title: Comparison of a levonorgestrel-releasing intrauterine device versus expectant management after conservative surgery for symptomatic endometriosis: a pilot study.
abstract: OBJECTIVE
  To determine whether the frequency and severity of dysmenorrhea are reduced in women with symptomatic endometriosis in whom a levonorgestrel-releasing intrauterine device (Lng-IUD) is inserted after operative laparoscopy compared with those treated with surgery only.
  
  
  METHODS
  Open-label, parallel-group, randomized, controlled trial.
  
  
  METHODS
  A tertiary care and referral center for patients with endometriosis.
  
  
  METHODS
  Parous women with moderate or severe dysmenorrhea undergoing first-line operative laparoscopy for symptomatic endometriosis.
  
  
  METHODS
  Randomization to immediate Lng-IUD insertion or expectant management after laparoscopic treatment of endometriotic lesions. Proportions of women with recurrence of moderate or severe dysmenorrhea in the two study groups 1 year after surgery and overall degree of satisfaction with treatment. Moderate or severe dysmenorrhea recurred in 2 of 20 (10%) subjects in the postoperative Lng-IUD group and 9/20 (45%) in the surgery-only group. Thus, a medicated device inserted postoperatively will prevent the recurrence of moderate or severe dysmenorrhea in one out of three patients 1 year after surgery. A total of 15/20 (75%) women in the Lng-IUD group and 10/20 (50%) in the expectant management group were satisfied or very satisfied with the treatment received.
  
  
  CONCLUSIONS
  Insertion of an Lng-IUD after laparoscopic surgery for symptomatic endometriosis significantly reduced the medium-term risk of recurrence of moderate or severe dysmenorrhea.
