Fibroids, infertility and laparoscopic myomectomy

Managing Primary Infertility in a Woman With Uterine Fibroids Utilizing Myomectomy and In Vitro Maturation (IVM) of Oocytes

This case report demonstrates the management of primary infertility in a couple: the male was 37 years old and the female was 32 years old. The female had a submucosal uterine fibroid. Later, the female underwent a myomectomy to remove submucosal fibroids in the uterus after two failed intrauterine insemination (IUI) cycles. After six months of her recovery period, she underwent ovum pickup for an in vitro fertilization (IVF) cycle. During the process of ovum pickup (OPU), four oocytes were retrieved: three in the metaphase one (M1) stage and one in the metaphase two (M2) stage. Subsequently, the couple underwent in vitro maturation (IVM) of oocytes, where the M1 stage oocytes were cultured for six hours. The M1 stage oocytes progressed to the M2 stage. These oocytes were then injected with sperm, which resulted in the formation of two blastocysts. These blastocysts were then cryopreserved for three months, and after three months, these frozen embryos were then transferred, leading to the successful conception. The case study evaluates a couple who suffered from infertility. This study includes a treatment of myomectomy and in vitro maturation.

Ruptured ectopic molar pregnancy and ruptured uterine fibroid: a challenging rare diagnosis

Although rare and unusual occurrences, a ruptured ectopic molar pregnancy (MP) and a ruptured uterine fibroid can lead to significant maternal morbidity and mortality. We present a unique case of these complications developing concurrently-resulting in the haemodynamic compromise of an otherwise healthy young female patient. The patient underwent a diagnostic laparoscopy which converted into a laparotomy, salpingectomy and myomectomy. Comprehensive histopathology confirmed the diagnosis of a ruptured ectopic complete MP and ruptured uterine fibroid. The patient recovered quickly within days. Prompt definitive management, conclusive histopathology and adequate follow-up were the hallmarks of this singular case. These key factors lead to the rare diagnosis of ruptured ectopic MP and uterine fibroid, prevention of adverse outcomes and provision of comprehensive patient care.

Uterine fibroids - Causes, impact, treatment, and lens to the African perspective

Leiomyomas, or uterine fibroids as they are commonly known, are mostly seen in women of reproductive age. However, they can go undetected in most women, and approximately 25% of women show clinical symptoms. Although fibroids are a global burden impacting 80% of premenopausal women, they are more prevalent among Black women than among women of other races. Based on clinical diagnosis, the estimated cumulative incidence of fibroids in women ≤50 years old is significantly higher for black (>80%) versus white women (∼70%). The cause of leiomyomas is not clearly known, but studies have shown evidence of factors that drive the development or exacerbation of the disease. Evidence has linked risk factors such as lifestyle, age, environment, family history of uterine fibroids, and vitamin D deficiencies to an increased risk of uterine fibroids, which impact women of African descent at higher rates. Treatments may be invasive, such as hysterectomy and myomectomy, or non-invasive, such as hormonal or non-hormonal therapies. These treatments are costly and tend to burden women who have the disease. Sub-Saharan Africa is known to have the largest population of black women, yet the majority of uterine fibroid studies do not include populations from the continent. Furthermore, the prevalence of the disease on the continent is not well determined. To effectively treat the disease, its drivers need to be understood, especially with regard to racial preferences. This paper aims to review the existing literature and build a case for conducting future research on African women.

Concurrent gestational trophoblastic neoplasia and large uterine fibroid in a nullipara – Case report

Introduction

The management of a large uterine fibroid concurrent with gestational trophoblastic disease (GTD) in a nullipara is complicated, challenging yet should focus on conserving fertility. We would like to share our experience.

Case description

A 28-year-old G1P0A0 of 10–11 weeks’ gestation presented with a profuse vaginal bleeding with a history of passing swollen, grape-like tissues from the vagina. Since 7 months prior, a large uterine fibroid >10 cm had been diagnosed on ultrasound. Patient was diagnosed with GTD with β-human chorionic gonadotropin (hCG) levels exceeding 1,000,000 mIU/mL. No pulmonary metastases were detected. She underwent a vacuum curettage for her complete hydatidiform mole.Six days later, she underwent an elective myomectomy. Her nulliparity precluded hysterectomy. Post-discharge, her β-hCG levels plateaued and were consistently high over 3 consecutive measurements. A diagnosis of gestational trophoblastic neoplasia (GTN) was established. Patient is currently undergoing a methotrexate-folinic acid rescue chemotherapy regimen due to her having a low risk, stage 1 GTN.

