Biliary pleural fistula detected by hepatobiliary scintigraphy.

A biliary pleural fistula is a rare complication secondary to trauma, infection, malignancy, biliary disease, malignancies, or percutaneous procedures. Its presence may be suggested by the development of a right pleural effusion in a patient with such history and can be confirmed with a hepatobiliary scan or endoscopic retrograde cholangiopancreatography. Patients are treated with antibiotics and the fistula usually spontaneously closes. If after 2 weeks the fistula persists, percutaneous drainage, sphincterotomy, or biliary stent placement can be performed to promote healing of the fistula. In complicated cases, open thoracic surgery or video-assisted thoracic surgery may be required.
