Small-diameter hysteroscopy with Versapoint versus resectoscopy with a unipolar knife for the treatment of septate uterus: A prospective randomized study

Reproductive outcomes after TCRS in patients with incomplete and complete uterine septum: a retrospective cohort study

Objective

This study aimed to evaluate the effects of transcervical resection of the septum (TCRS) on reproductive outcomes in women of reproductive age with two types of uterine septa.

Methods

In this retrospective cohort study, we evaluated the reproductive outcomes after TCRS in 87 women with an incomplete uterine septum and 35 women with a complete uterine septum. The study was conducted from January 2010 to December 2020 at the Second Affiliated Hospital of Anhui Medical University in China.

Results

In Group A (incomplete uterine septum), TCRS markedly decreased the rates of spontaneous abortion and embryonic arrest (p < 0.001) while significantly enhancing the likelihood of term delivery (p < 0.001). Similarly, Group B (complete uterine septum) observed a substantial increase in pregnancy rates (from 43.5 to 82.6%), a significant decrease in spontaneous abortions (p < 0.05), and an improvement in term delivery rates (p < 0.001) post-surgery. The dimension of the septum in cases of Group A did not affect the outcome of adverse reproductive events. However, cesarean section rates were significantly higher in Group B than in Group A (76.5% vs. 47.7%). The optimal time to achieve pregnancy was within the first year for Group A and the 12th month for Group B after TCRS.

Conclusion

In patients undergoing TCRS, a notable decrease in spontaneous abortion rates was observed, alongside an increase in pregnancy and full-term birth rates. However, there was a concomitant rise in cesarean section rates. Furthermore, our findings indicate that patients with an incomplete uterine septum are more likely to conceive earlier than those with a complete uterine septum following surgery, thereby optimizing the timing for pregnancy.

Intraoperative ultrasound for uterine septum resection: a systematic review and meta-analysis

Septate uterus is one of the most common uterine malformations. Recent studies suggest that uterine septa may negatively affect fertility. In cases of recurrent pregnancy loss (RPL) or infertility, hysteroscopic metroplasty has been considered the primary treatment for septate uterus. This systematic review and meta-analysis aims to evaluate whether intraoperative ultrasound monitoring may improve the efficacy of hysteroscopic metroplasty compared to other types of intraoperative monitoring or to unguided resections. An electronic database search was performed to identify articles published until June 15, 2023. Five studies (two randomized clinical trials, two prospective studies and one retrospective cohort study) fulfilled the inclusion criteria. The primary outcome was the rate of residual septum > 10 mm after hysteroscopic metroplasty in the ultrasound (US) monitoring group compared to the rate of residual septum using other types of intraoperative monitoring/no monitoring (control group). The secondary outcomes were any residual septa, surgical time, complications, uterine perforations and reproductive outcomes. Intraoperative ultrasound for uterine septum resection significantly reduced the rate of residual septum > 10 mm and the rate of any residual septa compared to the control group. There was no statistically significant difference in the procedure time between women undergoing intraoperative US monitoring versus the control group. A trend toward reduction of surgical complications was observed in the intraoperative US group compared to the control group. In conclusion, intraoperative ultrasound during metroplasty may reduce the rate of the residual septum with no surgical time differences. Further studies are warranted to understand how this may improve reproductive outcomes.

Incidence and risks of excessive distension absorption in hysteroscopic surgery using 5% mannitol solution: a retrospective descriptive study

OBJECTIVE

To clarify the incidence of excessive distension absorption in hysteroscopic surgery using 5% mannitol solution, evaluate the associated risks, and help to establish a safe fluid deficit threshold for such complication.

DESIGN

Retrospective descriptive study.

SETTING

Academic medical center.

PATIENTS

Ten thousand six hundred ninety-three patients underwent inpatient hysteroscopic surgery with 5% mannitol perfusion using a monopolar electrosurgical instrument from Jan. 2015 to Sep. 2020.

INTERVENTION(S)

None. This study has been approved by the Ethics Committee of Sun Yat-sen Memorial Hospital.

