2018 Update on contraception

Female permanent contraception is among the most widely used contraceptive methods worldwide. In the United States, more than 640,000 procedures are performed each year and it is used by 25% of women who use contraception.1–4 Female permanent contraception is achieved via salpingectomy, tubal interruption, or hysteroscopic techniques.

Essure, the only currently available hysteroscopic permanent contraception device, approved by the US Food and Drug Administration (FDA) in 2002,5,6 has been implanted in more than 750,000 women worldwide.7 Essure was developed by Conceptus Inc, a small medical device company that was acquired by Bayer in 2013. The greatest uptake has been in the United States, which accounts for approximately 80% of procedures worldwide.7,8

Essure placement involves insertion of a nickel-titanium alloy coil with a stainless-steel inner coil, polyethylene terephthalate fibers, platinum marker bands, and silver-tin solder.9 The insert is approximately 4 cm in length and expands to 2 mm in diameter once deployed.9

Potential advantages of a hysteroscopic approach are that intra-abdominal surgery can be avoided and the procedure can be performed in an office without the need for general anesthesia.7 Due to these potential benefits, hysteroscopic permanent contraception with Essure underwent expedited review and received FDA approval without any comparative trials.1,5,10 However, there also are disadvantages: the method is not always successfully placed on first attempt and it is not immediately effective. Successful placement rates range between 60% and 98%, most commonly around 90%.11–15 Additionally, if placement is successful, alternative contraception must be used until a confirmatory radiologic test is performed at least 3 months after the procedure.9,11 Initially, hysterosalpingography was required to demonstrate a satisfactory insert location and successful tubal occlusion.11,16 Compliance with this testing is variable, ranging in studies from 13% to 71%.11 As of 2015, transvaginal ultrasonography showing insert retention and location has been approved as an alternative confirmatory method.9,11,16,17 Evidence suggests that the less invasive ultrasound option increases follow-up rates; while limited, one study noted an increase in follow-up rates from 77.5% for hysterosalpingogram to 88% (P = .008) for transvaginal ultrasound.18

Recent concerns about potential medical and safety issues have impacted approval status and marketing of hysteroscopic permanent contraception worldwide. In response to safety concerns, the FDA added a boxed safety warning and patient decision checklist in 2016.19 Bayer withdrew the device from all markets outside of the United States as of May 2017.20–22 In April 2018, the FDA restricted Essure sales in the United States only to providers and facilities who utilized an FDA-approved checklist to ensure the device met standards for safety and effectiveness.19 Most recently, Bayer announced that Essure would no longer be sold or distributed in the United States after December 31, 2018 (See “FDA Press Release”).23

FDA press release (July 20, 2018)
"The US Food and Drug Administration was notified by Bayer that the Essure permanent birth control device will no longer be sold or distributed after December 31, 2018... The decision today to halt Essure sales also follows a series of earlier actions that the FDA took to address the reports of serious adverse events associated with its use. For women who have received an Essure implant, the postmarket safety of Essure will continue to be a top priority for the FDA. We expect Bayer to meet its postmarket obligations concerning this device."

So how did we get here? How did the promise of a “less invasive” approach for female permanent contraception get off course?

A search of the Manufacturer and User Facility Device Experience (MAUDE) database from Essure’s approval date in 2002 to December 2017 revealed 26,773 medical device reports, with more than 90% of those received in 2017 related to device removal.19 As more complications and complaints have been reported, the lack of comparative data has presented a problem for understanding the relative risk of the procedure as compared with laparoscopic techniques. Additionally, the approval studies lacked information about what happened to women who had an unsuccessful attempted hysteroscopic procedure. Without robust data sets or large trials, early research used evidence-based Markov modeling; findings suggested that hysteroscopic permanent contraception resulted in fewer women achieving successful permanent contraception and that the hysteroscopic procedure was not as effective as laparoscopic occlusion procedures with “typical” use.24,25

Over the past year, more clinical data have been published comparing hysteroscopic with laparoscopic permanent contraception procedures. In this article, we evaluate this information to help us better understand the relative efficacy and safety of the different permanent contraception methods and review recent articles describing removal techniques to further assist clinicians and patients considering such procedures.

In this section, we present 3 recent studies that evaluate pregnancy outcomes and complications including reoperation or second permanent contraception procedure rates.

Data from France measure up to 3-year differences in adverse outcomes

Bouillon and colleagues aimed to identify differences in adverse outcome rates between hysteroscopic and laparoscopic permanent contraceptive methods. Utilizing national hospital discharge data in France, the researchers conducted a large database study review of records from more than 105,000 women aged 30 to 54 years receiving hysteroscopic or laparoscopic permanent contraception between 2010 and 2014. The database contains details based on the ICD-10 codes for all public and private hospitals in France, representing approximately 75% of the total population. Procedures were performed at 831 hospitals in 26 regions.

Adverse outcomes were divided into surgical, medical, and gynecologic complications (TABLE 1) and were assessed at 3 timepoints: at the time of procedure and at 1 and 3 years postprocedure.

Overall, 71,303 women (67.7%) underwent hysteroscopic permanent contraception procedures and 34,054 women (32.3%) underwent laparoscopic permanent contraception procedures. Immediate surgical and medical complications were significantly less common for women having hysteroscopic compared with laparoscopic procedures. Surgical complications at the time of the procedure occurred in 96 (0.13%) and 265 (0.78%) women, respectively (adjusted odds ratio [aOR], 0.18; 95% confidence interval [CI], 0.14-0.23). Medical complications at the time of procedure occurred in 41 (0.06%) and 39 (0.11%) women, respectively (aOR, 0.51; 95% CI, 0.30-0.89).

