Microablative Fractional CO 2 Laser Improves Dyspareunia Related to Vulvovaginal Atrophy: A Pilot Study

Multifaceted Impact of CO2 Laser Therapy on Genitourinary Syndrome of Menopause, Vulvovaginal Atrophy and Sexual Function

Genitourinary syndrome of menopause (GSM) encompasses a range of distressing symptoms in the vulvovaginal and/or bladder-urethral regions related to menopause changes, negatively influencing woman's quality of life and sexual activity. Fractional micro-ablative CO2 laser therapy has shown the potential to reinstate the vaginal epithelium to a condition akin to the premenopausal state, thereby ameliorating the subjective symptoms associated with GSM. We conducted a prospective, pilot study in 73 sexually active postmenopausal women treated with CO2 laser for their GSM symptoms, while assessing Vaginal Health Index Score (VHIS) and sexual function through the Female Sexual Function Index (FSFI) Questionnaire. The laser treatment resulted in a decrease in VHIS and patient-reported vulvovaginal atrophy (VVA) symptoms, with a significantly lower prevalence of vaginal itching, dryness, and burning (p < 0.001), as well as dyspareunia (p = 0.002). The occurrence of urinary incontinence, urgency, and vaginal heaviness significantly reduced, with an improvement in the staging of cystocele, either to Stage 1 or complete resolution (p < 0.001). FSFI total and domain scores were significantly higher after the treatment, indicating better sexual function, with a post-treatment score median of 25 (p < 0.001). Therefore, using a three-cycle fractional CO2 laser was an effective choice for reducing urogenital discomfort related to GSM in postmenopausal women.

Understanding the Benefits of CO2 Laser Treatment for Vulvovaginal Atrophy

Background and Objectives: Postmenopausal vaginal discomfort is often attributed to vulvovaginal atrophy (VVA). Women with VVA experience symptoms such as vaginal dryness, itching, burning, irritation, and dyspareunia. Materials and Methods: This pilot study was conducted to assess the effects of a micro-ablative fractional CO2 laser on the clinical symptoms of VVA, as well as concordant sexual function. The severity of VVA symptoms was evaluated by a visual analogue scale (VAS), while the condition of the vaginal mucosa was evaluated using the Vaginal Health Index Score (VHSI). Sexual function was evaluated using the Female Sexual Function Index (FSFI) Questionnaire. Results: Our cohort included 84 sexually active postmenopausal women with bothersome VVA, leading to sexual health complaints. The mean age of the participants in our study was 55.2 ± 5.4 years, with an average postmenopausal period of 6 ± 4.8 years. The age of our patients and the length of their postmenopausal period exhibited a significant negative correlation with VHSI scores, while a longer postmenopausal period was associated with increased severity of vaginal dryness and dyspareunia. Baseline VHSI values showed that 65% of patients had atrophic vaginitis with pronounced VVA symptoms (70.2% experienced vaginal itching, 73.8% reported vaginal burning, 95.3% had vaginal dryness, and 86.1% suffered from dyspareunia). Lower VHSI values significantly correlated with lower FSFI scores, while more severe VVA symptoms scores correlated with lower FSFI scores. VVA symptoms were significantly less severe after treatment. VHIS regained high non-atrophic values in 98.8% of patients post-treatment (p < 0.001). FSFI total and domain scores were significantly higher after treatment (p < 0.001). Conclusions: Our study revealed that fractional CO2 laser is a useful treatment option to alleviate VVA symptoms and improve vaginal health and sexual functioning in postmenopausal women.

Vaginal laser therapy for GSM/VVA: where we stand now - a review by the EUGA Working Group on Laser

Vulvovaginal atrophy (VVA) is a chronic progressive condition that involves the genital and lower urinary tracts, related to the decrease of serum estrogenic levels when menopause occurs. The definition of genitourinary syndrome of menopause (GSM) is a medically more accurate, all-encompassing and publicly acceptable term than VVA. Due to the chronic progressive trend of GSM, symptoms tend to reappear after the cessation of therapy, and frequently long-term treatment is required. First-line therapies include vulvar and vaginal lubricant or moisturizers, and, in the case of failure, low-dose vaginal estrogens are the preferred pharmacological therapy. Populations of patients, such as breast cancer (BC) survivors, are affected by iatrogenic GSM symptoms with concerns about the use of hormonal therapies. The non-ablative erbium:YAG laser and the fractional microablative CO2 vaginal laser are the two main lasers evaluated for GSM treatment. The aim of this comprehensive review is to report the efficacy and safety of Er:YAG and CO2 vaginal lasers for GSM treatment. Vaginal laser therapy has been demonstrated to be effective in restoring vaginal health, improving VVA symptoms and sexual function. The data suggest that both Er:YAG and CO2 vaginal lasers are safe energy-based therapeutic options for management of VVA and/or GSM symptoms in postmenopausal women and BC survivors.

The efficacy of CO2 laser in the treatment of genitourinary syndrome of menopause: a systematic review and meta-analysis of randomized controlled trials

CO₂ laser has been proposed as a treatment strategy for genitourinary syndrome of menopause (GSM). In order to assess its efficacy for treating GSM, we conducted a systematic review and meta-analysis. To identify the current state of randomized controlled trials on CO₂ laser therapy for GSM, a literature review was conducted. We systematically searched the following databases: PUBMED, EMBASE and the Cochrane Controlled Trials Register. In addition, a review of the references in the retrieved studies was carried out. Of 562 identified studies, 9 were eligible and were included in our analysis, involving 523 patients in total. Based on our analysis, CO₂ laser has no statistical difference compared with estrogen in VHI (p = 0.87), FSFI total score (p = 0.19), FSFI-Arousal (p = 0.11), FSFI-Desire (p = 0.72), FSFI-Orgasm (p = 0.45) and FSFI-Satisfaction (p = 0.08). The meta-analysis also showed that CO₂ laser significantly improved FSFI-Lubrication scores compared with estrogen therapy (p = 0.0004). Furthermore, compared with the sham group, CO₂ laser group had statistically improved VHI scores (p = 0.003) and FSFI scores (p < 0.00001). CO₂ laser therapy may be an effective alternative to estrogen therapy for GSM both in cases where estrogen is not applicable because of comorbidities and in cases in which women do not desire to take estrogen.

