Uterine Myomectomy

子宫肌瘤切除术
  • 文章类型: Journal Article
    背景:子宫平滑肌瘤(通常称为肌瘤或肌瘤)是常见的良性,在子宫中生长的激素依赖性肿瘤,发生在大约25%的育龄妇女中,取决于选定的人口。治疗建议通常基于肌瘤大小,location,病人的年龄,生殖计划,和产科历史。尽管子宫肌瘤及其症状的治疗选择范围广泛,包括子宫切除术,子宫肌瘤切除术,子宫内膜消融,子宫内膜子宫动脉栓塞术,磁共振引导的聚焦超声手术,子宫肌瘤切除术仍然是希望进行子宫肌瘤保留生育能力手术的患者的金标准治疗方法。子宫肌瘤切除术,虽然是切除肌瘤的普遍手术选择,具有已知的风险,如肌瘤复发,症状复发,以及随后重新干预的需要。尽管在肌瘤的医学治疗方面正在进行研究和进步,目前尚无普遍推荐的治疗性干预措施被证明能有效延缓子宫肌瘤的复发或手术后症状的复发.这种情况强调了未满足的医疗需求的重要领域,并强调了继续调查子宫肌瘤切除术患者的预防策略和长期管理选择的重要性。我们设计了一项研究来评估新的FDA批准的GnRH拮抗剂的疗效,Myfembree延迟肌瘤及其相关症状的复发。
    方法:随机,prospective,开放标签临床试验。参与者(n=136)将随机分为两组。对照组(护理标准)将在手术子宫肌瘤切除术后接受标准护理(SoC)治疗,治疗组将在手术子宫肌瘤切除术后接受Relugolix联合治疗(Myfembree®)。研究方案得到芝加哥大学机构审查委员会(IRB#22-0282)的批准。确保所有参与者在加入前提供书面知情同意书。
    结论:在这个项目中,我们建议使用每日剂量的Relugolix联合治疗(Relugolix与雌二醇和醋酸炔诺酮),被批准用于子宫肌瘤治疗,有可能延迟纤维瘤症状的复发,延长保留子宫手术后的生活质量和延迟再干预的需要。
    背景:研究方案于2022年9月16日获得芝加哥大学机构审查委员会的批准,并于2022年9月7日在ClinicalTrials.gov注册,编号NCT05538689。所有受试者将提供参与的知情同意书。
    BACKGROUND: Uterine leiomyomas (often referred to as fibroids or myomas) are common benign, hormone-dependent tumors that grow in the uterus and occur in approximately 25% of reproductive age women, depending on selected population. Treatment recommendation is typically based on fibroid size, location, the patient\'s age, reproductive plans, and obstetrical history. Despite the range of treatment options available for uterine fibroids and their symptoms, including hysterectomy, myomectomy, endometrial ablation, endometrial uterine artery embolization, and magnetic resonance-guided focused-ultrasound surgery, myomectomy remains the gold standard treatment for patients who desire fertility-preserving surgery for their uterine fibroids. Myomectomy, while a prevalent surgical option for the removal of fibroids, carries known risks such as fibroid recurrence, symptom recurrence, and the subsequent need for reintervention. Despite ongoing research and advances in medical treatments for fibroids, there currently are no universally recommended therapeutic interventions proven to effectively delay the recurrence of fibroids or the return of symptoms following this procedure. This situation underscores a significant area of unmet medical need and highlights the importance of continued investigation into preventive strategies and long-term management options for patients undergoing fibroid removal with uterine preservation. We designed a study to assess the efficacy of the new FDA-approved GnRH antagonist, Myfembree in delaying the return of fibroids and their associated symptoms.
    METHODS: A randomized, prospective, open-label clinical trial. The participants (n = 136) will be randomly distributed into two groups. The Control Group (Standard of care) will receive treatment with standard of care (SoC) after surgical myomectomy and the treatment group will receive Relugolix combination therapy (Myfembree®) after surgical myomectomy. The study protocol was approved by the University of Chicago\'s Institutional Review Board (IRB#22-0282), ensuring that all participants would provide written informed consent before their inclusion.
    CONCLUSIONS: In this project, we propose the use of daily dosed Relugolix combination therapy (Relugolix with estradiol and norethindrone acetate), which is approved for uterine fibroids treatment, has the potential to delay the recurrence of fibroid symptoms, prolong the improved quality of life and delay need for re-intervention after uterine sparing surgery.
