title: [Predictive factors for recurrence of ovarian endometrioma after laparoscopic excision].
abstract: OBJECTIVE
  To analyze the factors that might influence the recurrence of ovarian endometriomas after laparoscopic excision.
  
  
  METHODS
  A retrospective cohort study. We evaluated 129 patients who underwent laparoscopic excision of ovarian endometriomas from 2003 to 2012 and who were followed up for at least two years after surgery. Vaginal ultrasound was repeated to exclude persistent lesion and to identify recurrence. The Student's t-test was used to compare continuous variables and the χ2 or Fischer exact test (for values of less than five) was used to test homogeneity between proportions. A logistic regression model for multivariate proportional hazards was used to analyze predictors of long-term outcome. The level of significance was set at 5% in all analyses.
  
  
  RESULTS
  The overall rate of ovarian endometrioma recurrence was 18.6%. Endometrioma diameter, surgical procedure techniques and demographic data such as age, presenting symptoms, body mass index, smoking and physical exercise habits were not associated with recurrence, whereas interruption of postoperative medical treatment was significantly correlated with a higher recurrence rate (OR 23.7; 95%CI 5.26-107.05; p=0.001).
  
  
  CONCLUSIONS
  Current oral contraceptive use appears to be associated with a dramatic reduction in the risk of recurrence of ovarian endometriotic cysts. Treatment interruption was associated with a higher recurrence rate of ovarian endometrioma after laparoscopic treatment.
