Gene-targeted testing atresias esofagicas the clinician to hypothesize which gene s are likely involved, whereas genomic testing does not. A multigene panel that includes some or all of the genes listed in the Table 1 is most likely to identify the genetic cause of the condition at the most reasonable cost while limiting identification of variants of atresias esofagicas significance and pathogenic variants in genes that do not explain the underlying phenotype.

More detailed information for clinicians ordering genetic tests can be found here. Comprehensive genomic testing which does not require the clinician to determine which gene [s] are likely involved may be considered.
Exome sequencing is most commonly used; genome sequencing is also possible. Exome array when clinically available may be considered atresias esofagicas exome sequencing is not diagnostic. For an introduction to comprehensive genomic testing click here.
This can usually be dilated using medical instruments. In later life, most children with this disorder will have some trouble with either swallowing or heartburn or both. Tracheomalacia —a softening of the trachea, usually above the carina carina of tracheabut sometimes extensive in the lower bronchial tree as well—is another possible serious complication.
Even after esophageal repair anastomosis the relative flaccidity of former proximal pouch blind pouch, above along atresias esofagicas esophageal dysmotility can cause fluid buildup during feeding.
Owing to proximity, pouch ballooning can cause tracheal occlusion. Severe hypoxia "dying spells" follows atresias esofagicas medical intervention can often be required.
A variety of treatments for tracheomalacia associated with esophageal atresia are available. If not severe, the condition can be managed expectantly since the trachea will usually stiffen as the infant matures into the first atresias esofagicas of life.
When only the trachea above the carina is compromised, one of the "simplest" interventions is aortopexy wherein the aortic loop is attached to the rear of the sternum, thereby mechanically relieving pressure from the softened trachea.
An even simpler intervention is stenting. However, epithelial cell proliferation and potential incorporation of the stent into the trachea can make subsequent removal dangerous. Magnetic compression method[ edit ] A method for repairing long-gap esophageal atresia using magnets has been developed, that does not require replacing the missing section with grafts of the intestine or other body parts.
Using electromagnetic force to attract the upper and lower ends of the esophagus together was first tried in the s by using steel pellets attracted to each other by applying external atresias esofagicas to the patient.
In the s a further refinement was developed by Mario Zaritzky 's group and others. The newer method uses permanent magnets and a balloon. The magnets are inserted into the upper pouch via the baby's mouth or nose, and the lower via the gastrotomy feeding tube hole which would have had to be made anyway to feed the baby, therefore not requiring any additional surgery.
The distance between the magnets is controlled by a balloon in the atresias esofagicas pouch, between the end of the pouch and the magnet. This also controls the force between the magnets so it is not atresias esofagicas enough to cause damage.
After the ends of the esophagus have stretched enough to touch, the upper magnet is replaced by one without a balloon and the stronger magnetic attraction causes the ends to fuse anastomosis.
Instead, it ends as a blind pouch.

Tracheoesophageal fistula TEF represents an abnormal opening between the trachea and esophagus. EA and TEF can occur separately or together.
The presence of EA is suspected in an infant with excessive salivation drooling and in a newborn atresias esofagicas drooling that is frequently accompanied by choking, coughing and sneezing.
When fed, these infants swallow normally but begin to cough and struggle atresias esofagicas the fluid returns through the nose and mouth. The infant may become cyanotic turn bluish due to lack of oxygen and may stop breathing as the overflow of fluid from the blind pouch is aspirated sucked into the trachea.
