After positioning, the operation begins with a standard cholecystectomy. The liver is mobilized and short caudate venous branches to the inferior vena cava are secured with clips and divided. Hilar dissection is focused on the posterior sectoral pedicle. The arterial branch to the posterior sector is isolated and divided. A partial caudate hepatomy is done to expose the bifurcation of the portal venous branches to segment 6 & 7. The portal vein branch to segment 6 is divided with a vascular stapler resulting in a zone of perfusion demarcation. The parenchyma is transected using a bipolar cautery device and vascular stapler. The specimen is removed through a limited umbilical incision.
