[Esophageal Foreign Body: Treatment and Complications]

The most common cause of esophageal foreign bodies in adults is meat in Western countries and fish bones in Asian countries, including Korea. Although most ingested foreign bodies pass spontaneously through the esophagus without any clinical sequelae, some sharp foreign bodies, such as fish bones embedded in the esophagus, require treatment. Endoscopic management is the first choice in the treatment of esophageal foreign bodies because it is quite safe and effective. Major complications occur as a result of esophageal perforation; in particular, sharp foreign bodies, such as fish bones, are more likely to cause perforation. Complications include mediastinitis, paraesophageal abscess, pneumomediastinum, subcutaneous emphysema, pneumothorax, tracheoesophagal fistula, aortoesophageal fistula, aspiration, and asphyxia. Unnecessary delays should be avoided in endoscopic intervention for esophageal foreign bodies to prevent complications.
