Abstract
PURPOSE To determine the effectiveness, safety, and participant satisfaction with endometrial ablation by bipolar energy (NovaSure®) in the treatment of heavy menstrual bleeding (HMB), and to investigate factors associated with poorer outcomes. METHODS Multicenter retrospective observational study based on medical record review of the outcomes related to endometrial ablation by the bipolar-energy technique procedure to treat HMB in the setting of three university teaching hospitals in Spain. RESULTS A total of 333 women were included in the study. Most bipolar-energy ablations were successful (85.12%; n = 269 out of 316), with amenorrhea the most frequent outcome (39.6%, n = 131 out of 316). The majority of participants had no complications (95.5%; n = 317 out of 332), and of those who did, only 2.1% were related to the technique. No further treatment was required for HMB in 82.8% of women (n = 274 out of 331), and surgery was avoided in 91.8%; only 5.9% of women underwent ablation-related hysterectomy. In women with previous transverse cesarean sections (CS), 91.0% avoided subsequent surgical treatment. Eighty-six percent of women (n = 221 out of 257) were satisfied with the procedure. CONCLUSION Bipolar-energy ablation is very effective and safe for the treatment of HMB and yielded a high rate of participant satisfaction in our setting. The presence of comorbidities or previous CS may slightly reduce the effectiveness of the method, while performing concomitant surgery (mainly curettage) increases the rate of complications. Notably, despite the known increased risk of hysterectomy, most participants with previous CSs who underwent ablation avoided major surgery.

Abstract
This retrospective study assessed the efficacy and long-term satisfaction of radiofrequency endometrial ablation outside the context of clinical trials in 408 women, and compared the outcome between office-setting (211, 52%) and day-case procedures under general anaesthetics (197, 48%). The Kaplan Meir time-to-event analysis showed that the cumulative number of women undergoing surgical re-intervention was 32 with a probability of 9.4% (95% CI: 6.3 - 12.5%) at 2-years, and 45 with a probability of 14.5% (95% CI: 10.3 - 18.2%) at 5-years. There was no statistically significant difference in the re-intervention rate between office and day-case groups (HR = 0.7, 95% CI: 0.68 - 3.1, p = .3). The satisfaction rate, measured by Visual Analogue Scale, was not statistically different (p = .5) between office (109; 80.7%) and day-case (96; 82.8%) groups. This study showed lower surgical re-intervention rate than previously reported in observational studies, and high rates of long-term women satisfaction. The outcomes were similar in office and day-case settings.Impact statementWhat is already known on this subject? Previous studies have shown the safety and effectiveness of radiofrequency endometrial ablation for treating heavy periods. However, studies investigating it, outside clinical trials, either included a small sample size, a short-term follow-up, poor reporting so that it is impossible to judge whether some women underwent re-intervention in another centre, failed to discriminate in analysis between second-generation techniques, or assessed only short-term satisfaction.What do the results of this study add? This is the largest series reported from a single centre and the first study reporting long-term satisfaction in women, outside clinical trials. Surgical re-intervention was used as the primary outcome measure which is an objective measure rather than the change in the monthly flow which is rather subjective. More importantly, the study records the similarity, in the outcome and women's satisfaction rate, between office and day-case procedures under general anaesthetics.What are the implications of these findings for clinical practice and/or further research? Endometrial ablation service is widely implemented in office-setting in the UK. We hope the result of this study encourages implementation on a larger scale in office across centres in the world with its multiple advantages both to women and service alike.

Abstract
Aim: To evaluate the safety and efficacy of a radiofrequency ablation system with a novel endometrial tip (RFA-EMT) for the management of heavy menstrual bleeding (HMB) or abnormal uterine bleeding (AUB).Methods: This is a prospective study including a total of 38 premenopausal women with heavy menstrual bleeding (HMB) or abnormal uterine bleeding (AUB) that failed to respond to medical therapy. Hysteroscopic evaluation and curettage biopsy were performed just before the procedure. The procedure was timed to occur during the early proliferative phase (cycle days 4-10). RFA-EMT procedures were performed by a single surgeon with the patient under general anesthesia with a laryngeal mask airway. Primary outcome was reduction in bleeding, reported as amenorrhea, hypomenorrhea, and eumenorrhea, which were measured via hemoglobin level and pictorial blood assessment chart (PBAC) score. Secondary outcomes were adverse events, dysmenorrhea with numeric rating scale (NRS) score, and endometrial thickening in the early proliferative phase, as assessed by transvaginal ultrasonography.Results: There were no peri- or post-procedural complications. Combined amenorrhea, hypomenorrhea, and eumenorrhea rates at 3 and 6 months were 97.4% and 100%, respectively. The hemoglobin level was significantly increased, and the PBAC score, NRS score, and endometrial thickening were significantly decreased after 3 months. These trends were maintained for 6 months after the procedure.Conclusion: RFA-EMT, a new technique, is safe and effective for women with HMB or AUB for which medical therapy has failed.