    BACKGROUND: The study protocol was approved by the Institutional Review Board of the University of Chicago on 9/16/2022 and was registered at ClinicalTrials.gov with number NCT05538689 on Sep 7, 2022. All subjects will provide informed consent to participate.

    子宫肌瘤(平滑肌瘤和肌瘤)是异常子宫出血患者最常见的良性妇科疾病,引起压力或疼痛的盆腔肿块,不孕症和产科并发症。由于症状,几乎三分之一的肌瘤女性需要治疗。
    目的:在这篇综述中,我们介绍了目前所有可用的子宫肌瘤治疗方法。
    方法:广泛搜索有关外科手术的可用数据,进行了子宫肌瘤的医疗和其他治疗选择。
    方法:如今,子宫肌瘤的治疗旨在控制症状,同时保持未来的生育能力。治疗的选择取决于患者的年龄和生育能力和数量,肌瘤的大小和位置。目前的管理策略主要涉及手术干预(子宫切除术和子宫肌瘤切除术,腹腔镜检查或剖腹手术)。其他手术和非手术微创技术包括在放射学或超声引导下进行的干预(子宫动脉栓塞和闭塞,肌溶解,磁共振引导聚焦超声手术,子宫肌瘤射频消融和子宫内膜消融)。子宫肌瘤的医疗选择仍然受到限制,可用的药物(孕激素,联合口服避孕药和促性腺激素释放激素激动剂和拮抗剂)通常用于短期治疗肌瘤引起的出血。最近,研究表明,SPRM可以长期间歇给药,对出血和肌瘤大小减小有良好的效果。新的医学治疗仍在研究中,但取得了有希望的结果。
    结论:肌瘤的治疗必须根据症状的存在和严重程度以及患者对明确治疗或保留生育力的愿望进行个体化治疗。
    Uterine fibroids (leiomyomas and myomas) are the most common benign gynecological condition in patients presenting with abnormal uterine bleeding, pelvic masses causing pressure or pain, infertility and obstetric complications. Almost a third of women with fibroids need treatment due to symptoms.
    OBJECTIVE: In this review we present all currently available treatment modalities for uterine fibroids.
    METHODS: An extensive search for the available data regarding surgical, medical and other treatment options for uterine fibroids was conducted.
    METHODS: Nowadays, treatment for fibroids is intended to control symptoms while preserving future fertility. The choice of treatment depends on the patient\'s age and fertility and the number, size and location of the fibroids. Current management strategies mainly involve surgical interventions (hysterectomy and myomectomy hysteroscopy, laparoscopy or laparotomy). Other surgical and non-surgical minimally invasive techniques include interventions performed under radiologic or ultrasound guidance (uterine artery embolization and occlusion, myolysis, magnetic resonance-guided focused ultrasound surgery, radiofrequency ablation of fibroids and endometrial ablation). Medical treatment options for fibroids are still restricted and available medications (progestogens, combined oral contraceptives andgonadotropin-releasing hormone agonists and antagonists) are generally used for short-term treatment of fibroid-induced bleeding. Recently, it was shown that SPRMs could be administered intermittently long-term with good results on bleeding and fibroid size reduction. Novel medical treatments are still under investigation but with promising results.
    CONCLUSIONS: Treatment of fibroids must be individualized based on the presence and severity of symptoms and the patient\'s desire for definitive treatment or fertility preservation.

