[The recurrence of dysphagia in patients with neuromuscular diseases of the esophagus with normal or low pressure indices in the physiological cardia].

The authors examined 47 patients with recurrent cardiospasm or achalasia of the cardia after dilatation or operations in normal or low esophago-gastric pressure gradient. The findings of clinical, radiological, endoscopic, and esophagomanometric examination of patients are shown. The article discusses the results of drug treatment, pneumatic dilatations, operative interventions in this group of patients. The probable causes of the development of dysphagia in normal values of pressure in the physiological cardia are considered.
