Ingested ring-pull causing bronchoesophageal fistula and transection of the left main bronchus: successful salvage of the left lung and esophagus five years after injury.

A 6-year-old girl with a history of ingestion of a ring-pull of a can and a transient episode of stridor had been asymptomatic 3 years before admission when left lung atelectasis with severe respiratory distress developed. Fluoroscopy and 3-dimensional computed tomography scan showed bronchoesophageal fistula and the ring-pull around the left main bronchus. At operation, the ring-pull, which transected the left main bronchus, was extracted. The left main bronchus was reconstructed by end-to-end anastomosis in spite of insufficient inflation of the collapsed left lung. The esophageal defect was repaired. The patient's respiratory distress gradually disappeared, and the x-ray films 3 months after operation showed complete expansion of the left lung. This case shows the risk of the long-term retained esophageal foreign body and the possibility of pulmonary salvage after long-term total atelectasis of the lung.
