健脾调肝温肾方治疗腹泻型肠易激综合征的临床研究

目的观察肝脾肾同调法治疗腹泻型肠易激综合征(diarrhea-predominant irritable bowel syndrome,IBS-D)疗效并探讨其机制。方法选择80例IBS-D患者进行前瞻性随机、西药治疗平行对照的临床试验。治疗组和对照组各40例,治疗组口服健脾调肝温肾方,对照组口服匹维溴铵片。疗程为4周。于治疗前后观察并记录腹痛或腹部不适、腹胀、大便次数、大便性状及排便急迫感情况并检测直肠敏感性。停药4周后对治愈和显效患者进行随访。结果治疗组脱落3例,对照组脱落4例。腹痛或腹部不适、腹胀、大便次数、大便性状及排便急迫感记分两组治疗前比较,差异均无统计学意义(P0.05);两组各症状终点记分与基线比较差异均有统计学意义(P0.05)。黏液便的改善治疗后两组间记分差异有统计学意义,治疗组优于对照组(P0.01)。综合疗效:符合方案集(PPS):治疗组痊愈率为24.3%(9/37),总有效率为81.1%(30/37);对照组分别为19.4%(7/36),80.6%(29/36);金分析集(FAS):治疗组的痊愈率为22.5%(9/40),总有效率为80.0%(32/40);对照组分别为17.5%(7/40),77.5%(31/40),两组比较,差异无统计学意义(P0.05)。随访结果:对两组痊愈和显效的病例随访,治疗组和对照组分别有4例和12例复发或加重,两组比较,差异有统计学意义(P0.01)。直肠敏感性:治疗后两组直肠感知阈值、排便阈值和疼痛阈值均有改善,与本组治疗前比较,差异有统计学意义(P0.05),两组间比较,差异无统计学意义(P0.05)。结论健脾调肝温肾方治疗IBS-D有效,且改善黏液便方面优于匹维溴铵,远期疗效也优于匹维溴铵。其治疗机制可能是通过调整肠道敏感性而发挥作用。
