ACR Appropriateness Criteria® Management of Uterine Fibroids: 2023 Update.

Uterine fibroids are the most common benign tumor in women of reproductive age and can present with symptoms including bleeding, bulk related symptoms, and infertility. Several treatment options are available for the management of uterine fibroids, including medical management, minimally invasive therapies such as uterine artery embolization and MR-guided focused ultrasound ablation, and surgical interventions ranging from laparoscopic myomectomy to open hysterectomy. Given this wide range of therapeutic interventions, it is important to understand the data supporting these interventions and to be able to apply it in different clinical settings. This document provides a summary of recent trials supporting various therapies for uterine fibroids, including recent evidence for MR-guided focused ultrasound ablation and a detailed discussion of fertility outcomes in myomectomy and uterine fibroid embolization. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

The effectiveness of relugolix compared with leuprorelin for preoperative therapy before laparoscopic myomectomy in premenopausal women, diagnosed with uterine fibroids: protocol for a randomized controlled study (MyLacR study).

BACKGROUND: The oral gonadotropin-releasing hormone antagonist relugolix, which temporarily stops menstruation, is used to treat heavy menstrual bleeding, pelvic pressure, and low back pain in women with uterine fibroids. Treatment can also help women recover from low hemoglobin levels and possibly shrink the fibroids. However, evidence of preoperative use of relugolix before laparoscopic myomectomy is limited. Nevertheless, the treatment could reduce interoperative blood loss, decrease the risk of developing postoperative anemia, and shorten the operative time. Thus, we aim to test whether 12-week preoperative treatment with relugolix (40 mg orally, once daily) is similar to or not worse than leuprorelin (one injection every 4 weeks) to reduce intraoperative blood loss. METHODS: Efficacy and safety of preoperative administration of drugs will be studied in a multi-center, randomized, open-label, parallel-group, noninferiority trial enrolling premenopausal women ≥ 20 years of age, diagnosed with uterine fibroids and scheduled for laparoscopic myomectomy. Participants (n = 80) will be recruited in the clinical setting of participating institutions. The minimization method (predefined factors: presence or absence of fibroids ≥ 9 cm and the International Federation of Gynecology and Obstetrics [FIGO] type 1-5 fibroids) with randomization is used in a 1:1 allocation. Relugolix is a 40-mg oral tablet taken once a day before a meal, for 12 weeks, up to the day before surgery. Leuprorelin is a 1.88 mg, or 3.75 mg subcutaneous injection, given in three 4-week intervals during patient visits before the surgery. For the primary outcome measure of intraoperative bleeding, the blood flow is collected from the body cavity, surgical sponges, and collection bag and measured in milliliters. Secondary outcome measures are hemoglobin levels, myoma size, other surgical outcomes, and quality-of-life questionnaire responses (Kupperman Konenki Shogai Index and Uterine Fibroid Symptoms-Quality of Life). DISCUSSION: Real-world evidence will be collected in a clinical setting to use pre-treatment with an oral gonadotropin-releasing hormone antagonist to reduce intraoperative bleeding in women who undergo laparoscopic myomectomy. TRIAL REGISTRATION: jRCTs031210564 was registered on 19 January 2022 in the Japan Registry of Clinical Trials ( https://jrct.niph.go.jp ).

Giant uterine tumor and miscarriage: how to proceed?

Expanding uterine masses can be the cause of pregnancy loss and add technical difficulties to uterus evacuation due to the intense anatomical distortion of the endocervical canal and uterine cavity. The literature is scarce in the peculiarities of the management of missed abortions in uterus with important distorted anatomies. We report a case of a primigravida patient who presented a rapid and expressive increase of abdominal volume due to a giant uterine mass, evolving to miscarriage. Ultrasound can be a useful tool, allowing visualization of the endocervical path and uterine cavity, helping to perform uterine evacuation in the presence of anatomical distortion without compromising the reproductive future. To the best of our knowledge, no such case has been previously reported.

