Formalin-fixed paraffin-embedded (FFPE) tissues represent an invaluable resource for both basic and clinical research due to their stable preservation of tissue architecture and molecular integrity. Multiplex immunofluorescence (mIF) using …

Background/Objectives: The scientific community is still divided between supporters of the implantation theory and researchers who advocate the theory of coelomic metaplasia/embryonic cell remnants to explain the initiation of endometriosis…

Background/Objectives: The assessment of endometriosis (EMS)-associated pain is important, but only very few studies address the potential use of questionnaires for non-invasive prediction of the disease. Methods: In a prospective observati…

Anogenital distance (AGD) is regarded as a potential biomarker for endometriosis, and a measurement on MRI images has been found to be promising. This study aimed to evaluate the measurement of AGD on MRI to predict the surgical diagnosis o…

OBJECTIVES: This study aimed to analyze the prevalence and clinical significance of incidental findings on MRI for endometriosis. Differences between patients with and without evidence of deep infiltrating endometriosis on MRI were to be ex…

Introduction After puberty, at least 10% of all women and girls suffer from endometriosis. Surgery is useful for both the diagnosis and therapy. To date, quality indicators for the surgical treatment of endometriosis are lacking. QS ENDO ai…

The changes in endometrial cells, both in the eutopic endometrium of patients with and without endometriosis and in lesions at ectopic sites, are frequently described and often compared to tumorigenesis. In tumorigenesis, the concept of "se…

Objectives The purpose of this investigation was to evaluate the inter- and intraobserver variability of the updated #Enzian classification of endometriosis on MRI and to evaluate the influence of reader experience on interobserver concorda…

Several current guidelines recommend imaging in the diagnostic work-up of deep infiltrating endometriosis (DIE). The purpose of this retrospective diagnostic test study was to evaluate the diagnostic accuracy of MRI compared to laparoscopy …

In the pathogenesis of endometriosis, the differences between the eutopic and ectopic endometrium as well as between the eutopic endometrium with and without endometriosis are repeatedly pointed out. Various mechanisms have been suggested t…

OBJECTIVES: Are other pain symptoms in addition to dysmenorrhea, dyspareunia, dyschezia, dysuria, and chronic pelvic pain correlated to endometriosis and suitable for a clinical prediction model? METHODS: We conducted a prospective study fr…

Abstract Introduction Endometriosis significantly reduces patientsʼ quality of life and is additionally a burden on healthcare and social security systems. There are currently no quality indicators for the treatment of endometriosis. The ca…

Claudins, as the major components of tight junctions, are crucial for epithelial cell-to-cell contacts. Recently, we showed that in endometriosis, the endometrial epithelial phenotype is highly conserved, with only minor alterations. For ex…

Abstract Background Postoperative pain remains a common problem in gynecologic laparoscopy, especially in head zone-related regions, triggered by intra-abdominal pressure during capnoperitoneum. Humidified and prewarmed insufflation gas may…

Hintergrund und Fragestellung: Endometriose ist eine der häufigsten Erkrankungen von Frauen in der reproduktiven Lebensphase mit den typischen Symptomen Dysmenorrhoe, Unterbauchschmerzen und Fertilitätsstörungen. Die Verzögerung der Diagnos…

Endometriosis affects a significant number of young premenopausal women. Quite apart from the medical challenges, endometriosis is a relevant burden for healthcare and social security systems. Standardized quality indicators for the treatme…

The implementation of a quality assurance program in endometriosis QS ENDO was initiated to evaluate the actual pattern of endometriosis care in German- speaking countries.br After the first phase (QS ENDO Real) which will yield an overview…
