Glissonian approach combined with major hepatic vein first for laparoscopic anatomic hepatectomy.

Background: Laparoscopic anatomic hepatectomy remains challenging because of the complex interior structures of the liver. Our novel strategy includes the Glissonian approach and the major hepatic vein first, which serves to define the external and internal landmarks for laparoscopic anatomic hepatectomy.

Methods: Eleven cases underwent laparoscopic anatomic hepatectomy, including three right hepatectomies, three left hepatectomies, three right posterior hepatectomies, and two mesohepatectomies. The Glissonian approach was used to transect the hepatic pedicles as external demarcation. The major hepatic vein near the hepatic portal was exposed and served as the internal landmark for parenchymal transection. The liver parenchyma below and above the major hepatic vein was transected along the major hepatic vein. Fifty-nine subjects were used to compare the distance between the major hepatic vein and secondary Glisson pedicles among different liver diseases.

Results: The average operative time was 327 min with an estimated blood loss of 554.55 mL. Only two patients received three units of packed red blood cells. The others recovered normally and were discharged on postoperative day 7. The distance between right posterior Glissonian pedicle and right hepatic vein was shorter in the patients with cirrhosis than that without cirrhosis, and this distance was even shorter in patients with hepatocellular carcinoma.

Conclusion: The Glissonian approach with the major hepatic vein first is easy and feasible for laparoscopic anatomic hepatectomy, especially in patients with hepatocellular carcinoma and cirrhosis.
