INTRODUCTION: This was a single-center pilot study that sought to describe an innovative use of 4DryField® PH (premix) for preventing the recurrence of intrauterine adhesions (IUAs) after hysteroscopic adhesiolysis in patients with Asherman's syndrome (AS). MATERIAL AND METHODS: Twenty-three patients with AS were enrolled and 20 were randomized (1:1 ratio) to intrauterine application of 4DryField® PH (n = 10) or Hyalobarrier® gel (n = 10) in a single-blind manner. We evaluated IUAs (American Fertility Society [AFS] score) during initial hysteroscopy and second-look hysteroscopy one month later. Patients completed a follow-up symptoms questionnaire three and reproductive outcomes questionnaire six months later. RESULTS: The demographic and clinical characteristics, as well as severity of IUAs, were comparable in both groups. The mean initial AFS score was 9 and 8.5 in the 4DryField® PH and Hyalobarrier® gel groups, respectively (p = .476). There were no between-group differences in AFS progress (5.9 vs. 5.6, p = .675), need for secondary adhesiolysis (7 vs. 7 patients, p = 1), and the follow-up outcomes. CONCLUSION: 4DryField® PH could be a promising antiadhesive agent for preventing the recurrence of IUAs, showing similar effectiveness and safety to Hyalobarrier® gel. Our findings warrant prospective validation in a larger clinical trial. CLINICAL TRIAL REGISTRY NUMBER: ISRCTN15630617.

OBJECTIVE: To study the effectiveness of a new intrauterine degradable polymer film (Womed Leaf) in the management of moderate to severe intrauterine adhesions (IUA). DESIGN: PREG-2 study was a multicenter, double-blind, randomized, controlled, stratified, two-arm superiority clinical trial conducted in 16 centers in seven countries. SETTING: Not applicable. PATIENT(S): Patients ≥18 years scheduled for hysteroscopic adhesiolysis because of symptomatic severe or moderate adhesions (according to American Fertility Society [AFS] IUA score) were considered eligible for the study. INTERVENTION(S): After adhesiolysis, patients were randomized at a 1:1 ratio to either have a Womed Leaf film inserted (intervention group) or not (control group). MAIN OUTCOME MEASURE(S): The primary effectiveness endpoint of the study was the change in AFS IUA score on second-look hysteroscopy (SLH), assessed by an independent evaluator, and compared with baseline. Information on the rate of no IUA and responder rate was collected as secondary effectiveness outcomes, while reported adverse events and patient-reported outcomes as safety and tolerability measures. RESULT(S): Between October 26, 2021, and September 28, 2023, a total of 160 women were randomized (Womed Leaf: n = 75 and controls: n = 85). The reduction in IUA AFS score on SLH was significantly higher in the intervention compared with the control group (mean 5.2 ± 2.8 vs. 4.2 ± 3.2). Similarly, the absence of adhesions on SLH was significantly higher in the intervention group (41% vs. 24%; odds ratio, 2.44; confidence interval, 1.161-5.116). None of the reported adverse events were serious or considered related to the device. CONCLUSION(S): Womed Leaf is effective and safe in the management of symptomatic severe or moderate IUAs. CLINICAL TRIAL REGISTRATION NUMBER: Clinicaltrials.gov identifier: NCT04963179.

The narrative review article is focused on the strengths and limitations of modern imaging methods in the preoperative differential diagnosis of uterine mesenchymal tumours. In order to tailor the surgical procedures, imaging methods, namely ultrasound and magnetic resonance imaging (MRI), should be taken into account as well as clinical symptoms, age, and fertility plans. On ultrasound scans, uterine sarcomas have the appearance of large, usually solitary tumours of non-homogenous structure with irregular cysts, ill-defined outline borders (interrupted capsule), absence of calcifications with acoustic shadowing, and moderate to rich internal vascularisation. Rapid growth between follow-ups or atypical growth in peri- or post-menopause is also a sign of malignancy. On MRI, uterine sarcomas are characterized by irregular borders, hyperintense areas on T1-weighted and T2- weighted images, and central non-enhancing necrotic areas. On diffusion-weighted imaging (DWI/MRI), sarcomas exhibit markedly restricted diffusion but there is a significant overlap with some variants of fibroids. Core-needle or hysteroscopic biopsy can be used preoperatively if suspicious features are detected on ultrasound or MRI scans, particularly before myomectomy if fertility preservation is required or when conservative management is considered in asymptomatic women. Other imaging methods, such as positron emission tomography fused with CT (PET-CT) or computed tomography (CT) have limited role to distinguish uterine sarcomas from myomas and are suitable only for staging purposes. The importance of tumour markers including lactate dehydrogenase in preoperative work-up have not been verified yet. Conclusion: Uterine sarcomas can be distinguished from much more common myomas based on a combination of malignant features on ultrasound or MR imaging. In these suspicious cases the type and extent of surgery should be adjusted, avoiding intraperitoneal morcellation, which could lead to iatrogenic tumour spread and worsening of the patient's prognosis.

