Reduced Neuronal Innervation in the Distal End of the Proximal Esophageal Atretic Segment in Cases of Esophageal Atresia with Distal Tracheoesophageal Fistula

摘要

Esophageal dysmotility is a common occurence after surgical repair of proximal esophageal atresia (EA) and distal tracheoesophageal fistula (TEF). The etiology of this motility disorder, however, remains controversial. Esophageal dysmotility also is present in isolated TEF or EA before surgery, suggesting a congenital cause. However, there is no information available in the literature with regard to the intramural nervous system of the human esophagus in EA-TEF.
