Detailed Summary

This retrospective cohort study evaluates the association between postoperative hormonal treatment and recurrence of ovarian endometriosis in women undergoing surgery for ovarian endometrioma. The study includes patients treated at a single center who initiated one postoperative hormonal regimen after surgery. The main objective is to compare the risk of recurrence among women receiving combined oral contraceptives, gonadotropin-releasing hormone agonists, dienogest, or dydrogesterone. Recurrence is assessed during follow-up based on postoperative clinical and ultrasound findings. The results may help clarify the comparative effectiveness of commonly used postoperative hormonal strategies for reducing recurrence after surgery for ovarian endometrioma.
