[Radioisotope study of esophageal transit].

Diagnostics relating to esophageal motility disorders has come into the focus of attention in recent years. A review is made of the possibilities of application of radioisotope esophageal transit measurement. The methods employed and the models of data recording and processing in this field are listed. The value of this procedure in different esophageal disorders is discussed in detail. Two characteristic cases are reported to illustrate the method. It is concluded that measurement of the radionuclide esophageal transit is a noninvasive, simple and safe technique for the screening of esophageal motility dysfunction.
