Pressure-Induced Fibroid Ischemia: First-In-Human Experience with a Novel Device for Laparoscopic Treatment of Symptomatic Uterine Fibroids.

The purpose of this study was to assess the feasibility of use of a novel uterine fibroid treatment device hypothesized to cause fibroid infarction by increasing intra-tumoral pressure. Between August 2019 and January 2020, 21 uterine fibroids were treated in 16 symptomatic pre-menopausal black women. Pelvic magnetic resonance imaging was performed before the procedure, a day after the procedure and at 1, 3, 6, and 12 months. The subjects were also followed for clinical outcomes and quality of life up to 12 months at a single investigational site. At 3 months, the mean reduction in the fibroid volume was 36.3% (P = .002). Incremental reduction in volume peaked at the end of the follow-up, at the 12-month mark (60.4%; P = .008). There were no procedures in which the users failed to perform laparoscopic pressure suturing of fibroids with the pressure-induced fibroid ischemia device. Improvement in the quality of life was evident in the Health-Related Quality of Life total, Energy/Mood, Control, and Sexual Function domains of the Uterine Fibroid Symptom and Quality of Life questionnaire at 3 months post-procedure. Unanticipated risks were not identified. Serious adverse events were not identified. The initial clinical assessment of the pressure-induced fibroid ischemia device supports feasibility of the approach and does not reveal serious safety concerns. Trial is currently being registered retrospectively (This was a feasibility study and therefore registration was not mandatory).

A Prospective, Multicenter, Pivotal Trial to Evaluate the Safety and Effectiveness of the AEGEA Vapor Endometrial Ablation System.

STUDY OBJECTIVE: To evaluate the safety and effectiveness of the AEGEA Vapor System (Aegea Medical System, Menlo Park, CA) for the treatment of heavy menstrual bleeding (HMB). DESIGN: A prospective, multicenter, single-arm, open-label, clinical trial. Follow-up assessments were conducted at 24 hours; 2 weeks; and 3, 6, and 12 months after the endometrial ablation procedure (Canadian Task Force Classification II-1). SETTING: A private practice and outpatient and hospital settings at 15 sites in the United States, Canada, Mexico, and the Netherlands. PATIENTS: One hundred fifty-five premenopausal women aged 30 to 50years with HMB as determined by a pictorial blood loss assessment score ≥150. Preoperative evaluation included ultrasound, sonohysterography or hysteroscopy, and endometrial biopsy. Screening inclusion allowed treatment of up to 12-cm uterine sound lengths and nonobstructing myomata. INTERVENTIONS: Endometrial ablation (120-second treatment time) was performed under varying anesthesia regimens using the vapor system from September 2014 to May 2015. MEASUREMENTS AND MAIN RESULTS: The primary effectiveness end point was the reduction of menstrual blood loss to a pictorial blood loss assessment score ≤75. Success was judged based on the Food and Drug Administration's objective performance criteria, derived from the success rates of the first 5 global endometrial ablation pivotal clinical trials. The secondary effectiveness end points included quality of life and patient satisfaction as assessed using the Menorrhagia Impact Questionnaire and the Aberdeen Menorrhagia Severity Score as well as the need for surgical or medical intervention to treat abnormal bleeding at any time within the first 12 months after treatment. All adverse events, including device- and procedure-related events, were recorded. At 12 months, the primary effectiveness end point was achieved in 78.7% of subjects exceeding the OPC (p = .0004); 90.8% of subjects were satisfied or very satisfied with the treatment. Ninety-nine percent of subjects showed improvement in quality of life scores with an average decrease in the Menorrhagia Impact Questionnaire score by 8.1, 72% had less dysmenorrhea, and 85% of women whose sex lives were affected by their menses reported improvement in their sex lives. There were no reported serious adverse device effects or any reported serious adverse events that were procedure related. CONCLUSION: The AEGEA Vapor System is a safe, effective, and minimally invasive option for performing in-office endometrial ablation under minimal anesthesia for the purpose of treating women who suffer from HMB.

Hysteroscopic Essure Inserts for Permanent Contraception: Extended Follow-Up Results of a Phase III Multicenter International Study.

