Effects of Laparoscopic Versus Minilaparotomic Myomectomy on Uterine Leiomyoma: A Meta-analysis

Clinical comparison of laparoscopic and open surgical approaches for uterus-preserving myomectomy: a retrospective analysis on patient-reported outcome, postoperative morbidity and pregnancy outcomes

PURPOSE

Uterine fibroids pose clinical challenges due to varied symptoms and impact on fertility. Aim of this research is to compare open and laparoscopic myomectomy, with focus on evaluating their effects on patients' quality of life and analyzing their implications for pregnancy outcomes.

METHODS

This retrospective study compares open and laparoscopic myomectomy outcomes in 168 patients treated October 2017 and July 2023. Preoperative characteristics and postoperative outcomes in terms of symptoms and pregnancy outcomes were examined.

RESULTS

The patient cohort comprised patients with a high symptom burden. Only 51.2% expressing a desire for future pregnancies, highlighting diverse motivations for uterus-preservation. No significant differences were observed in preoperative symptoms. Larger and multiple myomas were associated with a higher likelihood of laparotomy. Recurrence rates were lower after laparoscopy (10.2% vs. 23.8%, p = 0.02). Cesarean section recommendations were more frequent post-laparotomy group (36.6% vs. 86.6%, p = 0.000). Morbidities and satisfaction showed no significant differences between approaches, with slightly better bleeding improvement after laparotomy. Despite similar pregnancy outcomes, a high proportion of patients did not conceive postoperatively (75.4%). Among patients who became pregnant postoperatively (n = 31), most patients conceived after one year or more, with no dependence on the surgical approach (p = 0.227).

CONCLUSION

Both open and laparoscopic myomectomy surgeries showed high patient satisfaction, symptom alleviation, and comparable pregnancy results. A preference emerged for laparoscopy in terms of cesarean section recommendations and recurrence risk. Laparoscopic procedures tended to offer higher operative satisfaction and fewer complications. The study emphasized the complexity of therapeutic decision-making.

Comparison of uterine myometrial thickness at the site of myomectomy scar after surgery using laparoscopic and laparotomy methods

Fibroids are the most common benign tumours of the uterus, often requiring surgery when symptomatic. This study aims to investigate the impact of surgery using two methods, laparoscopy and laparotomy, on the thickness and vascularity of the uterine myometrium at the site of myomectomy scar (comparing sonographic features at the surgical scar site, including thickness, vascularity, and the extent of fibrotic tissue, in both open and laparoscopic surgical approaches). In this clinical trial, 100 women with type 2-5 fibroids and clinical symptoms, seeking surgery et al. Zahra Hospital, were enrolled in two groups: laparoscopy and laparotomy. Inclusion criteria were a maximum fibroid size of 8 cm and, in the case of multiple fibroids, a maximum of three, with the largest being 8 cm. 6 months post-surgery, sonographic assessments of the myomectomy scar site were compared between both groups. Participants showed no significant differences in demographic and obstetric factors. The most common clinical symptom (87%) in both groups was abnormal uterine bleeding (AUB). The mean hospital stay duration was statistically significantly lower in the laparoscopy group at 1.64 (SD 0.56) compared to 1.89 (SD 0.58) in the laparotomy group (p = 0.028). Additionally, the decrease in haemoglobin levels was 0.89 (SD 0.92) and 1.87 (SD 2.24) units, respectively, which showed a statistically significant difference (p = 0.003). The duration of surgery was significantly shorter in the laparotomy group (p = 0.001). Abdominal pressure was not observed in the laparoscopy group, while 12% of the laparotomy group reported complaints (p = 0.013). Based on the results obtained in this study, it can be concluded that there was no difference between these two methods in terms of improving uterine thickness and associated complications. However, the decrease in haemoglobin levels and the length of hospital stay were lower in patients undergoing laparoscopy.

