title: [Technique of Mesohepatectomy].
abstract: In patients with primary or secondary malignant central liver tumours, the standard surgical procedure is extended left or right hemihepatectomy. Since extended resections are associated with increased morbidity and mortality and a loss of a large amount of functional liver parenchyma, central liver resection or mesohepatectomy (resection of segments 4a/4b, 5 and 8) with or without the resection of segment 1 is an alternative procedure, although technically demanding and not widely used so far. Resection margins are to the right of the falciform ligament and at the border between segments 5/6 and 7/8, which can be difficult to differentiate. Intraoperative sonography is highly recommended. The current video shows the technique of mesohepatectomy under exclusion of segment 1 in a case of a central colorectal liver metastasis.
