Abstract：
This study aimed to compare the effectiveness of oral contraceptives and a levonorgestrel intrauterine system in treating intermenstrual bleeding due to uterine niche. We retrospectively analyzed 72 patients with intermenstrual bleeding due to uterine niche from January 2017 to December 2021, of whom 41 were treated with oral contraceptives and 31 with a levonorgestrel intrauterine system. Post-treatment follow-ups at 1, 3, and 6 months were conducted to compare the efficiency and adverse effects between the two groups. In the oral contraceptive group, the effectiveness rate was higher than 80% at 1- and 3-months post-treatment and higher than 90% at 6 months. In the levonorgestrel intrauterine system group, the effectiveness rates were 58.06%, 54.84%, and 61.29% at 1, 3, and 6 months of treatment, respectively. Oral contraceptives were more effective than the levonorgestrel intrauterine system in treating intermenstrual bleeding caused by uterine niche (p < 0.05).
摘要：
这项研究旨在比较口服避孕药和左炔诺孕酮宫内节育器治疗因子宫生态位引起的经期出血的有效性。我们回顾性分析了2017年1月至2021年12月72例因子宫利基引起的经期出血患者，其中41例接受口服避孕药治疗，31例接受左炔诺孕酮宫内节育器治疗。治疗后随访1、3、6个月,比较两组患者的有效率和不良反应。在口服避孕药组中，治疗后1个月和3个月的有效率高于80%,6个月的有效率高于90%.在左炔诺孕酮宫内系统组中，有效率为58.06%,54.84%,在治疗1、3和6个月时为61.29%，分别。口服避孕药比左炔诺孕酮宫内节育器治疗宫腔隙引起的经期出血更有效（p<0.05）。
