Essure procedure consists in the placement of two coils in the intramural segment of Fallopian tubes by hysteroscopic causing a fibrosis reaction that unleashes a physiological obstruction. Hysterosalpingography, until today, is the gold standard checking the success of this method of sterilization.
Determining if a scan at three months postimplantation is sufficient to confirm the correct positioning of the device.
Descriptive study with 61 patients undergoing definitive hysteroscopic sterilization to validate transvaginal ultrasound as a technique to determine the effectiveness of the method.
There were placed 120 devices, of which 117 (97'5%) were visible by ultrasound. Comparing ultrasound findings with gold standard, we obtain that in cases of proper bilateral implantation by hysterosalpingography, with ultrasound we diagnosed the 81 '13%; in cases of correct unilateral implantation we detected 75% with ultrasound, except one patient who was considered proper placement of the coil by ultrasound but hysterosalpingography reported that it was misplaced and the Fallopian tube was permeable.
Transvaginal ultrasound is an appropriate method to confirm the correct position of intratubaric Essure devices, its safety, low cost and reproducibility. However, our study cannot replace the hysterosalpingography as gold standard.
Essure手术是通过宫腔镜在输卵管壁内部段放置两个线圈，引发纤维化反应，从而形成生理性梗阻。直至今日，子宫输卵管造影术仍是检查这种绝育方法是否成功的金标准。
确定植入后三个月的扫描是否足以确认装置的正确定位。
对61例行确定性宫腔镜绝育术的患者进行描述性研究，以验证经阴道超声作为确定该方法有效性的一项技术。
共放置了120个装置，其中117个（97.5%）可通过超声显影。将超声检查结果与金标准进行比较，我们发现，在子宫输卵管造影显示双侧植入正确的病例中，超声诊断出81.13%；在单侧植入正确的病例中，超声检测出75%，但有一名患者，超声认为线圈放置正确，而子宫输卵管造影显示其位置错误且输卵管通畅。
经阴道超声是确认输卵管内Essure装置正确位置的一种合适方法，具有安全性、低成本和可重复性。然而，我们的研究不能取代子宫输卵管造影术作为金标准。
