“…The incidence of this disorder is variable among South American countries; it is responsible for up to 90% of achalasia cases in Brazil, 4,5 causes between 18% and 23% of the cases in Argentina, 6,7 and 13% of cases in Chile 8 . Several Brazilian reports indicate that idiopathic achalasia and achalasia related to Chagas disease differ 9,10 . Although we did not observe such differences a recently published report from Argentina found that patients with Chagas disease have acetylcholine M2 receptor circulating antibodies, 11–14 which could be involved in the pathophysiological mechanisms of the disease 15 …”

We review the treatment of esophageal achalasia by means of pneumatic dilatation (PD), analyzing its results and comparing them with those of the literature. We conclude that our personal experience is similar to that of the literature: PD and surgery produce similar results (67-95%), morbidity (2-9.5%), and mortality (0.7-1%); and PD is cheaper than surgery. According to these conclusions, we believe that the decision of the appropriate treatment should be based on a combination of the choice of the properly informed patient and the operator's experience. However, we also conclude that surgery is mandatory in selected cases, such as achalasia associated with hiatus hernia, esophageal diverticula and neoplasia, history of previous PD failure (since in our experience the results after a second PD are very poor), postoperative relapse, and patients with grade IV mega-esophagus according to Resano-Malenchini's classification.

“…Não foram encontradas diferenças entre pacientes com acalásia idiopática e aqueles com doença de Chagas na amplitude das contrações esofágicas (1,15) , destacando-se que nas duas doenças ela está diminuída em relação a pessoas normais (15) , e na amplitude das contrações em faringe, neste local sem diferença com pessoas normais (2) . A proporção de pacientes com contrações de baixa amplitude (inferior a 37 mm Hg) é maior nos pacientes com doença de Chagas do que naqueles com acalásia idiopática (13) . Trabalhos sobre a complacência esofágica também encontraram resultados semelhantes nas duas doenças, ou seja, aumento da complacência (19,24) .…”
