Myoma and myomectomy: Poor evidence concern in pregnancy

Preterm birth and uterine fibroid necrosis: The clinical presentation illustrated in a case series

OBJECTIVE

Uterine fibroids increase the risk of preterm birth. The current study highlights uterine fibroid necrosis as a possible cause of (extreme) preterm birth.

STUDY DESIGN

Retrospective cohort study in one Dutch academic hospital. Cases were selected from the 526 participants of the MyoFert study (Netherlands Trial Register, NL7990), which included patients who presented between 2004 and 2018 and were between the age of 18 and 45 years at the time of diagnosis of uterine fibroids. Of these participants, 414 women became pregnant. A retrospective chart review of the first pregnancies was performed. The main outcomes were (imminent) preterm birth and signs of fibroid necrosis on ultrasound. In women with signs of fibroid necrosis, the following data were collected systematically: fibroid characteristics, clinical presentation, pregnancy outcome, and postpartum period.

RESULTS

In total, 66 women had a preterm birth (16 %, 66/414), of which 25 pregnancies ended between 16 and <24 weeks (38 %, 25/66) and 41 pregnancies ended between 24 and <37 weeks of gestation (62 %, 41/66). Of all women with preterm birth and available ultrasound images, 15 % (7/48) had fibroid necrosis at the time of labour. These seven patients, supplemented with three patients with fibroid necrosis during their first pregnancy and at least one episode of imminent preterm birth, are described in more detail. In these ten patients, the fibroids increased substantially in size during the first and second trimester, leading to severe abdominal pain in all patients and hospital admission in seven patients. Ultrasound examination of the fibroids showed heterogenic changes and focal transonic areas in the fibroid, which are characteristics that indicate fibroid necrosis. In four patients, myomectomy was performed and necrosis was confirmed histologically.

CONCLUSION

Fibroid necrosis during pregnancy is likely associated with (imminent) preterm birth. Clinicians are advised to structurally evaluate the myometrium in pregnancy, specifically in women presenting with abdominal pain in the second trimester.

Navigating Pregnancy With Uterine Fibroids: A Case Study

Benign uterine tumors, known as leiomyomas or uterine fibroids, can result in severe pain, bleeding, and infertility. They impact a woman's overall well-being, ability to conceive, and the course of her pregnancy. Fibroids are associated with increasing maternal age. When a patient with fibroids is considering pregnancy, ultrasonography and a detailed pelvic examination should be performed to determine the size and location of any fibroids. This case study details a 30-year-old female patient who had fibroids during her pregnancy and responded well to treatment.

Associations between the time interval from myomectomy to subsequent pregnancy and the obstetric outcomes: A population-based cohort study

OBJECTIVE

To investigate the associations between time interval from myomectomy to pregnancy (TIMP) and subsequent pregnancy and obstetric complications, and to explore whether these associations vary according to maternal age at birth.

METHODS

A retrospective population-based cohort study was conducted from 2008 to 2017. Data were extracted from the National Health Insurance Research Database and the Taiwan Maternal and Child Health Database, comprising 2024 379 births from 1 391 856 pregnancies. Eligible cases were identified using diagnostic and procedure codes; 4006 first singleton births in 4006 women after their first laparotomic myomectomy were identified. We estimated the risks of pregnancy and obstetric outcomes according to TIMP (<6, 6-11, and ≥12 months). Subgroup analysis was performed by further dividing according to maternal age at birth (18-34 vs ≥35 years old).

RESULTS

We observed higher risks of gestational hypertensive disorders (adjusted odds ratio [aOR] 1.97, 95% confidence interval [CI] 1.22-3.18, P = 0.005) and neonatal death (aOR 4.59, 95% CI 1.49-14.18, P = 0.008) for TIMP of <6 months versus TIMP of 6-11 months. Likewise, a TIMP ≥12 months was associated with increased risks of gestational hypertensive disorders (aOR 1.72, 95% CI 1.14-2.58, P = 0.010), and neonatal death (aOR 3.27, 95% CI 1.16-9.24, P = 0.025) versus a TIMP of 6-11 months. In subgroup analysis, women over 35 years old still had higher risks of gestational hypertensive disorders when TIMP was <6 months (aOR 2.26, 95% CI 1.17-4.37, P = 0.015) or ≥12 months (aOR 2.04, 95% CI 1.17-3.54, P = 0.012), and a higher risk of neonatal death when TIMP was <6 months (aOR 4.05, 95% CI 1.06-15.53, P = 0.041); whereas women aged 18-34 years old did not.

CONCLUSIONS

This study suggests that a TIMP between 6 and 11 months is associated with lower risks of gestational hypertensive disorders and neonatal death compared with a TIMP <6 months or ≥12 months, especially for women over 35 years old.

Cesarean Myomectomy: Reflections on Clinical and Surgical Controversies between a New Trans-Decidual Technique vs. Traditional Method

Up to 70-80% of women of reproductive age may be affected with the most common uterine tumors, known as fibroids or myomas. These benign tumors are the second most prevalent cause of surgery among premenopausal women. Predictions show that the occurrence of myomas in pregnancy will increase, and that the risk of having myomas during pregnancy increases with advanced maternal age. Although most women with fibroids do not experience any symptoms during pregnancy, up to 30% of women experience problems during pregnancy, childbirth, and the puerperium. The viability of myoma excision during cesarean surgery (CS) is a contentious issue raised by the rising incidence of myomas in pregnancy and CS rates. A new surgical procedure for removing fibroids using a trans-endometrial approach, which involves making an incision through the decidua itself, has put into doubt the long-standing practice of cesarean myomectomy (CM) with a trans-serosal approach. Some authors have recently advocated for this last approach, highlighting its advantages and potential uses in real-world situations. The purpose of this paper is to critique the present approach to cesarean myomectomy by analyzing the clinical and surgical distinctions between the two approaches and providing illustrations of the CM methods.

Cystic Adenomyoma in Pregnancy: A Case Report

Cystic adenomyomas (CA) are rare. They primarily affect adolescents and young women in their fertile years. Therefore, fertility and pregnancy outcome are of pivotal relevance in this patient collective. Apart from the guidelines of the European Society of Human Reproduction and Embryology (ESHRE) on the management of endometriosis in general, there are no specific treatment recommendations for CA and, as far as our research shows, no data illustrating the behavior of a CA over the course of pregnancy. Thus, we report the case of a 32-year-old 1-gravida, 1-para, preconceptionally diagnosed with a CA by ultrasound. After thoroughly discussing further treatment options, the decision was made to opt for a more conservative approach and not perform surgery before attempting a next pregnancy. The patient conceived spontaneously and sonographic monitoring of the CA throughout pregnancy showed complete regression of the cystic component during the second trimester. A healthy baby was delivered at term by an uncomplicated elective cesarean section. Following a review of the literature and taking into account the course of our case, we propose the feasibility of a conservative, non-surgical approach in women with a CA and the desire to conceive.

Antenatal myomectomy of huge pedunculated fibroid

A female patient in her 20s presented at 10 weeks of pregnancy with abdominal pain. She was known to have a 17-cm fibroid a year ago, which, on repeat imaging, was found to have increased in size to 29 cm. A 12-cm increase in size over a year therefore led to concerns that it would increase in pregnancy, causing risk of thrombosis, decrease in venous return, miscarriage, fibroid torsion, fibroid necrosis, preterm labour and uterine rupture. Following a multidisciplinary team review with obstetricians, neonatologists, gynaecologists and radiologists, the patient opted to proceed with an open myomectomy at 14 weeks gestation, which was performed successfully. The pregnancy continued uneventfully until term when she delivered a healthy girl infant at 38+2 weeks via an elective caesarean section.

