Ovarian Endometrioma: What the Patient Needs

Impact of endometriosis on obstetric outcome after natural conception: a multicenter Italian study

Purpose

To evaluate obstetric outcome in women with endometriosis who conceive naturally and receive standard obstetric care in Italy.

Methods

Cases were consecutive women with endometriosis managed in eleven Italian referral centers. Controls were women in whom endometriosis was excluded. All women filled in a questionnaire addressing previous natural pregnancies. Marginal logistic regression models were fitted to evaluate the impact of endometriosis on obstetric outcome. A post hoc analysis was performed within the endometriosis group comparing women with severe adenomyosis versus women with absent or mild adenomyosis.

Results

Three hundred and fifty-five pregnancies in endometriosis group and 741 pregnancies in control group were included. Women with endometriosis had a higher risk of preterm delivery < 34 weeks (6.4% vs 2.8%, OR 2.42, 95% CI 1.22–4.82), preterm delivery < 37 weeks (17.8% vs 9.7%, OR 1.98, 95% CI 1.23–3.19), and neonatal admission to Intensive Care Unit (14.1% vs 7.0%, OR 2.04, 95% CI 1.23–3.36). At post hoc analysis, women with endometriosis and severe adenomyosis had an increased risk of placenta previa (23.1% vs 1.8%, OR 16.68, 95% CI 3.49–79.71), cesarean delivery (84.6% vs 38.9%, OR 8.03, 95% CI 1.69–38.25) and preterm delivery < 34 weeks (23.1% vs 5.7%, OR 5.52, 95% CI 1.38–22.09).

Conclusion

Women with endometriosis who conceive naturally have increased risk of preterm delivery and neonatal admission to intensive care unit. When severe adenomyosis is coexistent with endometriosis, women may be at increased risk of placenta previa and cesarean delivery.

Coexistence of endometriomas with extraovarian endometriosis and adhesions

OBJECTIVE

The aim of the study is to show the coexistence of the endometriomas with peritoneal and deep infiltrating endometriosis, as well as with the adhesions. Study design It's a randomized retrospective study. Patients treated for endometrioma at Academic Hospital Cologne Weyertal from January 2014 to October 2019 were included. In total there were 1054 patients. 310 medical records were chosen at random without a special selection and the data were analysed.

RESULTS

In our study, endometriomas were alone, which means without extraovarian endometriosis and/or adhesions, in only 2.3% of the cases. In the total population, 80.6% (250) of the patients had peritoneal endometriosis, 43.2% (134) of the patients had deep infiltrating endometriosis and 38% (118) of the patients had peritoneal and deep infiltrating endometriosis. In our analysis we found that in unilateral endometriomas there is no relationship between endometrioma size and adnexal adhesions. The risk of Douglas obliteration increases with the size of the endometriomas in unilateral endometriomas. In bilateral endometriomas, the risk of a complex adhesions is independent of the size of the endometriomas and relevantly higher than in unilateral endometriomas (Douglas obliteration 31.5% vs 16%, bilateral adnexal adhesions 45.2% vs 21.1%). Unilateral adnexal adhesions occurred in bilateral endometriomas only in 13.7%.

CONCLUSION

Endometriomas are the relevant problem in gynaecological practice. It must be taken into account here that endometriomas usually occur with peritoneal endometriosis and that surgical therapy may be useful. However, adhesions and DIE are to be expected with surgical treatment, which could make the operation more difficult. Especially in large and bilateral endometriomas, a high coexistence with extraovarian endometriomas and adhesions is observed. Therefore, surgery should be performed by an experienced surgeon.

Long-Term Medical Therapy after Laparoscopic Excision of Ovarian Endometriomas: Can We Reduce and Predict the Risk of Recurrence?

OBJECTIVES

Up to 32% of women experience anatomic recurrence after conservative surgery for endometriomas, while pain recurs in 10-40% of cases. Long-term postoperative hormonal therapy is recommended to prevent disease recurrence. We evaluated the efficacy of long-term therapy with estroprogestins (EPs) or progestins (Ps) in preventing endometrioma recurrence, as identifiable cysts and subjective symptoms, after laparoscopic excision.

DESIGN

This retrospective cohort study included 375 women submitted to laparoscopic endometrioma excision. Women were followed up at 6 and 12 months and then yearly after surgery. Based on postoperative medical therapy, women were divided into 4 groups: nonusers, cyclic EP users, continuous EP users, and progestogen users. Materials, Setting, Methods: Anamnestic and anthropometric characteristics were collected as well as clinical and surgical data. Gynecological examination, and transvaginal and transabdominal ultrasound scans were performed. Pain (numerical rating score >5) and endometrioma recurrence at ultrasound (ovarian cyst with typical sonographic features ≥10 mm in mean diameter) were recorded at each examination. The reoperation rate in women with recurrence was investigated.

RESULTS

The median follow-up was 3.7 years with a maximum of 16.7 years. Most patients used EPs (119 cyclic and 61 continuous users), 95 used P, and 100 were nonusers. In 135 women (36%), endometriotic cyst recurrence was diagnosed, with a mean diameter of 18.7 ± 10.8 mm (range 10-55 mm). The median recurrent cyst-free time was 7.9 years (95% CI 5.8-10.8). Dysmenorrhea was the first symptom to reappear, affecting 162 patients (43.2%). Upon multivariable regression analysis, continuous users had a lower risk of relapse (OR 0.56, 95% CI 0.32-0.99), in terms of both cysts and symptom recurrence, than patients who received no medications. The reoperation rate was 16.2%.

