title: Hepatic resection through an anterior approach employing a modified liver hanging maneuver in patients with a massive liver tumor severely oppressing the inferior vena cava.
abstract: For a large hepatic neoplasm existing in the right hepatic lobe, hepatic resection using an anterior approach is required. We have reported an operative procedure for hepatic transection using absorbable polyglycolic acid tape. In patients with suspected tumor invasion of the inferior vena cava, on the other hand, considering the range of the residual tumor while sparing the inferior vena cava as much as possible, combined resection and reconstruction of the inferior vena cava is conducted only if operative curativity is expected. We conducted hepatic transection while maintaining the blood flow of the residual liver by applying the liver hanging maneuver method of Belghiti et al. and polyglycolic acid tape in patients with giant liver tumors of the right hepatic lobe compressing the hepatic inferior vena cava. Strong angled dissecting forceps were inserted into the ventral side of the inferior vena cava from the caudal side, and the tip was induced between hepatic veins. Two strips of polyglycolic acid tape were pinched with forceps and strongly ligated on the right and left sides of the cutoff line. Subsequently, hepatic transection was conducted using electrocautery spray coagulation and CUSA without blocking the inflow blood of the residual liver, and the right hepatic lobe was extirpated. This procedure has already been performed in 5 patients suspected of inferior vena cava invasion, and the inferior vena cava was able to be preserved in all the patients.