MEASUREMENTS AND MAIN RESULTS

A fluid deficit of more than 1000 mL was defined as the diagnostic criteria for excessive distension absorption. The overall incidence of excessive distension absorption in this study was 0.46% (49/10693). The incidence was 2.57% (16/623) for transcervical resection of fibroid (TCRF), 2.36% (9/381) for retained products of conception (RPOC) removal, 1.20% (6/501) for hysteroscopic uterine septum resection (HSR), 0.48% (4/828) for transcervical resection of the endometrium (TCRE), and 0.53% (14/2621) for transcervical resections of adhesion (TCRA). Excessive distension absorption could occur within seven minutes in HSR. Among the patients diagnosed with excessive distension absorption, 30.77% (12/39) exhibited signs or symptoms related to circulation overload with a fluid deficit under 2500 mL, and 10.26% (4/39) developed pulmonary edema.

CONCLUSION

Excessive distension absorption could happen in all kinds hysteroscopic surgical treatment including RPOC removal and TCRA which were rarely reported. The overall incidence of excessive distension absorption could be low. But it would be five times higher in certain procedures such as TCRF, RPOC removal and TCRA. Resection using a needle electrode in HSR and TCRA may contribute to the short time development of excessive distension absorption. 30.77% of the patients could not tolerate the fluid deficit of less than 2500 mL which was set as a threshold for isotonic distending media and presented with circulation overload related signs or symptoms.

Predictors of Infused Distending Fluid Volume in Hysteroscopic Myomectomy

Background and Objectives: The use of a bipolar resectoscope has become popular due to the lower risk of hyponatremia. However, gynecologists might overlook the risk of water intoxication. Water intoxication is associated with the infusion of distending fluid. We were interested in the prediction of the infused distending fluid volume in the era of bipolar hysteroscopy. Thus, the aim of this study was to identify the predictors of the infused distending fluid volume for hysteroscopic myomectomy. Materials and Methods: All consecutive women who underwent monopolar (n = 45) or bipolar (n = 137) hysteroscopic myomectomy were reviewed. Results: Myoma diameter (cm, coefficient = 680 mL, 95% confidence interval (CI) = 334-1025 mL, p <0.001) and bipolar hysteroscopy (coefficient = 1629 mL, 95% CI = 507-2752 mL, p = 0.005) were independent predictors of infused distending fluid volume. A myoma diameter ≥4.0 cm was the optimal cutoff value to predict the presence of >5000 mL of infused distending fluid. One woman in the bipolar group developed life-threatening water intoxication. Conclusions: Myoma diameter is associated with an increase in infused distending fluid volume, especially for myomas ≥4 cm. Meticulous monitoring of the infused distension fluid volume is still crucial to avoid fluid overload during bipolar hysteroscopic myomectomy.

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.

Intraoperative Three-Dimensional Transvaginal Ultrasound for Hysteroscopic Metroplasty: a Controlled Study

This study aims to evaluate the role of intraoperative transvaginal three-dimensional ultrasound (3DUS) during hysteroscopic metroplasty. This is a prospective cohort of consecutive patients with septate uterus undergoing hysteroscopic metroplasty with intraoperative transvaginal 3DUS guidance compared to a historical control group of patients undergoing hysteroscopic metroplasty without 3DUS. We conducted our research in a tertiary care university hospital in Rome, Italy. This study involved nineteen patients undergoing 3DUS-guided hysteroscopic metroplasty for recurrent abortion or infertility compared to 19 age-matched controls undergoing metroplasty without 3DUS guidance. During hysteroscopic metroplasty, 3DUS was performed in the study group when the operator considered the procedure to be completed, according to standards of operative hysteroscopy. If 3DUS diagnosed a residual septum, the procedure was continued until a 3DUS diagnosis of a normal fundus was obtained. The patients were followed with a 3DUS performed 3 months after the procedure. The numbers of complete resections (residual septum absent), suboptimal resections (measurable residual septum of less than 10 mm), and incomplete resections (residual septum > 10 mm) in the intraoperative 3DUS group were compared to the numbers in the control group with no intraoperative 3DUS. At follow-up, measurable residual septa were obtained in 0% of the patients in the 3DUS-guided group versus 26% in the control group (p = 0.04). Residual septa of > 10 mm were obtained in 0% of the 3DUS group versus 10.5% in the control group (p = 0.48). Intraoperative 3DUS reduces the incidence of suboptimal septal resections at hysteroscopic metroplasty.

