Comparative analysis of the clinical efficacy and reproductive outcomes of the hysteroscopic tissue removal system (MyoSure) and hysteroscopic electroresection in the treatment of benign intrauterine lesions.

OBJECTIVE: To compare and analyze the clinical efficacy and reproductive outcomes of the hysteroscopic tissue removal system (MyoSure) and hysteroscopic electroresection in the treatment of benign intrauterine lesions in women of reproductive age. METHODS: This is a retrospective study of patients with benign intrauterine lesions treated with MyoSure or hysteroscopic electroresection. The primary outcomes were operative time and resection completeness, and reproductive outcomes were followed up and compared. Secondary outcomes included perioperative adverse events and postoperative adhesions seen during second-look hysteroscopy. Data analysis was performed using χ2 and Fisher tests for qualitative variables and Student t-test for quantitative variables. RESULTS: The operative times of patients with type 0 or I myoma, endometrial polyps, or retained products of conception in the MyoSure group were shorter than those in the electroresection group but were not significantly different for patients with type II myomas. The complete resection rate was lower in the MyoSure group than in the electroresection group. The degree of decrease in the American Fertility Society score of intrauterine adhesion in the MyoSure group was significantly higher (2.90 ± 1.29 points vs 1.31 ± 0.89 points, P = 0.025). The time to pregnancy and the pregnancy rate were higher in the MyoSure group (13.14 ± 7.85 months vs 16.26 ± 8.22 months, P = 0.040; 65.12% vs 54.55%, P = 0.045), but there was no significant difference in the term live birth rate, premature birth rate, or abortion rate between the two groups. CONCLUSION: MyoSure has advantages of a shortened operative time and improvement in reproductive outcomes such as pregnancy rate. However, for type II myomas, MyoSure has limitations, and a comprehensive evaluation before the procedure is required.

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.

Beyond the learning curve: improving outcomes in Robotic myomectomy compared to laparoscopic myomectomy.

Uterine myomas are benign tumours frequently seen in women of reproductive age. Myomectomy remains a viable option for treating this condition in women who wish to preserve their uterus. We undertook this study to compare the peri-operative surgical outcomes of Robotic myomectomy (RM) with laparoscopic myomectomy (LM) in Indian patients of uterine myomas after the initial learning curve of RM was achieved. A retrospective chart review was performed for the patients who underwent RM or LM for the treatment of uterine myomas. A total of 177 patients, 116 in the RM group and 61 in the LM group, were included in the study. The mean age in the RM and LM group was 34.31 ± 5.40 years and 33.54 ± 4.96 years, respectively (p = 0.355). The mean total operative time was marginally more in RM group (127.37 ± 110.67 vs. 120.66 ± 44.27, p = 0.650) but the difference was not statistically significant. Patients in the RM group had significantly less blood loss (115.43 ± 79.43 vs. 340.98 ± 453.9 ml, p = < 0.0001), hospital stay (1.28 ± 0.49 vs. 1.92 ± 1.05 days, p = < 0.0001), requirement of blood transfusion (93.97 vs. 81.97%, p = 0.031) and requirement of intravenous (IV) analgesia (41.38 vs. 34.43%, p = 0.019) as compared to the patients in the LM group. The Robotic myomectomy significantly reduces blood loss, the duration of hospital stay, and requirement of blood transfusions and IV analgesia as compared to the laparoscopic myomectomy.

Use of Barbed Suture in Laparoscopic Myomectomy with Large Posterior Myoma.