Vaginal leiomyoma in a goat expressing the nuclear progesterone receptor (PGR): a case report.

BACKGROUND: The risk of developing tumorous diseases in the genital tract also increases with age in animals. One of the classified tumor types is genital leiomyoma. Presently, our understanding of the pathogenesis of this tumor in goats is, however, limited. This accounts also for the information regarding the presence of steroid hormone receptors and, thus, possible responsiveness to circulating steroids. CASE PRESENTATION: This study describes the case of a vaginal tumor in a seven-year-old Anglo-Nubian goat. The goat was presented due to blood mixed vaginal discharge. Per vaginal examination a singular pedunculated mass in the dorsum of the vagina measuring approximately 3 cm x 4 cm x 4 cm was revealed. After administering epidural anesthesia, the mass was removed electrothermally. There were no postoperative complications. The histopathological examination identified the mass as a leiomyoma. The immunohistochemical examination revealed the presence of the nuclear progesterone receptor (PGR) in the tumor tissue. One year after the surgery, during the follow-up examination, the goat was in good overall health, and the owners had not observed any recurrence of vaginal discharge. CONCLUSIONS: When observing vaginal discharge in goats, it is important to consider the possibility of genital tract tumors. These tumors may express sex steroid receptors. In the future, it is worth considering the investigation of potential approaches for preventing tumorigenesis or treating the tumor, such as castration or the administration of antiprogestogens.

Achieving NPVR ≥ 80% as technical success of high-intensity focused ultrasound ablation for uterine fibroids: a cohort study.

OBJECTIVE: To report the long-term re-intervention of patients with uterine fibroids after ultrasound-guided high-intensity focused ultrasound (USgHIFU) ablation and to analyse the influencing factors of re-intervention in patients in the NPVR ≥ 80% group. MATERIALS AND METHODS: Patients with a single uterine fibroid who underwent USgHIFU at our hospital from January 2012 to December 2019 were enrolled. The patients were divided into four groups according to different nonperfusion volume ratio (NPVR). Kaplan-Meier survival curve was used to analyse long-term re-intervention in different NPVR groups, and Cox regression was used to analyse the influencing factors of re-intervention in the NPVR ≥ 80% group. MAIN RESULTS: A total of 1,257 patients were enrolled, of whom 920 were successfully followed up. The median follow-up time was 88 months, and the median NPVR was 85.0%. The cumulative re-intervention rates at 1, 3, 5, 8 and 10 years after USgHIFU were 3.4%, 11.8%, 16.8%, 22.6% and 24.1%, respectively. The 10-year cumulative re-intervention rate was 37.3% in the NPVR < 70% group, 31.0% in the NPVR 70-79% group, 18.2% in the NPVR 80-89% group and 17.8% in the NPVR ≥ 90% group (P < 0.05). However, no difference was found between the group of NPVR 80-89% and the group of NPVR ≥ 90% (P = 0.499). Age of patients and signal intensity on T2-weighted imaging (T2WI) of tumours were found to be independent risk factors for long-term re-intervention in the NPVR ≥ 80% group. A younger age and greater signal intensity on T2W images corresponded to a greater risk of re-intervention. CONCLUSION: USgHIFU, an alternative treatment for uterine fibroids, has reliable long-term efficacy. NPVR ≥ 80% can be used as a sign of technical success, which can reduce re-intervention rates. However, an important step is to communicate with patients in combination with the age of patients and the signal intensity on T2WI of fibroids. TRIAL REGISTRATION: This retrospective study was approved by the ethics committee at our institution (Registration No. HF2023001; Date: 06/04/2023). The Chinese Clinical Trial Registry provided full approval for the study protocol (Registration No. CHiCTR2300074797; Date: 16/08/2023).

A urethral leiomyoma presenting with dysuria: A rare case report.

