Analysis of Adverse Events With Essure Hysteroscopic Sterilization Reported to the Manufacturer and User Facility Device Experience Database

Signs and symptoms: Adverse events associated with a sterilization device

Sterilization is now the most common contraceptive method used by women of in the U.S., and sterilization devices have played an important role in its increased popularity. This mixed methods study examines a random sample of 2500 U.S. Food and Drug Administration (FDA) adverse event reports made between 2006 and 2017 about Essure, a sterilization device. Quantitative coding was used to examine patient problems; pain and bleeding were reported most frequently. Qualitative coding analyzed impacts of symptoms on patients' everyday lives and patients' healthcare experiences, including intimate relationships, mothering, and paid employment. Findings suggest that some patients struggled when their reported "subjective" symptoms didn't result in "objective" clinical signs of problems, and when physicians dismissed or deflected their concerns in diagnostic encounters. This paper raises important issues regarding the symptoms patients associated with Essure, the diagnosis of device-driven disease and injury, and the FDA's regulation of medical devices.

Cornual adenomyosis in Essure® device users and in patients hysterectomized for other causes: A retrospective cohort study

OBJECTIVE

To determine whether adenomyosis is present in the cornual portion of hysterectomies of symptomatic sterilization device users and in patients hysterectomized for different benign causes and who presented with pelvic pain and/or menstrual alterations.

METHODS

An observational, analytical, cross-sectional, single-center, retrospective cohort study was conducted in a secondary level hospital. Cohort 1 consisted of women who had Essure® hysteroscopic sterilization devices inserted between 2009 and 2017, who developed gynecologic symptoms (pelvic pain, heavy menstrual bleeding, and/or abnormal uterine bleeding) and who underwent a hysterectomy for explantation of the devices. Cohort 2 consisted of women with the same gynecologic symptoms, who underwent a hysterectomy for other benign causes. All surgeries were performed by the gynecology team between 2018 and 2022. A descriptive and comparative analysis of sociodemographic, clinical characteristics, and pathologic findings between cohorts was made.

RESULTS

In total, 96 patients were studied (cohort 1 included 34 women, cohort 2 included 62 women). Pelvic pain was found to be more frequent in the cohort of Essure users (76.47% vs. 50%, P = 0.012), with a ratio of three times higher in this group (odds ratio 3.25, 95% confidence interval 1.27-8.28). Adenomyosis was more frequently found in the Essure group, both at corporal and cornual portions, the latter being five times higher in this cohort (relative risk = 5.47; 95% confidence interval 1.17-25.64).

CONCLUSIONS

The present study may be the first to describe cornual adenomyosis related to Essure devices. These devices may play a role in the development of adenomyosis and, consequently, pelvic pain. However, causality is difficult to establish.

Assessing the Reproducibility of Research Based on the Food and Drug Administration Manufacturer and User Facility Device Experience Data

OBJECTIVE

This article aims to assess the reproducibility of Manufacturer and User Facility Device Experience (MAUDE) data-driven studies by analyzing the data queries used in their research processes.

METHODS

Studies using MAUDE data were sourced from PubMed by searching for "MAUDE" or "Manufacturer and User Facility Device Experience" in titles or abstracts. We manually chose articles with executable queries. The reproducibility of each query was assessed by replicating it in the MAUDE Application Programming Interface. The reproducibility of a query is determined by a reproducibility coefficient that ranges from 0.95 to 1.05. This coefficient is calculated by comparing the number of medical device reports (MDRs) returned by the reproduced queries to the number of reported MDRs in the original studies. We also computed the reproducibility ratio, which is the fraction of reproducible queries in subgroups divided by the query complexity, the device category, and the presence of a data processing flow.

RESULTS

As of August 8, 2022, we identified 523 articles from which 336 contained queries, and 60 of these were executable. Among these, 14 queries were reproducible. Queries using a single field like product code, product class, or brand name showed higher reproducibility (50%, 33.3%, 31.3%) compared with other fields (8.3%, P = 0.037). Single-category device queries exhibited a higher reproducibility ratio than multicategory ones, but without statistical significance (27.1% versus 8.3%, P = 0.321). Studies including a data processing flow had a higher reproducibility ratio than those without, although this difference was not statistically significant (42.9% versus 17.4%, P = 0.107).