However, gynecologic outcomes, including need for a second surgery to provide permanent contraception and overall failure rates (need for salpingectomy, a second permanent contraception procedure, or pregnancy) were significantly more common for women having hysteroscopic procedures. By 1 year after the procedure, 2,955 women (4.10%) who initially had a hysteroscopic procedure, and 56 women (0.16%) who had a laparoscopic procedure required a second permanent contraception surgery (adjusted hazard ratio [aHR], 25.99; 95% CI, 17.84-37.86). By the third year, additional procedures were performed in 3,230 (4.5%) and 97 (0.28%) women, respectively (aHR, 16.63; 95% CI, 12.50-22.20). Most (65%) of the repeat procedures were performed laparoscopically. Although pregnancy rates were significantly lower at 1 year among women who initially chose a hysteroscopic procedure (0.24% vs 0.41%; aHR, 0.70; 95% CI, 0.53-0.92), the rates did not differ at 3 years (0.48% vs 0.57%, respectively; aHR, 1.04; 95% CI, 0.83-1.30).

Most importantly, overall procedure failure rates were significantly higher at 1 year in women initially choosing a hysteroscopic approach compared with laparoscopic approach (3,446 [4.83%] vs 235 [0.69%] women; aHR, 7.11; 95% CI, 5.92-8.54). This difference persisted through 3 years (4,098 [5.75%] vs 438 [1.29%] women, respectively; aHR, 4.66; 95% CI, 4.06-5.34).

UK data indicate high reoperation rate for hysteroscopic procedures

Antoun and colleagues aimed to compare pregnancy rates, radiologic imaging follow-up rates, reoperations, and 30-day adverse outcomes, between hysteroscopic and laparoscopic permanent contraception methods. Conducted at a single teaching hospital in the United Kingdom, this study included 3,497 women who underwent procedures between 2005 and 2015. The data were collected prospectively for the 1,085 women who underwent hysteroscopic procedures and retrospectively for 2,412 women who had laparoscopic permanent contraception procedures with the Filshie clip.

Over the 10-year study period, hysteroscopic permanent contraception increased from 14.2% (40 of 280) of procedures in 2005 to 40.5% (150 of 350) of procedures in 2015 (P<.001). Overall, 2,400 women (99.5%) underwent successful laparoscopic permanent contraception, compared with 992 women (91.4%) in the hysteroscopic group (OR, 18.8; 95% CI, 10.2-34.4).

In the hysteroscopic group, 958 women (97%) returned for confirmatory testing, of whom 902 (91% of women with successful placement) underwent satisfactory confirmatory testing. There were 93 (8.6%) unsuccessful placements that were due to inability to visualize ostia or tubal stenosis (n = 72 [77.4%]), patient intolerance to procedure (n = 15 [16.1%]), or device failure (n = 6 [6.5%]).

The odds for reoperation were 6 times greater in the hysteroscopic group by 1 year after surgery (22 [2%] vs 8 [0.3%] women; OR, 6.2; 95% CI, 2.8-14.0). However, the 1-year pregnancy risk was similar between the 2 groups, with 3 reported pregnancies after hysteroscopic permanent contraception and 5 reported pregnancies after laparoscopic permanent contraception (OR, 1.3; 95% CI, 0.3-5.6).

Finnish researchers also find high reoperation rate

Jokinen and colleagues used linked national database registries in Finland to capture data on pregnancy rate and reoperations among 16,272 women who underwent permanent contraception procedures between 2009 and 2014. The authors compared outcomes following hysteroscopic (Essure), laparoscopic (Filshie clip), and postpartum minilaparotomy (Pomeroy) permanent contraception techniques. According to the investigators, the latter method was almost exclusively performed at the time of cesarean delivery. While there was no difference in pregnancy rates, second permanent contraception procedures were significantly greater in the hysteroscopic group compared with the laparoscopic group (TABLE 2).

WHAT THIS EVIDENCE MEANS FOR PRACTICE
At a glance, these studies suggest that pregnancy rates are similar between hysteroscopic and laparoscopic permanent contraceptive approaches. But, these low failure rates were only achieved after including women who required reoperation or a second permanent contraceptive procedure. All 3 European studies showed a high follow-up rate; as method failure was identified, additional procedures were offered and performed when desired. These rates are higher than typically reported in US studies. None of the studies included discussion about the proportion of women with failed procedures who declined a second permanent contraceptive surgery. Bouillon et al26 reported a slight improvement in perioperative safety for a hysteroscopic procedure compared with a laparoscopic procedure. While severity of complications was not reported, the risk of reoperation for laparoscopic procedures remained <1%. By contrast, based on the evidence presented here, hysteroscopic permanent contraceptive methods required a second procedure for 4% to 8% of women, most of whom underwent a laparoscopic procedure. Thus, the slight potential improvement in safety of hysteroscopic procedures does not offset the significantly lower efficacy of the method.
 

 

Technique for hysteroscopic permanent contraception insert removal

Johal T, Kuruba N, Sule M, et al. Laparoscopic salpingectomy and removal of Essure hysteroscopic sterilisation device: a case series. Eur J Contracept Reprod Health Care. 2018;23(3):227-230.

As reports of complications and concerns with hysteroscopic permanent contraception increase, there has been a rise in device removal procedures. We present 2 recent articles that review laparoscopic techniques for the removal of hysteroscopic permanent contraception devices and describe subsequent outcomes.

Laparoscopic salpingectomy without insert transection

In this descriptive retrospective study, Johal and colleagues reviewed hysteroscopic permanent contraception insert removal in 8 women between 2015 and 2017. The authors described their laparoscopic salpingectomy approach and perioperative complications. Overall safety and feasibility with laparoscopic salpingectomy were evaluated by identifying the number of procedures requiring intraoperative conversion to laparotomy, cornuectomy, or hysterectomy. The authors also measured operative time, estimated blood loss, length of stay, and incidence of implant fracture.

Indications for insert removal included pain (n = 4), dyspareunia (n = 2), abnormal uterine bleeding (n = 1), and unsuccessful placement or evidence of tubal occlusion failure during confirmatory imaging (n = 4). The surgeons divided the mesosalpinx and then transected the fallopian tube approximately 1 cm distal to the cornua exposing the permanent contraception insert while avoiding direct electrosurgical application to the insert. The inserts were then removed intact with gentle traction. All 8 women underwent laparoscopic removal with salpingectomy. One patient had a surgical complication of serosal bowel injury due to laparoscopic entry that was repaired in the usual fashion. Operative time averaged 65 minutes (range, 30 to 100 minutes), blood loss was minimal, and there were no implant fractures.

