Waste analysis and energy use estimation during MR-HIFU treatment: first steps towards calculating total environmental impact.

OBJECTIVES: To assess the environmental impact of the non-invasive Magnetic Resonance image-guided High-Intensity Focused Ultrasound (MR-HIFU) treatment of uterine fibroids, we aimed to perform a full Life Cycle Assessment (LCA). However, as a full LCA was not feasible at this time, we evaluated the CO2 (carbon dioxide) emission from the MRI scanner, MR-HIFU device, and the medication used, and analyzed solid waste produced during treatment. METHODS: Our functional unit was one uterine fibroid MR-HIFU treatment. The moment the patient entered the day care-unit until she left, defined our boundaries of investigation. We retrospectively collected data from 25 treatments to assess the CO2 emission based on the energy used by the MRI scanner and MR-HIFU device and the amount and type of medication administered. Solid waste was prospectively collected from five treatments. RESULTS: During an MR-HIFU treatment, the MRI scanner and MR-HIFU device produced 33.2 ± 8.7 kg of CO2 emission and medication administered 0.13 ± 0.04 kg. A uterine fibroid MR-HIFU treatment produced 1.2 kg (range 1.1-1.4) of solid waste. CONCLUSIONS: Environmental impact should ideally be analyzed for all (new) medical treatments. By assessing part of the CO2 emission and solid waste produced, we have taken the first steps towards analyzing the total environmental impact of the MR-HIFU treatment of uterine fibroids. These data can contribute to future studies comparing the results of MR-HIFU LCAs with LCAs of other uterine fibroid therapies. CRITICAL RELEVANCE STATEMENT: In addition to (cost-) effectiveness, the environmental impact of new treatments should be assessed. We took the first steps towards analyzing the total environmental impact of uterine fibroid MR-HIFU. KEY POINTS: • Life Cycle Assessments (LCAs) should be performed for all (new) medical treatments. • We took the first steps towards analyzing the environmental impact of uterine fibroid MR-HIFU. • Energy used by the MRI scanner and MR-HIFU device corresponded to 33.2 ± 8.7 kg of CO2 emission.

Laparoscopic Trocars: Marketed Versus True Dimensions-A Descriptive Study.

STUDY OBJECTIVE: To establish true dimensions of single-use laparoscopic trocars compared with marketed dimensions, calculate corresponding incision sizes, examine what trocar size categories are based on, and outline accessibility of information regarding true dimensions. DESIGN: Descriptive study. SETTING: Laparoscopic disposable trocars available in North America and Europe are marketed in several distinct categories. In practice, trocars in the same-size category exhibit different functionality (ability to introduce instruments/needles and retrieve specimens) and warrant different incision lengths. PATIENTS: Not applicable. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: True dimensions for 125 trocars (bladeless, optical, and balloon) were obtained from 9 vendors covering 8 marketed size categories (3-, 3.5-, 5-, 8-, 10-, 11-, 12-, and 15-mm trocars). On average, true inner cannula diameter was 0.92 mm wider (SD, 0.41 mm; range, 0-2.4 mm) than the marketed size category, with the widest range in the 5 mm category. For 5-mm trocars, mean true inner diameter was 6.1 mm (SD, 0.45; range, 5.5-7.4) and true outer diameter 8.3 mm (SD, 0.71; range, 8.0-10.7). For 12-mm trocars, mean true inner diameter was 13.0 mm (SD, 0.21; range, 12-13.3) and outer diameter 15.3 mm (SD, 0.48; range, 14.4-16.8). Five-mm trocars necessitate a mean incision size of 13.0 mm (SD, 1.1; range, 12.1-16.8) and 12-mm trocars a mean incision of 24.0 mm (SD, 0.75; range, 22.6-26.4). No vendors stated actual diameters on company website or catalog. In one instance the Instructions For Use document contained the true inner diameter. CONCLUSION: Trocar size categories give a false sense of standardization when in actuality there are considerable within-category differences in both inner and outer diameters, corresponding to differences in functionality and required incision sizes. There is no universally applied definition for trocar size categories. Accessibility of information on true dimensions is limited.

