Comparison of enhanced laparoscopic imaging techniques in endometriosis surgery: a diagnostic accuracy study.

Background: For surgical endometriosis, treatment key is to properly identify the peritoneal lesions. The aim of this clinical study was to investigate if advanced imaging improves the detection rate by comparing narrow-band imaging (NBI), near-infrared imaging with indocyanine green (NIR-ICG), or three-dimensional white-light imaging (3D), to conventional two-dimensional white-light imaging (2D) for the detection of peritoneal endometriotic lesions.

Methods: This study was a prospective, single-center, randomized within-subject, clinical trial.

Robotic single-site endometriosis resection using near-infrared fluorescence imaging with indocyanine green: a prospective case series and review of literature.

We present our preliminary experience comparing robotic near-infrared fluorescence (NIRF) imaging using indocyanine green (ICG) to 2D laparoscopic white light (WL) and 3D robotic WL illumination, in their ability to visually detect endometriosis lesions during a robotic endometriosis resection procedure in a single center. A total of twenty women were screened and seven of them with symptomatic endometriosis were included in this prospective case series. The mean patient age was 33 years with the mean body mass index being 28.

Iatrogenic endometriosis harbors somatic cancer-driver mutations.

Study Question: Does incisional endometriosis (IE) harbor somatic cancer-driver mutations?

Summary Answer: We found that approximately one-quarter of IE cases harbor somatic-cancer mutations, which commonly affect components of the MAPK/RAS or PI3K-Akt-mTor signaling pathways.

What Is Known Already: Despite the classification of endometriosis as a benign gynecological disease, it shares key features with cancers such as resistance to apoptosis and stimulation of angiogenesis and is well-established as the precursor of clear cell and endometrioid ovarian carcinomas. Our group has recently shown that deep infiltrating endometriosis (DE), a form of endometriosis that rarely undergoes malignant transformation, harbors recurrent somatic mutations.

Analysis of menstrual effluent: diagnostic potential for endometriosis.

Background: Endometriosis is a chronic and underdiagnosed disease which affects 5-10% of women of childbearing age and is characterized by growth of endometrial tissue outside of the uterus, most often in the peritoneal cavity. Delay in diagnosis is a major problem for management of this disorder, and treatment is often not initiated until the disease has progressed for many years. Although the exact etiology of endometriosis remains unknown, retrograde menstruation is recognized as a common underlying factor leading to the deposit of menstrual effluent (ME) into the peritoneal cavity.

Recommendations for the surgical treatment of endometriosis-part 1: ovarian endometrioma.

Study Question: What does this document on the surgical treatment of endometriosis jointly prepared by the European Society for Gynaecological Endoscopy (ESGE), ESHRE, and the World Endometriosis Society (WES) provide?

Summary Answer: This document provides recommendations covering technical aspects of different methods of surgery for endometriomas in women of reproductive age.

What Is Already Known: Endometriomas (ovarian endometriotic cysts) are a commonly diagnosed form of endometriosis, owing to the relative ease and accuracy of ultrasound diagnosis. They frequently present a clinical dilemma as to whether and how to treat them when found during imaging or incidentally during surgery.

Spontaneous hemoperitoneum in pregnancy (SHiP) and endometriosis - A systematic review of the recent literature.

Spontaneous Hemoperitoneum in Pregnancy (SHiP), an unprovoked (nontraumatic) intraperitoneal bleeding in pregnancy (up to 42days postpartum), is associated with serious adverse pregnancy outcomes. To evaluate the clinical consequences of SHiP and its association with endometriosis, a systematic review was conducted according to the PRISMA guidelines. PubMed, Embase.

Genetic risk factors for ovarian cancer and their role for endometriosis risk.

Objective: Several genetic variants have been validated as risk factors for ovarian cancer. Endometriosis has also been described as a risk factor for ovarian cancer. Identifying genetic risk factors that are common to the two diseases might help improve our understanding of the molecular pathogenesis potentially linking the two conditions.

Laparoscopic Imaging Techniques in Endometriosis Therapy: A Systematic Review.

Endometriosis is a common disease associated with pelvic pain and subfertility. Laparoscopic surgical treatment has proven effective in endometriosis, but is hampered by a high rate of recurrence. The aim of this systematic review was to evaluate the intraoperative identification of endometriosis by enhanced laparoscopic imaging techniques, focusing on sensitivity and specificity.

Fertility outcome of laparoscopic treatment in patients with severe endometriosis and repeated in vitro fertilization failures.

Objective: To evaluate fertility outcomes in infertile women with severe endometriosis (The revised American Fertility Society classification [AFS] 3-4) and repeated IVF failures, who underwent surgery due to exacerbation of endometriosis-related symptoms.

Design: Retrospective cohort study.

Setting: University hospital.

Severe spontaneous hemoperitoneum in pregnancy may be linked to in vitro fertilization in patients with endometriosis: a systematic review.

Objective: To evaluate existing evidence of a possible association in women with endometriosis between controlled ovarian hyperstimulation plus embryo transfer (COH-ET) and the occurrence of spontaneous hemoperitoneum in pregnancy (SHiP).

Design: Comprehensive review.

Setting: Not applicable.

Challenges in the development of novel therapeutic strategies for treatment of endometriosis.

