Essure: Hysteroscopic Sterilization

Salpingectomy, tubal ligation and hysteroscopic occlusion for sterilization

INTRODUCTION

Sterilization of females is considered one of the most prevalent contraceptive techniques among women in the United States. There are many surgical sterilization procedures including salpingectomy, tubal ligation, and hysteroscopic occlusion of the fallopian tubes. We provide an overview of these methods from the clinical data and latest studies available on this topic.

EVIDENCE ACQUISITION

In order to review the latest literature on the topic, we searched electronic databases including PubMed, Web of Science, Scopus, and Cochrane library for all eligible studies from May 1st 2018 until May 1st 2022 using the following strategy: ("fallopian tube removal" OR Salpingectomy OR "fallopian tube excision" OR "tubal sterilization") AND ("tubal ligation" OR "bipolar coagulation" OR "tubal clip" OR "tubal ring" OR fimbriectomy). We reviewed every study that met our criteria and subjectively considered their results and methodology into this narrative review.

EVIDENCE SYNTHESIS

In addition to reviewing major guidelines in the United States, 19 recent studies met our eligibility criteria and were included in this review. We grouped the findings under the following headings: anatomical and physiological considerations, sterilization, salpingectomy, tubal ligation, and hysteroscopic tubal occlusion.

CONCLUSIONS

Bilateral salpingectomy and techniques of tubal ligation or occlusion continue to be effective procedures with good safety profiles. All techniques have similar surgical outcomes and long-term success rates. As salpingectomy has the advantage of reducing the risk of occurrence of ovarian cancer, this is preferential when feasible. Hysteroscopic occlusion techniques may be more minimally invasive but have the disadvantages of delayed efficacy, the need for a second invasive diagnostic procedure, and limited availability.

Hysteroscopic tubal occlusion using iso-amyl-2-cyanoacrylate in patients with hydrosalpinx

AIM

The aim of this work is to assess the effectiveness of hysteroscopic tubal occlusion using iso-amyl-2-cyanoacrylate, among infertile women with hydrosalpinx prior to in vitro fertilization (IVF).

METHODS

Hysteroscopic injection of fallopian tubes with hydrosalpinx by 0.5 mL iso-amyl-2-cyanoacrylate was done in 40 infertile women planning for IVF. The patients were then followed-up after 1 and 3 months, with hysterosalpingography (HSG) to confirm complete tubal occlusion. Reinjection with iso-amyl-2-cyanoacrylate was done in these patients with incomplete tubal occlusion after 1 month of the first injection, followed by HSG 2 months later to confirm complete tubal occlusion. Data were prescribed as range, mean and standard deviation (for parametric variables) and range, number and percentage (for categorical variables).

RESULTS

The total number of tubes injected in this study was 54, 42 (77.8%) of which were completely occluded after one injection while 12 (22.2%) were partially occluded. Reinjection of the partially occluded tubes was done, and (HSG) of all patients after 3 months of the primary injection confirmed 48 (88.9%) of the tubes completely occluded while 6 (11.1%) remained partially occluded. Thirty-two (80%) patients underwent one cycle of IVF/ET (embryo transfer), while 8 (20%) patients did not appear for follow-up. Among the patients who underwent IVF/ET, 24 (75%) got pregnant, while 8 (25%) failed to conceive. Among the pregnant patients, 8 (33.3%) delivered at term, 3 (12.5%) had first trimester abortion, while the remaining 13 (54.2%) did not deliver yet.

CONCLUSION

Iso-amyl-2-cyanoacrylate used for hysteroscopic tubal occlusion in patients with hydrosalpinx prior to IVF is safe and effective.

Contraception in women with cardiac disease

Cardiac disease is the main cause of maternal mortality in the UK; therefore, accurate and appropriate contraceptive advice for women with cardiac disease is an essential part of any consultation. All females should be counseled regarding pregnancy and contraception before they become sexually active, with information tailored to their diagnosis and risks of a pregnancy. In this review, we discuss current clinical recommendations and practice in a number of different cardiac conditions, including congenital heart disease, as well as highlighting future developments and challenges with contraception in women with cardiac disease.

