Etiology of esophageal atresia and tracheoesophageal fistula: "mind the gap".

ABSTRACT: Esophageal atresia and tracheoesophageal fistula (EA/TEF) are major congenital malformations affecting 1:3500 live births. Current research efforts are focused on understanding the etiology of these defects. We describe well-known animal models, human syndromes, and associations involving EA/TEF, indicating its etiologically heterogeneous nature. Recent advances in genotyping technology and in knowledge of human genetic variation will improve clinical counseling on etiologic factors. This review provides a clinical summary of environmental and genetic factors involved in EA/TEF.

Project description:BackgroundA communicating bronchopulmonary foregut malformation (CBPFM) group IB is very rare congenital malformation. Group IB is associated with tracheoesophageal fistula and esophageal atresia (TEF-EA) and a portion of one lung arisen from the esophagus (Gerle et al. in N Engl J Med. 278:1413-1419, 1968). The coexistence of TEF-EA and dextrocardia is also a rare and challenging setting for repair of TEF-EA. Therefore, the thoracoscopic surgery for TEF-EA require the technical devise because of the small operative space. We herein report a rare case of CBPFM group IB with intralobar sequestration of lung and a successful performing of thoracoscopic surgery for EA with dextrocardia in VACTERL association.Case presentationA 2.2-kg term male neonate was born with an anal atresia, coarctation of the aorta, TEF-EA, renal anomalies, radial hemimelia, limb abnormalities (VACTERL association) and hypoplasia of the right lung with dextrocardia. The patient developed respiratory distress after admission. A two-stage operation for the TEF-EA was planned because of multiple anomalies and cardiac condition. In the neonatal period, esophageal banding at the gastroesophageal junction and gastrostomy were performed to establish enteral nutrition. After gaining body weight and achieving a stable cardiac condition, thoracoscopic surgery for TEF-EA was performed. The thoracoscopic findings revealed a small working space due to dextrocardia. To obtain a sufficient working space and to perform secure esophageal anastomosis, an additional 3-mm assistant port was inserted. To close the upper and lower esophagus, anchoring sutures of the esophagus were placed and were pulled to suspend the anastomotic site. Esophageal anastomosis was successfully performed. An esophagogram after TEF-EA surgery showed the connection between the lower esophagus and right lower lung. The definitive diagnosis was CBPFM group IB with intralobar sequestration. The thoracoscopic surgery was performed again for establishing oral intake. After transection of the bronchoesophageal fistula, the patient could perform oral feeding without pneumonia or respiratory distress.ConclusionsCBPFM type IB with intralobar sequestration is a rare condition. CBPFM type IB should be considered for a patients with respiratory symptom after radical operation for TEF-EA. In the present case, suspending the anastomotic site was effective and useful in thoracoscopic surgery for a TEF-EA patient with dextrocardia.