Analysis of Pregnancy Outcomes after Laparoscopic Myomectomy: A Retrospective Cohort Study

Objective. This study aimed to investigate the factors related to pregnancy outcomes after laparoscopic myomectomy. Methods. A retrospective review was conducted on 156 patients aged 18 to 45 years who underwent laparoscopic myomectomy in Ningbo Women and Children’s Hospital from January 2010 to December 2016. Follow-up medical records and information were collected on demographic variables, clinical variables, and postoperative pregnancy rate. The logistic regression model was used to assess the association between related factors and postoperative pregnancy rate or pregnancy outcome. The outcome indicators included $\text{abortion}=0$ , $\text{premature}\text{birth}=1$ , and $\text{full}\text{term}=2$ . The chi-squared test or Fisher’s exact test was used to compare the differences in pregnancy outcomes, postpartum hemorrhage, and placenta adhesion between the cohorts. Results. The size of fibroids correlated with the postoperative pregnancy rate. The larger the fibroids, the lower the postoperative pregnancy rate, and the difference was statistically significant. The number of fibroids and placental adhesions was positively associated with postoperative pregnancy; the higher the number of fibroids, the higher the incidence of placental adhesions. However, the postoperative interval of pregnancy, fibroid size, and number and type of fibroids are not correlated with the pregnancy outcomes of postoperative patients. Conclusions. The size of myoma may influence the pregnancy rate of patients after laparoscopic myomectomy. The number of fibroids can affect the incidence of placental adhesions during postoperative pregnancy.

Thromboangiitis obliterans plasma-derived exosomal miR-223-5p inhibits cell viability and promotes cell apoptosis of human vascular smooth muscle cells by targeting VCAM1

Background: Exosomes-encapsulated microRNAs (miRNAs) have been established to be implicated in the pathogenesis of different diseases. Nevertheless, circulating exosomal miRNAs of thromboangiitis obliterans (TAO) remains poorly understood. This study aimed to explore the effects of exosomal miRNAs associated with TAO on human vascular smooth muscle cells (HVSMCs).Methods: The exosomes were isolated from the plasma of TAO patients and normal controls and then were sent for small RNA sequencing. Differentially expressed miRNAs (DE-miRNAs) were identified by bioinformatics analysis and were confirmed by RT-qPCR. After that, PKH67 staining was used to label exosomes and co-cultured with HVSMCs. Cell viability and apoptosis were, respectively, tested by CCK-8 assay and flow cytometry. Finally, dual-luciferase reporter assay was used to confirm the downstream targets of miR-223-5p.Results: A total of 39 DE-miRNAs were identified between TAO patients and normal controls, of which, miR-223-5p was one of the most significantly up-regulated miRNAs. TAO plasma-derived exosomes or miR-223-5p mimics inhibited cell viability of HVSMCs and promoted cell apoptosis. The pro-apoptotic effect of TAO plasma-derived exosomes was alleviated by miR-223-5p inhibitor. Additionally, the expressions of VCAM1 and IGF1R were down-regulated by exosomes and miR-223-5p mimics, and were abrogated by miR-223-5p inhibitor. Dual-luciferase report showed that VCAM1 was the target of miR-223-5p.Conclusions: Our findings imply that circulating exosomal miR-223-5p may play an essential role in the pathogenesis of TAO, and provide a basis for miR-6515-5p/VCAM1 as novel therapeutic targets and pathways for TAO treatment.

Comparison of safety and efficacy between laparoscopic myomectomy and traditional laparotomy for patients with uterine fibroids and their effect on pregnancy rate after surgery

