Abstract
目的 观察左炔诺孕酮宫内缓释系统(LNG-IUS)用于治疗子宫内膜异位症(EM)及子宫腺肌病(AM)相关疼痛和防止复发的疗效.方法 EM患者21例,AM患者12例,于保守性手术后即刻,或单纯疼痛复发后放置LNG-IUS,EM患者中有4例在放置前注射促性腺激素释放激素激动剂(GnRHa),AM患者中有5例放置前注射GnRHa.以放置LNG-IUS前后自身对照,比较疼痛视觉模拟评分(VAS)、血清生殖激素和CA125水平,随诊记录阴道出血等副反应的发生情况;放置前注射GnRHa者与单纯放置者比较出血模式的差异.结果疼痛复发后单纯放置LNG-IUS的5例EM患者,VAS评分由放置前的(8.09±0.21)降至(1.64±1.12)分,两者比较,差异有统计学意义(P=0.042);5例单纯放置LNG-IUS的AM患者,VAS评分由(8.41±1.59)降至(3.99±3.87)分,两者比较,差异无统计学意义(P=0.068).所有患者于随访期限内,仅2例患者分别出现疼痛或病灶复发,其余患者无疼痛或病灶的复发.放置LNG-IUS后有30例患者完成了初次随诊,初次随诊时间平均为5个月,月平均出血天数18.6 d,以不规则点滴出血为主;放置LNG-IUS前是否加用GnRHa的患者月平均出血天数分别为(19±6)和(18±6) d,两者比较,差异无统计学意义(P=0.089).随诊满1年时,22例患者转为每月规律性阴道出血,月平均出血天数8 d.结论 LNG-IUS能有效控制EM和AM相关疼痛并延缓复发,不规则和(或)点滴阴道出血是最显著的副反应,放置前注射GnRHa对出血的改善效果欠佳。
