It is a common obstetric tragedy in our delivery rooms in countries with limited resources, reflecting the poor quality of obstetric care and, consequently, an unmet obstetric need. Methods: This was a descriptive and analytical cross-sectional study with prospective data collection over a four-year period from 1 January 2020 to 31 December 2023 at the University Hospital Centre (CHU) of Bouaké, in the Obstetrics and Gynaecology Department. The variables studied were epidemiological characteristics, therapeutic aspects and factors associated with maternal. Results: The prevalence of uterine rupture was 0.63%. The average age was 32, with patients aged 35 and over accounting for 33.68%, married 44.21% and 70% not in education. Patients with uterine rupture had been evacuated in 85.26% of cases. Uterine rupture was diagnosed in 97.89% of cases during labour. Maternal lethality due to rupture was 15.79%. The causes of maternal death were dominated by haemorrhagic shock (53.33%). Factors statistically associated with death were age ≥ 35 years (OR: 3.14), duration of labour ≥ 12 hours (OR: 5.8), multiparity (OR: 19.04), admission delay beyond 2 hours (OR: 4.36), haemoglobin level ≤ 7 g/dl (OR: 36.84), coma or obnubilation (OR: 71.82), haemorrhagic shock (OR: 243.94) and occurrence of post-operative complications (OR: 76.45). Conclusion: The frequency of uterine rupture remains significant in the department (0.63%), with maternal mortality still high (15.79%). The key to reducing uterine rupture and its consequences lies in timely referral and early, appropriate management.展开更多

Despite their commonality, the epidemiology and clinical patterns of leiomyomas in Puerto Rico remain inadequately researched. Methods: This study conducted a secondary data analysis using clinical, menstrual cycle characteristics, and demographic data from self-administered questionnaires of women undergoing diagnostic laparoscopy for endometriosis in Puerto Rico. Chi-square tests and t-tests analyzed categorical and continuous variables, respectively (p Results: Among 1,610 endometriosis cases, 312 included uterine fibroids. Prevalence estimates were 10.3% (40 years). Primiparous women averaged 22.14 years, with 40.71% having 2 - 3 pregnancies and 26.28% experiencing miscarriages. Symptoms included infertility (29.5%), dyspareunia (40.7%), severe pain (50%), and dysmenorrhea (75.6%). Comorbidities included ovarian cysts (52.2%) and abnormal uterine bleeding (37.8%). Conclusions: Advanced age, parity, and comorbidities like diabetes and hypertension were prevalent in our cohort. Understanding the epidemiological profile of women living in Puerto Rico with uterine fibroids is crucial for improving diagnostic awareness and enhancing patient care.展开更多

文摘In this article,we comment on the paper by Kakinuma et al published recently.We focus specifically on the diagnosis of uterine pseudoaneurysm,but we also review other uterine vascular anomalies that may be the cause of life-threating hemorrhage and the different causes of uterine pseudoaneurysms.Uterine artery pseudoaneurysm is a complication of both surgical gynecological and nontraumatic procedures.Massive hemorrhage is the consequence of the rupture of the pseudoaneurysm.Uterine artery pseudoaneurysm can develop after obstetric or gynecological procedures,being the most frequent after cesarean or vaginal deliveries,curettage and even during pregnancy.However,there are several cases described unrelated to pregnancy,such as after conization,hysteroscopic surgery or laparoscopic myomectomy.Hemorrhage is the clinical manifestation and it can be life-threatening so suspicion of this vascular lesion is essential for early diagnosis and treatment.However,there are other uterine vascular anomalies that may be the cause of severe hemorrhage,which must be taken into account in the differential diagnosis.Computed tomography angiography and embolization is supposed to be the first therapeutic option in most of them.
