Hysteroscopic resection of the septum improves the pregnancy rate of women with unexplained infertility: a prospective controlled trial

Hysteroscopic metroplasty and its reproductive impact among the social networks: A cross-sectional analysis on video quality, reliability and creators' opinions on YouTube, TikTok and Instagram

BACKGROUND

Usefulness of hysteroscopic metroplasty to improve reproductive outcomes is controversial and debated among reproductive specialists and, consequently, patients.

METHODS

We performed a cross-sectional analysis to assess the quality, reliability, and level of misinformation in YouTube, Instagram, and TikTok videos about hysteroscopic metroplasty. Videos on each social network retrieved using "hysteroscopy" and "septate uterus" or "uterine septum" as keywords were assessed using Patient Education Materials Assessment Tool for audio-visual (PEMAT A/V) content, the modified DISCERN (mDISCERN), Global Quality Scale (GQS), Video Information and Quality Index (VIQI) and Misinformation assessment.

RESULTS

One hundred fifteen videos (47 from YouTube, 35 from TikTok, and 33 from Instagram) were included. Median PEMAT A/V Understandability and Actionability scores were 50.0 % (IQR: 0-63.3) and 20 % (IQR: 0.0-50.0). Actionability was higher YouTube relative to TikTok and Instagram (50.0 % [IQR: 0-75.0] vs. 0 % [IQR: 0-66.0]; p < 0.001 and 0 % [IQR: 0-33.0], p < 0.001), with no significant differences for Understandability. Median mDISCERN was 3 (IQR: 0-3), with higher score for YouTube compared to TikTok and Instagram (3 [IQR: 0-3] vs. 0 [IQR: 0-23], p < 0.001 and 1 [IQR 0-3.0], p < 0.001 respectively). VIQI showed low-level content (median 9; IQR: 4-19) and no differences among social media platforms. GQS was low (median 2 [IQR 1-4.5]), with no differences in subgroup analysis. Videos on YouTube (97.9 %) and TikTok (62.9 %) favored hysteroscopic metroplasty, while Instagram content was against in 63.6 % of cases (p < 0.001). While most videos were found to be either completely or partially accurate, significant differences in misinformation levels were observed across platforms, with YouTube exhibiting the lowest rate of inaccuracies compared to TikTok and Instagram. (8.5 % vs. 42.9 % and 36.4 %; p < 0.001, respectively).

CONCLUSION

Quality of social networks' videos on hysteroscopic metroplasty seems unsatisfactory, but with low levels of misinformation. YouTube and TikTok were more favorable than Instagram regarding the usefulness of metroplasty. In contrast, a favorable opinion regarding its efficacy in fertility improvement was retrieved in each social.

Reproductive performance and obstetric outcomes after hysteroscopic septum resection

PURPOSE

The aim of this retrospective cohort study was to investigate the effects of hysteroscopic uterine septum resection on the clinical pregnancy rate (CPR), live birth rate (LBR) and miscarriage rate.

MATERIALS AND METHOD(S)

Hospital records of consecutive patients who underwent hysteroscopic uterine septum resection between February 2021 and December 2022 were reviewed. They were telephoned and interviewed about their reproductive performance after surgery, and pregnancy outcomes, if achieved.

RESULTS AND CONCLUSIONS

Sixty-nine eligible patients were enrolled. Forty-one (59.4%) of these patients were referred to our clinic for otherwise unexplained infertility of at least 1 year and 28 (40.6%) for pregnancy loss. During the follow-up period, 32 patients conceived. The overall CPR was 46.4%, the LBR per woman was 36.2%, the LBR per pregnancy was 78.1% and the miscarriage rate was 12.5%. The LBRs per pregnancy were 83.3% and 71.4% in the infertility and miscarriage subgroups, respectively. The miscarriage rates per pregnancy were 0% and 28.6% in the infertility and miscarriage subgroups, respectively. Three of 6 patients whose uterine septum was incomplete but prominent became pregnant (CPR: 50.0%), and all pregnancies resulted in live birth (LBR per pregnancy:100%, LBR per woman:50%). Two patients with complete uterine septum didn't achieve pregnancy. Hysteroscopic uterine septum resection may improve the CPR, LBR and miscarriage rates in subfertile population with and without previous pregnancy loss.

Multimodal Radiographic Diagnosis of a Complex Müllerian Anomaly: A Case Report

As evidenced by the 2021 American Society for Reproductive Medicine Müllerian Anomaly Classification (ASRM MAC), there are numerous possible configurations of the female genitourinary system. Some anomalies place patients at higher risk of infertility, miscarriage, fetal malpresentation, and preterm labor. Correct characterization of Müllerian anomalies is critical for proper infertility treatment and pregnancy counseling. This case study of a 32-year-old nulliparous woman describes the radiographic modalities utilized in the diagnosis of a complex Müllerian anomaly. To characterize the Müllerian anomaly, the patient underwent a 2D transvaginal ultrasound (TVUS), saline infusion sonohysterogram (SIS) with 3D reconstruction, and second-opinion interpretation of a previous MRI. Radiographic diagnoses were conflicting among different modalities. While the saline infusion sonohysterogram suggested a bicornuate uterus, the MRI of the anomaly was interpreted as a uterine didelphys. Furthermore, TVUS and MRI indicated the presence of two cervices, while only one cervix was appreciated with SIS. Given the inconsistent interpretation of her anomaly, the patient was brought to the operating room. After direct visualization with exam and hysteroscopy, the patient was ultimately diagnosed with a uterine didelphys with a communication of endometrial cavities in the lower uterine segment, two cervices, a hypoplastic right vagina, and a longitudinal vaginal septum extending to the hymen. The patient was counseled that this anomaly is not expected to impact natural conception and would not require surgical resection. The patient went on to conceive spontaneously in the right uterine horn, with a plan for primary cesarean delivery. This case was of sufficient complexity that an accurate diagnosis was not made until physical exam and hysteroscopic visualization verified findings from MRI and ultrasonographic imaging. Appropriately describing a Müllerian anomaly according to the 2021 ASRM MAC is crucial, and multiple forms of imaging and physical examination may be necessary to accurately characterize uterine anomalies.

Evidence-based diagnosis and treatment for uterine septum: a guideline

OBJECTIVE

To provide evidence-based recommendations regarding the diagnosis and effectiveness of surgical treatment of a uterine septum.

METHODS

This guideline provides evidence-based recommendations regarding the diagnosis and effectiveness of surgical treatment of a uterine septum. This replaces the last version of the same name (Fertil Steril. 2016 Sep 1;106(3):530-40).

MAIN OUTCOME MEASURE(S)

Outcomes of interest included the impact of a septum on underlying fertility, live birth, clinical pregnancy, and obstetrical outcomes.

RESULT(S)

The literature search identified relevant studies to inform the evidence for this guideline.

