[Sequential esophageal scintigraphy contribution on cardia achalasia diagnosis].

Achalasia is a mortality disorder described in 1674 by Willis. It has a small incidence in the general population. The main symptom is dysphagia.

[The scintigraphic assessment of the patients suffering from cardia achalasia, treated by pneumatic dilatation].

The esophageal scintigraphy is a technique used to evaluate the motility and the clearance of the esophagus. The patients with achalasia of the cardia were evaluated, before treating them with pneumatic dilatation and after. The reason is to evaluate the efficiency of the pneumatic dilatation technique in the treatment of esophageal achalasia.