RATIONALE: Leiomyoma is a benign smooth muscle tumor which is rarely found in urethra. We hereby report a case of a 44-year-old female who presented with complaints of dysuria. PATIENT CONCERNS: A 44-year-old female patient presented to the urology outpatient clinic with symptoms of dysuria. The patient described the presence of a protrusion from the urethra during urination. DIAGNOSIS: Urethral leiomyoma. INTERVENTIONS: Physical examination confirmed a solid urethral mass. CT scan and USG reports indicated that the mass originated from the mid-urethra with vascularity at the base. We performed a complete resection of the urethral mass. The patient was discharged after 3 days of observation. OUTCOME: During a follow-up after 1 month, the patient reported improved urinary flow and no occurrence of hematuria. The patient recovered well after discharge. LESSON: Urethral leiomyoma is a rare benign tumor that is often misdiagnosed in clinical practice. Diagnosis requires careful clinical examination. Surgical removal usually works well. It is important to remember that in some cases of acute urinary retention, it can be caused by a complete obstruction of a mass in the urethra. Urologists should be more cautious and experienced in handling such cases.

Primary omental smooth muscle tumor in an adult male: a diagnostic dilemma for leiomyoma: a case report.

BACKGROUND: The greater omentum comprises peritoneal, adipose, vascular, and lymphoid tissues. Most omental malignancies are metastatic tumors, and the incidence of primary tumors is rare. We report on a prior omental smooth muscle tumor case in an adult male patient. CASE PRESENTATION: A 54-year-old Japanese male patient with no relevant medical history was diagnosed with an abdominal mass during a routine medical checkup. Subsequent contrast-enhanced computed tomography revealed a mass of approximately 3 cm in size in the greater omentum, and a laparotomy was performed. A 27 × 25 × 20 mm raised lesion was found in the omentum. Microscopically, spindle cells were observed and arranged in whorls and fascicles. Individual tumor cells had short spindle-shaped nuclei with slightly increased chromatin and were characterized by a slightly eosinophilic, spindle-shaped cytoplasm. The mitotic count was less than 1 per 50 high-power fields. The tumor cells showed positive immunoreactivity for α smooth muscle actin, HHF35, and desmin on immunohistochemical examination. The Ki-67 labeling index using the average method was 1.76% (261/14806). No immunoreactivity was observed for any of the other tested markers. We considered leiomyoma owing to a lack of malignant findings. However, primary omental leiomyoma has rarely been reported, and it can be difficult to completely rule out the malignant potential of smooth muscle tumors in soft tissues. Our patient was decisively diagnosed with a primary omental smooth muscle tumor considering leiomyoma. Consequently, the patient did not undergo additional adjuvant therapy and was followed up. The patient was satisfied with treatment and showed neither recurrence nor metastasis at the 13-month postoperative follow-up. DISCUSSION AND CONCLUSION: We encountered a primary smooth muscle tumor of the greater omentum with no histological findings suggestive of malignancy in an adult male patient. However, omental smooth muscle tumors are extremely difficult to define as benign, requiring careful diagnosis. Further case reports with long-term follow-up and case series are required to determine whether a true omental benign smooth muscle tumor (leiomyoma) exists. In addition, proper interpretation of the Ki-67 labeling index should be established. This case study is a foundation for future research.

'Just Get A Hysterectomy'.

An African American woman with uterine fibroids is advised to get a hysterectomy, despite the availability of less life-altering options.

Nonpuerperal uterine inversion caused by an adenosarcoma: A case report.

