BACKGROUND AND AIMS Hypoxemia can occur during endoscopic retrograde cholangiopancreatography probably induced by the analgesia and sedation done. Moreover the patients prone position difficults the adequate ventilation. The hypoxemia and hypoventilation may not be noticed by nursing staff. A transversal study was used to investigate possible predictive(More)
BACKGROUND Methylene blue has been used to selectively stain areas of specialized intestinal metaplasia in Barrett's esophagus. The sensitivity, specificity, and negative and positive predictive values for the detection of specialized intestinal metaplasia by methylene blue chromoendoscopy were determined in patients with Barrett's esophagus. METHODS(More)
Diagnosis of squamous cell carcinoma of the esophagus is usually late. Staining of the mucosa with Lugol's solution during endoscopy has been suggested to identify early cancer/dysplasia and may improve prognosis. Lugol was tested during endoscopy in 96 asymptomatic subjects at risk for this tumor, who were found to have atypias after exfoliative cytology(More)
UNLABELLED "Matè", a popular hot infusion of a herb (Ilex paraguayensis) drunk in large volumes, is a known risk factor for squamous cell carcinoma of the esophagus and there is a suspicion that high temperature of boiled water used for the infusion may contribute for carcinogenesis. METHODS We measured the temperature of "matè" infusion drunk by a sample(More)
UNLABELLED There is increasing incidence of adenocarcinoma of the esophagus and esophagogastric junction in the USA and Europe, however, data in Brazil are scanty. OBJECTIVE AND METHODS We reviewed all histology confirmed esophageal and esophagogastric junction cancer reports during a 10-year period (1987-1996) obtained by upper digestive endoscopy(More)
Barrett's esophagus (BE) is a complication of gastroesophageal reflux disease, and a premalignant lesion for esophageal adenocarcinoma (EAC). Observational studies suggest that endoscopic surveillance is associated with the detection of dysplasia and EAC at an early stage along with improved survival, but controversies still remain. The management of(More)
