INTRODUCTION: Ingestion of button batteries (PB) represents less than 2% of all foreign bodies, but its incidence is increasing. Esophageal impaction produces severe damages, which can be devastating. Our aim is to present 3 new cases and the therapeutic protocol followed in our center. MATERIAL AND METHODS: We report 3 children who presented esophageal foreign body impaction, displaying a PB with the "double halo sign" on the radiograph, being situated in the upper, medium and low esophageal in each case. The protocol followed included: radiography of the neck, chest and abdomen; high doses of corticosteroids, inhibitors of proton pump, antibiotics and urgent endoscopy removal. A nasogastric tube was placed in the same act. RESULTS: The PB had been impacted for 10.3 hours (5-14) but had inflammation and necrosis of the esophageal mucosa. We applied the specified protocol. Oral feeding was initiated 8 +/- 2 days after with a normal esophagogastric study, which was repeated a month later to exclude stenosis. CONCLUSION: Adherence to a diagnostic and therapeutic protocol prevents the complications of esophageal impaction of button batteries. We consider the double halo image pathognomonic of the PB.