Exploring Surgical Strategies for Uterine Fibroid Treatment: A Comprehensive Review of Literature on Open and Minimally Invasive Approaches

Background and Objectives: Uterine myomas represent one of the most prevalent pathologies affecting the female population. These benign neoplasms originate from the smooth muscular cells of the uterus, and they can be either single or multiple. Often associated with debilitating symptoms such as pelvic heaviness, pain, constipation, and urinary dysfunctions, the surgical management of myomectomy exhibits considerable variability. This diversity in approaches is influenced by factors such as the number and size of myomas, the patient's age, and overall clinical conditions. This study aims to elucidate and compare the advantages and disadvantages of different surgical approaches, specifically endoscopic procedures versus open surgery, providing valuable insights for clinical decision making. Materials and Methods: A comprehensive bibliographic search spanning from 2013 to 2023 was systematically conducted across databases including Medline, Embase, the Cochrane Database of Systematic Reviews, and ClinicalTrials.gov. The search utilized keywords such as "myomectomy laparoscopic and open", "myomectomy open and minimally invasive", "myomectomy open and laparoscopic", and "myomectomy open vs. laparoscopic." The research methodology, along with predetermined inclusion and exclusion criteria, was established prior to the search, ensuring a systematic and rigorous approach. Subsequently, data analysis was carried out. Results: Following the study selection process, 25 articles met the eligibility criteria for inclusion in this analysis. The average numbers of myomas were 3.7 (ranging from 1 to 13.7) and 5.4 (ranging from 1 to 13.5) for the minimally invasive surgery and open surgery groups, respectively. In terms of myoma size, the total averages across studies were 7 cm (ranging from 4.8 to 14) for the minimally invasive group and 8 cm (ranging from 3.9 to 11.2) for the open surgery group. The average pregnancy and delivery rates were 29.7% (ranging from 1.8 to 100) for the minimally invasive group and 28.5% (ranging from 1.8 to 100) for the open surgery group. Regarding complications, the average rate was 14.2% (ranging from 0 to 50) for the endoscopic group and 22.3% (ranging from 0 to 60.3) for the laparotomic group. Conclusions: In conclusion, a critical factor influencing the choice of surgical approach is primarily the size and quantity of fibroids. The mini-laparotomic approach emerges as a viable alternative to endoscopy, demonstrating favorable surgical outcomes and aesthetic results. Interestingly, the type of surgical procedure appears to have no significant impact on the pregnancy rate.

Women's experiences of birth and birth options counselling after laparoscopic or open myomectomy

There is emerging evidence that vaginal birth after open and laparoscopic myomectomy may be safe in many pregnancies, however, there are no studies examining the perspectives of women who have given birth post myomectomy and their preferences regarding mode of birth. We performed a retrospective questionnaire survey of women who had an open or laparoscopic myomectomy followed by a pregnancy within 3 maternity units in a single NHS trust in the UK over a 5-year period. Our results revealed only 53% felt actively involved in the decision making for their birth plan and 90% had not been offered a specific birth options counselling clinic. Of those who had either a successful trial of labour after myomectomy (TOLAM) or elective caesarean section (ELCS) in the index pregnancy, 95% indicated satisfaction with their mode of birth however, 80% would prefer vaginal birth in a future pregnancy. Whilst long term prospective data is required to fully establish the safety of vaginal birth after laparoscopic and open myomectomy, this study is the first to explore the subjective experiences of women who had given birth post laparoscopic or open myomectomy and has highlighted the inadequate involvement of these women in the decision-making process.IMPACT STATEMENTWhat is already known on this subject? Fibroids are the commonest female solid tumours in women of childbearing age with surgical management including open and laparoscopic excision techniques. However, the management of a subsequent pregnancy and birth remains controversial with no robust guidance on which women may be suitable for vaginal birth.What do the results of this study add? We present the first study to our knowledge which explores women's experiences of birth and birth options counselling after open and laparoscopic myomectomy.What are the implications of these findings for clinical practice and/or further research? We provide a rationale for using birth options clinics to facilitate an informed decision-making process and highlight the current inadequate guidance for clinicians on how to advise women having a pregnancy following a myomectomy. Whilst long term prospective data is required to fully establish the safety of vaginal birth after laparoscopic and open myomectomy, this needs to be carried out in a way which promotes the preferences of the women affected by this research.

Outcomes of Laparotomic Myomectomy during Pregnancy for Symptomatic Uterine Fibroids: A Prospective Cohort Study

Background: The incidence of pregnant women with uterine fibroids is increasing. As they are reactive to hormonal stimuli, in some cases, uterine fibroids tend to grow during pregnancy and potentially generate symptoms with different levels of severity, causing maternal-fetal complications. In very select cases, when other treatment strategies fail to manage symptoms and there is a substantial risk of adverse pregnancy outcomes, a surgical approach during pregnancy may be considered. Methods: From 2016 to 2021, the data from 28 pregnant women with symptomatic uterine fibroids who underwent laparotomic myomectomy during pregnancy were prospectively collected, and operative and maternal-fetal outcomes were analyzed (ClinicalTrial ID: NCT06009562). Results: The procedure was carried out between 14 and 16 weeks of pregnancy. Four (14.3%) patients had intraoperative complications (miscarriages) and nine (32.1%) had postoperative complications (threatened preterm birth). Overall, 24 (85.7%) women delivered at full term (mean: 38.2 gestational weeks), more than half (n = 13; 54.2%) by vaginal delivery, with normal fetal weights and 1 and 5 min Apgar scores. Conclusions: Laparotomic myomectomy during pregnancy can be considered in selected cases for uterine fibroids with severe symptoms when other treatment options have failed and there is high risk of adverse maternal-fetal outcomes.

Perinatal Outcomes of Pregnancy in Women with Scarred Uteri

Objective

Uterine scarring is risky for the pregnancy and is closely associated with adverse pregnancy outcomes. Here, we investigated risk factors and associated perinatal outcomes in singleton pregnant women with uterine scars.

Methods

This retrospective cohort study was conducted on singleton pregnant women who delivered at the West China Second University Hospital between January 1, 2021, and December 31, 2021.

Results

The control group included 13,433 cases without uterine scars. The study group involved 2397 cases with one previous cesarean delivery (PCD), 163 cases with two PCDs, 12 cases with three PCDs, and 184 cases with non-cesarean uterine scars. The study group had a significantly higher incidence of placenta previa (6.4%), placenta percreta (5.3%), preterm delivery (10.3%), postpartum hemorrhage (3.4%), uterine rupture (9.4%), hysterectomy (0.18%), and bladder injury (0.4%) when compared with the control group (P <0.05). The scarred uterus cases with 1, 2, or 3 PCDs had significantly different complications, with the higher PCD frequency correlating with increased rates of placenta previa, placenta percreta, postpartum hemorrhage, uterine rupture, and uterine resection. Moreover, the hospitalization time, cesarean operation time, and intrapartum bleeding in the current pregnancy significantly increased with increasing PCD frequency (P <0.05). Analysis of the association between the duration of the interval between PCD and re-pregnancy and pregnancy complication revealed that the incidence of pernicious placenta previa was statistically higher in cases with intervals of <2 years or ≥5 years (4.7%) than in cases with 2 years ≤ interval time <5 years (2.5%) (P <0.05).

Conclusion

Pregnancies with uterine scars may experience higher rates of adverse perinatal outcomes. This calls for increased observation during pregnancy and delivery to reduce maternal and fetal complications.

Magnetic resonance imaging findings of spontaneous pyomyoma in a premenopausal woman managed with myomectomy: A case report

BACKGROUND

Acute fibroid complications are rare. However, failure to recognize and treat acute complications expeditiously when they occur can lead to catastrophic, even deadly, complications. Pyomyoma is a rare but potentially fatal condition resulting from infarction and infection of a fibroid through bacterial seeding and direct, hematogenous, or lymphatic dissemination. Even though the diagnosis is established through clinical and laboratory findings, imaging is an important complementary method to support the suspected diagnosis.

CASE SUMMARY

Herein, we report a case of a pyomyoma in a nulliparous woman previously diagnosed with uterine leiomyomatosis according to ultrasound findings. The patient had previously attended the emergency room due to hypogastric pain unresponsive to analgesics. After a week of persistent pain, she developed sepsis without any identifiable foci. Magnetic resonance imaging revealed findings compatible with uterine myomatosis with red degeneration, and a possible diagnosis of a pyomyoma was made according to the imaging findings along with the patient’s clinical features. We decided to perform myomectomy (which is an infrequently performed surgical treatment due to the procedure’s intrinsic implications) due to the patient’s desire to preserve fertility. Histopathologic results revealed a uterine leiomyoma with coagulative and liquefactive necrosis, while the tissue culture showed gram-negative cocci bacteria, which were successfully treated using antibiotic therapy. The patient’s health status improved after several days.