Efficacy of Fractional CO2 Laser Treatment for Genitourinary Syndrome of Menopause in Short-Term Evaluation-Preliminary Study

The postmenopausal state covers 40% of modern women's lives and 50-70% of postmenopausal women report GSM symptoms such as vaginal dryness, itching, frequent inflammations, lack of elasticity, or dyspareunia. Consequently, a safe and effective method of treatment is crucial. In a group of 125 patients, a prospective observational study was performed. The aim was to evaluate the clinical effectiveness of fractional CO₂ laser in the treatment of GSM symptoms using a protocol of three procedures in 6-week intervals. The vaginal pH, VHIS, VMI, FSFI, and treatment satisfaction questionnaire were used. The fractional CO₂ laser treatment was effective in improving all the objective forms of evaluation: vaginal pH (from 5.61 ± 0.50 at the baseline up to 4.69 ± 0.21 in the 6-week follow-up after the third procedure); VHIS (12.02 ± 1.89 at the baseline vs. 21.50 ± 1.76); VMI (21.5 ± 5.66 vs. 48.4 ± 4.46). Similar results were obtained for FSFI: 12.79 ± 5.351 vs. 24.39 ± 2.733, where 79.77% of patients were highly satisfied. Fractional CO₂ laser therapy increases the quality of life by having a beneficial effect on the sexual function of women with GSM symptoms. This effect is obtained by restoring the correct structure and proportions of the cellular composition of the vaginal epithelium. This positive effect was confirmed by both objective and subjective forms of evaluating GSM symptom severity.

Fractional Carbon Dioxide Laser Improves Vaginal Laxity via Remodeling of Vaginal Tissues in Asian Women

Background: Vaginal laxity (VL) is characterized by the relaxing of the vaginal wall that affects the quality of life and sexual function of patients. The current management of VL such as Kegel exercises and topical or systemic hormonal replacement results in unsatisfactory outcomes; thus, novel modalities are needed to improve the efficacy. Vaginal fractional carbon dioxide (CO2) laser treatment has shown growing applications for the treatment of VL, but results show nonconformities due to the lack of objective evaluations. In this study, we aimed to validate the clinical efficacy and biophysical benefits of fractional CO2 laser treatment for VL patients with the incorporation of objective approaches. Methods: This is a descriptive study without controls. A total of 29 patients were enrolled and treated with two sessions of FemTouch vaginal fractional CO2 laser, with a one-month interval between sessions. Both subjective and objective measurements, including female sexual function index (FSFI), vaginal health index score (VHIS), vaginal tactile imaging (VTI), and histology were used to validate the clinical efficacy and biophysical benefits after treatment. Results: The overall FSFI scores and VHIS scores after the first and second treatment sessions were significantly higher than the baseline scores (p < 0.01, n = 29). VTI measurements showed a significant increase in maximal pressure resistance (kPa) of both the anterior and posterior vaginal walls at a 10−12-month post-treatment visit compared with pre-treatment controls (p < 0.001; n = 16). Histological examination showed that laser treatment led to increases in the thickness of the stratified squamous epithelium layer and density of connective tissues in the lamina propria. Conclusions: Fractional CO2 vaginal laser treatment can improve both vaginal health and sexual function and restore vaginal biomechanical properties by increasing vaginal tissue tightening and improving vaginal tissue integrity in Asian women. Our data support that fractional CO2 vaginal laser is a valid treatment modality for VL.

CO2-Laser therapy and Genitourinary Syndrome of Menopause: A Systematic Review and Meta-Analysis

BACKGROUND

Genitourinary syndrome of menopause (GSM) is a widespread condition with a great impact on quality of life and self-image.

AIM

We aimed to systematically review the current literature on CO2-Laser therapy efficacy for the treatment of GSM.

METHODS

MEDLINE and Embase databases were systematically queried in December 2020 Studies included women with a diagnosis of Vulvo-Vaginal Atrophy (VVA) or GSM without an history of gynaecological and/or breast cancer, pelvic organ prolapse staged higher than 2, pelvic radiotherapy or Sjogren's Syndrome. The quality of the evidence was assessed with the Cochrane risk of bias tool. This study is registered on PROSPERO, number CRD42021238121.

OUTCOMES

Effects of CO2-Laser therapy on GSM symptoms assessed through subjective or objective efficacy measurement methods.

RESULTS

A total of 803 articles were identified. Of these, 25 studies were included in this review for a total of 1,152 patients. All studies showed a significant reduction in VVA and/or GSM symptoms (dryness, dyspareunia, itching, burning, dysuria). The pooled mean differences for the symptoms were: dryness -5.15 (95% CI:-5.72,-4.58; P < .001; I2:62%; n = 296), dyspareunia -5.27 (95% CI:-5.93,-4.62; P < .001; I2:68%; n = 296), itching -2.75 (95% CI:-4.0,-1.51; P < .001; I2:93%; n = 281), burning -2.66 (95% CI:-3.75, -1.57; P < .001; I2:86%; n = 296) and dysuria -2.14 (95% CI:-3.41,-0.87; P < .001; I2:95%; n = 281). FSFI, WHIS and VMV scores also improved significantly. The pooled mean differences for these scores were: FSFI 10.8 (95% CI:8.41,13.37; P < .001; I2:84%; n = 273), WHIS 8.29 (95% CI:6.16,10.42; P < .001; I2:95%; n = 262) and VMV 30.4 (95% CI:22.38,38.55; P < .001; I2:24%; n = 68). CO2-Laser application showed a beneficial safety profile and no major adverse events were reported.