The aim of this retrospective study was to compare the safety and efficacy between laparoscopic myomectomy and traditional laparotomy for patients with uterine fibroids and determine their effect on the pregnancy rate after surgery. In total, 86 cases with uterine fibroids were selected among patients who were admitted in the Zhangqiu District Maternal and Child Health Care Hospital during the period of April, 2016 to April, 2017. Patients who underwent laparoscopic myomectomy were enrolled in group A (n=42), and those who underwent traditional laparotomy were placed in group B (n=44). The general linear data and the operative indicators were compared. The VAS scores, serum IFN-γ, IL-6, VEGF levels and clinical efficacy of the two groups were also compared one week after surgery. Postoperative pregnancy rates and complications in both groups were also compared. No significant differences were observed in general data between the two groups (P>0.05). The intra-operative blood loss in the group A was lower than that in group B (P<0.05), the average time of operation, hospital stays (days), and anal exhaust time in group A were shorter than those in group B (P<0.05). The pain degrees at 3, 6 and 18 h after surgery for patients in the group A were significantly lower than those of the group B (P<0.05). There was no significant difference IL-6 and VEGF levels in the serum between groups A and B before and after surgery (P>0.05); however, the level of IFN-γ expression, one week after surgery, in group B was significantly higher than that in group A (P<0.05). The pregnancy rate in the experimental group was higher than that in the control group (P<0.05), and the incidence rate of complications in group A was significantly lower than that in group B (P<0.05). Results presented in the present study suggested that compared to traditional laparotomy, laparoscopic myomectomy is a more advantageous method in terms of safety, efficacy and pregnancy rate after surgery.

Molecular differential analysis of uterine leiomyomas and leiomyosarcomas through weighted gene network and pathway tracing approaches

Uterine smooth muscular neoplastic growths like benign leiomyomas (UL) and metastatic leiomyosarcomas (ULMS) share similar clinical symptoms, radiological and histological appearances making their clinical distinction a difficult task. Therefore, the objective of this study is to identify key genes and pathways involved in transformation of UL to ULMS through molecular differential analysis. Global gene expression profiles of 25 ULMS, 25 UL, and 29 myometrium (Myo) tissues generated on Affymetrix U133A 2.0 human genome microarrays were analyzed by deploying robust statistical, molecular interaction network, and pathway enrichment methods. The comparison of expression signals across Myo vs UL, Myo vs ULMS, and UL vs ULMS groups identified 249, 1037, and 716 significantly expressed genes, respectively (p ≤ 0.05). The analysis of 249 DEGs from Myo vs UL confirms multistage dysregulation of various key pathways in extracellular matrix, collagen, cell contact inhibition, and cytokine receptors transform normal myometrial cells to benign leiomyomas (p value ≤ 0.01). The 716 DEGs between UL vs ULMS were found to affect cell cycle, cell division related Rho GTPases and PI3K signaling pathways triggering uncontrolled growth and metastasis of tumor cells (p value ≤ 0.01). Integration of gene networking data, with additional parameters like estimation of mutation burden of tumors and cancer driver gene identification, has led to the finding of 4 hubs (JUN, VCAN, TOP2A, and COL1A1) and 8 bottleneck genes (PIK3R1, MYH11, KDR, ESR1, WT1, CCND1, EZH2, and CDKN2A), which showed a clear distinction in their distribution pattern among leiomyomas and leiomyosarcomas. This study provides vital clues for molecular distinction of UL and ULMS which could further assist in identification of specific diagnostic markers and therapeutic targets.Abbreviations UL: Uterine Leiomyomas; ULMS: Uterine Leiomyosarcoma; Myo: Myometrium; DEGs: Differential Expressed Genes; RMA: Robust Multiarray Average; DC: Degree of Centrality; BC: Betweenness of Centrality; CGC: Cancer Gene Census; FDR: False Discovery Rate; TCGA: Cancer Genome Atlas; BP: Biological Process; CC: Cellular Components; MF: Molecular Function; PPI: Protein-Protein Interaction.

Gasless Laparoscopic Myomectomy Using A J-shaped Retractor and Suture Technique

OBJECTIVE

This study aimed to compare gasless single-port access (SPA) laparoscopic myomectomy using a J-shaped retractor and conventional SPA laparoscopic myomectomy.