Pregnancy and Adverse Obstetric Outcomes After Hysteroscopic Resection: A Systematic Review and Meta-Analysis

Objective

Although the randomized controlled trial (RCT) of the efficacy of hysteroscopic resection in women with uterine septum has not shown any significant correlation in recent research, motivation for deeper study remains insufficient. In this study, the objective was to determine pregnancy-related outcomes, along with adverse obstetric outcomes, following hysteroscopic resection and also to determine whether women with hysteroscopic resection bear the same outcomes as women with normal uterine cavities.

Search Methods

From January 1995 to February 2022, a systematic literature review was conducted to identify all studies published concerning the gestation outcomes of women with and without hysteroscopic resection while comparing the gestation outcomes of women after hysteroscopic resection and with a normal uterine cavity. Our primary outcome was the live birth rate (LBR). The secondary outcomes were term delivery, preterm delivery, spontaneous miscarriage, malpresentation, cesarean section, and other adverse obstetric outcomes.

Results

22 studies were included in this meta-analysis. The control groups of 14 studies were treated women, and the control groups of the other 8 studies were patients bearing a normal uterine cavity. Hysteroscopic resection was related to a higher rate of term delivery (OR = 2.26, 95% CI, 1.26–4.05), and a lower rate of spontaneous abortion (OR = 0.50, 95% CI, 0.27–0.93), and a lower rate of malpresentation (OR = 0.31, 95% CI, 0.19–0.50). Nevertheless, in comparison with the normal uterus group, the rates of preterm birth, cesarean section, and postpartum hemorrhage after resection did not return to normal levels.

Conclusion

Hysteroscopic resection can effectively reduce the risk of abortion and malpresentation in patients possessing a uterine septum while increasing the term delivery rate. Although well-designed RCTs should confirm our meta-analysis, it still bears recommending to patients

A Prospective Randomized Comparative Clinical trial of Hysteroscopic Septal Resection Using Conventional Resectoscope Versus Mini-resectoscope

CONTEXT

Hysteroscopic metroplasty (HM) is the gold standard treatment for women with septate uterus with recurrent pregnancy loss. Miniresectoscope requires less cervical dilatation as compared to conventional resectoscope. Very few studies are available in the literature on use of miniresectoscope for operative purpose.

AIM OF THE STUDY

This study aimed to compare operative and postoperative outcome parameters using conventional versus mini resectoscope (MR) for hysteroscopic septal resection (HSR).

STUDY SETTINGS AND DESIGN

This was a prospective randomized controlled trial conducted in the Department of Obstetrics and Gynaecology from July 2017 to May 2019.

MATERIALS AND METHODS

Forty patients fulfilling the inclusion criteria were recruited and randomized into two groups. In Group A (20 patients), HSR was done using conventional resectoscope (CR) and in Group B (20 patients), MR was used. The various parameters recorded were cervical dilatation time, operating time, intraoperative complications, postoperative pain, and hospital stay and reproductive outcome post surgery in both groups.

RESULTS

Data analysis was carried out using SPSS IBM software version 20.0. The mean operating time was comparable but cervical dilatation time was significantly more in Group A. The duration of hospital stay was significantly less in Group B. There were no differences in adequacy of vision in both the groups but area of field was less in MR group. Four out of nine patients with infertility conceived after surgery. 65% in Group A and 70% in Group B conceived during follow up.

CONCLUSION

Our study showed that hysteroscopic metroplasty with MR, has comparable efficacy to CR in terms of good vision and septal resectability with added advantages of shorter cervical dilatation time, ease of entry of resectoscope, shorter operative time and significantly reduced postoperative morbidity in terms of less pain. However, the field of vision is less and resection time is more, hence more expertise is required. Further larger randomized trials are required.

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).

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 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.

A Prospective Randomized Study Comparing Unipolar Versus Bipolar Hysteroscopic Myomectomy in Infertile Women

Study Objective:

To compare the operative and reproductive outcome of hysteroscopic myomectomy using unipolar resectoscope versus bipolar resectoscope in patients with infertility and menorrhagia.

Design:

Randomized, prospective, parallel, comparative, single-blinded study.

Design Classification:

Canadian Task Force classification I.

Setting:

Tertiary care institute.

Patients:

Sixty women with submucous myoma and infertility.

Interventions:

Hysteroscopic myomectomy performed with unipolar resectoscope or bipolar resectoscope.

