Abstract
In recent years laparoscopic liver surgery has become more popular, thanks to technical refinements and standardization of techniques. Its development relied on the capability to reproduce the same surgical steps of open procedures. Intraoperative liver ultrasonography (IOUS) has a fundamental role in liver surgery to complete disease staging and to guide resection. The same performances have to be expected by
laparoscopic ultrasonography (LUS). In this chapter, the contribution of LUS to laparoscopic liver resection will be briefly analyzed. The disease staging by LUS includes different steps: detection and characterization of known lesions, disclosure of additional nodules, and identification of relationships between lesions and vasculo-biliary structures. LUS may detect new malignant nodules in up to 20–30 % of patients. A direct comparison between open IOUS and LUS demonstrated similar performances by the two procedures. In addition, LUS has several roles during liver surgery: it is the only way to understand the precise liver anatomy and to recognize the presence of vasculo-biliary anomalies; it exactly localizes the lesions; it helps to plan the adequate operation. During resection, especially nonanatomic ones, LUS is fundamental to check the adequacy of transection line and the surgical margin.
