A laparoscopic right hemihepatectomy was performed for a gastric liver metastasis. After the dissection of the anatomical structure of the hepatic pedicle and an ultrasound examination, the right portal vein and the right branch of the hepatic artery were clamped, hence allowing to skeletonize the demarcation between the right liver and the left liver. The devascularization line was subsequently marked by means of electrocautery. The right hepatic branch and the right branch of the portal vein were divided between locked clips. The hepatotomy was started. The first very superficial centimeters were dissected using the Sonicision® Cordless Ultrasonic Dissection Device. No pedicular clamping was performed. The dissection followed the ischemic demarcation line between the right liver and the left liver. Hemostasis and biliostasis were completed using the Aquamantys® Bipolar Sealers. Once the first centimeters had been dissected, dissection was carried on using the CUSA™ ultrasonic dissector (Cavitron Ultrasonic Surgical Aspirator). Liver segment I was divided in order to open the posterior aspect of the hilar plate. The dissection was performed on the right border of the vena cava. The hilar plate was dissected, making it possible to control the right branch of the biliary tract intraparenchymally. The right hepatic vein was dissected and divided with an Endo GIA™ linear stapler. Makuuchi’s ligament was subsequently dissected and divided by means of a firing of the Endo GIA™ linear stapler, white cartridge. Mobilization of the right liver was completed by dividing the triangular ligament’s attachments at the level of the diaphragm. The right hepatectomy specimen was introduced into a bag, which was extracted through a suprapubic Pfannenstiel’s incision. Pneumoperitoneum pressure was diminished in order to control hemostasis and biliostasis.