STUDY DESIGN

The medical records of 60 patients who underwent laparoscopic myomectomy between January 2016 and August 2019 were reviewed. Thirty patients underwent gasless SPA laparoscopic myomectomy using a J-shaped retractor, and 30 patients underwent conventional SPA laparoscopic myomectomy. The 2 groups were compared in terms of surgical outcomes. In gasless laparoscopic myomectomy, closure of the uterine defect after myomectomy was performed using an extracorporeal suture technique with a Kelly clamp and knot pusher.

RESULTS

On comparing gasless SPA and conventional SPA laparoscopic myomectomy, no significant differences were observed in age, body mass index, parity, previous abdominal surgery, and size of the dominant uterine myoma. The median retraction setup time from skin incision was 8 minutes (range, 5 to 15 min) with gasless SPA laparoscopic myomectomy. The median total operation times were 105 minutes (range, 62 to 210 min) with gasless SPA myomectomy and 110 minutes (range, 60 to 270 min) with conventional SPA myomectomy, and there was no significant difference (P=0.251). There was no difference between the groups in terms of estimated blood loss. None of the patients experienced laparotomy conversion in both groups. No major complications, such as urologic, bowel, and vessel injuries, were found in both groups.

CONCLUSION

Gasless SPA laparoscopic myomectomy using a J-shaped retractor is a safe and feasible approach, which allows for easy and convenient suturing of a uterine defect after myomectomy.

Short-term quality of life after myomectomy for uterine fibroids from the COMPARE-UF Fibroid Registry

BACKGROUND

Uterine fibroids may decrease quality of life in a significant proportion of affected women. Myomectomy offers a uterine-sparing treatment option for patients with uterine fibroids that can be performed abdominally, laparoscopically (with or without robotic assistance), and hysteroscopically. Quality of life information using validated measures for different myomectomy routes, especially hysteroscopic myomectomy, is limited.

OBJECTIVE

To compare women's perception of their short-term health-related quality of life measures and reported time to return to usual activities and return to work for different routes of myomectomy.

MATERIALS AND METHODS

Comparing Options for Management: Patient-centered Results for Uterine Fibroids (COMPARE-UF) is a prospective nationwide fibroid registry that enrolled premenopausal women seeking treatment for uterine fibroids at 8 clinical sites. For this analysis, we included women undergoing hysteroscopic, abdominal, or laparoscopic myomectomy who completed the postprocedure questionnaire scheduled between 6 and 12 weeks after surgery. Health-related quality of life outcomes, such as pain, anxiety, and return to usual activitie, were assessed for each route. The hysteroscopic myomectomy group had large differences in demographics, fibroid number, and uterine size compared to the other groups; thus, a direct comparison of quality of life measures was performed only for abdominal and laparoscopic approaches after propensity weighting. Propensity weighting was done using 24 variables that included demographics, quality of life baseline measures, and fibroid and uterine measurements.

RESULTS

A total of 1206 women from 8 COMPARE-UF sites underwent myomectomy (338 hysteroscopic, 519 laparoscopic, and 349 abdominal). All women had substantial improvement in short-term health-related quality of life and symptom severity scores, which was not different among groups. Average symptom severity scores decreased about 30 points in each group. Return to usual activities averaged 0 days (interquartile range, 0-14 days) for hysteroscopic myomectomy, 21 days (interquartile range, 14-28 days) for laparoscopic myomectomy, and 28 days (interquartile range, 14-35 days) for abdominal myomectomy. After propensity adjustment, quality of life outcomes in the laparoscopic and abdominal myomectomy groups were similar except for more anxiety in the laparoscopic myomectomy group and slightly more pain in the abdominal myomectomy group. After propensity weighting, return to usual activities favored laparoscopic compared to abdominal procedures; median time was the same at 21 days, but the highest quartile of women in the abdominal group needed an additional week of recovery (interquartile range,14.0-28.0 for laparoscopic versus 14.0-35.0 for abdominal, P < .01). Time to return to work was also longer in the abdominal arm (median, 22 days; interquartile range, 14-40 days, versus median, 42; interquartile range, 27-56).

CONCLUSION

Women who underwent myomectomy had substantial improvement in health-related quality of life, regardless of route of myomectomy. After propensity weighting, abdominal myomectomy was associated with a nearly 2-week longer time to return to work than laparoscopic myomectomy.

