[edit] Discussion of Esophageal atresia

  • Esophageal atresia, with or without tracheoesophageal fistula, is the most common congenital malformation of the esophagus.
  • In 25% of cases, the anomaly is associated with other gastrointestinal malformations such as imperforate anus, hypertrophic pyloric stenosis, duodenal atresia, annular pancreas, and, less frequently, with cardiac, genitourinary, and vertebral changes.
  • In approximately 70% of cases, the "VACTERL" complex is associated with tracheoesophageal anomalies.
  • Different types of atresia are recognized depending on the presence or absence of tracheoesophageal fistula and its location. These were classified by R. E. Gross (1953) as follows:
    • Type A: Corresponds to pure esophageal atresia without fistula
    • Type B: Esophageal atresia with fistula between the proximal pouch and the trachea
    • Type C: Esophageal atresia and fistula from the trachea or the main bronchus to the distal esophageal segment. This is the most common.
    • Type D: Esophageal atresia with both proximal and distal fistulas
    • Type E: Tracheoesophageal fistula without atresia.
    • Esophageal atresia was not included in the classification by Gross.

  • Esophageal atresia is suspected on the basis of polyhydramnios, inability to swallow saliva or milk, aspiration during early feedings, or failure to successfully pass a catheter into the stomach.

[edit] Imaging Findings for Esophageal atresia

  • Radiologic diagnosis of esophageal atresia is made by detecting a blind pouch of the proximal esophagus that is distended with air.
  • Radiographic evaluation should always include the abdomen to look for the presence of air in the gastrointestinal tract (distal fistula).
