摘要
目的 观察胆汁反流对胃内 pH值的影响。方法 对不同浓度胆汁和胃液的混合液及内镜下抽取的黄染和无黄染胃液 ,测定pH和胆红素吸光值 ;2 0例功能性消化不良患者同步监测2 4h胃内pH和胆红素吸光值。结果 胆汁浓度为 2 0 %时吸光值已达 0 90 0 ,而pH仍在 1 0左右 ;浓度为 60 %时pH始上升达 4以上。黄染组pH <4的病例占 80 % ,吸光值为 0 .348±0 .1 31 ,无黄染组pH <4的病例占 81 % ,吸光值为 0 .0 0 8± 0 .0 0 3,pH和吸光值之间无明显相关性。 1 2例有夜间自发性碱波者 8例同步有胆红素吸光值升高 ,8例无夜间自发性碱波者 4例有胆红素吸光值升高。结论 在一定浓度下 ,胆汁反流对胃内 pH值影响较小。
