Diagnostic yield of the light blue crest sign in gastric intestinal metaplasia: a meta-analysis.

ABSTRACT:

Background

The diagnostic yield of light blue crest(LBC) sign, which was observed by narrow band imaging with magnification endoscopy(NBI-ME), in detecting gastric intestinal metaplasia(IM) has shown variable results.

Objective

We aimed to assess the diagnostic value of LBC under NBI-ME for detecting gastric IM.

Methods

We performed a literature search of the Medline/PubMed, Embase, Web of Science, Science Direct and the Cochrane Library Databases; and a meta-analysis of pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and SROC area under the curve, using fixed- and random-effects models, for the accuracy of LBC-based IM diagnosis.

Results

We initially included 4 articles, but excluded 1 article to counter significant heter