CONCLUSION

The main diagnostic tools to evaluate pyomyomas are the clinical and laboratory findings as well as tissue cultures. Nonetheless, magnetic resonance imaging can help to corroborate these findings as well as to better characterize myomas with its different complications.

Towards a clinical consensus on the management of pregnancy and birth after laparoscopic and open myomectomy: A survey of obstetricians and gynaecologists

OBJECTIVES

The primary aim was to assess if a clinical consensus regarding the management of pregnancy post myomectomy existed amongst consultant obstetricians and gynaecologists. Secondary objectives were to evaluate factors which influence the clinician's decision making in this group of women.

STUDY DESIGN

Electronic survey sent to all consultants working in the North Central and East London deanery, Kent Surrey and Sussex deanery and Imperial NHS Trust to assess opinions on mode of birth post myomectomy, intervals advised to pregnancy post myomectomy, factors influencing the management of delivery in the scarred uterus post myomectomy, opinions on induction of labour and questions relating to operative notes.

RESULTS

209 consultant responses received between 07/03/2022-07/05/2022 (44% response rate); 77% (161/209) practicing obstetricians and gynaecologists, 10% (21/109) pure gynaecologists and 13% (27/209) pure obstetricians. The majority would support a vaginal birth after open myomectomy (75%) and laparoscopic myomectomy (79%). No consensus was found as to the optimal time interval between myomectomy and pregnancy. Higher frequency of performing myomectomy and a greater level of experience were significantly associated with a shorter interval to pregnancy advised. The most important operative factors influencing decision to support trial of labour post myomectomy were breach of uterine cavity; location of fibroids removed and number of incisions on the uterus. 77% believe women should be given a choice regarding mode of delivery post myomectomy in a similar way to previous LSCS. 82.8% would support enrolment of patients into a prospective trial to investigate delivery post myomectomy.

CONCLUSIONS

We present a comprehensive survey of clinician opinions on pregnancy post myomectomy demonstrating that the majority of consultant obstetricians and gynaecologists sampled would support vaginal birth post myomectomy; counselling patients in a similar way to VBAC; a standardised myomectomy operation note and enrolment of patients in a future prospective trial. Wide variation in opinion regarding interval to pregnancy post myomectomy has been highlighted. We believe this information will facilitate counselling discussions and empower women with subsequent pregnancies after myomectomy to make an informed decision on mode of birth post myomectomy.

Pregnancy With Uterine Fibroids: Obstetric Outcome at a Tertiary Care Hospital of Central India

BACKGROUND

Uterine fibroids are the most frequent benign tumor of the female reproductive system, with a significantly lower frequency in pregnancy. This could be due to the fact that uterine fibroids are linked to infertility and low implantation rates following in vitro fertilization (IVF). The goal of this study was to look at the obstetrics outcomes of uterine fibroids and their consequences in a tertiary hospital.

MATERIALS AND METHODS

The current study was a observational cohort study that evaluated the cases of pregnancy with fibroid. Study was undertaken at the Department of Obstetrics and Gynecology (OBGY) at a medical college in central India and it was conducted over a period of nine months from 1st November 2021 to 31st July 2022. All pregnant women who had an ultrasonography (USG)-documented uterine fibroid diagnosed prenatally or antenatally were enrolled. All demographic information, laboratory and USG results were noted and their mode of delivery, obstetric complications, if any, and neonatal outcomes were evaluated.

RESULTS

A total of 110 cases were enrolled as per inclusion and exclusion criteria. The majority of patients (42.73%) were in the 26- to 30-year-old age group. In this study, the majority of cases were carried to term (80.9%). The most prevalent mode of delivery was caesarean section (61.82%). Major complications during pregnancy were threatened preterm labor (21.82%), and blood transfusion (20.00%), whereas postpartum hemorrhage (PPH) occurred in 9.09% cases, and 47 patients (42.72%) were asymptomatic throughout pregnancy. Major neonatal outcomes in our study were neonatal intensive care unit (NICU) hospitalization (20%), required neonatal resuscitation (14.55%), and neonatal mortality occurring in 1.82% cases. Gestational age at termination of pregnancy, when compared with different characteristics of fibroid, like type (p value 0.663), location (p value 0.552) and number of fibroid (p value 0.112), did not show any significant association. Similarly, maternal complications also did not show significant association (p value >0.05) with different characters of fibroid.  Conclusion: Pregnancies with fibroid are high-risk pregnancies that are linked to difficulties throughout the antepartum, intrapartum, and postpartum periods, as well as increased chances of cesarean delivery and PPH.

The use of sealing hemostat patch (HEMOPATCH®) in laparotomic myomectomy: a prospective case-control study

PURPOSE

Uterine myomas are the most common gynecological disease. In these cases, a myomectomy is performed traditionally laparotomically. However, alternatives have been widely used, including laparoscopic, endoscopic, and robotic surgery. During these techniques, diffuse parenchymatous bleeding remains one of the main intraoperative and postoperative complications and sometimes requires unplanned hysterectomies. Recently, hemostatic agents and sealants have been used to prevent excessive blood loss during surgical repair.

METHODS

We propose a prospective case-control study on the use of a sealing hemostat patch (HEMOPATCH^®) on uterine sutures in laparotomic myomectomy. In the period between July 2016 and April 2017, 46 patients with symptomatic uterine fibromatosis underwent surgery. They were divided into two groups of 23 patients, with different treatments in the hemostatic phase of oozing bleeding. HEMOPATCH^® is applied in group A, and spray electrocoagulation is applied in group B.

RESULTS

In group A, we achieve faster hemostasis (p < 0.05), than in group B. We report a significantly lower C-reactive protein value on the second and third days after surgery for group A compared to group B.

CONCLUSIONS

HEMOPATCH^®, during laparotomic myomectomy, is a valid alternative solution for obtaining rapid hemostasis and consequently intraoperative and postoperative bleeding. Furthermore, we suggest that a lower inflammatory peritoneal state is probably correlated with the barrier effect of the patch on the suture.

Clinical outcome analysis of intramural myoma greater than 8 cm in diameter removed during caesarean section: a retrospective study

OBJECTIVE

To explore the safety and efficiency of endometrial myomectomy (EM) and Serosal myomectomy (SM) for the removal of intramural myoma greater than 8 cm in diameter during cesarean section.

METHODS

Retrospective analysis and follow-up were used, and 190 cases of pregnancy complicated with uterine myoma from Jan. 2017 to May 2022 in Ningbo Women's and Children's Hospital were collected, 130 cases of caesarean myomectomy as study group, 64 cases of EM as study group A, 66 cases of SM as study group B, 33 cases with uterine fibroids removed before suturing the uterine incision as study group B1, 33 cases with uterine incision sutured followed by removal of fibroids as study group B2, 60 cases of Caesarean section alone as control group. To compare perioperative conditions between and within groups.

RESULTS

① Operation time, postoperative exhaust time, pre- and post-operative haemoglobin drop, intraoperative blood loss were all more than those of the control group in the study group (68.65 ± 11.87 vs 56.17 ± 9.18 min, 21.04 ± 4.98 vs 17.03 ± 1.3 h, 1.27 ± 0.59 vs 1.09 ± 0.43 g/dl, 613 ± 221 vs 532 ± 156 ml, P < 0.001, P < 0.001, P = 0.025, P = 0.011). ② For type III and V fibroids, the time of myoma removal, postoperative exhaust and pre- and post-operative haemoglobin drop and intraoperative blood loss in study group A were less than those in study group B (18.02 ± 3.89 vs 20.19 ± 5.32 min, 18.83 ± 2.57 vs 23.93 ± 6.84 h, 600 ± 194 vs 730 ± 277 ml, 1.20 ± 0.57 vs 1.59 ± 0.70 g/dl, P = 0.036, P < 0.001, P = 0.014, P = 0.008); For type IV uterine fibroids, only postoperative exhaust time was less in Study Group A than in Study Group B (19.27 ± 2.2 vs 21.35 ± 3.23 h, P = 0.016). ③ Time of myoma removed was less in study group B1 than in study group B2 (18.24 ± 4.53 vs 20.7 ± 4.59 min, P = 0.033).

