Esophageal Atresia with Distal Tracheoesophageal Fistula

Esophageal Atresia with Distal Tracheoesophageal Fistula is a birth defect affecting the esophagus, the tube that carries food from the mouth to the stomach. In this condition, the esophagus does not form properly and ends in a blind pouch instead of connecting to the stomach. Additionally, there is an abnormal connection called a fistula between the lower part of the esophagus and the trachea (windpipe). This causes food and saliva to enter the lungs, leading to coughing, choking, and breathing problems. Babies with this condition often have difficulty feeding and may develop serious lung infections. It primarily affects the digestive and respiratory systems and requires prompt medical attention after birth.

Esophageal Atresia with Distal Tracheoesophageal Fistula (EA with TEF) is a congenital malformation characterized by a discontinuity of the esophagus with the proximal segment ending blindly and the distal segment connected abnormally to the trachea via a fistula. This defect results from incomplete separation of the foregut into the trachea and esophagus during embryogenesis. The presence of the distal fistula allows gastric contents to reflux into the trachea, causing aspiration pneumonia and respiratory distress. Clinically, it presents with excessive salivation, choking, coughing, and inability to feed. It is the most common type of esophageal atresia, accounting for approximately 85% of cases. The condition is significant due to the risk of airway compromise, malnutrition, and recurrent pulmonary infections if untreated.