Measurements:

Primary outcome measures were the pregnancy-related indicators. Secondary outcome measures were the operative parameters, harmful outcomes related to the procedure, and comparison of improvement levels in the menstrual pattern after surgery between the two groups.

Main Results:

A total of 60 patients were randomized into two groups of equal size. Baseline characteristics were not significantly different between the two groups. Reduction in sodium level from pre- to postsurgery was significantly (P = 0.001) higher in the unipolar group. Nine patients (30%) in the unipolar group had hyponatremia in the postoperative period compared to none in the bipolar group (P = 0.002). However, there was no significant difference in the other operative parameters between the two groups. In both the groups, a significant improvement in the menstrual symptoms was observed after myomectomy. Pregnancy-related outcomes were similar in both the groups.

Conclusion:

The use of bipolar resectoscope for hysteroscopic myomectomy is associated with lesser risk of hyponatremia compared to unipolar resectoscope. Bipolar resectoscopic myomectomy is found to be an effective and safer alternative to unipolar resectoscopy with similar reproductive outcome.

Minimally Invasive Gynecologic Surgery for Benign Conditions: Progress and Challenges

OBJECTIVE

The objective of this review is to evaluate the progress made in laparoscopic and hysteroscopic gynecologic surgery and address challenges still faced by surgeons using minimally invasive techniques to improve the care of women with noncancerous gynecologic problems.

METHODS

Relevant literature was reviewed and evidence-based arguments put forward in the article for the progress that has been made and the deficiencies that still exist.

RESULTS

In the last 2 decades, enormous progress has been made in providing minimally invasive surgical options for women with gynecologic diseases. The progress has been especially striking in the performance of hysterectomy, the most common major surgery performed on nonpregnant women. The recent controversy over power morcellation has revealed a poor understanding of the literature concerning leiomyosarcoma leading to confusion and consequently denial of minimally invasive surgical options for many women. Hysteroscopic surgery has been evolving rapidly with the development of hysteroscopic morcellator, global endometrial ablation systems, and hysteroscopic tubal sterilization.

CONCLUSIONS

Although huge advances have been made in minimally invasive gynecologic surgery, high-quality evidence from well-designed clinical trials is lacking for many of the new technologies. Accurate estimates regarding the risk of occult leiomyosarcoma are also lacking. Additional research is urgently needed to address these deficiencies.

Comparative Study between Monopolar Electrodes and Bipolar Electrodes in Hysteroscopic Surgery

BACKGROUND

The hysteroscopic surgery has become a simple and safe technique, with the use of small hysteroscopes and bipolar energy with trained surgeons, which can prevent abortions and probably increase fertility.

AIM

The study was conducted to evaluate the outcomes after hysteroscopic surgery by using uninopolar or bipolar electrodes.

SETTING AND DESIGN

At the department of Obstetrics and Gynaecology, Qena university hospital and is a prospective non randomized clinical study.

MATERIALS AND METHODS

One hundred fifty patients who included in this study were non randomly classified into two groups; one for hysteroscopic surgery by using bipolar electrode and the second group using unipolar electrode. Operative complications; bleeding, perforation, fluid over load and hyponatraemia were recorded. Also, operative time and hospital stay were included.

RESULTS

There were no statistically significant differences between both groups in patient's characteristics, ultrasono-graphic findings, serum sodium levels before surgical interference, perforation and intraoperative bleeding. The fluid overload was significantly higher in unipolar group (p value= 0.03), postoperative hyponatraemia was significantly marked in unipolar group (p<0.05) and the changes of the levels of serum sodium in unipolar group in comparison to bipolar group were significantly different (p = 0.01). The mean operative time was significantly less in the bipolar group when compared to the unipolar group (p = 0.01) and the hospital stay was obviously less for patients of the bipolar group in comparison to unipolar group (p=0.04).

CONCLUSION

Operative hysteroscopy using bipolar electrodes associated with significant decrease in hyponatraemia, operative time and postoperative hospital stay. So, it is safe and effective method when compared to using the unipolar electrodes.

Does hysteroscopic metroplasty for septate uterus represent a risk factor for adverse outcome during pregnancy and labor?

