文摘目的 运用基于贝叶斯框架的网状Meta分析方法评价口服中成药治疗腹泻型肠易激综合征的疗效及安全性。方法 计算机检索中国知网(CNKI)、万方数据库(Wanfang Data)、维普数据库(VIP)、中国生物医学文献数据库(CBM)、Pub Med、Embase、Web of Science、Cochrane Library数据库,检索有关口服中成药联合常规西医治疗(conventional western medicine treatment,CWMT)腹泻型肠易激综合征的临床随机对照试验,检索时限为自建库至2022年11月15日。采用Cochrance偏倚风险评估工具对纳入研究进行偏倚风险评价,使用Stata14.0和Ge MTC 0.14.3软件进行数据分析。结果 最终纳入51项研究,13种中成药,4468例患者。网状Meta分析结果显示,提高总有效率的前3种最佳方案为补中益气丸(颗粒)+CWMT>乌梅丸+CWMT>乌灵胶囊+CWMT;在改善腹痛积分方面,疗效前3名的方案依次为乌灵胶囊+CWMT>痛泻宁颗粒+CWMT>补脾益肠丸+CWMT=枫蓼肠胃康胶囊(颗粒/片)+CWMT;在改善腹泻积分方面,疗效前3名的方案依次为乌灵胶囊+CWMT>补脾益肠丸+CWMT>痛泻宁颗粒+CWMT;在改善腹胀积分方面,疗效前2名的方案为气滞胃痛颗粒+CWMT>乌灵胶囊+CWMT;在降低不良反应发生率方面,排名前3名的方案依次为补脾益肠丸+CWMT>参苓白术颗粒(散/丸)+CWMT>参倍固肠胶囊+CWMT。结论 与CWMT相比,联合口服中成药治疗腹泻型肠易激综合征可以提高总有效率,改善腹痛、腹泻、腹胀症状,且不会增加不良反应发生率。由于纳入文献质量水平不高,结论仍需更多高质量研究进一步验证。
