Gastrobronchial fistula: an unusual complication of Nissen fundoplication.

Gastrobronchial fistula is a rare complication of antireflux surgery. Presentation can be subacute, with only productive cough. Endoscopy often fails to visualize these fistulae. Barium in the bronchial tree during postoperative upper gastrointestinal series is diagnostic, but can be confused with that appearing due to aspiration. Every case reported after antireflux surgery has followed intrathoracic Nissen fundoplication.