文摘This article provides a detailed account of the diagnosis and treatment of a case involving a uterine artery pseudoaneurysm(UAP),as well as an analysis of UAP etiology.This finding emphasizes that UAP should be considered in patients presenting with abnormal genital bleeding after hysteroscopy and offers valuable insights and lessons for gynecologists in hysteroscopic procedures.The patient underwent timely relevant examinations to confirm the diagnosis,allowing for crucial time required for her treatment.In this study,the primary cause of UAP formation in the patient was attributed to a prior hysteroscopic surgical procedure conducted at another medical facility,suggesting that the selection and imple-mentation of dilatation catheters are some of the predisposing factors for UAP.In conclusion,this case study offers a comprehensive analysis of the etiology of UAP and effectively provides timely diagnosis and treatment,offering valuable in-sights for the clinical diagnosis and management of UAP.

文摘BACKGROUND Uterine injury can cause uterine scarring,leading to a series of complications that threaten women’s health.Uterine healing is a complex process,and there are currently no effective treatments.Although our previous studies have shown that bone marrow mesenchymal stem cells(BMSCs)promote uterine damage repair,the underlying mechanisms remain unclear.However,exploring the specific regulatory roles of BMSCs in uterine injury treatment is crucial for further understanding their functions and enhancing therapeutic efficacy.AIM To investigate the underlying mechanism by which BMSCs promote the process of uterine healing.METHODS In in vivo experiments,we established a model of full-thickness uterine injury and injected BMSCs into the uterine wound.Transcriptome sequencing was per-formed to determine the enrichment of differentially expressed genes at the wound site.In in vitro experiments,we isolated rat uterine smooth muscle cells(USMCs)and cocultured them with BMSCs to observe the interaction between BMSCs and USMCs in the microenvironment.RESULTS We found that the differentially expressed genes were mainly related to cell growth,tissue repair,and angiogenesis,while the phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT)pathway was highly enriched.Quantitative reverse-transcription polymerase chain reaction was used to validate differentially expressed genes,and the results demonstrated that BMSCs can upregulate genes related to regeneration and downregulate genes related to inflammation.Coculturing BMSCs promoted the migration and proliferation of USMCs,and the USMC microenvironment promoted the myogenic differentiation of BMSCs.Finally,we validated the PI3K/AKT pathway in tissues and cells and showed that BMSCs activate the PI3K/AKT pathway to promote the regeneration of uterine smooth muscle both in vivo and in vitro.CONCLUSION BMSCs upregulated uterine wound regeneration and anti-inflammatory factors and enhanced uterine smooth muscle proliferation through the PI3K/AKT pathway both in vivo and in vitro.

文摘BACKGROUND The classification of uterine sarcomas is based on distinctive morphological and immunophenotypic characteristics,increasingly supported by molecular genetic diagnostics.Data on neurotrophic tyrosine receptor kinase(NTRK)gene fusionpositive uterine sarcoma,potentially aggressive and morphologically similar to fibrosarcoma,are limited due to its recent recognition.Pan-TRK immunohistochemistry(IHC)analysis serves as an effective screening tool with high sensitivity and specificity for NTRK-fusion malignancies.CASE SUMMARY We report a case of a malignant mesenchymal tumor originating from the uterine cervix,which was pan-TRK IHC-positive but lacked NTRK gene fusions,accompanied by a brief literature review.A 55-year-old woman presented to the emergency department with abdominal pain and distension,exhibiting significant ascites and multiple solid pelvic masses.Pelvic examination revealed a tumor encompassing the uterine cervix,extending to the vagina and uterine corpus.A punch biopsy of the cervix indicated NTRK sarcoma with positive immunochemical pan-TRK stain.However,subsequent next generation sequencing revealed no NTRK gene fusion,leading to a diagnosis of poorly differentiated,advanced-stage sarcoma.CONCLUSION The clinical significance of NTRK gene fusion lies in potential treatment with TRK inhibitors for positive sarcomas.Identifying such rare tumors is crucial due to the potential applicability of tropomyosin receptor kinase inhibitor treatment.
