<embryology> A congenital anatomic narrowing in the distal oesophagus that is the result of inappropriate embryological development of the oesophagus, with or without hiatus hernia.

Symptoms include difficulty swallowing and chest pain (under the sternum).

Treatment involves the use of a fibreoptic endoscope using a dilator, balloon or bougie to open up the narrowed segment of the oesophagus.
