BACKGROUND & AIMS: The diagnosis and management of Barrett's esophagus (BE) are controversial. We conducted a critical review of the literature in BE to provide guidance on clinically relevant issues. METHODS: A multidisciplinary group of 18 participants evaluated the strength and the grade of evidence for 42 statements pertaining to the diagnosis, screening, surveillance, and treatment of BE. Each member anonymously voted to accept or reject statements based on the strength of evidence and his own expert opinion. RESULTS: There was strong consensus on most statements for acceptance or rejection. Members rejected statements that screening for BE has been shown to improve mortality from adenocarcinoma or to be cost-effective. Contrary to published clinical guidelines, they did not feel that screening should be recommended for adults over age 50, regardless of age or duration of heartburn. Members were divided on whether surveillance prolongs survival, although the majority agreed that it detects curable neoplasia and can be cost-effective in selected patients. The majority did not feel that acid-reduction therapy reduces the risk of esophageal adenocarcinoma but did agree that nonsteroidal antiinflammatory drugs are associated with a cancer risk reduction and are of promising (but unproven) value. Participants rejected the notion that mucosal ablation with acid suppression prevents adenocarcinoma in BE but agreed that this may be an appropriate strategy in a subgroup of patients with high-grade dysplasia. CONCLUSIONS: Based on this review of BE, the opinions of workshop members on issues pertaining to screening and surveillance are at variance with published clinical guidelines. 相似文献

Central adiposity and risk of Barrett's esophagus 总被引:7,自引:0,他引:7
BACKGROUND AND AIMS: Aside from chronic reflux, the etiology of Barrett's esophagus (BE) remains largely unknown. This case-control study investigated body mass index (BMI), central adiposity, and cigarette smoking and risk of BE. METHODS: Washington residents newly diagnosed with specialized intestinal metaplasia on at least 1 of 4 esophageal biopsy specimens taken at community gastroenterology clinics (cases [n = 193]) were compared with matched population controls (n = 211). Case subgroups included those with any visible columnar epithelium (visible BE) and those with at least 2 cm of columnar epithelium (long-segment BE [LSBE]). Interviewers conducted personal interviews and took anthropometric measurements. RESULTS: All measures of central adiposity were strongly related to BE risk, particularly for LSBE. For the high category of waist-to-hip ratio (WHR), the adjusted odds ratios were 2.4 (95% confidence interval [CI]: 1.4-3.9) for all cases, 2.8 (95% CI: 1.5-5.1) for visible BE, and 4.3 (95% CI: 1.9-9.9) for LSBE. In contrast, the associations with BMI were weaker. When BMI and WHR were modeled simultaneously, the associations with BMI were greatly attenuated, whereas those with WHR remained strong. Further adjustment for frequency of heartburn did not change these results. Cigarette smoking moderately increased risk but with no evidence of a dose-dependent response or increasing strength by case group. CONCLUSIONS: These observations indicate the importance of identifying the mechanisms underlying obesity's role in BE and esophageal adenocarcinoma, and suggest that weight loss might be a fruitful approach to the prevention of these diseases. 相似文献

BACKGROUND & AIMS: Barrett's esophagus (BE) is associated with esophageal adenocarcinoma, the incidence of which has been increasing dramatically. The prevalence of BE in the general population is uncertain because upper endoscopy is required for diagnosis. This study aimed to determine the prevalence of BE and possible associated risk factors in an adult Swedish population. METHODS: A random sample (n = 3000) of the adult population (n = 21,610) in 2 municipalities was surveyed using a validated gastrointestinal symptom questionnaire (response rate, 74%); a random subsample (n = 1000; mean age, 53.5 years; 51% female) underwent upper endoscopy. Endoscopic signs suggestive of columnar-lined esophagus (CLE) were defined as mucosal tongues or an upward shift of the squamocolumnar junction. BE was diagnosed when specialized intestinal metaplasia was detected histologically in suspected CLE. RESULTS: BE was present in 16 subjects (1.6%; 95% confidence interval, 0.8-2.4): 5 with a long segment and 11 with a short segment. Overall, 40% reported reflux symptoms and 15.5% showed esophagitis; 103 (10%) had suspected CLE, and 12 (1.2%) had a visible segment > or = 2 cm. The prevalence of BE in those with reflux symptoms was 2.3% and in those without reflux symptoms was 1.2% (P = .18). In those with esophagitis, the prevalence was 2.6%; in those without, the prevalence was 1.4% (P = .32). Alcohol (P = .04) and smoking (P = .047) were independent risk factors for BE. CONCLUSIONS: BE was found in 1.6% of the general Swedish population. Alcohol and smoking were significant risk factors. 相似文献
