LAPAROSCOPY IN UROLOGY : (R)EVOLUTIONS IN TRAINING AND SURGERY

Mechanicale damage and trauma of the gastro-intestinal tract can occor in laparoscopic and robot-assisted surgery (so-called minimally invasive surgery). Usually this drama unfolds outside the operative field and thus outside of the surgeon's view. This explains why this complication can be missed during surgery , with sepsis and death as potential outcome.This research shows that microscopic damage of biologic tissue can be detected before it becomes apparant macroscopicaly. This can be done by measuring the force and position of the instruments that hold the biologic tissue during surgery. If the exerted force drops without displacement, microscopy reveals tearpoints in the manipulated tissue. In the rat model, the safety range for manipulation bowel lies between 0,7 and 1,2 Newton.If this phenomenom occurs, a warning can be given to the surgeon. A more stringent alternative is the implementation of safety margins that can only be exceeded with a direct command. This is comparable to overruling the cruise control on your car when and emergency occurs and more speed is needed by pushing the accelerator.
