Oesophageal barium emptying in the discordant and concordant groups of achalasia patients at one month post pneumatic dilation (PD) compared with long term follow up values. Despite reporting near complete symptom relief post PD, the discordant group of patients had poor oesophageal emptying at one month post therapy, which continued long term until the report of symptom failure (n=10). In the concordant group, symptom relief post PD accompanied by complete barium emptying at one month post PD persisted long term in patients available for follow up oesophagram (n=10).