    目的:机器人单部位加单孔子宫肌瘤切除术(RSOM)旨在减少切口数量,提高患者的美容满意度,同时保留传统机器人多部位子宫肌瘤切除术(CRM)的优势。相对于传统CRM,机器人单部位加两口子宫肌瘤切除术(RSTM)消除了一个端口,和RSOM相对于RSTM实现了相同的优势。这项研究旨在比较RSOM和RSTM各自的方法和手术结果。
    方法:回顾了230例接受RSOM的患者和146例接受RSTM的患者的医疗记录。使用倾向评分匹配(PSM)分析比较各组的手术结果。
    结果:在总数据中,RSOM的手术时间较短(135.1±57.4minvs.149.9±46.2min,p=0.009)和较短的住院时间(5.2±0.5天vs.5.4±0.7天,p=0.033)相对于RSTM。PSM分析显示,患者基线特征的组间差异无统计学意义。关于手术结果,RSOM组手术时间较短(129.2±49.3minvs.148.7±46.3min,p=0.001)与RSTM组相比。
    结论:与RSTM相比,RSOM与较短的手术时间有关。此外,需要更详细的比较和前瞻性研究来评估RSOM相对于RSTM。
    OBJECTIVE: Robotic single-site plus one-port myomectomy (RSOM) was designed to reduce the number of incision sites for greater cosmetic satisfaction of patients while retaining the benefits of conventional robotic multi-site myomectomy (CRM). Robotic single-site plus two-port myomectomy (RSTM) eliminated one port relative to conventional CRM, and RSOM achieved the same advantage with respect to RSTM. This study aimed to compare RSOM with RSTM in terms of their respective methodologies and surgical outcomes.
    METHODS: The medical records of 230 patients who had undergone RSOM and 146 patients who had undergone RSTM were reviewed. The groups\' surgical outcomes were compared using propensity score matching (PSM) analysis.
    RESULTS: In the total data, RSOM had a shorter operative time (135.1±57.4 min vs. 149.9±46.2 min, p=0.009) and a shorter hospital stay (5.2±0.5 days vs. 5.4±0.7 days, p=0.033) relative to RSTM. The PSM analysis showed that there were no statistically significant intergroup differences in the patients\' baseline characteristics. Regarding the surgical outcomes, the RSOM group showed shorter operative time (129.2±49.3 min vs. 148.7±46.3 min, p=0.001) compared to the RSTM group.
    CONCLUSIONS: Compared with RSTM, RSOM was associated with shorter operative time. Additionally, more detailed comparative and prospective studies are needed to evaluate RSOM relative to RSTM.

    子宫肌瘤,起源于子宫平滑肌细胞的良性肿瘤,患病率因患者种族而异,荷尔蒙暴露,和遗传学。由于其发病率高,这些肿瘤给医疗保健系统带来了巨大的负担。目前的治疗策略从无症状病例的常规监测到有症状患者的子宫肌瘤切除术或子宫切除术等外科手术。随着保留子宫或非手术替代方案的增加趋势。这篇综述研究了现有的子宫肌瘤治疗方法,并探讨了新兴疗法的潜力。根据系统审查的首选报告项目和范围审查的荟萃分析扩展对文献进行范围审查。医学疗法分为激素疗法和非激素疗法;然而,长期的,安全,子宫肌瘤的有效治疗方法有限。除了既定的疗法,研究维生素D或绿茶提取物等物质对子宫肌瘤的影响的研究越来越多。一些研究探讨针灸作为一种可能的替代疗法。虽然现有的治疗方法可以缓解症状并为手术做准备,我们的发现表明,需要进一步研究长期解决方案,特别是由于最近由于肝损害的风险而限制了醋酸乌利司他的使用。涉及维生素D和表没食子儿茶素没食子酸酯的初步研究令人鼓舞;然而,需要更多的研究来确定明确的治疗作用.
    Uterine fibroids, benign tumors originating from uterine smooth muscle cells, vary in prevalence depending on patient ethnicity, hormonal exposure, and genetics. Due to their high incidence, these neoplasms pose a significant burden on healthcare systems. Current treatment strategies range from routine monitoring in asymptomatic cases to surgical procedures such as myomectomy or hysterectomy in symptomatic patients, with an increasing trend toward uterus-preserving or non-surgical alternatives. This review examines the existing medical treatments for uterine fibroids and delves into the potential of emerging therapies. A scoping review of the literature was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Medical therapies are divided into hormonal and non-hormonal treatments; however, long-term, safe, and effective treatments in the treatment of uterine fibroids are limited. In addition to established therapies, there is an increasing number of studies investigating the effect of substances such as vitamin D or green tea extract on uterine fibroids. Some studies investigate acupuncture as a possible alternative therapy. While existing treatments offer symptomatic relief and preparation for surgery, our findings point to a significant need for further research into long-term solutions, especially owing to recent limitations in the use of ulipristal acetate due to risk of liver damage. Initial studies involving vitamin D and epigallocatechin gallate are encouraging; however, additional research is required to establish definitive therapeutic roles.

