Diagnosis and Therapy of Endometriosis. Guideline of the DGGG, OEGGG and SGGG (S2k-Level, AWMF Registry No. 015/045, April 2025)

<b>Objective</b> The objective of this revised official guideline, published by the German Society for Gynecology and Obstetrics (DGGG) and coordinated in the joint guidelines program of the DGGG, the Austrian Society for Gynecology and Obstetrics (OEGGG), and the Swiss Society for Gynecology and Obstetrics (SGGG), is to provide evidence-based and consensus-based recommendations for the diagnosis, treatment, care, and support of girls and women with confirmed or suspected endometriosis. <b>Methods</b> This S2k guideline was developed through a structured consensus process involving representative members of various professions (37 professional associations, organizations, and self-help groups) and includes 25 statements and 73 recommendations which are based on a systematic literature review (2019 - 2023) and expert consensus. <b>Recommendations</b> For the first time, the revised guideline has placed a greater focus on individualized, symptom-oriented diagnosis and treatment that combines hormonal, surgical, and multimodal approaches. A significant innovation is the use of transvaginal ultrasound as the central diagnostic procedure for detecting endometriosis. Therapeutically, primary hormone treatment is now recommended as the first choice approach, with surgical interventions and multimodal approaches supplemented on an individual and symptom-oriented basis.
