Bronchobiliary fistula is a rare condition that thoracic surgeons may be expected to encounter. It can be congenital or acquired (resulting from a biliary infection,
1 malignancy,
2 surgery,
2,3 or trauma
4). Surgery remains the mainstay of treatment of congenital bronchobiliary fistula. However, interventional radiology and gastroenterologic techniques of stenting provide a realistic alternative to surgical intervention in acquired fistula in patients, many of whom have significant concomitant medical conditions.

A 46-year-old woman with advanced colon carcinoma had a 10-day history of increasing jaundice. Ultrasonography revealed hilar lymphadenopathy and dilated intrahepatic ducts. An initial percutaneous ultrasound and fluoroscopically guided percutaneous transhepatic cholangiogram (PTC) revealed occlusion of the common hepatic duct but no bronchobiliary fistula. An external biliary stent was placed to decompress the biliary tree before elective biliary stenting.
Within the next 24 hours a productive cough developed with frank biliptysis. A bronchoscopic study demonstrated purulent bile-stained material throughout the bronchial tree, especially in the right lower lobe, but no obvious fistulous connection. Owing to the clinical diagnosis of bronchobiliary fistula, a biliary excretion scintigraphic (hepato-iminodiacetic acid, HIDA) scan was performed(Fig 1). This scan revealed contrast medium in the biliary tree, which had a direct communication with the bronchial tree. Neither right lower lobectomy nor hepatic surgery was considered appropriate because of the patients condition. An expandable metal stent was deployed to relieve the biliary obstruction with the aid of a guide wire placed via the external biliary stent, which had been placed previously. Stenting resulted in a rapid improvement in the patients clinical condition. Unfortunately, she died 9 months later of advanced colon carcinoma with no recurrence of the biliptysis.

Radiologic and gastrointestinal interventions via external and internal stenting, respectively, can be successful in reducing biliary obstruction. This conforms to the first point in the traditional 3-step surgical management of fistulas: remove distal obstruction, excision, or decrease flow. Only after nonoperative, interventional techniques have failed should operative approaches be considered, especially in patients with advanced concomitant diseases.