OBJECTIVE: To assess the safety and efficacy of barbed suture laparoscopic myomectomy for large posterior myoma compared to conventional suture. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Department of Gynecology, Affiliated Women and Children's Hospital of Ningbo University, Ningbo, Zhejiang, China between July 2019 and June 2020. METHODOLOGY: All cases of laparoscopic myomectomy for large posterior myoma (≥8cm in the largest diametre) were retrospectively reviewed. The surgical technique was identical except the selection of suture material. A comparison between the barbed suture and conventional suture was performed in terms of clinical characteristics and surgical outcomes such as total operative time, suture time, intraoperative blood loss, and changes in hemoglobin concentration. RESULTS: A total of 48 eligible cases, 24 cases with barbed sutures and 24 cases with conventional sutures were included in the final analysis. Patients' clinical characteristics such as age, body mass index, number, and size of myomas were similar between the two groups. In patients with barbed sutures, the time for suturing, the total operative time, intraoperative blood loss, and the changes in hemoglobin concentration were significantly lower than in conventional sutures (all p<0.05). No significant differences in time for enucleation, time for morcellation, and postoperative complications were found between the two groups. Two patients with conventional sutures received postoperative emergent uterine artery embolization and three patients received a blood transfusion. CONCLUSIONS: The use of barbed sutures could reduce the difficulty and enhance safety in laparoscopic myomectomy for large posterior myoma. KEY WORDS: Barbed suture, Laparoscopy, Myomectomy, Posterior.

The role of minimally invasive gynecologic surgeons in the era of subspecialties: when to refer and consult.

PURPOSE OF REVIEW: Minimally invasive gynecologic surgery (MIGS) is a subspecialty focus of obstetrics and gynecology with focused expertise on complex benign gynecologic disorders. To date, no formal recommendations have been made in defining a referral system for MIGS. This article reviews the evidence regarding common disorders and procedures and their outcomes, and posits a basis for MIGS referral. RECENT FINDINGS: In instances where intraoperative and perioperative features may pose clinical challenges to the surgeon and ultimately the patient, the literature suggests the following scenarios may have adverse outcomes, and therefore, benefit from the skills of MIGS subspecialists: fibroids - at least five myomas, myoma size at least 9 cm, and suspected myoma weight at least 500 g; endometriosis - presence of endometrioma(s), suspected stage III/IV endometriosis, and requirement for advanced adjunct procedures; hysterectomy - uteri at least 250 g or 12 weeks estimated size, at least three prior laparotomies, obesity, and complex surgical history with suspected adhesive disease. SUMMARY: A referral system for MIGS subspecialists has proven benefits for both the gynecologic surgical community as well as the patients and their outcomes. This article provides evidence for collaboration with MIGS especially as it relates to leiomyomatous uteri, endometriosis, and complex hysterectomies.

Unexpected coexistent endometriosis in women with symptomatic uterine leiomyomas is independently associated with infertility, nulliparity and minor myoma size.

PURPOSE: To determine risk factors for unexpected coexistent endometriosis in laparoscopic myomectomy for symptomatic uterine leiomyomas. METHODS: This was a single-centre, retrospective cohort study conducted at a University Women's Hospital with a certified endometriosis centre. Data were collected from patients with symptomatic uterine leiomyomas who underwent laparoscopic myomectomy. The main outcome measured in the study was the presence of histologically confirmed endometriosis. Binary regression analysis was used to investigate risk factors for the coexistence of endometriosis. Postoperative complications were classified according to the Clavien-Dindo classification. RESULTS: From 2014 to 2018, 223 patients underwent laparoscopic myomectomy for symptomatic leiomyomas, and 57 (25.6%) had unexpected endometriosis. Women with endometriosis significantly more frequently were nulliparous (66.7% vs. 51.2%; p = 0.04), had reported infertility (31.6% vs. 15.7%; p = 0.01) and smaller leiomyomas (mean diameter 4.92 cm) than women without endometriosis (mean diameter 6.02 cm; p = 0.006). Coexistent endometriosis significantly increased mean operative time (168.4 vs. 142.8 min; p = 0.05) while intra- and postoperative complications showed a similar distribution (p = 0.87) and length of hospital stay (p = 0.26). Binary regression analysis identified 2.3- and 2.2-fold increases in the risk of endometriosis for infertility (p = 0.042) and nulliparity (p = 0.041), respectively. Myoma size influenced the risk of endometriosis by a factor of 0.8 per cm (p = 0.037). CONCLUSIONS: Coexistent endometriosis should be expected in leiomyoma patients particularly with nulliparity, infertility or minor myoma size as independent risk factors. Preoperative counselling should incorporate surgical therapy of coexisting endometriosis.

