Objective:
To compare the laparoscopic excision of primary versus recurrent ovarian endometriomas.
Design:
Descriptive study.
Setting:
Tertiary referral center for the treatment of endometriosis.
Patient(S):
Between 1993 and 2002, 359 consecutive patients: 305 primary surgeries (group A) and 54 reoperations for a recurrent endometrioma in the same ovary of the primary cyst (group B).
Intervention(S):
Laparoscopic stripping of the cyst wall. Follow-up evaluations every 6 months, including clinical and ultrasonographic evaluations and a questionnaire for pain symptoms (mean follow-up time, +/- standard deviation: 35.4 +/- 27.6 months).
Main Outcome Measure(S):
Recurrence of pain symptoms, sonographic recurrence of endometriomas, need for a new medical or surgical treatment, and reproductive outcome.
Result(S):
In groups A and B, respectively, the 5-year cumulative rates were not statistically significantly different: pain recurrence 20.5% versus 17.4%; ultrasonographic recurrence 18.9% versus 15.1%; retreatment requirement 19.4% versus 17.3%; and pregnancy 40.8% versus 32.4%. Although the difference was not statistically significant, compared with patients of group A, the women of group B underwent assisted reproduction techniques more frequently (50% vs. 32.2%) and had more irregular menstrual cycles associated with follicle-stimulating hormone levels > or = 14 IU/mL in the early follicular phase (5.5% vs. 1.3%).
Conclusion(S):
After laparoscopic excision of recurrent ovarian endometriomas, the recurrence of pain and the reproductive outcome are comparable with those found after primary surgery.
