Hepatectomy using a combination of extrafascial extrahepatic (Takasaki approach) and extrafascial intrahepatic pedicle approaches (Ton That Tung approach)

Abstract

Abstract Selective pedicle control and anatomical liver resection are considered standard techniques in hepatectomy for hepatocellular carcinoma. In 1963, Ton That Tung made significant improvements in hepatectomy techniques with the principle of locating and ligation of Glissonean pedicle in the liver parenchyma based on precise knowledge of vascular and biliary anatomy (Tung TT, Quang ND. A new technique for operating on the liver. Lancet 1963;281:192–3). In 1986, the extrafascial Glissonean dissection was first introduced by Takasaki in 1986. This is a simple and safe technique that helps to identify the exact borders between liver sections for anatomic liver resection (Takasaki K. Glissonean pedicle transection method for hepatic resection: a new concept of liver segmentation. J Hepatobiliary Pancreat Surg 1998;5:286–91). The combination of two techniques helps minimize complications, reduce ischemic time of future liver remnant, intraoperative blood loss and avoid migration of cancer cells into other segments.