OBJECTIVE: To describe safety, tolerability, and effectiveness results through 5 years of follow-up of a Phase III trial with Essure inserts. DESIGN: Multicenter, nonrandomized, single-arm international study (Canadian Task Force classification II-3). SETTING: Thirteen clinical study centers in the United States, Europe, and Australia. PATIENTS: A total of 518 previously fertile women seeking permanent contraception. INTERVENTION: The objective of the hysteroscopic sterilization procedure was bilateral Essure insert placement (ESS205 model) and tubal occlusion. Women with satisfactory device location and tube occlusion (based on modified hysterosalpingography [HSG]) were instructed to discontinue alternative contraception and to rely on Essure inserts for permanent contraception. MEASUREMENTS AND MAIN RESULTS: The primary endpoint for the Phase III study was the rate of pregnancies occurring during the first year of relying (i.e., HSG-confirmed occlusion) on the Essure inserts for permanent contraception (i.e., 12 months after HSG). For the full 5 years of follow-up (5 years total of relying on the Essure inserts for contraception), the endpoints of interest were safety, prevention of pregnancy, and satisfaction. No pregnancies were reported among women relying on the Essure inserts who completed the full 5 years of follow-up. As of December 5, 2007, 449 women with successful bilateral placement relying on the Essure inserts contributed a total 24 942 woman-months of follow-up for assessing effectiveness. Overall, the Essure inserts were generally well tolerated, with participant comfort rated as "good" to "excellent" by 99% of women (382 of 385) after 5 years of use. Similarly, overall satisfaction was rated as "somewhat" to "very satisfied" by 98% of women (376 of 384) after 5 years of use. The majority of adverse events reported during the 5 years of follow-up were rated as either "mild" or "moderate" in severity. Three severe events (abdominal pain with very heavy periods and irregular menstrual bleeding) were reported in 2 subjects during follow-up as being "possibly" related to the procedure or the inserts. CONCLUSION: The findings from extended follow-up of this Phase III trial with Essure inserts further support the effectiveness, tolerability, and satisfaction of this nonhormonal, nonincisional option for permanent contraception.

Three-year outcome of the Halt trial: a prospective analysis of radiofrequency volumetric thermal ablation of myomas.

STUDY OBJECTIVE: To analyze the clinical success of radiofrequency volumetric thermal ablation (RFVTA) at 3-year follow-up in terms of subject responses to validated questionnaires and surgical repeat intervention to treat myomas. DESIGN: Prospective follow-up of patients for 36 months after treatment in a multicenter international trial of outpatient, laparoscopic ultrasound-guided RFVTA of symptomatic uterine myomas (Canadian Task Force classification II-1). SETTING: University hospitals and private surgical centers. PATIENTS: One hundred thirty-five premenopausal women (mean [SD] age, 42.5 [4.6] years; body mass index, 30.5 [6.1]) with symptomatic uterine myomas and objectively confirmed heavy menstrual bleeding (≥ 160 to ≤ 500 mL). INTERVENTIONS: Laparoscopic ultrasound-guided RFVTA. MEASUREMENTS AND MAIN RESULTS: One hundred four participants were followed prospectively for 36 months after treatment of myomas via RFVTA. For 104 evaluable participants with 36-month data, change in mean (SD) symptom severity from baseline (60.2 [18.8]) to 36 months was -32.6 (95% confidence interval, -37.5 to -27.8; p < .001). Health-related quality of life also was improved, from the baseline value of 39.2 (19.2) to 38.6 (95% confidence interval, 33.3 to 43.9; p < .001) at 36 months. Patient-reported Uterine Fibroid Symptom and Health-Related Quality of Life questionnaire subscores demonstrated statistically significant improvement from baseline to 36 months in all categories (Concern, Activities, Energy/Mood, Control, Self-consciousness, and Sexual Function) (p < .001). For the 104 participants with 36-month data, mean state of health scores (EuroQOL-5D Health State Index) improved from a baseline value of 71.0 (19.3) to 86.2 (11.7) at 36 months. The cumulative repeat intervention rate of 11% (14 of 135 participants) at 36 months was well below the possible 25% maximum expected at the beginning of the trial. CONCLUSION: RFVTA of uterine myomas resulted in sustained relief from myoma symptoms and continued improvement in health-related quality of life through 36 months after ablation. The low repeat intervention data through 36 months is a positive outcome for patient well-being.

Sensitivity of myoma imaging using laparoscopic ultrasound compared with magnetic resonance imaging and transvaginal ultrasound.

