左炔诺孕酮宫内缓释系统在妇科疾病治疗中的作用

背景：左炔诺孕酮宫内缓释系统有很高的避孕可靠性，可对子宫内膜产生明显的抑制作用。目的：阐述左炔诺孕酮宫内缓释系统在妇科疾病治疗中的作用。 方法：由第一作者检索CBM、PubMed数据库(http://www.ncbi.nlm.nih.gov/PubMed)、万方数据库(http://www. wanfangdata.com.cn)及google学术网1990/2010有关左炔诺孕酮宫内缓释系统治疗妇科疾病的文献，排除重复性研究。结果与结论：共保留17篇文献进行归纳总结。结果显示，左炔诺孕酮宫内缓释系统作为释放微量孕激素的宫内缓释系统，可安全、有效地应用于避孕，治疗月经过多、内异症、子宫腺肌病，以及激素替代治疗中对子宫内膜的保护等，对治疗子宫肌瘤引起的月经过多也有良好效果。提示左炔诺孕酮宫内缓释系统治疗妇科疾病效果显著，但还需要大样本、长期的临床研究加以验证。
