Thoracic complications of radiofrequency ablation of recurrent hepatoma

Abstract

Introduction: Radiofrequency ablation (RFA) for unresectable primary or secondary hepatic malignancies have gained widespread availability and acceptance over the past 5 years. Complication rates have been reported to range from 0% to 27%. Clinical Picture: We report a patient with symptomatic right pleural effusion due to a diaphragmatic fistula and another with biliptysis post-RFA, for recurrent hepatoma. Treatment: Percutaneous drainage of both the pleural effusion and biloma was performed. However, surgical repair of the diaphragmatic fistula was only required for the former for persistent drainage. Outcome: Both patients were successfully treated with minimal morbidity. Conclusion: High index of suspicion is required for the early diagnosis and treatment of diaphragmatic fistulas. Simple catheter drainage can potentially obviate the need for surgery.
