Comparison of laparoscopic presacral neurectomy and laparoscopic uterine nerve ablation for primary dysmenorrhea.

OBJECTIVE: To compare laparoscopic presacral neurectomy and laparoscopic uterine nerve ablation for primary dysmenorrhea.

STUDY DESIGN: Sixty-eight patients with primary dysmenorrhea and a poor response to medical treatment were randomized into two groups. One group (33 patients) had laparoscopic presacral neurectomy (LPSN) and the other group (35 patients), laparoscopic uterine nerve ablation (LUNA).

RESULTS: There were no complications, and all the patients left the hospital within 24 hours after surgery. The efficacy of both surgical methods was almost equal (87.9% vs. 82.9%) at the 3-month postoperative follow-up visit, but the efficacy of LPSN was significantly better than that of LUNA (81.8% vs 51.4%) at the 12-month visit.

CONCLUSION: LPSN is a valid option for treating primary dysmenorrhea.