Prevention and Management of Complications in Laparoscopic Myomectomy.

Myomectomy aims to preserve fertility, treat abnormal uterine bleeding, and alleviate pain. It should cause minimal damage to the endometrium, while being tolerable and durable, and reduce the incidence of myoma recurrence and complications including bleeding, hematoma, adhesions, and gravid uterus perforation. Training and experience are crucial to reduce complications. The surgical strategy depends on imaging information on the myomas. The position of the optical and secondary ports will determine the degree of ergonomic surgery performance, time and difficulty of myoma enucleation, and the suturing quality. Appropriate hysterotomy length relative to myoma size can decrease bleeding, coagulation, and suturing times. Bipolar coagulation of large vessels, while avoiding carbonization and myometrium gaps after suturing, may decrease the risk of myometrial hematoma. Quality surgery and the use of antiadhesive barriers may reduce the risk of postoperative adhesions. Slow rotation of the beveled morcellator and good control of the bag could reduce de novo myoma and endometriosis. Low intra-abdominal CO2 pressure may reduce the risk of benign and malignant cell dissemination. The benefits a patient gains from laparoscopic myomectomy are greater than the complication risks of laparoscopic morcellation. Recent publications on laparoscopic myomectomies demonstrate reduced hospitalization stays, postoperative pain, blood loss, and recovery compared to open surgery.

Multimodal imaging for diagnosis and management of parasitic peritoneal myoma with myxoid degeneration after laparoscopic-assisted myomectomy with electric power morcellation.

A 45-year-old multipara woman was referred due to the rapid enlargement of an asymptomatic pelvic mass that was detected during a regular check up. She had undergone laparoscopic-assisted myomectomy 15 years previously. At the time, the uncontained extraction of an intraligamental myoma with electric power morcellation had been performed. Multimodal imaging revealed a heterogeneous mass in the vesicouterine pouch that was found to be supplied by the left gastro-omental and superior vesical arteries. Although malignancy could not be completely denied, parasitic peritoneal myoma with myxoid degeneration was the most probable diagnosis. Single-port laparoscopic excision of the peritoneal mass was performed along with laparoscopic-assisted vaginal hysterectomy and bilateral salpingo-oophorectomy. The excised peritoneal mass was placed into a retrieval bag and extracted through the vagina. The pathological diagnosis was a parasitic peritoneal myoma with myxoid degeneration. The postoperative course was uneventful, and there was no recurrence of parasitic myoma in the 1-year follow up after surgery.

Alcohol consumption and risk of uterine myoma: A systematic review and meta analysis.

BACKGROUND: The published data about alcohol consumption and uterine myoma are scanty and controversial: some studies found positive association whereas other studies showed no association. OBJECTIVES: To conduct a systematic review and meta-analysis to determine whether alcohol is a risk factor for myoma. SEARCH STRATEGY: A MEDLINE/EMBASE search was carried out, supplemented by manual searches of bibliographies of the selected studies. SELECTION CRITERIA: Articles published as full-length papers in English. In the review we included all identified studies. Otherwise, the inclusion criteria for studies included in the meta-analysis were: a) case-control or cohort studies, reporting original data; b) studies reporting original data on the association between alcohol consumption and myoma; c) diagnosis of myoma was ultrasound or histological confirmed and/or clinically based. DATA COLLECTION AND ANALYSIS: A total of 6 studies were identified for the review and 5 studies were included in the meta-analysis. The primary outcome was the incidence of uterine myoma in ever versus never alcohol drinkers and when data were available, we also analyzed categories of alcohol intake. We assessed the outcomes in the overall population and then we performed a subgroup analysis according to study design. Pooled estimates of the odds ratios (OR) with 95% confidence interval (CI) were calculated using random effects models. MAIN RESULTS: The summary OR (95%CI) of myoma forever versus never alcohol intake was 1.12 (0.94-1.34) with significant heterogeneity. The summary OR for current versus never drinking was 1.33 (1.01-1.76) with no heterogeneity. CONCLUSIONS: Ever alcohol consumption is not associated with myoma risk. Based on the data of two studies, current alcohol drinkers had a slightly borderline increased risk of diagnosis of myoma. In consideration of the very limited number of studies and the suggestion of a potential increased risk among current drinkers, further studies are required.