CONCLUSION(S)

The treatment of uterine septa and subsequent outcomes associated with infertility, recurrent pregnancy loss, and adverse obstetrical outcomes are summarized. Resection of a septum has been shown to improve outcomes in patients with recurrent pregnancy loss and to decrease the likelihood of malpresentation. In the setting of infertility, it is recommended to use a shared decision-making model after appropriate counseling to determine whether or not to proceed with septum resection.

Fertility, pregnancy and perioperative outcomes after operative hysteroscopy for uterine septum: a network meta-analysis

INTRODUCTION

Septate uterus is a congenital malformation associated with adverse reproductive and pregnancy outcomes. It remains controversial whether hysteroscopic septoplasty should be recommended for the treatment of septate uterus, and it is also unclear if different hysteroscopic methods have more favorable outcomes. This study aims to compare the available hysteroscopic techniques of septoplasty for fertility, reproductive, and perioperative outcomes.

METHODS

This systematic review and meta-analysis was conducted following PRISMA guidelines. We searched Medline, Scopus, and Cochrane databases up to April 2023 without language restrictions. Eligible studies had to compare two or more different methods of hysteroscopic septoplasty in women with septate uterus and report on fertility and pregnancy outcomes after a follow-up. Perioperative outcomes were also examined. Data extraction was performed by two independent reviewers using a standardized form. Risk of bias was assessed using the Newcastle-Ottawa Quality Assessment Form and Revised Cochrane risk-of-bias tool (RoB 2).

RESULTS

Out of 561 studies identified, 9 were included in the systematic review and meta-analysis. The comparison of different hysteroscopic septoplasty techniques based on the energy used showed higher pregnancy rates after mechanical septoplasty in comparison to electrosurgery, while miscarriage and live birth rates were comparable. Laser vs. electrosurgery and mechanical techniques of septoplasty had comparable pregnancy, miscarriage, and live birth rates. The network meta-analysis after comparing every different method used showed significantly higher clinical pregnancy rate in scissor group in comparison to resectoscope. No significant differences were found among the techniques regarding miscarriage rate and live birth rate.

CONCLUSION

In summary, this systematic review and network meta-analysis suggests that hysteroscopic septoplasty with scissors is associated with higher pregnancy rates compared to resectoscope. However, the limited evidence available and small sample sizes in the included studies indicate that these findings should be interpreted with caution. Further studies are required to determine the effectiveness of various hysteroscopic techniques and guide clinical decision-making in the management of this condition.

Comparison of clinical outcomes and second-look hysteroscopy of the complete and incomplete septate uterus after hysteroscopic septoplasty

PURPOSE

Septate uterus is the most common congenital uterine malformation. This retrospective cohort study compared clinical outcomes and second-look hysteroscopy findings in patients with complete and incomplete septate uteri after septoplasty.

METHODS

We reviewed the medical records of patients with a septate uterus who underwent hysteroscopic septoplasty and second-look hysteroscopy at the West China Second University Hospital between September 2013 and September 2021. Information regarding pregnancy outcomes was collected through telephone interviews. The independent samples t-test, Mann-Whitney U test, Pearson's chi-square test, and Fisher's exact test were used to explore the differences between the complete and incomplete septate uterus groups.

RESULTS

A total of 64 patients were enrolled in this study. There was no significant difference in intrauterine adhesion (IUA) rates (16.7% and 32.1%), pregnancy rates (44.1% and 42.9%), term delivery rates (35.3% and 32.1%), premature delivery rates (2.9% and 0), placenta previa rates (2.9% and 3.6%), placenta implantation/adhesion rates (5.9% and 3.6%), and premature rupture of membranes rates (2.9% and 0) between the complete and the incomplete group after hysteroscopic septoplasty (P > 0.05). Endometrial polyps in the septate uterus were common, with an incidence of 33.3% and 25% in the complete and incomplete groups, respectively (P > 0.05).

CONCLUSION

The pregnancy outcomes of complete and incomplete septate uteri after hysteroscopic septoplasty were similar. There was no statistical difference in IUAs after surgery. Different treatment strategies may not be required for complete or incomplete septate uteri.

Reproductive outcomes of oocyte donation in patients with uterine Müllerian anomalies

OBJECTIVE

To evaluate live-birth rates per embryo transfer in patients with uterine Müllerian anomalies (UMAs). Secondary objectives were to compare reproductive outcomes between the normal uterus group, the different UMA types, and UMA subgroups with and without required surgery.

DESIGN

This retrospective study compared two cohorts, one with UMAs and other with normal uteri of our oocyte donation program at 12 Instituto Valenciano De Infertilidad/Reproductive Medicine Associates University affiliated clinics from January 2000 to 2020. The oocyte donation reduces confounding because of differences in embryo quality. The primary outcome was the live-birth rate per embryo transfer. Secondary outcomes included the rates of implantation, clinical pregnancy, miscarriage, and ongoing pregnancy. We calculated odds ratios with 95% confidence intervals.

PATIENTS

Infertile women undergoing oocyte donation with UMAs.

INTERVENTION

None.

MAIN OUTCOME MEASURES

The rates of implantation, clinical pregnancy, miscarriage, ongoing pregnancy, and live birth.

RESULTS

We analyzed 58,337 cycles of oocyte donation: 57,869 patients had no uterine malformation, and 468 women had UMAs. Compared with patients with normal uteri, patients with UMAs had lower rates of live births (36.67% [32.84-40.65] vs. 38.1% [95% confidence intervals {CI}: 37.82-38.42]) and ongoing pregnancy (39.74% [35.93-43.66] vs. 41.5% [41.24-41.83]). The miscarriage rate was higher in patients with UMAs (19.5% [16.55-22.85] vs. 16.6% [16.47-16.92]). Specifically, patients with a unicornuate uterus (n=29) had lower rates of implantation (24.07% [13.49-37.64] vs. 42.85% [95% CI: 42.6-43.09]), pregnancy (41.86% [27.01-57.87] vs. 59.51% [59.22-59.81]), ongoing pregnancy (16.67% [6.97-31.36] vs. 41.54% [41.24-41.83]), and live births (16.67% [6.97-31.36] vs. 38.12% [37.83-38.42]). In addition, patients with a partial septate uterus (n=91) had a higher miscarriage rate (26.50% [18.44-34.89] vs. 16.7% [16.47-16.92]). Compared with the normal uterus group, the live-birth rates were lower in the UMA without surgery group (33.09% [27.59-38.96] vs. 38.12% [37.83-38.42]).

CONCLUSION

Among patients who received embryos derived from donated oocytes, live birth and ongoing pregnancy rates were lower in patients with UMAs compared with patients with normal uteri. A higher miscarriage rate was found in patients with UMAs. Patients with a unicornuate uterus had worse reproductive outcomes. Our results show that the uterus is less competent in patients with UMAs.

Septum Resection Prior to In Vitro Fertilization-Embryo Transfer: A Retrospective Controlled Study

OBJECTIVES

To investigate the effectiveness of surgery for septate uterus in infertile patients before in vitro fertilization-embryo transfer (IVF-ET).

