Myoma;Uterus

The goal of this clinical trial is to compare two surgical techniques for reducing blood loss during transabdominal myomectomy in women with symptomatic uterine fibroids. The main question it aims to answer is whether bilateral uterine artery ligation reduces intraoperative blood loss more effectively than pericervical mechanical tourniquet application, without increasing operative complications. Researchers will compare bilateral uterine artery ligation with pericervical mechanical tourniquet application during open myomectomy to evaluate blood loss and surgical safety. Participants will undergo elective transabdominal myomectomy and will be randomly assigned to one of the two vascular control techniques before myoma enucleation.

The goal of this randomized clinical trial is to determine whether intramyometrial ergometrine injection or intramyometrial carbetocin injection is more effective in reducing blood loss during and after abdominal myomectomy in women undergoing surgery for symptomatic uterine fibroids. The main questions it aims to answer are: Does intramyometrial ergometrine reduce intraoperative and postoperative blood loss during abdominal myomectomy? Does intramyometrial carbetocin reduce intraoperative and postoperative blood loss during abdominal myomectomy? Is there a difference between the two drugs in the need for blood transfusion and postoperative hemoglobin drop? Researchers will compare intramyometrial ergometrine injection with intramyometrial carbetocin injection to see which intervention is more effective in controlling surgical bleeding and improving surgical outcomes. Participants will: Undergo abdominal myomectomy for uterine fibroids Receive either intramyometrial ergometrine or intramyometrial carbetocin during surgery Be monitored for intraoperative blood loss, postoperative blood loss, hemoglobin changes, and need for blood transfusion

This prospective randomized study aims to evaluate whether the application of an intrauterine anti-adhesion gel reduces the incidence of intrauterine adhesions (IUAs) following robotic-assisted laparoscopic myomectomy. Intrauterine adhesions may develop after endometrial trauma during surgery and can negatively affect menstrual function, fertility, and future pregnancy outcomes. Robotic myomectomy offers a minimally invasive approach, but postoperative adhesion formation remains a concern. Sixty-two women undergoing myomectomy will be randomized to receive either intrauterine anti-adhesion gel (intervention group) or no adhesion-prevention method (control group). Adhesions will be assessed by ultrasound and hysteroscopy during follow-up. Secondary outcomes include reproductive results over a 24-month period, such as implantation rate, clinical pregnancy, miscarriage, live birth, pregnancy complications, and neonatal outcomes. The study seeks to determine whether combining a minimally invasive surgical approach with an intrauterine gel provides additional protection against adhesion formation and improves fertility-related outcomes.

In France, uterine fibroids or leiomyomas are the most common benign tumour in women of childbearing age. In 30% of cases, fibroids are symptomatic (menorrhagia, anaemia, pain), in which case surgical management is indicated. This is known as myomectomy, and can be performed by hysteroscopy, laparoscopy (laparoscopy) or laparotomy, depending on the number, size and position of the fibroids. Intraoperative bleeding is the main surgical difficulty. For this reason, a number of studies have focused on ways of minimizing the risk of bleeding. A good surgical indication, prevention of anaemia (iron deficiency) and transient occlusion of the uterine arteries during surgery help to reduce this risk. There are also drugs available to reduce intraoperative bleeding, but few studies have been carried out to assess their real effectiveness. One such product is Misoprostol, commonly used in gynecology. Its muscle-contracting properties suggest that it could have a beneficial effect on bleeding during surgery. What's more, this treatment has been used for many years and is reputed to be very well tolerated. The most frequent side effects are digestive, with a risk of abdominal pain in the form of cramps, nausea or vomiting. The investigators therefore decided to set up the HEMOMYOC study to demonstrate a significant reduction in bleeding during laparotomy or laparoscopic myomectomy after taking oral misoprostol in combination with transient occlusion of the uterine arteries, compared with placebo. It would seem that the ease of use and good tolerance of misoprostol, in combination with transient occlusion of the uterine arteries, could be of real benefit in preventing intraoperative morbidity in myomectomies, whatever the surgical approach. To date, no studies have been carried out in this area.

The main objective is to evaluate the diagnostic accuracy of the MUSA terms and definitions, as defined in the paper by Van den Bosch T, Dueholm M, ea. in 2015, to differentiate between different types of myometrial lesions of more than 1 cm. The primary aim is the diagnostic accuracy of the MUSA terms and definitions and the secondary aim the development of a prediction model.

In 2% to 3% infertility women, myoma is the only factor relevant to their infertility. However, the effects of intramural myoma on fertility are controversial. For infertile women with intramural myoma (types IV, V, VI of FIGO system) of 4 to 6 cm diameter, it is not clear whether myomectomy could improve pregnancy outcomes, especially in women undergoing ART. Besides, rigorous clinical research is needed to explore the changes and relevant biomarkers of endometrial receptivity through multi-omics study in patients undergoing myomectomy and ART treatment. Method Intervention and follow-up: (1) For the control group, evaluation protocols such as salpingography and/or laparoscopic tubal fluxation should be implemented to identify disorders such as hydrosalpinx. (2) Imaging evaluation: all pelvic MRI were performed. Other options such as transvaginal ultrasound are not excluded, but won't replace MRI. Enhanced MRI or DWI may be considered, but are not always required. (3) Surgical intervention: laparoscopic myomectomy is preferred, and abdominal myomectomy is also acceptable. (4) IVF treatment: the IVF regimen should include detailed records of the downregulation plan, number of cycles, frozen or fresh blastocysts. Study endpoints (1) Primary study endpoint: Live birth rate after IVF. (2) Secondary study endpoints: Clinical pregnancy rate after IVF; Cumulative pregnancy rate after IVF; Biochemical pregnancy rate after IVF; Sustained pregnancy rate after IVF (≥20 weeks); Miscarriage rate after IVF; Cycles of IVF; Pregnancy-related complications; Perinatal maternal and neonatal complications. (3) Exploratory endpoints: The correlation between imaging index and assisted reproductive outcomes, including endometrial thickness, uterine volume, type of endometrial echo, uterine contraction; endometrial vascular index (VI), flow index (FI), tubular flow index (VFI); uterine artery pulsation index (PI), uterine artery resistance index (RI), systolic/diastolic blood pressure of uterine artery (S/D). The correlation between endometrial receptivity and assisted reproductive outcomes is analyzed based on transcriptomics, metabolomics, methylation and proteomics in samples from peripheral blood, endometrial biopsy, endometrial exfoliated cells, cervical exfoliated cells and myoma.
