OBJECTIVE: To evaluate and compare the effectiveness of oral and vaginal misoprostol versus placebo to facilitate office hysteroscopy without anesthesia during infertile diagnostic evaluation. DESIGN: Randomized, prospective trial. SETTING:Patients scheduled for diagnostic office hysteroscopy at a university hospital. PATIENT(S): Seventy-five infertile patients scheduled for diagnostic office hysteroscopy. INTERVENTION(S): Patients were divided into three groups: group A received oral misoprostol 600 μg; group B, vaginal misoprostol 400 μg; and group C, oral placebo. MAIN OUTCOME MEASURE(S): Pain, evaluated by visual analogue scale, and surgical time were recorded and compared. Statistical analysis was done using Student's t-test. RESULT(S): Pain was low in the vaginal misoprostol group. Mean visual analogue scale in the oral misoprostol group was 6.04 ± 1.5; in the vaginal misoprostol group 2.85 ± 1.2; and in the placebo group 7.50 ± 1.5. Procedural time for office hysteroscopy was shorter in the vaginal misoprostol group (2.7 ± 1.0 minutes) compared with group A (5.5 ± 1.1 minutes) and group C (6.3 ± 3.8 minutes). CONCLUSION(S): Vaginal misoprostol, 400 μg, administered the day before office hysteroscopy considerably reduces pain and the time needed for hysteroscopy. This simple strategy may facilitate office hysteroscopy during an infertility work-up.
