Esophageal atresia is commonly associated with which of the following?

• A. Tracheoesophageal fistula
• B. Bowel atresia
• C. Meconium ileus
• D. Duodenal atresia

Answer: (A)

Esophageal atresia arises from an early foregut development error that disrupts the normal separation of the esophagus and trachea. The most common form is esophageal atresia with a distal tracheoesophageal fistula, where the upper esophageal pouch ends blindly while the lower esophagus forms a connection to the trachea. This shared developmental pathway explains why a tracheoesophageal fistula is the classic associated finding. The other listed GI anomalies are separate conditions and not the typical partner with esophageal atresia.