文摘BACKGROUND Uterine adenomyosis and pulmonary endometriosis are exceptionally rare in adolescents and can pose significant diagnostic challenges due to their nonspecific clinical presentation and imaging features,which may mimic malignancy.Here,we describe a case of adenomyosis-associated uterine rupture(secondary to hemorrhagic necrosis)and concurrent pulmonary endometriosis in a 16-year-old girl initially suspected of having advanced uterine cancer.CASE SUMMARY A 16-year-old girl presented with acute abdominal pain and oliguria.Imaging studies revealed a 15-cm ruptured uterine mass accompanied by hemoperitoneum and multiple pulmonary nodules suggestive of metastatic disease.Laboratory tests demonstrated severe anemia and markedly elevated tumor markers[cancer antigen(CA)-125:1063 U/mL;CA-19-9:1347 U/mL].Emergency laparotomy revealed adenomyosis-associated uterine rupture secondary to hemorrhagic necrosis,with no macroscopic abnormalities in other organs.A total abdominal hysterectomy was performed.Histopathological analysis confirmed uterine adenomyosis with hemorrhagic necrosis.Subsequent thoracoscopic wedge resections of the pulmonary lesions demonstrated histologically confirmed endometriosis.The patient has remained disease-free under treatment with oral dienogest.CONCLUSION This case of an adolescent patient highlights how benign gynecological conditions can mimic malignancy,necessitating broad differential diagnoses despite alarming presentations.
文摘BACKGROUND Pre-eclampsia is a significant challenge in obstetric care and adversely affects the feto-maternal outcomes,causing significant perinatal morbidity and mortality.Early detection of women at higher risk of developing pre-eclampsia in the first trimester provides a vital opportunity to initiate timely prophylactic therapies.First-trimester uterine artery Doppler is gaining prominence as a promising tool in early risk stratification.AIM To assess the role of uterine artery Doppler in screening for pre-eclampsia at 11-14 weeks of gestation.METHODS Pregnant women attending routine antenatal care between 11 weeks and 14 weeks of gestation and undergoing first-trimester nuchal translucency screening were offered enrolment in the study.After calculating gestational age from the last menstrual period or fetal biometry(crown-rump length),Doppler ultrasound of bilateral uterine arteries was performed,and relevant Doppler parameters were recorded.Patients were followed until delivery for development of preeclampsia.RESULTS Out of a total of 342 participants,42 women(12.28%)developed preeclampsia,while the remaining 300 women(87.71%)had a normal pregnancy without preeclampsia.The mean uterine artery pulsatility index was significantly elevated in the pre-eclampsia group(1.9455±0.36)compared to the normal group(1.474±0.52)(P<0.001).Using a pulsatility index threshold of 1.622,the receiver operating characteristic curve analysis demonstrated a sensitivity of 75%(95%confidence internal:0.66-0.82),specificity of 86%(95%confidence internal:0.78-0.91),positive predictive value of 84.27%,and negative predictive value of 77.48%with a diagnostic accuracy of 80.5%.The area under the curve was 0.896,indicating good diagnostic performance.Uterine artery notching was observed in 88%of the pre-eclampsia group compared to 16%in the control group,a difference that was statistically significant(P<0.001).CONCLUSION Uterine artery Doppler in the first trimester at 11-14 weeks of gestation showed a good diagnostic value for forecasting the development of pre-eclampsia and holds promise as a valuable tool for early risk stratification.
文摘BACKGROUND Intramural pregnancy is rare,with an unclear etiology and pathophysiology.Surgical,medical,and expectant management options are available for this condition.However,most reported cases are managed surgically.Despite the risks of massive intraoperative bleeding and acute and long-term complications,uterine artery embolization is often selected.Temporary occlusion of the bilateral uterine arteries during surgery is associated with fewer complications.CASE SUMMARY We reported the case of a patient who was diagnosed with intramural pregnancy approximately one month after medical abortion.We performed laparoscopic resection with hysteroscopy.Since the lesion had abundant blood flow,we temporarily blocked the bilateral uterine arteries to prevent massive intraop-erative bleeding.The surgical process went smoothly.The postoperative course was uneventful.CONCLUSION Temporary occlusion of the bilateral uterine arteries in the treatment of intramural pregnancy may prevent excessive uterine bleeding during surgery.
