Intraoperative ultrasound in patients with hepatocellular carcinoma: from daily practice to future trends
No full textStarting from the end of the 1970s, intraoperative ultrasound was introduced and developed to stage liver disease and guide the surgical interventions in patients with hepatocellular carcinoma. Without intraoperative ultrasound, it would probably be impossible to correctly define the hepatic segments as well as the limits of a tumor, also because of the existing wide variations in the anatomy. More importantly, intraoperative ultrasound allows for three-dimensional reconstruction of the relationships between the tumor, hepatic veins, and Glissonian pedicles. Such reconstruction is essential for planning the surgical strategy, which should be individualized in each patient with the aim to spare functional liver parenchyma. This work focuses on the role of intraoperative ultrasound to stage liver disease and to plan surgical resection, describing the most recent technical achievements
[Surgical treatment of liver metastases from colorectal carcinoma]
No full textIn patients with colorectal liver metastases, hepatic resection is the treatment of choice, and the 5-year overall survival rate after surgery is now approaching 60%. The multidisciplinary and multimodality approaches that may include preoperative systemic chemotherapy, and the recent innovative surgical techniques that may include complex ultrasound guided hepatic resection, have enabled a large proportion of patients to undergo potentially curative treatment. The definition of resectability has shifted from a focus on tumor characteristics, such as tumor number and size, to determination whether both intrahepatic and extrahepatic disease can be completely resected, and whether such an approach is appropriate from an oncological standpoint. Hepatobiliary surgeons and medical oncologists should work together to evaluate patients with colorectal liver metastases to individualize the treatment strategy to maximize the chances of long-term survival
