Preoperative administration of an estradiol valerate and dienogest oral contraceptive improved endometrial patterns, reduced operating time, decreased surgical difficulty, and lowered pain scores during office operative hysteroscopy compared to controls.

Abstract

To investigate the impact of a 3 months preoperative administration of an oral contraceptive, containing dienogest (DNG) and estradiol valerate (E₂V) on the outcome of office operative hysteroscopy (OOH). One-hundred and forty-two patients diagnosed at office hysteroscopy as having an asynchronous endometrium associated with either a broad-base sessile endometrial polyp (>1.5, 1/3 uterine cavity) or scheduled for tubal sterilization were enrolled into a prospective case-control study at University "Federico II" of Naples. 86/142 patients accepted the preoperative hormonal treatment (Group A), while 56/142 refused, thus becoming controls (Group B). Group A underwent OOH during the 10th-20th days of the third cycle of treatment. In Group B OOH was performed at enrolment, together with the diagnostic procedure. The study outcomes were: endometrial pattern, success rate, operating time, degree of surgical difficulty and pain score. An overall improvement of the endometrium was reported in 100% of cases in Group A. A statistically significant difference in success rate could not be demonstrated between two groups. Operative procedures were performed significantly quicker and easier in Group A than Group B (p < 0.001 and p < 0.05, respectively). The mean Visual Analog Scale (VAS) score was significantly lower in Group A (p < 0.001). A short pretreatment with combined oral contraceptive (COC) containing E₂V/DNG seems to have a favorable impact on endometrium which in turn may result in an improvement of the overall outcomes of OOH.