Laparoscopic salpingectomy with insert transection

In this case series, Lazorwitz and Tocce described the use of laparoscopic salpingectomy for hysteroscopic permanent contraception insert removal in 20 women between 2011 and 2017. The authors described their surgical technique, which included division of the mesosalpinx followed by transection of the fallopian tube about 0.5 to 1 cm distal to the cornua. This process often resulted in transection of the insert, and the remaining insert was grasped and removed with gentle traction. If removal of the insert was incomplete, hysteroscopy was performed to identify remaining parts.

Indications for removal included pelvic pain (n = 14), abnormal uterine bleeding (n = 2), rash (n = 1), and unsuccessful placement or evidence of tubal occlusion failure during confirmatory imaging (n = 6). Three women underwent additional diagnostic hysteroscopy for retained implant fragments after laparoscopic salpingectomy. Fragments in all 3 women were 1 to 3 mm in size and left in situ as they were unable to be removed or located hysteroscopically. There were no reported postoperative complications including injury, infection, or readmission within 30 days of salpingectomy.

Shift in method use

Hysteroscopic permanent contraception procedures have low immediate surgical and medical complication rates but result in a high rate of reoperation to achieve the desired outcome.  Notably, the largest available comparative trials are from Europe, which may affect the generalizability to US providers, patients, and health care systems.

Importantly, since the introduction of hysteroscopic permanent contraception in 2002, the landscape of contraception has changed in the United States. Contraception use has shifted to fewer permanent procedures and more high-efficacy reversible options. Overall, reliance on female permanent contraception has been declining in the United States, accounting for 17.8% of contracepting women in 1995 and 15.5% in 2013.27,28 Permanent contraception has begun shifting from tubal interruption to salpingectomy as mounting evidence has demonstrated up to a 65% reduction in a woman's lifetime risk of ovarian cancer.29-32 A recent study from a large Northern California integrated health system reported an increase in salpingectomy for permanent contraception from 1% of interval procedures in 2011 to 78% in 2016.33

Long-acting reversible contraceptive (LARC) methods are also becoming more prevalent and are used by 7.2% of women using contraception in the United States.28,34 Typical use pregnancy rates with the levonorgestrel 52-mg intrauterine system, etonogestrel implant, and copper T380A intrauterine device are 0.2%, 0.2%, and 0.4% in the first year, respectively.35,37 These rates are about the same as those reported for Essure in the articles presented here.13,26 Because these methods are easily placed in the office and are immediately effective, their increased availability over the past decade changes demand for a permanent contraceptive procedure.

Essure underwent expedited FDA review because it had the potential to fill a contraceptive void--it was considered permanent, highly efficacious, low risk, and accessible to women regardless of health comorbidities or access to hospital operating rooms. The removal of Essure from the market is not only the result of a collection of problem reports (relatively small given the overall number of women who have used the device) but also the aggregate result of a changing marketplace and the differential needs of pharmaceutical companies and patients.

For a hysteroscopic permanent contraception insert to survive as a marketed product, the company needs high volume use. However, the increase in LARC provision and permanent contraceptive procedures using opportunistic salpingectomy have matured the market away from the presently available hysteroscopic method. This technology, in its current form, is ideal for women desiring permanent contraception but who have a contraindication to laparoscopic surgery, or for women who can access an office procedure in their community but lack access to a hospital-based procedure. For a pharmaceutical company, that smaller market may not be enough. However, the technology itself is still vital, and future development should focus on what we have learned; the ideal product should be immediately effective, not require a follow-up confirmation test, and not leave permanent foreign body within the uterus or tube.

WHAT THIS EVIDENCE MEANS FOR PRACTICE
Although both case series were small in sample size, they demonstrated the feasibility of laparoscopic removal of hysteroscopic permanent contraceptive implants. These papers described techniques that can likely be performed by individuals with appropriate laparoscopic skill and experience. The indication for most removals in these reports was pain, unsuccessful placement, or the inability to confirm tubal occlusion by imaging. Importantly, most women do not have these issues, and for those who have been using it successfully, removal is not indicated.

Female permanent contraception is among the most widely used contraceptive methods worldwide. In the United States, more than 640,000 procedures are performed each year and it is used by 25% of women who use contraception.1–4 Female permanent contraception is achieved via salpingectomy, tubal interruption, or hysteroscopic techniques.

Essure, the only currently available hysteroscopic permanent contraception device, approved by the US Food and Drug Administration (FDA) in 2002,5,6 has been implanted in more than 750,000 women worldwide.7 Essure was developed by Conceptus Inc, a small medical device company that was acquired by Bayer in 2013. The greatest uptake has been in the United States, which accounts for approximately 80% of procedures worldwide.7,8

Essure placement involves insertion of a nickel-titanium alloy coil with a stainless-steel inner coil, polyethylene terephthalate fibers, platinum marker bands, and silver-tin solder.9 The insert is approximately 4 cm in length and expands to 2 mm in diameter once deployed.9

Potential advantages of a hysteroscopic approach are that intra-abdominal surgery can be avoided and the procedure can be performed in an office without the need for general anesthesia.7 Due to these potential benefits, hysteroscopic permanent contraception with Essure underwent expedited review and received FDA approval without any comparative trials.1,5,10 However, there also are disadvantages: the method is not always successfully placed on first attempt and it is not immediately effective. Successful placement rates range between 60% and 98%, most commonly around 90%.11–15 Additionally, if placement is successful, alternative contraception must be used until a confirmatory radiologic test is performed at least 3 months after the procedure.9,11 Initially, hysterosalpingography was required to demonstrate a satisfactory insert location and successful tubal occlusion.11,16 Compliance with this testing is variable, ranging in studies from 13% to 71%.11 As of 2015, transvaginal ultrasonography showing insert retention and location has been approved as an alternative confirmatory method.9,11,16,17 Evidence suggests that the less invasive ultrasound option increases follow-up rates; while limited, one study noted an increase in follow-up rates from 77.5% for hysterosalpingogram to 88% (P = .008) for transvaginal ultrasound.18

