Early Pregnancy Loss in the 1st Trimester: Guideline of the DGGG, OEGGG and SGGG (S2k-Level, AWMF Registry No. 015/076; August 2024).

This guideline aims to improve and standardize the diagnostic and therapeutic approaches for different types of miscarriages, pregnancies of unclear localization, and ectopic pregnancies in the 1st trimester. In accordance with the requirements for an S2k-guideline, this guideline was compiled following a search of the literature, and the various recommendations and statements were formally agreed upon by an interdisciplinary group of representative experts from Germany (DGGG, etc.), Austria (OEGGG) and Switzerland (SGGG) who met up several times under the aegis of the German Society for Gynecology and Obstetrics ( , DGGG). The guideline provides 129 recommendations on clinical, laboratory-based, ultrasonographical, pathomorphological and genetic diagnostics and describes and assesses different therapeutic options in terms of their success and complication rates and the continued fertility of the patient as well as aspects of the grieving process and coming to terms with the loss after an early loss of pregnancy.
