Oesophageal atresia is a congenital abnormality occurring with an incidence of about 1 in 2500 live births.

The oesophagus develops as a derivative of the foregut, from the floor of where the larynx and trachea become separated by the laryngo-tracheal groove.

It is often associated with a tracheo-oesophageal fistula.

Oeosophageal atresia has a high incidence in mothers with polyhydramnios - as high as 85% - and should always be excluded in the baby of mothers with this condition.
