I’m a strong believer in laparoscopic and robotic surgery for a single, simple reason. It’s better for the patient. Minimally invasive surgery, a catch-all term which includes laparoscopy, hysteroscopy, and robot-assisted surgery, has proven benefits.
The benefits of minimally invasive surgery, compared to conventional “open” surgery include:
• less post-operative pain
• reduced need for pain medication
• faster return of normal appetite and bowel function
• smaller incisions
• less scarring
• faster recovery and return to work
Robotic surgery in particular has advantages which allow the surgeon to perform more complex procedures via a laparoscopic approach than might otherwise be possible. The robotic system gives the surgeon the benefits of:
• greater magnification with the laparoscopic camera
• 3 dimensional (3D) vision
• greater range of motion for laparoscopic instruments
• increased comfort, which may reduce a surgeon’s fatigue during long procedures
• reduction of biologic hand tremor
The robot doesn’t bear much resemblance to what we’ve come to expect from science fiction. It doesn’t have artificial intelligence and it cannot operate independently. In fact, the robot is just another instrument. It is controlled by the surgeon who sits at a console next to the patient.
The Da Vinci Robotic Surgical System
The robot has arms whose attachments are miniature versions of conventional surgical instruments (i.e. scissors, clamps, needle and suture-holders). These tiny instruments mimic the surgeon’s movements at the console (but on a much smaller scale). This allows the surgeon to perform surgical procedures with extraordinary precision.
Laparoscopy revolutionized surgery by making many major surgeries into outpatient procedures. Robotic surgery is revolutionizing laparoscopy by broadening the range of surgeries which can be performed with a minimally-invasive approach.
