A "cui prodest" evaluation on the development of a minimally invasive liver surgery program: a differential benefit analysis of open and laparoscopic approach for left and right hemihepatectomies.

While MILS is associated with improved clinical outcomes both in left and right hepatectomy procedures, the greater advantage provided by laparoscopy was documented in patients undergoing right hepatectomy, i.e. for more technically demanding procedures. A MILS program should include the broadest range of liver resections to ensure the full benefits of the laparoscopic technique.
