Case of the missing penny: thoracoscopic removal of a mediastinal coin.

Complications of coin ingestion in children, although rare, include esophageal perforation, tracheoesophageal fistula, esophago-aortic fistula, and death. The authors describe thoracoscopic removal of a mediastinal coin that migrated extraluminally from the esophagus in a 23-month-old girl. Right-sided thoracoscopic exploration using a 3-trocar technique in a modified prone position was used. Coin location was assisted by manipulation of a transorally placed Foley catheter and intraoperative fluoroscopy. The coin was retrieved successfully with no intraoperative or postoperative complications and minimal postoperative pain. This is the first report of successful thoracoscopic removal of a mediastinal coin. Thoracoscopy may be a valuable approach for mediastinal foreign body removal in children.
