The study investigated the esophageal motility of 98 patients with Chagas' disease and 40 asymptomatic volunteers, with the objective of comparing patients with vigorous achalasia (distal amplitude contractions >/= 37 mmHg) and patients with classical achalasia (amplitude < 37 mmHg). The Chagas' disease patients had normal esophageal radiologic transit (n=60) or esophageal slow transit and retention without dilation (n=38). The manometric method with continuous perfusion was used to study esophageal motility. Comparison of classical and vigorous achalasia showed no difference in duration of contractions, lower and upper esophageal sphincter pressure, proportion of patients with dysphagia, or the number of multipeaked contractions. The number of failed contractions was higher in patients with classic achalasia than in patients with vigorous achalasia. We conclude that the distinction between classical and vigorous achalasia does not seem to be important for the classification of Chagas' disease.
