文摘目的 探讨逍遥散加减治疗肝郁脾虚证慢性结石性胆囊炎(chronic calculous cholecystitis,CCC)的临床疗效。方法 随机将2018年12月—2020年6月中国人民解放军联勤保障部队第921医院收治的118例肝郁脾虚证CCC患者分为两组,对照组59例,治疗组59例。对照组给予饮食干预、复方阿嗪米特肠溶片、熊去氧胆酸、非甾体类消炎止痛药等综合治疗,治疗组在对照组基础上加用逍遥散加减辨证治疗,两组疗程均为4周。统计分析两组的中医证候疗效和超声影像学疗效,比较两组治疗前后中医证候积分、健康状况调查简表(the MOS item short from health survey,SF-36)评分、胆囊功能的变化。结果 治疗组的中医证候总有效率94.92%(56/59),明显高于对照组83.05%(49/59),差异有统计学意义(P <0.05);治疗组超声总有效率89.83%(53/59),明显高于对照组74.58%(44/59),差异有统计学意义(P <0.05);治疗后,与对照组比较,治疗组中医证候积分降低,差异有统计学意义(P <0.05),SF-36量表评分升高,差异有统计学意义(P<0.05);治疗组可以增强患者的胆囊收缩功能、缩小胆囊壁厚度,差异有统计学意义(P <0.05)。结论 逍遥散加减治疗肝郁脾虚证慢性结石性胆囊炎可以改善症状,促进胆囊功能恢复,提高生活质量。
