Esophageal atresia. Lessons I have learned in a 40-year experience.

A brief resume of the highlights in the history of oesophageal atresia is presented. This is followed by research into the etiology, ontogeny and embryology, and microbiological studies. A revised classification of risk factors with consequent survival statistics is presented. Lessons learned in the management of the condition over a 40-year period are reported with particular emphasis on the management of the preterm infant with associated severe respiratory distress, right-side aortic arch, upper pouch fistula, 'long-gap' atresia, and the use of gastrostomy and intercostals drains. The incidence and treatment of early and late complications is discussed.