    背景:口服促性腺激素释放激素拮抗剂relugolix,暂时停止月经,用于治疗大量月经出血,骨盆压力,子宫肌瘤女性的腰背痛。治疗还可以帮助女性从低血红蛋白水平中恢复,并可能缩小肌瘤。然而,腹腔镜子宫肌瘤切除术前使用relugolix的证据有限.然而,治疗可以减少手术间失血,降低术后贫血的风险,缩短手术时间。因此,我们的目的是测试12周术前治疗是否使用relugolix(口服40毫克,每天一次)与亮丙瑞林(每4周注射一次)相似或不差于亮丙瑞林(每4周注射一次),以减少术中失血。
    方法:术前用药的有效性和安全性将在多中心进行研究,随机化,开放标签,平行组,非劣效性试验招募年龄≥20岁的绝经前妇女,诊断为子宫肌瘤,并计划进行腹腔镜子宫肌瘤切除术。参与者(n=80)将在参与机构的临床环境中招募。在1:1分配中使用随机化的最小化方法(预定义的因素:是否存在≥9cm的肌瘤以及国际妇产科联合会[FIGO]1-5型肌瘤)。Relugolix是一种40毫克的口服片剂,每天饭前服用一次,12周,直到手术前一天。亮丙瑞林是1.88毫克,或3.75毫克皮下注射,在手术前患者访视期间间隔3个4周给予。对于术中出血的主要结果测量,从体腔收集血流,手术海绵,和收集袋,以毫升为单位。次要结果指标是血红蛋白水平,肌瘤大小,其他手术结果,和生活质量问卷回答(KuppermanKonenkiShogai指数和子宫肌瘤症状-生活质量)。
    结论:将在临床环境中收集使用口服促性腺激素释放激素拮抗剂的预治疗以减少腹腔镜子宫肌瘤切除术妇女的术中出血的真实世界证据。
    背景:jRCTs031210564于2022年1月19日在日本临床试验注册中心注册(https://jrct。尼夫.走吧。jp)。
    BACKGROUND: The oral gonadotropin-releasing hormone antagonist relugolix, which temporarily stops menstruation, is used to treat heavy menstrual bleeding, pelvic pressure, and low back pain in women with uterine fibroids. Treatment can also help women recover from low hemoglobin levels and possibly shrink the fibroids. However, evidence of preoperative use of relugolix before laparoscopic myomectomy is limited. Nevertheless, the treatment could reduce interoperative blood loss, decrease the risk of developing postoperative anemia, and shorten the operative time. Thus, we aim to test whether 12-week preoperative treatment with relugolix (40 mg orally, once daily) is similar to or not worse than leuprorelin (one injection every 4 weeks) to reduce intraoperative blood loss.
    METHODS: Efficacy and safety of preoperative administration of drugs will be studied in a multi-center, randomized, open-label, parallel-group, noninferiority trial enrolling premenopausal women ≥ 20 years of age, diagnosed with uterine fibroids and scheduled for laparoscopic myomectomy. Participants (n = 80) will be recruited in the clinical setting of participating institutions. The minimization method (predefined factors: presence or absence of fibroids ≥ 9 cm and the International Federation of Gynecology and Obstetrics [FIGO] type 1-5 fibroids) with randomization is used in a 1:1 allocation. Relugolix is a 40-mg oral tablet taken once a day before a meal, for 12 weeks, up to the day before surgery. Leuprorelin is a 1.88 mg, or 3.75 mg subcutaneous injection, given in three 4-week intervals during patient visits before the surgery. For the primary outcome measure of intraoperative bleeding, the blood flow is collected from the body cavity, surgical sponges, and collection bag and measured in milliliters. Secondary outcome measures are hemoglobin levels, myoma size, other surgical outcomes, and quality-of-life questionnaire responses (Kupperman Konenki Shogai Index and Uterine Fibroid Symptoms-Quality of Life).
    CONCLUSIONS: Real-world evidence will be collected in a clinical setting to use pre-treatment with an oral gonadotropin-releasing hormone antagonist to reduce intraoperative bleeding in women who undergo laparoscopic myomectomy.
    BACKGROUND: jRCTs031210564 was registered on 19 January 2022 in the Japan Registry of Clinical Trials ( https://jrct.niph.go.jp ).

