Effectiveness of bipolar impedance controlled radiofrequency (NovaSure) endometrial ablation for the treatment of menorrhagia in Hong Kong Chinese women.

Objective: Bipolar impedance controlled radiofrequency endometrial ablation is a valuable treatment options for menorrhagia. We examined the short term outcomes of Hong Kong Chinese women undergone this procedure.

Material: All patients who underwent this procedure at Queen Elizabeth Hospital, Hong Kong during January 2013 to August 2016. Method this is a prospective cohort study where the menstruation status among the selected patients was questioned at each 6 monthly follow-up after the procedure. A validated MIQ (menorrhagia impact questionnaire) was sent to assess quality of life before and after the procedure.

Result: 44 patients underwent the procedure. 77.4% had reduced or minimal bleeding with 19.4% achieving amenorrhoea. 96.77% were found to have reduced bleeding or amenorrhoeic at 3 months; 96.3% at 6 months, 95.83% at 12 months; 95.45% at 18 months; 100% at 24 and 36 months of follow up. Endometritis occurred in 9.7%. No case required blood transfusion or other surgical management post-operatively. Improvement in all aspects of MIQ was seen when compared post-operative scores to preoperative scores (p < 0.01). 100% claimed improvement in menstruation and 87.1% suggested they would recommend the procedure to family and friends.

Conclusions: Bipolar impedance controlled radiofrequency endometrial ablation appears to be an effective method for managing menorrhagia amongst Chinese women in Hong Kong.