Discussion

Uterine fibroid may reach exceptional sizes. There is so far no link between GTD and uterine fibroids but their concurrent presence is extremely rare. The definitive management for a large fibroid is hysterectomy but considering the patient's nulliparity, a myomectomy was appropriate. GTD's definitive management is vacuum curettage.Periodical β-hCG measurement should follow discharge. Plateauing β-hCG levels indicated GTN and due to her low-risk GTN, she required a single-agent methotrexate chemotherapy. Most patients with low-risk GTN make a complete recovery.

Conclusion

Fertility after myomectomy and GTN generally has an excellent prognosis.

•

Uterine fibroids and gestational trophoblastic disease are rarely encountered together.

•

Managing fibroids and gestational trophoblastic disease in a nullipara should focus on conserving fertility.

•

Fertility after myomectomy is generally excellent.

•

Fertility after chemotherapy for gestational trophoblastic disease is generally excellent.

Single Evaluation of Use of a Mixed Reality Headset for Intra-Procedural Image-Guidance during a Mock Laparoscopic Myomectomy on an Ex-Vivo Fibroid Model

Uterine fibroids represent the highest prevalence of benign tumors in women, with reports ranging from 4.5% to 68.6%, with a significant bias towards African American women. For uterine fibroids, a significant decision is determining whether fibroids can be successfully removed using minimally invasive (MI) techniques or their removal requires open surgery. Currently, the standard-of-care for intra-procedural visualization for myomectomies is ultrasound, which has low image quality and requires a specially trained assistant. Currently, the state-of-the-art is to obtain a pre-procedural MRI scan of the patient, which can be used for diagnosis and pre-procedural planning. Although proven incredibly useful pre-procedurally, MRI scans are not often used intra-procedurally due to the inconvenient visualization as 2D slices, which are seen on 2D monitors that do not intuitively convey the depth or orientation of the fibroids, as needed to effectively perform myomectomies. To address this limitation, herein, we present the use of a mixed reality headset (i.e., Microsoft HoloLens 2), as a tool for intra-procedural image-guidance during a mock myomectomy of an ex vivo animal uterus. In this work, we created a patient-specific holographic rendering by performing image segmentation of an MRI scan of a custom-made uterine fibroid animal model. A physician qualitatively assessed the usefulness of the renderings for fibroid localization, as compared to the same visualization on a 2D monitor. In conclusion, the use of mixed reality as an intra-procedural image guidance tool for myomectomies was perceived as a better visualization technique that could lead to improvements in MI approaches and make them accessible to patients from lower socioeconomic populations.

A Systematic Review of Minimally Invasive Treatments for Uterine Fibroid-Related Bleeding

Newer minimally invasive techniques provide treatment options for symptomatic uterine fibroids while allowing uterus preservation. The objective of this review was to analyze the efficacy of uterine-preserving, minimally invasive treatment modalities in reducing fibroid-related bleeding. A comprehensive search was conducted of PubMed, Embase, PsycINFO, ClinicalTrials.gov, Scopus, and Cochrane Library databases from inception to July 2020. English-language publications that evaluated premenopausal women with fibroid-related bleeding symptoms before and after treatment were considered. Randomized controlled trials were assessed for bias with the established Cochrane Risk of Bias Tool 2.0 and observational studies were assessed for quality under the New Castle-Ottawa Scale guidelines. Eighty-four studies were included in the review, including 10 randomized controlled trials and 74 observational studies. Six studies on myomectomy demonstrated overall bleeding symptom improvement in up to 95.9% of patients, though there was no significant difference between mode of myomectomy. Forty-one studies on uterine artery embolization reported significant reduction of fibroid-related bleeding, with symptomatic improvement in 79 to 98.5% of patients. Three studies suggested that embolization may be superior to myomectomy in reducing fibroid-related bleeding. Six studies reported that laparoscopic uterine artery occlusion combined with myomectomy led to greater reduction of bleeding than myomectomy alone. Fifteen studies demonstrated significantly reduced bleeding severity after radiofrequency ablation (RFA). Additional research is needed to establish the superiority of these modalities over one another. Long-term evidence is limited in current literature for magnetic resonance-guided focused ultrasound surgery, cryomyolysis, microwave ablation, and laser ablation.