METHODS

The data of 937 infertile patients with septate uterus and achieved singleton pregnancy after IVF-ET from January 2014 to December 2015 were retrospectively analyzed. Thousand five hundred seventy-eight infertile patients with a normal uterus who achieved singleton pregnancy during the same period were selected as the control group. Patients with septate uterus were divided into two groups according to whether the septum was resected. The pregnancy and perinatal outcomes of the surgical group and the nonsurgical group were compared with the control group. The secondary infertility patients who were surgically corrected septa were also chosen as self-controls and an analysis was performed on their fertility outcomes pre- and post-surgery.

RESULTS

Compared with the control group, the surgical group had increased rates of early miscarriage, preterm delivery, and low birthweight and a significantly reduced live birth rate (P < .05). The outcomes of the nonsurgical and control groups were similar. Using secondary infertility patients who were surgically corrected septa as self-controls, after surgery, the rates of miscarriage and ectopic pregnancy were significantly lower and the live birth rate was significantly higher (P ≤ .001); however, perinatal mortality was not significantly different before and after surgery.

CONCLUSIONS

Patients with a septum depth greater than 10 mm or 5-10 mm associated with a history of unexplained recurrent miscarriage, IVF failure, or infertility might benefit from resection of the uterine septum with hysteroscopic metroplasty.

Efficacy of hysteroscopic septum resection in infertile women: a single center experience

INTRODUCTION

We aimed to reveal the effectiveness of hysteroscopic septum resection on the reproductive outcomes of infertile patients.

MATERIAL AND METHODS

We included 46 infertile women who underwent hysteroscopic septum resection of septate uterus (complete: group 1, n = 21; incomplete: group 2, n = 25). Only patients with a septate uterus as the cause of infertility were included in the study. Patients' age, body mass, duration of infertility, type of infertility, duration of surgery, surgical complications, remnant septa, and postoperative reproductive results were recorded.

RESULTS

Preoperative abortion was found to be nine (42.9%) in group 1 and 15 (60.0%) in group 2. In the postoperative control HSG, remnant septa was found to be significantly higher in group 1 compared to group 2 (three patients or 14.3% and 0%, respectively). Pregnancy was detected in 13 patients (61.9%) in group 1 and 18 patients (72%) in group 2 at the postsurgical follow-up. Abortion occurred for two patients (9.5%) in group 1 and three patients (12%) in group 2.

CONCLUSION

We obtained positive growth results after hysteroscopic septum resection in both the complete and incomplete cases. However, we found that the duration of surgery was prolonged and the rate of remnant septa increased in cases with a complete septum.

Complete Uterine Septum, Double Cervix and Vaginal Septum (U2b C2 V1): Hysteroscopic Management and Fertility Outcomes-A Systematic Review

BACKGROUND

complete uterine septum, double cervix and vaginal septum is a rare complex Müllerian anomaly affecting patients' quality of life in terms of fertility and pelvic pain. The aim of our review is to gather the studies concerning the diagnosis and treatment this complex malformation and to describe the related fertility outcomes.

METHODS

this study was conducted in 2022, according to the criteria of Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and the protocol was submitted to the International Prospective Register for Systematic Reviews (PROSPERO). PubMed, Scopus and Web of Science electronic databases were searched to find eligible articles. In total, 538 articles were identified through literature research. A total of ten articles satisfied the eligibility criteria and were included in the systematic review.

RESULTS

86 affected women were evaluated, and 71 of them were treated. Almost all patients included in our research presented with primary infertility or with a history of recurrent miscarriages; half of all patients also reported dyspareunia. After surgical treatment, 47 pregnancies were achieved: 41 live birth and ongoing pregnancies and six spontaneous miscarriages occurred; a significantly lower miscarriage rate was reported after surgical treatment.

CONCLUSION

hysteroscopic treatment of U2b C2 V1 anomaly can be safely performed, leading to favorable fertility outcomes, measured as the achievement of pregnancy and a reduction in miscarriage rate.

Does Hysteroscopic Dissection of Partial Uterine Septum Represent a Risk Factor for Placental Abnormalities in Subsequent Pregnancy Compared with Controls Undergoing Other Hysteroscopic Surgery? Results from a Large Case-Control Analysis

BACKGROUND

Hysteroscopic septum dissection (HSD) is thought to improve fertility and pregnancy outcomes. However, the available literature suggests that uterine surgery can cause placental abnormalities in subsequent pregnancies.

METHODS

A case-control study was performed at the University Medical Center of Ljubljana, Department of Human Reproduction, from 1 January 2016 to 31 December 2018. The primary outcome was the association between HSD and the occurrence of placental abnormalities. We included women who underwent HSD due to infertility. Age-matched women who underwent hysteroscopic surgery for other issues were considered as controls. In addition, we divided the groups according to conception method. Only singleton pregnancies and first delivery were considered.

RESULTS

A total of 1286 women (746 who underwent HSD and 540 controls) were included in the analysis. HSD had no influence on placental abnormalities since the ratio was comparable regardless of the method of conception (113/746 vs. 69/540; p = 0.515). Infertile women who conceived naturally after HSD had a normal placentation rate comparable to women who did not undergo HSD (380/427 vs. 280/312; p = 0.2104). The rate of placental abnormalities in women who achieved pregnancy with IVF/ICSI procedures following HSD was comparable to that of women who did not undergo HSD (52/319 vs. 33/228; p = 0.5478). Placenta previa occurred significantly more often in infertile women without HSD after IVF/ICSI compared to natural conception (2/312 vs. 7/228; p = 0.0401).

CONCLUSIONS

HSD was not associated with higher rate of placental abnormalities in the first singleton pregnancy compared with other hysteroscopic procedures. A higher rate of placenta previa in pregnancies following IVF/ICSI procedures, which was shown by our research, is corroborated by previous research findings.

Uterine Septum with or without Hysteroscopic Metroplasty: Impact on Fertility and Obstetrical Outcomes-A Systematic Review and Meta-Analysis of Observational Research

