This multicenter study evaluated endometrioma recurrence after conservative laparoscopic excision followed by long-term oral contraceptive therapy, comparing three progestins (desogestrel, gestodene, dienogest) in a randomized design and including an observational control group of women who refused postoperative hormonal therapy. Among 168 women, 21/131 (12.5%) had endometrioma recurrence over 24 months, and recurrence was significantly higher in non-users than in women receiving long-term OCs. Differences between the three progestin groups were not statistically significant, and the authors excluded women with ultrasound persistence of endometrioma at 1 month from the analysis, which may limit generalizability to early non-response. This paper is centrally about endometriosis — it examines how different oral contraceptive progestins affect ovarian endometrioma recurrence prevention after laparoscopic excision.

Abstract

Objective The primary aim of the study was to analyze the endometrioma recurrence rate in patients who underwent laparoscopic excision followed by postoperative long-term regimen of oral contraceptives (OCs).

Materials and methods

168 patients who underwent a conservative laparoscopic surgery for endometrioma, during the period between September 2009 and August 2010 in three university hospitals were studied. A long-term OCs therapy was offered to all women following surgery. Patients were randomly divided into three groups according to different progestins used (desogestrel, gestodene, dienogest). Women who refused a postoperative hormonal therapy served as control. Follow-up visits and transvaginal scan were planned at 1, 3, 6, 12, and 24 months after surgery. All patients who showed an ultrasound persistence of the endometrioma at 1 month follow-up were excluded from clinical analysis.

Results

Of the 168 patients, 131 completed the 24 months follow-up. Endometrioma recurrence was found in 21 (12.5 %) of all patients, it was unilateral in 17 cases while bilateral in 4 cases. The rate of recurrent endometrioma was statistically significant in non-users compared to the long-term OCs treated patients.

Conclusion

The current data suggest the usefulness of long-term OCs regimen after conservative surgery for the prevention of ovarian endometrioma recurrence. As a statistical significant difference could not be observed between OCs groups, further study on the individual molecules is required in order to really understand the effect of each of them.
