BACKGROUND/AIMS: The majority of @entity157 @entity1 with @entity82 are not candidates for surgical resection, and local thermal therapy producing destruction of @entity5 cells was one of the ideal options for treatment. Heat from radiofrequency ablation is generated through @entity2146 caused by an alternating electrical current. The heat of radiofrequency energy results in local cell coagulation and causes cellular ablation necrosis of @entity5 tissue. METHODOLOGY: Eighteen cases of @entity157 were treated with radiofrequency ablation in our institute. We used a RFA 2000 generator (Boston Scientific Co, USA) with LeVeen needle with the maximum diameter of 3.5 cm when the array electrodes were fanned out. The indications for this method included; i) normal prothrombin profile, ii) no ascites, iii) @entity5 can be detected and approached by ultrasound, iv) @entity5 cannot be resected or @entity1 is not willing to take the operation. RESULTS: No specific complication was noted during or after the procedure. Only two cases needed more analgesics after the procedure. One case was found with burning of the stomach serosa proved by laparoscopic examination, in which radiofrequency ablation was performed to the @entity5 located in the left lobe of the segment 3. Impedance could not raise up completely in two cases with larger size @entity5 more than 5 cm. The decreased levels of @entity160 were significant (P = 0.005) after radiofrequency ablation treatment. @entity41 was found in four cases (20%) in the follow-up abdominal computed tomography scan. CONCLUSIONS: Radiofrequency ablation resulted in a higher rate of complete necrosis of @entity5 tissue and the complication rate was low as well. Therefore, we believed that radiofrequency ablation is an ideal treatment modality for most @entity96 , which cannot tolerate the conventional surgical procedures.
