Uterine leiomyoma is associated with the risk of developing endometriosis: A nationwide cohort study involving 156,195 women

Similar but Distinct Comorbidity Patterns Between Polycystic Ovary Syndrome and Endometriosis in Korean Women: A Nationwide Cohort Study

BACKGROUND

Polycystic ovary syndrome (PCOS) and endometriosis are widely recognized as significant risk factors affecting the reproductive health of women. The underlying mechanisms impacting fertility may vary, potentially leading to divergent outcomes. We aimed to examine and contrast the prevalence patterns of diseases coexisting with PCOS and endometriosis, using a large-scale nationwide insurance claims data from Asian women of reproductive age.

METHODS

We analyzed health insurance and examination data of 157,662 Korean women aged 15-45 years, drawn from the Korea National Health Insurance Service-National Sample Cohort database. International Classification of Disease, Tenth Revision codes were mapped to phenome-wide association study codes (phecodes). Subsequently, multivariate logistic regression was performed to assess the comorbidity patterns among patients diagnosed with PCOS and endometriosis and healthy control groups.

RESULTS

Our analysis revealed that PCOS was correlated with a wider range of metabolic disorders and symptoms, such as hyperlipidemia, type 2 diabetes, various gastrointestinal (GI) issues, and an array of pregnancy-related complications. Conversely, endometriosis was more prevalent among benign neoplasms of female reproductive and digestive organs, endometrial hyperplasia, and angina pectoris. Notably, infertility and glaucoma demonstrated significant associations with both conditions. Furthermore, a comparison of symptom-related codes in women with endometriosis revealed a predominance of pain-related symptoms, whereas those with PCOS exhibited a broader spectrum, encompassing pain, pruritus, GI problems, cough, fever, menstrual cycle disorders, edema, and dizziness.

CONCLUSION

PCOS and endometriosis, which are prevalent gynecological disorders affecting similar age groups of women, rarely co-occur and exhibit unique comorbidity profiles. Tailored healthcare strategies that take into account these distinct patterns have the potential to enhance long-term healthcare outcomes of affected patients. Further research is required to elucidate the underlying mechanisms and contrasting comorbidity profiles between PCOS and endometriosis.

Ultrasound-guided microwave, radiofrequency, and high intensity focused ultrasound (HIFU) ablation in treating uterine leiomyoma: A systemic review and meta-analysis of retrospective studies

To retrospectively evaluate the efficacy and safety of ultrasound-guided microwave (MWA), radiofrequency (RF), and high-intensity focused ultrasound (HIFU) ablation in the treatment of uterine leiomyoma and to provide a suggestion for the selection of clinical treatment of uterine leiomyoma. The retrospective cohort studies on the efficacy of high-intensity focused ultrasound in treating uterine leiomyoma was collected through a literature search in Pubmed, Embase, Cochrane library, Scopus, and Web of Science, and selected according to the specified inclusion criteria and exclusion criteria. Evaluate the study quality, extract relevant data, and RevMan 5.4.1 was used to conduct this meta-analysis. Compared with HIFU therapy, the complete or partial ablation rate and recurrence rate of uterine leiomyoma treated with RFA/MWA were statistically different (P < 0.05). Compared with RF, the overall efficacy of HIFU in treating uterine leiomyoma was not as good as that of RF. There was no significant difference between the RFA therapy and the MWA. HIFU still has mild and short-term complications, such as abdominal pain, bloody vaginal discharge, sacral pain, and fever. Although myomectomy is usually the first choice for uterine preservation, RFA/MWA and HIFU have also been shown to relieve clinical symptoms significantly, shorten treatment time, reduce complications, and improve prognosis.

Myomectomy: Choosing the Surgical Approach - A Systematic Review

Myomectomy has evolved from open laparotomy to laparoscopy, hysteroscopy, VNOTES and robotic myomectomy. The surgical approach in doing myomectomy depends on the type and location of the myoma and the surgeon's expertise. Minimally invasive surgery has been the preferred approach due to the benefit of shorter hospital stay, lesser postoperative pain, earlier recovery, minimal blood loss and the cosmetic appearance of the scar. The success of this procedure depends on the incision technique, enucleation, and blood loss prevention by using hemostatic techniques and suturing techniques. Performing myomectomy for a large uterine myoma is a laparoscopic challenge; however, with the use of Lee-Huang point (midpoint between umbilicus and xiphoid) as the primary insertion and camera port, one can easily navigate thru the abdominal cavity in case the uterus is huge obscuring the umbilical port. Laparoscopic Myomectomy can be safely and efficiently performed by experienced laparoscopic surgeons regardless of myoma size, number and location. Removal of large myoma specimen from the abdominal cavity through the laparoscope became a challenge after the use of power morcellator was abandoned. To overcome this problem, the large myoma is placed inside an Endo bag and its edges brought extracorporeally through the port site. The myoma is incised in a C-manner using a scalpel to reduce the size. Myoma can also be removed using in-bag power morcellation. Fertility preservation is the long-term aim of doing myomectomy instead of hysterectomy in the management of leiomyoma aside from alleviating symptoms of abnormal uterine bleeding, urinary frequency and abdominal pain.

