Lay summary: Adenomyosis and endometriosis are two sister diseases that cause menstrual pain and other symptoms. We have previously reported that patients with these conditions have a less active "calm-and-rest" system and a more active "st…

Objectives: The peritoneal cavity is a cavity outside the bloodstream, with a specific hormonal, immunological and microbiological micro-environment distinct from plasma. The mesothelial cells lining the peritoneal cavity react within secon…

• The limitations of EBM and guidelines to take dichotomous decisions, based on multiple variables, are discussed for endometriosis management. • It is suggested to document for clinical decisions on diagnosis, treatment and surgery the col…

Objectives: Retrograde menstruation occurs in most women and could cause some peri-toneal irritation. The peritoneal cavity is a cavity outside the bloodstream, with a specific hormonal, immunological and microbiological micro-environment d…

Background/Objectives: The diagnosis and treatment of endometriosis should be based on the best available evidence. Emphasising the risk of bias, the pyramid of evidence has the double-blind, randomised controlled trial and its meta-analyse…

Objectives: The aim of this study was to review the importance of peritoneal fluid steroid hormone concentrations to understand the mechanism of hormonal medical treatment of endometriosis-associated pain. Design: The study included a PubMe…

Peritoneal fluid is an ovarian exudate from the growing follicle or corpus luteum. Therefore, the free concentrations of estrogens and progesterone are always much higher than in plasma, especially after ovulation. The peritoneum is not vas…

Background: Management of endometriosis should be based on the best available evidence. The pyramid of evidence reflects unbiased observations analysed with traditional statistics. Evidence-based medicine (EBM) is the clinical interpretatio…

Consequences of the shift from the use of non-invasive testing for diagnosis to screening purposes • As the high-throughput screening and sequencing become increasingly faster and affordable, that there will be a swell of commercial non-inv…

Adenomyosis is a disease defined by histopathology, mostly of hysterectomy specimens, and classification is challenged by the disagreement of the histologic definition. With the introduction of Magnetic Resonance Imaging (MRI) and two- and …

Segmental rectum resections for indications other than endometriosis were reported to result in up to 40% sexual dysfunctions. We, therefore, evaluated sexual function after low bowel resection (n = 33) for deep endometriosis in comparison …

Evidence-based data for endometriosis management are limited. Experiments are excluded without adequate animal models. Data are limited to symptomatic women and occasional observations. Hormonal medical therapy cannot be blinded if recognis…

Without an animal model and a non-invasive diagnosis, the pathophysiology of endometriosis is unclear and information is limited to symptomatic women. Lesions are biochemically variable. Medical therapy cannot be blinded and extensive surge…

Your article 'Endometrial preservation during resection of type II and type III submucosal fibroids' (Vorona and Saridogan, 2022) and the discussion on the healing of the endometrium, was read with interest.However, hysteroscopic resection …

For 100 years, pelvic endometriosis has been considered to originate from the implantation of endometrial cells following retrograde menstruation or metaplasia. Since some observations, such as the clonal aspect, the biochemical variability…

Background: Without an adequate animal model permitting experiments the pathophysiology of endometriosis remains unclear and without a non-invasive diagnosis, information is limited to symptomatic women. Lesions are macroscopically and bioc…
