The sheer number of barriers, just the final one alone, keeps many from attempting laparoscopic liver surgery. Such a result is not surprising since liver surgeries in open procedures are likewise extremely challenging.
The difficulty of liver surgery is such that disrupting blood flow to the liver can cause irreversible damage. The dream of every hepatobiliary surgeon is to perform tumor resections without interrupting blood flow or causing blood loss. To them, it might sound like a fantasy, but surgeons have been tirelessly seeking the perfect solution, even trying methods such as extracting the entire liver like in liver transplantation then performing hypothermic perfusion before removing the tumor.
Research to date has shown that no liver surgery technique has achieved perfection. This illustrates just how difficult the liver is for surgeons to handle.
Today's surgery, being performed laparoscopically, must have its unique features.
