目的探讨活检部位与Ｈｐ的检出率，观察内镜下喷洒美蓝治疗Ｈｐ的效果．方法选择内镜下诊断的慢性萎缩性胃炎或其它胃病伴有萎缩改变及肠上皮化生改变者２６８例．对其萎缩面的形态、肠上皮化生的特点进行分型．结果闭合型萎缩性胃炎以窦部Ｈｐ检出率高，而开放型以体部检出率高（Ｐ＜００１），肠上皮化生广泛的部位，Ｈｐ检出率低（Ｐ＜００１）．美蓝喷洒法与口服法比较具有相同治疗效果．结论内镜下取活检的部位及肠上皮化生的程度可影响Ｈｐ检出率．喷洒美蓝治疗Ｈｐ法，经济、效果好、副作用少．
Objective To investigate the detection rate of biopsy site and Hp and observe the effect of endometrial administration of methylene blue on Hp. Methods Select endoscopic diagnosis of chronic atrophic gastritis or other gastric problems associated with atrophy and intestinal metaplasia change in 268 cases. Its shrinkage surface morphology, intestinal metaplasia characteristics of the type. Results In the atrophic gastritis, the detection rate of Hp in the sinus was high, but in the open type, the detection rate of Hp was high (P <001) and the detection rate of Hp was low in the extensive part of the intestinal metaplasia 01). American blue spray method and oral method have the same treatment effect. Conclusion The location of biopsy under endoscopy and the degree of intestinal metaplasia can affect the detection rate of Hp. Spraying methylene blue treatment Hp method, economy, good effect, less side effects.
