      Abstract

      Objective

      To compare the usefulness of vaginal danazol and diphereline in the management of intra-operative bleeding during hysteroscopy.

      Design

      Randomized controlled clinical trial.

      Setting

      University hospital.

      Patients

      One hundred and ninety participants of reproductive age were enrolled for operative hysteroscopy. Thirty women were excluded from the study.

      Interventions

      One hundred and sixty participants with submucous myomas were allocated at random to receive either vaginal danazol (200 mg BID, 30 days before surgery) or intramuscular diphereline (twice with a 28-day interval).

      Main outcome measures

      Severity of intra-operative bleeding, clarity of the visual field, volume of media, operative time, success rate for completion of operation and postoperative complications.

      Results

      Overall, 145 patients completed the study. In the danazol group, 78.1% of patients experienced no intra-operative uterine bleeding, and 21.9% experienced mild bleeding. In the diphereline group, 19.4% of patients experienced no intra-operative uterine bleeding, but mild, moderate and severe bleeding was observed in 31.9%, 45.8% and 2.8% of patients, respectively. The difference between the groups was significant (p < 0.001). A clear visual field was reported more frequently in the danazol group compared with the diphereline group (98.6% vs 29.2%, p < 0.001). The mean operative time was 10.9 min and 10.6 min in the danazol and diphereline groups, respectively (p = 0.79). The mean volume of infused media was 2.0 L in both groups (p = 0.99). The success rate was 100% for both groups with no intra-operative complications.

      Conclusion

      Both vaginal danazol and diphereline were effective in controlling uterine bleeding during operative hysteroscopy. However, vaginal danazol provided a clearer visual field.