CONCLUSION

It is safe and feasible to remove interstitial myomas larger than 8 cm in diameter during caesarean section. EM has the advantage of shorter operation time and less intraoperative bleeding, SM, in a way that the myoma is removed before suturing the uterine incision, can shorten the myomectomy time. It can benefit the patients more.

Risk factors based on myoma characteristics for predicting postoperative complications following cesarean myomectomy

OBJECTIVES

To evaluate the influence of myoma characteristics on cesarean myomectomy and to demonstrate its additional advantages.

METHODS

Retrospective data were collected from 292 women with myomas who had undergone cesarean section at Kangnam Sacred Heart Hospital between 2007 and 2019. We performed subgroup analysis according to the type, weight, number, and size of myomas. Preoperative and postoperative hemoglobin levels, operative time, estimated blood loss, length of hospital stay, incidence of transfusion, uterine artery embolization, ligation, hysterectomy, and postoperative complications were compared among subgroups.

RESULTS

There were 119 patients who had cesarean myomectomy and 173 who had cesarean section only. An increase in postoperative hospitalization and operation time was observed in the cesarean myomectomy group compared to that in the caesarean section only group (mean difference, 0.7 days, p = 0.01, 13.5 minutes, p <0.001). Estimated blood loss, hemoglobin differences, and transfusion rates were higher in the cesarean myomectomy than in the cesarean section only group. There were no differences in postoperative complications (fever, bladder injury, and ileus) between the two groups. No hysterectomy cases were reported in the cesarean myomectomy group. In subgroup analysis, the larger and heavier the myoma, the higher the risk of bleeding that led to transfusion. Estimated blood loss, differences in hemoglobin, and transfusion rate increased depending on myoma size and weight. A significant increase in postoperative hospitalization was observed in women with larger and heavier myomas. However, there was no statistical difference among the three types of myomas.

CONCLUSION

In cesarean myomectomy, larger (≥ 10 cm), and heavier myomas (≥ 500 g), were associated with postoperative outcomes, but not the number or type of myoma. The safety of cesarean myomectomy is not inferior to that of caesarean section only, considering its positive effects such as gynecological symptom relief and avoidance of the next surgery.

Comparison of surgical and obstetric outcomes in women with uterine leiomyomas after laparoscopic vs. abdominal myomectomy: A single-center cohort study

Our aim was to study the advantages, complications and obstetrical outcomes of laparoscopic myomectomy (LM) compared with abdominal myomectomy (AM). We conducted a retrospective cohort study at La Paz University Hospital that included LMs and AMs performed between 2012 and 2018, analyzing 254 myomectomies (142 AMs [55.7%] and 112 LMs [43.9%]). The mean number of fibroids was 1.8 ± 1.5 and 3 ± 2.9 for the LM and AM groups, respectively (p < 0.006). The mean size of the largest myoma was 7.6 cm ± 2.7 cm and 10.2 cm ± 5.4 cm for the LM and AM groups, respectively (p < 0.001). LMs were associated with longer surgical times (p < 0.001) and shorter hospitalizations (p = 0.001). There were no significant differences in the intraoperative and postoperative complication rates (p = 0.075 and p = 0.285 for LM and AM, respectively). The subsequent pregnancy rate was higher for the LM group (30.8% vs. 16.8%, p = 0.009), with a vaginal delivery rate of 69% and no cases of uterine rupture.

Clinical features at the time of non-hysteroscopic myomectomy before pregnancy, which affect adverse pregnancy outcomes: a retrospective cohort study

BACKGROUND

To investigate the association of clinical characteristics at the time of non-hysteroscopic myomectomy before pregnancy and adverse obstetric outcomes in the next pregnancy.

METHODS

In this retrospective cohort study, we identified 248 women who underwent abdominal or laparoscopic myomectomy for intramural (IM) and/or subserosal (SS) uterine myomas in Bundang CHA Medical Center before pregnancy and delivered at the same hospital between 2010 and 2020. The association between clinical characteristics at the time of myomectomy and subsequent obstetric outcomes was analyzed using the Chi-square test, the Student t-test or one-way ANOVA, and multivariable analysis.

RESULTS

There was one case of uterine rupture. The gestational age at delivery was 37.7 ± 2.4 weeks. There were 2 (0.8%) cases of fetal loss before 23 weeks, but there were no cases of perinatal death. The risk of transfusion during or after delivery was higher in the group in which multiple myomas were removed compared to the group in which only one was removed (aOR = 2.41, 95% CI [1.20-4.86], p = 0.014). The risk of neonatal composite morbidity was higher in the group in which myomas including the IM type were removed, than in the group in which only SS myomas were removed (aOR = 14.29, 95% CI [1.82-99.57], p = 0.012). Although not statistically significant, the group in which the sum of the diameters of the three largest myomas was greater than 15 cm showed a higher frequency of preterm birth (19.3% vs. 10.1%, p = 0.001) and lower birth weight (2901 ± 625 g vs. 3063 ± 576 g, p = 0.001) compared to the group with diameters less than 15 cm. Placenta accreta/increta (7.9% vs. 3.8%, p = 0.043) and lower placental weight (646 ± 170 g vs. 750 ± 232 g, p = 0.034) were more common in patients with an interval between myomectomy and pregnancy of less than 12 months compared to more than 12 months.

CONCLUSIONS

To our knowledge, this is the first study to investigate the association between clinical features at the time of myomectomy before pregnancy and various adverse obstetric and perinatal outcomes. If the removed myomas are multiple, IM, large, or the interval between myomectomy and pregnancy is short, the risk of obstetric and neonatal complications may increase.

Uterine myomas: effect of prior myomectomy on pregnancy outcomes

OBJECTIVE

Reproductive aged women with fibroids must weigh the risks and benefits of preconception myomectomy. Women with fibroids may have higher rates of fetal growth restriction (FGR) and stillbirth; however, there is a paucity of data on the impact of myomectomy on pregnancy outcomes. We compared perinatal outcomes in women with prior myomectomy versus those with no prior myomectomy and at least one fibroid ≥ 5 cm.

METHODS

Retrospective cohort study of women at a single center who delivered between 2008 and 2017 with a viable intrauterine pregnancy at initial ultrasound scan and either prior myomectomy, or, in the no-myomectomy cohort, at least one fibroid ≥ 5 cm on a prenatal scan performed at < 21 weeks' gestation (wga). Pregnancies complicated by major congenital anomalies were excluded. Primary outcome was preterm birth (PTB) < 37wga. Secondary outcomes included rates of spontaneous loss, cesarean delivery (CD), abnormal placentation, malpresentation, FGR, birthweight, birthweight percentile, estimated blood loss (EBL), blood transfusion, and neonatal survival to discharge.

RESULTS

A total of 290 women met inclusion criteria: 70 had a prior myomectomy, 220 women had ≥1 fibroid ≥5cm. Women with prior myomectomy were older, more likely to have private insurance, and more likely used artificial reproductive technology to conceive; 20% with prior myomectomy still had at least one ≥ 5 cm myoma on their obstetric scan. Rates of spontaneous loss were lower in the prior myomectomy group (1.4% vs 7.3%; p = .08). Of the 273 pregnancies continuing beyond 20 weeks, women with prior myomectomy had significantly more PTBs (35% vs. 21%, p = .02) and significantly different primary birth indications (p < .0001). However, after controlling for late preterm, prelabor cesareans recommended by providers in the myomectomy cohort, the difference in PTB rates was not significant (p = .13). The myomectomy group had more CDs (88% vs. 53%, p < .0001), higher EBL (1250 mL vs. 811 mL, p = .04), and a trend toward more blood transfusions (16% vs 8%, p = .05). Other selected outcomes were similar, including rates of FGR.

CONCLUSIONS

Women with prior myomectomy had significantly more PTBs, due in part to more preterm, prelabor cesareans in the late preterm period. Otherwise, prior myomectomy did not confer appreciable obstetric or perinatal benefits, as patients had more CDs, and higher EBL. Recommendations to perform preterm prelabor cesareans in this population may explain some of the PTB disparity. The effect of prior myomectomy on early pregnancy loss and infertility requires further study.

