Endometrial ablation

Endometrial cancer is the most common gynecologic malignancy. PTEN is a negative regulator of PI3K signaling and is deficient in > 50% of primary human endometrial cancer. Amplification of ERBB2 promotes tumorigenesis and pathogenesis of several human cancers. However, the effect of ERBB2 targeting has not been studied in endometrial cancer with PTEN mutations. The murine model Pgrcre/+ Erbb2f/f Ptenf/f (Erbb2d/d Ptend/d ) was developed to evaluate the effect of ERBB2 targeted therapy in endometrial cancer with PTEN deficiency...

INTRODUCTION: Many women experience bleeding disorders that may have an anatomical or unexplained origin. Although hysterectomy is the most definitive and common treatment, it is highly invasive and resource-intensive. Less invasive therapies are therefore advised before hysterectomy for women with fibroids or bleeding disorders. This study has two aims related to treating bleeding disorders and uterine fibroids in the Netherlands: (1) to evaluate the regional variations in prevalence and surgical approaches; and (2) to assess the associations between regional rates of hysterectomies and less invasive surgical techniques to analyze whether hysterectomy can be replaced in routine practice...

BACKGROUND Endometriosis is a common cause of chronic pelvic pain among women globally. Pharmacological therapy for endometriosis includes non-steroidal anti-inflammatory drugs (NSAIDs) and hormonal contraceptives, while surgical therapy often involves either laparoscopic excision and ablation of endometriosis implants or open surgery. Surgical therapy is one of the mainstays of treatment especially for extrapelvic endometriomas. However, little guidance exists for the treatment of non-palpable or intermittently palpable lesions of this nature...

RATIONALE: Hysterectomy after microwave ablation (MWA) is more difficult than conventional surgery which increases the probability of postoperative complications due to MWA's collateral thermal damage to nearby intestines. Here we report a case of multiple postoperative complications after hysterectomy following MWA. PATIENT CONCERNS: A 44-year-old female was admitted due to progressive abdominal pain during menstruation for 30 years and no relief 1 year after MWA...

OBJECTIVE: The present study aimed to investigate the clinical efficacy of endometrial ablation with high-intensity focused ultrasound (HIFU) for symptom relief in women with adenomyosis. METHODS: Between July 2014 and July 2020, 167 patients with adenomyosis treated at the Zhongshan City People's Hospital were enrolled in this study. Patients were divided into two groups according to patient aspirations: the control group, including patients who only underwent ablation of adenomyosis lesions (group A) and the treatment group, including patients who underwent removal of adenomyosis lesions and endometrial ablation (group B)...

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...

Using an established human primary cell culture model, we previously demonstrated that the promyelocytic leukemia zinc finger (PLZF) transcription factor is a direct target of the progesterone receptor (PGR) and is essential for progestin-dependent decidualization of human endometrial stromal cells (HESCs). These in vitro findings were supported by immunohistochemical analysis of human endometrial tissue biopsies, which showed that the strongest immunoreactivity for endometrial PLZF is detected during the progesterone (P4)-dominant secretory phase of the menstrual cycle...

Rupture of a gravid uterus is a known complication of a cesarean hysterotomy. Uterine rupture of a nongravid uterus is usually caused by trauma, instrumentation, a pelvic mass, infection, or malignancy. Spontaneous rupture of a nongravid uterus is a rare event with only 4 cases reported in the English literature since 2011. This was the case of a healthy 52-year-old woman with a remote history of 2 cesarean deliveries and an endometrial ablation. The patient presented with severe right lower-quadrant pain. The hospital evaluation revealed a hemoperitoneum, a 5 cm endometrial complex or mass, and layering of blood product along the cesarean delivery scar...

INTRODUCTION: Treatment of recurrent oligometastatic gynecologic malignancy may involve targeted surgery, thermal ablation, or CT-guided high-dose-rate interstitial brachytherapy ablation (CT-HDR-IBTA). The purpose of this study was to describe the safety and efficacy of CT-HDR-IBTA for oligometastatic gynecologic malignancies. METHODS: With institutional review board approval (IRB) approval and compliance with the Health Insurance Portability and Accountability Act of 1996 (HIPAA) compliance, we searched our database to assemble a single-arm study cohort of all patients with oligometastatic gynecologic cancers who underwent CT-HDR-IBTA from 2012-2022 with follow-up...

Uterine leiomyomas, also known as fibroids or myomas, occur in an estimated 70-80% of reproductive aged women. Many experience debilitating symptoms including pelvic pain, abnormal uterine bleeding (AUB), dyspareunia, dysmenorrhea, and infertility. Current treatment options are limited in preserving fertility, with many opting for sterilizing hysterectomy as a form of treatment. Currently, surgical interventions include hysterectomy, myomectomy, and uterine artery embolization in addition to endometrial ablation to control AUB...