The effects and costs of laparoscopic versus abdominal myomectomy in patients with uterine fibroids: a systematic review and meta-analysis

BACKGROUND

Abdominal myomectomy (AM) and laparoscopic myomectomy (LM) are commonly see surgery for the uterine fibroids, several randomized controlled trials (RCTs) have compared the role of AM and LM, the results remained inconsistent. Therefore, we attempted this meta-analysis to analyze the role of LM versus AM in patients with uterine fibroids.

METHODS

We searched PubMed et al. databases from inception date to July 31, 2019 for RCTs that compared LM versus AM in patients with uterine fibroids. Two authors independently screened the studies and extracted data from the published articles. Summary odd ratios(OR) or mean differences(MD) with 95% confidence intervals(CI) were calculated for each outcome by means of fixed- or random-effects model.

RESULTS

Twelve RCTs with a total of 1783 patients were identified, with 887 patients for and 897 patients for AM. Compared with AM, LM could significantly decrease the blood loss (OR = - 29.78, 95% CI -57.62- - 0.95), shorten the duration of postoperative ileus (OR = - 10.91, 95% CI -18.72- - 3.11), reduce the length of hospital stay (OR = - 1.57, 95% CI -2.05- - 1.08), but LM was associated with longer duration of operation (OR = 16.10, 95% CI 6.52-25.67) and higher medical cost (OR = 17.61, 95% CI 7.34-27.88).

CONCLUSIONS

LM seems to be a better choice for patients with uterine fibroids, more related studies are needed to identify the role of LM and AM for the treatment of uterine fibroids.

Comparison of Reduced-Port Robotic Surgery (RPRS) with conventional 2 port laparoscopy for myomectomy

OBJECTIVE

To compare the surgical outcomes between Reduced-Port Robotic Surgery (RPRS) using the Octo-Port system and conventional 2 port laparoscopy for myomectomy.

STUDY DESIGN

This is a prospective, non-randomized study, which compared and analyzed data from 41 patients who underwent RPRS myomectomy and 22 patients who underwent conventional 2 port laparoscopic myomectomy from April 2016 through July 2019. We compared the myoma enucleation time, suture time, myoma type, and the location of the largest myoma between the two groups.

RESULTS

The patients were not different between the two groups. The myoma enucleation time (26.7 ± 20.9 vs. 22.0 ± 13.7, p = 0.380), hemoglobin drop (2.38 ± 0.9 vs 2.1 ± 0.8, p = 0.280), weight of the myomas (205.3 ± 161.5 vs. 163.4 ± 89.1, p = 0.261), and estimated blood loss (181.1 ± 163.4 vs. 187.3 ± 77.5, p = 0.840) were not significantly different between the two groups. Notably, only the suture time (15.5 (10-21.5) vs. 20 (18-27), p = 0.005) was lesser in women who underwent RPRS myomectomy than in those who underwent conventional 2 port myomectomy.

CONCLUSION

Our data suggest that RPRS myomectomy is comparable to conventional 2 port laparoscopic myomectomy in terms of safety and feasibility and may be more advantageous for suturing after myoma enucleation.

Expanded Somatic Mutation Spectrum of MED12 Gene in Uterine Leiomyomas of Saudi Arabian Women