Use of the Free Endometriosis Risk Advisor App as a Non-Invasive Screening Test for Endometriosis in Patients with Chronic Pelvic Pain and/or Unexplained Infertility

Endometriosis is a prevalent condition that affects millions of individuals globally, leading to various symptoms and significant disruptions to their quality of life. However, the diagnosis of endometriosis often encounters delays, emphasizing the pressing need for non-invasive screening. This retrospective cross-sectional study aimed to evaluate the utility of the Endometriosis Risk Advisor (EndoRA) mobile application in screening for endometriosis in patients with chronic pelvic pain and/or unexplained infertility. The study consisted of 293 patients who met specific criteria: they were English-speaking individuals with chronic pelvic pain and/or unexplained infertility, owned smartphones, and had no prior diagnosis of endometriosis. The results demonstrated that the EndoRA score exhibited a high sensitivity of 93.1% but a low specificity of 5.9% in detecting endometriosis. The positive predictive value was 94.1%, while the negative predictive value was 5.0%. Although the study had limitations and potential selection bias, its findings suggest that EndoRA can serve as a valuable screening tool for high-risk individuals, enabling them to identify themselves as being at an increased risk for endometriosis. EndoRA's non-invasive nature, free access, and easy accessibility have the potential to streamline evaluation and treatment processes, thereby empowering individuals to seek timely care and ultimately improving patient outcomes and overall well-being.

Cystic endometriosis in a degenerated sub-serous myoma in a sub-fertile woman: A case report

INTRODUCTION AND IMPORTANCE

Leiomyoma is the most common gynecologic tumor which may show atypical locations and degenerations. Cystic degeneration is said to be found in 4 % of all degenerations. Endometriosis, the presence of endometrial glands and stroma at extrauterine sites, is a common gynaecological condition seen in 10 % to 15 % of reproductive-age women usually being associated with various degrees of fertility problems.

CASE PRESENTATION

40 years old woman with P1L1A2, with secondary sub-fertility for 5 years, presented with chief complaints of dysmenorrhoea for 1 year initially around the menstrual cycle relieving with analgesics but later not limited to the menstrual cycle and pain not relieving with analgesics since 1 month. The patient underwent fertility-sparing laparoscopic removal avoiding a laparotomy and definitive hysterectomy. Manual morcellation was achieved.

CLINICAL DISCUSSION

Cystic degeneration is rare in Leiomyoma although it is the more common gynaecological tumor in women and is associated with endometriosis probably due to retrograde menstruation.

CONCLUSIONS

Laparoscopic removal of leiomyoma without laparotomy and definitive hysterectomy for a case of cystic endometriosis in a degenerated subserous myoma which to the best of our knowledge according to our search of articles on the relevant topic is the first reported case pertaining to the topic from Nepal.

The environmental risk factors related to uterine leiomyoma: An umbrella review

BACKGROUND

Uterine leiomyoma (UL) is the most common benign tumor of the reproductive period and become a major health problem. The present umbrella review assessed the environmental risk factors associated with UL based on meta-analyses studies.

MATERIALS AND METHODS

We searched three Major databases until February 2022. The meta-analyses that had focused on evaluating the environmental risk factors associated with the UL were included. The summary effect estimates, 95% CI, heterogeneity I², 95% prediction interval, small-study effects, excess significance biases, and sensitive analysis were applied. We used A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2) for assessing the quality of the meta-analyses.

RESULT

The risk factor of chronic psychological stress (OR 1.24, 95% CI: 1.15, 1.34) and obesity (OR 1.19, 95% CI: 1.09, 1.29) was graded as suggestive evidence (class III). The current alcohol intake (OR 1.33, 95% CI: 1.01, 1.76) was graded as the risk factor with weak evidence (class IV). Current oral contraceptive (OCP) use (RR 0.43, 95% CI: 0.25, 0.73) (class IV), and former smokers (OR 0.93, 95% CI: 0.88, 0.99) (class IV) were as the protective factors.

CONCLUSION

The current alcohol intake, chronic psychological stress, and obesity were risk factors for the UL, but current OCP use and former smokers were the protective factors.