CLINICAL IMPLICATIONS

Vaginal laser treatment resulted in both a statistically and clinically significant improvement in GSM symptoms. FSFI improved significantly in all 8 included studies but it reached a clinically relevant level only in 2 of them.

STRENGTHS & LIMITATIONS

The strength of the current meta-analysis is the comprehensive literature search. We reported data from a high number of patients (1,152) and high number of laser applications (more than 3,800). The main limitations are related to the high heterogeneity of the included studies investigating laser effects. Moreover, most of them are single center and nonrandomized studies.

CONCLUSION

The data suggest that CO2-Laser is a safe energy-based therapeutic option for the management of VVA and/or GSM symptoms in postmenopausal women; however, the quality of the body of evidence is "very low" or "low".

Effects of Fractional CO2 Laser Treatment on Patients Affected by Vulvar Lichen Sclerosus: A Prospective Study

Background: Fractional carbon dioxide (CO₂) lasers are today considered the most effective and efficient treatment for many vulvovaginal disorders, providing mini-invasive procedures without side effects. Previous studies demonstrated the efficacy of fractional CO₂ lasers in vulvar lichen sclerosus (VLS), a chronic skin disorder characterized by itching and painful lesions. Complications include pain, sexual and/or urinary dysfunction, with a negative quality of life, and an increased risk of squamous cell carcinoma. A definitive VLS treatment is still lacking. Objectives: This is a prospective, single-center study aimed at evaluating the effect of fractional microablative CO₂ laser treatment on women affected by VLS. Materials and methods: Patients with histologically confirmed VLS underwent three fractional microablative CO₂ laser treatments, 4 weeks apart, on the genital affected areas. Clinical and VLS-related symptoms, side effects, and patient satisfaction index were assessed and recorded for all the patients using the visual analog scale (VAS). Results: Data from a total of 70 patients were included, paired at different time points and analyzed. VLS-related symptoms and other relevant parameters (pH, vaginal introitus discomfort, dyspareunia, vaginal dryness, itching, and burning) showed a statistically significant improvement (p < 0.001) after the first laser treatment and kept improving after second and third sessions. According to VAS, the two most common symptoms, vaginal introitus discomfort and dyspareunia, went from (mean ± standard deviation) 8.2 ± 2.3 and 8.3 ± 2.2, respectively, at baseline, to 3.6 ± 2.6 and 3.8 ± 2.6, respectively, 1 month after the last treatment. Vaginal dryness, itching, and burning were significantly improved as well. Most patients declared to be very satisfied with the results of the treatment. A total of 62.8% of the women expressed a satisfaction score ≥8 on a scale from 0 to 10. Conclusions: Fractional microablative CO₂ laser treatment seems to be safe and effective to treat VLS and improve VLS-related symptoms.

Use of a vaginal CO2 laser for the management of genitourinary syndrome of menopause in gynecological cancer survivors: a systematic review

Genitourinary syndrome of menopause (GSM) may arise from the hypoestrogenism caused by ovarian function destruction following gynecological cancer treatments. GSM may also be present in menopausal women and its symptoms might be exacerbated by cancer treatments. Historically, patients with hormone-dependent gynecological cancer and physicians have been less comfortable using vaginal estrogen due to fear of recurrence. CO₂ vaginal laser therapies have demonstrated efficacy as a non-hormonal alternative for GSM treatment in healthy menopausal patients. The objective of this study was to evaluate the data on the effect of a CO₂ vaginal laser for the management of GSM in gynecological cancer patients. Databases searched included MEDLINE, Embase, PubMed, Cochrane and Google Scholar. Selected studies assessed use of a CO₂ vaginal laser in gynecological cancer patients with GSM. A total of 269 studies were retrieved. Four studies met the inclusion criteria. Each study followed a different type of CO₂ vaginal laser protocol for the management of GSM in gynecological cancer patients. There are no randomized controlled trials that assess the use of a CO₂ vaginal laser in gynecologic cancer patients. The number of published gynecological cancer patients treated with a CO₂ laser for the management of GSM is extremely limited (N < 100). There is a lack of literature on the impact and safety of vaginal CO₂ laser use to manage GSM in gynecologic cancer patients.

Effect of Fractional Carbon Dioxide Laser vs Sham Treatment on Symptom Severity in Women With Postmenopausal Vaginal Symptoms: A Randomized Clinical Trial

IMPORTANCE

Postmenopausal vaginal symptoms are common and frequently detrimental to a woman's quality of life. Fractional carbon dioxide vaginal laser is increasingly offered as a treatment, but the efficacy remains unproven.

OBJECTIVE

To determine the efficacy of fractional carbon dioxide laser for treatment of vaginal symptoms associated with menopause.

DESIGN, SETTING, AND PARTICIPANTS

A double-blind, randomized, sham-controlled trial with 12-month follow-up was undertaken at a single tertiary referral hospital in Sydney, Australia. Enrollment commenced on September 19, 2016, with final follow-up on June 30, 2020. Participants were postmenopausal women with vaginal symptoms substantive enough to seek medical treatment. Of 232 participants approached, 85 were randomized.

INTERVENTIONS

Three treatments using a fractional microablative carbon dioxide laser system performed 4 to 8 weeks apart, with 43 women randomized to the laser group and 42 to the sham group.

MAIN OUTCOMES AND MEASURES

The co-primary outcomes were symptom severity assessed using a visual analog scale (VAS; range, 0-100; 0 indicates no symptoms and 100 indicates the most severe symptoms) and the Vulvovaginal Symptom Questionnaire (VSQ; range, 0-20; 0 indicates no symptoms and 20 indicates the most severe symptoms) at 12 months. The minimal clinically important difference was specified as a 50% decrease in both VAS and VSQ severity scores. There were 5 prespecified secondary outcomes, including quality of life (range, 0-100; higher scores indicate better quality of life), the Vaginal Health Index Score (range, 5-25; higher scores indicate better health), and vaginal histology (premenopausal or postmenopausal status).