    多达70-80%的育龄妇女可能会受到最常见的子宫肿瘤的影响,被称为肌瘤或肌瘤。这些良性肿瘤是绝经前妇女手术的第二大常见原因。预测表明,在怀孕期间肌瘤的发生会增加,怀孕期间患肌瘤的风险随着孕妇年龄的增长而增加。虽然大多数患有子宫肌瘤的女性在怀孕期间没有任何症状,高达30%的女性在怀孕期间遇到问题,分娩,还有产褥期.剖宫产手术(CS)期间肌瘤切除术的可行性是一个有争议的问题,这是由于妊娠中肌瘤的发生率和CS发生率上升而引起的。一种采用经子宫内膜入路切除子宫肌瘤的新手术方法,这包括切开蜕膜本身,对通过浆膜途径进行剖宫产子宫肌瘤切除术(CM)的长期做法表示怀疑。一些作者最近提倡这种最后的方法,强调其在现实世界中的优势和潜在用途。本文的目的是通过分析两种方法之间的临床和手术区别来批评目前的剖宫产子宫肌瘤切除术方法,并提供CM方法的说明。
    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.

    子宫肌瘤是在有生育能力的妇女中发现的常见良性肿瘤。许多产科问题,如分娩时难产,胎儿肥大,羊膜囊破裂,早产,低出生体重新生儿,等。,与纤维状妊娠子宫有关。剖宫产子宫肌瘤切除术不是常见的手术,因为产后子宫切除术的可能性或潜在的致命出血。对于选择的主题,我们介绍了剖宫产子宫肌瘤切除术后紧急产后子宫切除术的两种情况。剖宫产子宫肌瘤切除术后,两名妇女经历了围手术期出血,需要进行产后子宫切除术而不进行输卵管卵巢切除术.由于剖宫产子宫肌瘤切除术后其他止血技术无法控制出血,因此在每种情况下都需要进行产后子宫切除术。在任何情况下,子宫肌瘤的位置和数量,而非大小,是导致产后子宫切除术的主要因素.为了确保病人安全,利大于弊,剖宫产子宫肌瘤切除术的当前趋势包括旨在选择性或在提供机会时进行手术。治疗仍有争议,因为尚不清楚第二次子宫切除术对剖宫产子宫肌瘤切除术的患者有多危险。
    Uterine fibroids are common benign tumors found in fertile women. Numerous obstetrical issues, such as dystocia during labor, fetal hypotrophy, a ruptured amniotic sac, early labor, low-birth-weight newborns, etc., are associated with fibrous pregnant uteri. Cesarean myomectomy is not a common procedure because of the possibility of postpartum hysterectomy or a potentially lethal hemorrhage. For the chosen topic, we present two instances of emergency postpartum hysterectomies following cesarean myomectomy. After a cesarean myomectomy, two women experienced a perioperative hemorrhage that required a postpartum hysterectomy without a salpingo-oophorectomy. A postpartum hysterectomy was required in every instance due to the failure of additional hemostatic techniques to control the bleeding after the cesarean myomectomy. In every case, the location and number of fibroids-rather than their size-were the primary factors leading to the postpartum hysterectomy. In order to ensure that the patient is safe and that the advantages outweigh the dangers, the current trends in cesarean myomectomy include aiming to conduct the procedure either electively or when it offers an opportunity. The treatment is still up for debate because it is unknown how dangerous a second hysterectomy is for people who have had a cesarean myomectomy.

    背景:本研究旨在比较两种新的机器人单部位子宫肌瘤切除术(RSSM)-互补技术的手术结果:同轴机器人单部位子宫肌瘤切除术(同轴-RSSM)和混合机器人单部位子宫肌瘤切除术(Hybrid-RSSM)。
    方法:132名接受同轴RSSM和150名接受混合RSSM的妇女的医疗记录,连续,进行回顾性审查。在倾向评分匹配(PSM)后评估并比较患者特征和手术结果。
    结果:在PSM的结果中,同轴-RSSM组显着减少失血(79.71vs.163.75mL,p<0.001)和缩短住院时间(4.18±0.62vs.4.63±0.90)相对于Hybrid-RSSM组。相反,与同轴RSSM相比,混合RSSM允许更短的手术时间(119.19vs.156.01min,p=0.007)。两组均未转换为传统的腹腔镜检查或剖腹手术,也未需要多部位机器人方法。术后并发症,包括肠梗阻,发烧,伤口裂开,两组间差异无统计学意义。
    结论:同轴RSSM的失血量较低,Hybrid-RSSM手术时间较短。为了更全面地比较两种技术之间的手术结果,需要进行随访前瞻性研究。
    BACKGROUND: This study aimed to compare surgical outcomes between two new robotic single-site myomectomy (RSSM)-complementary techniques: coaxial robotic single-site myomectomy (Coaxial-RSSM) and hybrid robotic single-site myomectomy (Hybrid-RSSM).
