A Case of Bronchobiliary Fistula Successfully Treated for Bronchial Occlusion Using Endobronchial Watanabe Spigot and Embolization Coils

Abstract

We herein report a case of a bronchobiliary fistula that was successfully treated for bronchial occlusion using an Endobronchial Watanabe Spigot (EWS) and embolization coils. A 66-year-old man who underwent radiofrequency ablation for hepatocellular carcinoma and endoscopic retrograde cholangiopancreatography for acute cholangitis developed a bronchobiliary fistula. Surgical treatment was difficult due to the patient's medical history and the underlying disease progression. Although percutaneous bile drainage was performed, only a partial response was observed. Thus, bronchial occlusion was treated using EWS and embolization coils. This case suggests that bronchial occlusion using bronchoscopy is a safe and effective treatment option for bronchobiliary fistulas.
