Pitfalls in the assessment of dysphagia by fibreoptic oesophagogastroscopy.

We present a paper to highlight that the investigation of dysphagia by the standard methods of barium swallow and the now routinely used fibreoptic oesophagogastroscope may miss or inadequately assess pharyngeal and hypopharyngeal causes of dysphagia and to remind that if such a cause is suspected then rigid endoscopy is required to assess or exclude the pathology.
