In the evaluation of oesophageal function the barium swallow/videofluoroscopy procedure competes very fayourably with other modalities, such as manometry, endoscopy or 24-h pH-metry1, 2. Furthermore the radiological swallow technique is easier to interpret and does not require additional expensive equipment or specialized training. Videofluoroscopy has become a widely accepted method, which allows precise assessment and documentation of oral, pharyngeal, and oesophageal phases of swallowing. [ABSTRACT FROM AUTHOR]