Histologic findings in hysterectomies after endometrial ablation. Pathol Res Pract 2020; 216:152992. [PMID: 32475645 DOI: 10.1016/j.prp.2020.152992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2020] [Accepted: 04/22/2020] [Indexed: 11/23/2022]
Abstract
BACKGROUND Endometrial ablation for abnormal uterine bleeding is used as a less invasive alternative to hysterectomy, however, in cases of treatment failure hysterectomy may be finally performed. The histologic changes in these post-treatment uteri are not well-described. OBJECTIVE To describe the histological findings in post-endometrial ablation uteri. STUDY DESIGN During a ten-year period, 321 patients were treated with endometrial ablation. Twenty-five patients (7.8%), 10 treated with NovaSure® and 15 treated with ThermaChoice® endometrial ablation were finally subjected to hysterectomy mostly due to persistent uterine bleeding. Histologic features of these hysterectomies are described. RESULTS The patients' age ranged from 33 to 73 years (mean 44.5) and 34-53 (mean 42) for the NovaSure® and ThermaChoice® group, respectively. The time from endometrial ablation to hysterectomy was 2-24 months (mean 8.8) and 2-60 months (mean 23.2) for the two groups, respectively (p = 0.01). Hysterectomies performed later (mean 22 months) showed no fibrosis (p = 0.04) compared with those performed earlier (mean 5 months). Endometrial lining was found more frequently in hysterectomies performed later (mean 13 months) than those performed earlier (mean 2 months, p = 0.0004). Abundant necrotic tissue of myometrial origin was found in 28% of the cases, but it was not associated with the time of hysterectomy (p = 0.2). A zonation effect and vascular changes also seen. Granulomatous reaction was not found. Ten patients (40%) harbored adenomyosis and another three (12%) extensive leiomyomas/diffuse leiomyomatosis. CONCLUSION Necrosis, fibrosis and vascular changes are found during the first year of post-thermal uterine effect. Hysterectomies performed later show less prominent changes and almost normal endometrial lining. Adenomyosis is found in an important part of post-endometrial ablation hysterectomies.

Abstract
OBJECTIVE The study objective was to retrospectively evaluate the efficacy and safety of radiofrequency endometrial ablation in treating heavy menstrual bleeding (HMB) in women with chronic renal failure (CRF). METHOD Fifty-eight patients with CRF undergoing radiofrequency endometrial ablation in our hospital between January 2013 and July 2017 and for whom complete follow-up data were available were included. Outcome measures included amenorrhea, treatment failure and operative complications. RESULTS The mean patient age was 41.4 ± 7.7 years, the mean preoperative hemoglobin level was 69.6 ± 19.3 g/dL, the mean preoperative serum creatinine level was 879.1 ± 415.4 µmol/L, and the mean urea level was 18.2 ± 7.1 mmol/L. The mean treatment time for radiofrequency endometrial ablation was 61.7 ± 18.8 s. The median volume of estimated blood loss during the procedure was 10 mL (a range of 2-50 mL). On average, the study subjects were monitored for 24.4 months (a range of 6-60 months). The average amenorrhea rate was 89.7%. Only 2 (3.4%) patients required additional gynecologic surgery after endometrial ablation. Intra- and postoperative complications were not observed. CONCLUSION Radiofrequency endometrial ablation was demonstrated to be safe and effective for the treatment of HMB in women with CRF.

