【摘 要】目的 探讨小肠细菌过度生长与肠易激综合征发病中的关系。方法 用乳果糖氢呼气试验测定49例腹泻及便秘型肠易激综合征病人口-回盲瓣通过时间,并了解其阳性发生率;对其中10例阳性者给普瑞博思治疗1周,进行治疗前后比较。结果 在肠易激综合征病人中腹泻及便秘型口-回盲瓣通过时间较对照组延长(P<0.05),阳性发生率无差别(P>0.05),治疗后口-回盲瓣通过时间改善明显(P<0.05),症状改善。结论 小肠功能紊乱可导致小肠细菌过度生长,并可能是肠易激综合征发病因素之一。 【关键词】肠易激综合征 小肠细菌过度生长 中图分类号:R5 文献标识码:A 文章编号:1005-2194(2000)11-0656-02

【Abstract】Objective To study the relationship between the irritable bowel syndrome and bacterial overgrowth in the intestines.Methods Forty-nine cases of irritable bowel syndrome presenting as diarrhea or constipation were tested by the lactose-functose hydrogen breath test to determine the oral-cecal passage time and positive rate was noted.Of the cases with positive tests ten were selected for treatment with prepulsid for one week,and the pre-and post-treatment passage times were compared.Results In regard to passage time both diarrhea and constipation types of the irritable bowel syndrome showed prolongation compared with controls(P<0.05),no difference in the positive rates(P>0.05),and improvement after treatment compared with pre-treatment,diarrhea was also improved by treatment.Conclusion Intestinal dysfunction can lead to bacterial overgrowth in the intestines,which can be a cause of the irritable bowel syndrome. 【Key words】Irritable bowel syndrome(IBS) Intestinal bacterial overgrowth
肠易激综合征是一组发病机制不明的征候群,特征是肠道功能的易激性,可能与精神因素及肠道动力紊乱有关[1]。我们于1996~1998年对49例肠易激综合征的病人进行了乳果糖氢呼气试验,以观察其小肠细菌过度生长的情况,现将结果报告如下。
1 对象与方法 本院门诊及消化病房住院病人,符合“罗马标准”[2]的病人49例,男性23例,女性26例,年龄22~67岁,平均44岁,除外消化道疾病及慢性肺功能不全,肠镜或钡餐造影检查正常,粪便常规检查正常。其中腹泻型13例(腹痛,大便次数增多,75%以上为稀便或水样便,病程3个月至10余年),便秘型13例(腹痛,排便费力,粪便干结,每周少于2次,病程3个月至1[1] [2] 下一页 上一个医学论文: 腺相关病毒和人 下一个医学论文: 感染性疾病是不明原因长期发热的重要病因
