    Abstract:
    OBJECTIVE: To compare the usefulness of preoperative treatment with triptorelin, letrozole or ulipristal acetate or no treatment before hysteroscopic removal of uterine submucosal myomas. STUDY DESIGN: Single center prospective non-randomized comparative pilot study. The study included consecutive premenopausal patients undergoing hysteroscopic resection of myomas graded as type 0, type 1 or type 2 according to the FIGO classification with diameter between 20 and 35 mm. Exclusion criteria were: associated polyps, associated non-hysteroscopic surgical procedures, >2 myomas requiring hysteroscopic resection. This study enrolled patients who underwent either direct surgery (group S; n=23) or 3-month preoperative treatment with triptorelin (3.75 mg every 28 days; group T; n=20), letrozole (2.5 mg/day; group L; n=11) or ulipristal acetate (5 mg/day; group U; n=7). Patients underwent hysteroscopic resection of the myomas. RESULTS: All medical treatments caused a significant decrease in the volume of myomas (group T, p<.001; group L, p<.001; group U, p=.006); however, the percentage decrease in myoma volume was lower in group U than in group T (p=.001) and in group L (p=.010). The hysteroscopy time was higher in group S than in group T (p<.001) and in group L (p=.001); there was no significant difference in the hysteroscopy time between group S and group U (p=.206). Fluid absorption was lower in group T than in group S (p=.002) and in group L than in group S (p=.048); fluid absorption was similar in group S and group U (p=.110). Intra- and postoperative complications, postoperative pain, and patient satisfaction were similar in the four study groups. Surgeon's evaluation of operative difficulty was better in group T than in group S (p<.005). CONCLUSIONS: Preoperative treatment with triptorelin and letrozole decreases the hysteroscopy time and the volume of fluid absorbed during hysteroscopic resection of uterine submucosal myomas.
