Abstract.Resection of the caudate lobe needs to be combined with hemi-hepatectomy for hilar cholangiocarcinoma or liver tumor in segment 1. To achieve complete resection of the whole caudate lobe, the cut-line between the right edge of paracaval portion and right lateral sector should be controlled. The liver-hanging maneuver (LHM) is useful for anterior approach without mobilization of the remnant liver. The precise set up of cut-line of the right edge was not indicated by previous reports yet. We herein introduce a new modification of LHM named "dorsally fixed liver-hanging maneuver" (DF-LHM) by the results in 5 patients who underwent left hepatectomy combined total resection of segment 1. This technique provided adequate cut planes along the right edge of the caudate lobe, shortening the transection time and reducing intraoperative blood loss. DF-LHM can be a key technique for this hepatectomy and further applications to other anatomical resections can be expected.
