This is the case of a 73-year-old man presenting with a 33mm hepatocellular carcinoma arising on a Hepatitis C virus-related well-compensated cirrhosis without portal hypertension. A laparoscopic segment 7 atypical resection was decided upon. Five ports are placed. The procedure begins with complete abdominal exploration and intraoperative liver ultrasonography. The right triangular and coronary ligaments are divided in order to mobilize the right lobe and gain access to liver segment 7. The hepatic hilum is encircled with an umbilical tape. The tape is passed percutaneously through a 24 French chest tube used as Rommel’s tourniquet to allow for a safe and fast extracorporeal Pringle maneuver. The transection plane is controlled using ultrasound. The first part of parenchymal transection is performed using Thunderbeat™ while an ultrasonic dissector (CUSA™) is used more deeply. Hemostasis is controlled with irrigated bipolar forceps and clips on major vessels. To allow for a bloodless parenchymal transection and a more precise isolation and clipping of the vessels, the hepatic hilum is clamped for 10 minutes. The chest tube is pushed towards the hilum and clamped extracorporeally. After 10 minutes, the Pringle maneuver is released for 5 minutes and then repeated for another 10 minutes until parenchymal transection is complete. No drains are placed. Operative time took 180 minutes and total blood loss was 50mL. The postoperative course was uneventful and the patient was discharged on postoperative day 3. The pathology confirmed a 3cm hepatocellular carcinoma without microvascular invasion. Resection margins were negative for tumor invasion.