The aim of the study was to evaluate whether hysteroscopic metroplasty for septate uterus represents a risk factor of adverse outcome in pregnancy, during labor, and after delivery. This is a retrospective comparative study of obstetric complications of 99 patients who underwent hysteroscopic metroplasty in a 5-year period (study group) and 4155 women, who gave birth in the same hospital in the same period (control group). No difference in obstetric outcome (preterm labor, hemorrhage before and after delivery, mean weeks of gestation at delivery, mean birth weight, breech presentation, and cesarean section rate) between the two groups has been found. The results of this study suggest that patients who underwent hysteroscopic metroplasty for septate uterus are at no higher risk of adverse obstetric outcome at term and during labor, comparing to the general population. Though vaginal delivery seems to be safe, rare but serious complication, reported by several studies, like uterine rupture during pregnancy or labor, should always be taken into consideration.

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 detectable 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 Cochrane Menstrual Disorders and Subfertility Specialised Register (8 September 2014), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2014, Issue 9), MEDLINE (1950 to 12 October 2014), EMBASE (inception to 12 October 2014), CINAHL (inception to 11 October 2014) 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 January 2013 to October 2014) and we contacted experts in the field.

SELECTION CRITERIA

Randomised comparisons between operative hysteroscopy versus control in women with otherwise unexplained subfertility or undergoing IUI, IVF or ICSI and suspected major uterine cavity abnormalities diagnosed by ultrasonography, saline infusion/gel instillation sonography, hysterosalpingography, diagnostic hysteroscopy or any combination of these methods. 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

We retrieved 12 randomised trials possibly addressing the research questions. Only two studies (309 women) met the inclusion criteria. Neither reported the primary outcomes of live birth or procedure related complications. In women with otherwise unexplained subfertility and submucous fibroids there was no conclusive evidence of a difference between the intervention group treated with hysteroscopic myomectomy and the control group having regular fertility-oriented intercourse during 12 months for the outcome of clinical pregnancy. A large clinical benefit with hysteroscopic myomectomy cannot be excluded: if 21% of women with fibroids achieve a clinical pregnancy having timed intercourse only, the evidence suggests that 39% of women (95% CI 21% to 58%) will achieve a successful outcome following the hysteroscopic removal of the fibroids (odds ratio (OR) 2.44, 95% confidence interval (CI) 0.97 to 6.17, P = 0.06, 94 women, very low quality evidence). There is no evidence of a difference between the comparison groups for the outcome of miscarriage (OR 0.58, 95% CI 0.12 to 2.85, P = 0.50, 30 clinical pregnancies in 94 women, very low quality evidence). The hysteroscopic removal of polyps prior to IUI can increase the chance of a clinical pregnancy compared to simple diagnostic hysteroscopy and polyp biopsy: if 28% of women achieve a clinical pregnancy with a simple diagnostic hysteroscopy, the evidence suggests that 63% of women (95% CI 50% to 76%) will achieve 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, moderate quality evidence).

AUTHORS' CONCLUSIONS

A large benefit with the hysteroscopic removal of submucous fibroids for improving the chance of clinical pregnancy in women with otherwise unexplained subfertility cannot be excluded. The hysteroscopic removal of endometrial polyps suspected on ultrasound in women prior to IUI may increase the clinical pregnancy rate. More randomised studies are needed to substantiate the effectiveness of the hysteroscopic removal of suspected endometrial polyps, submucous fibroids, uterine septum or intrauterine adhesions in women with unexplained subfertility or prior to IUI, IVF or ICSI.

Hysteroscopic septal resection using unipolar resectoscope versus bipolar resectoscope: Prospective, randomized study

AIM

To compare the operation and reproductive outcome of hysteroscopic septal resection using unipolar resectoscope verses bipolar resectoscope.

METHODS

In this prospective randomized study, 70 women underwent hysteroscopic septal resection using either unipolar resectoscope or bipolar resectoscope. Intraoperative parameters (operation time, fluid deficit and complications) and pre- and postoperative serum sodium levels were compared between the two groups. A second-look hysteroscopy was performed after 6 weeks. All pregnancies occurring during the follow-up period were recorded.

RESULTS

There was no statistically significant difference between the two groups in terms of operation parameters and second-look hysteroscopy findings. Six patients in the unipolar group were found to have hyponatremia in the postoperative period compared to none in the bipolar group (P = 0.025). Regarding reproductive outcome, the difference between the two groups was not significant.