Recent concerns about potential medical and safety issues have impacted approval status and marketing of hysteroscopic permanent contraception worldwide. In response to safety concerns, the FDA added a boxed safety warning and patient decision checklist in 2016.19 Bayer withdrew the device from all markets outside of the United States as of May 2017.20–22 In April 2018, the FDA restricted Essure sales in the United States only to providers and facilities who utilized an FDA-approved checklist to ensure the device met standards for safety and effectiveness.19 Most recently, Bayer announced that Essure would no longer be sold or distributed in the United States after December 31, 2018 (See “FDA Press Release”).23

FDA press release (July 20, 2018)
"The US Food and Drug Administration was notified by Bayer that the Essure permanent birth control device will no longer be sold or distributed after December 31, 2018... The decision today to halt Essure sales also follows a series of earlier actions that the FDA took to address the reports of serious adverse events associated with its use. For women who have received an Essure implant, the postmarket safety of Essure will continue to be a top priority for the FDA. We expect Bayer to meet its postmarket obligations concerning this device."

So how did we get here? How did the promise of a “less invasive” approach for female permanent contraception get off course?

A search of the Manufacturer and User Facility Device Experience (MAUDE) database from Essure’s approval date in 2002 to December 2017 revealed 26,773 medical device reports, with more than 90% of those received in 2017 related to device removal.19 As more complications and complaints have been reported, the lack of comparative data has presented a problem for understanding the relative risk of the procedure as compared with laparoscopic techniques. Additionally, the approval studies lacked information about what happened to women who had an unsuccessful attempted hysteroscopic procedure. Without robust data sets or large trials, early research used evidence-based Markov modeling; findings suggested that hysteroscopic permanent contraception resulted in fewer women achieving successful permanent contraception and that the hysteroscopic procedure was not as effective as laparoscopic occlusion procedures with “typical” use.24,25

Over the past year, more clinical data have been published comparing hysteroscopic with laparoscopic permanent contraception procedures. In this article, we evaluate this information to help us better understand the relative efficacy and safety of the different permanent contraception methods and review recent articles describing removal techniques to further assist clinicians and patients considering such procedures.

In this section, we present 3 recent studies that evaluate pregnancy outcomes and complications including reoperation or second permanent contraception procedure rates.

Data from France measure up to 3-year differences in adverse outcomes

Bouillon and colleagues aimed to identify differences in adverse outcome rates between hysteroscopic and laparoscopic permanent contraceptive methods. Utilizing national hospital discharge data in France, the researchers conducted a large database study review of records from more than 105,000 women aged 30 to 54 years receiving hysteroscopic or laparoscopic permanent contraception between 2010 and 2014. The database contains details based on the ICD-10 codes for all public and private hospitals in France, representing approximately 75% of the total population. Procedures were performed at 831 hospitals in 26 regions.

Adverse outcomes were divided into surgical, medical, and gynecologic complications (TABLE 1) and were assessed at 3 timepoints: at the time of procedure and at 1 and 3 years postprocedure.

Overall, 71,303 women (67.7%) underwent hysteroscopic permanent contraception procedures and 34,054 women (32.3%) underwent laparoscopic permanent contraception procedures. Immediate surgical and medical complications were significantly less common for women having hysteroscopic compared with laparoscopic procedures. Surgical complications at the time of the procedure occurred in 96 (0.13%) and 265 (0.78%) women, respectively (adjusted odds ratio [aOR], 0.18; 95% confidence interval [CI], 0.14-0.23). Medical complications at the time of procedure occurred in 41 (0.06%) and 39 (0.11%) women, respectively (aOR, 0.51; 95% CI, 0.30-0.89).

However, gynecologic outcomes, including need for a second surgery to provide permanent contraception and overall failure rates (need for salpingectomy, a second permanent contraception procedure, or pregnancy) were significantly more common for women having hysteroscopic procedures. By 1 year after the procedure, 2,955 women (4.10%) who initially had a hysteroscopic procedure, and 56 women (0.16%) who had a laparoscopic procedure required a second permanent contraception surgery (adjusted hazard ratio [aHR], 25.99; 95% CI, 17.84-37.86). By the third year, additional procedures were performed in 3,230 (4.5%) and 97 (0.28%) women, respectively (aHR, 16.63; 95% CI, 12.50-22.20). Most (65%) of the repeat procedures were performed laparoscopically. Although pregnancy rates were significantly lower at 1 year among women who initially chose a hysteroscopic procedure (0.24% vs 0.41%; aHR, 0.70; 95% CI, 0.53-0.92), the rates did not differ at 3 years (0.48% vs 0.57%, respectively; aHR, 1.04; 95% CI, 0.83-1.30).

Most importantly, overall procedure failure rates were significantly higher at 1 year in women initially choosing a hysteroscopic approach compared with laparoscopic approach (3,446 [4.83%] vs 235 [0.69%] women; aHR, 7.11; 95% CI, 5.92-8.54). This difference persisted through 3 years (4,098 [5.75%] vs 438 [1.29%] women, respectively; aHR, 4.66; 95% CI, 4.06-5.34).

UK data indicate high reoperation rate for hysteroscopic procedures

Antoun and colleagues aimed to compare pregnancy rates, radiologic imaging follow-up rates, reoperations, and 30-day adverse outcomes, between hysteroscopic and laparoscopic permanent contraception methods. Conducted at a single teaching hospital in the United Kingdom, this study included 3,497 women who underwent procedures between 2005 and 2015. The data were collected prospectively for the 1,085 women who underwent hysteroscopic procedures and retrospectively for 2,412 women who had laparoscopic permanent contraception procedures with the Filshie clip.

Over the 10-year study period, hysteroscopic permanent contraception increased from 14.2% (40 of 280) of procedures in 2005 to 40.5% (150 of 350) of procedures in 2015 (P<.001). Overall, 2,400 women (99.5%) underwent successful laparoscopic permanent contraception, compared with 992 women (91.4%) in the hysteroscopic group (OR, 18.8; 95% CI, 10.2-34.4).

