Characterization of digestive involvement in patients with chronic T. cruzi infection in Barcelona, Spain.

Background: Digestive damage due to Chagas disease (CD) occurs in 15-20% of patients diagnosed as a result of peristaltic dysfunction in some endemic areas. The symptoms of chronic digestive CD are non-specific, and there are numerous confounders. Diagnosis of CD may easily be missed if symptoms are not evaluated by a well trained physician.
