Endometrial ablation with the NovaSure system in Iran

Re-intervention and patient satisfaction rates following office radiofrequency endometrial ablation: a comparative retrospective study of 408 cases

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.

Radiofrequency endometrial ablation for treating heavy menstrual bleeding in women with chronic renal failure

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.

Women's satisfaction and symptoms following NovaSure endometrial ablation: a postal questionnaire survey in Lothian, Scotland

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.

Curative effects of two new endometrial ablation procedures using radiofrequency thermocoagulation for the treatment of severe abnormal uterine bleeding

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.