MED12, a subunit of mediator complex genes is known to harbor genetic mutations, (mostly in exon 2), causal to the genesis of uterine leiomyomas among Caucasian, African American, and Asian women. However, the precise relationship between genetic mutations vs. protein or disease phenotype is not well-explained. Therefore, we sought to replicate the MED12 mutation frequency in leiomyomas of Saudi Arabian women, who represents ethnically and culturally distinct population. We performed molecular screening of MED12 gene (in 308 chromosomes belonging to 154 uterine biopsies), analyzed the genotype-disease phenotype correlations and determined the biophysical characteristics of mutated protein through diverse computational approaches. We discovered that >44% (34/77) leiomyomas of Arab women carry a spectrum of MED12 mutations (30 missense, 1 splice site, and 3 indels). In addition to known codon 44, we observed novel somatic mutations in codons 36, 38, and 55. Most genetically mutated tumors (27/30; 90%) demonstrated only one type of genetic change, highlighting that even single allele change in MED12 can have profound impact in transforming the normal uterine myometrium to leiomyomas. An interesting inverse correlation between tumor size and LH is observed when tumor is positive to MED12 mutation (p < 0.05). Our computational investigations suggest that amino acid substitution mutations in exon-2 region of MED12 might contribute to potential alterations in phenotype as well as the stability of MED12 protein. Our study, being the first one from Arab world, confirms the previous findings that somatic MED12 mutations are critical to development and progression of uterine leiomyomas irrespective of the ethnic background. We recommend that mutation screening, particularly codon 44 of MED12 can assist in molecular diagnostics of uterine leiomyomas in majority of the patients.

Laparoscopic-Assisted Myomectomy with Bilateral Uterine Artery Occlusion/Ligation

STUDY OBJECTIVE

Conventional laparoscopic myomectomy (CLM) and robotic-assisted myomectomy (RAM) are limited in the number and size of myomas that can be removed, whereas abdominal myomectomy (AM) is associated with increased complications and morbidity. Here we evaluated the surgical outcomes of these myomectomy techniques compared with those of laparoscopic-assisted myomectomy (LAM), a hybrid approach that combines laparoscopy and minilaparotomy with bilateral uterine artery occlusion or ligation to control blood loss.

DESIGN

Retrospective chart review (Canadian Task Force classification II-1).

SETTING

Suburban community hospital.

PATIENTS

Women age ≥18 years with nonmalignant indications.

INTERVENTION

A total of 1313 consecutive CLMs, RAMs, AMs, and LAMs performed between January 2011 and December 2013.

MEASUREMENTS AND MAIN RESULTS

Our review included 163 CLMs (12%), 156 RAMs (12%), 686 AMs (52%), and 308 LAMs (23%). Although the average number, size, and total weight of leiomyomas removed were comparable in the LAM and AM groups (9.1, 8.13 cm, and 391 g, respectively, vs 9.0, 7.5 cm, and 424 g; p < .0001), the number and weight of myomas were significantly greater in those 2 groups compared with the CLM and RAM groups (2.9 and 217 g, respectively, and 2.9 and 269 g; p < .0001). The intraoperative complication rate was highest in the RAM group, and the postoperative complication rate was highest in the AM group, both of which were approximately 3 times greater than the rates in the LAM group. There was no statistically significant difference in postoperative complication rates between the CLM and LAM groups.

CONCLUSION

LAM with uterine artery occlusion/ligation is a viable approach for removing large tumor loads while minimizing blood loss and precluding the need for power morcellation.

Feasibility and Compatibility of Minilaparotomy Hysterectomy in a Low-Resource Setting

Introduction

Minilaparotomy hysterectomy (MLH) relies on the simplicity of the traditional open technique of abdominal hysterectomy, imparts cosmesis and faster recovery of laparoscopic hysterectomy yet avoids the long learning curve and cost of expensive setup and instrumentation associated with the minimally invasive approaches, namely, laparoscopy and robotics. In the present study, we tried to ascertain whether the results obtained with MLH can be compared to LAVH in terms of its feasibility, intraoperative variables, and complications. The null hypothesis was that both MLH and LAVH are comparable techniques; thus, where cost and surgeon's experience are the confining issues, patients can be reassured that MLH gives comparable results.

Materials and Methods

This was a prospective observational study done over a period of two years at a university teaching hospital. A total of 65 patients were recruited, but only 52 (MLH: 27; LAVH: 25) could be included in final analysis. All surgeries were performed by one of the two gynecologists with almost equal surgical competence, and outcomes were compared.

