Effect of Alcohol Sclerotherapy on Pelvic Pain and Quality of Life in Women With Ovarian Endometriosis

The goal of this clinical trial is to evaluate whether ultrasound-guided alcohol sclerotherapy can improve pelvic pain and quality of life in women aged 18 to 45 diagnosed with ovarian endometriomas, compared to expectant management. The main questions it aims to answer are: 1. \- Does sclerotherapy significantly reduce pelvic pain compared to expectant management? 2. \- Does sclerotherapy improve quality of life as measured by the EHP-5 score? Researchers will compare the sclerotherapy group to the expectant management group to determine whether the intervention leads to greater improvement in pain and quality of life. Participants will: * Be randomly assigned to one of two groups: (1) Sclerotherapy group: undergo ultrasound-guided puncture and alcohol sclerotherapy; (2) Control group: expectant management * Complete quality of life and pain assessments at baseline and after 6 months * Provide blood and urine samples for biomarker analysis (e.g., cortisol, IL-6, hsCRP, catecholamines) * Undergo ovarian reserve assessments (AMH, antral follicle count) * Be followed for adverse events, recurrence, fertility outcomes, and treatment-related costs The study will follow an intention-to-treat and per-protocol analysis approach.

Laparoscopic Sclerotherapy for the Management of Ovarian Endometriomas

The objective of this study is to evaluate the effect of laparoscopic sclerotherapy on ovarian reserve and its overall efficacy in the treatment of endometriomas. Ovarian reserve will be assessed using preoperative and postoperative anti-Müllerian hormone (AMH) levels and antral follicle count (AFC). Traditionally, ovarian endometriomas are managed by complete cystectomy; however, multiple studies including a large systematic review and meta-analysis-have demonstrated that cystectomy significantly reduces ovarian reserve, with an average decline in AMH of 1.77 ng/mL within one to six weeks postoperatively without recovery to baseline after many months. Sclerotherapy has historically been a potential alternative, typically performed by interventional radiology via transvaginal, transabdominal, or transgluteal drainage. This percutaneous approach, however, precludes direct visualization of the cyst and surgical management of concurrent conditions including endometriosis peritoneal disease, excision, adhesions, or tubal disease. Several studies have explored the feasibility and effectiveness of laparoscopic sclerotherapy, reporting encouraging results regarding its safety, increased AFC compared with cystectomy, and comparable pregnancy rates. Nonetheless, none of these studies have been conducted in the United States, and few have utilized a laparoscopic approach. Further research is therefore warranted to establish the accessibility and reproducibility of this technique. The investigators aim to conduct the first U.S.-based study evaluating the impact of laparoscopic sclerotherapy on ovarian reserve. The primary outcome will be the change in AMH and AFC at six weeks postoperatively. Consistent with prior evidence, the investigators hypothesize that laparoscopic sclerotherapy will result in a smaller decline in ovarian reserve compared with traditional cystectomy.

Ablative Technique For Ovarian Preservation In Endometrioma

The goal of this clinical trial is to compare pregnancy rates after different surgical treatments for endometriomas in adult women who have one or more ovarian cysts (endometriomas) larger than 2 cm requiring surgery. The main questions it aims to answer are: How many women become pregnant within 24 months after surgery ? What are the birth rates and different types of pregnancies (natural, with fertility treatments, and those continuing beyond 12 weeks)? How often do the endometriomas come back after surgery? What surgery-related complications occur? How do pain levels change after treatment? Researchers will compare different surgical treatment groups to see if one approach results in better pregnancy outcomes and fewer complications. Participants will: Be randomly assigned to different surgical treatment groups Undergo surgery for their endometriomas and endometriosis Attend follow-up visits at 3 months and 24 months after the procedure Have their pregnancy outcomes, pain levels, and potential complications monitored throughout the study period

