Metroplasty for AFS Class V and VI Septate Uterus in Patients With Infertility or Miscarriage: Reproductive Outcomes Study

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.

[First-line management of infertile couple. Guidelines for clinical practice of the French College of Obstetricians and Gynecologists 2022]

OBJECTIVE

To update the 2010 CNGOF clinical practice guidelines for the first-line management of infertile couples.

MATERIALS AND METHODS

Five major themes (first-line assessment of the infertile woman, first-line assessment of the infertile man, prevention of exposure to environmental factors, initial management using ovulation induction regimens, first-line reproductive surgery) were identified, enabling 28 questions to be formulated using the Patients, Intervention, Comparison, Outcome (PICO) format. Each question was addressed by a working group that had carried out a systematic review of the literature since 2010, and followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) methodology to assess the quality of the scientific data on which the recommendations were based. These recommendations were then validated during a national review by 40 national experts.

RESULTS

The fertility work-up is recommended to be prescribed according to the woman's age: after one year of infertility before the age of 35 and after 6months after the age of 35. A couple's initial infertility work-up includes a single 3D ultrasound scan with antral follicle count, assessment of tubal permeability by hysterography or HyFOSy, anti-Mullerian hormone assay prior to assisted reproduction, and vaginal swabbing for vaginosis. If the 3D ultrasound is normal, hysterosonography and diagnostic hysteroscopy are not recommended as first-line procedures. Chlamydia trachomatis serology does not have the necessary performance to predict tubal patency. Post-coital testing is no longer recommended. In men, spermogram, spermocytogram and spermoculture are recommended as first-line tests. If the spermogram is normal, it is not recommended to check the spermogram. If the spermogram is abnormal, an examination by an andrologist, an ultrasound scan of the testicles and hormonal test are recommended. Based on the data in the literature, we are unable to recommend a BMI threshold for women that would contraindicate medical management of infertility. A well-balanced Mediterranean-style diet, physical activity and the cessation of smoking and cannabis are recommended for infertile couples. For fertility concern, it is recommended to limit alcohol consumption to less than 5 glasses a week. If the infertility work-up reveals no abnormalities, ovulation induction is not recommended for normo-ovulatory women. If intrauterine insemination is indicated based on an abnormal infertility work-up, gonadotropin stimulation and ovulation monitoring are recommended to avoid multiple pregnancies. If the infertility work-up reveals no abnormality, laparoscopy is probably recommended before the age of 30 to increase natural pregnancy rates. In the case of hydrosalpinx, surgical management is recommended prior to ART, with either salpingotomy or salpingectomy depending on the tubal score. It is recommended to operate on polyps>10mm, myomas 0, 1, 2 and synechiae prior to ART. The data in the literature do not allow us to systematically recommend asymptomatic uterine septa and isthmoceles as first-line surgery.

CONCLUSION

Based on strong agreement between experts, we have been able to formulate updated recommendations in 28 areas concerning the initial management of infertile couples.

Fertility-enhancing hysteroscopic surgery; multi-center retrospective cohort study of reproductive outcome

INTRODUCTION

Hysteroscopic surgery and assisted reproduction technology are feasible ways to improve the reproductive outcome. Our aim was to study hysteroscopic septoplasty and myomectomy's effect on infertility and reproductive performance.

METHODS

Retrospective cohort of patients who had unexplained infertility and/or recurrent miscarriages and had myomectomy or septoplasty in the period September 2016-october 2021 with a total of 18 months' follow up. The main outcome measures were spontaneous pregnancy, term pregnancy and miscarriage. For analysis, we used Statistical Package for Social Sciences (SPSS) version 20.

RESULTS

One hundred and sixty-five patients were included. The mean age of patients was 39 years. 40 patients had septum resection and 125 patients had hysteroscopic myomectomy. A spontaneous pregnancy rate after surgery was achieved in 46 patients (27.9%). Out of the 64 patients who had failed IVF preoperatively, 32 patients (50%) had a successful IVF post-hysteroscopic surgery and there were more successful cases in the patients who had fibroid resection but this difference did not reach a statistical significance (P value 0.055). In the 79 pregnancies after surgery, preterm birth and miscarriage were seen in 10 patients (12.7%), similarly, respectively after septal or fibroid resection. Miscarriages were less post-operatively. Hysteroscopic myomectomy, compared with hysteroscopic metroplasty, was significantly associated with higher spontaneous pregnancy rate (63.0% Vs 37.0%, P value 0.018), more term pregnancies (87.5% vs. 12.5%, P value 0.001) and less miscarriage rate (40%vs 60%, P value 0.003). Pregnancy post-operatively in patients with primary infertility was more statistically significantly associated with hysteroscopic myomectomy than with hysteroscopic septoplasty (95.8% vs. 4.2%, p value 0.030). In patients who got pregnant postoperatively there was no statistically significant difference in the mode of delivery.