Abstract
The rapid evolution in ambulatory hysteroscopy (AH) has transformed the approach to diagnose and manage abnormal uterine bleeding (AUB). The medical management in primary care remains the mainstay for initial treatment of this common presentation; however, many women are referred to secondary care for further evaluation. To confirm the diagnosis of suspected intrauterine pathology, the traditional diagnostic tool of day case hysteroscopy and dilatation and curettage in a hospital setting under general anesthesia is now no longer required. The combination of ultrasound diagnostics and modern AH now allows thorough evaluation of uterine cavity in an outpatient setting. Advent of miniature hysteroscopic operative systems has revolutionized the ways in which clinicians can not only diagnose but also treat menstrual disorders such as heavy menstrual bleeding, intermenstrual bleeding and postmenopausal bleeding in most women predominantly in a one-stop clinic. This review discussed the approach to manage women presenting with AUB with a focus on the role of AH in the diagnosis and treatment of this common condition in an outpatient setting.

Utility of anesthetic block for endometrial ablation pain: a randomized controlled trial. Am J Obstet Gynecol 2018; 218:225.e1-225.e11.

Abstract
BACKGROUND Second-generation endometrial ablation has been demonstrated safe for abnormal uterine bleeding treatment, in premenopausal women who have completed childbearing, in short-stay surgical centers and in physicians' offices. However, no standard regarding anesthesia exists, and practice varies depending on physician or patient preference and hospital policy and setting. OBJECTIVE The aim of this study was to evaluate whether local anesthetic, in combination with general anesthesia, affects postoperative pain and associated narcotic use following endometrial ablation. MATERIALS AND METHODS This was a single-center single-blind randomized controlled trial conducted in an academic-affiliated community hospital. A total of 84 English-speaking premenopausal women, aged 30 to 55 years, who were undergoing outpatient endometrial ablation for benign disease were randomized to receive standardized paracervical injection of 20 mL 0.25% bupivacaine (treatment group) or 20 mL normal saline solution (control group) upon completion of ablation. The study was designed to test a 40% 1-hour mean visual analog scale (VAS) pain score difference with an average standard deviation of 75% of both groups' mean VAS scores, using a 2-tailed test, a type I error of 5%, and statistical power of 80%. A sample of 36 patients per study group was required. Assuming a 15% attrition rate, the study enrolled 42 patients per study arm randomized in blocks of 2 (84 total). Two-tailed cross-tabulations with Fisher exact significance values where appropriate and Student t tests were used to compare patient characteristics. Backward stepwise regressions were conducted to control for confounding. RESULTS Between April 2016 and February 2017, a total of 108 women scheduled for endometrial ablation were screened (refusals, n = 21; ineligible, n = 3) to determine whether there were meaningful differences in postoperative VAS pain scores and postoperative narcotic use. Of the 84 randomized women, 2 age-ineligible women were excluded. Intent-to-treat analyses included 1 incorrect randomization (in which the provider consciously decided to provide analgesia regardless of the protocol, after which the provider was excluded from further study participation) and 3 women having no ablation because of operative difficulties. Three were lost to second-day follow-up. Treatment group patients (n = 41) experienced 1.3 points lower 1-hour postoperative VAS pain scores than the control group (n = 41, P = .02). The difference diminished by 4 hours (P = .31) and was negligible by 8 hours (P = .62). Treatment group patients used 3.6 less morphine equivalents of postoperative pain medication (P = .05). Regression analyses controlled for confounding reduced the 1-hour postoperative treatment group pain score difference to 0.8 (confidence interval [CI], -0.6 to 0.1) but slightly increased the average postoperative morphine equivalents to 3.7 (CI, -6.8 to -0.7). CONCLUSION This randomized controlled trial found that local anesthetic with low risk for complications, used in conjunction with general anesthesia, decreased postoperative pain at 1 hour and significantly reduced postoperative narcotic use following endometrial ablation. Further research is needed to determine whether the study results are generalizable and whether post procedure is the best time to administer the paracervical block to decrease endometrial ablation pain.

Abstract
Endometrial ablation (EA) includes a spectrum of procedures performed with or without hysteroscopic direction, designed to destroy the endometrium for the treatment of the symptom of heavy menstrual bleeding (HMB) secondary to a spectrum of causes, but most commonly those that are endometrial in origin (AUB-E) or ovulatory disorders (AUB-O). Resectoscopic endometrial ablation (REA) is often mistakenly referred to as the "first generation" technique, while proprietary devices that do not use the resectoscope (nonresectoscopic EA or NREA) are often misperceived as "second generation" devices. Indeed, the origins of NREA date back to the late 19th century with the use of steam, and the early and mid 20th century, when radiofrequency and cryotherapy based NREA techniques were published - long before the resectoscope was used and reported. The NREA devices have also been mislabeled as "global", a misleading term borrowed from the marketing departments of device manufacturers - there is no device that predictably treats the entire endometrium. Consequently, none can be construed as being "global". Instead, EA is a procedure designed for women as an alternative to hysterectomy, or, perhaps, medical therapy, when future fertility is no longer desired. Women who select EA should anticipate a relatively low risk procedure that will likely reduce their HMB to normal levels or less. This paper will review the spectrum of EA techniques and devices, their clinical outcomes and adverse events, and explore their value compared to hysterectomy and selected medical therapies.

