Filter by:Uterine leiomyomas, or fibroids, are common benign tumors among women, especially those over 35 years old. They can cause various issues, including heavy menstrual bleeding, anemia, pelvic pain, and pressure symptoms. Surgery is often necessary for symptomatic fibroids, with hysterectomy recommended for women over 40 and myomectomy for those wishing to preserve their uterus. Myomectomy can be performed using different surgical approaches but can be associated with significant morbidity, particularly major blood loss, especially in abdominal myomectomy, where up to 20% of women may require blood transfusion. Various interventions have been introduced to reduce bleeding during myomectomy, such as tourniquets, bupivacaine plus epinephrine infiltration, vasopressin injection, preoperative GnRH agonist administration, and preoperative ascorbic acid injection. However, these strategies may have complications, be ineffective, expensive, or require extra steps. Oxytocin, primarily secreted from the pituitary gland, is crucial for uterine contraction during labor and delivery, and is used to prevent postpartum uterine atony and bleeding. However, caution is needed in its use, especially in women with heart disease or hypovolemia. Misoprostol, a prostaglandin E1 analogue, can reduce bleeding during myomectomy by promoting myometrial contractions and reducing uterine artery blood flow. It can be administered via multiple routes, with rectal administration showing advantages in maintaining high plasma concentrations during surgery. Studies have investigated the effectiveness of single preoperative rectal doses of misoprostol versus preoperative oxytocin in reducing bleeding during abdominal myomectomy.
Fibroids are the most commonly encountered tumors in the female reproductive system. In patients, fibroids most often lead to abnormal uterine bleeding and the resulting anemia. In some cases, they can cause infertility or habitual abortions. Another complaint caused by fibroids is pain due to pressure and effects on adjacent organs. Very large fibroids can lead to abdominal swelling. Therefore, if a patient becomes symptomatic due to fibroids, myomectomy or, if necessary, hysterectomy is required. Because fibroids have a significant blood supply, there is a high risk of intraoperative bleeding and related complications. Additionally, the most common complication in these patients after the operation is bleeding. In many of these patients, intraoperative or postoperative blood transfusions are performed. If bleeding cannot be intervened early in these patients, hemodynamic instability, shock, coagulopathy, and, in the final stage, death can occur due to hemorrhage. Therefore, both intraoperative and postoperative bleeding control is of vital importance in patients undergoing myomectomy.
Augmented Reality is a technology that allows surgeons to superimpose virtual images from preoperative imaging onto the endoscopic vision system intraoperatively. The goal of this clinical trial is to demonstrate that the use of augmented reality during laparoscopic gynecological surgery with a dedicated device could provide assistance to the surgeon, in terms of technical comfort and better visualization of the benign tumor to be resected on a mobile organ.
This is a single-arm clinical trial evaluating the safety and efficacy of ultrasound-guided HIFU (Sonotrip V20) for symptomatic uterine fibroids. 57 cases will be enrolled at a Korean institution. Participants will undergo the HIFU procedure based on a pre-established plan using MRI images. Assessments will be conducted immediately post-procedure and at 4 and 24 weeks. Primary endpoint is fibroid volume reduction at 24 weeks, with secondary endpoints including Non-Perfused Volume Ratio, quality of life, hemoglobin change, pain assessment, and additional medication use. Adverse events will be monitored.
Hysteroscopy is a minimally invasive, diagnostic and therapeutic gynecological surgical technique and the gold standard in the study of the uterine cavity. Thanks to the decrease in the diameter of hysteroscopes and to the vaginoscopic approach, anesthesia is no longer necessary in diagnostic hysteroscopy. Nevertheless, in operative hysteroscopy, given the instrumentalization and the need of cervical dilation, the use of local anesthesia, with or without sedation, is recommended. The different alternatives described in the literature are the following: 1. Cervical/ intracervical block: injection of local anesthetic into the four quadrants of the cervix. 2. Paracervical block: injection of local anesthetic in the cervicovaginal junction at 5 and 7 o'clock positions. 3. Transcervical (uterine) anesthesia: instillation of a local anesthetic agent via catheter through the cervix and into the uterine cavity. 4. Topical cervical anesthesia: application of local anesthetic in gel or spray to the cervix. To assess the best anesthetic pathway to decrease pain during outpatient hysteroscopy, the investigators will perform a prospective multicentric study that compare two types of local anesthesia in outpatient procedural hysteroscopy: paracervical block, that is the actual gold-standard, and transcervical instillation.
