To evaluate the protocol for confirmation of satisfactory Essure placement using transvaginal ultrasound.
Prospective multicenter cohort study (Canadian Task Force classification II-2).
Outpatient departments of 4 teaching hospitals in the Netherlands.
Eleven hundred forty-five women who underwent hysteroscopic sterilization using the Essure device between March 2005 and December 2007.
Transvaginal ultrasound examination 12 weeks after uncomplicated successful bilateral placement or as indicated according to the transvaginal ultrasound protocol after 4 weeks, and hysterosalpingography (HSG) at 12 weeks to confirm correct placement of the device after 3 months.
The rate of successful placement was 88.4% initially. In 164 women (15%), successful placement was confirmed at HSG according the protocol. In 9 patients (0.84%), incorrect position of the device was observed at HSG. The cumulative pregnancy rate after 18 months was 3.85 per thousand women.
Transvaginal ultrasound should be the first diagnostic test used to confirm the adequacy of hysteroscopic Essure sterilization because it is minimally invasive, averts ionizing radiation, and does not decrease the effectiveness of the Essure procedure.
评估经阴道超声确认满意的 Essure 放置的方案。
前瞻性多中心队列研究（加拿大任务组分类 II-2）。
荷兰 4 所教学医院的门诊部门。
1145 名于 2005 年 3 月至 2007 年 12 月期间接受 Essure 器械宫腔镜绝育的女性。
在无并发症的双侧成功放置后 12 周或根据阴道超声方案在 4 周后进行经阴道超声检查，并在 12 周时进行子宫输卵管造影术（HSG）以在 3 个月后确认器械的正确位置。
最初的成功放置率为 88.4%。根据方案，在 164 名女性（15%）中，HSG 确认了成功放置。在 9 名患者（0.84%）中，HSG 观察到器械位置不正确。18 个月后的累积妊娠率为每千名女性 3.85 例。
经阴道超声应该是用于确认宫腔镜 Essure 绝育充分性的首选诊断测试，因为它具有微创性、避免电离辐射，并且不会降低 Essure 手术的效果。