In the hysteroscopic group, 958 women (97%) returned for confirmatory testing, of whom 902 (91% of women with successful placement) underwent satisfactory confirmatory testing. There were 93 (8.6%) unsuccessful placements that were due to inability to visualize ostia or tubal stenosis (n = 72 [77.4%]), patient intolerance to procedure (n = 15 [16.1%]), or device failure (n = 6 [6.5%]).

The odds for reoperation were 6 times greater in the hysteroscopic group by 1 year after surgery (22 [2%] vs 8 [0.3%] women; OR, 6.2; 95% CI, 2.8-14.0). However, the 1-year pregnancy risk was similar between the 2 groups, with 3 reported pregnancies after hysteroscopic permanent contraception and 5 reported pregnancies after laparoscopic permanent contraception (OR, 1.3; 95% CI, 0.3-5.6).

Finnish researchers also find high reoperation rate

Jokinen and colleagues used linked national database registries in Finland to capture data on pregnancy rate and reoperations among 16,272 women who underwent permanent contraception procedures between 2009 and 2014. The authors compared outcomes following hysteroscopic (Essure), laparoscopic (Filshie clip), and postpartum minilaparotomy (Pomeroy) permanent contraception techniques. According to the investigators, the latter method was almost exclusively performed at the time of cesarean delivery. While there was no difference in pregnancy rates, second permanent contraception procedures were significantly greater in the hysteroscopic group compared with the laparoscopic group (TABLE 2).

WHAT THIS EVIDENCE MEANS FOR PRACTICE
At a glance, these studies suggest that pregnancy rates are similar between hysteroscopic and laparoscopic permanent contraceptive approaches. But, these low failure rates were only achieved after including women who required reoperation or a second permanent contraceptive procedure. All 3 European studies showed a high follow-up rate; as method failure was identified, additional procedures were offered and performed when desired. These rates are higher than typically reported in US studies. None of the studies included discussion about the proportion of women with failed procedures who declined a second permanent contraceptive surgery. Bouillon et al26 reported a slight improvement in perioperative safety for a hysteroscopic procedure compared with a laparoscopic procedure. While severity of complications was not reported, the risk of reoperation for laparoscopic procedures remained <1%. By contrast, based on the evidence presented here, hysteroscopic permanent contraceptive methods required a second procedure for 4% to 8% of women, most of whom underwent a laparoscopic procedure. Thus, the slight potential improvement in safety of hysteroscopic procedures does not offset the significantly lower efficacy of the method.
 

 

Technique for hysteroscopic permanent contraception insert removal

Johal T, Kuruba N, Sule M, et al. Laparoscopic salpingectomy and removal of Essure hysteroscopic sterilisation device: a case series. Eur J Contracept Reprod Health Care. 2018;23(3):227-230.

As reports of complications and concerns with hysteroscopic permanent contraception increase, there has been a rise in device removal procedures. We present 2 recent articles that review laparoscopic techniques for the removal of hysteroscopic permanent contraception devices and describe subsequent outcomes.

Laparoscopic salpingectomy without insert transection

In this descriptive retrospective study, Johal and colleagues reviewed hysteroscopic permanent contraception insert removal in 8 women between 2015 and 2017. The authors described their laparoscopic salpingectomy approach and perioperative complications. Overall safety and feasibility with laparoscopic salpingectomy were evaluated by identifying the number of procedures requiring intraoperative conversion to laparotomy, cornuectomy, or hysterectomy. The authors also measured operative time, estimated blood loss, length of stay, and incidence of implant fracture.

Indications for insert removal included pain (n = 4), dyspareunia (n = 2), abnormal uterine bleeding (n = 1), and unsuccessful placement or evidence of tubal occlusion failure during confirmatory imaging (n = 4). The surgeons divided the mesosalpinx and then transected the fallopian tube approximately 1 cm distal to the cornua exposing the permanent contraception insert while avoiding direct electrosurgical application to the insert. The inserts were then removed intact with gentle traction. All 8 women underwent laparoscopic removal with salpingectomy. One patient had a surgical complication of serosal bowel injury due to laparoscopic entry that was repaired in the usual fashion. Operative time averaged 65 minutes (range, 30 to 100 minutes), blood loss was minimal, and there were no implant fractures.

Laparoscopic salpingectomy with insert transection

In this case series, Lazorwitz and Tocce described the use of laparoscopic salpingectomy for hysteroscopic permanent contraception insert removal in 20 women between 2011 and 2017. The authors described their surgical technique, which included division of the mesosalpinx followed by transection of the fallopian tube about 0.5 to 1 cm distal to the cornua. This process often resulted in transection of the insert, and the remaining insert was grasped and removed with gentle traction. If removal of the insert was incomplete, hysteroscopy was performed to identify remaining parts.

Indications for removal included pelvic pain (n = 14), abnormal uterine bleeding (n = 2), rash (n = 1), and unsuccessful placement or evidence of tubal occlusion failure during confirmatory imaging (n = 6). Three women underwent additional diagnostic hysteroscopy for retained implant fragments after laparoscopic salpingectomy. Fragments in all 3 women were 1 to 3 mm in size and left in situ as they were unable to be removed or located hysteroscopically. There were no reported postoperative complications including injury, infection, or readmission within 30 days of salpingectomy.

Shift in method use

Hysteroscopic permanent contraception procedures have low immediate surgical and medical complication rates but result in a high rate of reoperation to achieve the desired outcome.  Notably, the largest available comparative trials are from Europe, which may affect the generalizability to US providers, patients, and health care systems.

