TEF
Pronunciation: T-E-F
Also written as: TEF — Tracheoesophageal Fistula
Tracheoesophageal fistula, an abnormal connection between the trachea and esophagus occurring in newborns.
Full Definition
Tracheoesophageal fistula (TEF) is a congenital anomaly characterized by an abnormal communication between the trachea and esophagus, most commonly occurring in association with esophageal atresia. The condition presents in the immediate neonatal period with feeding difficulties, respiratory distress, and aspiration. Radiologic evaluation typically includes chest X-rays showing a gasless abdomen (in pure esophageal atresia) or gas-filled bowel (when TEF is present), and contrast studies to delineate the anatomy. The most common type is esophageal atresia with distal TEF. Early recognition and surgical repair are essential to prevent life-threatening aspiration pneumonia.
Usage
Usage note: May be written as TEF or T-E fistula. Always specify location (proximal, distal) when known.
