Esophageal atresia is a disorder of the esophageal continuity with or without a connection\nwith the trachea or the under-development esophagus. Most babies who suffer\nfrom esophageal atresia also have tracheoesophageal fistula (an abnormal connection\nbetween the esophagus and the trachea/windpipe). The possibility of these two\nconditions is accompanied by other anomalies such as congenital heart disease and\nanorectal malformations. Esophageal atresia can also be interpreted as malformations\ncaused by the failure of the esophagus to develop a continual passage that may\nor may not establish a connection to the trachea (tracheoesophageal fistula) or it can\nbe said that the esophageal atresia is the failure of the esophagus to form a channel\nfrom the pharynx to the stomach during embryonic development. Another understanding\nof esophageal atresia is an interruption in the growth of a segment of the\nesophagus and remains as thin sections without continual channels. Tracheal esophageal\nfistula is an abnormal connection between the trachea and esophagus. Miscellaneous\ntypes of esophageal atresia include: Type A. The incidence of Type A\nesophageal atresia was about 5% - 8%. Type A esophageal atresia occurs at each end\nof the esophageal sac, and is apart without fistula to the trachea. Type B incident is\nrare. Type B esophageal atresia occurs at each end of the esophagus, and there is fistula\nfrom the trachea to the upper segment of esophagus. Incidence of Type C esophageal\natresia occurs about 80% - 95%. Type C esophageal atresia occurs at the\nproximal esophageal segment and ends at a dead-end sac, and distal segments are connected\nto the trachea or primary bronchus. Type D esophageal atresia is rare. In this\ntype, upper and lower segment of the esophagus is connected to the trachea. Type E\nesophageal atresia is rare when compared with Types A and C esophageal atresia. In\nthis type the esophagus and trachea are normal but they are connected with fistula.
