Project description:IntroductionHysterosalpingography (HSG) and hysterosalpingo-foam sonography (HyFoSy) are commonly used tubal patency tests during the fertility work-up. Besides its diagnostic purpose, HSG with oil-based contrast can also be applied for its fertility-enhancing effect, by tubal flushing. HyFoSy is considered as less painful compared with HSG, it lacks exposure to iodinated contrast medium and ionising radiation. The fertility-enhancing effects of HyFoSy are less studied and randomised controlled trials comparing pregnancy rates after HSG and HyFoSy are lacking. This study (FOil study) is initiated to compare the effectiveness of tubal flushing during HSG with oil-based contrast and HyFoSy.Methods and analysisThe FOil study is a nationwide, multicentre, open label, randomised controlled trial with a superiority design. Infertile women with an indication for tubal patency testing during their fertility work-up will be randomly assigned to HSG with oil-based contrast medium or HyFoSy. The primary outcome is conception within 6 months after randomisation leading to live birth. To demonstrate or refute an 8% difference in conception leading to live birth in favour of HSG with oil-based contrast, 1102 women will be included in the trial. A cost-effectiveness analysis from a societal perspective will be performed alongside the trial.Ethics and disseminationThe trial is approved by the Medical Ethics Review Committee of the Amsterdam University Medical Centers (Ref. No. 2022.0884, date: 17 March 2023) and by the boards of the participating hospitals. The findings will be disseminated in peer-reviewed journals and participants will be informed through the patient organisation.Trial registration numberNCT05882188.

Project description:BackgroundTubal pathology is the etiological factor in 20% of couples with female infertility. Historically, diagnostic evaluation of the fallopian tubes has been performed by means of hysterosalpingography (HSG). Hysterosonosalpingography with EXEM® foam is a recent technique with supposedly comparable effectiveness to HSG, but with better tolerability for patients.MethodsTubal patency was assessed in patients who were candidates for intrauterine insemination (IUI) between January 2020 and July 2021. (I) Hysterosonosalpingography with EXEM® foam. (II) If the patient had both tubes patent, IUI was proposed. In case of inconclusive or pathological results, HSG was performed. (III) If the HSG concludes tubal patency, IUI is proposed. On the other hand, if it results in tubal obstruction, in vitro fertilization (IVF) is proposed.ResultsAssessment of tubal patency by HSG showed concordance with previous Hysterosonosalpingography with EXEM® foam results in 45.5% (n=15) of cases of unilateral obstruction and 66.7% (n=6) of cases of bilateral obstruction. When we compare the total cost of HSG (€54,899.46) with the sum of patients who only required Hysterosonosalpingography with EXEM® foam together with those who underwent both tests (€45,575.96), it shows that the latter represents a cost benefit strategy (cost difference €9,323.50).ConclusionsOur results suggest a benefit of €9,323.50 when performing the contingent sequential strategy, in case of pathological or inconclusive results, compared to performing a systematic HSG in all patients. Patients with an obstructive hysterosalpingogram with EXEM® and a patent hysterosalpingogram will be the subgroup that will benefit the most, as IUI can be proposed instead of IVF. In addition, there is a benefit in terms of optimizing the medical procedure, hospital visits and speeding up the time to start assisted reproductive technology (ART).

Project description:IntroductionTubal patency testing is an essential part in the fertility workup of many subfertile women. Hysterosalpingography (HSG) has long been the test of choice in many clinics. There is evidence from a large randomised multicentre trial and from a recent meta-analysis that women who had HSG using oil soluble contrast medium (OSCM) had higher rates of ongoing pregnancy compared with women who underwent this procedure using water contrast. However, the field is moving away from HSG and nowadays hysterosalpingo-foam sonography (Hyfosy) using ultrasound guidance is considered as the first line office tubal patency test. Therefore, a large multicentre randomised clinical trial (RCT) will be initiated to evaluate if flushing the fallopian tubes with OSCM after a normal Hyfosy showing at least one patent fallopian tube will increase the live birth rate as compared with no flushing.Methods and analysisWe plan a multicentre two arm, 1:1 randomised, open-label pragmatic comparative trial in 12 Belgian centres. After informed consent, we will randomise infertile women between 18 and 40 years of age, undergoing Hyfosy as part of the fertility workup to Hyfosy with additional tubal flushing with OSCM versus Hyfosy without additional flushing. Infertility is defined as lack of conception despite 12 months of unprotected intercourse, or three cycles of donor insemination without pregnancy or three ovulatory ovulation induction cycles without pregnancy, all three in combination with at least one patent tube on Hyfosy. Primary endpoint will be live birth with conception within 6 months after randomisation.Ethics and disseminationApproval on 11 May 2021 by the Ethics Committee from ZNA Hospital Antwerp who was the central Ethics Committee for the Clinical Trial Regulation Pilot (Pilot 412) in the 12 centres. The findings from this RCT will be disseminated in peer-reviewed publications and presentations at scientific international meetings.Trial registration numbersEudraCT number: 2020-002135-30 and NCT04379973.