Objective: we performed a systematic review/meta-analysis to evaluate the impact of septate uterus and hysteroscopic metroplasty on pregnancy rate-(PR), live birth rate-(LBR), spontaneous abortion-(SA) and preterm labor (PL) in infertile/recurrent miscarriage-(RM) patients. Data sources: a literature search of relevant papers was conducted using electronic bibliographic databases (Medline, Scopus, Embase, Science direct). Study eligibility criteria: we included in this meta-analysis all types of observational studies that evaluated the clinical impact of the uterine septum and its resection (hysteroscopic metroplasty) on reproductive and obstetrics outcomes. The population included were patients with a diagnosis of infertility or recurrent pregnancy loss. Study appraisal and synthesis methods: outcomes were evaluated according to three subgroups: (i) Women with untreated uterine septum versus women without septum (controls); (ii) Women with treated uterine septum versus women with untreated septum (controls); (iii) Women before and after septum removal. Odds ratios (OR) with 95% confidence intervals (CI) were calculated for the outcome measures. A p-value < 0.05 was considered statistically significant. Subgroup analysis was performed according to the depth of the septum. Sources of heterogeneity were explored by meta-regression analysis according to specific features: assisted reproductive technology/spontaneous conception, study design and quality of papers included Results: data from 38 studies were extracted. (i) septum versus no septum: a lower PR and LBR were associated with septate uterus vs. controls (OR 0.45, 95% CI 0.27−0.76; p < 0.0001; and OR 0.21, 95% CI 0.12−0.39; p < 0.0001); a higher proportion of SA and PL was associated with septate uterus vs. controls (OR 4.29, 95% CI 2.90−6.36; p < 0.0001; OR 2.56, 95% CI 1.52−4.31; p = 0.0004). (ii) treated versus untreated septum: PR and PL were not different in removed vs. unremoved septum(OR 1.10, 95% CI 0.49−2.49; p = 0.82 and OR 0.81, 95% CI 0.35−1.86; p = 0.62); a lower proportion of SA was associated with removed vs. unremoved septum (OR 0.47, 95% CI 0.21−1.04; p = 0.001); (iii) before-after septum removal: the proportion of LBR was higher after the removal of septum (OR 49.58, 95% CI 29.93−82.13; p < 0.0001) and the proportion of SA and PL was lower after the removal of the septum (OR 0.02, 95% CI 0.02−0.04; p < 0.000 and OR 0.05, 95% CI 0.03−0.08; p < 0.0001) Conclusions: the results show the detrimental effect of the uterine septum on PR, LBR, SA and PL. Its treatment reduces the rate of SA.

Uterine septum and reproductive outcome. From diagnosis to treatment. How, why, when?

Background: Septate uterus is a benign congenital malformation and represents the most common uterine anomaly in women with poor reproductive outcome. Objectives: To review the available scientific data concerning the biological context of the intrauterine septum and the association with poor reproductive outcome, the best methods for diagnosis and treatment. Materials and methods: From July 2020 to October 2020, we searched for relevant free full text articles in PubMed, written in English, and published from the 1st of January 2000 to 31st of July 2020. Main outcome measures: Association of the pathophysiology of septate uterus with poor reproductive outcome, evaluation of the different classification systems, the accuracy of diagnostic methods and the efficacy of the available treatment options. Results: 259 articles were screened, and 22 articles were finally included in our study. Many theories regarding the pathophysiology of this congenital anomaly and its’ association with reproductive problems have been proposed along the recent decades. Combination of diagnostic methods should be used to avoid misclassification of this congenital anomaly. Conclusions: Lack of uniformity in the different classification systems makes the diagnosis of septate uterus challenging as there is no universally accepted definition. Data regarding the reproductive outcome of women with septate uterus are still limited, thus recommendations regarding optimal treatment of these women are biased. What is new? According to new insights regarding the pathophysiology of the uterine septum, differences in the underlying embryological defects are associated with changes in the histological composition and vascularisation of septa, as well as in clinical significance.

Second look hysteroscopy following hysteroscopic septum resection improves reproductive outcomes in patients undergoing ICSI

The aim of this study was to compare the reproductive outcomes between infertile women who underwent hysteroscopic uterine septum resection and those who required a second look hysteroscopy due to residual septum prior to intracytoplasmic sperm injection (ICSI) cycles with selective single 'Grade A' embryo transfer (ET). All second look hysteroscopies were performed due to partial remnant septum in a control three dimensional transvaginal ultrasonography (3D TVUSG) after the first hysteroscopic resection. Miscarriage and biochemical pregnancy rates were not different between the groups while clinical pregnancy and live birth rates were significantly higher in Group 2 than in Group 1. Second look hysteroscopic metroplasty performed to restore remnant septum significantly improves live birth rate as well as clinical pregnancy rates while it appears not to alleviate abortion and biochemical pregnancy rates in women undergoing ICSI-ET.IMPACT STATEMENTWhat is already known on this subject? The effect of hysteroscopic septum resection on reproductive outcomes in IVF treatment in infertile patients with uterine septum is not clearly known.What do the results of this study add? With the selective single ET strategy, complete or partial hysteroscopic correction of the uterine septum before ICSI and subsequent resection of the residual septum with control hysteroscopy significantly increases the live birth rates in the infertile population.What are the implications of these findings for clinical practice and/or further research? In the group of infertile patients with uterine septum, second control hysteroscopy should be performed 1 month later for residual septum or adhesions after hysteroscopic septum resection performed once.

Effects of Septum Resection for Secondary Infertility on Subsequent Reproductive Outcomes of in vitro Fertilization-Intracytoplasmic Sperm Injection

OBJECTIVE

To assess the effect of uterine septum resection on reproductive outcomes of in vitro fertilization (IVF) / intracytoplasmic sperm injection (ICSI) in patients with secondary infertility complicated with uterine septum.

METHODS

A retrospective cohort study included 269 patients. Surgical group included 169 patients with secondary infertility complicated with uterine septum, who underwent 252 embryo-transfer (ET) cycles following septum resection. Control group consisted of 100 patients with secondary infertility and uterine septum, who underwent 178 ET cycles. Cumulative pregnancy rate and cumulative live birth rate after one complete assisted reproductive technology (ART) cycle were the primary outcomes.

RESULTS

The results showed that the cumulative pregnancy rate was higher in the surgery group, and statistically significant difference was observed in the cumulative pregnancy rate between the two groups (71.0 vs. 59%, P = 0.044). In fresh ET cycle, no statistically significant difference between the two groups was evident (54.9 vs. 40.6%, P = 0.061). Statistical analysis of other results of the fresh ET cycle did not differ significantly between the two groups. In terms of frozen embryo transfer (FET) cycle outcomes, the clinical pregnancy rate and delivery rate in surgery group were 52.7 and 38.2%, respectively, which were significantly higher than those in the control group (38.2 and 22.5%, respectively) (P = 0.028 and P = 0.011).

CONCLUSION

The reproductive outcomes of IVF/ICSI after septum resection in patients with secondary infertility were better than that in the untreated group, suggesting that uterine septum resection can be performed in patients with uterine septum combined with infertility to improve their reproductive outcomes.

Fertility and pregnancy outcomes following hysteroscopic metroplasty of uterine septa

The septate uterus is still a matter of debate and discussion today in different medical forums. The controversy is divided between 2 different quite divergent opinions: on the one hand, those who promote its surgical correction; and on the other hand, those who advocate expectant management with no recommended surgical intervention. It is extremely difficult to determine the association between septum and infertility. Infertility is a multifactorial condition; furthermore, the mechanism by which the septate uterus is associated with infertility is still unknown, although the most probable causes seem to be related to implantation alterations. There is lack of high-quality randomized controlled studies with an adequate number of patients demonstrating the efficacy of the surgical treatment of patients with septated uterus. However, the limited available data based on observational studies, support minimally-invasive treatment using hysteroscopy as the method of choice for the treatment of patients with septated uterus and history of infertility or poor obstetrical outcomes.