RESULTS

Of 85 randomized participants (mean [SD] age, 57 [8] years), 78 (91.7%) completed the 12-month follow-up. From baseline to 12 months, there was no significant difference between the carbon dioxide laser group and the sham group in change in symptom severity (VAS score for overall vaginal symptoms: -17.2 vs -26.6; difference, 9.4 [95% CI, -28.6 to 47.5]; VAS score for the most severe symptom: -24.5 vs -20.4; difference -4.1 [95% CI, -32.5 to 24.3]; VSQ score: -3.1 vs -1.6; difference, -1.5 [95% CI, -5.9 to 3.0]). There were no significant differences between the laser and sham group in the mean quality of life score (6.3 vs 1.4; difference, 4.8 [95% CI, -3.9 to 13.5]) and Vaginal Health Index Score (0.9 vs 1.3; difference, -0.4 [95% CI, -4.3 to 3.6]) or in histological comparisons between laser and sham treatment groups. There were 16 adverse events in the laser group and 17 in the sham group, including vaginal pain/discomfort (44% vs 68%), spotting, discharge, and lower urinary tract symptoms. No severe adverse events were reported in either group.

CONCLUSIONS AND RELEVANCE

Among women with postmenopausal vaginal symptoms, treatment with fractional carbon dioxide laser vs sham treatment did not significantly improve vaginal symptoms after 12 months.

Efficacy of CO2 laser treatment in postmenopausal women with vulvovaginal atrophy: A meta-analysis

OBJECTIVE

To explore the efficacy of CO₂  laser treatment in postmenopausal women with vulvovaginal atrophy.

METHOD

PubMed, Embase, Cochrane Library and Web of Science were searched to June 9, 2020. Prospective studies on the efficacy of CO₂  laser treatment were included. Two researchers independently reviewed articles and extracted data. Heterogeneity test was conducted for each outcome indicator. Sensitivity analysis was performed in all models.

RESULTS

Twelve articles including 459 participants were enrolled. Compared with baseline, vaginal health indeices (VHIs) were significantly higher at the 1-, 3-, 6-, and 12-month follow ups (P < 0.001). For VVA severity, the visual analog scale scores for vaginal dryness at 1-, 3-, 6-, and 12-month follow-ups (P < 0.050), vaginal burning, itching, and dysuria at 1-month follow up (P < 0.001), and dyspareunia at 1-, 3-, 6-, and 12-month follow-ups (P < 0.001) were all significantly lower. For FSFI, total scores at 1-, 3-, 6-, and 12-month follow ups (P < 0.001), and the scores in desire, arousal, lubrication, orgasm, satisfaction, and pain at 1-month follow up (P < 0.050) were all significantly higher. For quality of life, the PCS12 and MCS12 scores were all significantly higher (P < 0.050) at the 1-month follow up.

CONCLUSION

CO₂  laser treatment may be effective for postmenopausal women with VVA symptoms in improving quality of life and sexual function.

Evaluation of the effect of multipoint intra-mucosal vaginal injection of a specific cross-linked hyaluronic acid for vulvovaginal atrophy: a prospective bi-centric pilot study

BACKGROUND

Vulvo-vaginal atrophy (VVA) is one of the common consequences of estrogen deficiency especially after the menopause. Several studies have assessed the effects of Hyaluronic acid (HA) on physical and sexual symptoms associated with VVA with promising results. However, most of these studies have focused on subjective assessment of symptom response to topically administered preparations. Nonetheless, HA is an endogenous molecule and it is logical that its effects are best realized if injected in the superficial epithelial layers. Desirial® is the first crosslinked HA that is administered by injection in the vaginal mucosa. The aim of this study was to explore the effect of multipoint vaginal intra-mucosal injections of specific cross-linked hyaluronic acid (DESIRIAL®, Laboratoires VIVACY) on several clinical and patient reported core outcomes.

METHODS

A cohort bi-centric pilot study. The chosen outcomes included change in vaginal mucosa thickness, biological markers for collagen formation, vaginal flora, vaginal pH, vaginal health index, vulvo-vaginal atrophy symptoms and sexual function 8 weeks post Desirial® injection. Patients' satisfaction was also assessed using the patient global impression of improvement (PGI-I) scale.

RESULTS

A total of 20 participants were recruited between 19/06/2017 and 05/07/2018. At the end of the study, there was no difference in the median total thickness of the vaginal mucosa or in procollagen I, III or Ki67 fluorescence. However, there was a statistically significant increase in COL1A1 and COL3A1 gene expression (p = 0.0002 and p = 0.0010 respectively). There was also a significant reduction in reported dyspareunia, vaginal dryness, vulvar pruritus, vaginal chafing and significant improvement in all female sexual function index dimensions. Based on PGI-I, 19 patients (95%) reported varying degrees of improvement where, 4 (20%) felt slightly better; 7 (35%) better and 8 (40%) much better.

CONCLUSIONS

Multi-point vaginal intra-mucosal injections, of Desirial® (a crosslinked HA) was significantly associated with the expression of CoL1A1 and CoL3A1 suggesting stimulation of collagen formation. Furthermore, there was a significant reduction in VVA symptomatology and a significant improvement in patient satisfaction and sexual function scores. However, there was no demonstrable change in the total vaginal mucosal thickness. Study registration ID-RCB: 2016-A00124-47, Protocol code number: LOCAL/2016/PM-001.

