Abstract

Objectives: To assess the image characteristics of white light endoscopy, BLI magnification endoscopy in gastric dysplastic lesions and Compare BLI magnification endoscopic images with pathological diagnosis. Subjects and methods: Randomized prospective, cross-sectional descriptive study on 40 patients with gastric dysplastic lesions at the Gastroenterology and Hepatology Center - Bach Mai Hospital from June 2022 to July 2023. Results: The average age was 60.2 ± 10.8 years old, the male/female ratio was 1.86/1. Most lesions were in antrum (72.5%), mainly type 0-IIac (55%), average size was 23,7±11.3mm, of which the majority were >10mm (90%), 82.5% of lesions were irregular or absent of microvascular/microtubule structure. With low-grade dysplasia: mainly type 0-IIa (55.6%), 100% had dividing line, the regular rate of microstubule and microvascular structure accounted for the majority (61.1% and 77.8%); with high-grade dysplasia: mainly type 0-IIac (60%), 100% had dividing line, the rate of irregular in microtuble and microvascular structure accounted for the majority (66.7% and 73.3%). The concordance rate between pathological diagnosis before and after intervention was 70%. Conclusions: BLI magnification endoscopy helps increase the rate of accurate biopsy of lesions suspected of gastric dysplasia.
