TEF is often associated with which congenital anomaly?

• A. Esophageal atresia
• B. Kidney anomalies
• C. Diaphragmatic hernia
• D. No associated anomalies

Answer: (A)

Tracheoesophageal fistula is most tightly linked to esophageal atresia. In the classic EA/TEF combination, the esophagus fails to form a continuous passage and a fistulous connection allows the distal esophagus to communicate with the trachea. This pairing is the hallmark because TEF almost always occurs with EA, shaping the clinical presentation and surgical approach. While other anomalies, such as kidney (renal) abnormalities, can appear as part of broader associations like VACTERL, they are not as directly tied to TEF as esophageal atresia. Diaphragmatic hernia is a separate defect, and TEF with no associated anomalies is not the typical scenario.