STUDY OBJECTIVE: To determine the efficacy of laparoscopic ultrasound (LUS) as compared with contrast-enhanced magnetic resonance imaging (CE-MRI) and transvaginal ultrasound (TVUS) in detection of uterine myomas. DESIGN: Retrospective study of imaging methods used in a trial of LUS-guided radiofrequency volumetric thermal ablation in women with symptomatic myomas (Canadian Task Force classification II-2). SETTING: Eleven medical university or private outpatient surgery clinics in the United States (nine sites) and Latin America (two sites). PATIENTS: One hundred thirty-five women with symptomatic myomas and objectively confirmed moderate to severe heavy menstrual bleeding. INTERVENTIONS: LUS-guided radiofrequency volumetric thermal ablation of myomas. MEASUREMENTS AND MAIN RESULTS: Preoperative TVUS scans and CE-MRIs were read at each site, and all CE-MRIs were read by a central reader. LUS-guided scans were obtained intraoperatively by each surgeon by mapping the uterus just before radiofrequency volumetric thermal ablation. The imaging methods and their yields in terms of number of myomas found per subject were as follows: TVUS, 403 myomas (mean [SD] 3 [1.8]; range, 1-8); site CE-MRI, 562 myomas (4.2 [3.8]; range, 1-18); central reader, 619 myomas (4.6 [3.7]; range, 0-20); and LUS, 818 myomas (6.1 [4.9]; range, 1-29) (p < .001). LUS was superior to TVUS, CE-MRI, and the central reader for detection of small (≤1 cm(3)) myomas. Most imaged myomas were intramural: 197 (50.9%) by TVUS, 298 (55.5%) by site CE-MRI, 290 (48.7%) by the central reader, and 386 (48.5%) by LUS. CONCLUSION: Compared with CE-MRI and TVUS, LUS demonstrates the most myomas, regardless of size or type.

Radiofrequency volumetric thermal ablation of fibroids: a prospective, clinical analysis of two years' outcome from the Halt trial.

BACKGROUND: Although most myomas are asymptomatic, quality of life is compromised for many women with uterine fibroid disease. Twelve-month outcomes from the Halt Trial have been reported in the literature. Here we analyze the clinical success of radiofrequency volumetric thermal ablation (RFVTA) of symptomatic uterine fibroids at two years of follow up. METHODS: Prospective, multicenter, outpatient interventional clinical trial of fibroid treatment by RFVTA in 124 premenopausal women (mean age, 42.4 ± 4.4 years) with symptomatic uterine fibroids and objectively confirmed heavy menstrual bleeding (≥160 to ≤500 mL).Outcome measures included: subject responses to validated questionnaires, treatment-emergent adverse events, and surgical re-intervention for fibroids at 24 months postprocedure. Continuous and categorical variables were summarized using descriptive statistics and means and percentages. Comparisons between visits were based on t-tests using repeated measures models. P-values < 0.05, adjusted for multiplicity, were statistically significant. RESULTS: One hundred twelve subjects were followed through 24 months. Change in symptom severity from baseline was -35.7 (95% CI, -40.1 to -31.4; p<.001). Change in health-related quality of life (HRQL) was 40.9 (95% CI, 36.2 to 45.6; p < .001). HRQL subscores also improved significantly from baseline to 24 months in all categories (concern, activities, energy/mood, control, self-consciousness, and sexual function) [p<.001]. Six patients underwent surgical re-intervention for fibroid-related bleeding between 12 and 24 months providing a re-intervention rate of 4.8% (6/124). CONCLUSION: Radiofrequency volumetric thermal ablation of myomas significantly reduces symptom severity and improves quality of life with low surgical re-intervention through 24 months of follow up.

Outpatient procedure for the treatment and relief of symptomatic uterine myomas.

OBJECTIVE: To estimate the safety and efficacy of laparoscopic ultrasound-guided radiofrequency volumetric thermal ablation of uterine myomas in symptomatic women. METHODS: A cohort of 135 premenopausal symptomatic women with uterine myomas, uteri 14 weeks of gestation-sized or less with no single myoma exceeding 7 cm, and objectively confirmed heavy menstrual bleeding participated in this prospective, international trial of outpatient laparoscopic ultrasound-guided radiofrequency volumetric thermal ablation. Bleeding outcomes were measured by alkaline hematin analysis at baseline and again at 3, 6, and 12 months posttreatment. Validated quality-of-life and patient satisfaction scales and objective measurements of uterine and myoma volume were conducted at 3, 6, and 12 months. RESULTS: The mean baseline menstrual blood loss of women in the full analysis set (n=127) was 272.7±82.3 mL. At 3-, 6-, and 12-month follow-ups, mean alkaline hematin and associated menstrual blood loss decreased from baseline levels by 31.8%, 40.7%, and 38.3%, respectively (P<.001, paired t test). Symptom severity decreased from a baseline mean transformed score of 61.1 to 26.6 at 12 months postprocedure (P<.001, paired t test). Health-related quality of life improved from a mean transformed score of 37.3 at baseline to 79.5 at 12 months (P<.001, paired t test). At 12 months postprocedure, total mean myoma volume decreased from baseline by 45.1% (measured by magnetic resonance imaging). There was one serious adverse event (one of 135 [0.7%]) requiring readmission 5 weeks postprocedure and one surgical reintervention for persistent bleeding. Ninety-four percent of the women reported satisfaction with the treatment. CONCLUSION: Radiofrequency volumetric thermal ablation of myomas is well tolerated and results in rapid recovery, high patient satisfaction, improved quality of life, and effective symptom relief.

