Background:
Since the development of liver surgery, several descriptions of liver anatomical division and hepatectomies have been made, causing some confusion among surgeons.
Methods:
The initial anatomical description according to Couinaud is reviewed and corrected taking into account the descriptions made in the following decades.
Results:
It seems that by reviewing the description of the different authors, a precise anatomical division of the liver may be achieved and a simple terminology of hepatectomies may be proposed.
Conclusions:
It is hoped that the proposal of this anatomical description and this terminology of hepatectomies may find a consensus among the liver surgical community from America, Asia, and Europe.
