Robotic liver resection is safe and shows better outcomes as surgeons gain experience.

• Operative time decreases significantly after 62 cases, from 240 to 220 minutes.
• Progress to mastery increases textbook outcomes from 76% to 87%.

High complexity cases still meet benchmark standards, indicating robust performance.

• Major complications plateau at 9% during proficiency, with low conversion rates (2%) and stable 90-day mortality (0.7%).
