Laparoscopic application of the hooking technique for ultrasound-guided minimally invasive liver surgery

Laparoscopic liver surgery has a wide diffusion worldwide, but the reproducibility of a parenchyma-sparing approach with a minimally invasive technique is still to explore. Intraoperative ultrasound (IOUS) is a mandatory tool to guarantee safety (transection plane) and oncological adequacy (margin) of minor but complex resections for deep-located tumors. The hooking technique has been developed exactly with this aim: once a vessel is isolated...