INTRODUCTION: Eighty-five per cent of uterine inversions are puerperal. Non-puerperal uterine inversion is usually caused by tumours that exert a traction force on the fundus of the uterus. This causes the uterus to be partially or completely inverted. It is commonly related to benign tumours like submucosal leiomyomas. Nevertheless, malignancies are an infrequent association. CASE PRESENTATION: We report a case of a 35-year-old female patient, medically and surgically free, gravida0 para0, complaining of menometrorrhagia associated with pelvic pain for 2 years. A suprapubic ultrasound scan showed an enlarged, globular uterus with a heterogeneous, undefined mass of 49 mm in size. MRI scan showed the appearance of a U-shaped uterine cavity and a thickened inverted uterine fundus with an endometrial infiltrating mass of 25 mm. Intraoperative exploration showed uterine inversion involving the ovaries; the fallopian tubes and the round ligaments and a necrotic intracavitary mass. The malignancy of the tumor was confirmed through anatomopathological examination as Adenosarcoma. CONCLUSIONS: Uterine inversion is rare outside the puerperal period, and malignant etiology must not be overlooked. Therefore, comprehensive care with meticulous etiological investigation is crucial.

Intravoxel incoherent motion (IVIM)-derived perfusion fraction mapping for the visual evaluation of MR-guided high intensity focused ultrasound (MR-HIFU) ablation of uterine fibroids.

BACKGROUND: A method for periprocedural contrast agent-free visualization of uterine fibroid perfusion could potentially shorten magnetic resonance-guided high intensity focused ultrasound (MR-HIFU) treatment times and improve outcomes. Our goal was to test feasibility of perfusion fraction mapping by intravoxel incoherent motion (IVIM) modeling using diffusion-weighted MRI as method for visual evaluation of MR-HIFU treatment progression. METHODS: Conventional and T2-corrected IVIM-derived perfusion fraction maps were retrospectively calculated by applying two fitting methods to diffusion-weighted MRI data (b = 0, 50, 100, 200, 400, 600 and 800 s/mm2 at 1.5 T) from forty-four premenopausal women who underwent MR-HIFU ablation treatment of uterine fibroids. Contrast in perfusion fraction maps between areas with low perfusion fraction and surrounding tissue in the target uterine fibroid immediately following MR-HIFU treatment was evaluated. Additionally, the Dice similarity coefficient (DSC) was calculated between delineated areas with low IVIM-derived perfusion fraction and hypoperfusion based on CE-T1w. RESULTS: Average perfusion fraction ranged between 0.068 and 0.083 in areas with low perfusion fraction based on visual assessment, and between 0.256 and 0.335 in surrounding tissues (all p < 0.001). DSCs ranged from 0.714 to 0.734 between areas with low perfusion fraction and the CE-T1w derived non-perfused areas, with excellent intraobserver reliability of the delineated areas (ICC 0.97). CONCLUSION: The MR-HIFU treatment effect in uterine fibroids can be visualized using IVIM perfusion fraction mapping, in moderate concordance with contrast enhanced MRI. IVIM perfusion fraction mapping has therefore the potential to serve as a contrast agent-free imaging method to visualize the MR-HIFU treatment progression in uterine fibroids.

A case report of uterine leiomyosarcoma: unusual clinical presentation with unilateral hydronephrosis and importance of an appropriate diagnosis.