Carbon Dioxide Laser Vulvovaginal Rejuvenation: A Systematic Review

Genitourinary syndrome of menopause (GSM) causes significant symptomatic aggravation that affects the quality of life (QoL). Vulvovaginal atrophy (VVA), the hallmark of GSM, is managed with topical non-hormonal therapy, including moisturizers and lubricants, and topical estrogen application. Patients not responding/being unsatisfied with previous local estrogen therapies are candidates for a noninvasive modality. Carbon dioxide (CO2) laser therapy, especially the fractionated type (FrCO2), has drawn considerable attention over the past two decades as a non-invasive treatment for GSM. This systematic review describes the accumulated evidence from 40 FrCO2 laser studies (3466 participants) in GSM/VVA. MEDLINE, Scopus and Cochrane databases were searched through April 2021. We analyze the effects of FrCO2 laser therapy on symptoms, sexual function, and QoL of patients with GSM/VVA. As shown in this review, FrCO2 laser therapy for GSM shows good efficacy and safety. This modality has the potential to advance female sexual wellness. Patient satisfaction was high in the studies included in this systematic review. However, there is a lack of level I evidence, and more randomized sham-controlled trials are required. Furthermore, several clinical questions, such as the number of sessions required that determine cost-effectiveness, should be addressed. Also, whether FrCO2 laser therapy may exert a synergistic effect with systemic and/or local hormonal/non-hormonal treatments, energy-based devices, and other modalities to treat GMS requires further investigation. Lastly, studies are required to compare FrCO2 laser therapy with other energy-based devices such as erbium:YAG laser and radiofrequency.

Non-invasive treatment of vulvovaginal atrophy in menopause with CO2 laser

Genitourinary syndrome of menopause (GSM) may affect up to 90% of menopausal women, including vulvovaginal atrophy (VVA), burning, pain, bleeding, irritation, dyspareunia, anorgasmia, and urinary symptoms. Vaginal symptoms from lack of estrogens can have a significant impact on the sexual health and quality of life (QoL) in as many as 50% of postmenopausal women. Several therapeutic alternatives, both hormonal and non- hormonal, have been proposed. Microablative CO<inf>2</inf> laser is one of the three non-surgical energy-based therapies, with Erbium:YAG laser and temperature-controlled radiofrequency (RF). Microablative CO<inf>2</inf> laser induces morphological changes in vaginal tissues and results of several clinical trials suggest that this type of laser improves symptoms of GSM. Moreover, this treatment seems to be safe. Given the increasingly widespread use of laser CO<inf>2</inf> as a non-hormonal alternative treatment for GSM, the authors reviewed the current published literature evaluating this therapy, to compare efficacy and safety of different protocols.

Microablative Fractional CO2 Laser for Vulvovaginal Atrophy in Women With a History of Breast Cancer: A Pilot Study at 4-week Follow-up

BACKGROUND

Breast cancer (BC) is the most common female cancer worldwide. Menopausal symptoms are a well-known side effect in women with BC and have a significant negative impact on quality of life (QoL) and sexuality. Nowadays, hormonal replacement therapy and local estrogens are the most common prescriptions to treat vulvovaginal (VVA) symptoms. However, in women with a history of BC, proper therapy for such conditions remains an often inadequately addressed clinical problem. A treatment with microablative fractional CO₂ laser (MLT) can produce a remodeling of the vaginal connective tissue without causing damage to the surrounding tissue. The aim of this pilot study is to assess the efficacy and safety of MLT for treating VVA symptoms in women with a history of BC at 20-week follow-up since the first laser treatment.

PATIENTS AND METHODS

Women with BC and VVA symptoms were enrolled in the study and treated with 5 laser applications (one every 4 weeks). The rate of satisfied patients at 20 weeks of follow-up was evaluated with a 5-point Likert scale. Changes of the Vaginal Health Index (VHI) after treatment was compared with baseline. Effects of the laser treatment on VVA symptoms was measured using a 10-cm visual analog scale (VAS). Changes in overall QoL were assessed with a generic QoL questionnaire: the Short Form 12 (SF-12) that we analyzed considering its physical (PCS12) and mental (MCS12) domains. Sexual function was evaluated by the Female Sexual Function Index (FSFI).

RESULTS

In this prospective cohort study, we enrolled 40 women with a history of BC and who currently were or (Group 2) who had been (Group 1) on treatment with endocrine therapy for their condition. Six (15.0%) women were very satisfied, 25 (62.5%) were satisfied, 6 (15.0%) were uncertain, and 3 (7.5%) were dissatisfied with the MLT. VVA symptoms and VHI improved significantly at 20 weeks from baseline (P < .05) with no differences between the 2 groups (P > .05). In terms of QoL measured by the SF-12, the PCS12 and the MCS12 significantly improved at the 20-week follow-up. A significant improvement in total FSFI and in all domains was reported in both study groups (P < .05) with no differences between groups (P > .05).

CONCLUSION

MLT was safe and effective in treating VVA symptoms in women with a history of BC, irrespective of being previously or currently on endocrine therapies.

Physical methods for the treatment of genitourinary syndrome of menopause: A systematic review

BACKGROUND

Genitourinary syndrome of menopause (GSM) negatively affects sexual function and quality of life. Techniques like laser and radiofrequency are being used to manage GSM, particularly in women with contraindications for hormone therapy.

OBJECTIVES

To verify whether the physical methods of laser and radiofrequency can be recommended as safe and effective options for the treatment of GSM/urinary urgency or incontinence in pre- and postmenopausal women.

SEARCH STRATEGY

Databases were comprehensively searched using combinations of the following keywords in any language: "postmenopause"; "genitourinary syndrome of menopause"; "vaginal atrophy"; "radiofrequency"; and "laser."

SELECTION CRITERIA

Full articles of case-control, cross-sectional, cohort, randomized clinical trials, and quasi-randomized or controlled clinical trials were included.

DATA COLLECTION AND ANALYSIS

All authors independently evaluated the design of the studies for quality of reporting, risk of bias, and quality of evidence.

MAIN RESULTS

Of the included 49 studies, 37 were on the CO₂ laser, 10 on the Erbium laser, and two on radiofrequency.

