynecologic surgeon whose work has redefined the boundaries of minimally invasive surgery, particularly in the management of complex endometriosis and uterine pathology. His research centers on the application of single-port robotic platforms—specifically the da Vinci SP—to perform advanced procedures that were once considered too challenging for minimal-access approaches. Andou’s major contributions include the development and refinement of vaginal-assisted natural orifice translumenal endoscopic surgery (NOTES) hysterectomy for large uteri, a technique that eliminates visible incisions while maintaining safety and efficacy. He has also advanced nerve-sparing eradication of deep endometriosis, preserving pelvic function in patients with severe disease, and pioneered ureteroneocystostomy for ureteral endometriosis using the same single-port system. Though his most-cited papers are recent—with the 2025 NOTES hysterectomy study already accumulating 9 citations—their rapid uptake reflects the field’s hunger for reproducible, scarless solutions. Andou’s work is notable for demonstrating that single-port robotics can match or exceed outcomes of traditional laparoscopy, even in the most anatomically distorted cases. His achievements position him as a key figure in the evolution of gynecologic surgery toward truly scarless, organ-preserving interventions.
