Abstract

Background Identification of Barrett's esophagus (BE) with the treatment of dysplasia is essential to prevent esophageal adenocarcinoma (EAC). Moreover, determination of BE prevalence is important to define subsequent management strategies. However, precise estimates on BE prevalence from several European countries are lacking. We aimed to determine BE prevalence in a Southern European country. Methods A cross-sectional, multicenter study from November 2019 to February 2020 was performed defining BE as a columnar extent in the distal esophagus greater than or equal to 1 cm with intestinal metaplasia. Results A total of 1550 individuals, 51% male with a mean age of 62 (SD = 15) years undergoing upper endoscopy were included. The overall BE prevalence was 1.29% (95% confidence interval: 0.73-1.85); significantly higher in men [2.05% (1.06-3.04)] vs. women [0.53% (0.01-1.04)]. Of the 20 BE patients, eight were newly diagnosed and 12 were under surveillance. The median extent was C3 (min 0; max 16) M4.5 (min 2; max 16). One patient each had EAC (0.06%) and high-grade dysplasia (0.06%) at the time of endoscopy. There was no difference in prevalence between geographical regions, centers, use of sedation or experience of endoscopists. Considering all reports, 93% used standardized terminology, 23% accurate photodocumentation and 69% photodocumented the esophagogastric junction (EGJ). Furthermore, 80% used Prague classification, 55% Seattle protocol, 60% distance to the squamocolumnar junction, 75% to the EGJ and 40% to the hiatal pinch. When considering only reports with EGJ photodocumentation or Prague classification, the prevalence was 1.78% (0.91-2.64) or 1.03% (0.53-1.53). Conclusion We report for the first time BE prevalence in Southern Europe and report a low overall prevalence in an unselected population. Future studies need to determine progression rates and how to improve quality metrics. Copyright (C) 2021 Wolters Kluwer Health, Inc. All rights reserved.