Importance of Fibrosis in the Pathogenesis of Uterine Leiomyoma and the Promising Anti-fibrotic Effects of Dipeptidyl Peptidase-4 and Fibroblast Activation Protein Inhibitors in the Treatment of Uterine Leiomyoma

Uterine fibroid or leiomyoma is the most common benign uterus tumor. The tumor is primarily composed of smooth muscle (fibroid) cells, myofibroblast, and a significant amount of extracellular matrix components. It mainly affects women of reproductive age. They are uncommon before menarche and usually disappear after menopause. The fibroids have excessive extracellular matrix components secreted by activated fibroblast cells (myofibroblast). Myofibroblast has the characteristics of fibroblast and smooth muscle cells. These cells possess contractile capability due to the expression of contractile proteins which are normally found only in muscle tissues. The rigid nature of the tumor is responsible for many side effects associated with uterine fibroids. The current drug treatment strategies are primarily hormone-driven and not anti-fibrotic. This paper emphasizes the fibrotic background of uterine fibroids and the mechanisms behind the deposition of excessive extracellular matrix components. The transforming growth factor-β, hippo, and focal adhesion kinase-mediated signaling pathways activate the fibroblast cells and deposit excessive extracellular matrix materials. We also exemplify how dipeptidyl peptidase-4 and fibroblast activation protein inhibitors could be beneficial in reducing the fibrotic process in leiomyoma. Dipeptidyl peptidase-4 and fibroblast activation protein inhibitors prevent the fibrotic process in organs such as the kidneys, lungs, liver, and heart. These inhibitors are proven to inhibit the signaling pathways mentioned above at various stages of their activation. Based on literature evidence, we constructed a narrative review on the mechanisms that support the beneficial effects of dipeptidyl peptidase-4 and fibroblast activation protein inhibitors for treating uterine fibroids.

Myomectomy during pregnancy; diagnostical dilemmas: two case reports and a systematic review of the literature

Myomectomy in pregnancy, until this day, remains very controversial. We present two cases of successful antepartum myomectomies performed in the second trimester of gestation. In both cases, the initial suspected origin of these tumours was the ovaries. However, as it was shortly after confirmed, since both women underwent laparotomy, the diagnosis of these masses was uterine fibroids. Both cases resulted on the live birth of two healthy infants via caesarean section. Secondarily, we conducted a thorough review of current data of myomectomies performed during pregnancy, including the characteristics and diagnosis of the myomas of pregnant women, the surgical details and complications, along with the outcomes of these gestations. Overall, the analysis of cases published in international literature, suggests that the surgical removal of myomas during pregnancy can be considered safe, given certain indications and considerations. Our review comprises of 71 women undergoing excision of fibroids during pregnancy. Only three cases ended in a miscarriage while the remaining 68 resulted in a second or third trimester delivery. However, the data concerning the safety of the procedure are scarce and originate mostly from case reports. Thus, conclusions on the exact maternal and obstetrical complication rates cannot be drawn.

Early identification of uterine scar defect by preconception magnetic resonance imaging to achieve successful pregnancy outcome after laparoscopic-assisted myomectomy: Two case reports

Myomectomy improves the reproductive ability of women. However, the risk for uterine rupture and abnormal placentation remains a concern. In two cases with scar defects after laparoscopic-assisted myomectomy, one case developed amniocele, while other case showed abnormally invasive placenta. Obstetrical management measures with cesarean sections yielded uneventful postoperative courses.

Pregnancy outcomes and associated factors for uterine rupture: an 8 years population-based retrospective study

Background

Uterine rupture is an obstetrical emergency with serious undesired complications for laboring mothers resulting in fatal maternal and neonatal outcomes. The aim of this study was to assess the incidence of uterine rupture, its association with previous uterine surgery and vaginal birth after caesarean section (VBAC), and the maternal and perinatal implications.

Methods

This is a population-based retrospective study. All pregnant women treated for ruptured uterus in one center between 2013 and 2020 were included. Their information retrieved from the medical records department were reviewed retrospectively.

Results

A total of 209,112 deliveries were included and 41 cases of uterine rupture were identified. The incidence of uterine rupture was 1.96/10000 births. Among the 41 cases, 16 (39.0%) had maternal and fetal complications. There were no maternal deaths secondary to uterine rupture, while perinatal fatality related to uterine rupture was 7.3%. Among all cases, 38 (92.7%) were scarred uterus and 3 (7.3%) were unscarred uterus. The most common cause of uterine rupture was previous cesarean section, while cases with a history of laparoscopic myomectomy were more likely to have serious adverse outcomes, such as fetal death. 24 (59.0%) of the ruptures occurred in anterior lower uterine segment. Changes in Fetal heart rate monitoring were the most reliable signs for rupture.

Conclusions

Incidence of uterine rupture in the study area, Shanghai, China was consistent with developed countries. Further improvements in obstetric care and enhanced collaboration with referring health facilities were needed to ensure maternal and perinatal safety.

Surgical Treatment of "Large Uterine Masses" in Pregnancy: A Single-Center Experience

Uterine myomas or uterine fibroids are the most common benign uterine masses affecting women. The management of large myoma during pregnancy is challenging, and surgical treatment is a possible option. We report nine cases of pregnant women affected by uterine masses larger than 10 cm, who underwent surgical treatment during the second trimester of pregnancy. In all cases, the masses were preconceptionally unknown and diagnosed during the first trimester. In eight cases, no maternal and fetal complications arose during or after surgical treatment and delivery occurred at full term of pregnancy. In one case, spontaneous abortion was recorded. In all cases, histologic diagnosis demonstrated the benign nature. Women affected by large uterine masses diagnosed for the first time in pregnancy could be taken into consideration for surgical treatment in a referral center during the second trimester.

Central Placenta Previa With Coexisting Central Cervical Fibroid in Pregnancy: An Obstetrician's Nightmare

Pregnancy with central placenta praevia and a coexistent cervical fibroid is infrequently encountered in clinical practice. A patient with this unusual combination is a nightmare for any clinician, especially if she presents with obstetric emergencies. In this scenario, there is a high chance of catastrophic obstetric hemorrhage during the peripartum period leading to a fatal outcome. We report a case of a 27-year-old lady at term pregnancy, who was brought to emergency in labor pain with antepartum hemorrhage. Subsequently, she was diagnosed to have central placenta praevia along with a large central cervical fibroid. An emergency cesarean section was performed to deliver the child. Intraoperatively, she had a major postpartum hemorrhage which was successfully managed with intrauterine balloon tamponade, hemostatic sutures, and uterine artery ligation. We could avoid cesarean hysterectomy by precise anticipation, meticulous planning, and step-wise protocol-driven management.

Is an abdominal cerclage indicated with a cervical myomectomy? A case report

INTRODUCTION

Cervical myomectomy can compromise cervical integrity and the risk of subsequent cervical incompetence is unclear. In this case report, the literature on cervical myomectomies is reviewed as well as that on the potential benefits of cervical cerclage.

CASE PRESENTATION

A 30-year-old woman, nulligravida, with a 12 cm cervical leiomyoma consulted for heavy menstrual bleeding and pelvic pain. After failure of multiple medical therapies, a laparoscopic cervical myomectomy was successfully performed after pre-operative uterine artery embolization using absorbable gelatin sponges to reduce surgical blood loss.

DISCUSSION

A concomitant laparoscopic cerclage was achieved in order to prevent cervical incompetence, given that the full thickness of the anterior cervix was penetrated during the myomectomy.

Systematic review of reproductive outcomes after High Intensity Focused Ultrasound treatment of uterine fibroids

PURPOSE

Myomectomy is currently the gold standard for the treatment of uterine fibroids in women who desire pregnancy. However, this surgical fibroid removal has a long convalescence. Promising alternatives may be non-invasive High Intensity Focused Ultrasound (HIFU) under either MRI (MR-HIFU) or ultrasound guidance (USgHIFU). In this systematic review, an overview is provided of reproductive outcomes after these two relatively new ablation techniques.

