Highlight
Early adoption of robot-assisted surgery shows substantial sex disparities in operative opportunities among gastroenterological surgeons in Japan.
Female surgeons perform a markedly lower proportion of robot-assisted distal gastrectomies and low anterior resections compared to male surgeons.
Operative volume for robot-assisted procedures increases with experience for male surgeons but not for females, with disparities emerging approximately 10 years after medical registration.
These inequities may contribute to persistent sex-based career differences in surgery.
