Rouviere Sulcus Plane and Hepatic Hilum Plane, Which is Better as a Landmark in Laparoscopic Bile Duct Surgerys

RS and the RS plane are important anatomical markers in laparoscopic cholecystectomy. However, there are many variations in the shape and orientation of the RS, and the RS plane is an imaginary plane, which can be misjudged by different surgeons. The purpose of this study is to introduce a more intuitive anatomical marker and anatomical plane, hilum plane, and discuss the application value of hilum plane in laparoscopic biliary surgery by comparing it with RS and RS plane.