CONCLUSION

The use of bipolar resectoscope is associated with lesser risk of hyponatremia compared to unipolar resectoscope. Bipolar resectoscopy is a safe alternative to unipolar resectoscopy with similar reproductive outcome.

Reproductive outcome following hysteroscopic treatment of uterine septum

BACKGROUND

Septate uterus is the most common uterine anomaly and a cause for miscarriage and infertility. Existing data suggested a better reproductive outcome of uterine septum following hysteroscopic septum resection.

OBJECTIVE

Current study was administered to share our experience in hystroscopic septum resection for reproductive outcome following hysteroscopic treatment of uterine septum and specifically focusing on different treatment protocols after hysteroscopic septum resection.

METHODS& MATERIALS

This study was a cross-sectional study based on secondary data that was obtained from medical records of infertile women who had undergone transvaginal hysteroscopy and used different treatment protocols after hysteroscopic correction of uterine septum in Infertility and Reproductive Health Research Center between April 2005 and February 2014.

RESULTS

The total number of infertile women underwent hysteroscopy uterine septoplasty was 106. The hysteroscopy septoplasty resulted in an overall pregnancy rate of 67% and a live birth 57.5%. Pregnancy rate for patients who had not male infertility was 92.1%. The chi-square test did not reveal any statistically significant difference in side affect, pregnancy, live birth, abortion, preterm deliveries, and term deliveries rate between these patients either with consistent hormone therapy plus IUD insertion or with alternate hormone therapy plus IUD after hysteroscopic metroplasty.

CONCLUSION

The findings of the present study indicated hysteroscopic septum resection to remove a uterine septum in women with infertility is safe and may be an efficacious procedure. Treatment following hysteroscopic septum resection, either the consistent or the alternate protocol is both beneficial to improve pregnancy rate.

[Hysteroscopic septoplasty: after miscarriages?]

OBJECTIVE

To assess reproductive outcome of women affected by septate uterus after surgical correction.

PATIENTS AND METHODS

It is a retrospective study. The setting is a French university hospital. Surgery was performed on 66 patients between 2000 and 2010. Hysteroscopic metroplasty was performed in every group once the diagnosis was made. There were two groups: 35 patients affected by septate uterus had past history of miscarriages, preterm and term deliveries. Thirty-six patients had never been pregnant.

RESULTS

In the group of 35 patients with a previous obstetric history, the rate of miscarriages was 57.1% before surgery and 10% after surgery. There was a significant gain of live birth ratio of 55% among women being pregnant after surgery compared to women being pregnant before surgery. For patients with no pregnancy before surgery, obstetrical results are the following ones: miscarriages 25.9%, preterm deliveries 11% and term deliveries 59.3%.

DISCUSSION AND CONCLUSION

Hysteroscopic septoplasty is an easy technique with few complications in our study. Hysteroscopic septoplasty is strongly recommended after recurrent miscarriages or premature deliveries. We use to propose surgery to every patient affected by septate uterus, even if they have never been pregnant.

Which luteal phase support is better for each IVF stimulation protocol to achieve the highest pregnancy rate? A superiority randomized clinical trial

In vitro fertilization (IVF) cycles generate abnormalities in luteal-phase sex steroid concentrations and this represent an important limiting factor to achieve a good pregnancy rate. Although there are evidences about the usefulness of luteal phase support (LPS) after IVF cycles, no consensus exist about the best dose and way of progesterone (PG) administration, the advantages of estradiol (E2) supplementation and which IVF protocol could benefit from one more than other LPS scheme. Aim of the study was to assess the best LPS (low-dose PG, high-dose PG, high-dose PG and E2 supplementation) to achieve the highest clinical/ongoing pregnancy rate according to stimulation protocol, E2 at ovulation induction, endometrial thickness at pick-up and women's age. We conducted a randomized trial on 360 women undergoing IVF (180 treated by long-GnRH agonist, 90 by short-GnRH agonist and 90 by short-GnRH antagonist protocol) and stimulated by recombinant follicle-stimulating hormone alone. Our data demonstrated that high-dose PG is better than low-dose to increase both clinical and ongoing pregnancy rate. E2 supplementation are mandatory in case of short-GnRH antagonist protocol and strongly suggested in all protocols when E2max <5 nmol/l and endometrial thickness <10 mm. In long-GnRH agonist protocols, as well as in patients >35 years, the real advantages of E2 supplementation remain debatable and require further confirmation.