Three main uterine leiomyoma molecular subtypes include tumors with MED12 mutation, molecular aberrations leading to HMGA2 overexpression, and biallelic loss of FH. These aberrations are mutually exclusive and can be found in approximately 80-90% of uterine leiomyoma, in which they seem to be a driver event. Approximately 10% of uterine leiomyoma, however, does not belong to any of these categories. Uterine leiomyoma with HMGA2 overexpression is the most common subtype in cellular and second most common category of usual leiomyoma. In some of these tumors, rearrangement of HMGA2 gene is present. The most common fusion partner of HMGA2 gene is RAD51B. Limited data suggests that RAD51B fusions with other genes may be present in uterine leiomyoma. In our study, we described two cases of uterine leiomyoma with RAD51B::NUDT3 fusion, which occur in one case of usual and one case of highly cellular leiomyoma. In both cases, no other driver molecular aberrations were found. The results of our study showed that RAD51::NUDT3 fusion can occur in both usual and cellular leiomyoma. RAD51B may be a fusion partner of multiple genes other than HMGA2 and HMGA1. In these cases, RAD51B fusion seems to be mutually exclusive with other driver aberrations defining molecular leiomyoma subtypes. RAD51B::NUDT3 fusion should be added to the spectrum of fusions which may occur in uterine leiomyoma, which can be of value especially in cellular leiomyoma in the context of differential diagnosis against endometrial stromal tumors.

OBJECTIVE: The aim of this study was to analyze the clinical and reproductive outcomes of patients treated with myomectomy who were histologically diagnosed with uterine smooth muscle tumor of uncertain malignant potential (STUMP). METHODS: Patients who were diagnosed with STUMP and underwent a myomectomy at our institution between October 2003 and October 2019 were identified. Variables of interest obtained from the institution's database included patient age, relevant medical history, pre-operative appearance of the tumor on ultrasound, parameters of the surgical procedure, histopathological analysis of the tumor, post-operative clinical course, and course of follow-up, including reinterventions and fertility outcomes. RESULTS: There were a total of 46 patients that fulfilled the criteria of STUMP. The median patient age was 36 years (range, 18-48 years) and the mean follow-up was 47.6 months (range, 7-149 months). Thirty-four patients underwent primary laparoscopic procedures. Power morcellation was used for specimen extraction in 19 cases (55.9% of laparoscopic procedures). Endobag retrieval was used in nine patients and six procedures were converted to an open approach due to the suspicious peri-operative appearance of the tumor. Five patients underwent elective laparotomy due to the size and/or number of tumors; three patients had vaginal myomectomy; two patients had the tumor removed during planned cesarean section; and two underwent hysteroscopic resection.There were 13 reinterventions (five myomectomies and eight hysterectomies) with benign histology in 11 cases and STUMP histology in two cases (4.3% of all patients). We did not observe any recurrence as leiomyosarcoma or other uterine malignancy. We did not observe any deaths related to the diagnosis. Twenty-two pregnancies were recorded among 17 women, which resulted in 18 uncomplicated deliveries (17 by cesarean section and one vaginal), two missed abortions, and two pregnancy terminations. CONCLUSIONS: Our study found that uterus-saving procedures and fertility-preservation strategies in women with STUMP are feasible, safe, and seem to be associated with a low risk of malignant recurrence, even while maintaining the mini-invasive laparoscopic approach.

