The diameter of the echogenic response observed with intraoperative sonography during radiofrequency ablation of the cirrhotic liver correlates closely with the mean diameter of the subsequent area of tissue necrosis. However, the solitary diameter of the echogenic response as measured in our study was often greater than the smallest diameter and less than the largest diameter of the area of tissue necrosis. Therefore, the echogenic response associated with radiofrequency ablation of the cirrhotic liver should be viewed only as a rough approximation of the area of induced tissue necrosis; the final assessment of the adequacy of ablation should be deferred to an alternative imaging technique.

Corticosteroids can be safely avoided after POD 1 with the current regimen. With early follow-up, there is no difference in hypertension or diabetes or bone density. Lipid panels tended to be lower in patients who were not on corticosteroids. Longer term follow-up will be needed to demonstrate the potential advantage of corticosteroid avoidance in regard to hypertension, diabetes, and possibly HCV recurrence.

Ablation area is increased significantly with hepatic blood flow occlusion in the human cirrhotic liver. This result may have application in the treatment of larger (>3 cm) hepatic malignancies.
