AbstractRadiofrequency (RF) ablation is emerging as a new therapeutic method for management of hepatic tumors. Here we report a new technique for hepatectomy using ultrasound-guided RF, which renders liver resection a less complex surgical procedure. Under intraoperative ultrasound (IOUS) guidance, a Cool-Tip RF probe is inserted into the liver parenchyma surrounding the tumor. A zone of coagulative desiccation is created around the tumor ensuring a 1-cm resection margin. Then, using a scalpel, the liver parenchyma is divided, and the tumor is removed with minimal blood loss. RF works by the conversion of RF waves into heat. Coagulative desiccation occurs and results in sealing of blood and biliary vessels. This is a new technique for liver resection that enables the surgeon to operate in a virtually bloodless field without the use of ischemia, sutures, or ties. It also spares the need for intraoperative blood transfusion and postoperative intensive care unit facilities, and it reduces the length of in patient stay.