Project description:BACKGROUND:Four-dimensional hysterosalpingo-contrast sonography (4D-HyCoSy) is the preferred way for evaluating fallopian tubal patency and it associated with higher rate of spontaneous conception. However, Few studies have evaluated the influencing factors of spontaneous conception in 4D-HyCoSy and suggested ways to choose treatment options after 4D-HyCoSy. The study was to evaluate the correlation between spontaneous conception outcome and the patients' clinical characteristics as well as tubal patency in infertile women to provide reference on ways to manage the patient after 4D-HyCoSy. METHODS:This was a retrospective study and analysis of two hundred and eighty three (283) infertile patients who underwent a 4D-HyCoSy between December 2014 and October 2017 in our center. Eligible patients were those whose partners semen parameters were normal when based on World Health Organization (WHO) criteria, and had spontaneous conception without clinical interventions after 4D-HyCoSy. RESULT(S):One hundred and sixteen patients (40.9%) conceived spontaneously and the mean conception time was (8.8?±?0.3) months. Within a year after 4D-HyCoSy, the spontaneous conception rate was highest in type VI(62.5%), followed by type IV (46.2%), type III (44.4%), type V (39.4%), type II (33.9%) and type I (14.8%). With Cox regression analysis, two factors associated with spontaneous conception outcome appeared to increase spontaneous conception rate: patients with type IV or type VI tubes and duration of infertility less than 2?years. The age, type of infertility, multiparas, history of pelvic surgery, history of uterine cavity operation, uterine fibromyomata and polycystic ovary were unrelated to spontaneous conception outcome after 4D-HyCoSy. CONCLUSION(S):This study showed that some infertile women could succeed in spontaneous conception after 4D-HyCoSy. Hence, We recommend the usage of 4D-HyCoSy as first line for tubal patency test and infertile patients should be advised to accept 4D-HyCoSy examination as soon as possible. Expectant treatment of about 8-9?months is reported to be feasible for infertile women whose 4D-HyCoSy findings showed one tube patency or poor patency. Alternatively, an immediate clinical intervention is recommended for those with bilateral obstructed tubes .

Project description:A variety of procedures have been used for family planning. One of these is sterilization surgery, which can be reversed by a tubal reanastomosis. In the present report, we compare Robot-assisted tubal reanastomosis sterilization with other methods of family planning and discuss factors related to the choice of the approach. The keywords used for the electronic search in PubMed were family planning, sterilization, Robot-assisted, tubal reanastomosis, depression, and regret. The decision in favor of or against sterilization surgery has been a sensitive issue for several years. Robot-assisted technology is a modern and precise approach. It has contributed to the flexibility of the decision between sterilization and its reversal through tubal reanastomosis, as well as enhanced the success rate of the surgery. Based on our analysis of the published literature, we believe that Robot-assisted tubal anastomosis is the optimum approach. However, to ensure the quality of health care, the surgeon must be well trained, well versed with the anatomy of the fallopian tubes, and thoroughly informed on the psychological impact of family planning.

