Algorithm of Transvaginal Ultrasound and/or Hysterosalpingogram for Confirmation Testing at 3 Months after Essure Placement.

Study Objective: To evaluate the algorithm of transvaginal ultrasound (TVU) and/or modified hysterosalpingogram (HSG) confirmation testing 3 months after Essure placement to determine if women can rely on the device for permanent birth control.

Design: Interim analysis of an ongoing 10-year, prospective, multicenter, nonrandomized, single-arm, international trial (Canadian Task Force classification II-2).

Setting: Twenty study centers in the United States (n = 12), Canada (n = 1), The Netherlands (n = 6), and Spain (n = 1).

Clinical experience with contrast infusion sonography as an Essure confirmation test.

Objectives: The purpose of this study was to assess the clinical experience, including the feasibility, safety, compliance, and efficacy, of contrast infusion sonography as an Essure (Conceptus Inc, Mountain View, CA) confirmation test.

Methods: A retrospective chart review and telephone survey were conducted at an academic multispecialty group. The study participants were women with Essure intervention who underwent contrast infusion sonography, transvaginal sonography, and hysterosalpingography as Essure confirmation tests.

Contrast infusion sonography in the post-Essure setting.

Study Objective: To compare contrast infusion sonogram (CIS) to hysterosalpingogram (HSG) for use as a 3-month confirmation test after Essure.

Design: Pilot study (Canadian Task Force classification II-2).

Setting: Healthy women in an academic multispecialty group.

Contrast infusion sonography to assess microinsert placement and tubal occlusion after Essure.

Objective: To develop a technique for contrast infusion sonography and assess the possible use in determining microinsert placement and tubal status after Essure sterilization.

Design: Techniques and instrumentation.

Setting: Healthy women in an academic multispecialty group.
