Patients will be prescribed Ulipristal acetate 5mg daily for 12 weeks before operation. If the patients have anaemia with haemoglobin less than 10g/dL, ferrous sulphate 300mg three times a day will be prescribed as well. Tranexamic Acid 500mg four times a day will be prescribed on request basis.

Patients will be prescribed placebo pills daily for 12 weeks before operation. If the patients have anaemia with haemoglobin less than 10g/dL, ferrous sulphate 300mg three times a day will be prescribed as well. Tranexamic Acid 500mg four times a day will be prescribed on request basis.

Uterine leiomyomas is the commonest benign tumour of the female genital tract. It lead to menorrhagia, anaemia, pain and pressure symptoms. Due to the enlarged uterus, the use of minimal invasive surgery is limited. There is also increase risk of intraoperative blood transfusion. Ulipristal acetate (UPA) is a selective progesterone-receptor modulator (SPRM). Preoperative use of Ulipristal for 12 weeks has been shown to decrease uterine bleeding, fibroid volume, pre-operative anaemia and symptoms severity. However there is still lacking evidence in terms of long term safety and efficacy, especially in Chinese population. The aim of the present study is to evaluate the effect and safety on preoperative use of Ulipristal on fibroid.

Uterine leiomyomas is the commonest benign tumour of the female genital tract. It is often asymptomatic, but can also lead to anaemia, pain and pressure symptoms. It is the commonest indication for hysterectomy, especially abdominal hysterectomy. Currently, the use of hormonal treatment is associated with side effects including gastrointestinal upset, bloating, weight gain and thromboembolic risks. The main stay for treatment relies on surgery.

Furthermore, the use of minimal invasive surgeries is limited by the size of the fibroids. Preoperative use of Gonadotrophic Releasing Hormone analogues (GnRHa) is effective in shrinkage of the uterine leiomyomas and reduction of uterine bleeding. However, postmenopausal symptoms including hot flushes, vaginal dryness are profound.

Ulipristal acetate (UPA), previously named CDB-2914, is a selective progesterone-receptor modulator (SPRM). It binds to the progesterone receptors with high affinity. It inhibits follicular development and ovulation, while it has no significant effects on estradiol levels and antiglucocorticoid activity. Preoperative use of Ulipristal for symptomatic uterine fibroids has been investigated in randomized controlled study with improvement in terms of uterine bleeding, fibroids volume, pre-operative anaemia and symptoms severity. However there is still lacking evidence in terms of long term safety and efficacy. Also there is lack of evidence in Chinese population.

The aim of the present study is to evaluate the effect and safety on preoperative use of Ulipristal on fibroid.

Pictorial bleeding assessment chart will be used for assessment of uterine bleeding. Patients will be assessed before the start of treatment, after completion of 6 weeks course and after completion of 12 weeks course. The change of uterine bleeding after completion of 12 weeks course of treatment will be recorded.

The change of haemoglobin level after completion of 12 weeks course will be recorded.

The fibroid volume will be measured using ultrasonography before start of treatment, after 6 weeks course of treatment and after completion of 12 weeks course of treatment.

The amount of blood loss at hysterectomy will be recorded.

2 weeks before scheduled operation, patients will be assessed by the operation team and the most suitable route of hysterectomy will be discussed again. The possibility of conversion to less invasive intervention options including from laparotomy to laparoscopy will be recorded.

The side effects including nausea, vomiting, headache, dyspepsia will be recorded.

Presence of malignancy or hyperplasia in the operative specimen will be recorded.
