Description
OBJECTIVES
To compare videofluoroscopy that included a tablet test with impedance planimetry (EndoFLIP(®)) for the evaluation of oesophageal stenosis in patients with dysphagia.
METHODS
In 56 patients, videofluoroscopic examinations following the transit of a 14-mm tablet were retrospectively reviewed and correlated with impedance planimetry findings, a catheter-based method using impedance planimetry to display the oesophageal diameter estimates. Additional findings assessed were the occurrence of symptoms during tablet passage and evaluation of oesophageal motility.
RESULTS
Impaction of the tablet occurred in 31/56 patients; nine showed a moderate delay (2-15 s), three a short delay (<2 s) and 13 no delay of tablet passage. Both methods showed a significant correlation between tablet impaction and oesophageal diameter <15.1 mm, as measured by impedance planimetry (p = 0.035). The feeling of the tablet getting stuck was reported by seven patients, six showing impaction of the tablet (four with an EndoFLIP-diameter < 13 mm, two with a diameter of 13-19 mm) and one showing delayed passage (EndoFLIP diameter of 17 mm).
CONCLUSIONS
Videofluoroscopy and impedance planimetry correlate significantly regarding tablet impaction and residual oesophageal lumen. A standardized 14-mm tablet is helpful in demonstrating oesophageal strictures in dysphagic patients. Triggering of subjective symptoms provides valuable information during a videofluoroscopic study.
KEY POINTS
• A 14-mm tablet can demonstrate oesophagogastric junction narrowing in patients with dysphagia. • Type of passage of a tablet enables estimation of oesophageal luminal diameter. • Videofluoroscopy and impedance planimetry correlate significantly regarding tablet impaction and residual oesophageal lumen.
