放大内镜结合窄带成像技术对慢性胃炎诊断价值的探讨
The value of narrow-band imaging magnification endoscopy for diagnosing chronic gastritis
摘要
Abstract
Objective To explore the clinical value of diagnosing and classifying chronic gastritis by narrowband imaging magnification endoscopy (NBI-ME). Methods NBI-ME was used to observe the gastric mucosa area with suspicious lesions in 41 patients with chronic gastritis diagnosed by endoscopy. Totally 164 biopsy samples were obtained and analyzed. Helicopter pylori (Hp) status was determined by 13C-urea breath test and fast urea enzymes test. Results Non-atrophic gastritis was mostly found in gastric mucosa of type Ⅰ and Ⅱ. Atrophic gastritis was seen in type Ⅲ, Ⅳ and Ⅴ . The incidence of non-atrophic gastritis and atrophic gastritis differed significantly between type Ⅰ and type Ⅲ,Ⅳ as well as between type Ⅱ and type Ⅲ, Ⅳ (P<0.01). Mild atrophy was mostly found in type Ⅲ , moderate atrophy was mainly found in type Ⅳ , and severe atrophy with intestinal metaplasia or dysplasia was mostly found in type Ⅴ and type Ⅵ. Hp infection in gastric antrum mainly appeared in type Ⅲ, Ⅳ and V1. The positive rate of Hp was the highest in type Ⅳ . Type Ⅳ had a significantly different positive rate from that of type Ⅱ (P<0.05), but not from that of type Ⅲ or V1. In gastric body, Hp infection mainly appeared in type Ⅱ , which was significantly different from type Ⅰ (P<0.05). The positive rate of Hp was significantly higher in type Ⅰ and type O of gastric corpus collecting vein than in type R (P<0. 05, P<0.01). Conclusion Diagnosis and classification of chronic gastritis by NBI-ME through observation of the fine mucosal patterns and vascular morphology of the gastric mucosa closely correspond to histopathology. NBI-ME is also valuable for diagnosing Hp infection.关键词