CONCLUSION

In carefully selected patients with unexplained infertility and recurrent miscarriage, hysteroscopic myomectomy, compared with hysteroscopic metroplasty, was significantly associated with higher spontaneous pregnancy, more term pregnancies and less miscarriage rates. More than metroplasty, hysteroscopic myomectomy led to higher spontaneous pregnancies in patients with primary infertility.

Reproductive outcomes of natural pregnancy after hysteroscopic septum resection in patients with a septate uterus: a systematic review and meta-analysis

OBJECTIVE

The aim of this systematic review and meta-analysis was to analyze the reproductive outcomes of natural pregnancy after hysteroscopic septum resection in patients with recurrent miscarriage, primary infertility, or secondary infertility.

DATA SOURCES

The PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, VIP Database, and Chinese Biomedical Literature Database (CBM) databases were electronically searched. The search time frame was from inception up to July 2021. The English search terms were (arcuate* and uter*), (sept* and uter*), (subseptate* and uter*), metroplast*, septoplast*, and resect*.

STUDY ELIGIBILITY CRITERIA

Selection criteria included randomized controlled trials, cohort studies, and case series that explored reproductive outcomes after hysteroscopic septum resection in patients with recurrent miscarriage, primary infertility, or secondary infertility with or without a control group.

METHODS

The primary outcomes were the live birth rate and eventual postoperative live birth rate after hysteroscopic septum resection. The secondary outcomes were the clinical pregnancy rate, preterm birth rate, and miscarriage rate. Study-level proportions of outcomes were transformed using the Freeman-Tukey double-arcsine transformation to calculate pooled values for the postoperative rates; the counted data were analyzed using relative risk as the effect analysis statistic, and each effect size was provided with its 95% confidence interval. Heterogeneity between the results of the included studies was analyzed using the I² test.

RESULTS

Overall, 5 cohort studies and 22 case series involving 1506 patients were included. In patients with a septate uterus and recurrent miscarriage, hysteroscopic septum resection was associated with an increased live birth rate (relative risk, 1.77; 95% confidence interval, 1.26-2.49; P=.001; I²=0%), resulting in a postoperative live birth rate of 66% (95% confidence interval, 59-72), and septum resection was associated with a reduced preterm birth rate (relative risk, 0.15; 95% confidence interval, 0.04-0.53; P=.003; I²=0%) and miscarriage rate (relative risk, 0.36; 95% confidence interval, 0.20-0.66; P=.0009; I²=0%). In patients with a septate uterus and primary infertility, hysteroscopic septum resection was associated with an increased live birth rate (relative risk, 4.12; 95% confidence interval, 1.19-14.29; P=.03; I²=0%) and clinical pregnancy rate (relative risk, 2.28; 95% confidence interval, 1.04-4.98; P=.04; I²=0%). The postoperative live birth rate was 37% (95% confidence interval, 30-44), and the miscarriage rate of patients with primary infertility was reduced (relative risk, 0.19; 95% confidence interval, 0.06-0.56; P=.003). The efficacy of hysteroscopic septum resection in patients with secondary infertility was unclear. However, their postoperative live birth rate was found to be 41% (95% confidence interval, 2-88).

CONCLUSION

Hysteroscopic septum resection is associated with an increased live birth rate and a reduced miscarriage rate in patients with recurrent miscarriage or primary infertility, indicating that septum resection may improve the reproductive outcomes of these patients. The effectiveness of septum resection was unclear for patients with secondary infertility. These findings are limited by the quality of the included studies, warranting further randomized controlled trials, including only patients with recurrent miscarriage or primary infertility.

Does uterine septum resection improve IVF treatment success?