A Case Report of Non-puerperal Uterine Inversion due to Submucosa Leiomyoma in a Young Virgin Woman

The inversion of the uterus is a rare complication of the puerperium and much rarer during the non-puerperal period. The most common cause of non-puerperal inversion is a submucosa leiomyoma; however, identification can be difficult. Herein, we present a case of pedunculated uterine leiomyoma that causes uterus inversion in a 30-year-old virgin woman with a correct diagnosis; a hysterectomy was prevented for the patient.

Endometriosis and irritable bowel syndrome: similarities and differences in the spectrum of comorbidities

STUDY QUESTION

Do the spectrum and prevalence of comorbidities of endometriosis and irritable bowel syndrome (IBS) overlap?

SUMMARY ANSWER

Despite several overlapping symptoms, the most significantly associated comorbidities of endometriosis and IBS are different and are rather related to the organ systems primarily involved in the index diagnosis.

WHAT IS KNOWN ALREADY

Endometriosis and IBS both have several similar unspecific symptoms, such as recurrent abdominal pain, cramping and anxiety, and both diseases affect young women and are associated with a number of comorbidities causing a poor quality of life. However, a detailed study, revealing the full spectrum of endometriosis and IBS comorbidities in the same study population, is lacking.

STUDY DESIGN, SIZE, DURATION

This article presents a retrospective in silico analysis of the data from a large nationwide biobank-based cohort consisting of 121 773 women. After excluding all first- and second-degree relatives, the data of up to 65 421 women were analyzed.

PARTICIPANTS/MATERIALS, SETTING, METHODS

International Classification of Disease-10 diagnosis main codes associated with endometriosis (N80) and IBS (K58) diagnoses were identified from the Estonian Biobank dataset by linking with the Estonian Health Insurance Fund and other relevant registries. The associations between N80 and K58 and other diagnosis codes were tested using logistic regression, adjusting for age at recruitment and 10 genetic principal components to account for potential population stratification. Bonferroni correction was applied to account for multiple testing.

MAIN RESULTS AND THE ROLE OF CHANCE

Both women with endometriosis and IBS suffered from more conditions compared to the control group, with 226 and 428 diagnosis codes statistically significantly more frequent in women with respective diagnosis compared to controls. Women suffering from both conditions had 275 significantly associated comorbidities. A remarkable proportion of women with IBS or endometriosis suffered also from endometriosis (9.0%) or IBS (13.6%), respectively. In endometriosis, the most prevalent diagnoses were related to diseases of the genitourinary system (33 N-category codes) and in women with IBS, the most associated diagnoses were related to digestive disorders and gastrointestinal tract (52 codes from K-category). Among the most significant diagnoses in endometriosis were uterine leiomyomas (D25), menstrual disorders (N92) and infertility (N97) (P < 1 × 10-315 for all), and in IBS, lactose intolerance (E73), gastritis and duodenitis (K29) and functional dyspepsia (K30) were in the top list of most significant comorbidities (P < 1 × 10-315 for all).

LIMITATIONS, REASONS FOR CAUTION

The information about the severity stages of endometriosis and subtypes of IBS was not available for analysis. The findings may not be fully extrapolated to all female populations, because all participants were from one geographic area and had good access to health services.

WIDER IMPLICATIONS OF THE FINDINGS

These findings support previous studies that have found a high prevalence of pre-selected comorbidities in women with endometriosis and IBS. However, taking into account the differences in the full spectrum of comorbidities of endometriosis and IBS may aid in diagnosing these disorders. Women and healthcare providers need to be aware that women with endometriosis are at high risks of complications during pregnancy and should be carefully monitored.

Successful Laparoscopic-Assisted Supracervical Hysterectomy in a 14-Week-Sized Fibroid Uterus: An Autobiographical Case Report

Uterine leiomyomas are a very common gynecological condition. This case report describes the author’s experience pursuing definitive treatment of a 14-week-sized fibroid uterus, the associated menometrorrhagia, and bulk symptoms. Barriers still remain if women of reproductive age prefer ovary-sparing hysterectomy. Laparoscopic supracervical hysterectomy with contained morcellation remains a well-tolerated and low-risk option dependent on surgeon expertise and informed patient consent. Literature review reveals the psychosocial and financial burden of uterine leiomyomas may present multiple challenges, affecting the quality of life.

Endometriosis and Uterine Fibroids (Leiomyomata): Comorbidity, Risks and Implications

Uterine Fibroids (leiomyomata) and endometriosis affect millions of women world-wide. Although aetiology and natural history of the conditions are markedly different, symptoms can overlap and make differential diagnoses necessary, often using invasive methods such as laparoscopy. Considerable comorbidity exists between the two conditions and needs to be taken into account when treating fibroids and/or endometriosis. The genetic foundations of both uterine fibroids and endometriosis remain to be fully understood but recent evidence suggest common underpinnings. Here, we discuss the comorbidity of uterine fibroids and endometriosis and the implications for diagnosis, treatment and risks.