Reproductive Outcomes after Laparoscopic Myomectomy: Conventional versus Barbed Suture

STUDY OBJECTIVE

To study the reproductive outcomes after laparoscopic myomectomy comparing conventional (nonbarbed) suture with barbed suture used for myometrial defect closure.

DESIGN

Monocentric retrospective cohort study with prospective follow-up survey for reproductive outcomes conducted in April and May 2020.

SETTING

Tertiary care center (center for advanced gynecologic laparoscopy and infertility).

PATIENTS

Women who underwent laparoscopic myomectomy for uterine leiomyomas from January 2004 to December 2017.

INTERVENTIONS

Laparoscopic myomectomy with closure of the myometrium using either conventional (nonbarbed suture) or barbed suture and follow-up survey regarding reproductive outcomes.

MEASUREMENTS AND MAIN RESULTS

The outcomes measured included the rate of conception, pregnancy complications, mode of delivery, and perioperative complications for both kinds of suture materials used. Of the 399 women who underwent laparoscopic myomectomy, 343 satisfied the inclusion criteria and were followed up; 235 patients responded. A total of 120 patients were included in the nonbarbed group (group A), and 115 patients were included in the barbed group (group B). A total of 182 (group A: 97 vs group B: 85; p = .204) women had actively sought pregnancy postoperatively, of whom 93 (51.09%) in total and 51 (54.8%) in group A vs 42 (45.1%) in group B reported at least 1 pregnancy with no significant difference in the incidence rate ratios between the 2 groups. Of the recorded pregnancies84.9% (group A: 88.2% vs group B: 80.9%) live births, 6.4% (group A: 5.8% vs group B: 7.1%) had first-trimester miscarriages, 2.1% (group A: 1.9% vs group B: 2.3%) had an ectopic pregnancy, and 6 were ongoing pregnancies at the time of the study analysis, which were compared statistically between both study groups. Pregnancy-related complications were noted in 12 of the 93 pregnant women (12.9%), which were comparable in both groups. No case of uterine rupture was reported.

CONCLUSION

Our study supports good reproductive outcomes in women after laparoscopic myomectomy with barbed sutures. Furthermore, the inclusion of nonbarbed sutures as a control group in our study reinforces that barbed sutures in myomectomy are as safe as, and an easier alternative to, conventional sutures without affecting pregnancy outcomes.

Operative and Obstetric Outcomes after Single-port Laparoscopic Myomectomy: A Retrospective Single-center Analysis of 504 Cases

STUDY OBJECTIVE

To analyze the obstetric and operative outcomes of 504 cases of single-port laparoscopic myomectomy (SPLM).

DESIGN

Single-center retrospective study.

SETTING

A tertiary university hospital.

PATIENTS

A total of 502 patients (504 SPLM procedures) who underwent SPLM for symptom relief or growing myomas between October 2009 and April 2020.

INTERVENTIONS

Data on patient demographics, operative variables (estimated blood loss, hemoglobin decrease, operation time, perioperative complications, and postoperative hospital stay), and obstetric outcomes (the surgery-to-pregnancy interval and birth-related outcomes) were obtained from medical records and analyzed.

MEASUREMENTS AND MAIN RESULTS

The mean age of the patients was 40.6 ± 6.6 years. The patients had had an average of 2.3 ± 2.2 myomas removed; the largest myoma size was 6.8 ± 2.4 cm. The mean operation time, postoperative hemoglobin decrease, and postoperative hospital stay duration were 112.9 ± 45.3 minutes, 1.7 ± 1.1 g/dL, and 2.2 ± 1.4 days, respectively. The overall rate of postoperative complications was 7.7% (39/504), and the common complications were transfusions (16/504, 3.1%) or wound problems (15/504, 3.0%). Conversion to multiport or open myomectomy was required in 0.8% of the cases (4/504). A total of 376 women were of child-bearing age, and 56 attempted to become pregnant after surgery. The mean interval from surgery to pregnancy was 15.6 ± 12.2 months. The obstetric outcomes were pregnancy (42/56, 75.0%), live birth (39/56, 69.6%), and miscarriage (2/56, 3.6%). One pregnant woman was lost to follow-up. The 39 live births predominantly involved full-term delivery (36/39, 92.3%), mostly through cesarean section (36/39, 92.3%). No postpartum complications were reported. The 2 most common obstetric complications were preterm labor (7.6%) and gestational diabetes (5.1%).

