Outcome Measures

Primary Outcomes (1)

  • Sensitivity of targeted biopsy within Sydney protocol by using narrow band imaging for Extensive Gastric Intestinal Metaplasia diagnosis

    Sensitivity of targeted biopsy within Sydney protocol by using narrow band imaging for Extensive Gastric Intestinal Metaplasia diagnosis

    4 weeks after completing the enrollment.

Study Arms (1)

Targeted biopsy within Sydney Protocol

EXPERIMENTAL

The patients with history of gastric intestinal metaplasia will be included and using targeted biopsy within Sydney Protocol; both targeted biopsy at suspicious lesions and random biopsy at no suspicious area. * All tissues will be sent to immunohistochemistry as a gold standard. * Sensitivity, specificity,positive predictive value, negative predictive value, accuracy will be calculated.

Diagnostic Test: Targeted biopsy within Sydney protocol

Interventions

Biopsy at suspicious GIM lesions at any area of antrum (both lesser and greater curvature site), body (both lesser and greater curvature site) and incisura. If there is no abnormal mucosa seen at any site, random biopsy will be performed.
