本文报告402例慢性胃炎患者经内镜胃液pH值测定结果,探讨胃液pH值对慢性萎缩性胃炎(CAG)的诊断价值。结果显示:CAG胃液pH值显著高于慢性浅表性胃炎(CSG,P<0.01),在CAG中随着萎缩程度加重,其胃液pH值逐渐增高(P均<0.01),CAG伴肠上皮化生或不典型增生者,其胃液pH值高于单纯CAG患者。结论:胃液pH值测定较内镜直视观察诊断符合率为高,其敏感性、特异性、阴性预测值强,故胃液pH值测定对提高CAG的诊断具有参考价值。
This article reports 402 patients with chronic gastritis endoscopic gastric juice pH measurement results to explore the gastric juice pH value of chronic atrophic gastritis (CAG) diagnostic value. The results showed that the pH value of gastric juice of CAG was significantly higher than that of chronic superficial gastritis (CSG, P <0.01). The pH value of gastric juice increased gradually with the severity of atrophy in CAG (all P <0.01) Health or atypical hyperplasia, the gastric juice pH higher than simple CAG patients. Conclusion: The gastric juice pH value is higher than the diagnostic accuracy of endoscopic observation, and its sensitivity, specificity and negative predictive value are high. Therefore, the determination of pH of gastric juice has the reference value for the diagnosis of CAG.
