Role of cineoesophageal scintigraphy in primary and secondary oesophageal motility disorders. About a 12000 radionuclide transit study experience

Cineoesophageal scintigraphy (COS) and evaluation of oesophageal motility disorders. A 12 000 COS experience with 99mTC-sulfur colloid radiolabeled liquids is detailed. Functional qualitative and quantitative isotopic imaging parameters describe the propulsion abnormalities: mainly achalasia, diffuse esophageal spasm, nutcracker esophagus, non-specific motor disorders, systemic sclerosis, diabetes. Respective advantages and drawbacks of manometry and scintigraphy are discussed. Manometry only can measure pressures, scintigraphy only can measure bolus propulsion by peristaltic waves. Physiological and comfortable conditions, sensitivity, quantitative functional imaging, evidence of lung aspiration when swallowing advantage. (authors). 117 refs., 14 figs., 3 tabs