CONCLUSIONS

Laser and radiofrequency therapy could be promising and safe therapeutic options for GSM/urinary incontinence. However, the study findings cannot be generalized until new randomized clinical trials are performed that confirm the strength of the evidence. This review has been registered with PROSPERO: CRD42020141913.

Does the Time of Onset of Urinary Symptoms Affect Microablative Fractional CO2 Laser Efficacy in Postmenopausal Women?

BACKGROUND AND OBJECTIVE

To evaluate the safety and efficacy of transvaginal fractional microablative CO₂ laser therapy (MLT) on urinary symptoms in postmenopausal women with genitourinary syndrome of menopause (GSM) in relation to the timing of their onset; if prior to or after menopause. Secondary, the efficacy of MLT on vulvovaginal atrophy (VVA)-related symptoms.

STUDY DESIGN/MATERIALS AND METHODS

This is a retrospective analysis of prospectively collected data. Postmenopausal women affected by at least one urinary symptom (urinary frequency, urgency incontinence, stress urinary incontinence) and VVA symptom each (dryness, dyspareunia, itching, burning) were enrolled. Our population was divided into two groups in relation to the onset of urinary symptoms, prior to or after menopause. Women were treated with three CO₂ MLT laser sessions, administered at a 4-week interval. For urinary symptoms evaluation, we used the following disease-specific questionnaires previously validated in Italy: the Urogenital Distress Inventory score (UDI-6) and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). For each single VVA symptom, we assessed patient's severity perception with a 10-point visual analog scale. Time points of the study were at entry (T0) and at 16 weeks since the first treatment (T1). Collected data were analyzed with the Pearson χ ² test for categorical variables and the Wilcoxon rank-sum test (for non-normally distributed data), and statistical significance was defined with a P-value <0.05.

RESULTS

Sixty-one women were enrolled in this study. Overall, at T1 MLT brought to a significant improvement in urinary symptoms (P < 0.05) in women with urinary symptoms started after the menopause (Group B), contrary to the ones with urinary symptoms started before the menopause (Group A). Specifically, urinary frequency significantly improved only in Group B (P < 0.05), while urgency incontinence, significantly reduced in both groups (P < 0.05). Stress urinary incontinence did not significantly improve in both groups (P > 0.05). Secondary, all VVA symptoms showed a statistically significant improvement (P < 0.05) at 16 weeks from baseline; no differences were registered between groups. No adverse events were recorded.

CONCLUSION

This study confirms the safety and efficacy of CO₂ MLT for GSM symptoms. When urinary symptoms are considered, it seems that MLT might have a higher efficacy when symptoms started after menopause, in particular when they are part of the OAB syndrome. Lasers Surg. Med. © 2021 Wiley Periodicals LLC.

A Systematic Review of Nonsurgical Vulvovaginal Restoration Devices: An Evidence-Based Examination of Safety and Efficacy

BACKGROUND

The efficacy and safety of vulvovaginal restoration devices were called into question in a U.S. Food and Drug Administration statement on July 30, 2018, claiming that women are being harmed by laser and other energy-based devices. The goal of this systematic literature review was to assess existing data, determine gaps in evidence, and propose opportunities for continued investigation pertaining to laser and energy-based vaginal restoration techniques.

METHODS

A review of literature using PubMed, Cochrane Library databases, Embase, MEDLINE, and the Cumulative Index to Nursing and Allied Health Literature was conducted on January 9, 2019, and articles up to this point were considered. For inclusion, studies had to be available or translated in English and relate to clinical medicine, direct patient care, and nonsurgical energy-based vulvovaginal procedures.

RESULTS

The authors found five level I studies, 19 level II studies, four level III studies, and 46 level IV studies that used 15 different devices. Various degrees of improvement of symptoms were reported in all studies. Adverse events/side effects were noted in two of the 13 radiofrequency device studies, 15 of the 23 erbium:yttrium-aluminum-garnet device studies, and 17 of the 37 carbon dioxide device studies. The majority of adverse events were considered mild.

CONCLUSIONS

The majority of studies resulted in mild to no adverse side effects. However, there is a large gap in level I evidence. As a result, the authors emphasize the necessity of supplemental data surrounding this subject and suggest that additional randomized sham-controlled studies be conducted to further investigate vulvovaginal restoration devices in an effort to address women's health issues.

Vaginal laser treatment of genitourinary syndrome of menopause: does the evidence support the FDA safety communication?

IMPORTANCE

Genitourinary syndrome of menopause (GSM) is a chronic, progressive condition frequently manifesting as vaginal dryness and pain with intercourse. Survey data indicate this is a highly prevalent, likely underreported, condition that profoundly affects quality of life for millions of women. Vaginal lasers demonstrate promise as an effective, nonhormone therapeutic alternative for GSM; however, the risks associated with them may have been overstated.

OBJECTIVE

Despite reports of improved sexual and vaginal comfort without serious safety concerns, the Food and Drug Administration (FDA) issued a 2018 safety communication warning against it. We conducted a systematic literature review and surveyed both the FDA Manufacturer and User Facility Device Experience (MAUDE) and Bloomberg Law Databases to evaluate risks associated with laser treatment for GSM.

EVIDENCE REVIEW

A systematic literature review identified articles published before September 2019. The MAUDE database was searched by name from 2009 to 2019 for safety claims for 24 vaginal laser devices. The Bloomberg Law database was searched for product liability claims against any vaginal laser device manufacturer before July 2019.

FINDINGS

Literature review revealed 3 publications detailing 29 presumptive laser-associated complications, only 5 of which (17.2%) reported worsening symptoms after treatment. The MAUDE database contained 120 complaints; only 30 (25%) detailed potential adverse patient events, most frequently pain (n = 12) and burning (n = 10). The Bloomberg law database contained no claims asserting harm from device use.

