Totally laparoscopic associating simultaneous bile duct and portal vein ligation for planned hepatectomy for primary liver cancer: a case report

Abstract

Background: Some patients with liver cancer lose the chance to have surgical treatment due to insufficient future remnant liver. To address this problem, individual or occlusion of both the portal vein and the bile duct was used to achieve quick hypertrophy. This is the first study reported in which simultaneous ligation of the portal vein and the bile duct was applied as the first step of planned hepatectomy of primary liver cancer. Case presentation: Here we report a case of a 38-year-old Asian male patient with hepatocellular carcinoma with tumor thrombus in the right anterior branch of the portal vein. Right hemihepatectomy can be curative, but patients face a high risk of liver failure because of the small volume of the remaining left liver lobe. Hence we developed a two-step liver resection strategy in which the patient underwent laparoscopic simultaneous bile duct and portal vein ligation of the right hepatic lobe prior to right hemihepatectomy under laparoscopy. Using this procedure, we achieved fast hypertrophy of the left liver lobe and successfully reversed the primary unresectability. Conclusion: This case report demonstrates that simultaneous bile duct and portal vein ligation may be a feasible option for those patients with liver cancer who cannot get surgical treatment due to insufficient future remnant liver.
