After diagnostic measures such as bronchoscopy, computed tomography (CT) scan, endoscopic retrograde cholangiopancreatography (ERCP), and confirmation of the diagnosis of BBF, the patient underwent Intravenous (IV) antibiotic therapy, placement of pleural drain, sphincterotomy and CBD stents insertion but unfortunately, these measures were not effective and the patient was a candidate for thoracotomy and resection of fistula and the involved lung.
