Diagram of hepatic parenchymal transection process. Site A indicates the starting point of the parenchymal dissection. Step 1. Hepatic resection is begun at Site A and continued further cranially along the MHV; and the trunk of the MHV was also exposed; Step 2. Next, the hepatic resection was continued from the Site A toward the right direction of caudal side transection plane; the G8 was exposed and divided; Step 3. Subsequently, the liver parenchyma between S8 and S7 was dissected along the RHV and ischemic line from the root side to the peripheral side; with this, transections finished. In order to full exposure, Step 1 and Step 2 are continued alternately according to the intraoperative situation
