  • Associated with esophageal atresia and other VACTERL anomalies including
    • vertebral
    • anal
    • cardiac
    • tracheal
    • esophageal
    • renal
    • limb defects
  • Epidemiology
    • occurs in roughly 1:4000 births
Presentation
  •  Symptoms
    • increased oral secretions
    • feeding difficulty
    • gagging/choking
    • hyperventilation or other respiratory dysfunction
  • Physical exam
    • respiratory distress
    • polyhydramnios in utero
    • rales on pulmonary ausculation
    • cyanosis
    • abdominal distention
      • caused by swallowing air during feeding
  •  
Evaluation
  • CXR
    • may show NG tube coiled in esophagus 
  • KUB
    • may identify air in the GI tract
  • Bronchoscopy
    • confirms anatomic abnormality (i.e. narrowing of esophagus and/or fistula)
  • Prenatal Ultrasound
    • may show polyhydramnios
Differential
  •  Esophageal atresia
Treatment
  •  Surgical intervention
    • surgical repair
      • considered a surgical emergency when identified
      • prevents further lung damage