Hormonal support in women with Asherman syndrome does not lead to better outcomes: A randomized trial.

Purpose: The purpose of the study was to investigate if adjuvant hormones after successful adhesiolysis lead to a reduction in spontaneous recurrence of adhesions and influence reproductive outcomes. Methods: A single-blind randomized controlled trial comparing administration of oral estrogen (the usual care group) with not giving estrogen (no estrogen) in women after successful adhesiolysis for Asherman syndrome. Women were included between September 2013 and February 2017, with a follow-up of 3 years to monitor recurrences and reproductive outcomes. Analyses were based on an intention to treat analyses. This study was registered under NL9655. Results: A total of 114 women were included. At 1 year, virtually all patients (except 3) were either having a recurrence or were pregnant. Women who did not receive estrogen did not have more recurrences of adhesions in the first year prior to pregnancy (66.1% in the usual care group, 52.7% in the no-estrogen group, p = 0.15). Of the women in usual care, 89.8% got pregnant within 3 years, and 67.8% got a living child; this was 83.6% and 60.0%, respectively, in the no-estrogen group (p = 0.33 and p = 0.39, respectively). Conclusion: Usual care does not lead to better outcomes as compared with not giving exogenous estrogen but is associated with side effects.

Essure removal surgery: Are preoperative transvaginal ultrasound and pelvic X-ray necessary?

OBJECTIVE: The objective of this study was twofold. (1) To investigate the predictive characteristics of transvaginal ultrasonography for hysteroscopy necessity in Essure removal surgery. (2) To investigate the additional predictive value of a preoperative pelvic radiograph to transvaginal ultrasonography for hysteroscopy necessity. STUDY DESIGN: Retrospective cohort study, performed in an academic and a non-academic teaching hospital in the Netherlands. 71 women who underwent Essure removal surgery with a perioperative hysteroscopy and who had a preoperative pelvic X-ray and transvaginal ultrasound were included. Four experts first predicted hysteroscopy necessity based on transvaginal ultrasound description and secondly based on transvaginal ultrasound combined with the preoperative pelvic radiograph. Sensitivity, specificity, positive predictive value and negative predictive value of the predictive tests were calculated. RESULTS: Based on transvaginal ultrasound, the mean predictive characteristics for experts were: sensitivity 89.7% (range 66.7%-100%), specificity 37.4% (range 17.6%-67.7%), positive predictive value 18.8% (range 13.2%-29.5%) and negative predictive value 95.1% (range 86.1%-100%). After adding the pelvic radiograph to the transvaginal ultrasound descriptions, the results were: sensitivity 66.7% (range 53.3%-80%), specificity 72.6% (range 56%-97.3%), positive predictive value 23% (range 14.3%-26.9%) and negative predictive value 94.1 % (range 90.3%-98.4%). For three experts sensitivity decreased after adding the pelvic radiograph. For all experts specificity increased. CONCLUSION: It is difficult to preoperatively decide if the fourth marker of the Essure outer coil can be excised during hysteroscopy. The addition of pelvic radiography to transvaginal ultrasound is not beneficial. It is recommended to perform a hysteroscopy during Essure removal surgery.

Is 2-dimensional transvaginal ultrasonography necessary 6 weeks after insertion of the levonorgestrel 52-mg intrauterine device?

