We have previously described thoracoscopic thermal ablation therapy for hepatocellular carcinoma (HCC) located just beneath the diaphragm, in nine patients with advanced liver cirrhosis [1]. We report here the application of that technique for HCC which had invaded above the diaphragm and was accompanied by intractable hemothorax.
In 1996, a 55-year-old man was treated with interferon for chronic hepatitis caused by hepatitis C virus (HCV), and his liver function test became normal with negative results for serum HCV-RNA. In 1999, he was diagnosed with HCC on the basis of ultrasonographic examination and an increased level of serum α-fetoprotein (20 000 ng/ml). The size of the tumor was 6.8 cm in S8 and 3.3 cm in S2. He was treated with percutaneous radiofrequency ablation therapy [2] after transcatheter arterial emoblization (TAE). In February 2000, he suffered from dyspnea, and the chest radiograph showed massive right pleural effusion. Thoracocentesis also showed the bloody effusion. TAE was carried out, but was not effective. Blood transfusion and thoracocentesis were repeated for 2 months. In May 2000, thoracoscopy was carried out under general anesthesia and 2 l of bloody pleural effusion were collected. After aspiration, the HCC could be seen invading above the diaphragm (Figures [1] a, b). To stop the bleeding, radiofrequency ablation using a LeVeen needle was carried out (Figure [1 c]), as described previously [1]. Ablation took about 85 minutes in total. After ablation, the tumor turned black in colour (Figure [1 d]) and the bleeding was completely stopped. The tumor was too large, and invaded too deeply into the liver, for complete ablation. However, the hemothorax disappeared after the procedure. The patient was discharged 3 days after treatment. There was no complication and no sign of hemothorax after ablation therapy up to the patient's death, from infiltration of the HCC into the inferior vena cava, in September 2000.
Thoracoscopic thermal ablation therapy can be an optional therapy for HCC located above the diaphragm and associated with intractable hemothorax.
