Pediatric esophageal atresia is absence or abnormal narrowing of an opening in the body. It is a congenital defect of the esophagus that occurs in early stages of pregnancy while the baby is developing. The condition occurs due to malformation consisting of discontinuity between the upper and lower esophageal pouches. The defect is frequently associated with tracheoesophageal fistula. In tracheoesophageal fistula, babies have their esophagus abnormally attached with windpipe (trachea).