OBJECTIVE: Case report of a gynecologically polymorbid patient with enhanced myometrial vascularity, and review of current scientific literature on incidence, dia-gnostic method, and management of this phenomenon. CASE REPORT: A 38-year-old patient that has been treated long-term for secondary sterility with a medical history of laparotomic cytoreduction surgery for adenomyosis and subsequent development and treatment of postoperative intrauterine adhesions. Currently presenting with enhanced myometrial vascularity after spontaneous abortion. For symptomatic prolonged course of the observation period without tendency for spontaneous regression and risk of acute hemorrhage, she was initially indicated for selective embolization of uterine arteries and consecutive definitive treatment via hysteroscopic resection. CONCLUSION: Due to low incidence and tendency for spontaneous resorption, early recognition, and correct management of enhanced myometrial vascularity, it still represents a medical challenge.

OBJECTIVE: To summarize recent data and knowledge of laparoscopic power morcellation. METHODS: Review of articles. RESULTS: Laparoscopic morcellation has been introduced to gynecologic surgery in 90s. In 2014, Food and Drug Administration announced negative statement about the morcellation use due to the risk of potential spreading of malignant tumor cells. This statement reduced utilization of morcellation, especially in the United States. Since that, many health institutions and organizations started new researches focused on the safety of this surgical technique. After a couple of years, the morcellation is considered as a useful tool if certain rules are followed. CONCLUSION: Morcellation has a place in laparoscopic operative procedures even in 2022, in condition of correct selection of patients and possible utilization of contained in-bag morcellation.

OBJECTIVE: The purpose of this study was to evaluate the appropriate surgical treatment of adenomyosis and its impact on reproductive outcomes. CONCLUSION: Patients with adenomyosis and fibroids may show a lower pregnancy rate and higher miscarriage rate than healthy individuals. However, there is no standard protocol for their optimal treatment, particularly in pregnancy-seeking or infertile women. Myomectomy is generally a commonly performed procedure that preserves fertility. On the other hand, the role of surgery in extensive uterine adenomyosis remains controversial, because adenomyosis often involves the whole uterus diffusely. It is almost impossible to remove all pathological tissue from the surrounding myometrium. Therefore, this procedure is called debulking/cytoreductive surgery. However, adenomyomectomy has also become a more common type of surgical intervention in recent years.

INTRODUCTION: The aim of this study was to evaluate hysteroscopic findings after laparoscopic and laparotomic myomectomy with a focus on the presence of postoperative intrauterine adhesions in groups of patients with and without perioperative uterine cavity breach (UCB). MATERIAL AND METHODS: This is a historical cohort study. Our database was searched to identify patients with UCB during myomectomy and matched the same number of patients after myomectomy without UCB to create a control group. All relevant data were retrieved from our medical records. In both groups, the results of follow-up hysteroscopy were analyzed. RESULTS: Low prevalence of intrauterine adhesions after myomectomy was observed in only 3.5% of the 170 patients in our samples. No significant difference in the occurrence of synechiae between the patients with and without UCB was found (2 vs. 4, RR 0.5, 95% CI 0.1-2.7, p = .341), nor was the difference in other hysteroscopic findings. Follow-up hysteroscopy was performed with slender optics and expandable casing system without need of any anesthesia in 87.1% of cases. CONCLUSIONS: According to our findings, the prevalence of post-myomectomy intrauterine adhesions after myomectomy is low. Our study did not demonstrate that UCB during myomectomy is a risk factor for the formation of intrauterine synechiae.

INTRODUCTION: This study was designed to evaluate the feasibility and effectiveness of hysteroscopy in the management of symptoms related to endometrial polyps and submucous leiomyomas in women using a levonorgestrel-releasing intrauterine system (LNG-IUS). MATERIAL AND METHODS: Twenty-three LNG-IUS users presenting with endometrial polyps and/or submucous leiomyomas and irregular uterine bleeding were recruited for hysteroscopic examination and surgery. Intrauterine pathology was investigated and treated by hysteroscopic resection with the LNG-IUS in situ, and the effect of the procedure on symptoms was evaluated after three to six months. RESULTS: Intrauterine pathology was successfully resected by hysteroscopy in 23 (100.0%) out of 23 cases. Following hysteroscopy, 18 (78.3%) women reported amenorrhea, one (4.3%) regular spotting, three (13.0%) irregular spotting and one (4.3%) patient resumed normal menstrual cycle. We conclude that 19 (82.6%) patients were postoperatively asymptomatic. All procedures were uncomplicated and 4 (17.4%) were carried out without general anesthesia as office procedures. CONCLUSION: Endometrial polyps and submucous leiomyomas can develop in LNG-IUS users, and this can cause irregular uterine bleeding. Hysteroscopic resection of these pathologies is a feasible method in the clinical management of symptoms.
