Separating the Right Segmental Branch

The right segmental branch enters the liver below the recesses just behind the cystic duct. The dissection procedure is the same as that for the middle segmental branch (Fig. 5.28). The small branches leading to the caudate area should be identified. It is essential that dissection be executed distal to these small branches. The borderline between the right lobe and the caudate area is confirmed by the sighting of the caudate process. The branches to the left of the borderline are caudate-area branches and must not be damaged. After the right segmental branch is dissected circumferentially, it is taped (Figs. 5.29, 5.30). Then the right segmental branch is ligated and transected.