BACKGROUND: In Dutch practice, gynecologists are used to assessing the position of the LNG-IUD by performing a two-dimensional transvaginal ultrasonography (TVUS) directly after insertion and do not routinely invite patients for another consultation 4-12 weeks after insertion. There is no consensus whether a TVUS six weeks after insertion is routinely needed. OBJECTIVE: This study aimed to assess the incidence of malposition using 2-dimensional transvaginal ultrasonography during routine investigation 6 weeks after insertion. In addition, we investigated the relationship between malposition of the levonorgestrel 52-mg intrauterine device and unfavorable bleeding patterns and pelvic pain. STUDY DESIGN: We performed a large prospective cohort study. Patients seeking a levonorgestrel 52-mg intrauterine device were eligible for inclusion. Transvaginal ultrasonography was performed to check position of the levonorgestrel 52-mg intrauterine device immediately after insertion and 6 weeks later. Patients filled in questionnaires about bleeding pattern and pelvic pain 6 weeks after insertion. RESULTS: From March 2015 to December 2016, we enrolled 500 patients. Data from the transvaginal ultrasonography assessment 6 weeks after insertion were available for 448 patients, and complete data (transvaginal ultrasonography and questionnaire data) were available for 363 patients (72.6%). Malposition rate was 6.3% (28/448 patients). Malposition was seen in 15 of 198 patients (7.6%) with unfavorable bleeding and/or pelvic pain and in 3 of 165 patients (1.8%) with favorable bleeding patterns and no pelvic pain (P=.03).Malposition was seen in 14 of 186 patients (7.5%) with an unfavorable bleeding pattern and in 4 of 177 patients (2.3%) with favorable bleeding patterns (P=.008). Malposition was seen in 5 of 50 patients (10%) with pelvic pain and in 13 of 313 patients (4.2%) without pelvic pain (P=.08). CONCLUSION: The malposition rate of the levonorgestrel 52-mg intrauterine device observed using transvaginal ultrasonography 6 weeks after insertion was 6.3%. If patients have no complaints of unfavorable bleeding and/or pelvic pain, the risk for malposition is low (1.8%) and a routine transvaginal ultrasonography is not necessary. However, if patients experience unfavorable bleeding, a transvaginal ultrasonography should be considered to exclude malposition, because the effect of malposition on contraceptive effectiveness is unsure. Future research should focus on cost-benefit analysis.

Increased MR-guided high intensity focused ultrasound (MR-HIFU) sonication efficiency of uterine fibroids after carbetocin administration.

Purpose: We investigated whether administration of the long-acting uterus stimulant carbetocin increased intra-subject sonication efficiency during Magnetic Resonance image guided High Intensity Focused Ultrasound (MR-HIFU) treatment of uterine fibroids. Method: In this prospective cohort study, thirty women with symptomatic uterine fibroids undergoing MR-HIFU treatment were included between January 2018 and January 2019. Treatment started with three sonications on one side of the uterine fibroid. Subsequently, one ampoule of 1 mL carbetocin (100 µg/mL) was administered intravenously and treatment continued with three sonications on the other side of the uterine fibroid. We compared the intra-subject sonication efficiency, in terms of Energy Efficiency Factor (EEF), thermal dose volume and sonication time to ablate one cm3 of fibroid tissue, before and after carbetocin administration. Adverse events that occurred within 30 min after carbetocin administration were recorded. Results: Sonication efficiency improved after carbetocin administration as indicated by a significant decrease in EEF and sonication time (p = 0.006 and p = 0.001 respectively), and a significant increase in thermal dose volume reached (p = <0.001). Five women (16.7%) experienced temporary tachycardia, one women in combination with headache, within 30 min after carbetocin administration. Conclusion: Administration of the long-acting uterus stimulant carbetocin improved the MR-HIFU treatment intra-subject sonication efficiency in women with symptomatic uterine fibroids.

Comparison of (Cost-)Effectiveness of Magnetic Resonance Image-Guided High-Intensity-Focused Ultrasound With Standard (Minimally) Invasive Fibroid Treatments: Protocol for a Multicenter Randomized Controlled Trial (MYCHOICE).

