About this study

This is a prospective, multicentric (two centers: 1:San Raffaele Scientific institute, Milan, Italy; 2:Jagiellonian University, Collegium Medicum, Cracow, Poland), randomized (1:1) clinical trial that includes patients undergoing surgery for primary unilateral or bilateral symptomatic endometriomas.

The aim of the study is to determine whether and to what extent the two surgical procedures for endometrioma, cystectomy and laser vaporization, affect ovarian reserve. Recently, cystectomy has been questioned as an ideal surgical approach because it may involve excessive removal of ovarian tissue and the loss of follicles; laser vaporization has been proposed as a promising method to preserve ovarian function.

Read the detailed description

Excisional surgery is the recommended treatment for ovarian endometrioma because of higher pregnancy rate and lower recurrence rate compared with ablative techniques. From the standpoint of ovarian reserve, the efficiency of cystectomy remains a topic of considerable debate: in recent years, cystectomy has been questioned as an ideal surgical approach for endometriomas because it is associated with excessive removal of ovarian tissue and loss of ovarian follicles with subsequent reduction of ovarian reserve. According to a recent report, absence of follicular growth was observed in 13% of operated ovaries, although this event never occurred in the contralateral gonad.

In San Raffaele Scientific Institute, fear of ovarian failure after cystectomy resulted in the introduction of an ablative technique involving CO2 laser technology, which posses the ability to deliver energy with little thermal spread. More than 80 patients were treated with CO2 laser at this Institution during three-year experience. This surgical procedure was inspired by the one employed by Jacques Donnez for more than 20 years, in which CO2 laser is used to ablate endometriomas' inner wall, after 3-months GnRHa therapy. Laser vaporization, according to the ''three-step procedure", has also been proposed as the best method to preserve ovarian function; moreover, reassuring data on the rate of long-term recurrence after laser vaporization have recently been published.

However, no data are available about the single use of CO2 laser fiber vaporization (without GnRHa therapy) with respect to the ovarian reserve.

Since 2015, the investigators have continuously evaluated the benefits of CO2 laser vaporization through a clinical trial assessing the postoperative changes in ovarian reserve as indicated by antral follicle count (AFC) and anti-mullerian hormone (AMH); the results of this pilot study support the positive effects of CO2 laser on ovarian reserve as demonstrated by higher AFC and no change in AMH at 3-month follow-up. In order to provide more conclusive data about the potential advantage of CO2 laser ablation with respect to ovarian cystectomy in terms of fertility outcomes a prospective randomized trial has been planned; the aim of this prospective randomized study is to determine whether and to what extent the two surgical procedures for ovarian endometrioma (cystectomy versus C02 laser vaporization) affect ovarian reserve.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • stripping techniqueProcedure or surgery

    The cyst is stripped from the healthy ovary by traction and countertraction; after the removal of the cyst, hemostasis is achieved by selective bipolar coagulation.

  • CO2 laser (AcuPulse Duo, Lumenis)Device

    The cyst content is drained and the internal wall is vaporized with CO2 laser beam (AcuPulse Duo, Lumenis, Israel)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. changes in antral follicle count (AFC)

    number of follicles with average diameter of 2-10 mm in both ovaries assessed on the second and fifth day of the menstrual cycle

    Measured: baseline and 3 months

Secondary outcomes (1)
  1. changes in serum antimullerian hormone (AMH) levels

    AMH is assessed on venous blood samples (Beckman-Coulter 2nd-generation; Gen II) obtained on day 2-5 of the menstrual cycle

    Measured: baseline and 3 months

Questions about this trial

What is this clinical trial studying?

A study testing stripping technique and CO2 laser (AcuPulse Duo, Lumenis) in people with Endometrioma, run by Scientific Institute San Raffaele at 2 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 24 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Italy, Poland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

How can a doctor refer a patient or contact the research team?

Contact Jessica Ottolina, MD (ottolina.jessica@hsr.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

changes in antral follicle count (AFC) (time frame: baseline and 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03227640, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2017.