文摘Objective:To investigate the delivery modes of women with repeat pregnancies involving uterine scars and their effects on both mothers and neonates.Methods:A study was conducted on 100 patients treated at Shenzhen Maternity and Child Healthcare Hospital from July 2023 to July 2024.The participants were divided into a control group and an observation group,with 50 cases in each.The division was based on the indications for prior cesarean section,cervical maturity,postpartum complications,and thickness of the cesarean scar.The control group underwent cesarean delivery,while the observation group experienced vaginal delivery.The two groups were compared in terms of intrapartum blood loss,postpartum blood loss within 2 hours,length of hospital stay,Apgar scores at 1-minute post-birth,and incidences of neonatal fever and jaundice.Results:The observation group had significantly lower intrapartum blood loss,postpartum blood loss within 2 hours,and shorter hospital stays compared to the control group(P<0.05).Additionally,the Apgar scores at 1 minute post-birth were significantly higher in the observation group(P<0.05).The incidence of neonatal fever and jaundice was significantly lower in the observation group(P<0.05).These differences were statistically significant.Conclusion:Vaginal delivery has high clinical value for women with repeat pregnancies involving uterine scars.It reduces maternal intrapartum and postpartum blood loss,shortens hospital stays,improves neonatal Apgar scores,and decreases the incidences of neonatal fever and jaundice.This method is worthy of clinical application and promotion.

文摘Background Uterine aging is a key factor contributing to the deterioration of egg quality and reproductive performance in laying hens.Despite its importance,the molecular mechanisms underlying uterine aging remain poorly defined.This study aimed to characterize gene expression and regulatory changes associated with uterine aging in hens at different life stages.Results Transcriptomic Analysis of uterine tissue from hens aged 350,500,And 700 d revealed dynamic changes in gene expression patterns during aging.A significant upregulation of genes involved in cellular senescence was observed,including increased expression of the p53 signaling pathway And markers associated with inflammation And cell cycle arrest.The most notable changes occurred between 350 And 500 d of age,suggesting this as a critical window for the onset of uterine aging.MicroRNA sequencing identified miR-210a-5p as significantly reduced with age.Target prediction and experimental validation showed that miR-210a-5p directly suppresses the expression of RASL11B,a Ras-like small GTPase that activates the MAPK signaling pathway.In primary uterine epithelial cells,reduced miR-210a-5p levels led to elevated RASL11B expression,increased activation of B-Raf,MEK,and ERK proteins,and enhanced expression of aging-related genes and inflammatory factors.In contrast,overexpression of miR-210a-5p or inhibition of the MAPK pathway delayed senescence and reduced inflammatory signaling.RASL11B overexpression was sufficient to induce aging phenotypes,confirming its central role in promoting uterine cellular aging.Conclusions This study identifies a novel regulatory pathway in which miR-210a-5p modulates uterine aging through the RASL11B-MAPK signaling cascade.The findings provide mechanistic insight into age-related reproductive decline in hens and suggest that targeting this pathway may offer new strategies for maintaining uterine function and extending reproductive lifespan in poultry.
文摘OBJECTIVE:To evaluate the clinical outcome of Traditional Chinese Medicine(TCM)syndrome differentiation combined with hysteroscopic treatment for uterine incision defect after cesarean section[previous cesarean scar defect(PCSD)]after cesarean section.METHODS:This is a single-center retrospective study.A total of 120 PCSD patients were enrolled from February 2022 to February 2023 and divided into two groups according to different treatment methods,the TCM group(n=60)and the control group(n=60).The control group was treated with hysteroscopy,and the TCM group combined TCM syndrome differentiation with hysteroscopy.Clinical outcome included menstrual scores,menstrual days,TCM symptom scores and intrauterine pregnancy recurrence rate was analyzed in two groups.RESULTS:The total response rate of the TCM group was significantly higher than that of the control group(P<0.05);after treatment,the menstrual scores,menstrual days and TCM symptoms of the two groups were decreased,and the menstrual scores,menstrual days and TCM symptoms of the TCM group were all lower than that of the control group(P<0.05);the recurrence rate of the TCM group was significantly lower than that of the control group(P<0.05).Follow-up results showed higher healing of incisional scar diverticulum in the TCM group than in the control group(P<0.05).The duration of menstruation before and after treatment,and the TCM group was better than the control group(P<0.05).CONCLUSION:TCM syndrome differentiation combined with hysteroscopy presented favorable outcome on the prolonged menstrual period of PCSD,which could significantly improve the recovery of menstruation,relief the symptoms of TCM,reduce the recurrence rate and accelerate wound healing.
