Question: A 22-month-old child was taken to the emergency room by his parents owing to continuous drooling, irritability, and refusal of food intake. He presented with a body temperature of 37.4°C, heart rate of 144 bpm, and blood pressure of 100/60 mm Hg. Laboratory tests showed a white blood cell count of 28.1 × 103 cells/μL, a hemoglobin of 13.5 g/dL, and a C-reactive protein of 19.1 mg/dL. There were no electrolyte imbalances or coagulopathy. A plain chest radiograph revealed a disc-shaped metallic object in the upper esophagus, but no evidence of pneumomediastinum (FigureA).
