Occurrence of dolichocolon without megacolon in chronic Chagas disease patients.

Introduction: Since 1970, lengthening of the rectosigmoid has been suspected to be a solitary manifestation of Chagas colopathy.

Methods: To test this hypothesis, opaque enema was administered on 210 seropositive and 63 seronegative patients, and radiographs in the anteroposterior and posteroanterior positions were examined blind to the serological and clinical findings. The distal colon was measured using a flexible ruler along the central axis of the image from the anus to the iliac crest.

[Radiological study on megacolon cases in an endemic area for Chagas disease].

Introduction: A radiological study on the colon of patients from an endemic Chagas disease zone was conducted using the simplified opaque enema technique of Ximenes et al.

Methods: The study involved 291 individuals with a mean age of 48.8 ± 12.

Long-term assessment of the treatment of recurrent tracheoesophageal fistula with fibrin glue associated with diathermy.

Purpose: Recurrent tracheoesophageal fistula (RTF) is a serious common complication of the surgical treatment of esophageal atresia. We report the results of our technique of bronchoscopic treatment of RTF with fibrin glue (Tissucol), with a follow-up of over 1 decade.

Methods: A retrospective review between 1993 and 2004 was conducted, including all patients diagnosed with RTF and treated bronchoscopically with Tissucol, with over 1 year of follow-up.