Importantly, since the introduction of hysteroscopic permanent contraception in 2002, the landscape of contraception has changed in the United States. Contraception use has shifted to fewer permanent procedures and more high-efficacy reversible options. Overall, reliance on female permanent contraception has been declining in the United States, accounting for 17.8% of contracepting women in 1995 and 15.5% in 2013.27,28 Permanent contraception has begun shifting from tubal interruption to salpingectomy as mounting evidence has demonstrated up to a 65% reduction in a woman's lifetime risk of ovarian cancer.29-32 A recent study from a large Northern California integrated health system reported an increase in salpingectomy for permanent contraception from 1% of interval procedures in 2011 to 78% in 2016.33

Long-acting reversible contraceptive (LARC) methods are also becoming more prevalent and are used by 7.2% of women using contraception in the United States.28,34 Typical use pregnancy rates with the levonorgestrel 52-mg intrauterine system, etonogestrel implant, and copper T380A intrauterine device are 0.2%, 0.2%, and 0.4% in the first year, respectively.35,37 These rates are about the same as those reported for Essure in the articles presented here.13,26 Because these methods are easily placed in the office and are immediately effective, their increased availability over the past decade changes demand for a permanent contraceptive procedure.

Essure underwent expedited FDA review because it had the potential to fill a contraceptive void--it was considered permanent, highly efficacious, low risk, and accessible to women regardless of health comorbidities or access to hospital operating rooms. The removal of Essure from the market is not only the result of a collection of problem reports (relatively small given the overall number of women who have used the device) but also the aggregate result of a changing marketplace and the differential needs of pharmaceutical companies and patients.

For a hysteroscopic permanent contraception insert to survive as a marketed product, the company needs high volume use. However, the increase in LARC provision and permanent contraceptive procedures using opportunistic salpingectomy have matured the market away from the presently available hysteroscopic method. This technology, in its current form, is ideal for women desiring permanent contraception but who have a contraindication to laparoscopic surgery, or for women who can access an office procedure in their community but lack access to a hospital-based procedure. For a pharmaceutical company, that smaller market may not be enough. However, the technology itself is still vital, and future development should focus on what we have learned; the ideal product should be immediately effective, not require a follow-up confirmation test, and not leave permanent foreign body within the uterus or tube.

WHAT THIS EVIDENCE MEANS FOR PRACTICE
Although both case series were small in sample size, they demonstrated the feasibility of laparoscopic removal of hysteroscopic permanent contraceptive implants. These papers described techniques that can likely be performed by individuals with appropriate laparoscopic skill and experience. The indication for most removals in these reports was pain, unsuccessful placement, or the inability to confirm tubal occlusion by imaging. Importantly, most women do not have these issues, and for those who have been using it successfully, removal is not indicated.

Female permanent contraception is among the most widely used contraceptive methods worldwide. In the United States, more than 640,000 procedures are performed each year and it is used by 25% of women who use contraception.1–4 Female permanent contraception is achieved via salpingectomy, tubal interruption, or hysteroscopic techniques.

Essure, the only currently available hysteroscopic permanent contraception device, approved by the US Food and Drug Administration (FDA) in 2002,5,6 has been implanted in more than 750,000 women worldwide.7 Essure was developed by Conceptus Inc, a small medical device company that was acquired by Bayer in 2013. The greatest uptake has been in the United States, which accounts for approximately 80% of procedures worldwide.7,8

Essure placement involves insertion of a nickel-titanium alloy coil with a stainless-steel inner coil, polyethylene terephthalate fibers, platinum marker bands, and silver-tin solder.9 The insert is approximately 4 cm in length and expands to 2 mm in diameter once deployed.9

Potential advantages of a hysteroscopic approach are that intra-abdominal surgery can be avoided and the procedure can be performed in an office without the need for general anesthesia.7 Due to these potential benefits, hysteroscopic permanent contraception with Essure underwent expedited review and received FDA approval without any comparative trials.1,5,10 However, there also are disadvantages: the method is not always successfully placed on first attempt and it is not immediately effective. Successful placement rates range between 60% and 98%, most commonly around 90%.11–15 Additionally, if placement is successful, alternative contraception must be used until a confirmatory radiologic test is performed at least 3 months after the procedure.9,11 Initially, hysterosalpingography was required to demonstrate a satisfactory insert location and successful tubal occlusion.11,16 Compliance with this testing is variable, ranging in studies from 13% to 71%.11 As of 2015, transvaginal ultrasonography showing insert retention and location has been approved as an alternative confirmatory method.9,11,16,17 Evidence suggests that the less invasive ultrasound option increases follow-up rates; while limited, one study noted an increase in follow-up rates from 77.5% for hysterosalpingogram to 88% (P = .008) for transvaginal ultrasound.18

Recent concerns about potential medical and safety issues have impacted approval status and marketing of hysteroscopic permanent contraception worldwide. In response to safety concerns, the FDA added a boxed safety warning and patient decision checklist in 2016.19 Bayer withdrew the device from all markets outside of the United States as of May 2017.20–22 In April 2018, the FDA restricted Essure sales in the United States only to providers and facilities who utilized an FDA-approved checklist to ensure the device met standards for safety and effectiveness.19 Most recently, Bayer announced that Essure would no longer be sold or distributed in the United States after December 31, 2018 (See “FDA Press Release”).23

FDA press release (July 20, 2018)
"The US Food and Drug Administration was notified by Bayer that the Essure permanent birth control device will no longer be sold or distributed after December 31, 2018... The decision today to halt Essure sales also follows a series of earlier actions that the FDA took to address the reports of serious adverse events associated with its use. For women who have received an Essure implant, the postmarket safety of Essure will continue to be a top priority for the FDA. We expect Bayer to meet its postmarket obligations concerning this device."

So how did we get here? How did the promise of a “less invasive” approach for female permanent contraception get off course?

A search of the Manufacturer and User Facility Device Experience (MAUDE) database from Essure’s approval date in 2002 to December 2017 revealed 26,773 medical device reports, with more than 90% of those received in 2017 related to device removal.19 As more complications and complaints have been reported, the lack of comparative data has presented a problem for understanding the relative risk of the procedure as compared with laparoscopic techniques. Additionally, the approval studies lacked information about what happened to women who had an unsuccessful attempted hysteroscopic procedure. Without robust data sets or large trials, early research used evidence-based Markov modeling; findings suggested that hysteroscopic permanent contraception resulted in fewer women achieving successful permanent contraception and that the hysteroscopic procedure was not as effective as laparoscopic occlusion procedures with “typical” use.24,25

Over the past year, more clinical data have been published comparing hysteroscopic with laparoscopic permanent contraception procedures. In this article, we evaluate this information to help us better understand the relative efficacy and safety of the different permanent contraception methods and review recent articles describing removal techniques to further assist clinicians and patients considering such procedures.