Hysteroscopic metroplasty for the septate uterus: review and meta-analysis

The introduction of hysteroscopy to diagnose and treat intrauterine conditions, specifically to divide the uterine septum, or metroplasty, has replaced the traditional laparotomy approach, and objective results demonstrate its salutary effects in women treated. Hysteroscopic metroplasty averts the implications of major invasive abdominal surgery, with good and satisfactory results in pregnancy and live-birth rates, despite the lack of prospective, randomized, controlled studies. A careful review of the published results supports this type of treatment when the uterine septum adversely affects normal reproductive function.

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 detectable 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 Cochrane Menstrual Disorders and Subfertility Specialised Register (6 August 2012), the Cochrane Central Register of Controlled Trials (T he Cochrane Library 2012, Issue 7), MEDLINE (1950 to October 2012), EMBASE (1974 to October 2012), CINAHL (from inception to October 2012) 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 January 2008 to October 2012) and we contacted experts in the field.

SELECTION CRITERIA

Randomised comparisons between operative hysteroscopy versus control in women with otherwise unexplained subfertility or undergoing IUI, IVF or ICSI and suspected major uterine cavity abnormalities diagnosed by ultrasonography, saline infusion/gel instillation sonography, hysterosalpingography, diagnostic hysteroscopy or any combination of these methods. Primary outcomes were live birth and hysteroscopy complications. Secondary outcomes were pregnancy and miscarriage.

DATA COLLECTION AND ANALYSIS

Two 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 and neither reported the primary outcomes of live birth and complications from the procedure. In women with otherwise unexplained subfertility and submucous fibroids, there is no evidence of benefit with hysteroscopic myomectomy compared to regular fertility-oriented intercourse during 12 months for clinical pregnancy (odds ratio (OR) 2.4, 95% confidence interval (CI) 0.97 to 6.2, P = 0.06, 94 women) and miscarriage (OR 1.5, 95% CI 0.47 to 5.0, P = 0.47, 94 women) (very low-quality evidence). The hysteroscopic removal of polyps prior to IUI increases the odds of clinical pregnancy (experimental event rate (EER) 63%) compared to diagnostic hysteroscopy and polyp biopsy only (control event rate (CER) 28%) (OR 4.4, 95% CI 2.5 to 8.0, P < 0.00001, 204 women, high-quality evidence).

AUTHORS' CONCLUSIONS

Hysteroscopic myomectomy might increase the odds of clinical pregnancy in women with unexplained subfertility and submucous fibroids, but the evidence is at present not conclusive. The hysteroscopic removal of endometrial polyps suspected on ultrasound in women prior to IUI might increase the clinical pregnancy rate. More randomised studies are needed to substantiate the effectiveness of the hysteroscopic removal of suspected endometrial polyps, submucous fibroids, uterine septum or intrauterine adhesions in women with unexplained subfertility or prior to IUI, IVF or ICSI.

Clinical approach for the classification of congenital uterine malformations

A more objective, accurate and non-invasive estimation of uterine morphology is nowadays feasible based on the use of modern imaging techniques. The validity of the current classification systems in effective categorization of the female genital malformations has been already challenged. A new clinical approach for the classification of uterine anomalies is proposed. Deviation from normal uterine anatomy is the basic characteristic used in analogy to the American Fertility Society classification. The embryological origin of the anomalies is used as a secondary parameter. Uterine anomalies are classified into the following classes: 0, normal uterus; I, dysmorphic uterus; II, septate uterus (absorption defect); III, dysfused uterus (fusion defect); IV, unilateral formed uterus (formation defect); V, aplastic or dysplastic uterus (formation defect); VI, for still unclassified cases. A subdivision of these main classes to further anatomical varieties with clinical significance is also presented. The new proposal has been designed taking into account the experience gained from the use of the currently available classification systems and intending to be as simple as possible, clear enough and accurate as well as open for further development. This proposal could be used as a starting point for a working group of experts in the field.

Combined hysteroscopic findings and 3-dimensional reconstructed coronal view of the uterus to avoid laparoscopic assessment for inpatient hysteroscopic metroplasty: pilot study

STUDY OBJECTIVE

To assess the use of 3-dimensional (3D) reconstructed coronal view of the uterus and intraoperative hysteroscopic findings to avoid diagnostic laparoscopy during inpatient hysteroscopic metroplasty.

