Manometric and pharmacological tests have shown that motor abnormalities may occur in the non-dilated colons of chagasic patients. In order to investigate the presence of abnormalities of colonic function in constipated patients with Chagas' disease (ChC) without megaesophagus or megacolon, studies of total and segmental colonic transit time with radiopaque markers were performed on 15 ChC pati...

Serum samples from 152 dogs with a clinical diagnosis of idiopathic megaesophagus without detectable generalized muscle weakness were tested for the presence of antibodies to acetylcholine receptors by immunoprecipitation radioimmunoassay. Positive serum antibody titers (mean, 3.1 nmoL/L; range, 0.77-30 nmoL/L; reference values less than 0.6 nmoL/L) were found in 40 dogs (26%), with German Shep...

BACKGROUND The surgical treatment of advanced megaesophagus has no consensus, being esophagectomy the more commonly used method. Since it has high morbimortality--inconvenient for benign disease -, in recent years an alternative has been introduced: the esophageal mucosal resection. AIM To compare early and late results of the two techniques evaluating the operative time, length of ICU stay; ...

In Mexico, despite the relatively high seroprevalence of Trypanosoma cruzi infection in humans in some areas, reported morbidity of Chagas disease is not clear. We determined clinical stage in 71 individuals seropositive to T. cruzi in the state of Puebla, Mexico, an area endemic for Chagas disease with a reported seroprevalence of 7.7%. Diagnosis of Chagas disease was made by two standardized ...

a 48-year-old man with a giant leiomyoma of the esophagus accompanied by megaesophagus is reported in this paper. he presented with dysphagia and was treated successfully by means of an esopahgogastric resection. the literature is reviewed and the clinical and pathological aspects of this rare tumor are discussed.

Correspondence To the Editor: The dramatic expansion of an esophagus is extremely rare in esophageal diseases. We present a case of megaesophagus associated with atelectasis of the right lung, which showed a typical of achalasia with a " bird's beak appearance ". In order to palliate patient's symptoms, two gastric tubes used. One was inserted into the esophagus for suction residual chymus, the...