Abstract
Endometrial ablation, first reported in the 19th century, has gained wide acceptance in the gynecologic community as an important tool for the management of abnormal uterine bleeding when medical management has been unsuccessful or contraindicated. The introduction of global endometrial ablation (GEA) devices beginning in 1997 has provided unsurpassed safety addressing many of the concerns associated with their resectoscopic predecessors. As of this writing the GEA market has surpassed a half-million devices in the United States per annum and has an expected compound annual growth rate (CAGR) projected to be 5.5% from 2016 to 2024. While the short term safety and efficacy of these devices has been reported in numerous clinical trials we only recently are becoming aware of the high incidence of late-onset endometrial ablation failures (LOEAFs) associated with these procedures. Currently, about a quarter of women who undergo a GEA procedure will eventually require a hysterectomy while an unknown number have less than satisfactory results. In order to reduce these suboptimal outcomes physicians must better understand the etiology and risk factors that predispose a patient toward the development of LOEAF as well as current knowledge of patient and procedure selection for EA as well as treatment options for these delayed complications. Over 500,000 endometrial ablations (EAs) are performed in the U. S. each year. Late-onset endometrial ablation failures (LOEAFs) are the most common complication of EA. 25% of women who undergo EA will require hysterectomy within 5 years. Reducing the incidence of LOEAFs requires improved patient selection for EA. Ultrasound-guided reoperative hysteroscopic surgery (UGRHS) reduces the need hysterectomy following LOEAF.

Abstract
Endometrial ablation procedures are growing in popularity for the treatment of menorrhagia and dysmenorrhea. Sonography is the modality of choice in the evaluation of patients prior to ablation and as a follow-up for any postprocedure complications. After ablation, conditions including hematometra, postablation tubal sterilization syndrome, postablation endometriosis, and pregnancy complications have been documented. Sonographers should be aware of the conditions associated with endometrial ablations and the variety of sonographic findings that may be present.

Abstract
AIM Abnormal uterine bleeding (AUB) occurs in 10-30% of women of reproductive age and up to 61% of cirrhotic women. We evaluated the efficacy and safety of endometrial ablation (NovaSure therapy) for AUB in cirrhotic women. METHODS This prospective, two-arm, observational study enrolled patients for NovaSure treatment, and they were followed for 12 months. Primary measurements were the amenorrhea rate and changes of pictorial blood loss assessment chart (PBLAC) scores at 1-month post-therapy. Key secondary end-points included the longevity of amenorrhea at 12 months, safety profile, and progression of cirrhosis. RESULTS Among 88 women, 26 were cirrhotic and 62 were non-cirrhotic. At 1-month post-NovaSure treatment, a significant reduction of mean PBLAC scores was observed in cirrhotic patients compared to those at baseline (0.4 ± 1.3 vs 215.2 ± 410.9, P < 0.001), and the amenorrhea rate was 88.5%. The efficacy outcomes of the PBLAC scores and amenorrhea rate were maintained until the end of the 12-month follow-up. A significant improvement in quality of life scores was observed 1-month post-therapy compared to those at baseline (5.4 ± 3.1 vs 20.5 ± 5.5, P < 0.001). Patients' satisfaction rates were 100% and 92.31% at 6 and 12 months, respectively. The aforementioned outcomes were comparable with those in non-cirrhotic patients. No significant progression of cirrhosis or safety concern was reported. CONCLUSION Cirrhotic patients on NovaSure therapy had a high rate of amenorrhea 1-month post-treatment, which maintained longevity for 12 months. The safety profile was similar to that in non-cirrhotic patients.