CONCLUSIONS

Our findings indicate that the reproducibility of queries in MAUDE data-driven studies is limited. Enhancing this requires the development of more effective MAUDE data query strategies and improved application programming interfaces.

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.

Analysis of clinical data associated with Essure® sterilization devices: An expanded case series

OBJECTIVES

To evaluate clinical data in women who underwent Essure® hysteroscopic sterilization and to determine whether this sterilization technique plays a role in developing new-onset symptoms.

STUDY DESIGN

An observational, retrospective, single-center study. It was conducted in a secondary level hospital. It included 804 women who had Essure® hysteroscopic sterilization from 2009 to 2017. Charts from these women were reviewed from June 2009 to November 2019, searching for the development of gynecological symptoms (pelvic pain and bleeding disorders) and non-gynecological symptoms (bloating, joint pain, fatigue, headache, alopecia, allergy and depression). The sample was divided into two groups depending on whether they had developed gynecological symptoms (symptomatic group) or not (asymptomatic group), and a descriptive and comparative analysis was made between them. The impact of the global social alarm in 2015 regarding adverse events attributed to the devices, the development of non-gynecological symptoms, and the treatments required, including conservative and surgical options, were also described.

RESULTS

Out of 804 women who had Essure® devices placed, 541(67.29%) remained asymptomatic, 263(32.71%) developed gynecological symptoms, and 41 of these (15.5% of the total sample) requested Essure® surgical removal. Pelvic pain was the most frequent symptom and the main reason for surgical removal. Bleeding alterations were the second most frequent symptom. Up to 55.89% described the symptoms after the social alarm. Non-gynecological symptoms were statistically significantly more frequent in the symptomatic group.

CONCLUSIONS

More than a half of the women who underwent Essure® sterilization remained asymptomatic. The new-onset symptoms attributed to the devices are the minority and causality is difficult to establish.

IMPLICATIONS STATEMENT

Our research provides new follow-up data about Essure® hysteroscopic sterilization. Association between gynecological symptoms and Essure® devices is difficult to demonstrate and some confounding factors may be implicated. The results we described, may guide and counsel medical-patient decisions for the treatment of symptoms related to the devices, including surgical removal.

Challenges in Removing the Essure® Device

We present a case about Essure^® removal surgery in which the third markers of the device have torn off. The woman needed a second surgery for complete removal of the devices. Fluoroscopy during surgery is a good method to visualize the lost fragments. With fluoroscopy, a hysterectomy is not needed for complete removal. It is important to understand the structure of the device and to be aware of the four radiopaque markers during surgery and their removal.

Symptom related to Essure® and evolution after removal: Outcomes of retrospective cohort

INTRODUCTION

The number of requests for Essure removal has grown continually over recent years. The objective is to describe the symptoms reported after Essure sterilization, methods of removal and results.

MATERIAL AND METHODS

Retrospective and single-centre cohort (Regional university hospital of Lille, France) was conducted. All women, having consulted from December 2016 to February 2019 for symptoms related to Essure insertion, were included. All the symptoms were noted. A second group was created that included patients who underwent Essure removal to evaluate the benefits of surgery on these symptoms.

RESULTS

The study included 98 patients. Most frequent symptoms were musculoskeletal pain (75 %), asthenia (63 %) and pelvic pain (55 %). Fifty-nine patients (60 %) underwent surgery. Surgery appeared beneficial with reduction of symptoms in 60 % of these patients, complete resolution in 33 % and no reduction of symptoms in 7%. Many symptoms were relieved by surgery with an overall decline of 96 % in menorrhagia, 94 % in metrorrhagia and 93 % in dyspareunia. However, other symptoms were not relieved by surgery like 100 % of sleep disorders, 70 % of abdominal pain cases and 57 % of memory impairment cases.

CONCLUSION

Symptoms related to Essure insertion are numerous. Although surgery appears beneficial, some adverse effects remain. Therefore, a preoperative aetiologic assessment and information about risk of surgery failure are important.

Safety and Assisted Reproductive Technology Outcomes of Hysteroscopic Tubal Microinserts Versus Laparoscopic Proximal Tubal Occlusion or Salpingectomy for Hydrosalpinges Treatment

OBJECTIVE

This study sought to answer the following question: What are the complications and assisted reproductive technology outcomes among women with hydrosalpinges managed by hysteroscopic microinsert tubal occlusion compared with women with hydrosalpinges managed by laparoscopic proximal tubal occlusion or salpingectomy?