A review of the pathophysiology of recurrent implantation failure

Implantation is a critical step in human reproduction. The success of this step is dependent on a competent blastocyst, receptive endometrium, and successful cross talk between the embryonic and maternal interfaces. Recurrent implantation failure is the lack of implantation after the transfer of several embryo transfers. As the success of in vitro fertilization has increased and failures have become more unacceptable for patients and providers, the literature on recurrent implantation failure has increased. While this clinical phenomenon is often encountered, there is not a universally agreed-on definition-something addressed in an earlier portion of this Views and Reviews. Implantation failure can result from several different factors. In this review, we discuss factors including the maternal immune system, genetics of the embryo and parents, anatomic factors, hematologic factors, reproductive tract microbiome, and endocrine milieu, which factors into embryo and endometrial synchrony. These potential causes are at various stages of research and not all have clear implications or immediately apparent treatment.

Daily practice management of septate uterus: reproductive outcome after septoplasty

Background

Septate uterus is the most common uterine malformation found in women presenting poor reproductive history. Hysteroscopic septoplasty (HS) restores the uterine anatomy in a safe procedure.

Objectives

The goal of our study is to determine the reproductive outcomes after HS of symptomatic septate uterus.

Materials and Methods

In a retrospective observational single centre study the reproductive outcomes and complications after HS were evaluated in 31 women with symptomatic septate uterus. The patients were separated into two groups according to the symptoms - infertility or recurrent pregnancy loss (RPL).

Main outcome measures

were the pregnancy and live birth rate and secondarily the complication rate. Furthermore, the results were analysed depending on the need of assisted reproductive techniques (ART).

Results

The treatment has resulted in an overall pregnancy rate of 71% for both groups. The spontaneous pregnancy rate is 45% and 8 pregnancies resulted from ART (26%). The overall first live birth rate is 51.6%. A decrease has been noticed in the miscarriage rate from 95.24% to 24% (p<0.001) in the overall population.

Conclusions

In patients with a symptomatic septate uterus hysteroscopic septoplasty is a safe and effective procedure. The favourable results pointing out the benefits of surgery on the reproductive outcomes as well as the relatively simple and safe technique of HS make the intervention attractive.

Transcorporal septal dissection using the balloon technique in complete uterine septums, pre- and postoperative results. A follow up from 2007 to 2020

OBJECTIVE

The aim of the study is to show the pre- and postoperative results of transcorporal septal dissection using the balloon technique in complete uterine septums, which is a rare pathology.

STUDY DESIGN

It is a retrospective analysis. In this study 21 patients with a complete uterine septum were included. All patient underwent the transcorporal septal dissection using the balloon technique. Data analysis was based on patient history, surgical reports and telephone contact with the patients and supervising gynecologists.

RESULTS

73% patients with a current desire to become pregnant managed to do so and 75% of them were able to give birth on time. One patient was pregnant at the time of the analysis. In 17 patients the results of the control hysteroscopy were available. In eight patients (47%) a normal cavity was found. In nine cases (53%) a residual septum of 1-2 cm was found, so that an operative hysteroscopy with a residual septum dissection was performed. The operative time was average 30.6 min in the group without laparoscopy and 56.8 min in the group with laparoscopy.

CONCLUSION

The transcorporal septum dissection using the balloon technique is a safe method with a good fertility outcome and requires an experienced surgeon.

Successful Vaginal Delivery after External Cephalic Version in a Woman with a Large Partial Uterine Septum

Septate uteri have been associated with adverse pregnancy outcomes including spontaneous abortion, preterm delivery, and malpresentation. It is unclear if uterine septa are associated with infertility. Although some studies have shown improved pregnancy outcomes after septum resection, indications for resection are not well established. We describe a case of a woman with a large partial uterine septum diagnosed during workup for infertility who conceived without septum resection. Both of her subsequent pregnancies were initially breech presentations for which the patient underwent external cephalic version followed by full-term vaginal deliveries. This case adds evidence that an unresected uterine septum should not be considered a contraindication to external cephalic version.

Hysteroscopy as An Investigational Operative Procedure in Primary and Secondary Infertility: A Systematic Review

Background

The aim of this study is to review current indications to diagnostic and/or operative hysteroscopy in primary and secondary infertility, as well as to determine its efficacy in improving fertility.

Materials and Methods

We gathered available evidence about the role of hysteroscopy in the management of vari- ous infertility conditions. Literature from 2000 to 2020 that pertained to this topic were retrieved and appropriately selected.

Results

Hysteroscopy does not appear as a first line diagnostic procedure for every clinical scenario. However, its di- agnostic sensitivity and specificity in assessing intrauterine pathology is superior to all other non-invasive techniques, such as saline infusion/gel instillation sonography (SIS/GIS), transvaginal sonography (TVS) and hysterosalpingog- raphy (HSG). Hysteroscopy allows not only a satisfactory evaluation of the uterine cavity but also, the eventual treat- ment of endocavitary pathologies that may affect fertility both in spontaneous and assisted reproductive technology (ART) cycles.

Conclusion

Hysteroscopy, due to its diagnostic and therapeutic potential, should be regarded as a necessary step in infertility management. However, in case of suspected uterine malformation, hysteroscopy should be integrated with other tests [three-dimensional (3D) ultrasound or magnetic resonance imaging (MRI)] for diagnostic confirmation.

Bedeutung der Fertilitätschirurgie bei Kinderwunsch

Die Bedeutung der Fertilitätschirurgie bei Kinderwunsch kann vielfach aufgrund fehlender eigener Erfahrung während der Facharztweiterbildung nicht erfasst werden, da nur an wenigen Zentren eine spezifische operative Ausbildung erfolgt. Neben der Abklärung anatomischer Fehlbildungen mittels Hysteroskopie bzw. Laparoskopie gehört die operative Myom- und Endometriosebehandlung zu den Standardverfahren der Fertilitätschirurgie. Hier ist die Erfahrung der Reproduktionsmediziner gefragt, damit unter maximaler Schonung der Ovarreserve ein bestmöglichstes Ergebnis hinsichtlich Endometriosesanierung bzw. Myomenukleation erreicht wird. Die Abklärung der Tubendurchgängigkeit mit Chromopertubation ist nach wie vor Goldstandard, auch wenn im ambulanten Sektor vorwiegend nichtoperative Verfahren zum Einsatz kommen. Die diagnostische und gegebenenfalls operative Hysteroskopie dient der Beurteilung des Endometriums und erlaubt den Ausschluss von Entzündungsprozessen oder dem Vorliegen von Polypen.

