Importance: Endometriosis is an inflammatory disease, with different forms of expression and a variety of complaints. An endometrioma, an ovarian cyst with endometrium-like lining, is one of the most common expressions of abdominal endometriosis. These endometriomas can, in addition to medical treatment, be treated surgically.

Endometriosis is an estrogen-dependent chronic disease characterized by the presence of endometriumlike tissue outside the uterus and is often associated with symptoms, such as dysmenorrhea, dysuria, dyschezia, chronic pelvic pain, and infertility. Moreover, women diagnosed with endometriosis can report gastrointestinal symptoms, including bloating, constipation or diarrhea, and abdominal cramping, which can be associated with irritable bowel syndrome and can result in the misdiagnosis of endometriosis as irritable bowel syndrome at first. Treatment usually involves hormonal therapy, pain management, surgery, and/or assisted reproductive techniques in case of infertility.

Currently, the optimal treatment to increase the chance of pregnancy and live birth in patients with colorectal endometriosis and subfertility is unknown. Evidence suggests that that both surgery and in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) are effective in improving live birth rate (LBR) among these women. However, the available evidence is of low quality, reports highly heterogeneous results, lacks direct comparison between both treatment options and does not assess whether a combination strategy results in a higher LBR compared to IVF/ICSI-only treatment.

Article Synopsis
  • Endometriosis is when tissue similar to the lining of the uterus grows outside of it, causing pain and other symptoms, but it's not clear why this happens.
  • Some people think that eating a gluten-free diet might help reduce pain from endometriosis, but research on this is mixed and not very strong.
  • Studies suggest that certain diets, like avoiding red meat and eating more fruits and vegetables, might improve symptoms, but many of these studies had issues that make the results less reliable.

Background: Endometriosis is a common gynaecological condition affecting 6 to 11% of reproductive-age women and may cause dyspareunia, dysmenorrhoea, and infertility. One treatment strategy is medical therapy with gonadotrophin-releasing hormone analogues (GnRHas) to reduce pain due to endometriosis. One of the adverse effects of GnRHas is a decreased bone mineral density.

Objective: The objective of this study was to examine the hypothesis that experiences with patient-centered endometriosis care are related to the endometriosis-specific quality of life dimensions "emotional well-being" and "social support."

Design: A secondary regression analysis of two cross-sectional studies was conducted. Participants/Materials: In total, data from 300 women were eligible for analysis.

Background: Sexual function after hysterectomy can be a concern for patients, and research remains inconclusive about changes in sexual function associated with hysterectomy.

Aim: We meta-analyzed studies on change in sexual function from pre- to posthysterectomy and the role of total vs subtotal hysterectomy and concomitant bilateral salpingo-oophorectomy (BSO) in differences in such change.

Methods: We searched PubMed, Embase, and Cochrane databases from inception to January 2022.

Objective: To evaluate the effect of an informative 360-degree virtual reality (VR) video on preoperative anxiety before visiting a one-stop clinic for abnormal uterine bleeding.

Study Design: A randomized controlled trial was performed in a teaching hospital in the Netherlands. A total of 83 women scheduled for a first consultation at the one-stop clinic between April 2017 and September 2017 were included in the analysis.

Objective: Endometriosis is a chronic gynaecologic disease, causing pain and infertility. As there is no definitive cure, patients are subjected to long-term care. This study aimed to improve patient-centred endometriosis care.

Research Question: How do infertility patients, endometriosis patients and health-care providers rate virtual care as an alternative to physical consultations during the first lockdown of the coronavirus disease 2019 (COVID-19) pandemic in the Netherlands, and how does this influence quality of life and quality of care?

Design: Infertility patients and endometriosis patients from a university hospital and members of national patient organizations, as well as healthcare providers in infertility and endometriosis care, were asked to participate between May and October 2020. The distributed online questionnaires consisted of an appraisal of virtual care and an assessment of fertility-related quality of life (FertiQol) and patient-centredness of endometriosis care (ENDOCARE).

Results: Questionnaires were returned by 330 infertility patients, 181 endometriosis patients and 101 healthcare providers.

Objective: To assess the influence of surgical approach, complications and patient characteristics and their postoperative functional outcomes on (sexual) quality of life (QoL) in patients with deep endometriosis (DE) with bowel involvement.

Methods: Retrospective cohort study on patients surgically treated for DE in a Dutch tertiary referral hospital. Data are based on surgical records and questionnaires covering current postoperative bowel function and (sexual) QoL.

Introduction: In vitro fertilisation (IVF) has evolved as an intervention of choice to help couples with infertility to conceive. In the last decade, a strategy change in the day of embryo transfer has been developed. Many IVF centres choose nowadays to transfer at later stages of embryo development, for example, transferring embryos at blastocyst stage instead of cleavage stage.

Article Synopsis
  • Endometriosis affects 10%-15% of women of reproductive age, causing pain and infertility, and one treatment approach is the combination of surgery and medical therapy to prevent its recurrence.
  • The study aims to evaluate the effectiveness of hormonal medical therapies in relation to the timing of surgery—whether administered before, after, or both—to alleviate pain, reduce recurrence, and improve pregnancy rates.
  • Researchers conducted a systematic review of randomized controlled trials, analyzing pain levels and disease recurrence through various measurement scales and risk ratios to determine the best treatment timing.*

Introduction: Endometriosis is a benign gynecological disease with a high disease burden and significant, multifaceted impact on health-related quality of life (HRQoL) and sexual quality of life (SQoL).

Aim: To explore which patient- and disease-specific characteristics were independently associated with SQoL.

Methods: A literature search was carried out to identify characteristics with an evidence-based or hypothesized effect on SQoL.

Objectives: All patients undergoing a laparoscopic hysterectomy receive an indwelling catheter during surgery. The optimum timing of removal of the catheter is uncertain. A possible advantage of leaving the catheter in up to 12 h after surgery is to reduce the risk of urinary retention.

Objectives: Research about sexual function after hysterectomy is inconclusive. Possible predictive factors for sexual (dys)function are yet to be identified. The aim of this study is to assess the effect of hysterectomy on sexual function in women 3 and 12 months after hysterectomy for benign indications.

Chronic postsurgical pain (CPSP) is 1 important aspect of surgical recovery. To improve perioperative care and postoperative recovery knowledge on predictors of impaired recovery is essential. The aim of this study is to assess predictors and epidemiological data of CPSP, physical functioning (SF-36PF, 0-100), and global surgical recovery (global surgical recovery index, 0-100%) 3 and 12 months after hysterectomy for benign indication.
