Results of laparoscopic treatments of ovarian endometriomas: laparoscopic ovarian fenestration and coagulation

Objective: To determine the long-term results of laparoscopic fenestration and coagulation of ovarian endometriomas and to compare them with the results of ovarian cystectomy performed by either laparotomy or laparoscopy. Design: Case-control study. Setting: Two university-affiliated hospitals. Patient(s): One hundred fifty-six premenopausal women with ovarian endometriomas of at least 3 cm in diameter (stage 3 and 4 endometriosis, revised American Fertility Society classification). Intervention(s): Laparoscopic ovarian fenestration and coagulation (group 1, 80 patients); laparoscopic ovarian cystectomy (group 2, 23 patients); and ovarian cystectomy by laparotomy and microsurgical technique (group 3, 53 patients). Main Outcome Measure(s): Operative findings, recurrence rate, and cumulative clinical pregnancy rate (PR) over a 36-month follow-up period. Result(s): The mean (+/- SD) time to first pregnancy was significantly shorter in group 1 (1.4 +/- 0.2 years) than in group 2 (2.2 +/- 0.5 years) or group 3 (2.4 +/- 0.5 years). The difference between the cumulative clinical PR between the three groups was not statistically significant after 36 months of follow-up. The difference in the recurrence rate among groups 1, 2, and 3 was not statistically significant. Conclusion(s): Laparoscopic ovarian fenestration and coagulation of endometriomas leads to faster conception than ovarian cystectomy by laparotomy. Laparoscopic ovarian fenestration and coagulation of endometriomas is associated with cumulative clinical PRs and recurrence rates over 36 months that are similar to those associated with ovarian cystectomy.
