[Sequential esophageal scintigraphy contribution on cardia achalasia diagnosis]. / Contributia scintigrafiei esofagiene secventiale în diagnosticul acalaziei cardiei.

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 golden standard for diagnosis is esophageal manometry. Esophageal scintigraphy is a non-invasive method of exploration: the technique is simple, it lasts five minutes and is more sensitive than the radiologic exam. The esophageal scintigraphy was made in the Nuclear Medicine Laboratory of the Sf. Spiridon Hospital using a gamma scann Diacam--Siemens. The parameters measured with esophageal scintigraphy are: esophageal transit time, residuary radioactivity. Our study included a number of 37 patients with achalasia with ages between 16 and 80 years (the average--47, 3 years). Our conclusions are the same with the data from literature.

[The scintigraphic assessment of the patients suffering from cardia achalasia, treated by pneumatic dilatation]. / Evaluarea scintigrafica a bolnavilor cu acalazia cardiei tratati prin dilatare cu balonas.

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. The pneumatic dilatation with an instrument type Rigiflex is a well/handled and used technique in our clinic. In the study 22 patients were included and we had in view the esophageal transit time and the residuary radioactivity before and after the pneumatic dilatation. We established an important statistical improvement of the data obtained after the dilatation comparative with the data before the treatment (p < 0.01).
