[Conventional X-ray study in the diagnosis of esophageal achalasia and at its treatment stages].

: The paper deals with one of rather common and clinically urgent diseases of the esophagus--esophageal achalasia (EA). By using 173 cases as an example, the authors show a diversity of clinical symptoms and basic X-ray diagnostic criteria for this abnormality. Analysis of the results of clinical and instrumental studies has enabled the authors to differentiate the complicated and uncomplicated forms of the disease, identification of which determines the choice of an algorithm of complex treatment. The paper provides strong evidence that the classical techniques of a conventional X-ray study ensure a valid differential diagnosis of EA and cardioesophageal cancer and evaluates the efficiency of treatments.
