Patients with airway foreign bodies have varied presentations. The presence of any radiologic finding suggests that endoscopy should be performed, as a foreign body is probable. The absence of any history or physical examination finding was associated with a low likelihood of a foreign body.

Children with a button battery impaction present with nonspecific symptoms that may account for a delay in medical care. We conducted a retrospective study of the clinical presentation, management, and complications associated with button battery ingestion in thepediatric aerodigestive tract and to evaluate the associated longterm morbidity. We reviewed the medical records of 23 patients who were treated for button battery impaction at our tertiary care children's hospitalfrom Jan. 1,2000,. through July 31,2013. This population was made up of 14boys and 9 girls, aged 7 days to 12 years (mean: 4 yr). Patients were divided into three groups based on the site of impaction; there were 9 impactions in the esophagus and 7 each in thenasal cavity andstomach. We compiled information on thetypeandsizeofeach battery, theduration of the impaction, presenting symptoms, treatment, and outcomes. The mean duration of battery impaction was 40.6, 30.7, and 21.0 hours in the esophagus, nasal cavity, andstomach, respectively. We wereable toidentify the specific type of battery in 13 cases; 11 of these cases (85%) involved a 3-V 20-mm lithium ionbattery, including all cases of esophageal impaction in which the type of battery was identified. The most common presenting signs and symptoms were vomiting (n =7 (30%j), difficultyfeeding (n = 5 [22%]), cough (n = 5), and bloody