CONCLUSIONS AND RELEVANCE

Lacking strong evidence indicating significant patient risk for vaginal laser treatment of GSM, the FDA safety communication appears unsubstantiated and implies gender bias. Identified complications suggest most reported "adverse events" represent lack of treatment effect. The well-documented benefits and low risk of adverse event suggest laser therapy for GSM is reasonable with appropriate pretreatment counseling. Additional randomized, well-controlled clinical trials are needed to further elucidate both the safety and efficacy of this nonhormone therapy.

Rationale and design for fractional microablative CO2 laser versus photothermal non-ablative erbium:YAG laser for the management of genitourinary syndrome of menopause: a non-inferiority, single-blind randomized controlled trial

Genitourinary syndrome of menopause (GSM) is a common condition affecting up to 50% of postmenopausal women and up to 70% of postmenopausal breast cancer survivors. GSM is a chronic condition with a significant impact on sexual health and quality of life. The mainstay of treatment has been with symptomatic relief using topical emollients or lubricants. Second-line treatment is with topical vaginal estrogens to restore the physiology of the vaginal epithelium. For some, the latter is not suitable or acceptable. Newer treatments with ospemifene and vaginal lasers have now been introduced. The two main types of laser currently used for the treatment of GSM are the fractional microablative CO₂ laser and the non-ablative photothermal erbium:YAG laser. We present a study protocol for a multicenter, prospective, non-inferiority, single-blinded, randomized controlled trial comparing the fractional microablative CO₂ laser versus the photothermal non-ablative erbium:YAG laser for the management of GSM. We will recruit 88 postmenopausal women across two sites who will be randomized to one of the two laser groups. Participants will all have GSM symptoms and a Vaginal Health Index Score < 15. All participants will receive an active treatment. Each participant will receive three applications of vaginal laser 1 month apart and will be followed up at 1 month, 6 months, and 12 months. Our primary outcomes will look at all changes of GSM symptoms (dryness, dyspareunia, itching, burning, dysuria, frequency, urgency), urinary incontinence (if present), and overall sexual satisfaction. Both subjective and objective means will be used to assess participants. The findings of this trial have the potential to allow clinicians and women suffering from GSM to make an informed decision when opting for a specific laser type. The trial will add to the current growing body of evidence for the safe use of vaginal lasers in GSM as an alternative treatment. We hope this trial will provide robust and long-term data for the safe use of both lasers.

[CO2 LASER for the treatment of vaginal symptoms of genitourinary syndrome of menopause]

Genitourinary syndrome of menopause (GSM) brings together a collection of signs including vaginal dryness, burning sensation and itching discomfort as well as deterioration of sexual health, dysuria, urgenturia and repeated urinary infections and may be responsible for a significant impairment of quality of life in symptomatic postmenopausal women. The management of GSM therefore represents a public health issue. Systemic or local hormonal treatments are frequently offered, as well as non-hormonal treatments. The existence of contraindications to hormonal treatments and the constraints of using local treatments lead us to propose other therapeutic options. CO₂ LASER is now part of the therapeutic arsenal for the treatment of vaginal dryness in the context of GSM. There is a growing interest in this technique, especially for women who have a contraindication to hormonal therapy, as it is a globally effective, long-acting alternative with very little adverse effect. Current evidence suggests that this tool could provide a quality of life benefit to many patients with minimal side effect exposure, if used in the respect of its indications and implementation protocols. However, clinical data based on high-level therapeutic trials remain absolutely essential for this treatment to be validated and recommended by health professionals.

New therapeutic option in genitourinary syndrome of menopause: pilot study using microablative fractional radiofrequency

Objective

To evaluate the clinical response of patients with symptoms of genitourinary syndrome of menopause after application of microablative fractional radiofrequency in the vagina and vaginal introitus.

Methods

Fourteen patients with symptoms of genitourinary syndrome of menopause underwent three applications of microablative fractional radiofrequency with a 30-day interval, using the Wavetronic 6000HF-FRAXX device and a fractional vaginal electrode. The questionnaires World Health Organization Quality of Life (for quality of life evaluation), Female Sexual Function Index and Quality of Life Adapted Questionnaire in the Domain of Sexual Satisfaction (for sexual function and satisfaction evaluation) were administered before and after the applications (30 to 60 days after the last procedure), in addition to the satisfaction questionnaire after procedure.

Results

There was an increase in almost all dimensions on average in quality of life, with statistical significance only in the health domain. There was a significant improvement in the sexual domains in almost all dimensions. All patients stopped using lubricant during intercourse after treatment. In the satisfaction questionnaire after treatment, we observed that the vast majority felt cured or much better (29% and 64%, respectively, total of 92.6%) and were very satisfied or satisfied (43 and 57%, respectively, total of 100%). The only patient who reported little improvement had an 18-year postmenopausal history and was treatment naïve.

Conclusion

Microablative fractional radiofrequency was effective in treating symptoms of vaginal dryness and dyspareunia, and eliminated the use of vaginal lubricant during the period observed. Since this is a pilot study with a small number of patients, further studies are required to corroborate our findings and evaluate the long-term effects of microablative fractional radiofrequency on the vaginal tissue.

The evidence for laser treatments to the vulvo-vagina: Making sure we do not repeat past mistakes

Following menopause, up to 49% of women will experience genitourinary symptoms such as vaginal itching, dryness, dyspareunia and incontinence as a result of oestrogen deficiency. Treatments such as vaginal lubricants and moisturisers only temporarily relieve symptoms, while local oestrogen treatments are often unacceptable or unsafe for many women. Recently, a novel laser treatment has been proposed as a non-invasive, long-term solution to vulvo-vaginal and urinary symptoms. While preliminary histological results have been promising, its therapeutic, clinical effect has yet to be determined. However, despite the scarcity of evidence for its safety and long-term benefit, laser treatments are widely marketed for a range of genitourinary symptoms, with high uptake by both clinicians and women alike. This review aims to examine the evidence for laser treatments to the vulvo-vagina and to evaluate its safety and efficacy. Our results include 17 studies investigating the effect of laser therapy for vulvo-vaginal symptoms, seven for its effects on urinary incontinence and four for histology. These are limited to non-randomised, observational data with small sample sizes between 15 to 175 women and follow-up duration from none to two years. As such, strong evidence for laser efficacy and safety is limited and warrants more robust, placebo-controlled, randomised trials before widespread implementation.

