Core Tip

Core tip: Patient perception of the level of their dysphagia is only accurate in 48% of patients. It is most accurate for those with pharyngeal pouches and for those with pharyngeal or upper oesophageal pathology which might help guide initial investigations, e.g., to barium swallow. No other patient features or history helps determine patient accuracy. Endoscopists and radiologists should be aware of the importance of carefully examining the whole oesophagus to avoid missing pathology irrespective of a patient’s perceived level of dysphagia.
