BACKGROUND
There is a growing body of literature on placement rates of the Essure® procedure, yet prior studies have not attempted to identify tubal-associated risk factors for placement failures. The current study examines risk markers associated with the inability to deploy the Essure® coils into the tubal lumen using the new ESS305 design.
STUDY DESIGN
We used electronic medical record data to assess risk markers associated with the inability to place the Essure coils in the tubal lumen using the new ESS305 design. A total of 310 attempted procedures between June 14, 2007, and April 29, 2011, were analyzed.
RESULTS
There were 18 tubal failures (5.8%) out of the 310 attempted procedures. A history of a prior sexually transmitted infection (STI) was associated with tubal failure (odds ratio 2.64, 95% confidence interval 1.01-6.90, p=.048).
CONCLUSIONS
We speculate that the observed association between a prior STI and an inability to place the coil was due to a past history of pelvic inflammatory disease.
背景
有关 Essure® 手术放置率的文献越来越多，但先前的研究并未试图确定与放置失败相关的输卵管相关风险因素。本研究使用新的 ESS305 设计，检查与无法将 Essure® 线圈部署到输卵管管腔中相关的风险标志物。
研究设计
我们使用电子病历数据评估了使用新的 ESS305 设计将 Essure 线圈放置在输卵管管腔中时与无法放置相关的风险标志物。分析了 2007 年 6 月 14 日至 2011 年 4 月 29 日期间总共进行的 310 次尝试性手术。
结果
在 310 次尝试性手术中，有 18 次输卵管失败（5.8%）。既往性传播感染（STI）史与输卵管失败相关（优势比 2.64，95%置信区间 1.01-6.90，p=.048）。
结论
我们推测，先前的 STI 与无法放置线圈之间观察到的关联是由于过去的盆腔炎病史。