In this section, we present 3 recent studies that evaluate pregnancy outcomes and complications including reoperation or second permanent contraception procedure rates.

Data from France measure up to 3-year differences in adverse outcomes

Bouillon and colleagues aimed to identify differences in adverse outcome rates between hysteroscopic and laparoscopic permanent contraceptive methods. Utilizing national hospital discharge data in France, the researchers conducted a large database study review of records from more than 105,000 women aged 30 to 54 years receiving hysteroscopic or laparoscopic permanent contraception between 2010 and 2014. The database contains details based on the ICD-10 codes for all public and private hospitals in France, representing approximately 75% of the total population. Procedures were performed at 831 hospitals in 26 regions.

Adverse outcomes were divided into surgical, medical, and gynecologic complications (TABLE 1) and were assessed at 3 timepoints: at the time of procedure and at 1 and 3 years postprocedure.

Overall, 71,303 women (67.7%) underwent hysteroscopic permanent contraception procedures and 34,054 women (32.3%) underwent laparoscopic permanent contraception procedures. Immediate surgical and medical complications were significantly less common for women having hysteroscopic compared with laparoscopic procedures. Surgical complications at the time of the procedure occurred in 96 (0.13%) and 265 (0.78%) women, respectively (adjusted odds ratio [aOR], 0.18; 95% confidence interval [CI], 0.14-0.23). Medical complications at the time of procedure occurred in 41 (0.06%) and 39 (0.11%) women, respectively (aOR, 0.51; 95% CI, 0.30-0.89).

However, gynecologic outcomes, including need for a second surgery to provide permanent contraception and overall failure rates (need for salpingectomy, a second permanent contraception procedure, or pregnancy) were significantly more common for women having hysteroscopic procedures. By 1 year after the procedure, 2,955 women (4.10%) who initially had a hysteroscopic procedure, and 56 women (0.16%) who had a laparoscopic procedure required a second permanent contraception surgery (adjusted hazard ratio [aHR], 25.99; 95% CI, 17.84-37.86). By the third year, additional procedures were performed in 3,230 (4.5%) and 97 (0.28%) women, respectively (aHR, 16.63; 95% CI, 12.50-22.20). Most (65%) of the repeat procedures were performed laparoscopically. Although pregnancy rates were significantly lower at 1 year among women who initially chose a hysteroscopic procedure (0.24% vs 0.41%; aHR, 0.70; 95% CI, 0.53-0.92), the rates did not differ at 3 years (0.48% vs 0.57%, respectively; aHR, 1.04; 95% CI, 0.83-1.30).

Most importantly, overall procedure failure rates were significantly higher at 1 year in women initially choosing a hysteroscopic approach compared with laparoscopic approach (3,446 [4.83%] vs 235 [0.69%] women; aHR, 7.11; 95% CI, 5.92-8.54). This difference persisted through 3 years (4,098 [5.75%] vs 438 [1.29%] women, respectively; aHR, 4.66; 95% CI, 4.06-5.34).

UK data indicate high reoperation rate for hysteroscopic procedures

Antoun and colleagues aimed to compare pregnancy rates, radiologic imaging follow-up rates, reoperations, and 30-day adverse outcomes, between hysteroscopic and laparoscopic permanent contraception methods. Conducted at a single teaching hospital in the United Kingdom, this study included 3,497 women who underwent procedures between 2005 and 2015. The data were collected prospectively for the 1,085 women who underwent hysteroscopic procedures and retrospectively for 2,412 women who had laparoscopic permanent contraception procedures with the Filshie clip.

Over the 10-year study period, hysteroscopic permanent contraception increased from 14.2% (40 of 280) of procedures in 2005 to 40.5% (150 of 350) of procedures in 2015 (P<.001). Overall, 2,400 women (99.5%) underwent successful laparoscopic permanent contraception, compared with 992 women (91.4%) in the hysteroscopic group (OR, 18.8; 95% CI, 10.2-34.4).

In the hysteroscopic group, 958 women (97%) returned for confirmatory testing, of whom 902 (91% of women with successful placement) underwent satisfactory confirmatory testing. There were 93 (8.6%) unsuccessful placements that were due to inability to visualize ostia or tubal stenosis (n = 72 [77.4%]), patient intolerance to procedure (n = 15 [16.1%]), or device failure (n = 6 [6.5%]).

The odds for reoperation were 6 times greater in the hysteroscopic group by 1 year after surgery (22 [2%] vs 8 [0.3%] women; OR, 6.2; 95% CI, 2.8-14.0). However, the 1-year pregnancy risk was similar between the 2 groups, with 3 reported pregnancies after hysteroscopic permanent contraception and 5 reported pregnancies after laparoscopic permanent contraception (OR, 1.3; 95% CI, 0.3-5.6).

Finnish researchers also find high reoperation rate

Jokinen and colleagues used linked national database registries in Finland to capture data on pregnancy rate and reoperations among 16,272 women who underwent permanent contraception procedures between 2009 and 2014. The authors compared outcomes following hysteroscopic (Essure), laparoscopic (Filshie clip), and postpartum minilaparotomy (Pomeroy) permanent contraception techniques. According to the investigators, the latter method was almost exclusively performed at the time of cesarean delivery. While there was no difference in pregnancy rates, second permanent contraception procedures were significantly greater in the hysteroscopic group compared with the laparoscopic group (TABLE 2).

