Impact on Ovarian Reserve of Second Laparoscopic Surgery for Recurrent Unilateral Endometriomas: a Case-control Study.

This retrospective case-control study was performed in an Academic centre for the diagnosis and treatment of endometriosis. It included patients with recurrent unilateral endometriomas who were previously operated for the same condition (cases) and patients without recurrency who previously underwent surgery for unilateral endometrioma (controls). The primary outcome of the study was to assess the impact on ovarian reserve of second surgery for recurrent unilateral endometriomas. The evaluation of ovarian reserve was performed by assessing serum anti-mullerian hormone (AMH) level, serum follicle-stimulating hormone (FSH) level, 17-beta estradiol level and antral follicle count (AFC).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 50 years (ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

In this study were recruited women referred to an academic centre for the diagnosis and treatment of endometriosis.

Cases were patients undergoing second surgery for recurrent unilateral endometrioma.

Controls were patients previously operated for unilateral endometrioma.

Description

Inclusion Criteria:

  • reproductive age (at the time of both surgical procedures);
  • two surgical procedures on the same ovary (stripping of endometrioma with
  • largest diameter ≥ 4 cm; cases) performed at our Institution;
  • one surgical procedures (stripping of endometrioma with largest diameter ≥ 4 cm; controls) performed at our Institution;
  • histological diagnosis of ovarian endometriomas;
  • complete assessment of ovarian reserve at routinary follow-up at our institution.

Exclusion Criteria:

  • patients aged ≥ 40 years at the time of primary surgery;
  • surgical procedures on the contralateral ovary (at primary or second-line surgery);
  • previous salpingectomy or hysterectomy;
  • unilateral ovariectomy at the time of first or second surgery;
  • ultrasonographic diagnosis of persistent endometrioma after first surgery;
  • additional surgical procedures for endometriomas or for other ovarian diseases before first surgery and between first and second surgery;
  • hormonal treatment within 3 months from ovarian reserve assessment;
  • patients followed-up < 3 months after second-line surgery (for cases).
  • pregnancy and/or breastfeeding during the study period.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Anti-mullerian hormone (AMH) level.
Time Frame: In cases, anti-mullerian hormone (AMH) level was determined 3 months after second laparoscopic surgery. In controls, AMH levels was determined in the the fertility assessment performed during follow-up (matched to the correspondent case).
In cases, anti-mullerian hormone (AMH) level was determined 3 months after second laparoscopic surgery. In controls, AMH levels was determined in the the fertility assessment performed during follow-up (matched to the correspondent case).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Follicle-stimulating hormone (FSH) level.
Time Frame: In cases, follicle-stimulating hormone (FSH) level was determined 3 months after second laparoscopic surgery. In controls, FSH levels was determined in the the fertility assessment performed during follow-up (matched to the correspondent case).
In cases, follicle-stimulating hormone (FSH) level was determined 3 months after second laparoscopic surgery. In controls, FSH levels was determined in the the fertility assessment performed during follow-up (matched to the correspondent case).
17-beta estradiol level.
Time Frame: In cases, 17-beta estradiol level was determined 3 months after second laparoscopic surgery. In controls, 17-beta estradiol level was determined in the the fertility assessment performed during follow-up (matched to the correspondent case).
In cases, 17-beta estradiol level was determined 3 months after second laparoscopic surgery. In controls, 17-beta estradiol level was determined in the the fertility assessment performed during follow-up (matched to the correspondent case).
Antral follicle count (AFC).
Time Frame: In cases, antral follicle count (AFC) was determined 3 months after second laparoscopic surgery. In controls, antral follicle count was determined in the the fertility assessment performed during follow-up (matched to the correspondent case).
In cases, antral follicle count (AFC) was determined 3 months after second laparoscopic surgery. In controls, antral follicle count was determined in the the fertility assessment performed during follow-up (matched to the correspondent case).

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
