High-definition optical magnification with digital chromoendoscopy detects gastric mucosal changes in dyspeptic-patients

Abstract:

BACKGROUND Accurate detection of gastric infection by Helicobacter pylori (H. pylori) and premalignant lesions are important for effective provision of treatment, preventing the development of gastric neoplasia. Optical enhancement systems with optical magnification improved the identification of mucosal superficial and vascular patterns in patients with dyspepsia. AIM To evaluate an optical enhancement system with high-definition magnification, for diagnosis of normal gastric mucosa, H. pylori-associated gastritis, and gastric atrophy. METHODS A cross-sectional, nonrandomized study from November 2015 to April 2016 performed in a single-tertiary academic center from Ecuador. Seventy-two consecutive patients with functional dyspepsia according to the Rome III criteria, were tested for H. pylori using a stool antigen test and were assigned to an Hp+ group or an Hp− control group. Esophagogastroduodenoscopy …
