Endometriosis Clinical Trial
Official title:
Maintenance Therapy of LNG-IUS in Conjunction With the GnRH Agonist to Prevent the Recurrence of Symptomatic Endometriosis After Conservative Surgery: A Prospective Randomized, Phase III Trial
The recurrence rates of endometriosis reported in women 5 years after therapy with
gonadotropin releasing hormone (GnRH) agonist were 74% for severe disease . No strategies to
prevent the recurrence of endometriosis have been uniformly successful. Local progesterone
treatment of endometriosis-associated dysmenorrhea with a levonorgestrel-releasing
intrauterine system (LNG-IUS) for 12 months has resulted in a significant reduction in
dysmenorrhea, pelvic pain and dyspareunia; a high degree of patient satisfaction; and a
significant reduction in the volume of rectovaginal endometriotic nodules. LNG-IUS may
become a more important option if a long-term medical suppression of endometriosis.
Based on literature review, I hypothesized that maintenance therapy of LNG-IUS in
conjunction with the GnRH agonist could lower the recurrence rates endometriosis after
conservative surgery. We try to answer the question whether maintenance therapy of LNG-IUS
in conjunction with the GnRH agonist could lower the recurrence rates and thus extend the
symptom-free interval (menorrhagia and dysmenorrhea) as compared to GnRH agonist alone after
conservative surgery in severe endometriosis cases.
