Esophageal atresia (EA) is a congenital malformation. Nowadays, its initial prognosis is excellent thanks to improvements in neonatal and surgical management. However, the assessment of long-term respiratory outcome has become necessary in affected children and was thus performed in this study. The benefits of cardiopulmonary function testing were also examined.
The medical records of 77 children operated on for EA between 1990 and 2004 were reviewed. The results of respiratory function testing and cardiopulmonary response to effort were collected, together with neonatal and anthropometric data.
Acceptable measurements were obtained in 31 children with EA. These children were comparable to the ones lost during follow-up. The results of pulmonary function tests (PFTs) were abnormal in 21 cases (68%). A poor ventilatory response was detected in 14 children (45%) by cardiopulmonary function testing. Ten children who had abnormal results on PFTs were not under any anti-asthmatic treatment.
Impaired lung function was noted in children with repaired EA. Indeed, cardiopulmonary function tests results correlated with standard spirometric parameters and revealed minimal clinical symptoms. Moreover, many children with EA had a limited ventilatory reserve (VR). These results indicate that respiratory symptoms are often neglected in children with repaired EA and reinforce the need to provide adequate treatment.