Results

MLH is a feasible option for benign gynecological pathologies as none of the patients required increase in the initial incision (4–6 cm). MLH could be done for larger uteri (MLH: 501.30 ± 327.96 g versus LAVH: 216.60 ± 160.01 g; p < 0.001), in shorter duration (MLH: 115.00 ± 21.43 min versus LAVH 172.00 ± 27.91 min; p < 0.001), with comparable blood loss (MLH: 354.63 ±227.96 ml; LAVH: 402.40 ± 224.02 ml; p=0.334), without serious complications when compared to LAVH.

Conclusion

The technique of MLH should be mastered and encouraged to be used in low-resource setting to get results comparable to laparoscopic surgery. This trial is registered with NCT03548831.

Laparoscopic myomectomy and morcellation: A review of techniques, outcomes, and practice guidelines

Laparoscopic myomectomy is a minimally invasive surgical approach to treat symptomatic uterine fibroids in women wishing for a uterine-sparing procedure. With careful patient selection, these procedures are associated with favorable reproductive outcomes and low perioperative morbidity. Current available methods for specimen retrieval include power and hand morcellation. The 2014 FDA safety warnings regarding power morcellation arose from concerns about the spread of occult malignancy and prompted widespread use of containment systems that may limit spread of myometrial cells. Investigation into the clinical effects of laparoscopic myomectomy and uncontained morcellation on the prognosis and spread of occult leiomyosarcoma has yielded mixed results. Other complications of uncontained power morcellation exist, including the development of parasitic leiomyomas. The FDA safety warnings have greatly influenced trends in benign gynecologic surgery, and survey data reflect trends in providers' opinions of these trends. In conclusion, recommendations for the current practice of laparoscopic myomectomy and morcellation are reviewed.

Updated approaches for management of uterine fibroids

Uterine anatomy and uterine fibroids (UFs) characteristics have been classically considered as almost a unique issue in gynecology and reproductive medicine. Nowadays, the management of UF pathology is undergoing an important evolution, with the patient's quality of life being the most important aspect to consider. Accordingly, surgical techniques and aggressive treatments are reserved for only those cases with heavy symptomatology, while the clinical diagnostic based on size and number of UFs remains in a second plane in these situations. Moreover, the development of several noninvasive surgical techniques, especially the appearance of ulipristal acetate as a medical etiological treatment, has substantially changed the clinical indications. As a consequence, after almost 2 decades without relevant updates, it has been necessary to update the protocols for the management of UFs in the Spanish Society of Gynecology and Obstetrics twice. Accordingly, we believe that it is necessary to translate our experience to protocolize the medical care for patients with UFs, incorporating these new therapeutic options, and selecting the best treatment for them. We highlight the importance of achieving the patient's goals and decisions by improving the clinical diagnosis for these type of pathologies, allowing enhanced personalized treatments, as well as the reduction of potential risks and unnecessary surgeries.

Suturing method as a factor for uterine vascularity after laparoscopic myomectomy

OBJECTIVE

To evaluate the vascularity of the myometrium after laparoscopic myomectomy sutured by two different methods using contrast-enhanced Magnetic Resonance Imaging.

STUDY DESIGN

Twenty-eight women who had symptomatic leiomyomas and underwent laparoscopic myomectomy between June 2013 and July 2014 were included in the present study. In the first half period, continuous sutures were used in 12 patients, and in the latter half period, single interrupted sutures were used in 16 patients. Contrast-enhanced Magnetic Resonance Imaging was used 3 or 6 months after surgery to evaluate vascularity after laparoscopic myomectomy. We defined avascularity index as the percentage of avascular area after surgery to cross sectional area of myoma before surgery. The Wilcoxon rank-sum test was applied to compare avascularity indeces in the two study groups.

RESULTS

At 3 months after surgery, avascularity index in continuous sutures group was significantly higher than that in single interrupted sutures group (median 5.0 vs.1.2, p<0.001), suggesting a poorer vascular recovery of the myometrium sutured continuously.

