Aerodigestive tract foreign bodies in the older child and adolescent.

This study was undertaken in order to establish the incidence of aerodigestive tract foreign body accidents among older children and adolescents, and to investigate the circumstances surrounding these events. A review of patients treated over a 5-year period identified 367 children from whom aerodigestive tract foreign bodies were removed. Seventeen percent of these patients were 5 years of age or older. Among these children, 88% aspirated nonfood items, half of which were school supplies; 78% of the group 5 years old and under aspirated food items. Among older children with esophageal foreign bodies, 31% had food impactions, compared with 7% in the younger group; 70% of these children had a history of some anatomic abnormality of the esophagus. These data suggest that older children and adolescents represent a distinct group of patients at risk for foreign body accidents. Pediatricians and parents of children in this age group should discourage the practice of using the oral cavity as a repository for school supplies, and should stress the need for adequate preparation and mastication of food, particularly among children with esophageal abnormalities.
