X-ray examination of the esophagus

The esophagus is not available x-ray study without the use of contrast media.
The main methods of research of the esophagus are fluoroscopy and radiography. Great perspectives in the study of the characteristics of normal and pathologically changed esophagus opens a study using electronoptical Converter. Particularly valuable in this respect rentgenonegativee enabling detailed study of all stages of functional changes of the esophagus, especially in the human resources review rentgenocontrast.
Reception investigated contrast medium is carried out under the control of the screen. At the moment of passing the contrast of the mixture is carried out to study the picture of the cast of the esophagus, identifies its cross-country ability and character of existing changes. For documentation of the individual stages of the research can be made sighting and observation snapshot and serial images (Fig. 70).

On x-rays produced after passing contrast mix, you can see barium, settled between the folds, making emerges the relief of the mucous membrane of the esophagus. Normal picture of the relief of the mucous membrane of the esophagus is represented mainly reaching a longitudinal folds, very close one to another. The folds of mucous membrane of the esophagus can change its shape and consolidated with stenotic processes of different origin due to congestion and inflammatory changes, both immediate and related. While the picture of the terrain gets mixed views that differ significantly from the usual thin longitudinal folds.
Great importance is the study of pneumorrhagia of the esophagus, which is achieved by simultaneous ingestion together with barium suspension and air. Under such circumstances can clearly be seen and raspravlyaetsya walls, and their outlines, and the character of the changes in the mucosa. Especially valuable data obtained rentgenonegativee (L. E. Caves) (Fig. 71).

With regular research of liquid contrast weight passes into the stomach, do not linger in the esophagus. Thick paste is much slower.
Pathological changes of the esophagus can be accompanied by shifts, extensions and contractions of his crotch.