Abstract
OBJECTIVES Abnormal uterine bleeding (AUB) interferes with physical, emotional, and social well-being, impacting the quality of life of more than 10 million women in the USA. Hysterectomy, the most common surgical treatment of AUB, has significant morbidity, low mortality, long recovery, and high associated health care costs. Global endometrial ablation (GEA) provides a surgical alternative with reduced morbidity, cost, and recovery time. The NovaSure(®) system utilizes unique radiofrequency impedance-based GEA technology. This study evaluated cost effectiveness of AUB treatment with NovaSure ablation versus other GEA modalities and versus hysterectomy from the US commercial and Medicaid payer perspectives. METHODS A health state transition (semi-Markov) model was developed using epidemiologic, clinical, and economic data from commercial and Medicaid claims database analyses, supplemented by published literature. Three hypothetical cohorts of women receiving AUB interventions were simulated over 1-, 3-, and 5-year horizons to evaluate clinical and economic outcomes for NovaSure, other GEA modalities, and hysterectomy. RESULTS Model analyses show lower costs for NovaSure-treated patients than for those treated with other GEA modalities or hysterectomy over all time frames under commercial payer and Medicaid perspectives. By Year 3, cost savings versus other GEA were $930 (commercial) and $3,000 (Medicaid); cost savings versus hysterectomy were $6,500 (commercial) and $8,900 (Medicaid). Coinciding with a 43%-71% reduction in need for re-ablation, there were 69%-88% fewer intervention/reintervention complications for NovaSure-treated patients versus other GEA modalities, and 82%-91% fewer versus hysterectomy. Furthermore, NovaSure-treated patients had fewer days of work absence and short-term disability. Cost-effectiveness metrics showed NovaSure treatment as economically dominant over other GEA modalities in all circumstances. With few exceptions, similar results were shown for NovaSure treatment versus hysterectomy. CONCLUSION Model results demonstrate strong financial favorability for NovaSure ablation versus other GEA modalities and hysterectomy from commercial and Medicaid payer perspectives. Results will interest clinicians, health care payers, and self-insured employers striving for cost-effective AUB treatments.

Abstract
Impedance-controlled endometrial ablation (NovaSure) is commonly used to treat premenopausal heavy menstrual bleeding in Lothian, Scotland. Using postal questionnaires, we assessed patient satisfaction, treatment success and post-procedure symptoms in a cohort of women who had NovaSure treatment between January 2007 and May 2009. The response rate was 61.2% (115/188): 90.4% (104/115) of women were satisfied and would recommend the procedure; 36.8% (42/114) of women were amenorrhoeic at follow-up (mean = 497 days) and NovaSure significantly improved levels of both menstrual bleeding and pain (p < 0.01). Of the women, 67.0% (77/115) reported symptoms such as discomfort, vaginal discharge and bleeding/spotting within 6 weeks following NovaSure. A total of 13.9% (16/115) required further treatment following NovaSure, including hysterectomy. Patient satisfaction with NovaSure was high. Preoperative counselling needs to include information on character and duration of postoperative symptoms. Future research could compare patient satisfaction and clinical outcomes between NovaSure and the levonorgestrel-releasing intrauterine system.

Abstract
Severe Abnormal Uterine Bleeding (SAUB) is a common gynecological disorder. The clinical characteristics include disordered menstrual cycle and massive bleeding that can cause anemia or secondary infection. Current treatment mainly relies on drug therapy or surgical removal of the uterus, each having its significant disadvantages. How to preserve the uterus, reduce the pain from surgery, and achieve better treatment effects have been well known but remaining as unresolved issues. This study aims at evaluating two types of radiofrequency (RF) thermocoagulation procedures for the treatment of SAUB: the RF-A procedure group included 25 SAUB patients ≥45 years of age treated for amenorrhea; the RF-B procedure group included 51 patients at <45 years of age treated for the control of excessive bleeding. Post-treatment ratings of menstrual satisfaction and pre-/post-treatment menstrual scores-pictorial blood loss assessment chart (PBAC)-and hemoglobin levels were collected; and the mean length of follow-up was 72 months. Also, 38 SAUB patients treated with standard drug regimens served as a control group. The results of the study showed that following RF treatment, the average long-term patient menstrual satisfaction was greater than 92 %. In both the RF groups, PBAC scores and hemoglobin levels were significantly improved from baseline (p < .05). Compared with the control group, PBAC scores and hemoglobin levels were also significantly better for the RF groups at 6-24-month post-operation. Patients experienced no hysterectomy in association with the RF procedures. In conclusion, this pilot study suggests that the novel RF procedures are both safe and effective in treating patients with SAUB. Further investigation is necessary to evaluate their application in broader clinical indication.
