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

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.

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.

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.

The Prevalence and Clinical Impact of Adenomyosis in Pregnancy-Related Hysterectomy

Background: The epidemiology of adenomyosis has been traditionally based on patients undergoing hysterectomy for gynecological indications, while its prevalence among hysterectomies performed for obstetric complications is unknown. The aim of this study was to assess the prevalence and clinical impact of adenomyosis diagnosed through histology among women undergoing pregnancy-related hysterectomy (PH). Methods: This was a retrospective cohort study. Women who delivered at a tertiary care regional obstetric hub in Milan between 2009 and 2020 were reviewed to identify cases of PH. Histopathological reports of surgical specimens were examined. Cases with adenomyosis were compared to those without adenomyosis for baseline characteristics, obstetric history and outcomes. Results: During the study period there were 71,061 births and a total of 130 PH, giving a PH incidence of 1.83 per 1000 deliveries. Adenomyosis cases were 18, giving a prevalence of 13.8%. Adenomyosis was associated with placenta previa (77.8 vs. 45.5%, p = 0.01), chorionamnionitis (27.8 vs. 5.4%, p = 0.008), lower gestational age at birth (32 ± 4.6 vs. 35.5 ± 3.6 weeks’ gestation, p = 0.0004), and intrauterine fetal demise among twin pregnancies (50 vs. 4.5%, p = 0.048). Conclusion: Adenomyosis entails a relevant impact on obstetric and perinatal outcomes related to PH. More evidence is needed on the clinical relevance of an ultrasonographic diagnosis of adenomyosis before conception.

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 stepwise approach to robotic assisted excision of a cesarean scar pregnancy

Objective

To develop a stepwise approach to robotic assisted excision of cesarean scar pregnancy (CSP) with metroplasty.

Methods

This illustrative video presentation demonstrating CSP, the criteria for ultrasound diagnosis, and a step-by-step approach for robotic assisted excision of CSP and multi-layer hysterotomy closure at a tertiary medical center.

Results

Robotic assisted resection is a safe and feasible method to treat cesarean scar ectopic pregnancies. Key ultrasonographic characteristics of CSP are highlighted to facilitate its diagnosis, thus allowing for early intervention with a minimally invasive surgical treatment as necessary. Our patient was a 30-year-old gravida 2 para 1 woman with a history of 1 prior-term low transverse cesarean delivery, who presented with vaginal bleeding in the first trimester and was ultimately diagnosed with CSP. After unsuccessful methotrexate therapy, the patient underwent an uncomplicated robotic assisted excision of her CSP and metroplasty in 2 layers using a stepwise approach: Step 1-Creation of a bladder flap; Step 2-Isolation and excision of CSP; Step 3-Hysterotomy closure in 2 layers; and Step 4-Hysteroscopy.

Conclusion

When diagnosed late, cesarean scar ectopic pregnancy can cause a significant hemorrhage from rupture. Early radiologic diagnosis does not only indicate minimally invasive surgery as a treatment option but also assists with related surgical planning. This video demonstrates a stepwise approach to the robotic assisted excision of CSP with metroplasty. With these 4 simple steps, surgical procedure can be safe and efficient.

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.

A septate uterus with double cervix during two pregnancies: pregnancy outcome before and after cervix sparing metroplasty. A case report

In this case report we present a patient with different pregnancy outcomes after IVF treatments. After an extremely premature delivery in her first pregnancy, a vaginal 3D ultrasound scan revealed a correct diagnosis for her uterine anomaly: A complete uterine septum, double cervix and non-obstructive longitudinal vaginal septum, classified as U2bC2V1 according to the European Society of Human Reproduction and EmbryologyEuropean Society for Gynaecological Endoscopy (ESHRE-ESGE)-classification. She underwent a cervix sparing metroplasty and had a spontaneous vaginal birth at 41+2 weeks gesttation. For patients with otherwise unexplained infertility or earlier premature delivery, a diagnostic workup, oriented to the research of uterine malformations, should be taken into consideration.