文摘Introduction: Uterine rupture is certainly one of the most serious, as it immediately jeopardises the vital prognosis of the mother and foetus. It is a common obstetric tragedy in our delivery rooms in countries with limited resources, reflecting the poor quality of obstetric care and, consequently, an unmet obstetric need. Methods: This was a descriptive and analytical cross-sectional study with prospective data collection over a four-year period from 1 January 2020 to 31 December 2023 at the University Hospital Centre (CHU) of Bouaké, in the Obstetrics and Gynaecology Department. The variables studied were epidemiological characteristics, therapeutic aspects and factors associated with maternal. Results: The prevalence of uterine rupture was 0.63%. The average age was 32, with patients aged 35 and over accounting for 33.68%, married 44.21% and 70% not in education. Patients with uterine rupture had been evacuated in 85.26% of cases. Uterine rupture was diagnosed in 97.89% of cases during labour. Maternal lethality due to rupture was 15.79%. The causes of maternal death were dominated by haemorrhagic shock (53.33%). Factors statistically associated with death were age ≥ 35 years (OR: 3.14), duration of labour ≥ 12 hours (OR: 5.8), multiparity (OR: 19.04), admission delay beyond 2 hours (OR: 4.36), haemoglobin level ≤ 7 g/dl (OR: 36.84), coma or obnubilation (OR: 71.82), haemorrhagic shock (OR: 243.94) and occurrence of post-operative complications (OR: 76.45). Conclusion: The frequency of uterine rupture remains significant in the department (0.63%), with maternal mortality still high (15.79%). The key to reducing uterine rupture and its consequences lies in timely referral and early, appropriate management.

文摘Uterine artery pseudoaneurysm(UAP)is a rare but potentially life-threatening complication that can occur following hysteroscopic surgery for endometrial polyp resection.This article discusses the case study by Kakinuma et al,which highlights the successful diagnosis and treatment of UAP in a 48-year-old primiparous woman.Utilizing advanced imaging techniques such as ultrasound and computed tomography(CT),the medical team was able to promptly identify the UAP and subsequently perform a uterine artery embolization to treat the condition.The study underscores the critical need for rapid diagnosis and intervention to prevent severe outcomes and provides practical clinical recommendations for managing similar cases.This article aims to expand on the study’s findings,discuss the clinical implications,and suggest future research directions to optimize the management of UAP post-hysteroscopic surgery.
文摘BACKGROUND By comprehensively analyzing the blood flow parameters of the umbilical and middle cerebral arteries,doctors can more accurately identify fetal intrauterine distress,as well as assess its severity,so that timely interventions can be implemented to safeguard the health and safety of the fetus.AIM To identify the relationship between ultrasound parameters of the umbilical and middle cerebral arteries and intrauterine distress.METHODS Clinical data of pregnant women admitted between January 2021 and January 2023 were collected and divided into the observation and control groups(n=50 each),according to the presence or absence of intrauterine distress.The ultrasound hemodynamic parameters of the uterine artery(UtA),fetal middle cerebral artery(MCA),and umbilical artery(UmA)were compared with neonatal outcomes and occurrence of intrauterine distress in the two groups.RESULTS Comparison of ultrasonic hemodynamic parameters,resistance index(RI),pulsatility index(PI),and systolic maximal blood flow velocity of UmA compared to diastolic blood flow velocity(S/D),revealed higher values of fetal MCA,PI,and S/D of UmA in pregnant women with UtA compared to controls(P<0.05),while there was no difference between the two groups in terms of RI(P<0.05)The incidence of a neonatal Apgar score of 8-10 points was lower in the observation group(66.7%)than in the control group(90.0%),and neonatal weight(2675.5±27.6 g)was lower than in the control group(3117.5±31.2 g).Further,cesarean section rate was higher in the observation group(70.0%)than in the control group(11.7%),and preterm labor rate was higher in the observation group(40.0%)than in the control group(10.0%).The incidence of fetal distress,neonatal growth restriction and neonatal asphyxia were also higher in the observation group(all P<0.05).CONCLUSION Fetal MCA,UmA,and maternal UtA hemodynamic abnormalities all develop in pregnant women with intrauterine distress during late pregnancy,which suggests that clinical attention should be paid to them,and monitoring should be strengthened to provide guidance for clinical intervention.