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.
ImpactRA is an observational retrospective study. The management of the patient is not modified by this study. This study will be carried out based on the already existing data of the gynecological ward of CHU Clermont-Ferrand between 2016 and 2021. During this period of time, 17 patients have undergone laparoscopy, with surgical indication of myomectomy or adenomyomectomy, aided by augmented reality (AR). The investigators compared these 17 patients that underwent surgery with AR with 17 control patients that underwent the same surgery with the same indication but without AR.
Polyps, intracavitary myomas and retained products of conception (RPOC) are common benign intracavitary lesions of the uterus and frequently cause abnormal uterine bleeding or pain. In general, intracavitary lesions are treated by operative hysteroscopy with bipolar resectoscopic removal under general anaesthesia, performed in the theatre (OR). Potential problems with this approach are thermal damage and impairment of visibility due to loose tissue fragments necessitating multiple entries for tissue removal. Recently, lesion morcellation by hysteroscopy has been introduced as an alternative technique. Compared to the resectoscopic approach, morcellation is reportedly associated with a shorter total procedure time, smaller fluid deficit and number of insertions. A few trials also registered a higher success rate in completeness of resection. No significant differences in odds of surgical complications have been reported. Most hysteroscopic morcellators have diameters up to 8 mm, for which cervical dilation under general anaesthesia is usually needed. Recently, companies have developed hysteroscopic morcellators with smaller diameters, e.g. 6.3 mm for the 19 Fr. intrauterine BIGATTI Shaver (IBS®). This means less need for cervical dilation, and potential use without anesthesia. At this moment, there are no prospective studies available on feasibility of the 19 Fr. intrauterine BIGATTI Shaver (IBS®). Before implementing hysteroscopic morcellation in our department, we need a feasibility study assessing the method in standard conditions in the operation room or in ambulatory setting under sedation. Trial objectives: Assessment of the feasibility of hysteroscopic morcellation of benign uterine intracavitary lesions. The primary objective is to assess the completeness of hysteroscopic resection in patients undergoing the procedure under general anesthesia or sedation. Secondary objectives are to assess perioperative parameters as operation time, need for cervical dilation, adverse events, pain, operator satisfaction; to assess quality of tissue for histological examination; to assess postoperative complications and pain.
Aim and objectives; To compare the efficacy of preoperative administration of dinoprostone 20 mg versus 400 ug misoprostol vaginally in decreasing the amount of bleeding during abdominal myomectomy
Uterine leiomyomas (or fibroids) are a common disease (30% of women over 35 years of age) in women of childbearing age and can cause various symptoms such as menometrorrhagia, dysmenorrhoea, pelvic pain and heaviness, and infertility. Uterine artery embolisation, first used in France in 1990, is a safe, effective and less invasive therapeutic technique than surgical treatment (myomectomy or hysterectomy), particularly in the case of numerous and large fibroids. This technique is validated by the French National College of Gynaecologists-Obstetricians (CNGOF) as an alternative treatment for women who do not wish to become pregnant (grade A recommendation), but at present there is little reliable data concerning fertility, the occurrence of pregnancy and the obstetrical prognosis after uterine artery embolisation for fibroids. A recent systematic review of the literature with meta-analysis published very recently showed that 40.5% of patients with a desire for pregnancy were able to become pregnant after embolisation (CI: 33.3%-48.2%) but that the rates of miscarriage, obstetric complications and low birth weight were not negligible (respectively 33.5% (95% CI: 26.3-41%), 25.4% (95% CI = 13-40.2%) and 10% (95% CI = 6.2-14.6%) (Ghanaati et al. 2020). In France, uterine artery embolisation is performed in more than thirty centres in women who have completed their parental project. On the other hand, in the absence of consistent literature, it is performed in patients of childbearing age, when it represents the only acceptable alternative or in the event of contraindication or refusal of surgery by the patient. To our knowledge, there is no large-scale French study to date on the impact of embolisation on fertility and pregnancy outcomes. The aim of this study is to compile a retrospective database of all cases of uterine artery embolisation for uterine pathology performed at the Georges-Pompidou European Hospital (HEGP) since 2007 and to assess the impact of embolisation on fertility in patients of childbearing age.
