title: Left hepatectomy accompanied by a resection of the whole caudate lobe using the dorsally fixed liver-hanging maneuver.
abstract: A resection of the caudate lobe often needs to be combined with a hemi-hepatectomy for hilar cholangiocarcinoma or a liver tumor in segment 1. To achieve complete resection of the whole caudate lobe, the cut line between the right edge of the paracaval portion and the right lateral sector should be precisely controlled. The liver-hanging maneuver (LHM) is a useful anterior approach that does not require mobilization of the remnant liver. However, the precise set-up of the cut line of the right edge has not been optimized in previous reports. We herein introduce a new modification of LHM that we named the "dorsally fixed liver-hanging maneuver" (DF-LHM) based on the results in five patients who underwent left hepatectomy combined with a 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. The DF-LHM may represent a new key technique for this type of hepatectomy, and further applications for other anatomical resections can be modeled on the strategy.
