Abstract: The conventional liver anatomy is the theoretical basis of the current techniques for resection of liver malignant neoplasms. With the deepening understanding of liver anatomy, the proposal of liver dynamic watershed theory has transformed the liver anatomy method from the traditional static trunk type to the dynamic watershed type. Under the guidance of dynamic liver blood watershed theory, the author proposes the target-territory resection techniques for liver malignant neoplasms, which is different from anatomical or non-anatomical liver resection and does not emphasize the resection according to the artificially preset liver segments. Instead, it takes the lesion and possible infiltration and metastasis watershed as the guide to determine the target-territory for resection by combining the biological characteristics of liver malignant neoplasms.