文摘BACKGROUND We report a case of uterine artery pseudoaneurysm(UAP)occurrence during hysteroscopic endometrial polypectomy and its treatment via uterine artery embolization(UAE).CASE SUMMARY A 48-year-old primigravid,primiparous patient was incidentally found to have an endometrial polyp during a health checkup,and underwent a hysteroscopic polypectomy at another hospital.Her cervix was dilated with a Laminken-R®device.After the Laminken-R®was withdrawn,a large amount of genital bleeding was observed.This bleeding persisted after the hysteroscopic polypectomy,and,as hemostasis became impossible,the patient was transferred to our hospital by ambulance.On arrival,transvaginal ultrasonography revealed a 3-cm hypoechoic mass with a swirling internal pulse on the right side of the uterus,and color Doppler ultrasonography showed feeder vessels penetrating the mass.Pelvic contrast-enhanced computed tomography(CT)confirmed the presence of a mass at this site,and vascular proliferation was observed within the uterine cavity.Consequently,UAP was diagnosed,and UAE was performed.The patient’s postoperative course was uneventful,and 6 mo post-UAE,no recurrence of blood flow to the UAP was observed.CONCLUSION When abnormal genital bleeding occurs during hysteroscopic surgery,ultrasonography and contrast-enhanced CT can assist in the detection of early UAPs.

文摘Uterine fibroids are benign tumors that originate from smooth muscle cells of the uterus.It is the most common gynecological disorder,affecting up to 80%of women of reproductive age.Uterine fibroids can cause various symptoms such as abnormal uterine bleeding,pelvic pain,infertility,and pregnancy complications.The treatment options for uterine fibroids include medical therapy,surgical intervention,and minimally invasive techniques.AIM To compare ovarian function of women with uterine fibroids who did or did not undergo uterine artery embolization(UAE).METHODS This prospective cohort study enrolled 87 women with symptomatic uterine fibroids who underwent UAE,and 87 women with the same symptoms who did not undergo UAE but received conservative management or other treatments.The two groups were matched for age,body mass index,parity,and baseline characteristics of uterine fibroids.The primary outcome was ovarian function that was evaluated by serum levels of follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),and anti-Müllerian hormone(AMH),as well as ovarian reserve tests,such as antral follicle count(AFC)and ovarian volume(OV).The secondary outcome was fertility that was evaluated based on the menstrual cycle,ovulation,conception,pregnancy,and delivery.The participants were followed-up for 36 months and assessed at 1,3,6,12,24,and 36 months after treatment.RESULTS The study found that the most common minor complication of UAE was postembolization syndrome in 73.6% of women,resolving within a week.No significant differences were observed between the UAE group and the control group in serum levels of reproductive hormones(FSH,LH,E2,AMH)and ovarian reserve indicators(AFC,OV)at any point up to 36 months post-treatment.Additionally,there were no significant differences in conception,pregnancy,or delivery rates,with the average time to conception and gestational age at delivery being similar between the two groups.Birth weights were also comparable.Finally,there was no significant correlation between ovarian function,fertility indicators,and the type or amount of embolic agent used or the change in fibroids posttreatment.CONCLUSION UAE resulted in significantly positive pregnancy outcomes,no adverse events post-treatment,and is a safe and effective treatment for uterine fibroids that preserves ovarian function and fertility.