CONCLUSION

SPLM seems to be an effective procedure with good operative and postoperative obstetric outcomes for women with myomas who require surgery and may wish to subsequently become pregnant.

Infertility and associated factors in three hospitals in Douala, Cameroon: a cross-sectional study

AIM

We determined the prevalence and factors associated with couple infertility in three hospitals in Douala, Cameroon.

METHODS

We conducted a cross-sectional study from December 18th 2015 to March 18th 2016 in three public hospitals in Douala. Three hundred and sixty participants were studied prospectively for associated factors using a multivariate logistic regression model and 4732 files were studied retrospectively for the prevalence of infertility. Statistical significance was set at p < 0.05.

RESULTS

The prevalence of couple infertility was 19.2%. In logistic models, the factors which independently increased the risk of couple infertility were a history of reproductive tract infection/STI, a history of uterine fibroids, a history of dysmenorrhea and abortion for the females while for males it was a history of mumps, erectile dysfunction and exposure to chemicals/toxic substances/pesticides.

CONCLUSION

One in every five couples in this study was infertile. Several factors affect the risks associated with couple infertility. The identification of these factors could help detect subgroups of couples at high risk of infertility. Reproductive health education, screening programmes for STI's that may lead to infertility should be offered to couples.

Perinatal outcomes of women undergoing cesarean delivery after prior myomectomy

Background: The American College of Obstetricians and Gynecologists recommends that women who have had a prior myomectomy that entered the endometrial cavity undergo cesarean delivery in order to avoid the possible complication of uterine rupture. Women with prior myomectomies may also have intraabdominal adhesions, complicating future surgery and if myomas remain after myomectomy, they may have more bleeding complications during their subsequent pregnancies.Objectives: The purpose of this study was to evaluate maternal and neonatal outcomes after prior myomectomy in women undergoing planned cesarean delivery.Study design: We conducted a retrospective cohort study using the Maternal Fetal Medicine Units Cesarean Registry database comparing women undergoing a cesarean delivery with a history of prior myomectomy to women undergoing a cesarean delivery without a history of a prior myomectomy. Inclusion criteria were singleton gestations at term undergoing planned cesarean delivery. Exclusion criteria were stillbirth, cesarean delivery indication for nonreassuring fetal heart rate, macrosomia, abruption, previa or women undergoing planned trial of labor after cesarean. Primary outcome was incidence of blood transfusion. Maternal and neonatal outcomes were compared secondarily. Logistic regression was used to adjust for confounders.Results: The entire study population included 73,257 deliveries; 34,002 women met inclusion criteria, of which 367 had a prior myomectomy and 33,635 were controls. The demographics, which varied by maternal age, race and number of prior cesareans were adjusted for when calculating maternal outcomes. The rate of intraoperative transfusion in the prior myomectomy group was 1.4% (5/367) compared to 0.4% (131/33,635) in the control group (aOR 2.8; 95% CI 1.15-6.79). The prior myomectomy group had a higher incidence of postpartum transfusion rate (2.5%, 9/367) compared to the control group (1.2%, 416/33,635) (aOR 2.03; 1.06-3.92), uterotonic usage (5.4%, 20/367) compared to the control group (3.5%, 1165/33,635; aOR 1.57; 95% CI 1.01-2.45), bowel injury (0.5%, 2/367) compared to the control group (0.0%, 14/33,635; aOR 8.13; 95% CI 2.05-32.28) and cesarean hysterectomy (1.4%, 5/367) compared to the control group (77/33,635; aOR 3.43; 95% CI 1.32-8.91). Neonatal outcomes were not different between groups.Conclusion: Prior myomectomy in women with term, singleton gestations undergoing planned cesarean delivery was associated with an 180% increased risk of intraoperative transfusion compared to the control group. We also found that women in the myomectomy group are 57% more likely to use uterotonics, 713% more likely to experience a bowel injury, 243% more likely to undergo a cesarean hysterectomy, and 227% more likely to need a classical uterine incision during delivery. Neonatal morbidity was not statistically different between the groups.