LIMITATIONS

The main limitation of this study is its retrospective design. Also, women switching therapies throughout the follow-up period were sorted into one of the study groups based on the longest treatment taken, without considering the discontinuation rates.

CONCLUSIONS

Long-term EPs, administered in a continuous regimen and starting immediately after conservative surgery for endometriomas, seem to reduce the disease recurrence risk.

The Endometrioma Treatment Paradigm when Fertility Is Desired: A Systematic Review

OBJECTIVE

To establish an endometrioma treatment paradigm (decision tree) in the treatment of an ovarian endometrioma through the review of current literature.

DATA SOURCES

A thorough literature search, including PubMed, Google Scholar, and the Cochrane Library, was performed from April 2020 to July 2020. The review was completed by using the following keywords: METHODS OF STUDY SELECTION: Articles published in English that addressed the endometrioma in regard to the following were included: (1) diagnosis, (2) treatment of pain on the basis of size and/or surgical intervention, (3) treatment of fertility on the basis of size and/or surgical intervention, (4) surgical technique, (5) in vitro fertilization success on the basis of size and/or surgical intervention, (6) risk of rupture at the time of egg retrieval, (7) impact on the antimüllerian hormone and antral follicle count postsurgery, and (8) impact on implantation.

TABULATION, INTEGRATION, AND RESULTS

Fifty-six articles were included in this systematic review. While conducting this literature review, several themes were noted. In general, the literature on the ovarian endometrioma seems to be homogeneous in regard to imaging the endometrioma, excision rather than desiccation for an endometrioma ≥3-cm causing pain and/or infertility, minimal use of bipolar energy at the time of ovarian surgery, and risk of severe infection secondary to inadvertent rupture of cysts during egg retrieval. Conversely, studies on the ovarian endometrioma are much more heterogeneous in terms of surgery and assisted reproductive technology, that is, whether surgery should be performed. Certainly, an endometrioma ≥5-cm should be excised before assisted reproductive technology. Moreover, it seems that the antral follicle count and implantation may be enhanced with surgery.

CONCLUSION

By completing an extensive literature review, an easy-to-use algorithm for the diagnosis, evaluation, and treatment of endometriomas was developed to help clinicians in their treatment of patients with endometriosis in the short and long terms.

State of the art and emerging drug therapies for female infertility

At present, infertility is a key-issue. When applicable, in vitro fertilization (IVF) has become the standard approach to treat this condition but a thorough investigation and, whenever possible, the individual diagnosis of the underlying causes of infertility are required. For many female causes, indeed, efficient medical therapies are available to achieve a fast solution of the problem. This review is based on the relevant literature indexed in PubMed and SCOPUS and is focused on the most recent clinical literature on the treatment of women (and couples) affected from infertility. The reduction in IVF treatment burden and risks are now considered pivotal to set 'patient-friendly' therapies and represent crucial issues for both patients and physicians. To this end, the researchers are now focusing their attention on old drugs with new indications and new compounds with more appropriate functions, to improve the compliance of the women and reduce the burden of infertility, a condition that is becoming an important issue in the modern world, also for the Public Health System.

Management of Endometriomas Prior to IVF

Endometriosis causes a decrease in fertility in affected patients. The different forms of the disease, peritoneal, ovarian, deep infiltrating and adenomyosis, are often present in varying degrees in the same patient, either together or individually, and cause infertility through a pathogenesis that is not yet clear. A significant number of women with endometriosis and endometriomas will eventually seek assisted reproductive technology (ART) for conception. The specific impact of endometriomas alone and the impact of surgical intervention for endometriomas on the reproductive outcome of women undergoing in vitro fertilization/intra-cytoplasmic sperm injection (IVF/ICSI) are areas that need further clarification and, for this reason, the management of endometriomas before clinical IVF is a very complex topic.

In order to provide useful information for the clinical management of patients with endometriomas having IVF, in this review we investigated: the impact of the presence of endometriomas, both individually and associated with other types of the disease, on IVF techniques; the possible role of surgery and its possible negative effects; the risks and difficulties related to conservative management during IVF procedures.

Endometriosis and perceived stress: impact of surgical and medical treatment

BACKGROUND

The aim of the study was to investigate the levels of perceived stress in a group of women with a long-term history of endometriosis in conjunction with surgical and/or medical treatments.

METHODS

A clinical trial was conducted at the Department of Molecular and Developmental Medicine, University of Siena, in collaboration with a non-profit association of women with endometriosis, A.P.E. Onlus. Patients (n = 204) with a previous diagnosis of endometriosis (for at least 3 years) were included in this study. Each patient completed a semi-structured questionnaire and a validated scale to assess perceived stress, the Perceived Stress Scale (PSS) by e-mail.

RESULTS

The study showed that in women with a long-term history of endometriosis, the level of perceived stress was increased by repeated surgical treatments and reduced by some medical treatments. The median PSS value was 23 (range 9-36) and 30.6% of the study population were included in the highest stress category (>26). The highest levels were found in patients who had undergone the most surgery. The use of progestins was associated with a lower perceived stress (p = 0.004) than in the patients treated with gonadotropin-releasing hormones.

CONCLUSIONS

Long-term endometriosis has a relevant impact on perceived stress, in particular in those undergoing repeated surgery.
