OBJECTIVE: To analyze the feasibility of developing a tunnel between inferior vena cava (IVC) and caudate lobe before passing a tape through it, and to explore the significance of liver hanging maneuver in liver-splitting anterior approach for hepatectomy. METHODS: Blunt dissection was used to develop the tunnel before a tape was passed through. A hemostatic plate was placed on the surface of liver parenchyma if needed. In the procedure of hepatectomy, the tape was pulled up to create an interspace between liver parenchyma and IVC so that the IVC can be protected during transection. RESULTS: Liver hanging maneuver was performed successfully in 47 cases. There were no severe complications related to the procedure in these cases. The procedure was terminated in 1 case because of severe bleeding. CONCLUSIONS: 1. Liver hanging maneuver is feasible in terms of anatomy and technique. 2. With liver hanging maneuver, IVC can be protected safely and the intrahepatic vessels and ductal system at the transaction line can be exposed clearly. It also makes anterior approach for hepatectomy safer and easier.
