This is the case of a 68-year-old male patient, affected by hemochromatosis, with 3-cm hepatocellular carcinoma in segment 5 on cirrhotic liver. The patient was classified as Child A5, MELD 7, with portal hypertension (platelet count: 86×109/L). An ultrasound-guided laparoscopic resection of segment 5 was planned.
Surgical technique (Figure 1)
Under general anesthesia, the patient was placed in supine position with the surgeon between the legs. Five trocars were usually inserted. The procedure was performed with pressure-controlled CO2 pneumoperitoneum, maintained at 12 mmHg. The liver was explored visually and by laparoscopic ultrasonography in order to definitely stage the tumor, to evaluate the relationship of the tumor with vascular and biliary pedicles, and to guide the resection. Portal pedicle was encircled with a tape to allow intermittent pedicle clamping if required. Liver resection was carried out by the 80-degree articulating vessel sealer (Aesculap Caiman; B. Braun, Tuttlingen, Germany) and by the ultrasonic dissector (Cavitron Ultrasonic Surgical Aspirator System 200; Valleylab Inc.). Vascular stapler was used to intraparenchymal divide the main branch of the middle hepatic vein and the peripheral portal pedicle to segment 5. The posterior transection plane was easily reached by the 80-degree articulation jaw with lower risk of approaching to the tumor. No blood transfusions were needed. Postoperative course was uneventful. Pathology confirmed the diagnosis of hepatocellular carcinoma. Minimum surgical margin was 1.5 cm.
The use of intraoperative ultrasound during liver resections is fundamental in order to achieve adequate surgical margins (2). However, the risk to progressively advance toward the center of the resection area, especially in case of multiple transection planes, is well known in liver surgery (3), with the consequent risk to expose the tumor on the cut surface. This risk may be increased during laparoscopic liver resection particularly when there is not a unique linear resection line (4). In such cases, by using straight energy devices, it may be difficult to follow a correct posterior transection plane with the risk of approaching to the tumor. This video shows the efficacy of an 80-degree articulating advanced bipolar device (5,6) during liver resection for hepatocellular carcinoma with multiple transection planes. The 80-degree articulation jaw allows a perpendicular seal, which may be useful in case of deep or posterior transection planes to obtain an adequate oncologic surgical margin.
