This is the case of a 72-year-old woman presenting with a 5cm intrahepatic cholangiocarcinoma arising on an HCV-related well-compensated chronic liver disease without portal hypertension. Laparoscopic left hepatectomy (liver segments 2, 3, and 4) was decided upon. Four ports were placed. The procedure began with a complete abdominal exploration and intraoperative liver ultrasonography, which allowed to identify the tumor between liver segments 2 and 4a in close contact with the left hepatic vein. Hilar dissection was performed with lymphadenectomy of the common hepatic artery and left hepatic artery. Before parenchymal transection, both inflow and outflow of the left liver were interrupted. The left hepatic artery and the left portal vein were isolated and divided between clips. The left hepatic vein was isolated after division of the Arantius’ ligament and clamped by means of a laparoscopic vascular clamp. Parenchymal transection was carried out using an ultrasonic dissector (CUSA™), and hemostasis was controlled with a radiofrequency bipolar hemostatic sealer (Aquamantys™) and clips. The biliary duct and the left hepatic vein were managed with vascular staplers. At the end of the operation, a tubular drain was placed. Operative time accounted for 240 minutes and total blood loss was 100mL. The postoperative course was uneventful and the patient was discharged on postoperative day 6. The pathology confirmed a 5cm G3 cholangiocarcinoma with invasion of the left hepatic vein and of segment 2 portal branch. Resection margins were negative for tumor invasion and for all lymph nodes retrieved.
