AB  - Esophageal scintigraphy was developed in order to quantitatively evaluate esophageal transit in patients with a variety of esophageal disorders. The study is performed with orally administered technetium-99m sulfur colloid in water, using a gamma camera on-line to a digital computer. Esophageal transit is expressed as the percent emptying for each of the first 15-sec intervals for 10 min after an initial swallow and at 15-sec intervals after serial swallows. Esophageal transit is significantly decreased in patients with motor disorders of the esophagus, compared to normal controls. In patients with reflux esophagitis, esophageal transit was abnormal when the reflux disease was accompanied by abnormal motor function. The technique we describe is the first quantitative test of esophageal function; it is a useful, sensitive, scintigraphic technique for evaluation of esophageal transit.