    METHODS: Medical records for 132 women undergoing Coaxial-RSSM and 150 undergoing Hybrid-RSSM, consecutively, were retrospectively reviewed. Patient characteristics and surgical outcomes were assessed and compared after propensity score matching (PSM).
    RESULTS: In the outcomes of PSM, the Coaxial-RSSM group showed significantly reduced blood loss (79.71 vs. 163.75 mL, p < 0.001) and reduced hospital duration (4.18 ± 0.62 vs. 4.63 ± 0.90) relative to the Hybrid-RSSM group. Conversely, Hybrid-RSSM allowed for a shorter operative time compared with Coaxial-RSSM (119.19 vs. 156.01 min, p = 0.007). No conversions to conventional laparoscopy or laparotomy or any need for the multi-site robotic approach occurred in either group. Postoperative complications, including ileus, fever, and wound dehiscence, showed no statistically significant differences between the two groups.
    CONCLUSIONS: Blood loss was lower with Coaxial-RSSM, and operative time was shorter for Hybrid-RSSM. A follow-up prospective study is warranted for more comprehensive comparison of surgical outcomes between the two techniques.

    背景:本研究旨在确定腹腔镜子宫肌瘤切除术中尼卡地平治疗垂体后叶素诱发的高血压的中位有效剂量(ED50)和95%有效剂量(ED95)。为此类患者的术中血压管理提供指导。
    方法:在最初的40名参与者中,24例行择期腹腔镜子宫肌瘤切除术。根据尼卡地平的抗高血压功效,采用顺序上下方法确定尼卡地平的ED50。在第一例患者诊断为垂体后叶素诱导的高血压后,最初以6µg/kg的剂量施用尼卡地平。进行剂量调整以达到预期的抗高血压效果,在120s内将收缩压和心率恢复到基线的±20%以内。对于有效或无效的反应,剂量增加或减少设定为0.5µg/kg,分别。通过最大似然估计(MLE)使用Probit回归计算尼卡地平的ED50和ED95,以建立剂量反应曲线和置信区间。
    结果:最终纳入24例患者进行分析。测定尼卡地平注射垂体后叶素后控制血压的ED50和ED95。研究发现,尼卡地平治疗垂体后叶素诱发的高血压的ED50为4.839µg/kg(95%CI:4.569-5.099µg/kg),ED95估计为5.308µg/kg(95%CI:5.065-6.496µg/kg)。尼卡地平可有效缓解垂体后叶素引起的高血压反应,而不会引起明显的心动过速或低血压。
    结论:在腹腔镜子宫肌瘤剔除术中注射垂体后叶素后,尼卡地平能有效控制血压,建立ED50和ED95值。这项研究强调了尼卡地平在解决垂体后叶素引起的高血压反应中的潜在用途。特别是在常规使用垂体后叶素的临床环境中。
    BACKGROUND: This study aimed to determine the median effective dose (ED50) and 95% effective dose (ED95) of nicardipine for treating pituitrin-induced hypertension during laparoscopic myomectomy, providing guidance for the management of intraoperative blood pressure in such patients.
    METHODS: Among the initial 40 participants assessed, 24 underwent elective laparoscopic myomectomy. A sequential up-and-down method was employed to ascertain the ED50 of nicardipine based on its antihypertensive efficacy. Nicardipine was initially administered at 6 µg/kg following the diagnosis of pituitrin-induced hypertension in the first patient. Dosing adjustments were made to achieve the desired antihypertensive effect, restoring systolic blood pressure and heart rate to within ± 20% of baseline within 120 s. The dosing increment or reduction was set at 0.5 µg/kg for effective or ineffective responses, respectively. The ED50 and ED95 of nicardipine were calculated using Probit regression by Maximum Likelihood Estimation (MLE) to establish dose-response curves and confidence intervals.
