Abstract    Hepatectomy is a major theme of dealing with all kinds of benign and malignant tumors of liver. Conventional finger fracture and clamp crushing methods, with many shortcomings such as poor exposure of intrahepatic vessels and insufficient control of bleeding, are more likely to cause postoperative hemorrhage, bile leakage, postoperative infection and so on. Recently, with the progress of science and technology, liver excision rate can be as high as 40% and operation related mortality is only 5% that owe a lot to the application of new liver resection technologies, such as high frequency surgical unit, ultrosonic-harmonic scalpel(UHS), ligasure vessel sealing system(LVSS), cavitron ultrasonic surgical aspirator(CUSA), TissueLink, water jet dissector and so on. However, each of these liver resection technologies that have been applied to clinical practice has its own advantage and disadvantage, so surgeons still need to choose the right one based on their experiences, equipment conditions and their demands for the degree of accurate dissection in the operation.
