In Mambai, an endemic area for Chagas’ disease, contrast radiography of the oesophagus using 70 mm film was done in 1,145 male and I,184 female individuals. Ages ranged from 4 to 87 years. The patients were positioned in the right anterior oblique position and two films taken, one immediately after ingestion of 75 ml of barium contrast and another 60 seconds later. Seventy six (3.2%) individuals had oesophageal abnormalities of whom 71(7%) were among 1,006 seropositives and 5(0.37%) were among 1,323 seronegatives. Of the 76 patients, 47 (61.8%) were male and 29(38.1%) female. Following the classification of Rezende and colleagues, 48(63.1%), belonged to group 1,18(23.7%), to group II, 5(6.6%) and 5(6.6%) to group IV. The prevalence of oesophageal disease increased with age especially after 30 years, reaching 21.5% in the group over 59 years of age.