Dolor pélvico de origen ginecológico como patología urgente / Gynecological pelvic pain as emergency pathology

El dolor pélvico agudo es una causa frecuente de consulta en los servicios de urgencias. Los síntomas inespecíficos hacen que a menudo se encuentre patología ginecológica en pacientes remitidas por otras sospechas diagnósticas. Por eso es importante familiarizarse con este tipo de patología y ser capaces de identificar sus hallazgos más representativos. El objetivo de este artículo es revisar las principales causas del dolor pélvico agudo de origen ginecológico, aportando datos clave que permitan establecer un diagnóstico acertado y orientar el tratamiento adecuado (AU)

The purpose of this article is review the main causes of gynecological acute pelvic pain and their radiologic appearances to be able to make an accurate diagnosis and provide objective criteria for patient management (AU)

Patients' beliefs about the causes of myomas: a pilot study from a large European city.

INTRODUCTION: Patients usually develop subjective concepts about their illness, which then influences their further health behaviors and treatment decisions. This study aimed to evaluate several possible patient beliefs about the causal factors of illness, in a large sample of women seeking treatment for myomas. METHODS: From November 2011 to October 2013, all patients at a specialized myoma clinic in a large European city were surveyed about their beliefs about the causes of myomas. We used a modified version of the Patient Theory Questionnaire from Zenz et al., which presented 16 of the most common possible beliefs about the causes of myomas, and asked patients to rate them on a five-point scale of likelihood. Retrospectively, statistical analysis was performed on their answers and sociodemographic data. RESULTS: Data from 482 patients was included (return rate of 91.5%). The most frequent answers for possible causes were "inherited susceptibility for myomas" (67.3%), "reorganization in the body during a particular phase of life" (63.5%), "stress at work or home" (49.3%) and "an in-born tendency to react to emotional agitation with physical disorders" (41.8%). Significant differences were found for the factors of age, immigration background and self-rated knowledge about myomas. CONCLUSIONS: It is curious that two of the four most common explanations for myomas were stress and somatization, and were endorsed by nearly half of all patients. Physicians seeing women for myomas should consider that many such patients may have further hidden reasons for seeking medical care.

Oestrogen-induced angiogenesis and implantation contribute to the development of parasitic myomas after laparoscopic morcellation.

BACKGROUND: Iatrogenic parasitic myomas (PMs), caused by intra-corporeal power morcellation during laparoscopy is gradually increasing. However, the pathogenesis and medical treatment of PMs remain largely unelucidated. METHODS: Laparoscopically-induced PM xenografted mouse model was conducted by xenografting human uterine myoma fragments into the abdominal cavity of SCID mice and hormonal manipulation was performed using this mouse model to demonstrate the role of oestrogen in the development of implanted PMs. Immunohistochemistry of oestrogen receptor α (ERα), progesterone receptor (PR), vimentin, vascular endothelial growth factor (VEGF), microvessel density (MVD) and Ki-67 index was performed and compared. RESULTS: In the patient with PMs, ERα, PR, angiogenesis and proliferative property expression were upregulated in PM lesions compared to uterine myomas. In the laparoscopically-induced PM mouse model, implanted myomas had more steroid receptor expressions, angiogenesis and proliferative property compared with pre-xenografted or non-implanted myoma. Depletion of oestrogen in the ovariectomized (OVX) mice decreased laparoscopically-induced PM implantations. In comparison, the implantations of PMs were increased with additional E2 supplement. Hormonal manipulation in the PM mouse model, including AI, GnRHa and SERM groups, were compared and AI significantly decreased the implantations, steroid receptor, angiogenesis, cell density, and proliferative index of PMs compared with control group. Furthermore, GnRHa significantly decreased VEGF and MVD expressions compared with control group. CONCLUSIONS: These data highlight the crucial role of oestrogen in the development of laparoscopically-induced PMs and suggest that hormone manipulation may be a potential therapeutic agent. TRIAL REGISTRATION: This protocol was approved by the Human and Animal Institutional Review Board of Taipei Veterans General Hospital ( VGHIRB No 2014-10-002C on Nov. 17th, 2014; IACUC 2014-119 on Aug. 22nd, 2014).

