Esophageal atresia with pulmonary agenesis
Insights
Infants with esophageal atresia and lung agenesis or severe pulmonary hypoplasia have a fatal outcome. Congenital heart disease, prematurity, and other anomalies contribute to mortality in these rare neonatal cases.
Area of Science:
- Neonatal medicine
- Pediatric surgery
- Developmental biology
Background:
- Esophageal atresia (EA) is a congenital anomaly of the foregut.
- Agenesis of the lung is a rare congenital anomaly.
- Pulmonary hypoplasia is characterized by incomplete lung development.
Observation:
- Two neonates presented with esophageal atresia and agenesis of the right lung.
- A literature review identified 11 additional cases of esophageal atresia with severe pulmonary hypoplasia.
Findings:
- All infants (13 total cases) with esophageal atresia and severe pulmonary hypoplasia or lung agenesis died.
- Congenital heart disease accounted for 50% of the mortality.
- The remaining deaths were attributed to prematurity and other severe congenital anomalies, alongside respiratory complications.
Implications:
- This condition represents a severe spectrum of congenital anomalies with universally fatal outcomes.
- Early identification and management strategies for associated anomalies are critical.
- Further research into the genetic and environmental factors underlying these complex malformations is warranted.
Abstract:
Two neonates with esophageal atresia and agenesis of the right lung are described. Review of the literature on the subject revealed an additional 11 cases of esophageal atresia associated with severe pulmonary hypoplasia. All of the affected infants died. Half of the deaths were caused by congenital heart disease, and the others were due to prematurity combined with various other severe anomalies and respiratory complications.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
