Twelve patients in the RH group are also included in the UASH group. Values are expressed as median (range). Major resection: hemihepatectomy, central bisectionectomy, right posterior sectorectomy, right anterior sectorectomy and left median sectorectomy. Anatomical resection: the procedures in which the Glissonian pedicle was divided at the root in bifurcation and all the parenchyma related to the pedicle was resected. LH: Laparoscopic hepatectomy; NH: No history of upper abdominal surgery; RH: Repeat hepatectomy; UASH: Upper abdominal surgery history.