Aim: Uterine septum is the most common type of congenital uterine malformation. The septum has also been suggested as a potential cause of infertility. The role of the septum in infertility and whether the septum can be resected is debatable. We aimed to reveal the results of assisted reproductive techniques in patients with septate uterus according to whether or not resection is performed. Material and Method: 7790 patients were scanned retrospectively. 110 patients with the uterine septum and unexplained infertility were included in the study. Patients who underwent uterine septum resection were recorded. The clinical pregnancies of patients were compared according to whether or not resection was performed. In addition, patients with complete septum were evaluated according to whether or not resection was performed, and their clinical pregnancies were evaluated. Results: It was revealed that 79 of the patients with uterine septum underwent septum resection operation. It was determined that 31 patients were not treated. Clinical pregnancy rates were found to be statistically significantly higher in the expectant management group (p=0.02). In addition, comparing the clinical pregnancy rates of the resection and expectant management groups in patients with a complete septum, no significant difference was found between the groups (p=0.134). Conclusion: In our study, the success of treatment with assisted reproductive techniques did not change after septum resection. Although uterine septum resection is a simple and safe method, it has disadvantages such as the development of adhesions and rupture in the uterus. There is insufficient evidence to perform septum resection in patients with uterine septum prior to infertility treatment.

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.

Effect of hyteroscopic uterine septum resection on pregnancy outcomes

OBJECTIVE

To compare the reproductive outcome following hysteroscopic resection versus usual care in nulliparous women with a septate uterus.

METHODS

A retrospective cohort study of nulliparous women with a history of uterine septum and had singleton pregnancies at >20 weeks gestation between Jan. 2016 and Dec. 2019 were conducted. Follow-up was performed through medical record reviews and telephone conversations. The primary outcome was preterm birth at<37weeks gestation, and the secondary outcomes include cesarean delivery, malpresentation, preeclampsia, and birth weight<10th percentile for gestational age. Multivariate logistic regressions were performed to evaluate the effect of hysteroscopic resection on primary and secondary outcomes, after controlling for potential confounding factors.

RESULTS

Totally 198 women were included in this study, among which 112 women underwent a hysteroscopic resection and 86 women received usual care. Preterm birth incidence (7.1% vs. 18.6%, P = 0.03) and malpresentation (10.7% vs. 23.3%, P = 0.03) was significantly lower in women treated with hysteroscopic resection compared with those received usual care. Multivariate logistic regression indicated that hysteroscopic resection was significantly associated with decreased risks of preterm birth (OR = 0.36, 95% CI: 0.13-0.68; P < 0.01) and malpresentations (OR = 0.47, 95% CI: 0.25-0.71; P < 0.01), after controlling for potential confounding factors.

CONCLUSION

Hysteroscopic resection could significantly reduce the risks of preterm birth and malpresentations compared to usual care for nulliparous women with a septate uterus.

Uterine Fundus Remodeling after Hysteroscopic Metroplasty: A Prospective Pilot Study

The septate uterus is the most common congenital uterine malformation and is treated by hysteroscopic metroplasty. There are few studies on the fundal uterine changes that occur after surgery. We designed a pilot prospective observational study to evaluate by three-dimensional transvaginal ultrasound (3D-TVS) the changes not only of the internal fundal uterine profile, but also of the external one, after hysteroscopic metroplasty. Sixty women who underwent hysteroscopic metroplasty for partial or complete uterine septum (U2a and U2b subclasses of ESHRE/ESGE classification) were enrolled. We performed 3D-TVS after surgery confirming optimal removal of the septum. However, at ultrasound follow-up after three months, we observed a significant increase (p < 0.001) in the residual septum (Zr) (3.7 mm (95% CI: 3.1-4.4)), the myometrial wall thickness (Y) (2.5 mm (95% CI: 2.0-3.0)) and the total fundal wall thickness (Y + Zr) (6.2 mm (95% CI: 5.5-6.9)). Forty-three patients (72%) required a second step of hysteroscopic metroplasty. Moreover, the shape of uterine fundus changed in 58% of cases. We actually observed a remodeling of the uterine fundus with modifications of its external and internal profiles. Therefore, we propose to always perform a second ultrasound look at least three months after the metroplasty to identify cases that require a second- step metroplasty.