Efficacy, safety, and patient acceptability of the Essure™ procedure

The Essure™ system for permanent contraception was developed as a less invasive method of female sterilization. Placement of the Essure™ coil involves a hysteroscopic transcervical technique. This procedure can be done in a variety of settings and with a range of anesthetic options. More than eight years have passed since the US Food and Drug Administration approval of Essure™. Much research has been done to evaluate placement success, adverse outcomes, satisfaction, pain, and the contraceptive efficacy of the Essure™. The purpose of this review is to summarize the available literature regarding the efficacy, safety, and patient satisfaction with this new sterilization technique.

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.

[Ambulatory Essure implant placement sterilization procedure for women: prospective study comparing general anesthesia versus hypnosis combined with sedation]

OBJECTIVE

implant placement Essure, sterilization procedure for women, were performed under hypnosedation (HYP) and compared to the operative anxiety and analgesia of 12 patients operated-on under general anesthesia (GA).

STUDY DESIGN

prospective and comparative group study.

PATIENTS AND METHODS

two groups of twelve patients were matched and compared based on the choice of anesthetic technique: hypnotics (HYP) with possible additional sedation by propofol and remifentanil or GA involving propofol, sevoflurane and remifentanil. The assessment of anxiety and pain based on a visual analogy scale (0-10) and use of analgesics were studied in the recovery room and at discharge of hospital. The statistical analysis relies on nonparametric tests for paired data (Wilcoxon test).

RESULTS

all patients were operated. The two groups are statistically comparable. The preoperative anxiety before premedication is lower in the HYP group (p<0.05). No conversion to general anaesthesia is necessary in the HYP group, but five patients were using sedatives drugs but doses are very low compared to general anaesthesia. The analgesic consumption was equivalent in both groups.

CONCLUSION

we conclude that hypnosedation is a valuable alternative to traditional anesthetic techniques for ambulatory Essure implant. The use of hypnotic tool is an interesting alternative for the management of patients during invasive medical procedures or surgical, providing psychological benefits to the patient.

Hysteroscopic sterilization with occlusion of sheep uterine tube using n-butyl-2-cyanoacrylate adhesive

PURPOSE: To evaluate the fertility and analyze the macroscopic, microscopic and morphometric aspects of sheep uterine tube sterilization with a hysteroscopically insert of n-butyl-2-cyanoacrylate adhesive. METHODS: 12 adult sheep, with one previous pregnancy, were distributed as follows: group L (n=3) subjected to laparotomy and Pomeroy uterine tube ligation, group S (n=3) subjected to hysteroscopic application of saline solution in tube isthmus and group AD(n=6), that was subjected to hysteroscopic application of 0.5 ml of n-2-butil-cyanoacrylate in tube isthmus. They were mated with fertile males for ninety days. The non pregnant sheep, at the 90th day, were subjected to laparotomy with uterus and tubes uterine resection. The fragments of uterine tubes were fixated in 10% formalin and processes for histology evaluated, and slices dyes for H.E. Data were evaluated by Wilcoxon and Mann-Whitney and Fisher's exact test. RESULTS: All sheep from groups L and AD did not get pregnant (0%) in contrast with sheep from group S (100%); the adhesive remained integral in the uterine tube lumen. The percentual of adherences (66.6%) and fibrosis responses (100%) was significantly higher in the group L than group AD (0%) (p<0.01). The diameter of the caudal tube in group AD (2652.15 ± 45.76 mm) was significantly wider than that of the group L (1868.27 ± 56.11* µm) (p < 0.05). CONCLUSION: The hysteroscopic insertion of cyanoacrylate in the uterine tube lumen of sheep was effective to obstruct the uterine tube and to promote the sterilization.
