Tracheoesophageal Fistula (TEF) is a congenital condition where an abnormal connection forms between the trachea (windpipe) and the esophagus (food pipe). This can lead to serious complications, as food and liquids can enter the lungs, causing choking or aspiration pneumonia. TEF is often diagnosed in newborns and may be associated with other birth defects. Treatment for TEF typically involves surgery to close the abnormal connection and repair the esophagus. Early diagnosis and intervention are crucial for improving outcomes. After surgery, many children can lead healthy lives, although they may require ongoing monitoring and care.
