What is EA and TEF?

Esophageal atresia (EA) and tracheoesophageal fistula (TEF) are rare conditions that develop before birth. They often occur together and affect the development of the esophagus, trachea or both. These conditions can be life-threatening and must be treated shortly after birth.

How common is TEF EA?

Esophageal atresia/tracheoesophageal fistula (EA/TEF) is a rare birth defect occurring in 1 in 2,500-4,000 babies where the esophagus fails to properly connect the mouth to the stomach. Babies with this condition must undergo surgical repair, usually shortly after birth.

When is EA TEF diagnosis?

The diagnosis of EA/TEF is confirmed by attempting to pass a nasogastric tube (a tube that runs from the nose to the stomach via the esophagus) down the throat of infants who have require excessive suction of mucus, or are born to mothers with polyhydramnios, or, if earlier signs are missed have difficulty feeding.

What are the 5 types of tracheoesophageal fistula?

Type A = pure esophageal atresia; type B = esophageal atresia with proximal tracheoesophageal fistula; type C = esophageal atresia with distal tracheoesophageal fistula; type D = esophageal atresia with proximal and distal tracheoesophageal fistula; type E = H-type tracheoesophageal fistula without esophageal atresia.

What is EA disease?

An esophageal atresia (EA) and a tracheoesophageal fistula (TEF) are 2 disorders of the digestive system. The condition affects babies. It starts while the mother is pregnant. This makes it a congenital defect. The 2 disorders often happen together.

Is EA TEF genetic?

Causes. Isolated EA/TEF is considered to be a multifactorial condition, which means that multiple gene variations and environmental factors likely contribute to its occurrence. In most cases of isolated EA/TEF, no specific genetic changes or environmental factors have been conclusively determined to be the cause.

What are the types of EA?

EA with Distal TEF EA, with a distal TEF, or a TEF connecting between the lower pouch of the esophagus and the trachea. This is by far the commonest type of EA, with about 89% of EA patients having this type.
