[Dynamic imaging in diagnosis of dysphagia and globus sensation].
BACKGROUND
Videofluoroscopy has gained high significance for the evaluation of deglutition disorders. Imaging alone cannot clarify whether the subjective symptom is represented morphologically or whether it is the substrate of a functional disorder.


METHODS
The videofluoroscopies of 101 patients with dysphagia (n = 55) and globus pharyngitis (n = 46) were evaluated. Morphologic abnormalities were registered as well as sequential movement patterns. These data were compared with clinical and endoscopic findings.


RESULTS
In 87% of the dysphagia and 74% of the globus patients videofluoroscopy revealed pathologic findings. Functional disorders were seen significantly more often than morphologic abnormalities. Highest incidence was found for cricopharyngeal dyskinesia (42%). Hypopharyngeal pouches and degeneration signs of the cervical spine with bolus impression less than 40% are common but functionally not important. Additional esophago-gastroduodenoscopy was pathological in 83% in the dysphagia group and 96% in the globus group.


CONCLUSIONS
Videofluoroscopy is indispensable for the differential diagnosis of dysphagia and globus sensation, especially for the detection of functional disorders in the pharyngoesophageal segment thus documenting the dynamic aspect of deglutition. Videofluoroscopy should be completed by a gastroenterologic examination in order to improve diagnosis.
