Robotic surgery has many advantages, such as less blood loss and improved visibility. Many believe the long term outcomes to be better but the science behind that assumption is only now materializing. Using a large cancer registry, Hu et al have recently published a study looking at over 13,000 men and concluded that robotic surgery is, in fact, superior to open surgery. Patients undergoing robotic surgery were less likely to need second line cancer treatments than patients undergoing open surgery.
This study gels with my own personal experience. As one of the few Urologists equally trained in robotic and open surgery, my robotic outcomes have now outpaced my open outcomes. Because of these improved outcomes, I now perform robotic surgery almost exclusively. With the recent release of the latest daVinci Xi robot (which I just sat down for a test run today) we should continue to see improved outcomes as this technology continues to rapidly advance.