Project description:BackgroundStandard management for intrauterine lesions typically involves initial imaging followed by operative hysteroscopy for suspicious findings. However, the efficacy of routine outpatient hysteroscopy in women undergoing assisted reproductive technology (ART) remains uncertain due to a lack of decisive high-quality evidence. This study aimed to determine whether outpatient hysteroscopy is beneficial for infertile women who have unremarkable imaging results prior to undergoing ART.MethodsA systematic review and meta-analysis were conducted following PRISMA guidelines, incorporating data up to May 31, 2023, from databases such as PubMed, Embase, and the Cochrane Library. The primary outcome assessed was the live birth rate, with secondary outcomes including chemical pregnancy, clinical pregnancy rates, and miscarriage rates. Statistical analysis involved calculating risk ratios with 95% confidence intervals and assessing heterogeneity with the I2 statistic.ResultsThe analysis included ten randomized control trials. Receiving outpatient hysteroscopy before undergoing ART was associated with increased live birth (RR 1.22, 95% CI 1.03-1.45, I2 61%) and clinical pregnancy rate (RR 1.27 95% CI 1.10-1.47, I2 53%). Miscarriage rates did not differ significantly (RR 1.25, CI 0.90-1.76, I2 50%). Subgroup analyses did not show a significant difference in clinical pregnancy rates when comparing normal versus abnormal hysteroscopic findings (RR 1.01, CI 0.78-1.32, I2 38%). We analyzed data using both intention-to-treat and per-protocol approaches, and our findings were consistent across both analytical methods.ConclusionsOffice hysteroscopy may enhance live birth and clinical pregnancy rates in infertile women undergoing ART, even when previous imaging studies show no apparent intrauterine lesions. Treating lesions not detected by imaging may improve ART outcomes. The most commonly missed lesions are endometrial polyps, submucosal fibroids and endometritis, which are all known to affect ART success rates. The findings suggested that hysteroscopy, given its diagnostic accuracy and patient tolerability, should be considered in the management of infertility.Database registrationThe study was registered in the International Prospective Register of Systemic Review database (CRD42023476403).

Project description:BackgroundOpportunistic salpingectomy to reduce ovarian cancer incidence has become increasingly common despite the lack of randomised trials investigating its safety. In SALSTER, we tested whether salpingectomy for laparoscopic sterilisation is non-inferior to tubal occlusion regarding complications up to eight weeks postoperatively.MethodsSALSTER is a register-based randomised non-inferiority trial in which 41 gynaecological departments in Sweden participated. After being reported to The Swedish National Quality Register of Gynaecological Surgery (GynOp) for laparoscopic sterilisation, women aged <50 years received study information and could consent to participation online. If eligible, randomisation was performed by the examining/operating gynaecologist before surgery, with stratification for centre, and allocation 1:1 to salpingectomy or tubal occlusion. Blinding was attempted for patients but was impossible for surgeons. The first primary outcome, any complication up to eight weeks postoperatively, was routinely reported in GynOp through physician assessment of patient questionnaires, medical records and personal contact. Complications up to eight weeks postoperatively, a primary safety outcome, were analysed in the per-protocol population. The non-inferiority margin for the difference in the absolute risk of complications was defined as ten percentage points. Missing data were handled using multiple imputation. SALSTER was registered at ClinicalTrials.gov (NCT03860805).FindingsBetween April 4, 2019, and March 31, 2023, 539 women were randomised to salpingectomy and 527 to tubal occlusion. In the salpingectomy and tubal occlusion arms, 40 and 18 women discontinued their participation in the trial and another 26 and 10 did not receive the allocated surgery, respectively. Calculated on imputed data, any complication up to eight weeks postoperatively occurred in 8.1% (38.5/473) of patients after salpingectomy and in 6.2% (31.0/499) of patients after tubal occlusion. The risk difference was 1.9 percentage points (95% confidence interval -1.4 to 5.3).InterpretationLaparoscopic salpingectomy is non-inferior to tubal occlusion regarding complication rates up to eight weeks postoperatively.FundingThis research was funded by the Swedish Cancer Society, the Lena Wäppling foundation, the Swedish state under the ALF-agreement, Umeå University, County of Värmland, and Gothenburg Society of Medicine.

Project description:AimWomen with adenomyosis are at higher risk of endometriosis recurrence after surgery. This study was to assess if the lymphatic vessel network drained from the uterus to near organs where endometriosis foci lied.MethodsA prospective, observational study, Canadian Task Force Classification II-2, was conducted at Sacro Cuore Don Calabria Hospital, Negrar, Italy. 104 white women aged 18-43 years were enrolled consecutively for this study. All patients underwent laparoscopy for endometriosis and a tubal dye test was carried out.ResultsEvidence of dye dissemination through the uterine wall and outside the uterus was noted in 27 patients (26%) with adenomyosis as it permeated the uterine wall and a clear passage of the dye was shown in the pelvic lymphatic vessels regardless whether the tubes were unobstructed. Histological assessment of the uterine biopsies confirmed adenomyosis.ConclusionAdenomyosis is characterized by ectatic lymphatics that allow the drainage of intrauterine fluids (the dye and, perhaps, menstrual blood) at minimal intrauterine pressure from the uterine cavity though the lymphatic network to extrauterine organs. Certainly, this may not be the only explanation for endometriosis dissemination but the correlation between the routes of the dye drainage and location of endometriosis foci is highly suggestive.
