Not Applicable
Conditions
Diagnostic Yield of Gastric Neoplasia

Device: virtual chromoendoscopy-TB
Device: pCLE-TB
Registration Number
NCT02515721
Lead Sponsor
Shandong University
Brief Summary

Early detection of gastric intestinal metaplasia (GIM) intraepithelial neoplasia (IN), and gastric cancer are essential to improve patients' outcomes. This study aims to compare the diagnostic yield of GIM, IN and early gastric cancer (EGC) by iScan combined probe-based confocal laser endomicroscopy (pCLE) and iScan alone.

GroupInterventionDescription
Virtual Chromoendoscopy -SBvirtual chromoendoscopy-TBPatients will receive virtual chromoendoscopy using iScan. Standard biopsies will be performed on all suspected lesions and standardized loctaions.
pCLE-TBpCLE-TBPatients will receive white-light endoscopic imaging, followed by probe-based Confocal Laser Endomicroscopy scanning on suspected lesions and 5 standardized locations. Then targeted Biopsies will be performed on locations with intestinal metaplasia, intraepithelial neoplasia, and carcinoma.
