A 65-year-old man, a chronic smoker and alcoholic with a diagnosed adenocarcinoma of the antrum of the stomach, was being further investigated because of dysphagia; endoscopic examination at the referring center showed a polypoid lesion in the mid esophagus. Positron emission tomography (PET) revealed increased uptake of fluorodeoxyglucose in this esophageal lesion. The possibility of a metasta...
BACKGROUND Barrett's esophagus is often asymptomatic and only a small portion of Barrett's esophagus patients are currently diagnosed and under surveillance. Therefore, it is important to develop risk prediction models to identify high-risk individuals with Barrett's esophagus. Familial aggregation of Barrett's esophagus and esophageal adenocarcinoma, and the increased risk of esophageal adenoc...
To determine the accuracy of two-dimensional echocardiography in the identification of congenital anomalies of the aorta, we compared two-dimensional echocardiographic with angiographic results in 261 consecutive infants and children with congenital heart disease (age 1 day to 20 years, mean 3.3 years). Two-dimensional echocardiography was performed and interpreted without knowledge of angiogra...
BACKGROUND The previously reported prevalence of gastric heterotopia in the cervical esophagus, also termed inlet patch (IP), varies substantially, ranging from 0.18 to 14%. Regarding cases with adenocarcinoma within IP, some experts recommend to routinely obtain biopsies from IP for histopathology. Another concern is the reported relation to Barrett's esophagus. The objectives of the study wer...
Patients with Barrett's esophagus are at high risk of progression to adenocarcinoma. A growing, but conflicting body of evidence implicates bile reflux as a contributor to Barrett's esophagus. To investigate whether duodenogastric reflux was associated with an increased risk of Barrett's esophagus, a case-control study of incident Barrett's esophagus was performed. Cases (n=72) were identified ...
The biomechanical and sensory characteristics of the lower esophageal sphincter (LES) and those of the striated and smooth muscle portions of the esophagus have not been compared in humans. Our aim was to determine sensory perception, cross-sectional area (CSA), and biomechanical parameters at different levels of the esophagus. We studied 11 healthy volunteers, using impedance planimetry. Inter...
BACKGROUND AND OBJECTIVE During off-pump coronary bypass grafting, surgical manipulation and dislocation of the heart may cause cardiovascular instability. Monitoring of cardiac output facilitates intraoperative haemodynamic management but pulmonary artery catheters are often considered too invasive. Pulse contour analysis and transoesophageal echocardiography could serve as alternatives, but t...
The significance of finding specialized intestinal epithelium localized to the region of the gastroesophageal junction is unclear. We tested the hypothesis that short segments of specialized intestinal epithelium are a consequence of gastroesophageal reflux disease and are premalignant. Two hundred forty-one patients with reflux symptoms underwent gastroscopy with rigorous biopsy. Barrett's eso...
Barrett esophagus is a change in the normal squamous epithelium of the esophagus to specialized columnar-lined epithelium. Barrett esophagus is of interest to surgeons in that it is associated with gastroesophageal reflux disease (GERD) and is a risk factor for esophageal adenocarcinoma. Beyond that, nearly every other aspect of Barrett esophagus has been an area of controversy among surgeons, ...
BACKGROUND The esophagus may be mobile during a left atrial (LA) ablation procedure for atrial fibrillation (AF). OBJECTIVE The goal of the study was to determine whether the location of the esophagus is stable in patients undergoing a repeat LA ablation procedure. METHODS Forty-two patients underwent repeat LA ablation a mean of 7 +/- 2 months after the initial procedure. Cinefluoroscopic ...
