Researchers from Brussels, Belgium, evaluated the feasibility of utilizing a robot in laparoscopic surgery.
The first robot-assisted procedure in humans was performed in March 1997 by the team, which is based at the Department of Digestive Surgery, Centre Hospitalier Universitaire Saint-Pierre.
The robot (Da Vinci system, Intuitive Surgical, Mountain View, CA), consists of a console and a cart with 3 articulated robot arms.
The surgeon sits in front of the console, manipulating joystick-like handles, while observing the operative field through binoculars that provide a three-dimensional picture.
The computer is capable of modulating data by eliminating physiologic tremor and by downscaling the amplitude of motions by a factor of 5 or 3 to one.
|17 different types of robotic laparoscopic procedures were performed.

A total of 146 patients have undergone robot-assisted laparoscopic surgery at the institution since the first procedure was conducted.
The procedures performed included 39 antireflux operations, 48 cholecystectomies, 28 tubal reanastomoses, and 10 gastroplasties for obesity. Thirteen other types of operation were also conducted.
The researchers found that there was no morbidity related to the system.
Operating time and the hospital stay were within acceptable limits.
Dr Guy-Bernard Cadière said on behalf of his colleagues, "The system seems most beneficial in intra-abdominal microsurgery, or for manipulations in a very small space.
"Optimized ergonomics and increased mobility of the instrument tips are beneficial in many steps of abdominal surgical procedures."
"This study has demonstrated the feasibility of several laparoscopic robotic procedures," he concluded.
