The main objective of minimally invasive surgery procedures is to reduce the trauma and the inflammatory response associated with open invasive surgery. Robotics, laparoscopic devices and endoscopes are used in such procedures to assist manipulation of the surgical devices and to view the surgical field. The operative time with minimally invasive surgery is often longer but the hospital stay is typically shorter as compared to open invasive surgery.
