Abstract

Background: Endometrial ablation is an established uterus-sparing treatment for heavy menstrual bleeding (HMB), but average amenorrhea rates remain around 50%. Ablation limitations and side effects have spurred interest in less invasive alternatives.

Purpose: This review comprehensively surveys emerging endometrial ablation techniques, regenerative and pharmaceutical options, and future directions in HMB management. It provides an updated synthesis of the latest promise and pitfalls in both established and novel therapeutic approaches.

Main body: Global ablation methods have reduced operative risks versus first generation hysteroscopic options, but treatment failures still occur. Innovations like magnetic resonance-guided focused ultrasound ablation, endometrial resection, and temporary hormonal suppression aim to further expand choices, improve outcomes, and avoid permanent ablation. However, comparative effectiveness studies are lacking and optimal patient selection unclear. This review highlights promising areas of research, while delineating limitations and knowledge gaps needing further study.

Conclusion: Continued innovation and investigation of less invasive options may personalize therapy and reduce ablation complications and retreatment rates. But robust evidence on long-term fertility, regeneration, quality of life, and cost-effectiveness is still needed guide best practices in this evolving field.

1.Introduction

Heavy menstrual bleeding (HMB), defined as excessive menstrual blood loss of over 80mL per cycle, is a common gynecological disorder estimated to affect up to 30% of women worldwide. The excessive blood loss and duration of menstruation associated with HMB can have a significant detrimental impact on a woman's physical, social, emotional and material quality of life. Anemia resulting from chronic iron deficiency is a common complication. As women age, the prevalence of HMB tends to increase due to conditions like adenomyosis, fibroids and coagulation disorders [1]. When medical management of HMB fails, endometrial ablation has emerged as an 

effective alternative to hysterectomy. Endometrial ablation is a procedure that destroys the lining of the uterus (endometrium) in order to reduce or stop excessive menstrual bleeding. First generation ablation techniques utilized hysteroscopically-guided destruction of the endometrium by heated fluid, laser or electrosurgery. Global ablation methods were later introduced, which destroy the entire endometrium at once using thermal balloon, radiofrequency electrical energy, cryotherapy or microwave energy without visual guidance [2]. 

While clinical trials have shown endometrial ablation provides significant improvement in HMB and quality of life in most women, limitations exist. Average amenorrhea (cessation of periods) rates are only around 50% and treatment failure or unsatisfactory improvement in bleeding occurs in 15-30% of women. Post-ablation pain, infection, uterine perforation, asherman's syndrome and other complications can also occur. For these reasons, research is ongoing to evaluate new technologies and refine ablation techniques [3]. While endometrial ablation fills an important niche in heavy menstrual bleeding treatment, limitations like suboptimal amenorrhea rates, pain, and treatment failure affecting up to 30% of women underscore the need for continued innovation. This review provides an updated synthesis of emerging ablation techniques, regenerative approaches, and pharmaceutical alternatives. It delineates latest developments, knowledge gaps, and future directions in this evolving field [4].  While endometrial ablation is an established treatment for heavy menstrual bleeding, average amenorrhea rates remain only around 50% and complications prompt re-treatment in 15-30% of women. This underscores the need to survey emerging technologies like focused ultrasound, novel resection devices, and temporary pharmaceutical options that may expand choices, limit side effects, and improve outcomes. By comprehensively evaluating the latest evidence on both conventional and innovative approaches, this review provides updated recommendations to guide optimal integration of traditional techniques with disruptive innovations in this rapidly evolving ablation field.

II. Current endometrial ablation techniques

First generation endometrial ablation techniques utilized direct visualization of the uterine cavity with a hysteroscope to guide destruction of the endometrium [5]. Heated fluid, laser energy or electrosurgery with a rollerball could be directed to the lining. These hysteroscopic methods required additional training, surgical skill and longer operating room time [6]. Global endometrial ablation was later introduced as a second generation approach, allowing the entire endometrium to be treated at once without visually guiding the ablation. Common global ablation modalities include heated liquid-filled balloons, radiofrequency electrical energy, cryoablation probes and microwave devices inserted transcervically into the uterus [7].

Each ablation modality has unique benefits and risks. Heated fluid techniques like the thermal balloon can treat variable uterine shapes and are less dependent on operator skill [8]. Radiofrequency ablation is fast, simple and does not require general anesthesia in the outpatient setting. Cryoablation and microwave energy have the advantages of myocardial ablation devices which selectively destroy the endometrium while sparing deeper myometrium [9]. In clinical studies, global endometrial ablation has equaled or exceeded the amenorrhea rates of hysteroscopic ablation, ranging from 45-75
