Avaliação do megaesôfago por meio do esofagograma

Abstract

Chagas disease is an infection caused by the protozoan Trypanosoma cruzi, transmitted by insects known in Brazil as barbeiros. In its chronic form, it can affect the digestive system, causing megaesophagus. The esophagogram is the main radiological method used for the diagnosis and follow-up of pathology. The objective of this study was to discuss the manifestation of Chagas disease in the chronic phase in Brazil and the performance of radiological examination contrasted in this context. The study was carried out through a literature review, through articles and publications in the Scientific Electronic Library Online database, Lilacs, Ministry of Health, Doctors without Borders and Oswaldo Cruz Foundation, where 1,045 materials were found, 08 of which were used in the study. Data analysis allowed the understanding of the role of esophagogram to investigate the megaesophagus, that the transmission and contagion of disease chagas occurs mainly in vector form in Brazil, and from the radiological point of view differences between the normal and pathological esophagus,example of the ‘bird beak’.