CONCLUSION

Simple interrupted suturing might be superior to continuous suturing in terms of vascularity evaluated using contrast enhanced Magnetic Resonance Imaging.

Uterine fibroid management: from the present to the future

Uterine fibroids (also known as leiomyomas or myomas) are the most common form of benign uterine tumors. Clinical presentations include abnormal bleeding, pelvic masses, pelvic pain, infertility, bulk symptoms and obstetric complications.Almost a third of women with leiomyomas will request treatment due to symptoms. Current management strategies mainly involve surgical interventions, but the choice of treatment is guided by patient's age and desire to preserve fertility or avoid 'radical' surgery such as hysterectomy. The management of uterine fibroids also depends on the number, size and location of the fibroids. Other surgical and non-surgical approaches include myomectomy by hysteroscopy, myomectomy by laparotomy or laparoscopy, uterine artery embolization and interventions performed under radiologic or ultrasound guidance to induce thermal ablation of the uterine fibroids.There are only a few randomized trials comparing various therapies for fibroids. Further investigations are required as there is a lack of concrete evidence of effectiveness and areas of uncertainty surrounding correct management according to symptoms. The economic impact of uterine fibroid management is significant and it is imperative that new treatments be developed to provide alternatives to surgical intervention.There is growing evidence of the crucial role of progesterone pathways in the pathophysiology of uterine fibroids due to the use of selective progesterone receptor modulators (SPRMs) such as ulipristal acetate (UPA). The efficacy of long-term intermittent use of UPA was recently demonstrated by randomized controlled studies.The need for alternatives to surgical intervention is very real, especially for women seeking to preserve their fertility. These options now exist, with SPRMs which are proven to treat fibroid symptoms effectively. Gynecologists now have new tools in their armamentarium, opening up novel strategies for the management of uterine fibroids.

Review of nonsurgical/minimally invasive treatments and open myomectomy for uterine fibroids

PURPOSE OF REVIEW

The main purpose of this review is to collect the most recent evidence with regards to safety and effectiveness of the nonsurgical and minimally invasive treatment options for uterine fibroids.

RECENT FINDINGS

Among the nonsurgical options, uterine artery embolization (UAE), and in eligible patients, magnetic resonance-guided high-intensity focused ultrasound (MRgFUS) are emerging as effective alternatives to surgical options for treatment of symptomatic fibroids. MRgFUS is comparable to UAE, and appears to be a cost effective treatment option, especially in older women, although long-term data are awaited. The transvaginal route for radiofrequency ablation is a promising new nonsurgical alternative, which needs to be studied in larger trials to establish its safety and efficacy.The laparoscopic myomectomy results in less postoperative pain, reduced febrile morbidity, and shorter hospital stay when compared with open laparotomy. The newer robotic approach is comparable to traditional laparoscopic technique in short surgical outcomes but is associated with higher costs. Hysteroscopic myoma resection is an effective surgical intervention for submucous fibroids and prior misoprostol use can help in reducing cervical lacerations.

SUMMARY

UAE and MRgFUS can be offered as an alternative nonsurgical option for eligible women with symptomatic fibroids. Laparoscopic myomectomy remains a safe and effective surgical option with advantage of less postoperative pain and faster recovery compared with open laparotomy for women who wish to retain their fertility options.

Risk, risk reduction and management of occult malignancy diagnosed after uterine morcellation: a commentary

Minimally invasive surgical techniques compared with laparotomy offer the advantages of less intraoperative blood loss, shorter hospitalization, fewer wound complications and faster return to baseline activity for both hysterectomy and myomectomy. While morcellation allows for the laparoscopic removal of large specimens, it may result in intraperitoneal dissemination of benign disease or upstaging of occult malignancy leading to compromised survival. There has been heightened scrutiny over appropriate patient selection and preoperative assessment in light of recent warnings against power morcellation issued by the US FDA. This commentary therefore summarizes the magnitude of such risks associated with uterine morcellation, current national regulatory statements and potential merits of risk-reducing approaches such as contained morcellation. The importance of patient counseling is underscored.