DESIGN

Pilot study (Canadian Task Force classification II).

SETTING

University hospital infertility clinic.

PATIENTS

Fifty-nine patients with recurrent abortion and double uterine cavity with 3D sonographic diagnosis of septate uterus undergoing inpatient hysteroscopic metroplasty.

INTERVENTIONS

Inpatient hysteroscopic treatment of septate uterus without laparoscopic diagnosis. In addition to sonographic observations, 2 intraoperative hysteroscopic criteria were used to confirm the diagnosis: visualization of muscular fibers and myometrial blood vessels.

MEASUREMENTS AND MAIN RESULTS

Operative parameters (operative time and fluid absorption), complications (incomplete resection and uterine perforation), requirement for a second intervention, and shape of the uterine cavity at hysteroscopic follow-up. In 56 of 59 patients (94.9%), intervention was performed without complications, and in 3 cases, intervention was suspended because of intraoperative suspicion of bicornate uterus. These 3 patients underwent laparoscopy, which confirmed the diagnosis of septate uterus. In all cases, incision was considered sufficient. Postoperative diagnostic hysteroscopy in all patients showed a normal cavity (fundal notch <1 cm).

CONCLUSIONS

Combined use of hysteroscopic confirming criteria and 3D sonography seems to be a reliable and simple strategy for characterizing the presence of septate uterus and to perform inpatient metroplasty usually without laparoscopic visualization of the uterine fundus.

[Hysteroscopic myomectomy using bipolar energy: a gold standard?]

In recent years, hysteroscopic resection has become the treatment of choice for submucous fibroids. Technological advances enabled the use of bipolar resectoscopes, in the same way as new bipolar instruments used in laparoscopy or open surgery. Bipolar systems would be expected to eliminate the risks of hyponatremia and electrical burns. In evaluation studies, bipolar energy used in operative hysteroscopy is as effective in comparison with the unipolar system. However, no clinical study has yet shown increased reliability of bipolar resection to consider their use as a gold standard. Outpatient operative hysteroscopy is now developing rapidly with the introduction of bipolar energy and small-diameter endoscopes. Although the financial impact is unknown, It allows time saving with maximal safety, avoiding cervical dilatation and anesthetic procedures.

The outcomes of hysteroscopy in women with implantation failures after in-vitro fertilization: findings and effect on subsequent pregnancy rates

PURPOSE OF REVIEW

To update information on the findings of hysteroscopy in women with implantation failures after in-vitro fertilization (IVF) as well as on the effect of the procedure on subsequent pregnancy rates.

RECENT FINDINGS

Information from three review publications indicates that the incidence of abnormal hysteroscopic findings in women with repeated implantation failures (RIFs) varies between 25 and 50%, whereas by pooling data from randomized studies, hysteroscopy significantly increases the clinical pregnancy rate (CPR) on the subsequent IVF cycle (pooled RR = 1.57, 95% CI: 1.29-1.92, P < 0.00001). Two recent clinical articles reported that the incidence of abnormal hysteroscopic findings in RIF patients was approximately 37%: the one study reported no differences in CPR between RIF patients with abnormal versus normal hysteroscopy; the second study reported significantly increased CPR in RIF patients with abnormal or treated hysteroscopic findings compared to those with a normal hysteroscopy, as well as in RIF patients having a hysteroscopy compared to controls not having the procedure.

SUMMARY

There is accumulated evidence that hysteroscopy is beneficial for women experiencing implantation failures after IVF. Not only the correction of hysteroscopic findings improves the pregnancy rates, at least when compared to controls not having a hysteroscopy, but also the procedure itself may have a positive prognostic value for achieving a subsequent pregnancy.

[Septate uteri: must we treat all of them?]

Septate uterus is the most common female genital malformation. It can be responsible for recurrent miscarriages and infertility. Hysteroscopic septoplasty is an effective procedure. It can prevent abortions and probably increase fertility. The hysteroscopic section of the septum has become a simple and safe technique, with the use of small hysteroscopes and that of bipolar energy with trained surgeons. These are the reasons why hysteroscopic septoplasty can be proposed to women with septate uterus and a desire for pregnancy.