METHOD

A systematic literature search was performed to identify studies reporting reproductive outcomes after HIFU treatment of fibroids. Only peer reviewed, full papers were included. Outcomes included pregnancy-, live-birth- miscarriage and caesarian section rate, time to conceive, reported complications, and possible prognostic factors.

RESULTS

In total 21 studies were included. Fourteen studies reported 124 pregnancies after MR-HIFU. Two placenta previas and no uterus ruptures were reported. Pregnancy rates were only retrospectively collected and ranged between 7% and 36%. Miscarriage rate in the oldest and largest prospective registry was 39%. After USgHIFU 366 pregnancies were reported with one fetal intrauterine death, six placenta previas and no uterus ruptures. The only prospective study reported a pregnancy rate of 47% and a miscarriage rate of 11%. Possible prognostic factors like age were not available in most studies.

CONCLUSIONS

Based on the heterogeneous data currently available, reproductive outcomes after HIFU appear non-inferior to outcomes after the current standard of care. However, a (randomized) controlled trial comparing reproductive outcomes after HIFU and standard care is necessary to provide sufficient evidence on the preferred fibroid treatment for women with a pregnancy wish.

Myomectomy during pregnancy: an obstetric overview and two case-series

INTRODUCTION

Uterine fibroids (UFs) are the most common benign disease affecting female reproductive system, occur in 20-40 % of women, and in 10 % of pregnancies. The aim of the investigation was to summarize evidences about the management and treatment of UFs and related complications in pregnancy.

MATERIALS AND METHODS

A literature review was performed using scientific databases, including all case report and case series, using a combination of key words relating to the problem exposed. Data about gestational age at diagnosis, maximum fibroids diameter, type of surgery and gestational age at surgery, delivery and perinatal outcome were collected. Two clinical cases were also included.

RESULTS

Sixty-six articles were selected and 199 patients were included. In 76 % of patients the gestational age at myomectomy was lower than 20 weeks, in 85 % laparotomic surgery was chosen, in 41 % of cases the maximum fibroid diameter was between 7-20 cm, in 41 % of pregnancies the route of delivery was cesarean section. The eight percent of cases was complicated by miscarriage or fetal demise or neonatal death.

CONCLUSIONS

Myomectomy is a feasible procedure in those pregnancies complicated by symptomatic fibroids, though surgery in pregnancy is associated with an increased risk of obstetric complications.

Use of point-of-care ultrasound to diagnose spontaneous rupture of fibroid in pregnancy

Background: Complications of fibroids in pregnancy are well known, including postpartum hemorrhage, labor dystocia, and cesarean delivery. Outside of pregnancy and labor, the rare occurrence of spontaneous fibroid rupture has been documented. Case: The current case report involves a woman who presented with acute abdominal pain in the third trimester of pregnancy and was found to have spontaneous rupture of a fibroid before the onset of labor. Her initial presentation, diagnosis through use of point-of-care ultrasound, acute surgical management, and postoperative course are described. Conclusion: When assessing acute abdominal pain in a pregnant patient, fibroid rupture should be considered despite the absence of prior uterine surgery. Bedside point-of-care ultrasonography is a useful tool for assessment of abdominal pain in the third trimester of pregnancy.

Large Uterine Fibroids in Pregnancy with Successful Caesarean Myomectomy

Uterine fibroid is the commonest benign tumour of the female reproductive tract. It occurs in 20–40% of women, whereas the estimated incidence in pregnancy is 0.1–3.9%. Uterine fibroid in pregnancy is usually asymptomatic with complications occurring in 10–30% of cases. The first line of management is conservative with counselling for myomectomy after delivery. However, in the presence of intractable symptoms, both antepartum myomectomy and caesarean myomectomy have been reported to be successfully performed in carefully selected cases. We report a case of large subserous uterine fibroid in pregnancy that was referred to our centre at 14 weeks of gestation. She developed generalized body weakness, backache, and breathlessness at 27 weeks gestation. Thus, she was admitted and managed conservatively for eight weeks with significant relief of symptoms. She eventually had a caesarean myomectomy at 35 weeks of gestation; the outcome was a live female baby with a birth weight of 2.3 kg and a large subserous fibroid weighing 9.5 kg. We can therefore say that caesarean myomectomy can be safely performed in carefully selected cases.

Nationwide population-based cohort study of adverse obstetric outcomes in pregnancies with myoma or following myomectomy: retrospective cohort study

BACKGROUND

Our objective was to evaluate risks of adverse obstetric outcomes in pregnancies with myoma(s) or in pregnancies following myomectomy.

METHODS

We analyzed the national health insurance database, which covers almost the entire Korean population, between 2004 and 2015. The risks of adverse pregnancy outcomes in pregnancies with myoma(s) or in pregnancies following myomectomy, compared to those in women without a diagnosed myoma, were analyzed in multivariate logistic regression analysis.

RESULTS

During the study period, 38,402 women with diagnosed myoma(s), 9890 women with a history of myomectomy, and 740,675 women without a diagnosed myoma gave birth. Women with a history of diagnosed myoma(s) and women with a history of myomectomy had significantly higher risks of cesarean section (aOR 1.13, 95% CI 1.1-1.16 and aOR 7.46, 95% CI 6.97-7.98, respectively) and placenta previa (aOR 1.41, 95% CI 1.29-1.54 and aOR 1.58, 95% CI 1.35-1.83, respectively), compared to women without a diagnosed myoma. And the risk of uterine rupture was significantly higher in women with previous myomectomy (aOR 12.78, 95% CI 6.5-25.13), compared to women without a diagnosed myoma, which was much increased (aOR 41.35, 95% CI 16.18-105.69) in nulliparous women. The incidence of uterine rupture was the highest at delivery within one year after myomectomy and decreased over time after myomectomy.

CONCLUSIONS

Women with a history of myomectomy had significantly higher risks of cesarean section and placenta previa compared to women without a diagnosed myoma.

Cesarean myomectomy in the last ten years; A true shift from contraindication to indication: A systematic review and meta-analysis

BACKGROUND

A lot of debate is present about Cesarean myomectomy (CM) in women with uterine myoma whether to consider it a feasible and safe procedure or an absolute contraindication.

OBJECTIVE

To assess the safety and feasibility of myomectomy during cesarean section in women with uterine myoma.

SEARCH STRATEGY

Electronic search was made on MEDLINE, EMBASE, Cochrane Library, ISI web of knowledge and Scopus from January 1, 2008 to December 31, 2019 using terms "Caesarean section", "Myomectomy", "Fibroid", "Caesarean myomectomy".

SELECTION CRITERIA

All full length studies either prospective or retrospective that address caesarean myomectomy were included.

DATA COLLECTION AND ANALYSIS

The outcomes studied were haemorrhage, mean change in haemoglobin, operative time, need for blood transfusion, febrile morbidity and duration of hospital stay.

RESULTS

Total 249 studies were assessed for eligibility and 17 studies included in analysis with 6545 women. There were 4702 (71.85 %) women in caesarean myomectomy (CM) group and 1843 (28.15 %) women in cesarean section (CS) group. There was statistically significant but clinically insignificant decrease in hemoglobin [MD = 0.27, 95 %CI = 0.08-0.45, p = 0.005; very low quality], significant higher need for blood transfusion [RR = 1.45, 95 %CI = 1.05-1.99, p = 0.02; high quality] in CM group versus CS alone. The mean operative time (minutes) [MD = 14.77, 95 %CI = 6.91-22.64, p = 0.0002; moderate quality] and mean hospital stay (days) [MD = 0.36, 95 %CI = 0.19-0.53, p < 0.00001; high quality] was significantly less in CM group, though of not any clinical significance. No difference in incidence of haemorrhage [RR = 1.16, 95 %CI = 0.86-1.56, p = 0.32; moderate quality evidence] and fever [RR = 1.17, 95 %CI = 0.83-1.65), p = 0.36; moderate quality] in two groups.

CONCLUSIONS

The meta-analysis suggests CM is associated with clinical insignificant increase in operative time, blood loss and hospital stay, especially with multiple and large size myomas. CM should be preferred over CS alone especially by experienced surgeons with appropriate haemostatic techniques and tertiary care centres.

