The “Tenting Sign of the Hepatic Vein” Is Important for Laparoscopic Anatomical Hepatectomy Along the Major Hepatic Vein

Background Laparoscopic hepatectomy has rapidly evolved and has become a viable alternative to open hepatectomy. However, the dissection of liver parenchyma via the laparoscopic caudal approach (parenchymal transection from the caudal to cranial direction under a laparoscopic caudal view) has several limitations. To avoid these limitations in anatomical hepatectomy along the hepatic vein with the caudal approach, it is important to recognize the “tenting sign of the hepatic vein,” which helps to identify the running of the main trunk of the hepatic vein.