文摘Introduction: Uterine leiomyomas, or fibroids, are prevalent benign tumors affecting up to 70% of reproductive-age women in the United States, significantly impacting productivity and quality of life. Despite their commonality, the epidemiology and clinical patterns of leiomyomas in Puerto Rico remain inadequately researched. Methods: This study conducted a secondary data analysis using clinical, menstrual cycle characteristics, and demographic data from self-administered questionnaires of women undergoing diagnostic laparoscopy for endometriosis in Puerto Rico. Chi-square tests and t-tests analyzed categorical and continuous variables, respectively (p Results: Among 1,610 endometriosis cases, 312 included uterine fibroids. Prevalence estimates were 10.3% (40 years). Primiparous women averaged 22.14 years, with 40.71% having 2 - 3 pregnancies and 26.28% experiencing miscarriages. Symptoms included infertility (29.5%), dyspareunia (40.7%), severe pain (50%), and dysmenorrhea (75.6%). Comorbidities included ovarian cysts (52.2%) and abnormal uterine bleeding (37.8%). Conclusions: Advanced age, parity, and comorbidities like diabetes and hypertension were prevalent in our cohort. Understanding the epidemiological profile of women living in Puerto Rico with uterine fibroids is crucial for improving diagnostic awareness and enhancing patient care.
文摘BACKGROUND Microwave endometrial ablation(MEA)is a minimally invasive treatment method for heavy menstrual bleeding.However,additional treatment is often required after recurrence of uterine myomas treated with MEA.Additionally,because this treatment ablates the endometrium,it is not indicated for patients planning to become pregnant.To overcome these issues,we devised a method for ultrasound-guided microwave ablation of uterine myoma feeder vessels.We report three patients successfully treated for heavy menstrual bleeding,secondary to uterine myoma,using our novel method.CASE SUMMARY All patients had a favorable postoperative course,were discharged within 4 h,and experienced no complications.Further,no postoperative recurrence of heavy menstrual bleeding was noted.Our method also reduced the myoma’s maximum diameter.CONCLUSION This method does not ablate the endometrium,suggesting its potential appli-cation in patients planning to become pregnant.

文摘BACKGROUND Currently,the use of dienogest in clinical practice has increased significantly,and many studies have focused on its effectiveness and safety in the treatment of endometriosis and adenomyosis;however,the effects of treatment with dienogest on uterine fibroid size in patients with endometriosis or adenomyosis have not been investigated.AIM To explore changes in fibroid size in patients with concomitant uterine fibroids undergoing dienogest treatment for endometriosis or adenomyosis and to evaluate the effectiveness and safety of the drug.METHODS The clinical data of patients with uterine fibroids treated with dienogest for endometriosis or adenomyosis at Peking University First Hospital from January 2021 to January 2023 were retrospectively analyzed.RESULTS The maximum uterine fibroid diameter and volume increased after 3 months,6 months and 1 year of dienogest treatment compared with those before treatment(P<0.01).The maximum diameter and volume of the uterine adenomyoma increased after 3 months of dienogest treatment but decreased after 6 months and 1 year of treatment compared with those before treatment,but the difference was not significant(P>0.05).Endometrial thickness and antigen 125 levels were significantly thinner and decreased,respectively,after dienogest treatment(P<0.01).Pearson's correlation analysis revealed that the increase in uterine fibroid volume after 3 months of dienogest treatment was positively correlated with the basic uterine fibroid volume(r=0.792,P<0.01).Among 64 patients with dysmenorrhea,63 experienced significant relief of dysmenorrhea after 6 months of treatment with dienogest,and all patients experienced significant relief of dysmenorrhea after 12 months.Patients were able to tolerate the drugs,with an average drug tolerance score of 8.73.CONCLUSION The use of dienogest in patients with endometriosis or adenomyosis combined with uterine fibroids can effectively relieve the patient's pain symptoms and significantly reduce the sizes of ovarian endometriotic cysts,but it cannot inhibit uterine fibroid growth.