A 5-day educational program for teaching cervical cancer screening using visual inspection with acetic acid in low-resource settings.

OBJECTIVE: To assess the effectiveness of an educational program in visual inspection with acetic acid (VIA) for cervical cancer screening among healthcare providers in 2 low-resource countries. METHODS: A cohort of multidisciplinary healthcare workers in Uganda and El Salvador were recruited to the study. A pretest was administered before the intervention of a 5-day educational program on VIA. A posttest was performed immediately after the educational program and again at a 6-month follow-up visit to assess retention of knowledge. RESULTS: In total, 42 (93%) of the healthcare workers who participated in the educational program completed the initial posttest evaluation, and 18 (40%) healthcare workers completed the 6-month follow-up evaluation. Mean test scores increased after participation in the training session (62% versus 81%; P<0.001). The self-reported comfort level for identifying cellular abnormalities also increased (2.1 versus 3.3; P<0.001). At 6-month follow-up, the mean test score remained higher than pretest scores (79% versus 57%; P<0.001). There was no significant difference in the initial and 6-month posttest scores (80% versus 79%; P=0.20). CONCLUSION: The educational program in VIA provided healthcare workers with the tools potentially to decrease the morbidity and mortality of cervical cancer in the 2 low-resource countries.

A comparison of novice and experienced physicians performing hysteroscopic sterilization: an analysis of an FDA-mandated trial.

OBJECTIVE: To assess the placement rates for experienced users versus newly trained physicians using the new ESS 305 delivery catheter for the Essure microinsert hysteroscopic sterilization system. DESIGN: Multicenter prospective cohort study. SETTING: Seventy-six sites throughout the U.S. comprising community hospitals, teaching institutions, surgery centers, and office-based practices. PATIENT(S): A total of 578 women seeking hysteroscopic sterilization. INTERVENTION(S): Hysteroscopic sterilization with the ESS 305 device by either experienced or novice physicians. MAIN OUTCOME MEASURE(S): Successful bilateral placement of the Essure 305 device. RESULT(S): A total of 625 patients were recruited with 578 eligible cases performed by 37 newly trained and 39 experienced physicians: 562/578 (97.2%) overall had successful placement, with 98% successful placement rate versus 96.1% for experienced versus novice physicians, respectively. Mean procedural time was 9 minutes (±7 SD), with experienced physicians completing it on average quicker at 7.9 minutes (±5.8 SD) and novices completing it in 10.7 minutes (±8.3 SD). There was no significant association between successful placement with patient characteristics such as body mass index, surgical history, parity, or prior vaginal deliveries observed. CONCLUSION(S): The Essure procedure can be performed quickly and safely with high bilateral placement rates regardless of physician experience or patient characteristics.

Efficacy of a novel educational curriculum using a simulation laboratory on resident performance of hysteroscopic sterilization.

OBJECTIVE: To assess whether a novel educational curriculum using a simulation teaching laboratory improves resident knowledge, comfort with, and surgical performance of hysteroscopic sterilization. DESIGN: An educational prospective, pretest/posttest study. SETTING: The Montefiore Institute of Minimally Invasive Surgery Laboratory. PATIENT(S)/SUBJECT(S): Thirty-four OB/GYN residents in an academic medical center. INTERVENTION(S): Hysteroscopic sterilization simulation laboratory and a brief didactic lecture. MAIN OUTCOME MEASURE(S): Differences in scores on validated skill assessment tools: Task specific checklist, Global Rating Scale (GRS), pass fail assessment, and a multiple-choice examination to evaluate knowledge and attitude. RESULT(S): In the entire cohort improvements were observed on all evaluation tools after the simulation laboratory, with 31% points (SD+/-11.5, 95% confidence interval [CI] 27.3-35.3) higher score on the written evaluation; 63% points (SD+/-15.7, 95% CI 57.8-68.8) higher score on the task specific checklist; and 54% points (SD+/-13.6, 95% CI 48.8-58.3) higher score on the GRS. Higher PGY status was correlated with better pretest performance, but was not statistically significant in posttest scores. Residents reported an improvement in comfort performing the procedure after the laboratory. CONCLUSION(S): Simulation laboratory teaching significantly improved resident knowledge, comfort level, and technical skill performance of hysteroscopic sterilization.

