Patients will be asked to have nothing by mouth during at least 8 hours prior to ablation. Patients will only be taken for cryoablation if INR is <1.5, PTT is within normal limits and platelet count is greater than 50,000/microL. Preoperative imaging, namely contrast enhanced CT scan, will be used to assess the tumor proximity to local structures. Number of cryoprobes utilized will be determined by the size, geometry, and morphology of the primary tumor. CT guidance will be used to place the cryoprobes 1 to 1.5 cm apart.