Long-term outcome of MR-guided focused ultrasound treatment and laparoscopic myomectomy for symptomatic uterine fibroid tumors

BACKGROUND

Fibroid tumors are the most common benign tumors in women of reproductive age. Treatment is usually indicated for those who are symptomatic, with different techniques being used.

OBJECTIVE

The purpose of this study was to compare the long-term outcome of laparoscopic myomectomy with magnetic resonance-guided focused ultrasound for symptomatic uterine fibroid tumors.

STUDY DESIGN

A cohort study was conducted on all patients with symptomatic uterine fibroid tumors who were admitted to a single tertiary care center and treated operatively with laparoscopic myomectomy or treated conservatively with magnetic resonance-guided focused ultrasound from January 2012 until January 2017. Assessment for further interventions and sustained fibroid-associated symptoms was performed, with the use of the Uterine Fibroid Symptom and Quality of Life symptom severity score.

RESULTS

One hundred fifty-four women met the inclusion criteria. Complete follow-up evaluation was achieved for 64 women who underwent laparoscopic myomectomy and for 68 women who were treated by magnetic resonance-guided focused ultrasound. Follow-up time was similar for the 2 groups (median, 31 months [interquartile range, 17-51 months] vs 36 months [interquartile range, 24-41]; P=.95). The rate of additional interventions was 5 (7.8%) and 9 (13.2%), respectively (P=0.312). Similarly, the Uterine Fibroid Symptom and Quality of Life symptom severity score questionnaire score at follow-up interviews revealed comparable median scores of 17 (interquartile range, 12-21) vs 17 (interquartile range, 13-22) for laparoscopic myomectomy and magnetic resonance-guided focused ultrasound, respectively (P=.439). Analysis of each of the symptoms separately (bleeding, changes in menstruation, abdominal pain, bladder activity, nocturia, fatigue) did not change these findings, nor did a multivariate analysis.

CONCLUSION

Satisfaction with long-term outcome and rate of reinterventions after magnetic resonance-guided focused ultrasound treatment or laparoscopic myomectomy for uterine fibroid tumors was comparable. Further larger randomized trials are needed to confirm these findings.

Improved Fertility Following Enucleation of Intramural Myomas in Infertile Women

Background:

The relationship between intramural myomas and fertility remains unclear. The main debate rests on whether cavity-distorting intramural myomas (CDMs) adversely affect fertility more than non-CDMs. We aimed to compare the effects of enucleating non-CDMs and CDMs on fertility improvement in females with unexplained infertility.

Methods:

We prospectively recruited 83 women undergoing myomectomy for unexplained infertility with intramural myomas between June 2008 and November 2012 and classified them into non-CDMs group (n = 45) and CDMs group (n = 38). We then compared postoperative infertility rates, spontaneous pregnancy rates, pregnancy outcomes, live birth rates, and obstetric complications. For continuous variables, we calculated the mean ± standard deviation, median and interquartile range, and analyzed the data using Student's t-test and the Mann-Whitney U-test. For categorical variables, the Pearson's Chi-square test, the continuity correction test, and Fisher's exact test were used.

Results:

Patients’ demographics and myoma characteristics were comparable between the two groups. The overall spontaneous pregnancy rate increased from 0% to 68.42% following myomectomy. The postoperative infertility rate was significantly higher in the non-CDMs group than that in the CDMs group (50.00% vs. 23.53%, t = 5.579, P = 0.018), whereas the postoperative spontaneous pregnancy rate was significantly lower in the non-CDMs group than that in the CDMs group (47.62% vs. 70.59%, t = 4.067, P = 0.044). Compared with the enucleation of non-CDM, the enucleation of CDM patients was a protective factor for the fertility restoration (risk ratio [RR] = 3.717, 95% confidence interval [CI]: 1.284–10.753, P = 0.015), although postoperative fertility restoration declined with age (RR = 1.141, 95% CI: 1.005–1.295, P = 0.041).

Conclusions:

Intramural myomas are associated with impaired fertility. Women experiencing unexplained infertility, and possessing intramural myomas, have a better chance of conception following myomectomy, and these benefits are more obvious for younger patients and patients with CDM.