Management of pregnancy in case of multiple and giant uterine fibroids

Uterine fibroids are common among women of reproductive age. During the pregnancy, the potential complications of fibroids, although rare, are of frequent clinical concern. Available studies describing management and obstetrical outcomes in pregnant women with giant fibroids are limited. We present the case of a 39-year-old pregnant woman with multiple and large uterine fibroids. During the pregnancy, there was adequate fetal development, without major maternal complications. Given the characteristics of the fibroids and breech position of the fetus, an elective caesarean section was decided, and postpartum hysterectomy planned. This challenging obstetrical case required a multidisciplinary approach.We considered crucial discussing five main issues: preconceptional counselling, tailored pregnancy surveillance, decision of time and route of delivery, decision to perform a peripartum hysterectomy and management of decreasing blood loss perioperatively. Given the limitation of the published reports, we believe that sharing our experience, along with a literature review, is beneficial for other clinicians.

Management in cases of large uterine myomas in pregnancy

Objectives

Uterine fibroids are the most common benign tumors in women of procreative age. The effects of their occurrence affect the course of pregnancy by increasing the frequency of abortions, premature delivery or premature abruption of the placenta. Medical treatment includes clinical observation, pharmacological pain control, myomectomy during pregnancy or perinatal hysterectomy.

Case presentation

We present a survey of literature and the case of a pregnant woman with an enormous uterine fibroid 23×13×16 cm on the basis of which a diagnostic-therapeutic scheme for tumors of the reproductive organs during pregnancy has been developed.

Conclusions

The study presents improved recommendations for management the pregnancies in presence of the uterine myomas based on clinical practice.

Myomectomy during pregnancy: A systematic review

OBJECTIVE

Uterine fibroids affect 2-10 % of pregnant women. Although usually asymptomatic, they may be associated with pregnancy complications. Myomectomy is preferably avoided antenatally, however, it has been reported in symptomatic cases that did not respond to conservative management. The aim of this study was to summarize the published literature and present the reported outcomes and associated risks of this procedure.

STUDY DESIGN

A systematic research of the literature was conducted in PubMed/MEDLINE, Scopus and the Cochrane Library, including case reports and case series. An effort was made to numerically analyse all parameters included in the case reports.

RESULTS

Overall, 54 relevant articles were identified, including 97 patients. The median gestational age at diagnosis was 13 (range 6-26) weeks, while the median age at myomectomy was 16 (range 6-26) weeks. Abdominal pain, not responding to medical treatment was the most common indication for surgery. The median number of fibroids removed per patient was one (range 1-5). Most of them were subserous pedunculated or subserous and fundal. Laparotomy (78.4 %) was the principal surgical approach, however, laparoscopic and vaginal operations were also reported. The median duration of surgery was 53 (range 20-150) min. The histopathology revealed necrosis and degeneration as the main findings of removed fibroids. The pregnancy outcome was favourable in most of the cases, with few complications reported.

CONCLUSION

Based on the limited published data, myomectomy during pregnancy appears as a safe procedure in cases of symptomatic uterine fibroids not responding to conservative management and therefore it may be considered, following appropriate counselling regarding the associated risks.

Uterine Myomas: Focused Ultrasound Surgery

Uterine fibroids are the most common neoplasm in women. These lesions may be associated with impaired fertility and adverse obstetric outcomes. Medical treatment, myomectomy, hysterectomy and uterine artery embolization have been employed for the management of uterine fibroids. Focused ultrasound surgery (FUS) is a relatively recent technique that relies on mechanical and thermal energy of ultrasound for the ablation of a target tissue under an imaging guidance, that can be either ultrasound (US-guided FUS, USgFUS) or magnetic resonance (MR-guided FUS, MRgFUS). Pre- and peri-menopausal women are potential candidates for treatment; however, individual criteria need to be evaluated in order to establish the eligibility for the procedure. FUS procedure can be performed in an outpatient setting; it is a safe and effective treatment that has demonstrated to reduce symptoms associated with uterine fibroids. The adverse event rate is 8.7% and only 0.2% of patients experiences major complications. Pregnancy is possible after the treatment, and no damage to the endometrium has been observed following FUS procedure.

Obstetrical outcomes are unchanged after hysteroscopic myomectomy in women with submucosal fibroids

BACKGROUND

Previous studies have demonstrated increased rates of poor obstetrical outcomes including preterm delivery, placental abruption, and intrauterine growth restriction in women with uterine leiomyomas. Currently, preconception myomectomy has not been reported to improve pregnancy rates or pregnancy outcomes in women with subserosal leiomyomas, and the data remain inconclusive for intramural fibroids. Pregnancy rates have been found to improve after the removal of submucosal fibroids. However, the effect of preconception myomectomy for submucosal fibroids on birth outcomes has yet to be examined.

OBJECTIVE

This study aimed to determine whether hysteroscopic excision of submucosal leiomyomas affects the rate of preterm delivery, among other obstetrical outcomes.

STUDY DESIGN

We performed a retrospective case-control study of women who underwent hysteroscopic resection of leiomyomas (cases) and controls of women who had submucosal fibroids at the time of their first-trimester ultrasounds. Women were included if they delivered a nonanomalous fetus beyond 20 weeks' gestation. A total of 73 cases were identified and matched with 219 controls (case-to-control ratio, 1:3). Subsequently, owing to multiple-gestation pregnancy, 11 patients were excluded from the case population and 4 patients from the control group. The final analysis included 277 women-62 cases and 215 controls. Our primary outcome was preterm delivery before 37 weeks' gestation. Prespecified secondary outcomes of interest were preterm delivery before 34 weeks' gestation, placental abruption, fetal malpresentation, intrauterine growth restriction, and rate of cesarean delivery. Data analysis was performed using univariate and multivariate statistics.

RESULTS

Cases and controls were similar with respect to age, race, body mass index, and mode of delivery. Cases were more likely to be primiparous (66% cases [42 of 62] vs 37% controls [80 of 215]; P=.00) and use assisted reproductive technology to conceive (22.6% cases [14 of 62] vs 7.0% controls [15 of 215]; P<.001). No differences were found in the rate of preterm delivery at <37 weeks' gestation (12.9% cases [8 of 62] vs 13.5% controls [29 of 215]; P=.89), preterm delivery at <34 weeks' gestation (4.84% cases [3 of 62] vs 6.97% controls [15 of 215]; P=.77), or other obstetrical outcomes.

CONCLUSION

Overall, women with submucosal uterine leiomyomas who undergo hysteroscopic removal have similar birth outcomes to those who do not.

The Association between Placenta Implantation at Prior Myomectomy Locations and Perinatal Outcomes in Pregnant Women Who Previously Underwent One-Step Hysteroscopic Myomectomy

Objectives:

There are no data describing the correlation between placenta implantation at prior myomectomy locations and perinatal outcomes in pregnant women after transcervical resection myomectomy (TCR-M). The aim of the study is to investigate the correlations between placenta implantation at prior myomectomy locations and perinatal outcomes in pregnant women who had previously undergone TCR-M.

Materials and Methods:

This was a retrospective, single-center study. We reviewed the records of 34 pregnant women who had previously undergone TCR-M for submucosal myoma and perinatal care in our hospital between January 2012 and January 2019. We examined surgical and pregnancy outcomes and evaluated correlations between placenta implantation at prior myomectomy locations and perinatal outcomes in women who delivered after 22 gestational weeks (n = 24).

Results:

Median maternal age at conception was 38 years (range, 28–44) and median duration between TCR-M and conception was 1.4 years (range, 0.3–5.8). There were 24 deliveries after 22 gestational weeks and 10 pregnancy losses. Among these 24 deliveries, the median gestational age at delivery was 39 weeks (range, 34–41); median birthweight, 3025 g (range, 2092–4012); and median blood loss at delivery, 573 g (range, 100–3000). There were no cases of placenta accreta and uterine rupture. Placenta implantation at a prior myomectomy location was detected in 14/24 women using transabdominal ultrasonography. Median blood loss was significantly higher in the implantation than in the nonimplantation group (P < 0.01).

