title: Pregnancy rates after laparoscopic treatment. Differences related to tubal status and presence of endometriosis.
abstract: OBJECTIVE
  To examine how preexisting tubal adhesions and endometriosis affect pregnancy outcome after laparoscopic treatment in infertile women with no apparent causes of infertility other than tubal factors.
  
  
  METHODS
  Pregnancy outcomes in 186 infertile women for a follow-up period of 18 months after laparoscopy were analyzed. Laparoscopic manipulations consisted of adhesiolysis of tubes and removal of endometriotic lesions.
  
  
  RESULTS
  The patients were classified into three groups, those with no tubal adhesions (group A, n = 83), unilateral tubal adhesions (group B, n = 46) and bilateral tubal adhesions with at least one tube patent (group C, n = 57). The cumulative pregnancy rate in group C (13.2%) was lower than in groups A (41.8%) and B (45.7%) 18 months after laparoscopy. The average time to conception in group A (6.7 +/- 0.8 months) tended to be shorter than that in group B (10.6 +/- 1.2 months). In group A, pregnancy rates were essentially the same between minimal/mild endometriosis and moderate/severe endometriosis. Regarding group B, women with minimal/mild endometriosis exhibited significantly higher pregnancy rates than those with moderate/severe endometriosis, while pregnancy rates in women without endometriosis fell in between.
  
  
  CONCLUSIONS
  Pregnancy rates after laparoscopic treatment are different in relation to tubal status and the presence of endometriosis.
