Diagnosis

The diagnosis can be made using different modalities. After a complete and thorough history taking, a suspicion often leads to a barium study of upper endoscopy. A barium study would demonstrate a dilated esophagus, often with an air fluid level, and the tapered “bird-beak” narrowing at the distal esophagus.
