[Vasculature based segmental resection of the liver].

Complete surgical resection represents the only treatment for malignant tumors of the liver which offers the chance of long-term tumor-free survival. From this oncological perspective the segment orientated approach appears to be a valuable supplement of traditional hepatic surgery. It minimizes incomplete tumour removal, and prevents a waste of non-involved hepatic tissue. This combination of optimum local radicality and maximum parenchyma preservation also reduces operative risk. Various modern diagnostic and surgical aids such as intraoperative ultrasound, liver transection using the ultrasonic aspirator, and control of bleeding by means of infrared coagulation or fibrin tissue adhesive, all do considerably support this individualized surgical approach. However, the practical application is essentially based on the intrahepatic vasculature and the thereby defined segmental anatomy. The sequence of the operative proceeding will be illustrated for different mono- and polysegmentectomies.
