An open ablation of one or more liver tumors involves a surgical procedure where tumors located in the liver are targeted for destruction. This procedure is typically indicated for patients with liver tumors that may not be amenable to other forms of treatment. The process begins with a midline incision in the abdomen, allowing the surgeon access to the liver. During the operation, any adhesions that may obstruct the view or access to the liver are carefully lysed, utilizing both blunt and sharp dissection techniques. The abdominal cavity is thoroughly inspected to identify any extrahepatic tumors or other abnormalities that may be present. Once the liver is mobilized, all eight hepatic segments are inspected to locate the tumors. In this procedure, radiofrequency ablation is employed, which involves the use of a radiofrequency electrode needle that is guided into the center of the tumor using ultrasound guidance. The radiofrequency energy is then applied to heat the tumor to a specific temperature, which is maintained for a predetermined duration to ensure effective destruction of the tumor cells. After the heating cycle, the tissue is allowed to cool while the surgical team monitors the site to confirm that the entire tumor, along with a margin of healthy tissue, has been adequately destroyed. If necessary, the electrode needle may be repositioned at different angles or locations within the tumor to ensure complete necrosis. This process is repeated for any additional tumors present until all targeted tumors have been successfully ablated. Following the completion of the ablation, the surgical team releases any gas from the abdominal cavity, removes the laparoscope and surgical instruments, and closes the portal incisions to conclude the procedure.
