OBJECTIVE: To identify and classify the radiographic patterns of megaesophagus in @entity1526 , as seen on esophagograms and chest X- @entity16039 . MATERIALS AND METHODS: This was a prospective study of 35 @entity1 diagnosed with @entity1208 via manometry. The changes found on esophagograms were stratified according to Rezende's classification, divided into four categories (grades I through IV) determined by the degree of @entity384 and impairement of esophageal motility. We subsequently correlated that ranking with the chest X- @entity16039 findings: gastric air bubble; air-fluid level; and mediastinal widening. RESULTS: Among the 35 @entity1 , the @entity1208 was classified as grade I in 9 (25.7%), grade II in 3 (8.6%), grade III in 19 (54.3%), and grade IV in 4 (11.4%). None of the @entity1 with grade I @entity1208 showed changes on chest X- @entity16039 . In two of the three @entity1 with @entity66 , there was no gastric air-bubble, although there were no other findings in any of the grade II @entity1 . Of the 19 @entity1 with @entity66 , 15 had abnormal findings on X- @entity16039 . All four @entity1 with grade IV @entity66 . CONCLUSION: The use of Rezende's classification is feasible, encompassing findings ranging from the subtle changes that characterize the initial phases of @entity1208 to the complete @entity910 seen in dolicomegaesophagus. Chest X- @entity16039 findings are more common in @entity1 with advanced stages of the disease and indicate the degree of esophageal involvement in @entity1526 .