METHODS

This was a retrospective cohort study conducted from January 2009 to December 2014 at two academic, tertiary care, in vitro fertilization centres in Toronto, Ontario. All patients (n = 52) who underwent hysteroscopic tubal occlusion for hydrosalpinges were identified. Patients who proceeded with embryo transfer cycles after hysteroscopic microinsert (n = 33) were further age matched to a cohort of patients who underwent embryo transfer after laparoscopic proximal tubal occlusion or salpingectomy (n = 33). Main outcome measures were clinical pregnancy rate per patient and per embryo transfer cycle.

RESULTS

Among 33 patients, there were 39 fresh and 37 frozen embryo transfer cycles in the hysteroscopic group (group A); among 33 patients in the laparoscopic group (group B), there were 42 fresh and 29 frozen embryo transfer cycles. The cumulative clinical pregnancy rate in group A and group B was similar (66.7% vs. 69.7%, respectively; P = 0.8). The clinical pregnancy rate per embryo transfer cycle was also similar in both groups (28.9% in group A vs. 32.4% in group B; P = 0.6). There were two incidents of ectopic pregnancy in the laparoscopic group and no ectopic pregnancy in the hysteroscopic group. There were three major complications: tubo-ovarian abscess, distal migration of the coil after microinsert placement, and an acute abdomen following the hysteroscopic procedure.

CONCLUSION

Pregnancy outcomes after hysteroscopic placement of a microinsert for hydrosalpinx management before embryo transfer were comparable to those following laparoscopic proximal tubal occlusion or salpingectomy. However, caution is advised regarding microinsert placement for hydrosalpinges before proceeding with assisted reproductive technology.

Assessment of non-gynecological symptoms before and after removal of the Essure® sterilization device: a 6-month follow-up study

BACKGROUND

Most of the clinical adverse events associated with the Essure® sterilization device have been attributed to incidents during and immediately after device placement (perforation, infection, expulsion). The aim of this study was to prospectively evaluate the prevalence and severity of non-gynecological clinical symptoms (e.g. memory disorders, muscle pain, and impaired vision) in patients before device placement and after device removal.

METHODS

Women who presented at least four non-gynecological clinical symptoms with the Essure® filled out a questionnaire before surgical removal of the device and then 1, 3 and 6 months afterwards. Patients with bleeding (metrorrhagia and menorrhagia) or tube perforation were excluded.

RESULTS

Fifty-two symptomatic women were included in the study and followed up for 6 months. The median (range) time interval between Essure® placement and the first clinical symptom was 13 months (1-60), and the median time interval between Essure® placement and removal was 38 months (12-72). The prevalence of clinical symptoms prior to device removal ranged from 26% (for urinary tract disorders) to 96% (for weakness). The mean±standard deviation intensity (on a 0-to-10 scale) of the symptoms before removal of the Essure® was 8.4±0.4; at 1 month, 3 months and 6 months post-removal, the values had fallen significantly to 4.2±0.6, 4±0.8, and 4.1±1, respectively (P<0.0001 for all the symptoms).

CONCLUSIONS

The observed decrease in symptom frequency and severity following Essure® removal and the persistence of this effect at 6 months suggest that the device should be removed in all symptomatic women.

The Trend, Feasibility, and Safety of Salpingectomy as a form of Permanent Sterilization

STUDY OBJECTIVE

To assess the change in the rate of laparoscopic salpingectomy for sterilization after the release of the November 2013 Society of Gynecologic Oncology Clinical Practice Statement and the January 2015 American College of Obstetricians and Gynecologists Committee Opinion: Salpingectomy for Ovarian Cancer Prevention. We hypothesized there would be an increase in salpingectomy as a percentage of total laparoscopic sterilizations performed without an increase in complications when compared with conventional bilateral tubal ligation (BTL).

DESIGN

A retrospective cohort study.

SETTING

Four university-affiliated hospitals in Houston, TX, and New York, NY.

PATIENTS

All women 21 years or older who underwent interval laparoscopic permanent sterilization between April 2013 and September 2016.

INTERVENTIONS

Sterilization by bilateral salpingectomy or conventional tubal ligation.

