| Popis: | ABSTRACT Background: Chagas disease causes digestive anatomic and functional changes, including the loss of the myenteric plexus and abnormal esophageal radiologic and manometric findings. Objective: To evaluate the association of abnormal esophageal radiologic findings, cardiac changes, distal esophageal contractions, and complaints of dysphagia and constipation in upper (UES) and lower (LES) esophageal sphincter basal pressure in Chagas disease patients. Methods: The study evaluated 99 patients with Chagas disease and 40 asymptomatic normal volunteers. The patients had normal esophageal radiologic examination (n=61) or esophageal retention without an increase in esophageal diameter (n=38). UES and LES pressure was measured with the rapid pull-through method in a 4-channel water-perfused round catheter. Before manometry, the patients were asked about dysphagia and constipation and submitted to electrocardiography and chest radiography. Results: The amplitude of esophageal distal contraction decreased from controls to chagasic patients with esophageal retention. The proportion of failed and simultaneous contractions increased in patients with abnormal radiologic examination (P |
