OBJETIVO: Estudar os achados radiológicos encontrados na seriografia digestiva alta no pós-operatório tardio de cirurgia de Fobi-Capella. MATERIAIS E MÉTODOS: Estudo radiológico de 41 pacientes realizado seis a nove meses após a cirurgia de Fobi-Capella. RESULTADOS: As alterações encontradas foram hérnia hiatal (17%), refluxo gastroesofágico (19,5%) e deslizamento do anel (4,8%). Os achados menos freqüentes foram fístula enterocutânea (2,4%), estenose da anastomose gastrojejunal (2,4%), bezoar (2,4%) e não-visualização do anel em decorrência da sua retirada por intolerância (2,4%). As alterações anatômicas da cirurgia foram claramente demonstradas. CONCLUSÃO: O estudo foi capaz de demonstrar as alterações anatômicas e as complicações da cirurgia de Fobi-Capella.

Breast MRI is effective in detecting residual lesions after RFA in patients with IDC.

ObjectiveTo identify and classify the radiographic patterns of megaesophagus in Chagas disease, as seen on esophagograms and chest X-rays.Materials and MethodsThis was a prospective study of 35 patients diagnosed with esophageal disease 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 dilatation and impairement of esophageal motility. We subsequently correlated that ranking with the chest X-ray findings: gastric air bubble; air-fluid level; and mediastinal widening.ResultsAmong the 35 patients, the esophageal disease 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 patients with grade I esophageal disease showed changes on chest X-rays. In two of the three patients with grade II disease, there was no gastric air-bubble, although there were no other findings in any of the grade II patients. Of the 19 patients with grade III disease, 15 had abnormal findings on X-rays. All four patients with grade IV disease showed abnormalities.ConclusionThe use of Rezende's classification is feasible, encompassing findings ranging from the subtle changes that characterize the initial phases of esophageal disease to the complete akinesia seen in dolicomegaesophagus. Chest X-ray findings are more common in patients with advanced stages of the disease and indicate the degree of esophageal involvement in Chagas disease.