Uterine leiomyosarcoma is a rare malignant gynecologic tumor that arises from the myometrial or endometrial stromal precursor cells. This tumor has the highest prevalence in the pre- and post-is more frequent between 40 and 60 years old. It has a very unfavorable prognosis: only early-stage tumors have an acceptable prognosis; unfortunately, it is often diagnosed accidentally, typically on an advanced stage, when hematological metastases have already spread. Surgery is the main treatment strategy, while systemic treatment and radiotherapy are not recommended due to the lack of results. Since metastatization is mainly hematological, lymphadenectomy is not recommended. Recent progresses have been achieved in advanced and recurrent disease, often inoperable, thanks to new chemotherapies, target therapies and immunotherapies. We reported the case of a 51-year-old woman evaluated for lumbar pain in the right region compatible with renal colic. The ultrasound evaluation revealed right hydronephrosis and the presence of a paraovarian or intraligamentary mass compatible with fibroma. The abdominal CT confirmed the presence of a mass with heterogeneous vascularization. Therefore, the patient underwent laparoscopic surgery to remove the lesion which resulted to be a leiomyosarcoma G2. During the following week the patient underwent a laparoscopic hysterectomy. The first step for differential diagnosis consists in the evaluation of clinicopathological features, followed by the analysis of preoperative imaging. Pelvic MRI represents the gold standard, while CT is used to detect metastases. The main issue is that imaging shows limited ability in differential diagnosis between benign and malign smooth muscle tumor. The definitive diagnosis is confirmed by histological analysis; this implies the necessity of improved attentions on the surgical procedure, which is often performed by steps with prolongation of the treatment pathway. To distinguish which fibroids presents a major risk to be misdiagnosed, some risk scores were developed (rPRESS in 2014 and pLMS in 2019), though actually they are not applied in clinical practice. Uterine leiomyosarcoma (uLMS) is rare but causes several deaths in perimenopausal women due to lack of effective treatments, although target therapies represent a future hope. Furthermore, clinical practice needs support through the development and improvement of diagnostic risk scores and their integration into guidelines.

Endoscopic submucosal dissection for the treatment of a large inflammatory fibroid polyp in the gastric antrum prolapsing into the duodenum: A case report.

RATIONALE: Inflammatory fibroid polyp (IFP), also known as Vanek tumor, is a rare, benign gastrointestinal lesion characterized by its inflammatory and fibroid histological features. IFP is often discovered incidentally during endoscopic examinations. It is exceedingly rare for an IFP to prolapse into the duodenum and results in incomplete obstruction of the pylorus. PATIENT CONCERNS: A 64-year-old male patient was admitted to the hospital with recurrent episodes of melena over a 6-month period, along with complaints of dizziness and fatigue in the past 10 days. DIAGNOSES: Gastroscopy showed a giant polypoid mass on the posterior wall of the gastric antrum, prolapsing into the duodenum. Abdominal computer tomography (CT) confirmed the tumor protruding into the duodenum. Pathologic examination of the resected specimen confirmed the IFP diagnosis. INTERVENTIONS: The giant tumor was completely and successfully excised using endoscopic submucosal dissection (ESD). After the surgery, the patient underwent acid suppression and fluid replenishment therapy. OUTCOMES: The patient responded well to ESD and was discharged in stable condition. As of the submission of the case report, there has been no recurrence of the tumor after a 5-month follow-up, and the patient is still under follow-up. LESSONS: While IFPs have traditionally been managed surgically, ESD demonstrates promising treatment outcomes, avoiding the need for surgical distal gastrectomy, and emerges as a safe and effective treatment option.

Diffusion-weighted imaging as a potential non-gadolinium alternative for immediate assessing the hyperacute outcome of MRgFUS ablation for uterine fibroids.

The aim of this study was to investigate the value of diffusion-weighted imaging (DWI) as a potential non-gadolinium alternative for promptly assessing the hyperacute outcome of magnetic resonance-guided focused ultrasound (MRgFUS) treatment for uterine fibroids. In this retrospective study we included 65 uterine fibroids from 44 women, who underwent axial DWI (b-value: 800 s/mm2) and contrast-enhanced (CE) MR within 15 min post-ablation. Two blinded observers independently reviewed the DWI findings of ablated necrotic lesions and measured their volumes on DWI and CE images. The post-ablation DWI images revealed clear depiction of ablative necrotic lesions in all fibroids, which were classified into two types: the bull's eye sign (type 1) and the bright patch sign (type 2). The inter-observer intraclass correlation coefficient for classifying DWI signal types was 0.804 (p < 0.001). Volumetric analysis of ablated necrosis using DWI and CE T1-weighted imaging showed no significant variance, nor did the non-perfused volume ratios (all p > 0.05). Bland-Altman analysis revealed a mean difference of 2.38% and 1.71% in non-perfused volume ratios between DWI and CE, with 95% limits of agreement from - 19.06 to 23.82% and - 18.40 to 21.82%, respectively. The findings of this study support the potential of DWI as a viable non-gadolinium alternative for evaluating the hyperacute outcomes of MRgFUS ablation in uterine fibroids.