Patency of uterine wall in pregnancies following assisted and spontaneous conception with antecedent laparoscopic and abdominal myomectomies - a difficult case and systematic review

A case of uterine rupture at 24 weeks in a pregnancy succeeding myomectomy and triple embryo transfer is described and literature is reviewed systematically to evaluate the importance of uterine rupture in pregnancies after myomectomy in general and some important sub-populations. Systematic search identified 179 papers and following a strategical selection process 45 studies were analyzed in detail, including 6 cohort and 19 observational studies, 3 case series and 17 case reports. Comparison of risk of uterine rupture after abdominal and laparoscopic myomectomy is made. In pregnancies after IVF number of embryos transferred are determined. Optimal contraceptive intervals and surgical techniques are discussed. The consequences of these observations are analyzed and conclusions are made which can assist individualizing treatment options and improve patient selection.

A Fast 3-Dimensional Magnetic Resonance Imaging Reconstruction for Surgical Planning of Uterine Myomectomy

BACKGROUND

Uterine myoma is the most common benign gynecologic tumor in reproductive-aged women. During myomectomy for women who want to preserve fertility, it is advisable to detect and remove all myomas to decrease the risk of additional surgery. However, finding myomas during surgery is often challenging, especially for deep-seated myomas. Therefore, three-dimensional (3D) preoperative localization of myomas can be helpful for the surgical planning for myomectomy. However, the previously reported manual 3D segmenting method takes too much time and effort for clinical use. The objective of this study was to propose a new method of rapid 3D visualization of uterine myoma using a uterine template.

METHODS

Magnetic resonance images were listed according to the slide spacing on each plane of the multiplanar reconstruction, and images that were determined to be myomas were selected by simply scrolling the mouse down. By using the selected images, a 3D grid with a slide spacing interval was constructed and filled on its plane and finally registered to a uterine template.

RESULTS

The location of multiple myomas in the uterus was visualized in 3D and this proposed method is over 95% faster than the existing manual-segmentation method. Not only the size and location of the myomas, but also the shortest distance between the uterine surface and the myomas, can be calculated. This technique also enables the surgeon to know the number of total, removed, and remaining myomas on the 3D image.

CONCLUSION

This proposed 3D reconstruction method with a uterine template enables faster 3D visualization of myomas.

Structured vs narrative reporting of pelvic MRI for fibroids: clarity and impact on treatment planning

OBJECTIVES

To evaluate clarity and usefulness of MRI reporting of uterine fibroids using a structured disease-specific template vs. narrative reporting for planning of fibroid treatment by gynaecologists and interventional radiologists.

METHODS

This is a HIPAA-compliant, IRB-approved study with waiver of informed consent. A structured reporting template for fibroid MRIs was developed in collaboration between gynaecologists, interventional and diagnostic radiologists. The study population included 29 consecutive women who underwent myomectomy for fibroids and pelvic MRI prior to implementation of structured reporting, and 42 consecutive women with MRI after implementation of structured reporting. Subjective evaluation (on a scale of 1-10, 0 not helpful; 10 extremely helpful) and objective evaluation for the presence of 19 key features were performed.

RESULTS

More key features were absent in the narrative reports 7.3 ± 2.5 (range 3-12) than in structured reports 1.2 ± 1.5 (range 1-7), (p < 0.0001). Compared to narrative reports, gynaecologists and radiologists deemed structured reports both more helpful for surgical planning (p < 0.0001) (gynaecologists: 8.5 ± 1.2 vs. 5.7 ± 2.2; radiologists: 9.6 ± 0.6 vs. 6.0 ± 2.9) and easier to understand (p < 0.0001) (gynaecologists: 8.9 ± 1.1 vs. 5.8 ± 1.9; radiologists: 9.4 ± 1.3 vs. 6.3 ± 1.8).

CONCLUSION

Structured fibroid MRI reports miss fewer key features than narrative reports. Moreover, structured reports were described as more helpful for treatment planning and easier to understand.

KEY POINTS

• Structured reports missed only 1.2 ± 1.5 out of 19 key features, as compared to narrative reports that missed 7.3 ± 2.5 key features for planning of fibroid treatment. • Structured reports were more helpful and easier to understand by clinicians. • Structured template can provide essential information for fibroids treatment planning.

