Esophageal Atresia: Causes, Symptoms, and Treatment

What kind of doctor treats Esophageal Atresia?
A pediatric surgeon, a surgeon who operates on babies and children, repairs esophageal atresia. A neonatologist, a doctor who cares for sick newborns, usually manages the baby's early care. A baby with this condition needs care in a hospital right after birth. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is esophageal atresia?
Esophageal atresia (EA) is a birth defect in which the esophagus does not develop properly. The esophagus is the tube that normally carries food from the mouth to the stomach.
In most cases, the upper esophagus ends and does not connect with the lower esophagus and stomach.
Most babies with EA also have a tracheoesophageal fistula (TEF). This is an abnormal connection between the esophagus and the windpipe, which is also called the trachea. Fluids from the esophagus can then get into the airways and make breathing hard.
Symptoms
EA is usually found shortly after birth. Symptoms can include:
- Bluish skin color, called cyanosis, often when the baby tries to feed.
- Coughing, gagging, and choking when the baby tries to feed.
- Drooling or vomiting.
- Poor feeding.
Saliva and fluids collect in the esophagus, which makes the baby cough, choke, and sometimes turn blue. Liquids a baby is fed are spit back up because EA blocks them from reaching the stomach.
Causes and who gets it
EA is a congenital condition, which means it occurs before birth. The esophagus and windpipe start as a single tube. Between four and eight weeks after conception, this tube normally divides into two passages. If it does not divide properly, EA and TEF are the result.
EA and TEF occur in 1 in 3,000 to 5,000 newborns.
In most cases of isolated EA and TEF, no specific genetic changes or environmental factors have been proven to be the cause. Isolated means the baby has no other birth defects. This is true for about 40 percent of affected babies.
At least half of babies with EA and TEF have other birth defects, most often heart defects.
EA and TEF can also be part of a genetic syndrome, such as CHARGE syndrome, trisomy 18, or VACTERL association.
Often EA and TEF are not inherited, and only one person in a family is affected.
How doctors diagnose it
Before birth, a mother's ultrasound may show more amniotic fluid than usual. This can be a sign of EA or another blockage of the baby's digestive tract. The baby's stomach may also be hard to see.
After birth, the baby's provider tries to pass a small feeding tube through the mouth or nose into the stomach. If the tube cannot reach the stomach, the baby likely has EA.
Once EA is confirmed, other tests may include an echocardiogram, which is an ultrasound of the heart, to look for heart defects. Doctors may also use imaging to look for defects in the spine, limbs, or kidney.
Treatment
EA is an emergency. Surgery is done as soon as possible after birth.
First, any connection between the esophagus and the airway must be blocked. This prevents damage to the lungs. Then the esophagus is connected to the stomach. This may take time to complete, depending on the gap between the esophagus and the stomach.
Before the surgery, and for some time afterward, the baby is not fed by mouth. The baby is fed through a gastrostomy tube (G-tube), which puts food directly into the stomach, or through nutrition given into the veins.
Care is taken to keep the baby from breathing saliva or other fluids into the lungs.
An early diagnosis gives a better chance of a good outcome.
Possible problems include feeding problems, reflux (food coming back up from the stomach) after surgery, and narrowing of the esophagus from scarring after surgery.
When to see a doctor
EA is usually found shortly after birth. Contact your baby's provider right away if your baby vomits repeatedly after feedings.
Call 911 or go to the emergency room if your baby is choking, has trouble breathing, has bluish or grey skin, or is unconscious.
Breathing in saliva or other fluids can cause aspiration pneumonia, which is a lung infection, and choking. It can possibly cause death.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. EA is treated by a hospital team soon after birth. Later, this kind of doctor can follow feeding and growth, and help you coordinate visits with specialists.
Common questions
Is esophageal atresia an emergency?
Yes, esophageal atresia is an emergency. Surgery is done as soon as possible after birth.
Is esophageal atresia the same as a tracheoesophageal fistula?
No, but they often happen together. In EA, the upper esophagus does not connect to the lower esophagus and stomach. A TEF is an abnormal connection between the esophagus and the windpipe. Most babies with EA also have a TEF.
How common is esophageal atresia?
It is rare. EA and TEF occur in 1 in 3,000 to 5,000 newborns.
Is esophageal atresia passed down in families?
Often it is not. EA and TEF are often not inherited, and only one person in a family is affected.
