[Major hepatectomies in liver neoplasms]

The development of major hepatic resective surgery during the last 50 years is due to a better knowledge of both hepatic regenerative capacity and intraparenchymal vascular and biliary anatomy. Two approaches of major hepatic resection have been described: 1) primary hilar approach; 2) primary transparenchymal approach. The authors review the indications of major hepatic resections in the treatment of hepatic tumors and discuss the advantages and the disadvantages of primary hilar and primary transparenchymal approaches, reviewing the data from the literature and the experience gained at the Clinica Chirurgica of the University of Verona from 1970 to 1989 of 289 major hepatic resections.