Preconception Evaluation Before In Vitro Fertilization

Importance

Infertility poses a substantial public health problem for women of reproductive age, in the United States and globally. Infertility can be overcome with a variety of emerging assisted reproductive technologies (ARTs). In vitro fertilization (IVF) currently represents the most commonly utilized method of ART and is typically associated with the highest clinical pregnancy rate and live birth rate compared with other infertility treatment options. However, proper preconception evaluation and counseling is paramount for optimizing IVF and pregnancy outcomes.

Objective

This article aims to outline current guidelines and recommendations for comprehensive preconception evaluation before initiation of IVF.

Evidence Acquisition

Articles were obtained from PubMed, ACOG committee opinions 781 and 762, and relevant textbook chapters.

Results

A variety of recommendations and best practices exist for optimally managing patients seeking IVF. Special attention must be paid to the workup of certain patient populations, such as those with age older than 35 years, uterine abnormalities, comorbidities (especially hypertension, diabetes, and thrombophilias), and obesity. In addition, many lifestyle factors must be addressed before IVF initiation, such as smoking, illicit drug use, and inadequate nutrition. Preconception counseling and expectation management is key to optimizing pregnancy outcome.

Conclusion and Relevance

A myriad of patient and environmental factors impact the potential success rates of IVF in treating infertility. Providers must be equipped to provide data-driven, patient-centered counseling before initiation of IVF.

Reproductive Performance Following Hysteroscopic Surgery for Uterine Septum: Results from a Single Surgeon Data

Uterine septum can negatively affect reproductive outcomes in women. Based on evidence from retrospective observational studies, hysteroscopic incision has been considered a solution to improve reproductive performance, however there has been recent controversy on the need for surgery for uterine septum. High quality evidence from prospective studies is still lacking, and until it is available, experts are encouraged to publish their data. We are therefore presenting our data that involves analysis of the patient characteristics, surgical approach and long-term reproductive outcomes of women who received treatment for uterine septum under the care of a single surgeon. This includes all women (99) who underwent hysteroscopic surgery for uterine septum between January 2001 and December 2019. Of those 99 women treated for intrauterine septum who were trying to conceive, 91.4% (64/70) achieved pregnancy, 78.6% (55/70) had live births and 8.6% (6/70) had miscarriages. No statistically significant difference was found in the live birth rates when data was analyzed in subgroups based on age, reason for referral/aetiology and severity of pathology. Our study results support the view that surgical treatment of uterine septa is beneficial in improving reproductive outcomes.

Uterine rupture in pregnancy after hysteroscopic septum resection: a 20-year retrospective analysis

INTRODUCTION

In this study, we reviewed the cases of uterine rupture in our setting, identified which of them had previously undergone hysteroscopic septum resection (HSR), and evaluated the main clinical characteristics for each case.

MATERIAL AND METHODS

We retrospectively analyzed (ClinicalTrial ID: NCT04449640) the delivery outcomes from the National Perinatal Information System of the National Institute of Public Health of the Republic of Slovenia of the last 20 years (1 January 1999 - 31 December 2019) and cross-linked the patients with surgical data from our electronic database. We collected baseline characteristics, surgical details and obstetrical outcomes. We excluded women who had undergone previous myomectomy or cesarean section (CS) and described the clinical course of each case since no statistical analysis was performed.

RESULTS

We found four patients who had uterine rupture in pregnancy after HSR. Median time to pregnancy was 17 months (range 1-60), all the women underwent CS and fetal-maternal outcomes were acceptable in half of the cases. Symptoms were nonspecific and included pain, fetal distress and vaginal bleeding.

CONCLUSION

Uterine rupture in pregnancy after a previous HSR is a very rare, but life-threatening event. Prompt diagnosis can ensure successful management and avoid adverse maternal-fetal outcomes.

Hysteroscopy and female infertility: a fresh look to a busy corner

Hysteroscopy has evolved from the traditional art of examining the uterine cavity for diagnostic purposes to an invaluable modality to concomitantly diagnose and (see and) treat a multitude of intrauterine pathologies, especially in the field and clinics specialising in female reproduction. This article reviews the literature on the most common cervical, endometrial, uterine and tubal pathologies such as chronic endometritis, endometrial polyps, adenomyosis, endometriosis, endometrial atrophy, adhesions, endometrial hyperplasia, cancer, and uterine malformations. The aim is to determine the efficiency of hysteroscopy compared with other available techniques as a diagnostic and treatment tool and its association with the success of in vitro fertilisation procedures. Although hysteroscopy requires an experienced operator for optimal results and is still an invasive procedure, it has the unique advantage of combining great diagnostic and treatment opportunities before and after ART procedures. In conclusion, hysteroscopy should be recommended as a first-line procedure in all cases with female infertility, and a special effort should be made for its implementation in the development of new high-tech procedures for identification and treatment infertility-associated conditions.

Effect of hysteroscopic septum resection on preterm delivery rate in singleton pregnancies

INTRODUCTION

Uterine septum is the most common uterine anomaly and is often found during the work-up in primary infertile women. In this study, we aimed to evaluate the potential effect of hysteroscopic septum resection (HSR) on preterm delivery (PTD) in primary infertile women who had singleton pregnancies.

MATERIAL AND METHODS

We analyzed 420 singleton pregnancies after primary infertility treatment and compared the PTD rates in women who underwent previous HSR (cases) and women who did not undergo previous operative hysteroscopy or cervical dilation (controls), regardless of the modality of conception (spontaneous or by in vitro fertilization).

RESULTS

We did not find significant differences between cases and controls for the incidence of overall PTD rate (p = .237), PTD before 32 gestational weeks (p = .848), and between 32 and 37 gestational weeks (p = .324), premature rupture of membranes (p = .419), and neonatal birth weight (p = .129). Overall, the risk of spontaneous PTD <37 gestational weeks after HSR was not found to be significantly higher compared to controls (RR 1.29, 0.61-2.73 95% CI; p = .561).

CONCLUSION

According to our results, previous HSR could be not considered a risk factor for PTD in singleton pregnancies, regardless of the modality of conception (spontaneous or by in vitro fertilization).

Reproductive outcome of a complete septate uterus after hysteroscopic metroplasty

Objective

This study aimed to evaluate the reproductive outcomes of patients who underwent hysteroscopic metroplasty for correction of a complete septate uterus.

Methods

The study population comprised 92 women with complete septate uteri. Hysteroscopic metroplasty and laparoscopy were performed simultaneously in these patients. The postoperative reproductive outcome of each patient was evaluated.

Results

In the primary infertility group, there were 32 (40%) pregnancies. In the abortion group, the number of miscarriages decreased from 68 (94.44%) to 5 (10.42%), while the number of live births increased from 1 (1.39%) to 42 (87.50%) after resection compared with before resection. The cumulative probability of pregnancy and that of live-birth pregnancy in the abortion group were significantly higher than those in the primary infertility group after surgery. Furthermore, resection of the cervical septum resulted in a significantly higher cumulative probability of live birth compared with preservation of the cervical septum.

