Characterization of the Essure System Tubal Sterilization Using Ultrasound and X-Ray
Completed
Conditions studied: Tubal Sterilization
In brief
Tubal sterilization is the most prevalent form of contraception in the United States and the world. Currently, approximately half of these are performed with a laparoscope and half through a mini-laparotomy after delivery. Micro-insert hysteroscopic sterilization system received FDA approval for elective sterilization in 2003. Compared to other forms of female sterilization, this procedure is minimally invasive and does not require entering the abdominal cavity. In addition, it is at least as effective in preventing pregnancy as other forms of tubal occlusion. Given the distinct advantages of this method, it could become the preferred method of tubal sterilization for physicians and their patients. Currently, there is no published data concerning the appearance of the micro-inserts system using other imaging modalities that are commonly used in gynecologic practice. As the use of this device becomes more widespread it will be more commonly encountered in radiographic imaging performed as part of routine patient care. The main objective of this study is to provide important descriptive data concerning the ultrasonographic and x-ray appearance of the micro-insert hysteroscopic sterilization device. An additional objective of this study is to identify characteristics on plain film and ultrasound (US) that correlate with tubal occlusion or patency.

You may qualify if…
- Adult patients requesting sterilization
You may not qualify if…
- Unsuccessful placement of the hysteroscopic sterilization system in one or both fallopian tubes. In addition, a patient will not be offered the opportunity to participate in the study if there are any conditions that would preclude attempted placement of the hysteroscopic sterilization system. These include hypersensitivity to nickel-titanium or contrast media, current or recent pregnancy (within the previous six weeks), active genital tract infection, prior tubal ligation, or known congenital uterine malformation.