MEASUREMENTS AND MAIN RESULTS

There were 454 sterilization procedures identified; 60% were BTLs, whereas 40% were salpingectomies. The rate of use of salpingectomy significantly increased from 5% to 9% in 2013 to 2014 to 78% by 2016. There was no significant difference in intraoperative or postoperative complications or estimated blood loss. The mean procedure time was 54 minutes for salpingectomy compared with 45 minutes for BTL (p <.0001). Salpingectomy was more likely to require 3 ports compared with 2 ports for BTL (p <.0001).

CONCLUSIONS

The Society of Gynecologic Oncology and the American College of Obstetricians and Gynecologists' support of salpingectomy for ovarian cancer prevention increased its use for sterilization. Based on this study, laparoscopic bilateral salpingectomy is a safe method of sterilization without an increase in perioperative risk compared with conventional tubal ligation. Physicians should incorporate these findings and implications when counseling patients regarding contraception and permanent sterilization.

Delayed systemic allergic dermatitis following Essure insert: A case report

Hypersensitivity reaction to the nickel component of the Essure contraceptive micro-insert (Essure) is extremely rare. We present a case of a 41-year-old woman who reported a delayed systemic allergic reaction to the Essure. This is the fourth such case to be reported in the literature.

Four years after Essure insertion, the patient developed systemic contact dermatitis secondary to the nickel component. The Essure was suspected as the cause after a positive allergy-patch test result for nickel. An initial laparoscopic bilateral salpingectomy did not improve her symptoms (likely due to retained microfilament), but a subsequent hysterectomy resulted in complete resolution of symptoms.

Nickel allergy is a rare but serious complication of the Essure and practitioners should be cognisant of its role in hypersensitivity reactions.

•

Hypersensitivity to the nickel component of Essure is an extremely rare occurence.

•

We present the fourth case of systemic contact dermatitis following Essure insert.

•

Subsequent removal of the device led to complete symptom resolution.

Laparoscopic Removal of a Retroperitoneal Hysteroscopic Microinsert Using Fluoroscopy

Perforation during placement of hysteroscopic microinserts for permanent sterilization occurs in approximately .9% to 2.6% of women undergoing the procedure. Most of the time perforation results in intraperitoneal placement of the hysteroscopic microinsert requiring laparoscopy or laparotomy for removal of the device. Herein we present a case of hysteroscopic microinsert perforation with subsequent retroperitoneal identification of the device. This is the first such case to our knowledge of retroperitoneal identification and retrieval of a perforated device that required real-time fluoroscopy during laparoscopy.

Pregnancy following hysteroscopic sterilization at an Urban Abortion Clinic- A case series: Are We looking in the wrong places?

OBJECTIVE

Hysteroscopic sterilization (HS) has become one of the most common permanent contraception methods in the U.S. However, recent evidence suggests that the failure rate may be higher than previously reported. We describe women with a history of HS presenting for abortion at a 3-site urban abortion clinic.

STUDY DESIGN

Retrospective case series of patients with previous HS who presented to a 3-site urban abortion clinic for pregnancy termination from October 2012 to February 2015.

RESULTS

In 28months, 9 patients with prior HS had failure of the method and then an abortion.

CONCLUSIONS

This study identifies a number of failures from a setting previously unaccounted. It suggests that perhaps the failure rate is higher than previously reported. The cases here presented, from a 3-site urban abortion clinic over 28months, almost match and sometimes surpass the number of failures reported in multicenter case series in the literature. Surveys of other abortion clinics in the U.S. and elsewhere might also discover other patients whose HS had failed.

IMPLICATIONS

We identified a number of hysteroscopic sterilization failures at termination of pregnancy at a 3-site urban abortion clinic. We hypothesize that the HS failure rate underestimates the true method failure because previous analysis have excluded cases such as these.

Essure Surgical Removal and Subsequent Resolution of Chronic Pelvic Pain: A Case Report and Review of the Literature

Background. Hysteroscopic tubal sterilization (Essure) is a minimally invasive option for permanent contraception with high reported rates of patient satisfaction. A small percentage of these women subsequently choose to have the tubal inserts removed due to regret or perceived side effects such as late-onset pelvic pain secondary to placement of the Essure device. Case. A twenty-nine-year-old woman G4P4014 presented with a two-year complaint of chronic pelvic pain and dyspareunia after the hysteroscopic placement of an Essure device for sterilization. On reviewing the images of the HSG, it was noted that although tubal occlusion was confirmed, the left Essure coil appeared curved on itself in an elliptical fashion and did not seem to follow the expected anatomic trajectory of the fallopian tube. The patient reported resolution of chronic pelvic pain following laparoscopic removal of Essure device. Conclusion. A misplaced Essure device should be considered in the differential diagnosis of chronic pelvic pain in women who had difficult placement of the device. In addition to demonstrating tubal occlusion, careful examination of the configuration of the Essure microinserts on HSG examination provides valuable information in patients with pelvic pain after Essure placement.