BACKGROUND: Magnetic resonance image-guided high-intensity-focused ultrasound (MR-HIFU) is a rather new, noninvasive option for the treatment of uterine fibroids. It is safe, effective, and has a very short recovery time. However, a lack of prospectively collected data on long-term (cost-)effectiveness of the MR-HIFU treatment compared with standard uterine fibroid care prevents the MR-HIFU treatment from being reimbursed for this indication. Therefore, at this point, when conservative treatment for uterine fibroid symptoms has failed or is not accepted by patients, standard care includes the more invasive treatments hysterectomy, myomectomy, and uterine artery embolization (UAE). Primary outcomes of currently available data on MR-HIFU treatment often consist of technical outcomes, instead of patient-centered outcomes such as quality of life (QoL), and do not include the use of the latest equipment or most up-to-date treatment strategies. Moreover, data on cost-effectiveness are rare and seldom include data on a societal level such as productivity loss or use of painkillers. Because of the lack of reimbursement, broad clinical implementation has not taken place, nor is the proper role of MR-HIFU in uterine fibroid care sufficiently clear. OBJECTIVE: The objective of our study is to determine the long-term (cost-)effectiveness of MR-HIFU compared with standard (minimally) invasive fibroid treatments. METHODS: The MYCHOICE study is a national, multicenter, open randomized controlled trial with randomization in a 2:1 ratio to MR-HIFU or standard care including hysterectomy, myomectomy, and UAE. The sample size is 240 patients in total. Women are included when they are 18 years or older, in premenopausal stage, diagnosed with symptomatic uterine fibroids, conservative treatment has failed or is not accepted, and eligible for MR-HIFU. Primary outcomes of the study are QoL 24 months after treatment and costs of treatment including direct health care costs, loss of productivity, and patient costs. RESULTS: Inclusion for the MYCHOICE study started in November 2020 and enrollment will continue until 2024. Data collection is expected to be completed in 2026. CONCLUSIONS: By collecting data on the long-term (cost-)effectiveness of the MR-HIFU treatment in comparison to current standard fibroid care, we provide currently unavailable evidence about the proper place of MR-HIFU in the fibroid treatment spectrum. This will also facilitate reimbursement and inclusion of MR-HIFU in (inter)national uterine fibroid care guidelines.

Perioperative findings and complications in Essure® removal surgery.

OBJECTIVE: To analyze perioperative findings and complications in surgical removal of Essure® microinserts. STUDY DESIGN: A prospective cohort study of 274 patients who underwent surgical removal of Essure® microinserts. Outcomes of the surgical procedures and complications were entered into a digital case report form (CRF) by the surgeon and registered in an online database. Results were analyzed through IBM SPSS Statistics using descriptive statistical methods. RESULTS: During laparoscopic inspection in 15.4 % of fallopian tubes (n = 80) a chicken wing sign (the fallopian tube folding over the most distal part of the microinsert) was seen. Partial tubal perforation and total tubal perforation with migration of the microinsert out of the fallopian tube were seen in respectively 1.9 % (n = 10) and 0.2 % (n = 1) of cases. The microinserts were removed by laparoscopic tubotomy and extraction, followed by bilateral salpingectomy in 91.2 % of cases. In 7.3 % of cases (n = 20) a hysterectomy and bilateral salpingectomy was performed for additional indications than solely Essure® removal. Four microinserts were taken out entirely by means of hysteroscopy (1.5 %). We did not see major surgery related complications, however we found a risk of minor complications during or after surgery of respectively 1.6 % (n = 4) and 3.9 % (n = 10). CONCLUSIONS: During laparoscopic inspection, abnormalities were seen in 22.8 % (n = 119) of fallopian tubes, of which the chicken wing sign was the most common. Partial and total tubal perforation with migration of the microinsert were rare. The complication rate of Essure® removal surgery in our prospective study is low and complications are minor, without any major complication. However, while counseling patients with a request for surgical removal of Essure® microinserts, these results should be mentioned.

