Pharyngo-oesophageal abnormalities are found in a high proportion of patients with globus sensation. This study compares the diagnostic value of static single- and double-contrast radiography of the pharynx and oesophagus with videofluoroscopy and with videofluoroscopy combined with static radiography in these patients. Pharyngeal and oesophagal morphology and motor function were studied in 130 consecutive patients with globus sensation (46 males, 84 females; mean age, 47 years) by means of static single and double-contrast radiography and by videofluoroscopy. Videofluoroscopy revealed significantly more functional and structural abnormalities compared to static radiography. Pharyngeal and/or oesophageal disorders were found in 89 vs. 47 patients(χ2  = 19.82, P = 0.0001), pharyngeal abnormalities in 54 vs. 27 patients (χ2  = 13.5, P <0.0002), and oesophageal abnormalities in 72 vs. 27 patients (χ2  = 28.13, P <0.0001). Videofluoroscopy combined with static radiography revealed significantly more abnormalities than videofluoroscopy alone (X  = 4.23, P <0.05), and assessed mucosal details more reliably than videofluoroscopy alone. The most frequent abnormalities found were nonspecific oesophageal motor disorders, pharyngo-oesophageal sphincter dysfunction, pharyngeal stasis, achalasia, and laryngeal penetration or aspiration of barium. In most patients with globus sensation, pharyngeal and/or oesophageal abnormalities can be detected radiographically. Videofluoroscopy revealed significantly more functional but not morphological abnormalities than did static radiography. Videofluoroscopic studies combined with static radiography had a higher diagnostic value than videofluoroscopic studies alone.
