The most common initial symptom of esophageal atresia with tracheoesophageal fistula is:

• A. Respiratory distress at delivery (retractions, tachypnea)
• B. Pneumonia
• C. Hypoxia
• D. Regurgitation during feeding

Answer: (D)

In esophageal atresia with a tracheoesophageal fistula, the upper esophagus ends in a blind pouch while the lower segment connects to the trachea. This arrangement blocks the passage of swallowed material into the stomach and instead redirects it toward the airway through the fistula. Because saliva and feeds cannot reach the stomach, regurgitation during feeding is a common first sign—the swallowed milk or saliva tends to back up and may trigger coughing or choking as it briefly enters the airway. The inability to swallow secretions also leads to excessive drooling, which often accompanies the initial presentation. Respiratory distress, hypoxia, or pneumonia can develop later from aspiration, but the hallmark early clue is regurgitation or choking with feeds.