Systematic review of reproductive outcomes after High Intensity Focused Ultrasound treatment of uterine fibroids.

PURPOSE: Myomectomy is currently the gold standard for the treatment of uterine fibroids in women who desire pregnancy. However, this surgical fibroid removal has a long convalescence. Promising alternatives may be non-invasive High Intensity Focused Ultrasound (HIFU) under either MRI (MR-HIFU) or ultrasound guidance (USgHIFU). In this systematic review, an overview is provided of reproductive outcomes after these two relatively new ablation techniques. METHOD: A systematic literature search was performed to identify studies reporting reproductive outcomes after HIFU treatment of fibroids. Only peer reviewed, full papers were included. Outcomes included pregnancy-, live-birth- miscarriage and caesarian section rate, time to conceive, reported complications, and possible prognostic factors. RESULTS: In total 21 studies were included. Fourteen studies reported 124 pregnancies after MR-HIFU. Two placenta previas and no uterus ruptures were reported. Pregnancy rates were only retrospectively collected and ranged between 7% and 36%. Miscarriage rate in the oldest and largest prospective registry was 39%. After USgHIFU 366 pregnancies were reported with one fetal intrauterine death, six placenta previas and no uterus ruptures. The only prospective study reported a pregnancy rate of 47% and a miscarriage rate of 11%. Possible prognostic factors like age were not available in most studies. CONCLUSIONS: Based on the heterogeneous data currently available, reproductive outcomes after HIFU appear non-inferior to outcomes after the current standard of care. However, a (randomized) controlled trial comparing reproductive outcomes after HIFU and standard care is necessary to provide sufficient evidence on the preferred fibroid treatment for women with a pregnancy wish.

Live births after Asherman syndrome treatment.

OBJECTIVE: To study the reproductive outcomes after surgical management of women with Asherman syndrome (AS). DESIGN: Cohort study. SETTING: International referral hospital for women with AS. PATIENT(S): A total of 500 women who were diagnosed with and treated for AS between January 2003 and December 2016 and followed for a minimum of 2 years. INTERVENTION(S): Hysteroscopic adhesiolysis using conventional instruments with concomitant fluoroscopy as a guidance method. MAIN OUTCOME MEASURE(S): Live birth rate. RESULT(S): Of the 500 women included in the cohort, 569 pregnancies were achieved within 3 years after surgery. The miscarriage rate was 33.0%, and the live birth rate was 67.4%. Age, the causal procedure, and at least one miscarriage after adhesiolysis strongly predicted the outcome of a live birth. CONCLUSION(S): The overall take-home newborn rate was 67.4% after adhesiolysis in women with AS. Women with AS who are relatively young, with a first-trimester procedure preceding AS, and with low grades of adhesions and no miscarriage after adhesiolysis have the best chance of a newborn delivery.

Patient-derived organoids model cervical tissue dynamics and viral oncogenesis in cervical cancer.

Cervical cancer is a common gynecological malignancy often caused by high-risk human papillomavirus. There is a paucity of human-derived culture systems to study the cervical epithelium and the cancers derived thereof. Here we describe a long-term culturing protocol for ecto- and endocervical epithelia that generates 3D organoids that stably recapitulate the two tissues of origin. As evidenced for HSV-1, organoid-based cervical models may serve to study sexually transmitted infections. Starting from Pap brush material, a small biobank of tumoroids derived from affected individuals was established that retained the causative human papillomavirus (HPV) genomes. One of these uniquely carried the poorly characterized HPV30 subtype, implying a potential role in carcinogenesis. The tumoroids displayed differential responses to common chemotherapeutic agents and grew as xenografts in mice. This study describes an experimental platform for cervical (cancer) research and for future personalized medicine approaches.

The Needs of Dutch Women During Decision-Making About Treatment for Miscarriage.

