RESUMO
Os autores apresentam o estudo radiográfico (abreugrafia contrastada para estudo de esofagopatia chagásica) em 1314 pacientes, com 1307 normais, 188 duvidosos e 12 (0,9%) apresentando megaesôfago.
ABSTRACT
Roentgenphotography 70 mm in size, with contrast medium has proved to be a very practical method for mass examination of the esophagus, as the Authors have shown in a Roentgenphography Service, of great movement (36.206 patients in 1 year), in Belo Horizonte, M.G., Brasil. The time of execution of each examination has been prolonged about two minutes, as compared to the conventional method. The operational cost was about one third of conventional retention test, which uses fluoroscopy and 24×30 cm films.
Normal cases, and those with clear retention of contrast medium, usually do not present difficulty in interpretation and offer credible results. However, a minority of cases, which the Authors called doubtful, need better study. Among 1.314 examined patients, 1.307 (84,8%) were normal, 188 (14,3%) were doubtful and 12 (0,9%) were classified as megaesophagus.
The roentgenphotography in lateral position proved to be more advantageous than the anterior oblique position.
Further studies are needed, in order to get better evaluation of doubtful cases.
The method was shown to be practical for epidemiologic study of the esophagopathy of Chagas’ disease and the Aurthors suggest its realization on other regions and health centers of endemic areas.
