title: Comparison of CO2 laser laparoscopy with laparotomy for treatment of endometriomata.
abstract: OBJECTIVE
  To assess the effectiveness of laparoscopy versus laparotomy in the treatment of endometriomata.
  
  
  METHODS
  Controlled study using data prospectively tabulated.
  
  
  METHODS
  Treatment performed by senior author in a referral reproductive endocrinology and surgery private practice.
  
  
  METHODS
  One hundred infertile women were diagnosed with endometriomata.
  
  
  METHODS
  Forty-eight women were treated with CO2 laser laparoscopy (laparoscopy group) and 52 women were treated with CO2 laser or nonlaser laparotomy (laparotomy group).
  
  
  METHODS
  The hypothesis that laparoscopy group pregnancy rates (PRs) would be equal to or greater than laparotomy group was formulated before data analysis but after data tabulation.
  
  
  RESULTS
  The 1 and 3-year life table estimated cumulative PRs +/- SE were 0.30 +/- 0.07 and 0.52 +/- 0.09 for laparoscopy group and 0.23 +/- 0.06 and 0.46 +/- 0.09 for laparotomy group (Breslow P = 0.48). Monthly fecundity over 3 years was 2.4% for laparoscopy group and 2.0% for laparotomy group.
  
  
  CONCLUSIONS
  Laparoscopy with CO2 laser can be a safe and effective modality for treating endometriomata.