OBJECTIVE: To explore the needs of women during decision-making about treatment for miscarriage. DESIGN: Descriptive qualitative design. SETTINGS: University and teaching hospitals in the Netherlands. PARTICIPANTS: We selected a purposive sample of 16 women who needed treatment for miscarriage from an electronic patient file system. We ensured maximum variation by sampling in different hospitals and selecting women with different ages, numbers of children, miscarriage histories, treatment types, and educational levels. METHODS: We conducted face-to-face individual, semistructured interviews and used thematic analysis to identify, analyze, and describe themes. RESULTS: We identified one overarching theme, Decision Based on Reason and Emotion, and three related subthemes: Certainty, Information, and SupportFrom Environment. CONCLUSION: Health care professionals should be aware of how women's decision-making is structured in the context of treatment choices for miscarriage, and discussion regarding treatment should address reason and emotion.

Levonorgestrel-releasing intrauterine system versus endometrial ablation for heavy menstrual bleeding.

BACKGROUND: Heavy menstrual bleeding affects the physical functioning and social well-being of many women. The levonorgestrel-releasing intrauterine system and endometrial ablation are 2 frequently applied treatments in women with heavy menstrual bleeding. OBJECTIVE: This study aimed to compare the effectiveness of the levonorgestrel-releasing intrauterine system with endometrial ablation in women with heavy menstrual bleeding. STUDY DESIGN: This multicenter, randomized controlled, noninferiority trial was performed in 26 hospitals and in a network of general practices in the Netherlands. Women with heavy menstrual bleeding, aged 34 years and older, without a pregnancy wish or intracavitary pathology were randomly allocated to treatment with either the levonorgestrel-releasing intrauterine system (Mirena) or endometrial ablation, performed with a bipolar radiofrequency device (NovaSure). The primary outcome was blood loss at 24 months, measured with a Pictorial Blood Loss Assessment Chart score. Secondary outcomes included reintervention rates, patient satisfaction, quality of life, and sexual function. RESULTS: We registered 645 women as eligible, of whom 270 women provided informed consent. Of these, 132 women were allocated to the levonorgestrel-releasing intrauterine system (baseline Pictorial Blood Loss Assessment Chart score, 616) and 138 women to endometrial ablation (baseline Pictorial Blood Loss Assessment Chart score, 630). At 24 months, mean Pictorial Blood Loss Assessment Chart scores were 64.8 in the levonorgestrel-releasing intrauterine system group and 14.2 in the endometrial ablation group (difference, 50.5 points; 95% confidence interval, 4.3-96.7; noninferiority, P=.87 [25 Pictorial Blood Loss Assessment Chart point margin]). Compared with 14 women (10%) in the endometrial ablation group, 34 women (27%) underwent a surgical reintervention in the levonorgestrel-releasing intrauterine system group (relative risk, 2.64; 95% confidence interval, 1.49-4.68). There was no significant difference in patient satisfaction and quality of life between the groups. CONCLUSION: Both the levonorgestrel-releasing intrauterine system and endometrial ablation strategies lead to a large decrease in menstrual blood loss in women with heavy menstrual bleeding, with comparable quality of life scores after treatment. Nevertheless, there was a significant difference in menstrual blood loss in favor of endometrial ablation, and we could not demonstrate noninferiority of starting with the levonorgestrel-releasing intrauterine system. Women who start with the levonorgestrel-releasing intrauterine system, a reversible and less invasive treatment, are at an increased risk of needing additional treatment compared with women who start with endometrial ablation. The results of this study will enable physicians to provide women with heavy menstrual bleeding with the evidence to make a well-informed decision between the 2 treatments.

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.

Long-term follow-up after successful Essure sterilization: evaluation of patient satisfaction, symptoms, and the influence of negative publicity.