Sexual Function in Women Suffering From Genitourinary Syndrome of Menopause Treated With Fractionated CO2 Laser

INTRODUCTION

Genitourinary syndrome of menopause (GSM) has a significant impact on the trophism of the genital and lower urinary tracts and can considerably impair sexual function. Fractional CO₂ laser has a regenerative effect on vulvovaginal tissue trophism after menopause.

AIM

To review the available literature on the effect of fractional CO₂ laser on the sexual function of postmenopausal women affected by GSM.

METHODS

A database search was carried out using the terms CO₂laser, vaginal atrophy, sexual function, dyspareunia, and genitourinary syndrome of menopause and excluding studies using other types of laser or including breast cancer survivors with vulvovaginal atrophy. For statistical analysis, the estimated overall laser effect was computed (when at least two studies were involved) and data type of generic inverse variance was computed using inverse variance as the statistical method, a random-effects model, and the difference in means as an effect measurement.

MAIN OUTCOME MEASURES

Different methods of evaluating sexual function were reported and studies were grouped and analyzed accordingly. Subjective assessment for dyspareunia was evaluated with a 10-point visual analog scale. Patient-reported outcome for an overall perception of sexual function was evaluated with a Likert scale. The Female Sexual Function Index was used as a condition-specific questionnaire.

RESULTS

Six articles were considered for this review. A total of 273 women (mean age = 57.8 years) were treated with the same protocol in all studies. Compared with baseline, at the end of the treatment, dyspareunia significantly decreased in severity (P < .001), and the patient's perception of overall sexual function showed a statistically significant improvement (P < .001). At the last follow-up visit, the Female Sexual Function Index score for each single domain and overall score was significantly better than at entry (P < .001).

CONCLUSION

Fractional CO₂ laser can improve sexual function in postmenopausal women affected by GSM by restoring a better trophism in the lower genitourinary tract. Salvatore S, Pitsouni E, Del Deo F, et al. Sexual Function in Women Suffering From Genitourinary Syndrome of Menopause Treated With Fractionated CO₂Laser. Sex Med Rev 2017;5:486-494.

Long-term effect of thermoablative fractional CO2 laser treatment as a novel approach to urinary incontinence management in women with genitourinary syndrome of menopause

Introduction and hypothesis

The aim of this study was to evaluate the long-term effect of thermoablative fractional CO₂ laser (TACO2L) as an alternative treatment for early stages of stress urinary incontinence (SUI) in postmenopausal women with genitourinary syndrome of menopause.

Methods

A total of 161 postmenopausal patients (age 53.38 ± 5.1 years, range 45–65 years) with a clinical diagnosis of mild SUI were prospectively enrolled in the study. Patients received one treatment with TACO2L every 30–45 days, each treatment comprising four sessions, followed in all patients by a yearly treatment session at 12, 24 and 36 months. SUI was evaluated using the International Continence Society 1-h pad test and the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) before and after TACO2L treatment.

Results

TACO2L treatment was associated with a significant improvement in ICIQ-UI SF scores and 1-h pad weight test at 12 months (both p < 0.001), 24 months (both p < 0.001) and 36 months (both p < 0.001). Improvements were maintained for up to 36 months without the need for any further intervention. The results were confirmed by significant histological changes related to trophic restoration of the vagina, responsible for extrinsic and intrinsic mechanisms involved in urinary continence.

Conclusions

Our results suggest that TACO2L is an efficient and safe novel treatment strategy in patients with mild SUI. Further investigation to confirm the long-term results presented here is still warranted.

Laser therapy for the restoration of vaginal function

Laser therapy has a therapeutic role in various medical conditions and most recently has gained interest as a non-hormonal treatment for genitourinary syndrome of menopause (GSM) and as a non-invasive option for stress urinary incontinence (SUI). Several therapies are available to alleviate GSM symptoms, including hormonal and non-hormonal products. Both microablative fractional CO₂ laser and the non-ablative vaginal Er:YAG laser (VEL) induce morphological changes in the vaginal tissues, and data from non-randomized clinical trials suggest that laser therapy can alleviate vaginal dryness and dyspareunia. VEL has been reported to improve SUI as well as vaginal prolapse. Although large randomized trials have not been reported, the evidence suggests that VEL can be offered as a safe and efficacious alternative to hormone replacement therapy (HRT) for GSM, as well as a first-line treatment for mild to moderate SUI, before surgical procedures are resorted to. Randomized studies are needed to compare laser treatments with other therapies, as well as to assess the duration of the therapeutic effects and the safety of repeated applications. Research is presently evaluating both an automated robotic probe for VEL treatments and an intraurethral probe for the treatment of severe and type III SUI.

Genitourinary syndrome of menopause and the use of laser therapy

Genitourinary syndrome of menopause is a common condition that left untreated can progress and negatively affect quality of life and sexual function. Laser therapy has a therapeutic role for several gynecologic conditions and most recently has gained interest as a non-hormonal treatment for genitourinary syndrome of menopause (GSM). The laser is well tolerated and may increase thickness of the squamous epithelium and improve vascularity of the vagina. These morphological changes presumably alleviate symptoms of dryness, dyspareunia, and irritation. However, the duration of therapeutic effects and safety of repeated applications at this point is not clear. Further research is needed in the form of controlled studies of the laser and other non-hormonal GSM therapies. The objective of this paper is to review the existing literature describing laser therapy for GSM.
