Case report of failed tubal occlusion using Essuretm pbc (permanent birth control) hysteroscopic sterilisation procedure

Essure microinsert imaging: does abnormal shape on ultrasound predict complications on HSG?

OBJECTIVE

We hypothesize that the shape of the Essure microinsert on ultrasound is able to predict complications evident on hysterosalpingogram (HSG), the accepted gold standard.

METHOD AND MATERIALS

From July 2, 2009 to July 2, 2012, 441 women at our institution received Essure microinsert placement for the purpose of permanent sterilization. 2D and 3D coronal plane transvaginal ultrasounds were performed three months after Essure microinsert placement. Those patients with complications identified on ultrasound, a non-diagnostic ultrasound, or following a difficult insertion were referred for HSG. Patients with both HSG and ultrasound performed were retrospectively selected and anonymized. The ultrasounds were reviewed by a single, blinded radiologist. A total of 122 microinserts in 65 patients were described on ultrasound using a numeric grading system and compared to HSG findings.

RESULTS

Microinsert placement resulted in 37 complications, 31 of which were identified on ultrasound, including uterine and tubal perforations and placement in the endometrial cavity. The sensitivity of Essure microinsert shape on ultrasound in predicting complications, compared with standard HSG, was 94%, with a positive predictive value of 85%; specificity was 95%, with a negative predictive value of 98%. The Kappa coefficient was 0.85 (p < 0.001).

CONCLUSION

Our results suggest that ultrasound may be used as a frontline imaging modality for patients after Essure microinsert placement.

Efficacy of Essure hysteroscopic sterilization--5 years follow up of 1200 women

OBJECTIVE

To assess the efficacy of the Essure hysteroscopic birth control device after 5 years follow up.

STUDY DESIGN

Retrospective analysis of case series.

SETTING

Outpatient hysteroscopy facility in a large teaching hospital.

SUBJECTS

One-thousand three-hundred and twenty-one women who underwent hysteroscopic sterilization with Essure device (Conceptus, Inc., Mountain View, CA) between January 2003 and May 2005.

INTERVENTION(S)

Hysteroscopic tubal sterilization using Essure system.

MAIN OUTCOME MEASURE

Efficacy/effectiveness, failure rate.

RESULTS

Satisfactory insertion was accomplished in the first attempt in 1166 women (97.16%). After the second attempt, successful insertion rate rise to 98.6%. (n = 31, 2.6%). Three pregnancies had been reported after 5 years follow up, which implies an overall absolute rate of 0.25%. This represents a Pearl index of 0.05 after 72,000 months of surveillance. All of them occurred in the first year of use of the microinsert. There has been no unintended pregnancy in the next 4 years.

CONCLUSION(S)

Essure has the lowest Pearl index never published being the most effective permanent birth control system to date. Unintended pregnancies tend to occur in the first year after the insertion, and can be avoided encouraging women to accomplish the protocol.

Hysterosalpingogram: an essential examination following Essure hysteroscopic sterilisation

OBJECTIVES

The aim of this study was to describe our experience of imaging following hysteroscopic sterilisation with the Essure (Conceptus Inc., Mountain View, San Carlos, CA) microinsert, and to underline the importance of a carefully performed follow-up hysterosalpingogram (HSG) in the management of these patients.

METHODS

18 women underwent the procedure and all returned for follow-up HSG. A standard HSG technique was used and views were acquired to establish microinsert position and tubal occlusion.

RESULTS

In 16 of the 18 women, adequate microinsert positioning and bilateral tubal occlusion was present. In one woman, a unilateral microinsert occluded the fallopian tube, whereas the other fallopian tube was ligated with a clip. The final patient underwent two studies; both showed well-positioned microinserts but unilateral free spill from the right fallopian tube. There are no reported pregnancies thus far.

CONCLUSION

Essure sterilisation coils have a unique appearance when radiographed and are an effective means of permanently occluding the fallopian tubes. HSG is a rapid and safe method of confirming satisfactory placement and tubal occlusion. Non-HSG imaging techniques are suboptimal at detecting patent fallopian tubes and expose patients to the risk of an unwanted and potentially complicated pregnancy.

Pregnancy Outcome After Transcervical Hysteroscopic Sterilization

BACKGROUND

Hysteroscopic, transcervical sterilization involves placement of microinserts in tubal ostia. As with any contraceptive method, pregnancy can occur. This case reports the outcome when pregnancy occurred after microinsert placement.

CASE

A multiparous woman presented at 16 weeks of gestation. Hysteroscopic sterilization was performed 2 years earlier, although a postprocedure hysterosalpingogram was not done to verify tubal occlusion. The patient had a normal-term pregnancy. Postpregnancy hysterosalpingogram revealed both microinserts were embedded in the uterine fundus and myometrium.

CONCLUSION

This case demonstrates how pregnancy can occur after hysteroscopic microinsert placement and details how it might be avoided.