Outcome of magnetic resonance-Guided focused ultrasound surgery (MRgFUS) for FIGO class 1 fibroids

OBJECTIVE

Intracavitary uterine fibroids and fibroids that distort the uterine cavity are associated with excessive vaginal bleeding and infertility. While intracavitary fibroids smaller than 4 cm are usually treated safely by operative hysteroscopy, larger fibroids may require multiple surgeries or more extensive surgery with possible damage to the integrity of the uterine wall. Magnetic resonance-guided focused ultrasound surgery (MRgFUS) is a noninvasive approach for treating uterine fibroids, mainly the intramural type. We present the outcome of MRgFUS treatment for intracavitary fibroids (FIGO class 1) in cases that could not be treated by hysteroscopy due to either fibroid size or patient refusal. (Canadian Task Force II-1).

STUDY DESIGN

A retrospective cohort study from a single tertiary referral center. A total of 68 patients were treated by MRgFUS for symptomatic uterine fibroids from January 2013 to December 2016. Six of them had FIGO class 1 fibroids. Adverse effects and short- and long-term outcomes (quality of life issues and need for additional surgical intervention) were assessed during ambulatory clinic visits and by phone interviews.

RESULTS

The mean ± SD fibroid volume on MRI screening was 86.3 ± 60.9 cm³. Six of those patients underwent the procedure (mean age 40.5 ± 5.6 years, range 33-48). The follow-up duration was 24.1 ± 12.0 months. Four patients were not interested in future fertility and did not undergo additional treatment, while the two who planned to conceive underwent another surgical intervention (one underwent operative hysteroscopy after reduction of fibroid size and the other underwent laparoscopic myomectomy).

CONCLUSION

This preliminary study shows that MRgFUS can be a feasible treatment option for FIGO class 1 uterine fibroids. Shrinkage of fibroids by MRgFUS can obviate or facilitate subsequent surgical intervention in selected cases.

Effect of Non-Cavity Distorting Intramural Fibroids on Assisted Reproduction Outcomes: A Cohort Study

Introduction

The impact of uterine fibroids on fertility and the beneficial role of surgery is controversial. Current data suggest that submucosal and intramural fibroids that distort the endometrial cavity decrease pregnancy and implantation rates. However, the impact of intramural fibroids without intracavitary component is unclear. The aim of this study is to clarify the impact of the uterine myomas and myomectomy in patients undergoing assisted reproductive techniques (ART).

Methods

Retrospective cohort study performed in Instituto Universitario Dexeus including 1072 cycles of IVF performed in infertile patients: 473 in patients with uterine myomas not treated before ART, 79 in patients undergoing ART after myomectomy and 520 in patients included as a control group.

Results

Our results show that there is a significant 64% reduction in the clinical pregnancy rate in women with cavity-distorting intramural fibroids, a 51% significant reduction in the clinical pregnancy rate and a 53% significant reduction in the delivery rate in patients with non-distorting intramural fibroids.

Conclusions

Our study supports the opinion that non-cavity distorting intramural fibroids have a detrimental effect on live births, clinical pregnancy, implantation and delivery rates in patients undergoing ART.

Pregnancy Outcomes and Risk Factors for Uterine Rupture After Laparoscopic Myomectomy: A Single-Center Experience and Literature Review

STUDY OBJECTIVE

To evaluate pregnancy outcomes after laparoscopic myomectomy (LSM), focusing on the risk of uterine rupture.

DESIGN

Retrospective cohort study (Canadian Task Force classification III).

SETTING

University hospital.

PATIENTS

Of 676 women who visited the obstetrics department for a pregnancy after undergoing LSM performed at the same center between 1994 and 2012, we included the 523 women who had follow-up through the end of pregnancy.

INTERVENTIONS

All patients underwent LSM, and their medical charts were retrospectively reviewed.

MEASUREMENTS AND MAIN RESULTS

Multiple myomas were removed in 35.2% of cases, intramural-type lesions occurred in 46.5% of cases, and the mean myoma diameter was 4.9 cm. Pregnancy outcomes after LSM included 400 (76.5%) full-term deliveries and 100 (19.1%) vaginal deliveries, with other adverse outcomes being no different than the general population. The mean interval between LSM and pregnancy was 14 months, and only 3 (0.6%) cases of uterine rupture occurred during pregnancy. In analysis, by reviewing the published cases of uterine rupture, we found that the mean diameter, myoma number and type, and the rate of uterine suture were similar between the ruptured cases and all of our cases of LSM.

