Prevalence of rectoanal inhibitory reflex in chagasic megacolon.
BACKGROUND Rectoanal inhibitory reflex is not always evident in patients with chagasic megacolon. This may be due to insufficient volumes of air used during insufflation for the manometric examination. AIMS To identify the volume of air necessary to induce rectoanal inhibitory reflex in patients with chagasic megacolon and to observe its prevalence in these individuals. METHODS Rectoanal in...
متن کاملLower oesophageal sphincter response to pentagastrin in chagasic patients with megaoesophagus and megacolon.
Intraluminal manometric studies were performed in 14 chagasic patients with megaoesophagus, 10 chagasic patients with megacolon, and 15 control subjects. Basal lower oesophageal sphincter pressure was 20.27+/-1.16 mmHg (mean+/-SEM) in controls as compared wtih 15.16+/-1.53 mmHg in chagasics with megaoesophagus and 14.38+/-1.50 mmHg in chagasics with megacolon. Dose-response studies to intraveno...
متن کاملAssociation of chagasic megacolon and cancer of the colon: case report and review of the literature.
There are few descriptions of association between chagasic megacolon and colon cancer. We report a case of obstructive abdomen caused by adenocarcinoma of the left colon in chagasic megacolon. A review of the literature revealed 8 cases of this association and, analyzing together the series of findings of cancer in chagasic organomegalies, we found a frequency of 4.8% in megaesophagus and 0.1% ...
متن کاملConstipation Is Related to Small Bowel Disturbance Rather Than Colonic Enlargement in Acquired Chagasic Megacolon
BACKGROUND Constipation is the main symptom of acquired chagasic megacolon. However, a number of patients with Chagas disease without colon involvement also have the same complain. This study evaluated the role of small bowel in constipated patients with Chagas disease with and without megacolon. METHODS Orocecal transit time (OCTT) and oral glucose tolerance test (OGTT) in constipated non-ch...
متن کاملChagasic megaesophagus and megacolon diagnosed in childhood and probably caused by vertical transmission.
Reports on children presenting symptoms compatible with the chronic phase of Chagas disease are sporadic. We report a case of a 7-year-old boy who had megaesophagus and megacolon, both of them a consequence of the trypanosomiasis. The etiology was established by means of laboratory and histological features. Based on epidemiological data, the authors concluded that vertical transmission was the...
