目的:探讨非溃疡性消化不良患者十二指肠胃反流(duodenogastricreflux,DGR)与临床症状及胃黏膜炎症间的关系。
方法:用Bilitec2000型便携式胆红素监测仪对25名健康人及53例有腹痛、腹胀等症状的非溃疡性消化不良患者进行24小时胃内胆红素监测,并行临床症状评分、胃镜检查及组织活检,分析胆汁反流严重度与症状、镜下表现及组织病理改变之间的关系。
结果:24小时胆汁反流总时间百分率在健康人组和消化不良患者中分别为(3.6±1.9)%及(18.6±9.6)%(P<0.05)。消化不良患者病理性DGR的检出率为53%(28/53),胆汁反流总时间百分率与临床症状评分之间不相关(r=0.134,P>0.05);生理性和病理性DGR的幽门螺杆菌感染率(48%比57%)比较无统计学差异(P>0.05);生理性和病理性DGR胃窦部糜烂的发生率分别为20%(5/25)和68%(19/28)(P<0.05);黏液湖或黏膜胆染发生率分别为12%(3/25)和54%(15/28)(P<0.05);胃镜发现的18例黏液湖或黏膜胆染者,被便携式胆红素监测仪确定为DGR者15例(83%)。组织病理检查发现:在幽门螺杆菌阴性患者中,胆汁反流总时间百分率与胃窦部慢性炎症(r=0.478,P<0.01)、活动(r=0.779,P<0.01)及萎缩(r=0.462,P<0.05)呈正相关,黏膜肠化生的程度则不论在幽门螺杆菌阳性(r=0.545,P<0.05)或阴性者(r=0.582,P<0.05)均与胆汁反流总时间百分率呈正相关。
结论:53%(28/53)的非溃疡性消化不良患者存在病理性DGR,DGR的严重度与临床症状评分之间不相关,胆汁反流在胃黏膜损害中起重要作用。
