Guttural and tracheal and esophageal crevice
In rare instances the throat and a trachea on some extent are not separated from a gullet. The formed guttural and tracheal and esophageal crevice clinically is shown as well as esophageal and tracheal fistula, and only existence of an aphonia allows to suspect the specified defect. It is difficult to establish the diagnosis by means of reitgenokoitrastny research therefore usually resort to endoscopy.
Usually the gullet is squeezed by retrosternal lymph nodes at tuberculosis, histoplasmosis, other purulent processes in lungs, and also at a lymphoma. Partial obstruction of a gullet can be caused by pressure upon it of abnormal vessels of a mediastinum, for example aortic arches.
Duplikatsionny cysts of a gullet can also be the cause of its compression; they are diagnosed at X-ray contrast research. The epithelium of such cysts can come from any department of a digestive tract; cysts are not reported with a gullet cavity if only in the cyst covered by a gastric epithelium there is no ulceration. Two thirds of cysts are located on the right side of a gullet. In rare instances they penetrate through a diaphragm and connect to intestines. Neuroepithelial cysts of a gullet contain glial elements; usually they are accompanied by backbone malformations.
Inborn stenosis of a gullet and mucous membranes of a gullet
These types of pathology meet very seldom. Their embryogenesis, apparently, same, as well as at an atresia. The dysphagy is usually shown at inclusion in a diet of dense food. Treatment is same, as at much more frequent strictures caused by a peptic esophagitis.
