ABSTRACT

The authors present their experience with radionuclide transit in the study of esophageal motility using a very simple and easy technique. They have established a normal pattern and analyse their findings in achalasia and probable diffuse esophageal spasm. They review the literature and submit the method as a very important tool for the diagnosis of esophageal motor disorders.