CONCLUSION

LSM can be safely used in women of reproductive age who want to become pregnant. Uterine rupture occurs in rare cases, regardless of myoma features, but further large-scale studies are required to ascertain the detailed effects of various surgical techniques.

Uterine fibroids: current perspectives

Uterine fibroids are a major cause of morbidity in women of a reproductive age (and sometimes even after menopause). There are several factors that are attributed to underlie the development and incidence of these common tumors, but this further corroborates their relatively unknown etiology. The most likely presentation of fibroids is by their effect on the woman's menstrual cycle or pelvic pressure symptoms. Leiomyosarcoma is a very rare entity that should be suspected in postmenopausal women with fibroid growth (and no concurrent hormone replacement therapy). The gold standard diagnostic modality for uterine fibroids appears to be gray-scale ultrasonography, with magnetic resonance imaging being a close second option in complex clinical circumstances. The management of uterine fibroids can be approached medically, surgically, and even by minimal access techniques. The recent introduction of selective progesterone receptor modulators (SPRMs) and aromatase inhibitors has added more armamentarium to the medical options of treatment. Uterine artery embolization (UAE) has now been well-recognized as a uterine-sparing (fertility-preserving) method of treating fibroids. More recently, the introduction of ultrasound waves (MRgFUS) or radiofrequency (VizAblate™ and Acessa™) for uterine fibroid ablation has added to the options of minimal access treatment. More definite surgery in the form of myomectomy or hysterectomy can be performed via the minimal access or open route methods. Our article seeks to review the already established information on uterine fibroids with added emphasis on contemporary knowledge.

Patients' age, myoma size, myoma location, and interval between myomectomy and pregnancy may influence the pregnancy rate and live birth rate after myomectomy

OBJECTIVE

To investigate which clinical characteristics will influence the pregnancy rate and live birth rate after myomectomy.

SUBJECTS AND METHODS

Data of clinical characteristics and reproductive outcome from 471 patients who wished to conceive and who underwent abdominal or laparoscopic myomectomy in the Obstetrics and Gynecology Hospital of Fudan University from January 2008 to June 2012 were retrospectively analyzed.

RESULTS

Average age in the pregnancy group (30.0±3.7 years) and the nonpregnancy group (31.2±4.1 years) was statistically different (P=.000). The diameter of the biggest myoma had a positive relationship with the pregnancy rate when it was <10 cm (rs=0.095, P=.039). Abortions before myomectomy, operation type, number, location, and classification of myomas, uterine cavity penetration, and uterine volume seemed not to influence the pregnancy rate (P>.05). The location of the myoma may influence the live birth rate after myomectomy (rs=0.198, P=.002). Anterior and posterior myomas were associated with higher live birth rates than other locations (P=.001). The average interval between myomectomy and pregnancy was 16.0±8.7 months, and there was no difference between the abdominal (17.2±8.6 months) and laparoscopic (15.2±8.8 months) groups (P=.102). The interval in the live birth group was 15.0±8.4 months, and that in the non-live birth group was 18.9±9.3 months; the difference was significant (P=.005).

CONCLUSIONS

Patients' age, myoma size and location, and interval between myomectomy and pregnancy may influence the pregnancy rate and live birth rate after myomectomy.

Spontaneous rupture of uterus in midtrimester pregnancy due to increased uterine pressure with previous laparoscopic myomectomy

Uterine rupture is a life threatening condition for both the mother and her fetus. It may be seen in the second trimester usually after induction for pregnancy termination in a scarred uterus. Spontaneous rupture in the second trimester before labor is a very rare condition. Here, we report a case of uterine rupture at 23-week pregnancy due to elevated uterine pressure with a history of laparoscopic myomectomy one year before admission. She was symptomatic for diffuse abdominal pain and the ultrasonographic image was interpreted as amniotic band. Four days later, because of deterioration of the patient and fetal bradycardia urgent laparotomy was performed. Fundal rupture with fibrotic borders suggested that a chronic event was seen. Laparoscopic myomectomy has advantages over laparatomy but the possibility of uterine rupture in following pregnancies should not be underestimated. Therefore, repair of the myometrium should be carefully assessed.
