Abstract
Scintigraphic technique was used to study esophageal transport of a solid bolus in 16 patients with dysphagia but with normal manometry, and negative acid perfusion tests, acid clearing tests, and pH reflux tests. Radiology performed on 14 of the 16 patients showed no evidence of organic lesions. Half the patients had abnormal findings at scintigraphy, with either bolus retention in the upper part of the esophagus or prolonged transit time as compared to a group of 20 asymptomatic subjects. Scintigraphy can be regarded as a valuable complement in the objective documentation of dysphagia when other diagnostic methods fail.
