Use of robotics during laparoscopic gastric bypass for morbid obesity.

To evaluate the theoretical increased precision offered by utilization of the robotic instrument, we attempted to determine whether incorporation of its use into traditional laparoscopic gastric bypass would duplicate or improve the success of the operation without increasing complications. The Roux-en-Y gastric bypass is the most commonly performed procedure for morbid obesity in the United States. We performed 120 gastric bypass procedures with traditional laparoscopy during a 30-month period. We began introducing the da Vinci Robotic Surgical System into our laparoscopic gastric bypass procedure and evaluated its effectiveness.
