左旋炔诺酮宫内缓释系统治疗子宫腺肌病的临床研究

目的探讨左旋-18甲基炔诺酮宫內缓释系统(LNG－IUS)治疗子宫腺肌病的临床疗效及其副反应。方法对70例子宫腺肌病的患者,宫内放置LNG-IUS治疗,观察月经情况、痛经程度、子宫体积变化及对人体肝功能、血脂等的影响。结果放置LNG-IUS后,月经量显著减少,第1个月为原来的(35±12)%(P<0.01),12个月后为(7±4)%(P<0.01);治疗3个月后子宫体积平均缩小18.6%(P<0.05);痛经显著缓解或完全消失;贫血迅速改善,对人体肝功能、血脂无明显不良副作用。结论LNG-IUS治疗子宫腺肌病疗效显著,安全性好。

Clinical study of levonorgestrel-releasing intrauterine system for adenomyosis

OBJECTIVE: To investigate the clinical efficacy of levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of adenomyosis. METHODS: Seventy patients with adenomyosis diagnosed according to clinical symptoms, magnetic resonance imaging (MRI) findings, laparoscopy and/or color-Doppler ultrasound imaging were treated with LNG-IUS, and the menstrual blood volume, dysmenorrhea, uterine volume, hepatic function and serum lipids were observed and evaluated. RESULTS: In the first month of treatment, the menstrual blood size was reduced significantly to (35-/+12)% of that before treatment (P<0.01), and further to (7-/+4)% in the twelfth month (P<0.01). The average uterine volume was decreased by 18.6% (P<0.05) after the treatment, and dysmenorrhea was obviously relieved or completely disappeared alleviated. The condition of anemia was also improved rapidly, and no obvious side-effects on hepatic function and serum lipids were observed. CONCLUSION: LNG-IUS is an effective and safe therapy for adenomyosis.