Introduction: Endometriosis is an estrogen-dependent disease that results in pelvic pain and infertility. Its treatment is often frustrating due to limited medical treatment options, complex surgical treatment and high recurrence rates. Despite the advances in our understanding of the pathogenesis over the last decades and the consequent novel therapeutic strategies, no new drugs have been introduced in daily clinical practice.

How to Develop an Electronic Clinical Endometriosis Research File Integrated in Clinical Practice.

Endometriosis is associated with a range of pelvic-abdominal pain symptoms and infertility. It is a chronic disease that can have a significant impact on various aspects of women's lives, including their social and sexual relationships, work, and study. Despite several international guidelines on the management of endometriosis, there is a wide variety of clinical practice in the management of endometriosis, resulting in many women receiving delayed or suboptimal care.

National German Guideline (S2k): Guideline for the Diagnosis and Treatment of Endometriosis: Long Version - AWMF Registry No. 015-045.

In this guideline, recommendations and standards for optimum diagnosis and treatment of endometriosis are presented. They are based on the analysis of the available scientific evidence as published in prospective randomized and retrospective studies as well as in systematic reviews. The guideline working group consisted of experts from Austria, Germany, Switzerland, and the Czech Republic.

The relationship among HOXA10, estrogen receptor α, progesterone receptor, and progesterone receptor B proteins in rectosigmoid endometriosis: a tissue microarray study.

Background: Very few studies have evaluated the expression of homeobox A10 (HOXA10) and steroid (estrogen and progesterone) receptors exclusively in deep endometriosis. Conclusions drawn from studies evaluating peritoneal and ovarian endometriosis are usually generalized to explain the pathogenesis of the disease as a whole. We aimed to evaluate the expression of HOXA10, estrogen receptor α (ER-α), progesterone receptor (PR), and PR-B in rectosigmoid endometriosis (RE), a typical model of deep disease.

Patient satisfaction concerning assisted reproductive technology treatments in moderate to severe endometriosis.

A prospective observational cohort study was performed to examine patient satisfaction after one Assisted Reproductive Technology (ART) treatment cycle in moderate to severe endometriosis patients. From May 2012 till September 2013, 25 patients with surgically proven endometriosis stage III-IV were included per group and received intrauterine insemination (IUI), in vitro fertilization (IVF) or IVF preceded by long-term pituitary down-regulation (IVF-ultralong). The median patient satisfaction scores were 8.

The peritoneum--an important factor for pathogenesis and pain generation in endometriosis.

Endometriosis (EM) is an oestrogen-dependent disease affecting 10-15 % of women during reproductive age. It is characterised by the presence of endometrial glands, stromal- and smooth muscle-like cells outside of the uterine cavity. Fifty to sixty per cent of women and teenage girls with pelvic pain suffer from EM.

Implementation of certified endometriosis centers: 5-year experience in German-speaking Europe.

The idea of quality improvement in the management of endometriosis has been brought to attention throughout Europe. This - first and foremost - includes the implementation of centers specialized in treating endometriosis. This leads to qualification of both physicians and other medical staff, enforcement of research efforts, and informing the patients, the public, politicians, healthcare providers, and industry.

Deep infiltrating endometriosis of the bowel: MR imaging as a method to predict muscular invasion.

Purpose: To evaluate magnetic resonance (MR) imaging morphologic- and signal intensity abnormalities of deep infiltrating endometriosis (DIE) of the bowel wall and to assess its value in predicting depth and extent of bowel wall infiltration.

Materials And Methods: This single-center study was performed in a tertiary referral center for endometriosis. All patients (n = 28) who underwent segmental bowel resection (2004-2010) were retrospectively studied.

Anaphylactic reaction to different gonadotropin-releasing hormone agonists for the treatment of endometriosis.

Anaphylactic reactions to gonadotropin-releasing hormone (GnRH) agonists are exceedingly rare, but if they occur, they can be life threatening. This case describes a 33-year-old patient with endometriosis who developed an acute allergic reaction on leuprolide (Lucrin) administration. Although skin tests with the replacement goserelin (Zoladex) were negative, usage of this medication resulted in a similar allergic reaction.

Dietary therapy: a new strategy for management of chronic pelvic pain.

Chronic pelvic pain (CPP) can be identified as a chronic nociceptive, inflammatory and neuropathic pain characterised by spontaneous pain and an exaggerated response to painful and/or innocuous stimuli. This pain condition is extremely debilitating and usually difficult to treat. Currently, the main approaches to treatment include counselling supported by reassuring ultrasound scanning or psychotherapy, attempting to provide reassurance using laparoscopy to exclude serious pelvic pathology, hormonal therapy and neuroablative treatment to interrupt nerve pathways.

Magnetic resonance imaging in the evaluation of (deep infiltrating) endometriosis: the value of diffusion-weighted imaging.

Purpose: To assess the value of magnetic resonance (MR)diffusion-weighted imaging (DWI) in the evaluation of deep infiltrating endometriosis (DIE).

Materials And Methods: In a prospective single-center study, DWI was added to the standard MRI protocol in 56 consecutive patients with known or suspected endometriosis. Endometriotic lesions as well as (functional) ovarian cysts were analyzed for location, size, and signal intensity on T1, T2, and DWI.