Reflections on Postpartum Hysterectomy as a Possible Complication of Cesarean Myomectomy: A Long Debate.

Uterine fibroids are common benign tumors found in fertile women. Numerous obstetrical issues, such as dystocia during labor, fetal hypotrophy, a ruptured amniotic sac, early labor, low-birth-weight newborns, etc., are associated with fibrous pregnant uteri. Cesarean myomectomy is not a common procedure because of the possibility of postpartum hysterectomy or a potentially lethal hemorrhage. For the chosen topic, we present two instances of emergency postpartum hysterectomies following cesarean myomectomy. After a cesarean myomectomy, two women experienced a perioperative hemorrhage that required a postpartum hysterectomy without a salpingo-oophorectomy. A postpartum hysterectomy was required in every instance due to the failure of additional hemostatic techniques to control the bleeding after the cesarean myomectomy. In every case, the location and number of fibroids-rather than their size-were the primary factors leading to the postpartum hysterectomy. In order to ensure that the patient is safe and that the advantages outweigh the dangers, the current trends in cesarean myomectomy include aiming to conduct the procedure either electively or when it offers an opportunity. The treatment is still up for debate because it is unknown how dangerous a second hysterectomy is for people who have had a cesarean myomectomy.

Cesarean Myomectomy: Reflections on Clinical and Surgical Controversies between a New Trans-Decidual Technique vs. Traditional Method.

Up to 70-80% of women of reproductive age may be affected with the most common uterine tumors, known as fibroids or myomas. These benign tumors are the second most prevalent cause of surgery among premenopausal women. Predictions show that the occurrence of myomas in pregnancy will increase, and that the risk of having myomas during pregnancy increases with advanced maternal age. Although most women with fibroids do not experience any symptoms during pregnancy, up to 30% of women experience problems during pregnancy, childbirth, and the puerperium. The viability of myoma excision during cesarean surgery (CS) is a contentious issue raised by the rising incidence of myomas in pregnancy and CS rates. A new surgical procedure for removing fibroids using a trans-endometrial approach, which involves making an incision through the decidua itself, has put into doubt the long-standing practice of cesarean myomectomy (CM) with a trans-serosal approach. Some authors have recently advocated for this last approach, highlighting its advantages and potential uses in real-world situations. The purpose of this paper is to critique the present approach to cesarean myomectomy by analyzing the clinical and surgical distinctions between the two approaches and providing illustrations of the CM methods.

The great debate: Surgical outcomes of laparoscopic versus laparotomic myomectomy. A meta-analysis to critically evaluate current evidence and look over the horizon.

Myomectomy is one of the most common surgical procedure in the field of gynecology. However, the role of laparoscopic myomectomy is still debated for many factors, including surgical considerations, safety and fertility concerns, long-term outcomes, and cost-related issues. The aim of this study is to evaluate the surgical peri- and post-operative outcomes of laparoscopic and abdominal myomectomy. A systematic search for studies was performed up to June 2023 through MEDLINE, Pubmed, Embase. Studies reporting the comparison of surgical and obstetrical outcomes in laparoscopic versus laparotomic myomectomy were included for the following outcomes: time of surgery, estimated blood loss, decrease of postoperative hemoglobin, hospital stay, intra-operative complication rates, postoperative complications rates, postoperative analgesic use, postoperative pain at 24 h and pregnancy rate. The meta-analysis was performed using the Cochrane Review software. Fifty-six relevant articles were retrieved through the process of evidence acquisition. Eleven articles met inclusion criteria, for a total of 2,133 patients undergoing laparoscopic or laparotomic myomectomy. The estimated blood loss [standard mean differences (SMD) 0.72, IC 95 % 0.22 to 1.22], the hospital stays [SMD 3.12, IC 95 % 0.57 to 4.28], were significantly lower in laparoscopic than in open group. No statistically significant difference in intra-operative and post-operative complication rates, in pregnancy rate and others obstetrical outcomes between two surgical approaches were found. The findings of present metanalysis suggest that laparoscopic myomectomy offers multiple benefits, including reduced blood loss, shorter hospital stays, and less postoperative analgesic need, without a significant increase in complication rates and similar results in obstetrical outcomes when compared to abdominal myomectomy. However, the presence of few randomized studies on selected population may limit the generalizability of the findings to the entire population. Therefore, more well-designed studies or large population programdata to draw definitive conclusions are therefore warranted.

