title: A randomized study comparing triptorelin or expectant management following conservative laparoscopic surgery for symptomatic stage III-IV endometriosis.
abstract: OBJECTIVE
  To investigate the role of adjuvant treatment with gonadotropin-releasing-hormone agonist (GnRHa) following conservative surgical treatment of endometriosis.
  
  
  METHODS
  Sixty patients in the reproductive age (mean age 28.6 years), with symptomatic stages III and IV endometriosis following laparoscopic surgery and without previous hormonal treatment were enrolled in a prospective, randomized, controlled trial to compare the effects of 3-month treatment with triptorelin depot-3.75 i.m. (30 patients) versus expectant management using placebo injection (30 patients).
  
  
  RESULTS
  Six patients (one in triptorelin group and five in placebo group) were lost at follow-up, the remaining 54 were suitable for analysis. Pelvic pain persistence or recurrence, endometrioma relapses and pregnancy rate were evaluated during a 5-year follow-up. The results of 29 cases treated with triptorelin and 25 that received placebo did not show significant differences in pain recurrence (P=1, RR=0.94, 95% CI=0.57-1.55), endometrioma relapse (P=0.67, RR=1.29, 95% CI=0.66-2.50), and pregnancy rate in infertile women (P=0.80, RR=0.81, 95% CI=0.37-1.80). Curves of time of pain recurrence and pregnancy during 5-year follow-up did not show significant differences between the two groups (P=0.79 and P=0.51, respectively, using Mantel-Haenzsel logrank test).
  
  
  CONCLUSIONS
  Triptorelin treatment after operative laparoscopy for stage III/IV endometriosis does not appear to be superior to expectant management in terms of prevention of symptoms recurrence and endometrioma relapse, and has no influence on pregnancy rate in endometriosis-associated infertility.
