Esophageal Atresia Information

Esophageal Atresia is a disease which is very rare. Esophageal atresia (EA) with distal tracheo-esophageal fistula (TEF) is the most common congenital anomaly of the esophagus, followed by Esophageal atresia without TEF also known as pure esophageal atresia and pure TEF. Incidence is one in every 2500 live births. The trachea and esophagus initially begin as a ventral diverticulum of the foregut during the third intrauterine week of life. A proliferation of endodermal cells appears on the lateral aspect of this growing diverticulum. These cell masses will divide the foregut into trachea and esophageal tubes. Whether interruption of this normal event leads to tracheo-esophageal anomalies, or during tracheal growth atresia of the esophagus results because of fistulous fixation of the esophagus to the trachea remians to be proven. Polyhydramnios is most commonly seen in pure Esophageal atresia.
