Which finding in a newborn is suggestive of tracheoesophageal fistula?
Explanation & Rationale
Choice A reason: Tracheoesophageal fistula (TEF) involves an abnormal tracheoesophageal connection, causing aspiration during feeding. In newborns, choking on the first feeding occurs as milk enters the airway via the fistula, leading to respiratory distress. This is a hallmark sign, requiring urgent evaluation to confirm TEF and prevent complications like pneumonia. Choice B reason: A palpable mass in the sternal area may indicate a congenital anomaly like a sternal cleft or tumor, but it is not associated with tracheoesophageal fistula. TEF affects airway and esophageal function, causing choking during feeding, not palpable masses, making this finding irrelevant to the condition’s pathophysiology. Choice C reason: Visible peristalsis across the abdomen suggests gastrointestinal motility issues, like hypertrophic pyloric stenosis, but is not specific to tracheoesophageal fistula. TEF causes respiratory symptoms like choking due to airway aspiration, not abdominal motility changes, making this finding incorrect for diagnosing this congenital airway-esophageal defect. Choice D reason: Failure to pass meconium in 24 hours suggests Hirschsprung’s disease or intestinal atresia, affecting bowel motility. Tracheoesophageal fistula primarily impacts feeding and respiration due to airway-esophageal connection, not meconium passage, making this finding unrelated to the condition’s presentation in a newborn during feeding.