Conclusion

Hysteroscopic uterine metroplasty may improve the reproductive performance of a septate uterus. Resection of the cervical septum may increase the probability of a live-birth pregnancy for patients with a cervical septum, and this procedure could be recommended for cases of a complete uterine septum.

Reproductive surgery and in vitro fertilization: the future reevaluated

A crisis is occurring in that reproductive endocrinologists are not doing the surgeries that are a part of their discipline. We list those procedures as a blueprint for training reproductive endocrinologists.

[Impact of luteal phase support by human chorionic gonadotropin (hCG) in intrauterine inseminations]

OBJECTIVES

The objective of our study is to evaluate the impact of luteal phase support by hCG in intrauterine inseminations preceded by ovarian gonadotropin stimulation.

METHODS

A retrospective study was conducted at the CHU of Nice between March 1, 2016 and October 31, 2017. During this period, 300 intrauterine inseminations were included in data analysis. Ovarian stimulation was performed by gonadotropins and a GnRH antagonist was added, if needed. Following a modification of standard operative procedure in the department, patients who performed an intrauterine insemination from December 1, 2016 received luteal phase support with two injections of hCG 1500 IU, performed at three days of interval. Pregnancy and ovarian hyperstimulation syndrome were the primary and secondary study endpoints, respectively.

RESULTS

Out of 300 inseminations included in the analysis, 144 were performed with luteal phase support and 156 without support. No statistically significant difference in pregnancy rate was observed between these two groups (19.4% of pregnancy in the luteal phase support group and 15.38% in the group without luteal phase support, P=0.353). No ovarian hyperstimulation syndrome occurred over the course of the study.

CONCLUSION

Our study shows a slight improvement of pregnancy rate in the group subjected to luteal phase support by hCG after intrauterine insemination, but the benefit was not significant. A randomised prospective study based on a large cohort could help to assess the effect of luteal phase support during intrauterine inseminations.

Fertility and pregnancy outcomes following hysteroscopic metroplasty of different sized uterine septa: A retrospective cohort study protocol

Different sizes of uterine septum between infertile women and patients with abortions may have a clinical relevance in reproductive performance after surgery. This study aimed to assess if the fecundity of women after surgical correction of the uterine septum is associated with septum size.A retrospective, single-center, cohort study was conducted in Peking Union Medical College Hospital using patients aged between 21 and 37 years. Hysteroscopic metroplasty was performed on 121 patients with a uterine septum. The septum size was assessed by ultrasonography and hysteroscopy. The subjects were divided into 3 groups: Group A consisted of 35 women with complete uterine septum (mean ± standard deviation (SD) age 28.29 ± 3.53; group B consisted of 48 women with uterine septum >2.5 cm (mean ± SD age 28.85 ± 3.63); and group C consisted of 48 women with uterine septum ≤2.5 cm (mean ± SD age 28.79 ± 3.74). Age and body mass index (BMI) were not significantly different among the 3 groups.No serious hysteroscopic complications occurred. However, uterine septa were observed in 4 cases after surgery and 6 cases of intrauterine adhesions were observed after long-term follow-up. The abortion rate decreased, and term delivery rate increased significantly in the 3 groups after hysteroscopic metroplasty. The infertility rate was significantly lower in group C after surgery. However, no significant difference was observed in the infertility rate between groups A and B. The recurrent abortion rate was significantly lower in group A than in groups B and C before surgery. After surgery, the infertility rate was significantly higher in group A than in group B (28.57% and 10.53%, respectively; P = .048). After at least 12-months of follow-up, the pregnancy rate in group A was significantly lower than that in group C (71.43% and 89.47%, respectively; P = .048).Uterine septum resection improves obstetrical outcomes. After surgery, the infertility rate was significantly higher in patients with complete uterine septum than in those with a large partial uterine septum, and the pregnancy rate in patients with complete uterine septum was lower than that in the patients with a small partial uterine septum.

Surgical management of congenital uterine anomalies (including indications and surgical techniques)

The prevalence of congenital uterine anomalies (CUA) is reported to be 4.3-6.7% in the general population, 3.4%-8% in the infertile population, and 12.6-18.2% of those with recurrent miscarriages. They are the result of abnormal formation, differentiation, and fusion of the Müllerian or paramesonephric ducts during fetal life. To date, various classification systems have been proposed for the categorization of CUA, but the recently introduced ESHRE/ESGE classification seems to be a new, clear, and systematic categorization, which could be the basis for clinicians to rely on when they refer to CUA and their clinical impact either generally or concerning pregnancy outcomes. CUA are apparently related to an impaired reproductive outcome, while their exact clinical impact as well as the effectiveness of their treatment remain considered controversial. Surgery is indicated in women presenting with symptoms related to specific uterine anomalies, especially in those with fertility problems. In this review, indications, surgical techniques for the repair of CUA according to their classification, and fertility and pregnancy outcomes before and after surgery will be thoroughly reviewed.

Hysteroscopy for treating subfertility associated with suspected major uterine cavity abnormalities

BACKGROUND

Observational studies suggest higher pregnancy rates after the hysteroscopic removal of endometrial polyps, submucous fibroids, uterine septum or intrauterine adhesions, which are present in 10% to 15% of women seeking treatment for subfertility.

OBJECTIVES

To assess the effects of the hysteroscopic removal of endometrial polyps, submucous fibroids, uterine septum or intrauterine adhesions suspected on ultrasound, hysterosalpingography, diagnostic hysteroscopy or any combination of these methods in women with otherwise unexplained subfertility or prior to intrauterine insemination (IUI), in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI).

SEARCH METHODS

We searched the following databases from their inception to 16 April 2018; The Cochrane Gynaecology and Fertility Group Specialised Register, the Cochrane Central Register of Studies Online, ; MEDLINE, Embase , CINAHL , and other electronic sources of trials including trial registers, sources of unpublished literature, and reference lists. We handsearched the American Society for Reproductive Medicine (ASRM) conference abstracts and proceedings (from 1 January 2014 to 12 May 2018) and we contacted experts in the field.

SELECTION CRITERIA

Randomised comparison between operative hysteroscopy versus control for unexplained subfertility associated with suspected major uterine cavity abnormalities.Randomised comparison between operative hysteroscopy versus control for suspected major uterine cavity abnormalities prior to medically assisted reproduction.Primary outcomes were live birth and hysteroscopy complications. Secondary outcomes were pregnancy and miscarriage.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion and risk of bias, and extracted data. We contacted study authors for additional information.

