Radionuclide Esophageal Transit Study in the Esophageal Motility Disorders
|
|
|
|
|
Abstract
|
|
|
Esophageal motility was evaluated from the analysis of 10 consecutive swallows using liquid bolus containing 0.5 mCi of 99mTc tin colloid. We have reviewed our experience of esophageal transit study in the 20 normal volunteers and 55 patients
with
dysphagia that was not related to mechanical obstruction. The purpose of this study is to measure the esophageal transit in normal subjects and in patients with various esophageal motility disorders. The overall sensitivity and specificity of
radionuclide esophageal transit study in detecting esophageal motor abnormality were compared with manometric results as a gold standard, which were 80% and 100% respectively. Radionuclide transit study is a safe, rapid, noninvasive test and
suitable as
a screening test for esophageal motor disorders.
