Objective: despite recent advances in medical imaging, pre-operative evaluation of liver tumors, whether benign or malignant, is often lacking in accuracy and precision. With the development of surgical laparoscopy, the benefits of diagnostic laparoscopy have been combined with those of operative ultrasound. This article aims to describe the technique of laparoscopic ultrasound of the liver, and to define its applications and the role of its association with diagnostic laparoscopy in the localization and assessment for resectability of liver tumors. Methods: after an initial visual inspection with the laparoscope, laparoscopic ultrasound is utilized to further examine the liver. This relies largely on recognition of branches of the portal vein and tributaries of the hepatic veins. During this procedure, the hepatic parenchyma is also examined. Minimal displacement of the transducer, using clockwise and anti-clockwise rotatory movements, allows a full exploration of the liver. Results: the combination of visual with sonographic laparoscopy allows accurate localization of benign and malignant hepatic tumors, as well as ultrasound-guided biopsies of these. Laparoscopic ultrasound can detect small lesions previously unseen by pre-operative imaging techniques. The relationship of tumors to adjacent blood vessels can be defined. Portal vein thrombosis can be diagnosed. Conclusion: curability and liver tumor resectability can be determined and the appropriate surgical treatment thus planned.
