Background: Extrauterine pregnancy is a complication of the first trimester of pregnancy that arises in 1.3-2.4% of all pregnancies.
Methods: This review is based on articles and guidelines retrieved by a selective PubMed search.
Results: The presentation of extrauterine pregnancy is highly variable, ranging from an asymptomatic state, to pelvic pain that is worse on one side, to tubal rupture with hemorrhagic shock. 75% of tubal pre gnancies can be detected by transvaginal ultrasonography. In patients with a vital extrauterine pregnancy, the human chorionic gonadotropin concentration generally doubles within 48 hours. Laparoscopy is the gold standard of treatment. Two randomized, controlled trials comparing organ-preserving treatment with ablative surgery revealed no significant difference in pregnancy rates after the intervention, but precise details of the surgical procedures were not provided, and long-term fertility data are lacking. Metho - trexate therapy should be used only for strict indications.
Conclusion: Further randomized, controlled trials with longer follow-up will be needed to answer currently open questions about the potential for individualized surgical treatment and the proper role of pharmacotherapy.
