Based on their personal experience in hepatic resective surgery the authors dwell upon details of surgical technique which, well combined and sustained by advanced technological supports (ultrasonic dissector, laser-argon clotter, intraoperative echography), allow to perform wide parenchymal resections sheltered from dangerous complications. The safety achieved in such a surgery--now routinely performed--derives not only from improved diagnostic techniques (US, CT, MNR, angiography) and advances in anaesthesia-reanimation but, above all, from precise knowledge of organon segmental anatomy and close vascular correlations between the two hepatic hemisystems.
