title: [Clinical effect on women with different types of endometriosis related infertility treated by conservative surgery].
abstract: OBJECTIVE
  To study pregnancy outcome and recurrence in patients with different type of endometriosis related infertility treated by conservative surgery.
  
  
  METHODS
  From January 2005 to December 2010, 79 patients with endometriosis related infertility underwent conservative laparoscopic surgery in Peking University First Hospital, including 16 cases with deep infiltrating endometriosis, 39 cases with ovarian endometriosis and 24 cases with peritoneal endometriosis. At 1 to 5 years follow-up after surgery, natural pregnancy outcome and recurrence were studied.
  
  
  RESULTS
  (1) The accumulated pregnancy rate were 6/16 in deep infiltrating endometriosis group, 36% (14/39) in ovarian endometriosis group, and 46% (11/24) in peritoneal endometriosis group, which did not reached statistical difference (P > 0.05). (2) The median interval between pregnancy and surgery were 38.5 months in deep infiltrating endometriosis group, 9.5 in ovarian endometriosis group and 6.0 months in peritoneal endometriosis group. The median interval in deep infiltrating endometriosis was significantly longer than that in peritoneal endometriosis group and ovarian endometriosis group (P < 0.01). Total of 11 patients in peritoneal endometriosis group and 11 patients in ovarian endometriosis group acquired pregnancy at 18 months after surgery. (3) The recurrent rate were 5/16 in deep infiltrating endometriosis group, 13% (5/39) in ovarian endometriosis group and 4% (1/24) peritoneal endometriosis group, respectively (P > 0.05).
  
  
  CONCLUSIONS
  There was no difference among these three groups in accumulated pregnancy rate. However, the interval between pregnancy and surgery was significantly longer in patients with deep infiltrating endometriosis when compared with those in the other groups.
