What causes tracheoesophageal fistula and esophageal atresia?
The trachea and the esophagus start forming as 1 tube. At 4 to 8 weeks of pregnancy, a wall forms between the esophagus and trachea. This separates them into 2 tubes. TE fistula and esophageal atresia happen when this wall doesn’t form as it should.
Why does esophageal atresia happen?
It occurs during a baby’s development before birth. Mutations (changes) to genes may cause the esophagus to develop abnormally. The esophagus and trachea form at about the same time in the womb. In babies with esophageal atresia, the esophagus doesn’t form into one long tube between the baby’s mouth and stomach.
How common is tracheoesophageal fistula?
Normally, the esophagus and the trachea are two separate tubes that are not connected. Tracheoesophageal fistula is also known as TE fistula or simply TEF. TE fistula is a birth defect, which occurs in 1 in 5,000 births, and occurs as a fetus is forming in its mother’s uterus.
What is associated with tracheoesophageal fistula?
A tracheoesophageal fistula (TEF) is an abnormal connection between these two tubes. As a result, swallowed liquids or food can be aspirated (inhaled) into your child’s lungs. Feeding into the stomach directly can also lead to reflux and aspiration of stomach acid and food.
Is esophageal atresia hereditary?
When EA/TEF occurs as a feature of a genetic syndrome or chromosomal abnormality, it may cluster in families according to the inheritance pattern for that condition. Often EA/TEF is not inherited, and there is only one affected individual in a family.
How common is esophageal atresia?
Researchers estimate that about 1 in every 4,100 babies is born with esophageal atresia in the United States. This birth defect can occur alone, but often occurs with other birth defects.
How do you get esophageal atresia?
The exact cause of EA is still unknown, but it appears to have some genetic components. Up to half of all babies born with EA have one or more other birth defects, such as: trisomy 13, 18 or 21. other digestive tract problems, such intestinal atresia or imperforate anus.
Is esophageal atresia curable?
Without a working esophagus, it’s impossible to receive enough nutrition by mouth. Babies with EA are also more prone to infections like pneumonia and conditions such as acid reflux. Luckily, EA is usually treatable.
Is esophageal atresia rare?
What is esophageal atresia?
Esophageal atresia is a birth defect in which part of a baby’s esophagus (the tube that connects the mouth to the stomach) does not develop properly. Esophageal atresia is a birth defect of the swallowing tube (esophagus) that connects the mouth to the stomach.
How does esophageal atresia affect a baby’s breathing?
A baby with esophageal atresia has a connection between the esophagus and the trachea (windpipe) going in to the lungs. Normally, the esophagus and the trachea are two separate tubes that are not connected to one another.
What is the relationship between esophageal atresia and the windpipe?
Newborns with esophageal atresia often also have a tracheoesophageal fistula which is a direct connection between the esophagus and the trachea (windpipe).
How is esophageal atresia treated in babies with TE fistula?
However, babies with pure esophageal atresia usually have a longer distance between the two ends of the esophagus. There are several approaches to surgical correction of esophageal atresia without TE fistula, but in most cases, the best treatment is a gastrostomy tube.
