title: [Hemihepatectomy].
abstract: Hemihepatectomy continues to be a standard procedure for the resection of primary or secondary liver tumours in hepatobiliary surgery. In this tutorial, a case study illustrates the indication for liver resection as well as surgical steps and different techniques. Indications for right or left hemihepatectomy include liver tumours that cause a diffuse or extended infiltration of one half of the liver or tumours extending to the central confluence of liver veins or the liver hilum. Usually, a resection limit is only required in the case of extended hemihepatectomies, where a two-stage resection is needed. In addition to exploration and intraoperative ultrasound, this tutorial presents different entry sites, liver mobilisation, hilum preparation and common techniques of parenchymal dissection. Finally, a number of haemostasis, closure and biliary monitoring techniques are shown. The video tutorial demonstrates all fundamental steps of hemihepatectomy from indication to closure, with a special focus on different approaches.
