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.