The Therapy of Large Endometrioma

Endometrioma's prevalence is between 23 and 55%. It causes pelvic pain, decrease fertility and ovarian reserve. Currently, there's no recommendation about large endometrioma's treatment and there's no information on the best treatment to limit recurrences, preserve fertility and ovarian reserve. In Lille university hospital, simple laparoscopic drainage associated with hormonal therapy is practiced to reduce the risk of cystectomy. This protocol will be evaluated with an observational and prospective study, including women of childbearing age having endometrioma measuring 6 cm or above. The aim of this study is to assess if cyst drainage associated with GnRH agonist, could decrease endometrioma recurrences, deleterious effect on ovarian reserve and evaluate impact on anti-mullerian hormone

Endometrioma Ethanol Sclerotherapy - Prospective Cohort Study Protocol

Ovarian endometriomas are cystic masses lined with endometrial tissue that contains fluid arising from a collection of menstrual debris. Ovarian endometriomas clinical manifestations includes pelvic pain, dysmenorrhea, dysfunctional uterine bleeding, and infertility. Endometriomas are most commonly treated either medically or by surgical excision. Ultrasonography (US)-guided aspiration and sclerotherapy is a new approach. Its mechanism of action is believed to be destruction of the inner epithelial lining, which is followed by inflammation and fibrosis, eventually resulting in regression of the cyst. The main advantage in this approach is the avoidance of collateral damage to the ovary.

Estetrol/Drospirenone to Reduce the Average Size of Endometriomas

Endometriosis, a chronic gynecological disorder associated with pain and infertility, is a common condition affecting approximately one in ten women. Up to 50% of patients with endometriosis have ovarian endometriomas (or "chocolate cysts"). These cysts directly impact fertility and ovarian reserve (ie. ability to have children) and can cause additional symptoms in women such as added pain, discomfort, and surgical emergencies (cyst rupture, or more rarely twisting). While endometriomas tend to require surgical excision as a solution, medical management with a variety of medications has been shown to be effective in reducing their size. Medical management (ie. medications and treatments that don't involve surgery) to reduce cyst size can help relieve symptoms either as a long term solution, before fertility treatments, or temporarily until surgery can be offered. Because the COVID-19 pandemic caused significantly reduced access to surgery and resources, medical management has become important for relief of the overburdened healthcare network. The purpose of this study is to see how effective Estetrol/drospirenone, a combined oral contraceptive (COC), is in the reduction of ovarian endometriomas after a 3- and 6-month period of treatment. This single arm interventional study will recruit women 18 years or older with an ovarian endometrioma of at least 3cm, who are seeking a hormonal treatment for their endometrioma(s). Consenting participants of the study will take Estetrol/drospirenone once daily, orally, for a 6 month duration. An ultrasound assessment of ovarian endometrioma(s) will be performed before starting the drug (0 months), and will be repeated at 3-months and 6-months time. At each of these hospital visits (0, 3 \& 6 months), participants will have their weight and blood pressure measured, and they will complete questionnaires regarding their endometriosis symptoms, incidence of amenorrhea, compliance and incidence of any adverse effects.

Suture of the Ovary After Enucleation of Ovarian Endometrioma

Endometriosis is an estrogen-dependent chronic disease, characterized by the presence of ectopic endometrial-like tissue outside the uterine cavity. According to the most updated guidelines of the European Society of Human Reproduction and Embryology (ESHRE), infertile women with endometriomas smaller than 3 cm should be addressed directly to Assisted Reproduction Technology (ART); conversely, for infertile women with endometriomas larger than 3 cm, enucleation of ovarian endometriomas could be considered in order to improve reproductive outcomes (both spontaneous and ART pregnancy rate). To date, literature data do not allow to draw a firm conclusion about the best strategy to reduce ovarian damage during enucleation of ovarian endometriomas: in particular, investigators still lack robust evidence in order to choose between suturing the ovary or not after the enucleation. In this scenario, the aim of our the study will be to compare functional outcomes of the ovary in a group of women undergoing suturing of the ovarian cortex after laparoscopic enucleation of endometriomas (cases) and a group of women undergoing laparoscopic enucleation of endometriomas without subsequent suture of the ovarian cortex.
