The claim
“Robot surgery gives better results than regular surgery.”
Better results are not shown in general: a large hernia trial found no recovery benefit at higher cost, and FDA says cancer outcomes are unproven.
01The evidence
Independent
A randomized trial in The BMJ compared robot-assisted with standard keyhole (laparoscopic) repair of abdominal wall hernias and found no difference in days spent in hospital over 90 days.
Independent
The FDA says it has not established that surgical robots are safe and effective for preventing or treating cancer when judged by results such as survival or the cancer coming back.

The FDA says its clearances of surgical robots for some cancer operations rest on 30 days of patient follow-up.

For cervical cancer, the FDA notes limited reports that keyhole surgery, including robot surgery, was linked to lower long-term survival than open surgery; other reports found no significant difference.

The FDA says the benefits of surgical robots may include making keyhole surgery possible and helping with hard tasks in tight spaces in the body.

What we don't know. Results differ by operation, and we could not open the main systematic reviews for specific operations such as prostate or bladder surgery.
