title: Postoperative medical treatment of chronic pelvic pain related to severe endometriosis: levonorgestrel-releasing intrauterine system versus gonadotropin-releasing hormone analogue.
abstract: OBJECTIVE
  To compare efficacy of the levonorgestrel-releasing intrauterine system (LNG-IUS; Mirena) with depot GnRH analogue (GnRH-a; gosareline acetate; Zoladex) on endometriosis-related chronic pelvic pain (CPP) in patients with severe endometriosis during 12 months.
  
  
  METHODS
  Prospective, randomized, controlled study.
  
  
  METHODS
  The reproductive endocrinology unit of a tertiary, research and education hospital.
  
  
  METHODS
  Forty women with severe endometriosis (revised The American Fertility Society [AFS] classification >40) and endometriosis-related CPP and control groups were enrolled in the study.
  
  
  METHODS
  The patients were treated with either LNG-IUS (n = 20) or GnRH-a (n = 20). The GnRH-a dose was repeated every 4 weeks for 24 weeks.
  
  
  METHODS
  Scores of CPP were evaluated using a visual analogue scale (VAS) and total endometriosis severity profile (TESP).
  
  
  RESULTS
  The TESP score decreased in the LNG-IUS group at first, third, and sixth month follow-up visits, whereas at the 12th month follow-up visit, the TESP scores were increased to values similar to pretreatment values. Although the VAS score had no significant alteration during the follow-up period in the LNG-IUS group, the GnRH-a group showed a significant decrease in the VAS score and TESP score at the end of 1 year. The LNG-IUS treatment showed a lower patient satisfaction.
  
  
  CONCLUSIONS
  Both treatment modalities showed comparable effectiveness in the treatment of CPP-related endometriosis.