MAIN RESULTS

Two studies met the inclusion criteria.1. Randomised comparison between operative hysteroscopy versus control for unexplained subfertility associated with suspected major uterine cavity abnormalities.In women with otherwise unexplained subfertility and submucous fibroids, we were uncertain whether hysteroscopic myomectomy improved the clinical pregnancy rate compared to expectant management (odds ratio (OR) 2.44, 95% confidence interval (CI) 0.97 to 6.17; P = 0.06, 94 women; very low-quality evidence). We are uncertain whether hysteroscopic myomectomy improves the miscarriage rate compared to expectant management (OR 1.54, 95% CI 0.47 to 5.00; P = 0.47, 94 women; very low-quality evidence). We found no data on live birth or hysteroscopy complication rates. We found no studies in women with endometrial polyps, intrauterine adhesions or uterine septum for this randomised comparison.2. Randomised comparison between operative hysteroscopy versus control for suspected major uterine cavity abnormalities prior to medically assisted reproduction.The hysteroscopic removal of polyps prior to IUI may have improved the clinical pregnancy rate compared to diagnostic hysteroscopy only: if 28% of women achieved a clinical pregnancy without polyp removal, the evidence suggested that 63% of women (95% CI 45% to 89%) achieved a clinical pregnancy after the hysteroscopic removal of the endometrial polyps (OR 4.41, 95% CI 2.45 to 7.96; P < 0.00001, 204 women; low-quality evidence). We found no data on live birth, hysteroscopy complication or miscarriage rates in women with endometrial polyps prior to IUI. We found no studies in women with submucous fibroids, intrauterine adhesions or uterine septum prior to IUI or in women with all types of suspected uterine cavity abnormalities prior to IVF/ICSI.

AUTHORS' CONCLUSIONS

Uncertainty remains concerning an important benefit with the hysteroscopic removal of submucous fibroids for improving the clinical pregnancy rates in women with otherwise unexplained subfertility. The available low-quality evidence suggests that the hysteroscopic removal of endometrial polyps suspected on ultrasound in women prior to IUI may improve the clinical pregnancy rate compared to simple diagnostic hysteroscopy. More research is needed to measure the effectiveness of the hysteroscopic treatment of suspected major uterine cavity abnormalities in women with unexplained subfertility or prior to IUI, IVF or ICSI.

The randomised uterine septum transsection trial (TRUST): design and protocol

BACKGROUND

A septate uterus is a uterine anomaly that may affect reproductive outcome, and is associated with an increased risk for miscarriage, subfertility and preterm birth. Resection of the septum is subject of debate. There is no convincing evidence concerning its effectiveness and safety. This study aims to assess whether hysteroscopic septum resection improves reproductive outcome in women with a septate uterus.

METHODS/DESIGN

A multi-centre randomised controlled trial comparing hysteroscopic septum resection and expectant management in women with recurrent miscarriage or subfertility and diagnosed with a septate uterus. The primary outcome is live birth, defined as the birth of a living foetus beyond 24 weeks of gestational age. Secondary outcomes are ongoing pregnancy, clinical pregnancy, miscarriage and complications following hysteroscopic septum resection. The analysis will be performed according to the intention to treat principle. Kaplan-Meier curves will be constructed, estimating the cumulative probability of conception leading to live birth rate over time. Based on retrospective studies, we anticipate an improvement of the live birth rate from 35% without surgery to 70% with surgery. To demonstrate this difference, 68 women need to be randomised.

DISCUSSION

Hysteroscopic septum resection is worldwide considered as a standard procedure in women with a septate uterus. Solid evidence for this recommendation is lacking and data from randomised trials is urgently needed.

TRIAL REGISTRATION

Dutch trial registry ( NTR1676 , 18th of February 2009).

Three-dimensional scan of the uterine cavity of infertile women before assisted reproductive technology use

The primary objective was to assess the utility of routine 3-dimensional (3D) ultrasound in the evaluation of infertile women and to estimate the prevalence of uterine anomalies before the use of assisted reproductive technology (ART), using the European Society of Human Reproduction and Embryology and the European Society for Gynaecological Endoscopy classification system. A second objective was to assess the effect of uterine anomalies on the pregnancy rate in patients who underwent assisted reproductive techniques.We retrospectively studied 668 patients treated in the Department Obstetrics Gynecology and Neonatology "Sf Ioan" Clinical Emergency Hospital and in the Department of Medical and Surgical Specialties, Faculty of Medicine "'Transilvania" University of Brasov between July 2016 and February 2017 for subfertility. Patients were examined using 2-dimensional (2D) and 3-dimensional (3D) transvaginal ultrasound. Müllerian duct anomalies were present in 6.13% of patients, with the most common anomaly being a dysmorphic uterus (class U1c in 42.68% of patients), 17 patients (20.73%) with incompletely septate uterus (class U2a), 12 patients (14.63%) with a completely septate uterus (classU2b), 8 patients (9.75%) with a partly bicorporeal uterus (classU3a), and 6 patients (7.31%) with a completely bicorporeal uterus (class U3b). Only 1 (1.21%) patient had an aplastic uterus without a rudimentary cavity (class U5b). The pregnancy rate in the presence of uterine anomalies was 55% and the pregnancy rate in control group patients was 39.8%. The incidence of pregnancy in the group with uterine anomalies was statistically similar with the control group of normal uterus (P < .11). For ongoing pregnancy rate and live birth rate, our data indicated a slightly elevated rate for both of those indexes in the anomalies group. The incidence of miscarriage in the presence of uterine anomalies was 24% and 6.7% in the control group, which is statistically significant (P = .05).3D ultrasound evaluation of the uterus should be considered before ART in order to make an accurate diagnosis of the uterine congenital anomaly and improve ART results.

The Diagnosis and Surgical Approach of Uterine Septa

Uterine septa are a class of müllerian duct anomaly that, similar to other classes, are associated with poor reproductive outcomes; however, they are unique because these poor outcomes, particularly recurrent pregnancy loss, may be responsive to surgical correction. The current evidence regarding septoplasty is difficult to interpret because the definitions of a uterine septum, methods to diagnose it, and hysteroscopic techniques used for treatment are variable and generally of poor to moderate quality. Robust data on outcomes, particularly live births, after septoplasty are not available at this time. This review aims to examine the evidence on this contentious issue. A search of the literature was conducted using the MEDLINE, Embase, and Cochrane databases from 2002 to present with included articles reporting on clinical and/or imaging diagnosis of a uterine septum, operative techniques for uterine septoplasty, or clinical outcomes for women with uterine septa. The initial search revealed 4997 potentially relevant articles with 36 full-text articles included after the removal of nonrelevant titles, including 16 diagnostic studies, 17 surgical studies, and 3 studies on clinical outcomes. Where access to 3-dimensional transvaginal ultrasound or magnetic resonance imaging exists, these imaging modalities offer a highly sensitive and specific method of diagnosing a uterine septum without invasive diagnosis although this is operator dependent. Despite hysteroscopic septoplasty being described for over 40 years, there remains a lack of high-quality data to support hysteroscopic septoplasty and which women would most benefit from the procedure. There is no evidence for pre- or postoperative treatments nor has a single surgical approach been identified as superior than another although an important end point of live birth rates is largely unreported in these trials. Although several classification systems have been described, the diagnostic categorization of septal variants has limited a meaningful approach to this issue in both the clinical and research setting.
