A Comparison of pCLE Based Targeted Biopsy and WLE Based Standard Biopsy in Staging the Operative Link on Gastric Intestinal Metaplasia (OLGIM): A Randomized，Cross-over Study

Phase 4

• Conditions: Gastric Intestinal Metaplasia; Biopsy; Confocal Laser Endomicroscopy; Operative Link on Gastric Intestinal Metaplasia

• Registration Number: NCT02930616
• Lead Sponsor: Shandong University

Brief Summary

Gastric intestinal metaplasia (GIM) is an important premalignant lesion for gastric cancer. Precisely surveillance of patients with GIM may result in early detection and improved prognosis. Though important, it is not necessary to recommend surveillance endoscopy for all patients with GIM, since the progression rate to gastric cancer within 10 years is only 1.8% in those patients.
