title: [Clinical study on the effectiveness and safety of combined laparoscopy and gonadotropin-releasing hormone agonist in the treatment of endometriosis].
abstract: OBJECTIVE
  To study the effectiveness and safety of combined laparoscopy and gonadotropin-releasing hormone agonist (GnRH-a) in the treatment of endometriosis (EM).
  
  
  METHODS
  From January to December 2010, 198 patients with EM undergoing treatment in Department of Obstetrics and Gynecology, Beijing Anzhen Hospital were randomly divided into three groups, which include 52 cases treated by only laparoscopy in laparoscopy group; 76 cases treated by laparoscopy combined with domestic Leuprolide acetate with dose of 3.75 mg every 28 days in Leuprolide acetate group; 70 cases treated by laparoscopy combined with imported Goserelin acetate with dose of 3.6 mg every 28 days in Goserelin acetate group. The efficacy, pregnancy rate and adverse reactions were compared among the three groups.
  
  
  RESULTS
  Thirteen cases lost following up, including 3 cases in laparoscopy group, 6 cases in Leuprolide acetate group and 4 cases in Goserelin acetate group. (1) Effective rates: effective rates were 47% (23/49) in laparoscopy group, 77% (54/70) in Leuprolide acetate group and 74% (49/66) in Goserelin acetate group. Compared with laparoscopy group, the effective rate of Leuprolide acetate group and Goserelin acetate group was significantly elevated (P < 0.05). There was no statistically significant difference between Leuprolide acetate group and Goserelin acetate group (P > 0.05).(2) Recurrence rate: recurrence rate were 33% (16/49) in laparoscopy group, 13% (9/70) in Leuprolide acetate group and 12% (8/66) in Goserelin acetate group. Compared with laparoscopy group, the recurrence rate of Leuprolide acetate group and Goserelin acetate group was significantly declined (P < 0.05). There was no statistically significant difference between Leuprolide acetate group and Goserelin acetate group (P > 0.05). (3) Pregnancy rate: the number of patients require fertility were 28 cases in laparoscopy group, 39 cases in Leuprolide acetate group and 35 cases in Goserelin acetate group. After 2 years follow up, pregnancy rate of 62% (24/39) in Leuprolide acetate group and 60% (21/35) in Goserelin acetate group were high than 39% (11/28) in laparoscopy group significantly, which did not reached significant difference (P > 0.05). (4) Adverse drug reaction:rates of a adverse reactions were 21% (15/70) in Leuprolide acetate group and 20% (13/66) in Goserelin acetate group, including irregular vaginal bleeding associated with low estrogen level. There was no significant difference in adverse reactions (P > 0.05).
  
  
  CONCLUSIONS
  Compared with laparoscopy alone, laparoscopy combined with GnRH-a is more effective in treatment of, which exhibit lower recurrence rate, higher pregnancy rate and fewer adverse reactions. Domestic Leuprolide acetate have similar safety and efficacy compared with imported GnRH-a.
