Background: Radiofrequency ablation (RF) is emerging as new therapeutic method for the management of hepatic tumors. So far the RF-assisted hepatectomy has been described using an electrode initially designed for ablation of unresectable tumors. Herein, we describe a new technique for liver resection using a bipolar radiofrequency device. Method: Ten patients undergo liver resection using a bipolar radiofrequency device. A minimal zone of desiccation around the tumor is created between pairs of opposing electrodes as a result of a minimum amount of energy released. This coagulated plane can be divided with a scalpel. Results: The liver parenchyma was divided with minimal blood loss. No intensive care unit admission was needed. There was no postoperative biliary leak or any other septic complication. Conclusion: The technique is safe and feasible, simplifies liver resection and appears to be associated with minimal morbidity and maximum liver parenchyma preservation.