Enhancing surgical performance: the role of robotic surgery in myomectomies, a systematic review and metanalysis.

Examine the role, benefits, and limitations of robotic surgery in myomectomies compared to laparoscopic and open surgical approaches. This review sourced data from CENTRAL, Pubmed, Medline, and Embase up until May 1, 2023. Full articles comparing clinical outcomes of robotic myomectomy with open or laparoscopic procedures were included without language restriction. Initially, 2150 records were found. 24 studies were finally included for both qualitative and quantitative analyses. Two investigators independently assessed all reports following PRISMA guidelines. Meta-analysis was conducted using the software "Review Manager Version 5.4". Risk-of-bias was assessed using the Newcastle-Ottawa scale. Sensitivity analysis was conducted, when feasible. In a comparison between robotic and laparoscopic myomectomies, no significant difference was observed in fibroid weights and the size of the largest fibroid. Robotic myomectomy resulted in less blood loss, but transfusion rates were comparable. Both methods had similar complication rates and operative times, although some robotic studies showed longer durations. Conversion rates favored robotics. Hospital stays varied widely, with no overall significant difference, and pregnancy rates were similar between the two methods. When comparing robotic to open myomectomies, open procedures treated heavier and larger fibroids. They also had greater blood loss, but the robotic approach required fewer transfusions. The complication rate was slightly higher in open procedures. Open surgeries were generally faster, postoperative pain scores were similar, but hospital stays were longer for open procedures. Pregnancy rates were comparable for both robotic and open methods. Robotic surgery offers advancement in myomectomy procedures by offering enhanced exposure and dexterity, leading to reduced blood loss and improved patient outcomes.

Changes in liver and kidney function, red blood cell count and hemoglobin levels 1 day after ultrasound-guided percutaneous microwave ablation for uterine fibroids.

OBJECTIVE: To investigate the changes in liver and kidney function, red blood cell (RBC) count and hemoglobin (HGB) levels in patients undergoing ultrasound-guided percutaneous microwave ablation (UPMWA) for uterine fibroids on postoperative day 1. METHODS: The changes in liver and kidney function, RBC count and HGB levels in 181 patients who underwent selective UPMWA in the Second Affiliated Hospital of Shantou University Medical College, China, between August 2017 and January 2023 were retrospectively analyzed. RESULTS: All patients underwent UPMWA for uterine fibroids; 179 patients had multiple uterine fibroids and 2 patients had single uterine fibroids. The maximum fibroid diameter ranged from 18 to 140 mm, with an average of 68.3 mm. Ultrasound imaging was used to confirm that the blood flow signal within the mass had disappeared in all patients, indicating that the ablation was effective. Within 24 h, compared with before UPMWA, levels of total bilirubin, direct bilirubin, indirect bilirubin and aspartate aminotransferase had significantly increased (p < 0.01), whereas levels of total protein, albumin, globulin, alanine aminotransferase, creatinine and urea had significantly decreased (p < 0.01). Acute kidney injury (AKI) occurred in 1 of the 181 patients. The RBC count and HGB levels decreased significantly after UPMWA (p < 0.01). CONCLUSION: Ultrasound-guided percutaneous microwave ablation for uterine fibroids can impose a higher detoxification load on the liver and cause thermal damage to and the destruction of RBCs within local circulation, potentially leading to AKI. Protein levels significantly decreased after UPMWA. Therefore, perioperative organ function protection measures and treatment should be actively integrated into clinical practice to improve prognosis and enhance recovery.

