Esophageal atresia affects 1 in 2,500 live births.
EpidemiologicalDaniel von Allmen
Esophageal atresia is a congenital anomaly in which the esophagus doesn't form completely, with multiple different variants, one of the most common including a tracheoesophageal fistula.
ClinicalAaron Garrison
Infants with isolated esophageal atresia are sometimes diagnosed prenatally because the mother can have polyhydramnios during gestation.
ClinicalAaron Garrison
Patients with tracheoesophageal fistula usually don't present until after birth when they have problems feeding, and a Repogle tube meets resistance at typically 10 to 12 centimeters.
ClinicalDaniel von Allmen
X-ray after NG tube placement demonstrates the tube coiled in the upper part of the chest in the proximal pouch of the atretic esophagus.
ClinicalAaron Garrison
Injecting air into the NG tube prior to X-ray will distend the proximal pouch; if it doesn't distend, either the diagnosis is wrong or there could be a proximal fistula.
ClinicalDaniel von Allmen
40 to 60% of babies with esophageal atresia can have other associated anomalies.
EpidemiologicalAaron Garrison
About 20% of babies with esophageal atresia can have other findings within the VACTERL association.
EpidemiologicalAaron Garrison
About 5% of babies with esophageal atresia can have genetic syndromes.
EpidemiologicalAaron Garrison
The VACTERL association includes vertebral anomalies, anorectal malformations, cardiac anomalies, tracheoesophageal fistula, renal defects, and limb anomalies.
ClinicalAaron Garrison
The most pressing study needed is an echocardiogram to look at cardiac function and ensure there are no other congenital heart anomalies, and to identify which side the aortic arch is on.
ClinicalDaniel von Allmen
VACTERL workup includes renal ultrasound and spine ultrasound, which doesn't need to be done immediately after birth.
ClinicalDaniel von Allmen
To be considered truly VACTERL, you need at least three of the associations.
ClinicalDaniel von Allmen
There are five different types of EA or TEF, with two types accounting for over 90% of presentations.
EpidemiologicalAaron Garrison
Type C is the most common type of esophageal atresia, which is esophageal atresia with a distal fistula where the esophagus distally fistulizes to the trachea, usually a couple centimeters above the carina.
ClinicalAaron Garrison
Type A (isolated esophageal atresia with no fistula to the trachea) is the next most common type at about 8% of incidence.
EpidemiologicalAaron Garrison
H-type (more accurately N-type) esophageal atresia has an intact esophagus but a fistula between the trachea and esophagus, typically high, and is uncommon.
ClinicalDaniel von Allmen
Other very uncommon types include proximal fistula or proximal and distal fistula to the trachea.
ClinicalDaniel von Allmen
Initial management involves ensuring the Repogle is in a good position to decompress saliva or secretions and minimize aspiration while completing the workup.
ClinicalAaron Garrison
For the most common type of esophageal atresia, management is to stabilize the patient and get them to the OR, with almost all babies needing surgery within the first day or two depending on stability and medical comorbidities.
ClinicalDaniel von Allmen
Every child with esophageal atresia should undergo bronchoscopy at their initial trip to the operating room.
OpinionAaron Garrison
Bronchoscopy is performed to evaluate for the location of a proximal fistula, evaluate the degree of tracheomalacia, and help position the endotracheal tube to minimize the risk of insufflating the GI tract.
ClinicalDaniel von Allmen
Type C esophageal atresia can be repaired thoracoscopically or open, with the operation involving ligation of the tracheoesophageal fistula and bringing the two ends of the esophagus together to create a new anastomosis.
ClinicalAaron Garrison
Chest tubes are almost always used after repair.
ClinicalAaron Garrison
Extubation is attempted in one to two days, minimizing the risk of using high flow or CPAP following extubation, so the child should be in good respiratory shape when the tube is pulled.
ClinicalDaniel von Allmen
Most surgeons get an esophagram five to seven days after the operation to check for leak prior to removing the chest tube or starting feeds.
ClinicalAaron Garrison
One of the most common short-term complications is a leak following repair, usually diagnosed with spit coming out of the chest tube, and managed with observation.
ClinicalDaniel von Allmen
The second most common complication is stricture.
ClinicalDaniel von Allmen
Recurrent fistula is a less common early complication.
ClinicalDaniel von Allmen
Reflux is a longer-term complication.
ClinicalDaniel von Allmen
Other long-term complications include respiratory issues like reactive airway disease and esophageal dysmotility.
ClinicalAaron Garrison
Survival of esophageal atresia patients has improved over the years and is now about 85 to 95% overall survival.
EpidemiologicalAaron Garrison
Lower survival is typically seen in more complex patients with other cardiac, renal, and/or pulmonary anomalies.
ClinicalAaron Garrison
Having a multidisciplinary approach that's coordinated is important to achieving the best outcomes for these patients in the long term.