Parasitic myomas after laparoscopic-assisted myomectomy in multiple endocrine neoplasia type 1.

Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant hereditary disorder that develops multiple tumors arising from various endocrine organs, including the parathyroid gland, endocrine pancreas and pituitary gland. Although mesenchymal tumors can be an integral part of the syndrome, parasitic peritoneal myomas have never been described in an MEN1 patient. Seven years after laparoscopic-assisted myomectomy, parasitic peritoneal myomas were diagnosed in a 31-year-old woman with situs inversus totalis and previous history of parathyroid adenoma. Subsequently, MEN1 was clinically diagnosed by identification of endocrine pancreatic, adrenal and pituitary tumors. Genetic analysis revealed a heterozygous germline mutation in the splice donor sequence of intron 6 of the MEN1 gene. Although rare, parasitic peritoneal myomas could potentially be associated with MEN1 syndrome.

Myomas and reproductive function.

The purpose of this Educational Bulletin is to examine the relationship between myomas and reproductive function and to review current methods for their management.

Etiology, symptomatology, and diagnosis of uterine myomas.

OBJECTIVE: To review the currently available literature regarding the biology, etiology, symptoms, and diagnosis of uterine myomas. DESIGN: Literature review of 220 articles pertaining to uterine myomas. RESULT(S): Although uterine myomas presently are not well understood, many advances have been made in the understanding of the hormonal factors, genetic factors, growth factors, and molecular biology of these benign tumors. Prospective, longitudinal studies are underway to characterize the risk factors for their development. When needed, the position of myomas can be best imaged by sonohysterography or magnetic resonance imaging. Evidence suggests that only submucous myomas appear to interfere with fertility, and only very rarely do myomas effect pregnancy outcome. CONCLUSION(S): A summary of the available literature regarding the biology, etiology, symptomatology, and diagnosis of myomas shows that, although they are still not well understood, much has been learned about uterine myomas.

Perivascular myoma of myopericytoma and myofibromatosis-type arising in a chronic scar.

We describe a case of a cutaneous perivascular myoma with features overlapping between the myofibromatosis and the myopericytoma type. The patient is a 58-year-old woman with a painless plaque-like and multinodular lesion in the pretibial dermis and subcutaneous tissue. She had repeated trauma to this site, first in her early youth that left an area of hyperpigmentation, and then again at age 40. The biopsy showed a biphasic pattern with a myofibromatosis-type component composed of spindle cell myoid nodules and more cellular round cell areas. The myopericytoma-like areas appeared to be infiltrating along vessels. These areas contained aggregates of immature-appearing cells arranged concentrically around vascular lumina in a manner reminiscent of pericytes. Immunohistochemical stains showed focal positivity for smooth muscle actin. Immunohistochemical and ultrastructural studies have showed these pericyte-like cells to be of a myoid origin. The reason for the neoplastic proliferation of perivascular myoid cells is presently unknown. The association of trauma and neoplastic transformation of the skin is rare. We report the first case of a cutaneous perivascular myoma arising in a chronic scar.