Laparoscopic continuous seromuscular circumsuture for myomectomy: a real-world, retrospective, East-Asian cohort study.

OBJECTIVE: This study aimed to introduce a novel laparoscopic haemostasis for myomectomy and investigate the independent risk factors for uterine fibroid recurrence. DESIGN: A retrospective cohort study. SETTING: Following strengthening the reporting of observational studies in epidemiology (STROBE) criteria, a retrospective study of prospectively collected available data of the consecutive patients who underwent the myomectomy in the department of obstetrics and gynaecology of the single centre between February 2018 and December 2020. PARTICIPANTS: 177 patients who underwent laparoscopic myomectomy resection were enrolled in the present cohort study. MATERIALS AND METHODS: Patients were classified into two groups according to their different methods of haemostasis in laparoscopic surgery. Recurrence-free survival was compared between the groups during an average follow-up of nearly 2 years. RESULTS: Of the 177 patients from 672 consecutive patients in the retrospective cohort, laparoscopic circular suture and baseball suture were carried out in 102 (57.6%) and 75 (42.4%) patients, respectively. The total amount of blood lost during surgery varied significantly (37.6 vs 99.5 mL) (p<0.001). Univariable analyses identified that age ≥40 years, position at intramural myoma, multiple fibroids and largest fibroid volume ≥50 mm3 (HR 2.222, 95% CI 1.376 to 3.977, p=0.039; HR 3.625, 95% CI 1.526 to 6.985, p=0.003; HR 3.139, 95% CI 1.651 to 5.968, p<0.001; HR 2.328, 95% CI 0.869 to 3.244, p=0.040, respectively) are independent risk factor of the recurrence of uterine fibroids. The formula of the nomogram prediction model was established as the practical clinical tool. CONCLUSION: The laparoscopic continuous seromuscular circumsuture for myomectomy can effectively reduce the amount of surgical bleeding and accelerate the perioperative recovery for surgical safety. The main factors affecting the recurrence of uterine fibroids were age, location, number and volume of uterine fibroids. The nomogram can more straightforwardly assist clinicians to determine the risk of recurrence after laparoscopic myomectomy.

Surgical impact of bilateral transient occlusion of uterine and utero-ovarian arteries during laparoscopic myomectomy.

The objective of this article is to compare the amount of intraoperative blood loss during laparoscopic myomectomy when performing bilateral transient clamping of the uterine and utero-ovarian arteries versus no intervention. It´s a randomized controlled prospective study carried out in the Department of Obstetrics and Gynecology Ramón y Cajal University Hospital and HM Montepríncipe-Sanchinarro University Hospital, Madrid, Spain, in women with fibroid uterus undergoing laparoscopic myomectomy. Eighty women diagnosed with symptomatic fibroid uterus were randomly assigned to undergo laparoscopic myomectomy without additional intervention (Group A) or temporary clamping of bilateral uterine and utero-ovarian arteries prior to laparoscopic myomectomy (Group B). Estimated blood loss, operating time, length of hospital stay, and postoperative hemoglobin values were compared in both groups. The number of fibroids removed was similar in both groups (p = 0.77). Estimated blood loss was lower in the group of patients with prior occlusion of uterine arteries (p = 0.025) without increasing operating time (p = 0.17) nor length of stay (p = 0.17). No patient had either intra or postoperative complications. Only two patients (2.5%) required blood transfusion after surgery. We conclude that temporary clamping of bilateral uterine arteries prior to laparoscopic myomectomy is a safe intervention that reduces blood loss without increasing operative time.
