What is Minimally Invasive (or Laparoscopic) Surgery?

The term minimally invasive surgery is used to describe abdominal surgery performed without making a large incision though the skin and muscle to open the abdomen. Instead, a scope is inserted though a trochar inserted into the abdomen though a 1/2 inch incision. The abdomen is inflated with CO2 gas to distend it like a tent, allowing visualization of the abdominal organs.

Long hand-held instrument are inserted through smaller trochars and used to perform the surgery, while the surgeon views the inside of the abdomen on a TV screen. Specialized tools such as scissor, graspers, ultrasonic dissectors and endoscopic staplers facilitate the surgeon’s ability to perform complex intraabdominal surgery using advanced laparoscopic techniques.

For more details, see the Minimally Invasive Surgery page.
