Ulipristal Acetate Before High Complexity Hysteroscopic Myomectomy: A Retrospective Comparative Study.

STUDY

OBJECTIVE

To evaluate the efficacy of preoperative treatment with ulipristal acetate (UPA) in patients undergoing high complexity hysteroscopic myomectomy.

DESIGN

Retrospective analysis of a prospectively collected database (Canadian Task Force classification II-2).

SETTING

University teaching hospital.

PATIENTS: Patients of reproductive age requiring hysteroscopic myomectomy with STEPW (size, topography, extension, penetration, and wall) score 5 or 6.

INTERVENTIONS: Patients included in the study either underwent direct surgery (group S) or received a 3-month preoperative treatment with UPA (group UPA). Based on a power calculation, 25 patients were required in each study group.

MEASUREMENTS AND MAIN

RESULTS

Myoma characteristics were similar in the 2 study groups. The 3-month UPA treatment caused a 21.9% (±10.3%) mean (±SD) percentage decrease in myoma volume. The number of complete resections (primary outcome of the study) was higher in group UPA (92.0%) than in group S (68.0%; p = .034). The operative time was lower in group UPA than in group S (p = .048), whereas there was no significant difference in fluid balance between the 2 study groups (p = .256). The incidence of complications was similar in the 2 groups (p = .609). Patient satisfaction at 3 months from surgery was higher in group UPA than in group S (p = .041).

CONCLUSION

A 3-month preoperative treatment with UPA increases the possibility of complete resection in high complexity hysteroscopic myomectomy. It decreases the operative time and improves patient satisfaction at 3 months from surgery.
