Background and aims: The diagnosis of gastric intestinal metaplasia (GIM) is still challenging. Optical Enhancement technology (OE) may improve the detection of GIM. We compared detection of GIM with OE, acetic acid and the Sydney biopsy protocol in a surveillance population.Methods: Consecutive patients with atrophic gastritis or known GIM were prospectively included. The stomach was examined with high definition whitelight endoscopy, followed by OE or acetic acid with targeted biopsies (1:1 randomisation). Subsequently, five random biopsies were taken according to the updated Sydney system.Results: A total of 154 patients were randomized. Higher proportions of patients with GIM were detected by OE and acetic acid versus random biopsy (60.5% vs 35.5%, 67.1% vs 31.5%, respectively; P < 0.0001 for both comparisons). The combined use of targeted biopsies and random biopsies provides high diagnostic yields for GIM (78.9% in OE group and 83.6% in acetic acid group). In addition, the proportion of extensive GIM was significantly increased when image enhanced endoscopy was used instead of white light endoscopy (P = 0.029, P = 0.048, respectively).Conclusions: OE and acetic acid showed comparable results diagnosing GIM in the study. Targeted biopsies plus random biopsies should be used complementary in high risk populations. (C) 2020 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.
