title: A retrospective analysis of airway endoscopy in patients less than 1-month old.
abstract: OBJECTIVE
  To review the authors' experience with neonates who underwent endoscopy over an 8-year period.
  
  
  METHODS
  Retrospective review in a tertiary care children's hospital.
  
  
  METHODS
  Sixty-two neonates who underwent endoscopy were reviewed.
  
  
  RESULTS
  Common indications for endoscopy were stridor (56%), apnea/cyanotic episodes (30%), and feeding difficulty (23%). Laryngeal abnormalities were the most frequent finding, including laryngomalacia (19%), glottic edema (19%), and vocal cord paralysis (13%). Pierre Robin sequence was the most common associated anomaly. Forty-eight neonates (77.4%) had more than one endoscopic finding. Gastroesophageal reflux diagnosed by barium swallow or esophageal pH monitoring was found in 34%. Gastroesophageal reflux was the only identified etiologic factor in four cases. Computed tomography and magnetic resonance imaging provided less information than endoscopy.
  
  
  CONCLUSIONS
  Endoscopy in symptomatic neonates can determine etiology of distress most of the time. Multiple diagnoses were found in 77.4% of the neonates, emphasizing the need for a thorough aerodigestive tract examination. Concomitant diagnoses including gastroesophageal reflux, congenital heart disease, and pulmonary disease were found in 87.1% of neonates. Neonates have a higher likelihood of having multiple lesions in the aerodigestive tract as compared with older infants or children.
