Brief Summary:
Introduction Traditionally White Light Endoscopy WLE enhanced by biopsies following the updated Sydney system guidelines has been the benchmark for diagnosing and classifying gastric preneoplastic conditions Nevertheless the pronounced interobserver variability and the often weak correlation between endoscopic observations and histopathological results have driven the increasing adoption of virtual chromoendoscopy VCE VCE technologies have demonstrated greater effectiveness in identifying these conditions compared to WLE with Narrow Band Imaging NBI being particularly notable Significantly NBI has played a key role in validating the Endoscopic Grading of Gastric Intestinal Metaplasia EGGIM system However data on the effectiveness of other VCE technologies in this domain is relatively sparse in Europe specifically with Blue Light Imaging BLI despite the promising diagnostic performance demonstrated with this technology
Primary aim to assess the diagnostic accuracy of BLI and to externally validate the applicability of EGGIM classification for staging GIM
Material and methods a multicentric cohort study will be performed involving centres from two European countries Portugal Italy Consecutive patients performing upper gastrointestinal endoscopy will be evaluated by WLE and BLI Random biopsies or targeted plus random biopsies will be performed in order to determine de accuracy of BLI system to detect and stage GIM
Expected results We anticipate that BLI would enable us to assess the extension of GIM without the need for biopsies If observed this would overall improve the upper GI endoscopy accuracy