OBJECTIVE: To evaluate long-term patient satisfaction and symptoms after successful Essure sterilization and the influence of negative publicity on patients' opinion. DESIGN: Survey study. SETTING: Two nonacademic hospitals. PATIENT(S): All 924 women who underwent successful Essure sterilization between 2003 and 2009. INTERVENTION(S): A questionnaire was sent between 2008 and 2010 and in 2018. MAIN OUTCOME MEASURE(S): Patient satisfaction, symptoms, and the influence of negative publicity on patients' opinion of Essure sterilization. RESULT(S): After a median follow-up of 29 months, 689 of 924 women (74.6%) responded to the first questionnaire. Of these women, 673 of 689 (97.7%) was satisfied with their Essure sterilization and 607 of 689 (88.1%) recommended Essure sterilization to other women. Of the 689 women, 71 (10.3%) reported having symptoms after Essure sterilization for which they had to consult a physician. Most reported symptoms were menstrual and abdominal pain. After a median follow-up of 144 months, 317 of 577 women (54.9%) responded to the second questionnaire. A total of 157 of 317 (49.5%) women reported having symptoms and in 51 (16.1%) women the Essure devices were surgically removed. Among these women, 29 (57%) reported that their symptoms disappeared afterward and 33 of 51 (65%) women reported that negative publicity had somehow affected their decision to undergo surgery. CONCLUSION(S): After a follow-up of 144 months, approximately 50% of the women reported having symptoms and 16% underwent Essure removal surgery. Publicity had a negative influence on patients' opinion of Essure sterilization, as well as an effect on the decision-making process regarding Essure removal. These data are important when facing women with possible Essure-related complaints.

Removal of Essure Sterilization Devices: A Retrospective Cohort Study in the Netherlands.

STUDY OBJECTIVE: To analyze short-term effectiveness and symptom resolution after surgical removal of Essure (Bayer AG, Leverkusen, Germany) sterilization devices. DESIGN: A single-center retrospective cohort study (Canadian Task Force classification III). SETTING: A large secondary care teaching hospital in the Netherlands. PATIENTS: All patients who underwent surgical removal of Essure devices between January 2009 and December 2015. INTERVENTIONS: Surgical removal of Essure devices was predominantly performed by laparoscopic surgery. In the majority of patients, Essure devices were removed by performing bilateral salpingectomy (66.6%). MEASUREMENTS AND MAIN RESULTS: Data regarding patient characteristics, symptoms, the insertion procedure, the removal procedure, results of the pathological assessment, and follow-up were extracted from patient files. A total of 93 patients had Essure devices removed in the selected period. The onset of symptoms after Essure sterilization was variable. The most frequently reported symptom was abdominal pain (69.9%) followed by lower back pain and fatigue. Most patients reported multiple symptoms; 39.8% of women reported complete relief of symptoms after removal surgery, whereas 15.1% did not notice any relief in symptoms. CONCLUSION: Six weeks after removal surgery, 39.8% of patients reported complete resolution of symptoms. Further research to reported symptoms after Essure sterilization and symptom resolution after removal surgery is necessary to inform both patients and gynecologists in order to make a well-considered decision about taking the risks of (major) surgery and the expected benefits of removal.

Magnetic Resonance Imaging-Guided High-Intensity Focused Ultrasound is a Noninvasive Treatment Modality for Patients with Abdominal Wall Endometriosis.

Two women (29 and 35 years of age) presented with an abdominal wall mass in close proximity to a cesarean scar. The main complaints consisted of pain at the site of the mass with catamenial exacerbations. Clinical and imaging findings were consistent with abdominal wall endometriosis in both cases. First, hormonal treatment was started, which proved unsuccessful. Typically, at this point, the proposed treatment would be wide surgical excision. Alternatively, magnetic resonance imaging-guided high-intensity focused ultrasound treatment was offered with the goal to diminish pain complaints noninvasively. Upon treatment, both patients' complaints diminished although some cyclic pain persisted. Overall, these cases show that magnetic resonance imaging-guided high-intensity focused ultrasound can be used as a noninvasive treatment method to reduce complaints in patients with abdominal wall endometriosis.