Hysteroscopy and contraception

The Essure method is the only available hysteroscopic sterilisation method. A 4-cm device is placed in the fallopian tubes, which then induces an inflammatory reaction that causes occlusion. The method has a high successful placement rate and high effectiveness, and it can be performed in an office setting without anaesthesia. Three months after the procedure, a confirmation test has to be conducted to assure a correct position of the micro-inserts and tubal occlusion. This test can be performed by hysterosalpingography (HSG), plain X-ray or ultrasound. Pregnancies reported after Essure sterilisation are, in a majority, related to non-adherence to the follow-up protocol or misreading of the confirmation test. A majority of the pregnancies occurred after HSGs that were determined to have been misinterpreted, including missed expulsion or perforation of the micro-insert. Other complications such as ectopic pregnancy and allergic reaction to the micro-inserts seem to have been described to be of low incidence.

Bowel perforation after placement of tubal occlusion contraceptive

BACKGROUND

The tubal occlusion contraceptive provides a hysteroscopic technique for female sterilization. Efficacy of the tubal occlusion contraceptive relies on proper placement within the proximal aspect of the fallopian tubes. As long-term data become available, rates of complications are better defined.

CASE

This is a case of a patient who underwent placement of a tubal occlusion contraceptive. As a result of persistent pain and nausea, imaging was performed and malposition of the tubal occlusion contraceptive was identified. During laparoscopy, bowel perforation at the terminal ileum was diagnosed. Laparoscopic ileocecectomy was performed.

CONCLUSION

There should be a low threshold for evaluation of complications after tubal occlusion contraceptive placement. Although rare, bowel perforation after placement of the tubal occlusion contraceptive can occur. Laparoscopic management should be considered.

Management of perforated essure with migration into small and large bowel mesentery

The Essure permanent birth control system (Conceptus Inc, San Carlos, CA) is currently the only Food and Drug Administration-approved hysteroscopic sterilization method and has been widely accepted as a safe and effective procedure. We present a rare case of tubal perforation, coil fragmentation, and distal migration into small and large bowel mesentery 8 days after the insertion of the Essure device. We describe the successful management of this complication using laparoscopy and intraoperative fluoroscopy. Providers using Essure must be aware of the possibility of fragmentation of the Essure coils. Intraoperative imaging, ideally fluoroscopy, should be strongly considered in the management of Essure migration to ensure localization and full retrieval of Essure material.

Risk of Essure microinsert abdominal migration: case report and review of literature

Purpose

To report a case of Essure microinsert abdominal migration and literature review.

Methods

A 41-year-old woman was counseled to undergo Essure sterilization. The procedure was hampered by the presence of endometrial cavity adhesions, obscuring left tubal ostium. By using microscissors the adhesions were progressively lysed. Since the procedure had become very painful, the patient required general anesthesia. Once adhesion lysis was completed, the tubal ostium was well visible. Both devices were then easily introduced into the fallopian tubes. At the end of the procedure, five coils were visible on the right side and five coils on the left side, as recommended.

Results

The 3-month hysterosalpingogram follow-up suspected abdominal migration of the left device. Laparoscopy confirmed the device displacement in the left lower abdominal quadrant. Both fallopian tubes and the uterus appeared normal. No signs of perforation were detected. The device was embedded into the omentum, but it was easily removed. Bilateral tubal sterilization was performed by bipolar coagulation.

Conclusion

There are only 13 cases, including the present, of Essure abdominal migration in the literature. In most cases, abdominal displacement of the microinsert is asymptomatic and does not induce tissue damage. However, in some cases, it may cause a severe adverse event, requiring major surgery. Therefore, removal of the migrated device should be performed as soon as possible. Moreover, during presterilization counseling, the patient should also be correctly informed about the risk of this rare but relevant complication, as well as about the surgical interventions that could be required to solve it.
