In patients with suspected oesophageal symptoms, flexible endoscopy and/or contrast radiology (eg. barium swallow) should be performed before considering manometric assessment.

Oesophageal manometry is indicated for the evaluation of dysphagia not definitively diagnosed by means of endoscopy and/or radiology, as manometry is the most accurate method for diagnosing the well-characterised primary oesophageal motility disorders (achalasia and diffuse oesophageal spasm). Oesophageal manometry is the most accurate method for pH electrode placement.
