RFA is a safe and effective procedure for treating patients with malignant liver tumours. No difference in short term outcomes was observed between percutaneous and surgical approaches. A more prolonged follow-up study is required to assess longer-term outcomes.
As a safer approach to right hepatectomy, Belghiti et al. (J Am Coll Surg 193:109-11, 2001) described a liver-hanging maneuver. However, this procedure is performed blind, with the risks of damaging the small retrohepatic veins and consequential bleeding. To overcome this problem, we modified the procedure so that, instead of performing blind dissection using a long vascular clamp, we use a flexible choledochoscope to dissect the retrohepatic space filled by loose alveolar tissue anterior to the inferior vena cava (IVC). The avascular path is identified by a combination of saline irrigation and gentle movement of the tip of the choledochoscope. Cotton tape can then be passed around the liver parenchyma to elevate the liver away from the anterior surface of the IVC. This modification of Belghiti's liver-hanging maneuver allows direct vision along the plane anterior to the IVC, thus avoiding injury to the retrohepatic veins.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
