Application of the robot for Roux-en-Y gastric bypass has been slow to evolve, despite its rapid acceptance in other fields. This is largely due to associated costs of technology, reports of increased operative time, and inadequate data available to correlate the benefits of robotics to a clinical outcome. The authors present a comparative study between laparoscopic and robot-assisted Roux-en-Y gastric bypass performed at a specialized institution for robotic surgery.
