MOTTO:MOTTO:

“Extra-fascial control of the pedicles has been a definite progress and has simplified

considerably sectorectomies and segmentectomies”

Couinaud C., 1989

MOTTO:

Glissonean pedicle transection method prevented intraoperative metastasis and significantly

improved the postoperative survival in patients with hepatocellular carcinoma.
