Types
This condition takes several different forms, often involving one or more fistulas connecting the trachea to the esophagus (tracheoesophageal fistula). Approximately 85% of affected babies will have a 'lower fistula'.
| Type | Name(s) | Description |
|---|---|---|
| Type A | "Long Gap", “Pure” or “Isolated” Esophageal Atresia | Esophageal Atresia without fistula.
Type A Esophageal Atresia is characterized by the presence of a “gap” between the two esophageal blind pouches. |
| Type B | Esophageal Atresia with proximal TEF (tracheoesophageal fistula) |
Esophageal Atresia where the upper esophageal pouch connects abnormally to the trachea. This abnormal connection is called a fistula. The lower esophageal pouch ends blindly. |
| Type C | Esophageal Atresia with distal TEF (tracheoesophageal fistula) |
Esophageal Atresia where the lower esophageal pouch makes an abnormal connection with the trachea. This abnormal connection is called a fistula. The upper esophageal pouch ends blindly. |
| Type D | Esophageal Atresia with both proximal and distal TEFs (two tracheoesophageal fistulas) |
Esophageal Atresia where the upper and lower esophageal pouches make and abnormal connection with the trachea in two separate, isolated places. The upper esophageal atresia also still ends in a blind pouch. |
| Type E | TEF (tracheoesophageal fistula) ONLY with no Esophageal Atresia
and there is a blind pouch over there hageal Atresia |
This rare form finds the esophagus fully intact and capable of its normal functions, however, there is an abnormal connection between the esophagus and the trachea. This abnormal connection is called a fistula. |
| Type F | Esophageal Stenosis |
Also known as an Esophageal Stricture. This rare form also finds the esophagus fully intact and connected to the stomach, however, the esophagus gradually narrows, causing food and saliva to become “caught” in the esophagus. On occasion, Type F can go undiagnosed until adulthood. |

Famous quotes containing the word types:
“He’s one of those know-it-all types that, if you flatter the wig off him, he chatter like a goony bird at mating time.”
—Michael Blankfort. Lewis Milestone. Johnson (Reginald Gardner)
“If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.”
—Henry David Thoreau (1817–1862)
“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