Reproductive Outcomes of Hysteroscopic Septoplasty Techniques

Background and Objectives:

Since little is known regarding the correlation between different techniques used during hysteroscopic septoplasty and reproductives outcomes, we amied to evaluate the results of two different techniques of hysteroscopic septoplasty (HS).

Methods:

Data were retrospectively reviewed on 49 patients who underwent HS for symptomatic septate uterus from January 1, 2010, through April 30, 2014. The patients were divided into 2 groups based on the HS technique used. Group I consisted of 27 patients who underwent HS by monopolar hook cautery with the operating hysteroscope. Group II consisted of 22 patients who had the procedure performed with scissors and guided by an office hysteroscope. All the procedures in the both groups were performed in the operating room under general anesthesia. Pregnancy outcomes within the first year after HS for both groups were evaluated.

Results:

Reproductive outcomes were obtained from 44 patients who attempted to conceive after HS within the first year. In the 25 patients in group I, 23 had pregnancies, of which 15 (65.2%) continued to term, 3 (13%) ended in a preterm live birth, and 5 (21.7%) ended in loss of pregnancy (abortion). In the 19 patients in group II, there were 17 pregnancies, of which 11 (64.7%) continued to term, 2 (11.7%) ended in a preterm live birth, and 4 (23.5%) ended in first- or second-trimester abortion. The overall live-birth rate was 78.2% in group I and 76.4% in group II (P = .85).

Conclusions:

Our data show that the rates of pregnancy that reach term and overall rates of live births are similar between the 2 HS techniques. Additional studies are needed to evaluate the impact of the techniques on reproductive outcomes.

The techniques and outcomes of hysteroscopic metroplasty

PURPOSE OF REVIEW

To evaluate the reproductive outcomes and surgical techniques of the hysteroscopic metroplasty in women with septate uterus and recurrent abortions or primary unexplained infertility.

RECENT FINDINGS

Septate uterus is the most frequent congenital uterine anomaly caused by inadequate resorption of the Müllerian ducts. Hysteroscopic metroplasty has replaced the traditional laparotomy approach because of its positive and satisfactory outcomes in pregnancy and live-birth rates, and also many different postoperative benefits. The aim of metroplasty is to restore a normal anatomy of the uterine cavity as a prerequisite for a positive implantation and subsequent good obstetrical outcomes. This treatment clearly demonstrates its effectiveness both in recurrent abortion and in primary unexplained infertility.

SUMMARY

The hysteroscopic metroplasty with its simplicity, safety, and improved reproductive outcomes has liberalized the approach to treatment. Today, hysteroscopic metroplasty is a common practice to treat septate uterus with salutary effects both in infertile patients and in patients with recurrent pregnancy loss or premature labor, especially if in-vitro fertilization is being contemplated. Decisions on when to treat uterine septa are discussed in particular because of lack of prospective, randomized controlled trials.

Do measurements of uterine septum using three-dimensional ultrasound and magnetic resonance imaging agree?

OBJECTIVE

To evaluate the agreement between measurements of uterine septum by 3-D ultrasound (3-D US) and magnetic resonance imaging.

METHODS

Fourteen women with a uterine septum underwent both a 3-D US and an MRI followed by hysteroscopic metroplasty in a tertiary care infertility clinic within a university teaching hospital. The agreement between 3-D US and MRI measurements of septum length (SL), septum width (SW) and the distance between fundal serosa and septal tip (SSD) was compared using the Bland Altman limit of agreement analysis.

RESULTS

3-D US correctly identified all women who had a uterine septum identified with MRI. The mean difference in SL was 2.7 mm (upper limit of agreement and lower limit of agreement were 10.3 mm and -4.8 mm, respectively). The mean difference in SW was 2.3 mm (upper limit of agreement and lower limit of agreement of 10.4 mm and -9.2 mm, respectively). The SSD mean difference was 2.8 mm (upper limit of agreement and lower limit of agreement of 10.6 mm and -5 mm, respectively).

CONCLUSIONS

Categorical agreement in diagnosis was 100% and agreement between 3-D US and MRI measurements was good with narrow differences. Variations were unlikely to be greater than intra- and inter-observer variations anticipated in MRI readings. 3-D US can replace MRI for diagnosis and measurement of uterine septa.
