BACKGROUND/PURPOSE: Large liver tumors often expand and severely compress intrahepatic vessels. In cases of the trisectionectomy for such tumors, however, it is difficult to adequately expose the transection planes. The liver hanging maneuver (LHM) is a useful technique for hemihepatectomy and an adequate transection plane might be also required in trisectionectomy. METHODS: LHM procedure is basically followed by the Belghiti's method. A nasogastric tube was used for hanging. At the hepatic hilum, the tube was placed between the liver and Glisson's pedicle. RESULTS: We report here the application of LHM for right and left trisectionectomy in patients with a large hepatoma in two cases. In case of a right trisectionectomy for a large tumor compressing the umbilical Glisson's pedicle, an adequate transection plane was obtained using the LHM because the resected and remnant livers rotated to the other side upon lifting the tube during transection. In case of a left trisectionectomy for a large hepatic tumor compressing the right hepatic vein, an adequate transection plane along the right hepatic vein was obtained using LHM as well. CONCLUSIONS: LHM is a useful surgical application for right and left trisectionectomy in patients with large liver tumors compressing the cut plane.
