Clinical Trial Summary

Hysterectomy is an effective treatment used as a first-line approach for uterine myomas. Several others alternatives to hysterectomy have been developed in recent years for women wishing to retain their uterus: myomectomy, radiological embolization, focused ultrasound.

Myomectomy, particularly through minimally invasive surgery, is currently considered the conservative treatment of choice for patients wishing to preserve their fertility. However, three important issues should be considered: the risk of intra- and postoperative bleeding, the risk for recurring myomas, and the preservation of subsequent fertility.

Preventive uterine artery occlusion can be combined with laparoscopic myomectomy in order to avoid bleeding and improve uterine suture. Another expected long-term benefit is the improvement of treatment efficacy, leading to less symptoms and myomas recurrence. However, the effect of uterine arteries occlusion on the ovarian reserve of women of childbearing age has not yet been studied, which limits its clinical application.

Description:

Objectives:

1. To assess the effect of preventive uterine artery occlusion during laparoscopic myomectomy on ovarian reserve parameters;

2. To evaluate the effect of preventive uterine artery occlusion during laparoscopic myomectomy on intra- and postoperative blood loss, operative time, clinical symptoms improvement, long-term recurrence of myomas and fertility.

Materials and methods:

Design: This is a prospective randomized single blind trial, including 60 women undergoing a laparoscopic myomectomy for symptomatic uterine myomas. Patients are randomized into two groups: a control group "myomectomy alone" and an experimental group "myomectomy with preventive uterine arteries occlusion".

Setting: The duration of the study will normally be 5 years and will take place at the University Hospitals of Geneva. The study will include about 20 women per year and follow-up will last 2 years. Inclusion criteria are: women of childbearing age, wishing to retain their uterus, having symptomatic uterine myomas and who are eligible for a laparoscopic myomectomy.

The parameters that will be intraoperatively evaluated are the operation time, blood loss and the complications of the surgical technique. Postoperative complications, improving clinical symptoms, myomas recurrence and fertility are discussed at short and long term follow-up.

The ovarian reserve will be evaluated pre- and postoperatively for each patient. It will be determined by plasmatic AMH (anti-Mullerian Hormone) and ultrasound antral follicle count. Women with undetectable preoperative plasmatic AMH will be excluded from the study. Plasmatic AMH and antral follicle count will be measured at 1, 3, 6, 12 and 24 months during the postoperative follow-up.

Limitations:

The sample size is calculated in order to demonstrate a significant difference in plasmatic AMH before and after myomectomy. Small differences are not highlighted in this study, but they probably would not have any impact in clinical practice.

Impact of the study:

The results of this study could have a real impact on daily surgical practice. In case of persistent alteration of ovarian reserve in the experimental group compared to the control group, preventive uterine arteries occlusion during a laparoscopic myomectomy should only be indicated in patients who do not wish pregnancy. If there is no significant impact on ovarian reserve and a beneficial effect on reducing intraoperative blood loss and long-term improvement of symptoms, it should be systematically proposed in all patients undergoing a laparoscopic myomectomy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Evolution of ovarian reserve markers after myomectomy	It will be determined by plasmatic AMH and ultrasound antral follicle count	Evaluation of the ovarian reserve at several times: on preoperative, 1, 3, 6, 12 and 24 months postoperative
Secondary	Intra-and post-operative blood loss	Blood loss will be estimated during the operation, and will be followed for the duration of hospital stay, an expected average of 3 days. furthermore, we will dose the hemoglobin before and after the intervention.	peroperative
Secondary	operative time	Time needed to realise the intervention from the incision to the cutaneous stitches	peroperative
Secondary	peroperative complications	it will be noticed the conversion in laparotomy, the blood transfusion, the organic and vessels lesions	peroperative
Secondary	Clinical symptoms improvement: hypermenorrhea	Evaluation of quantity of blood during menstruation with the PBAC scale (Pictorial Blood Assessment Chart) before and after the intervention	1, 3, 6, 12 and 24 months postoperative
Secondary	Clinical symptoms improvement: dysmenorrhea	Evaluation of improvement of dysmenorrhea by asking patients the pain they have from 0 to 10 and their consumption of pain killers (NSAIDs and paracetamol) during menstruation.	1, 3, 6, 12 and 24 months postoperative
Secondary	Clinical symptoms improvement: occuring of pregnancy	Evaluation of the occurence of pregnancy by asking women the number of pregnancy, of miscarriage, of abortion, of term pregnancy since the intervention	12 and 24 months postoperative
Secondary	long-term recurrence of myomas	An US will be made at 1, 3, 6, 12 and 24 months to estimate the recidive of myoma. It will be considered a recidive when the myoma will be bigger than 20 mm	2 years