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...

Abnormal uterine bleeding is a frequent symptom in the perimenopause. Causes are numerous, ranging from physiological reactions due to decreasing/unstable ovarian function to premalignant and malignant conditions. Benign findings such as endometrial polyps and myomas increase with age, leading to more abnormal uterine bleeding in the perimenopause. Cervical and vaginal causes of abnormal uterine bleeding should be excluded by speculum examination. Sexually transmitted diseases or pregnancy should be ruled out...

Endometrial cancer (EC) is the most common gynecologic malignancy. While the majority of patients present with early-stage and low-grade EC and have an excellent prognosis, a subset has metastatic disease at presentation or develops distant recurrence after initial treatment of the primary. However, the lack of prognostic biomarkers for metastatic EC is a critical barrier. Arginase 1 (ARG1) regulates the last step of the urea cycle, and an increase in ARG1 has been correlated as a poor prognostic factor in a variety of cancers...

OBJECTIVE: To describe the ultrasonographic appearance of the post-ablative endometrium to improve knowledge of its sonographic findings. METHODS: This was an Institutional Review Board approved prospective study of patients who underwent second-generation endometrial ablation from 2016 to 2019 at a single health system. Patients had postoperative transvaginal ultrasounds at 2, 6, and 12 months. Ultrasound reports were analyzed for endometrial thickness, description of the endometrium and myometrium, presence of uterine fibroids, and uterine size...

Heterotopic triplet pregnancy, cesarean scar ectopic pregnancy, and pregnancy following uterine ablation are all rare events that confer significant morbidity including spontaneous abortion, intrauterine fetal demise, preterm labor, abnormal placentation, and uterine rupture. A woman in her 30s, G6P4014, with a history of uterine ablation presented with delayed menses and vaginal spotting with imaging showing two intrauterine pregnancies (one with cardiac activity) and one live pregnancy at the cesarean scar...

Intrauterine adhesion (IUA) stands as a prevalent medical condition characterized by endometrial fibrosis and scar tissue formation within the uterine cavity, resulting in infertility and, in severe cases, recurrent miscarriages. Cell therapy, especially with stem cells, offers an alternative to surgery, but concerns about uncontrolled differentiation and tumorigenicity limit its use. Exosomes, more stable and immunogenicity-reduced than parent cells, have emerged as a promising avenue for IUA treatment. In this study, a novel approach has been proposed wherein exosomes originating from decidual stromal cells are encapsulated within sodium alginate hydrogel (SAH) scaffolds to repair endometrial damage and restore fertility in a mouse IUA model...

BACKGROUND: The symptom of heavy menstrual bleeding has a significant impact on professional, physical and social functioning. In 2021, results from a randomized controlled trial comparing a 52 mg levonorgestrel-releasing intrauterine system and radiofrequency non-resectoscopic endometrial ablation as treatments for women with heavy menstrual bleeding were published. Both treatment strategies were equally effective in treating heavy menstrual bleeding during a two-year follow-up. However, long-term results are also relevant for both patients and health care providers...

BACKGROUND: The procedure for microwave endometrial ablation (MEA) follows established MEA practice guidelines but requires hysteroscopic observation of the uterine lumen before and after MEA. When a luminal uterine lesion is recognized, its removal requires preoperative dilation of the cervix because the outer diameter of a conventional rigid hysteroscope is 8.7 mm. Recently, a fully disposable rigid hysteroscope (LiNA OperaScopeTM ) with a narrow diameter (4.4 mm) and forceps capable of extracting endometrial lesions has become available...

BACKGROUND AIMS: Chronic allograft vasculopathy (CAV) remains a predominant contributor to late allograft failure after organ transplantation. Several factors have already been shown to facilitate the progression of CAV, and there is still an urgent need for effective and specific therapeutic approaches to inhibit CAV. Human mesenchymal-like endometrial regenerative cells (ERCs) are free from the deficiencies of traditional invasive acquisition methods and possess many advantages. Nevertheless, the exact immunomodulation mechanism of ERCs remains to be elucidated...

BACKGROUND: Heavy menstrual bleeding is a common problem that can significantly affect women's lives until menopause. There is a lack of evidence on longer-term outcomes after seeking health care and treatment for heavy menstrual bleeding. OBJECTIVES: To assess the continuation rates of medical treatments and the rates of ablative and surgical interventions among women who had participated in the ECLIPSE trial (ISRCTN86566246) 10 years after initial management for heavy menstrual bleeding in primary care...
