High-definition endoscopy with i-Scan and Lugol’s solution for more precise detection of mucosal breaks in patients with reflux symptoms

BACKGROUND AND STUDY AIMS: Patients with gastroesophageal reflux disease are subdivided into non-erosive (NERD) and erosive reflux disease (ERD). The newly available EPKi processor enables high-definition resolution above HDTV standard (HD+). The aim of the study was to test the efficacy of HD+ esophagogastroduodenoscopy alone and in conjunction with i-Scan (newly developed postprocessing digital filter) and chromoendoscopy (Lugol’s solution) for differentiation of reflux patients. METHODS: The distal esophagus of patients with heartburn was inspected with three imaging modalities. HD+ was followed by i-Scan and 15-mL Lugol’s solution (1.5 %). The esophagus was evaluated for mucosal breaks …
