Right thoracotomy, conventional approach to esophageal atresia repair, leads to up to 60% radiological chest wall sequelae anomalies. The impact of these anomalies on the patient's respiratory function remains unknown. Minimally invasive thoracic surgery considerably reduces this rate.~The primary objective of this study is to assess the occurrence of restrictive lung disease in patients with type III esophageal atresia depending on the type of surgical approach (Conventional or minimally invasive).~The primary endpoint will be the occurrence of restrictive lung disease, as assessed by pulmonary function tests (PFTs), carried out according to the current national guidelines (PNDS = protocole national de diagnostic et de soins).~The secondary endpoints will be to measure the severity of the restrictive disease, to look for other respiratory alterations, to correlate radiological chest wall sequelae anomalies with the impact on respiratory function and to look for a causal relationship between the surgical technique used and the respiratory impact.~The methodology used will be a retrospective non interventional study on the cohort of patients included in the national esophageal atresia registry (CRACMO, Lille University Hospital) between the 1st of january 2008 and the 31st of December 2013.~All the patients included in the national esophageal atresia registry (CRACMO) having had an operation for type III esophageal atresia (long gap esophageal atresia excluded), as defined by the Ladd Classification, will be included in this study.~The exclusion criterion will be patients lost to follow up or deceased, patients having had no pulmonary function tests (PFTs) or no thoracic X-Ray during the first 6 to 9 years of follow up and patients having had thoracic surgery before the esophageal atresia repair.~The number of patients expected in the national esophageal atresia registry over the 6 years excedes 500. The number of thoracoscopy repairs should be about 50.~This study should allow us to determine if minimally invasive surgery is beneficial on mid-term respiratory function in children, related to possible post-operative chest wall sequelae.~The results obtained from this study should lead to recommendations concerning the surgical approach to esophageal atresia repair to improve the prognosis of chest wall anomalies and respiratory function in these patients. It should also help to identify patient subgroups which would benefit from a reinforced respiratory follow up. This could then lead to a hospital clinical research program (PHRC)
