阴道雌激素用于绝经后女性脱垂手术的多中心随机对照试验
本研究为荷兰22家医院开展的双盲随机安慰剂对照试验,纳入293例拟行初次自体组织脱垂修复术的绝经后POP-Q≥2期女性。受试者术前4–6周开始使用阴道雌三醇乳膏或安慰剂,持续至术后12个月。结果显示雌激素组12个月PGI-I主观改善率为92%,优于安慰剂组80%,且盆腔症状相关生活质量更好,但解剖结果无差异。
要点
- 绝经后脱垂手术围术期加用阴道雌激素可提高术后12个月主观改善率
- 阴道雌激素改善盆腔症状相关生活质量,但不改变解剖复位或再干预率
- 阴道雌激素可作为初次脱垂修复术的辅助治疗选择用于医患共同决策
核心结论
- 围术期阴道雌激素改善绝经后脱垂修复术后12个月患者报告结局和盆底相关生活质量,但不影响解剖结局。
- 支持将阴道雌激素作为绝经后女性初次脱垂手术的辅助治疗选项纳入共同决策。
研究设计与样本
- 双盲、随机、安慰剂对照试验,随访12个月,荷兰22家医院多中心开展。
- 纳入293例绝经后POP-Q分期≥2期、拟行初次自体组织脱垂修复术的女性。
- 随机1:1分配至阴道雌三醇乳膏(1 mg/g)组或外观相同的安慰剂组。
- 术前4–6周开始用药,持续至术后12个月,维持期为每周两次。
- 共57例女性退出研究。
主要发现
- 12个月时雌激素组92%报告PGI-I改善,安慰剂组80%,p=0.02。
- 雌激素组PFDI-20中位评分17分,安慰剂组25分,p=0.03。
- EQ-5D-5L不适或疼痛报告率雌激素组61%,安慰剂组77%,p=0.04。
- 解剖结果、复合手术成功、性功能及再干预率两组无差异。
- 80%参与者表示如果乳膏能带来有意义的健康获益,愿意使用1年。
关键数值与推荐
- 入选标准:绝经后女性,POP-Q分期≥2期,拟行初次自体组织脱垂修复术。
- 干预方案:阴道雌三醇乳膏1 mg/g,术前4–6周开始,术后持续至12个月,维持每周两次。
- 主要结局:术后12个月PGI-I量表报告「明显改善」或「非常明显改善」的比例。
临床怎么用
- 绝经后女性初次脱垂修复术前可考虑启动阴道雌激素治疗并持续至术后12个月。
- 阴道雌激素的获益主要体现在症状改善和生活质量,不能替代解剖复位或减少再干预。
- 该乳膏使用方便,患者接受度较高,可作为共同决策中的辅助选项。
局限性
- 共57例女性退出研究,可能对结果解读产生影响。
- 未观察到解剖结局、性功能及再干预率方面的组间差异。
- 研究人群限定为接受初次自体组织修复的绝经后脱垂患者,外推需谨慎。

ABSTRACT Objective To determine whether vaginal oestrogen therapy improves outcomes after prolapse surgery in postmenopausal women. Design Double-blind, randomised, placebo-controlled trial with 12 month follow-up. Setting Multicentre, 22 hospitals in the Netherlands. Population Postmenopausal women with POP-Q stage ≥ 2 scheduled for primary native-tissue prolapse repair. Methods Women were randomised (1:1) to vaginal oestriol cream (1 mg/g) or identical placebo, started 4–6 weeks preoperatively and continued to 12 months postoperatively (twice-weekly maintenance). Main Outcome Measure Subjective improvement in prolapse symptoms at 12 months postoperatively, defined as “much” or “very much” improved on the Patient Global Impression of Improvement (PGI-I) scale. Results In total 293 women participated, 57 women dropped out. At 12 months, 92% of women in the oestrogen group versus 80% in the placebo group reported improvement on the PGI-I scale (p = 0.02). Pelvic floor-related quality of life was better in the oestrogen group (median score PFDI-20: 17 vs. 25, p = 0.03), and fewer women reported discomfort/pain (EQ-5D-5L: 61% vs. 77%, p = 0.04). Anatomical outcomes, composite surgical success, sexual function and reintervention rates did not differ between groups. The cream was easy to use; 80% would use it for 1 year if it provided meaningful health benefits. Conclusions Perioperative vaginal oestrogen improved patient-reported outcomes and pelvic floor-related quality of life at 12 months, without affecting anatomical outcomes. These findings support discussing vaginal oestrogen as an adjunctive treatment option in shared decision-making with postmenopausal women undergoing primary prolapse surgery.
