Figure 3. Intraoperative findings. (A): Before the liver transection, minimum adhesiolysis was performed around the area of segment 4 of the liver. Intraoperative ultrasonography was used to demonstrate the locations of the tumors and the line of the umbilical plate, which were marked. (B): The liver parenchymal transection was commenced along a line to the right side of the umbilical plate.

(D): After dividing the branches to subsegments 4a and 4b, the area containing the hepatocellular carcinomas was clearly recognized as an ischemic area, prior to resection