    RESULTS: 24 patients were included for analysis finally. The ED50 and ED95 of nicardipine for blood pressure control after pituitrin injection were determined. The study found that the ED50 of nicardipine for treating pituitrin-induced hypertension was 4.839 µg/kg (95% CI: 4.569-5.099 µg/kg), and the ED95 was estimated at 5.308 µg/kg (95% CI: 5.065-6.496 µg/kg). Nicardipine effectively mitigated the hypertensive response caused by pituitrin without inducing significant tachycardia or hypotension.
    CONCLUSIONS: Nicardipine effectively controlled blood pressure after pituitrin injection during laparoscopic myomectomy, with ED50 and ED95 values established. This research highlights the potential utility of nicardipine in addressing hypertensive responses induced by pituitrin, particularly in clinical settings where pituitrin is routinely administered.

    结果:中位随访时间为3.8年(四分位距1.8-7.4年)。指数程序为18.0%(1,857)宫腔镜子宫肌瘤切除术,16.2%(1669)子宫动脉栓塞,21.4%(2,211)子宫内膜消融,和44.4%(4,587)的子宫肌瘤切除术。审查会计,子宫肌瘤切除术的7年再干预风险为20.6%,子宫动脉栓塞术占26.0%,子宫内膜消融术占35.5%,宫腔镜子宫肌瘤剔除术占37.0%;再次干预的63.2%为子宫切除术。在每种程序类型中,再干预率不因BMI而异,种族和民族,或者邻里剥夺指数.然而,子宫动脉栓塞后的再干预率,子宫内膜消融,宫腔镜子宫肌瘤切除术随着年龄的增长而减少,宫腔镜下子宫肌瘤切除术的再干预率高于未产妇。
    结论:子宫动脉栓塞的长期再干预风险,子宫内膜消融,宫腔镜子宫肌瘤切除术比子宫肌瘤切除术要多,随着患者年龄和胎次的潜在变化,而不是BMI,种族和民族,或者邻里剥夺指数.
    OBJECTIVE: To compare long-term risk of reintervention across four uterus-preserving surgical treatments for leiomyomas and to assess effect modification by sociodemographic factors in a prospective cohort study in an integrated health care delivery system.
    METHODS: We studied a cohort of 10,324 patients aged 18-50 (19.9% Asian, 21.2% Black, 21.3% Hispanic, 32.5% White, 5.2% additional races and ethnicities) who had a first uterus-preserving procedure (abdominal, laparoscopic, or vaginal myomectomy [referred to as myomectomy]; hysteroscopic myomectomy; endometrial ablation; uterine artery embolization) after leiomyoma diagnosis in the 2009-2021 electronic health records of Kaiser Permanente Northern California. We followed up patients until reintervention (second uterus-preserving procedure or hysterectomy) or censoring. We used a Kaplan-Meier estimator to calculate the cumulative incidence of reintervention and Cox regression models to estimate hazard ratios and 95% CIs comparing rates of reintervention across procedures, adjusting for age, parity, race and ethnicity, body mass index (BMI), Neighborhood Deprivation Index, and year. We also assessed effect modification by demographic characteristics.
    RESULTS: Median follow-up was 3.8 years (interquartile range 1.8-7.4 years). Index procedures were 18.0% (1,857) hysteroscopic myomectomies, 16.2% (1,669) uterine artery embolizations, 21.4% (2,211) endometrial ablations, and 44.4% (4,587) myomectomies. Accounting for censoring, the 7-year reintervention risk was 20.6% for myomectomy, 26.0% for uterine artery embolization, 35.5% for endometrial ablation, and 37.0% for hysteroscopic myomectomy; 63.2% of reinterventions were hysterectomies. Within each procedure type, reintervention rates did not vary by BMI, race and ethnicity, or Neighborhood Deprivation Index. However, rates of reintervention after uterine artery embolization, endometrial ablation, and hysteroscopic myomectomy decreased with age, and reintervention rates for hysteroscopic myomectomy were higher for parous than nulliparous patients.
    CONCLUSIONS: Long-term reintervention risks for uterine artery embolization, endometrial ablation, and hysteroscopic myomectomy are greater than for myomectomy, with potential variation by patient age and parity but not BMI, race and ethnicity, or Neighborhood Deprivation Index.