WHAT THIS EVIDENCE MEANS FOR PRACTICE
At a glance, these studies suggest that pregnancy rates are similar between hysteroscopic and laparoscopic permanent contraceptive approaches. But, these low failure rates were only achieved after including women who required reoperation or a second permanent contraceptive procedure. All 3 European studies showed a high follow-up rate; as method failure was identified, additional procedures were offered and performed when desired. These rates are higher than typically reported in US studies. None of the studies included discussion about the proportion of women with failed procedures who declined a second permanent contraceptive surgery. Bouillon et al26 reported a slight improvement in perioperative safety for a hysteroscopic procedure compared with a laparoscopic procedure. While severity of complications was not reported, the risk of reoperation for laparoscopic procedures remained <1%. By contrast, based on the evidence presented here, hysteroscopic permanent contraceptive methods required a second procedure for 4% to 8% of women, most of whom underwent a laparoscopic procedure. Thus, the slight potential improvement in safety of hysteroscopic procedures does not offset the significantly lower efficacy of the method.

As reports of complications and concerns with hysteroscopic permanent contraception increase, there has been a rise in device removal procedures. We present 2 recent articles that review laparoscopic techniques for the removal of hysteroscopic permanent contraception devices and describe subsequent outcomes.

Laparoscopic salpingectomy without insert transection

In this descriptive retrospective study, Johal and colleagues reviewed hysteroscopic permanent contraception insert removal in 8 women between 2015 and 2017. The authors described their laparoscopic salpingectomy approach and perioperative complications. Overall safety and feasibility with laparoscopic salpingectomy were evaluated by identifying the number of procedures requiring intraoperative conversion to laparotomy, cornuectomy, or hysterectomy. The authors also measured operative time, estimated blood loss, length of stay, and incidence of implant fracture.

Indications for insert removal included pain (n = 4), dyspareunia (n = 2), abnormal uterine bleeding (n = 1), and unsuccessful placement or evidence of tubal occlusion failure during confirmatory imaging (n = 4). The surgeons divided the mesosalpinx and then transected the fallopian tube approximately 1 cm distal to the cornua exposing the permanent contraception insert while avoiding direct electrosurgical application to the insert. The inserts were then removed intact with gentle traction. All 8 women underwent laparoscopic removal with salpingectomy. One patient had a surgical complication of serosal bowel injury due to laparoscopic entry that was repaired in the usual fashion. Operative time averaged 65 minutes (range, 30 to 100 minutes), blood loss was minimal, and there were no implant fractures.

Laparoscopic salpingectomy with insert transection

In this case series, Lazorwitz and Tocce described the use of laparoscopic salpingectomy for hysteroscopic permanent contraception insert removal in 20 women between 2011 and 2017. The authors described their surgical technique, which included division of the mesosalpinx followed by transection of the fallopian tube about 0.5 to 1 cm distal to the cornua. This process often resulted in transection of the insert, and the remaining insert was grasped and removed with gentle traction. If removal of the insert was incomplete, hysteroscopy was performed to identify remaining parts.

Indications for removal included pelvic pain (n = 14), abnormal uterine bleeding (n = 2), rash (n = 1), and unsuccessful placement or evidence of tubal occlusion failure during confirmatory imaging (n = 6). Three women underwent additional diagnostic hysteroscopy for retained implant fragments after laparoscopic salpingectomy. Fragments in all 3 women were 1 to 3 mm in size and left in situ as they were unable to be removed or located hysteroscopically. There were no reported postoperative complications including injury, infection, or readmission within 30 days of salpingectomy.

Shift in method use

Hysteroscopic permanent contraception procedures have low immediate surgical and medical complication rates but result in a high rate of reoperation to achieve the desired outcome.  Notably, the largest available comparative trials are from Europe, which may affect the generalizability to US providers, patients, and health care systems.

Importantly, since the introduction of hysteroscopic permanent contraception in 2002, the landscape of contraception has changed in the United States. Contraception use has shifted to fewer permanent procedures and more high-efficacy reversible options. Overall, reliance on female permanent contraception has been declining in the United States, accounting for 17.8% of contracepting women in 1995 and 15.5% in 2013.27,28 Permanent contraception has begun shifting from tubal interruption to salpingectomy as mounting evidence has demonstrated up to a 65% reduction in a woman's lifetime risk of ovarian cancer.29-32 A recent study from a large Northern California integrated health system reported an increase in salpingectomy for permanent contraception from 1% of interval procedures in 2011 to 78% in 2016.33

Long-acting reversible contraceptive (LARC) methods are also becoming more prevalent and are used by 7.2% of women using contraception in the United States.28,34 Typical use pregnancy rates with the levonorgestrel 52-mg intrauterine system, etonogestrel implant, and copper T380A intrauterine device are 0.2%, 0.2%, and 0.4% in the first year, respectively.35,37 These rates are about the same as those reported for Essure in the articles presented here.13,26 Because these methods are easily placed in the office and are immediately effective, their increased availability over the past decade changes demand for a permanent contraceptive procedure.

Essure underwent expedited FDA review because it had the potential to fill a contraceptive void--it was considered permanent, highly efficacious, low risk, and accessible to women regardless of health comorbidities or access to hospital operating rooms. The removal of Essure from the market is not only the result of a collection of problem reports (relatively small given the overall number of women who have used the device) but also the aggregate result of a changing marketplace and the differential needs of pharmaceutical companies and patients.

For a hysteroscopic permanent contraception insert to survive as a marketed product, the company needs high volume use. However, the increase in LARC provision and permanent contraceptive procedures using opportunistic salpingectomy have matured the market away from the presently available hysteroscopic method. This technology, in its current form, is ideal for women desiring permanent contraception but who have a contraindication to laparoscopic surgery, or for women who can access an office procedure in their community but lack access to a hospital-based procedure. For a pharmaceutical company, that smaller market may not be enough. However, the technology itself is still vital, and future development should focus on what we have learned; the ideal product should be immediately effective, not require a follow-up confirmation test, and not leave permanent foreign body within the uterus or tube.

WHAT THIS EVIDENCE MEANS FOR PRACTICE
Although both case series were small in sample size, they demonstrated the feasibility of laparoscopic removal of hysteroscopic permanent contraceptive implants. These papers described techniques that can likely be performed by individuals with appropriate laparoscopic skill and experience. The indication for most removals in these reports was pain, unsuccessful placement, or the inability to confirm tubal occlusion by imaging. Importantly, most women do not have these issues, and for those who have been using it successfully, removal is not indicated.
