Delayed systemic allergic dermatitis following Essure insert: A case report

Clinical improvement after Essure® devices removal: a systematic review

PURPOSE

Essure® implant is a permanently implanted minimally invasive birth control device for women (female sterilisation) widely used between 2002 and 2018. Many adverse events were reported by patients. Increasingly removal procedures have been performed in symptomatic patients. However, there is a lack of in-depth studies on clinical improvement after Essure® removal. We aimed to review all clinical studies about symptoms and quality of life (QoL) after removal procedures.

MATERIALS AND METHODS

A review of literature in electronic search in Medline and Embase databases from January 2002 to January 2022 using the following keywords: Essure; Essure removal; quality of life; symptomatology improvement.

RESULTS

Out of 764 articles in the initial database, 18 clinical studies were eligible for inclusion in our literature review. Overall clinical improvement rates after removal ranged from 21% to 98%. All symptoms were less frequent after Essure® removal, although with large discrepancies between studies. Lack of improvement was reported between 1% to 15% of patients. Rate of patients with improvement of QoL after removal ranged from 58 to 98%. The pain was reported as significantly reduced after the surgery.

CONCLUSIONS

In the available literature, Essure® removal in symptomatic patients may improve symptoms and quality of life. This should be discussed in the benefits and risks ratio before deciding on the best option of management.

Safety reporting of Essure medical device: a qualitative and quantitative assessment on the FDA manufacturer and user facility device experience database in 2018

Background

There have been numerous cases of adverse events since the introduction of Essure medical devices for sterilization in 2002. This study analyzed the safety event reports of the Essure reported in the Manufacturer and User Facility Device Experience (MAUDE).

Methods

A retrospective analysis examined the MAUDE reports between Jan-1, 2018, and Oct-31, 2018 and focused on safety reports related to the Essure device. Safety reports were categorized and analyzed by their event type, device problem, patients' symptoms and the level of harm. Of this study cohort, 10% of samples were randomly selected for quantitative analyses. Thematic analysis was conducted for reports included death cases.

Results

A total of 4,994 eligible reports were analyzed. There were ten reports associated with individuals' deaths, and the main themes of safety reports from qualitative analysis were pains, bleeding, surgery, migraine, and infection. Quantitative analysis of 500 randomly selected samples showed that 98% of adverse event reports were associated with different injuries such as surgery, pain, bleeding, hysterectomy, and menorrhagia. Additionally, more than 90% of reports were submitted by the manufacturer.

Conclusion

These findings indicated several safety issues of Essure. More meaningful pre- and post-marketing surveillance and regulation are warranted in the medical device market to ensure safety and effectiveness, including investigating complaints, promptly sharing relevant information with regulators and users, and implementing corrective actions.

Are Adverse Events Attributed to Essure Associated With Nickel Sensitization?

BACKGROUND

Essure is an effective method for hysteroscopic sterilization. Reports of adverse effects, the underlying mechanisms of which are unknown, have increased in recent years.

OBJECTIVE

The aim of the study was to determine whether there is a relationship between adverse events attributed to Essure and nickel sensitization.

METHODS

Patients presenting alleged adverse reactions to Essure were referred for nickel patch testing before removal. Data regarding medical history of nickel sensitization and symptoms attributed to Essure were collected. Dimethylglyoxime spot tests were performed on the explanted Essure. There was a follow-up at 3 months to evaluate whether there is improvement of the symptoms after Essure removal.

CONCLUSIONS

Nickel sensitization via the classic delayed hypersensitivity pathway did not seem to be responsible for adverse events attributed to Essure. Among systemic symptoms reported, extracutaneous symptoms had the highest prevalence. Systemic contact dermatitis to nickel could not be ruled out in one case.
