title: [Analysis of relative factors influencing recurrence of endometriosis after operation treatment].
abstract: OBJECTIVE
  To explore the relative factors influencing the recurrence of endometriosis.
  
  
  METHODS
  Three hundred and fifty-six patients of endometriosis were treated with surgery and then followed up for 3 years. Seventy-five recurrent cases among them were analyzed retrospectively.
  
  
  RESULTS
  The recurrent rate was different in the <or= 24 year age group (chi(2) = 11.212, P < 0.05), while there was no difference in the other age groups. According to pathological type, the recurrent rate of mixed pattern (29.2%) was significantly higher than that of the simple chocolate cyst (17.5%; chi(2) = 4.622, P < 0.05). The higher the clinical stage of the endometriosis, the higher the recurrent rate (P < 0.05). The recurrent rate of endometriosis in the third stage was different between laparoscopy and laparotomy (31.3% vs 11.3%; chi(2) = 7.971, P < 0.01). Mifepristone could prolong the interval of recurrence after operation [(13 +/- 4) vs (7 +/- 3) months; t = 4.575, P < 0.01].
  
  
  CONCLUSIONS
  Individualized therapeutic regimen should be made in treatment of endometriosis according to age, pathological type, and clinical stage. The recurrent rate could be reduced and the interval of recurrence could be prolonged using ovarian function inhibiting drugs for a short time post-operation.