Conclusion:

Our one-step TCR-M is useful for women with submucosal myoma. However, we suggest that clinicians should review and check the association between prior myomectomy locations and placenta implantation.

A Rare Case of Pregnancy Complicated by Uterine Prolapse and Cervical Fibroid

Uterine prolapse and cervical fibroid are two common gynecological conditions but relatively uncommon in pregnant women. However, these conditions can complicate normal pregnancy by significantly altering its course and outcome. Obstetricians should, therefore, familiarize themselves with the presentations, challenges, and outcomes of these unique situations to effectively manage the patient in the perinatal period. We report a rare case, where both uterine prolapse and cervical fibroid coexisted in a single pregnancy.

Anxiety of myoma patients: results of standardized interviews with the State Trait Anxiety Inventory and the Kessler 10 questionnaire

Introduction: The aim of this study was to explore a possible relation between myoma-related anxieties and general state or trait anxiety or psychological distress, to get a better understanding of the impact of anxiety on the patients.Methods: This prospective study was conducted at the myoma clinic of a large university hospital in a major European city from November 2016 to February 2017. Patients completed standardized questionnaires on myoma-related fears, the State Trait Anxiety Inventory (STAI), and the Kessler 10.Results: Eighty-five out of 88 women agreed to participate. State-anxiety on the STAI had a mean of 49.4 (11 points above the norm (p < .001)), and trait-anxiety had a mean of 42.0 (5 points above the norm (p = .001)). Thirty-seven percent of the patients had distress values on the K10 above the norm (defined as <20). More myoma-related fears correlated with higher scores on the Kessler and STAI. The scores were not related to the level of information about myomas or duration of illness.Conclusions: Myoma-related fears correlated with higher mental distress and elevated state and trait anxiety levels. Thus, physicians can contribute to the overall well-being of patients when they relieve them of the myoma-related anxiety. Further research is needed to determine whether treatment has any impact on anxiety or mental distress.

Prognostic Value of Doppler Ultrasound in Triplets Conceived by In Vitro Fertilization: A Case Report and Review of the Literature

Umbilical artery Doppler ultrasound-which informs on maternal-fetal-placental blood flow-may be the most valuable surveillance tool in triplet pregnancies, crucial to diagnose early fetal growth restriction. To illustrate the prognostic value of Doppler ultrasound and launch a discussion of its role in multiple gestational, high-risk pregnancy, we present the case of a 42-year-old woman with trichorionic triamniotic triplet pregnancy conceived by in vitro fertilization, who showed early signs of poor outcome for one of the triplets via umbilical artery Doppler by the 23rd week and middle cerebral artery Doppler by the 29th week of gestation.

The role of magnetic resonance-guided focused ultrasound in fertility-sparing treatment of uterine fibroids-current perspectives

Uterine fibroids (UFs) are the most common benign tumours of the female reproductive system and the most frequent reason for hysterectomy worldwide. UFs are reported in 20%–70% of women of reproductive age depending on a study group. Although most women with UFs are asymptomatic, over 30% of them will present with different symptoms. Abnormal uterine bleeding, pain, pressure and infertility are the most common. Lesions that cause these kinds of symptoms may require medical intervention.

Trends in UF treatment change along with patient awareness and the introduction of new methods and techniques. Selecting an appropriate treatment option should be individualised and adjusted to the patient’s expectations as much as possible. This choice will mostly depend on the patient’s age, UF location, the size and number of lesions, severity of symptoms and, most importantly, the patient’s expectations concerning the preservation of fertility. Observations made for the past few years showed an increasing number of pre- and perimenopausal women who wish to preserve their uterus or decline surgery. In line with current trends and demands in medicine, great importance is attached to the development and upgrade of new minimally invasive or noninvasive procedures in UF therapy.

Magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU) is not associated with severe destruction of the uterine cavity and walls. For this reason, this method may be considered as a kind of hope in fertility-sparing UF therapy and the data about its use in this indication raises future hope. In this review, we summarise the available data on the use of MR-HIFU as a fertility-sparing method in the treatment of UFs. We also indicate how it could evolve in the future.

According to the available data, MR-HIFU is a relatively safe noninvasive method which seems not to deteriorate fertility compared to the pre-treatment status. MR-HIFU may constitute an alternative solution and be chosen in patients who meet the qualification criteria and deny other methods, which also facilitates the use of other treatment options in case the procedure is ineffective. Further randomised studies are necessary to confirm the above information.

Relationship between a uterine fibroid diagnosis and the risk of adverse obstetrical outcomes: a cohort study

OBJECTIVE

The aim was to investigate the association between clinically significant uterine fibroids and preterm birth, caesarean section (CS), postpartum haemorrhage (PPH), placental abruption, intrauterine growth restriction (IUGR) and uterine rupture.

METHODS, PARTICIPANTS AND SETTING

A historical cohort study based on data from the Danish National Birth Cohort, the Danish National Patient Registry and the Danish National Birth Registry (DNBR). The final study population consisted of 92 696 pregnancies and was divided into four groups for comparison. Group 1: pregnancies of women without a fibroid diagnosis code or fibroid operation code; group 2: pregnancies of women with a fibroid diagnosis code before pregnancy, during pregnancy or up to 1 year after delivery, and no fibroid operation code before pregnancy; group 3: pregnancies of women with a fibroid diagnosis code given more than 1 year after delivery; and group 4: pregnancies of women with a fibroid operation code given before pregnancy.

RESULTS

A diagnosis of fibroids before pregnancy yielded an increased risk of preterm birth (gestational age (GA) ≤37 weeks) (OR 2.27 (1.30─3.96)) and extreme preterm birth (GA 22+0─27+6 weeks, OR 20.09 (8.04─50.22)). The risk of CS was increased (OR 1.83 (1.23─2.72)) for women with a fibroid diagnosis code given before pregnancy; significantly increased risk of elective CS (OR 1.92 (1.11─3.32)), but not acute CS (OR 1.54 (0.94─2.52)). The risks of PPH, placental abruption or IUGR were not increased in any of the groups.

CONCLUSION

We found a strong association between clinically significant uterine fibroids and preterm birth, and an association between clinically significant uterine fibroids and CS. In contrast, no association between clinically significant uterine fibroids and PPH, placental abruption or IUGR was seen.

The Significant Risk Factors of Intra-Operative Hemorrhage during Laparoscopic Myomectomy: A Systematic Review

Laparoscopic myomectomy (LM) is becoming increasingly common in the management of uterine myomas and is usually offered regardless of the number, location, and size of the myomas. It has a generally low rate of periprocedural complications and is preferred to laparotomy for several reasons that are not limited to decreased length of hospital stay, number of sutures, smaller incisions, and decreased pain. However, blood loss during LM remains a challenge. To be able to stratify patients and provide better management after LM, it is crucial to identify these predictors of blood loss. Therefore, the aim of this review was to identify the risk factors for periprocedural blood loss after laparoscopic uterine myomectomy. According to our data synthesis, age, body mass index, and phase of the menstrual cycle do not seem to affect the blood loss during LM. Conversely, size and number of myomas, as well as operative time, was directly related to the increase of blood loss.

Vaginal delivery after laparotomic myomectomy during pregnancy

Background

Symptomatic myomas during pregnancy are a rare condition that could however turn into an emergency because of torsion, necrosis, growth and compression leading to acute abdomen, potentially threating for pregnancy. Surgeons are usually reluctant to perform myomectomy during pregnancy because of an increased uterine blood flow and volume can give rise to a potential risk for haemorrhagic complications, while uterine manipulation can determine adverse pregnancy outcome. However, in some rare cases surgery is compulsory.

Case presentation

Here, we described a case of a successful laparotomic myomectomy performed during pregnancy at 11 weeks of gestation when an acute abdomen occurred. Surgery was followed by regular obstetrics follow-up ended with a spontaneous vaginal delivery with no pregnancy complications.

Conclusion

Although few case reports are described in literature, other authors have performed a myomectomy during pregnancy, and fewer cases have had a subsequent vaginal delivery, so that nowadays there is no clinical evidence on which to base best practice. This case shows that vaginal delivery after a laparotomic myomectomy performed during pregnancy, in selected cases, can be considered as a feasible option.
