CREMA, Eduardo et al. Manometric evaluation of upper esophageal sphincter in patients with indeterminate form of Chagas' disease. Rev. Soc. Bras. Med. Trop. [online]. 2006, vol.39, n.2, pp.156-158. ISSN 0037-8682. http://dx.doi.org/10.1590/S0037-86822006000200004.
The objective was to study the disorders of upper esophageal sphincter in 37 patients with indeterminate clinical form of Chagas' disease. Eighty (48.6%) patients with synchronic waves were found. The average maximum pressure value of the upper esophageal sphincter was significantly higher in the synchronic group. Subjects with indeterminate clinical form of Chagas' disease may have functional disorders demonstrated by an increase in the pressure of the upper esophageal sphincter.
