Major hepatectomy using the glissonean approach in cases of right umbilical portion

Figure 3 Case 2 enhanced computed tomography. A and B: CT shows the right posterior portal branch to be solely bifurcated, and the right anterior and medial segmental portal branches ramify from the RUP; B: A 25-mm sized mass (arrow head) is adjacent to the RUP. The RUP is almost occluded, and the intrahepatic distal bile duct is dilated (B); C: Diagram of the intrahepatic portal vein branching and the location of the tumour. RL: Round ligament; G: Gallbladder; A: Right anterior branch of the Glissonean pedicle; P: Right posterior branch of the Glissonean pedicle; M: Left medial branch of the Glissonean pedicle; RUP: Right umbilical portion; L: Left lateral branch of the Glissonean pedicle; T: Tumour; RHV: Right hepatic vein.
