Classification of histological severity of Helicobacter pylori-associated gastritis by confocal laser endomicroscopy

Table 3 Confocal laser endomicroscopy and white-light endoscopy in predicting histological changes

Biopsy sites	CLE normal sites1	CLE abnormal sites1
		Inflammation	Atrophy	IM	Early cancer
WLE normal sites	216	173	41	45	0
WLE abnormal sites2	31	83	25	23	2

¹The normal and abnormal sites on confocal laser endomicroscopy (CLE) images were confirmed by histology;

²Abnormal sites include erythema, erosion, nodules and petechiae, etc., with no noticeable lesions such as ulcers or polyps on white light endoscopy (WLE) images. IM: Intestinal metaplasia.
