A new technical aspect of ultrasound-guided liver surgery

Abstract

Nowadays, resective hepatic surgery should be considered an echo-guided surgical procedure to guarantee that effective anatomical resection is accomplished. We describe a simple and original technique guided by intraoperative ultrasonography (IOUS), called the hooking technique, that enables the ligation sites of the intrahepatic vessels during systematic segmentectomy to be chosen precisely. Together with other IOUS-guided techniques described previously, the hooking technique provides a further guarantee for the successful execution of anatomical and radical liver resection.
