PCLE for the Diagnosis of Gastric Intestinal Metaplasia, Intraepithelial Neoplasia, and Carcinoma

Not Applicable

• Conditions: Diagnostic Yield of Gastric Neoplasia

• 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.
