Đánh giá giá trị của nội soi NBI trong chẩn đoán nhiễm khuẩn Helicobacter pylori ở bệnh nhân viêm dạ dày mạn tính

Abstract

Objective: To evaluate the value of narrow band imaging endoscopy for detecting H. pylori infection in chronic gastritis patients. Subject and method: A cross-sectional descriptive study, gastric mucosal patterns seen with NBI were divided into 4 types. Urease test and histology were used for diagnosing H. pylori infection. Result: 89 cases from 01/11/2020 to 30/05/2021. The prevalence of mucosal patterns was 32 (36%) type 1, 34 (38.2%) type 2, 21 (23.6%) type 3, and 2 (2.2%) type 4. Sensitivities for detecting H. pylori infection of type 2 + type 3 + type 4 was 97.22%, specificity was 77.42%, positive predictive value was 83.33%, negative predictive value was 96%. Conclusion: Narrow band imaging endoscopy has high value for predicting H. pylori infection.