Analysis of pain and satisfaction with office-based hysteroscopic sterilization.

OBJECTIVE: To assess pain and patient satisfaction with office-based hysteroscopic sterilization. DESIGN: This prospective, observational study was designed to assess patient pain perception and satisfaction with office-based hysteroscopic sterilization using the Essure device (Conceptus, Mountain View, CA). SETTING: Faculty practice office at an inner-city urban medical center. PATIENT(S): Women seeking hysteroscopic sterilization. INTERVENTION(S): Office hysteroscopic sterilization under local anesthesia. MAIN OUTCOME MEASURE(S): Pain assessed at the time of the procedure by a 0-10 visual scale and satisfaction by a 1-5 scale. RESULT(S): From June 2003 to June 2006, 209 patients were recruited. The mean scores for average procedural pain, most procedural pain, and average menstrual pain were 2.6+/-2.1, 3.3+/-2.5, and 3.6+/-2.6, respectively. Standardized pain scores revealed that 149 subjects (70%) experienced average pain that was less than or equal to the pain experienced with their menses. Mean satisfaction rating for the procedure was 4.7+/-0.71. CONCLUSION(S): Office-based hysteroscopic sterilization performed with local anesthesia alone is well tolerated, and patients are satisfied with this method for permanent sterilization.

Preserving fertility in invasive cervical adenocarcinoma by abdominal radical trachelectomy and pelvic lymphadenectomy.

A 32-year-old female was diagnosed by loop electrosurgical excision procedure with adenocarcinoma in situ and a focus suspicious for positive lympho-vascular invasion. An abdominal radical trachelectomy was performed to preserve her uterus and fertility. The patient recovered without complications. The patient has had one year of follow-up without any evidences of recurrence. At present, the patient is not actively trying to become pregnant. We concluded that abdominal radical trachelectomy may be a surgical option for early stage cervical cancer treatment in young women who wish to preserve fertility.

Prospective analysis of office-based hysteroscopic sterilization.

STUDY OBJECTIVES: To evaluate the efficacy of performing the Essure hysteroscopic sterilization in an office-based setting. DESIGN: Prospective, longitudinal analysis (Canadian Task Force classification II-3). SETTING: University out-patient office. PATIENTS: All patients undergoing permanent sterilization in our outpatient office who opted for hysteroscopic sterilization were included. INTERVENTIONS: Hysteroscopic placement of the Essure device in an office-based setting with only non-steroidal antiinflammatory drugs and paracervical block. MEASUREMENTS AND MAIN RESULTS: Multiple data points were collected on each patient including demographic data, specific procedural information, and 12-week hysterosalpingogram data. Most of our patients were Hispanic and had an average body mass index of 30.3. Average time to perform the procedure was 12.4 minutes, with the steepest improvement in the first 13 cases. Bilateral placement of the device was successful in 98 (96%) of 102 patients. Of these patients 92 have 12-week hysterosalpingography results (6 patients were lost to follow-up), with 90 (98%) showing bilateral tubal occlusion. There were no intraprocedural or postprocedural complications. CONCLUSION: In our institution and in our experience, office-hysteroscopic placement of the Essure device is a feasible and effective approach for permanent sterilization.

Office hysteroscopic sterilization compared with laparoscopic sterilization: a critical cost analysis.

STUDY OBJECTIVE: To evaluate the actual cost difference in performing Essure hysteroscopic sterilization in the office compared with ambulatory surgery using laparoscopic sterilization in the operating room. DESIGN: Cost-comparison analysis (Canadian Task Force classification III). SETTING: University hospital and affiliated outpatient office. INTERVENTIONS: Hysteroscopic placement of Essure device in an office setting and laparoscopic tubal ligation for permanent sterilization. MEASUREMENTS AND MAIN RESULTS: The various costs associated with the two procedures at our institution were compiled, and a direct cost comparison was made. We used actual institutional costs of the procedures, not billing or reimbursement. We found laparoscopic tubal ligations to cost 3449 dollars compared with hysteroscopic placement of the Essure device that costs 1374 dollars yielding a 2075 dollars difference between the procedures. CONCLUSION: In our institution and in our experience, office-hysteroscopic placement of the Essure device is a more cost-effective method than laparoscopic tubal ligation.
