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.

Detailed Description

Primary endpoints

• Assess the volume of blood loss

Secondary endpoints

  • Compare the rates of intra- and postoperative complications, the necessity of blood transfusion, length of surgery, length of hospital and ICU stay, and leiomyoma symptoms relief
  • Determine the procedure impact on fertility by evaluating the level of anti-mullerian hormone, pregnancy rates, pregnancy complications, and the way of delivery

Patients who meet study inclusion criteria will be randomized into one of two treatment arms: 1) laparoscopic myomectomy preceded by temporary uterine blood supply occlusion or 2) laparoscopic myomectomy with a conventional approach.

Sixty patients will undergo laparoscopic myomectomy preceded by temporary uterine blood supply occlusion performed by gynecologists at Mother and Child Clinic Saint-Petersburg and other institutions participating in the study. Sixty patients will undergo conventional laparoscopic myomectomy performed by gynecologists at Mother and Child Clinic Saint-Petersburg and other institutions participating in the study.

Patients eligible for inclusion, after signing an informed voluntary consent to participate in the study, will be randomized in a 1:1 ratio to the treatment groups using stratification by age, size, and leiomyoma nodes location.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

  • Single or multiple nodes
  • Absent contraindications for laparoscopic myomectomy
  • Voluntarily signed informed consent to participate in the study

Exclusion Criteria:

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
Measure Description
Time Frame
Blood loss
Time Frame: At the end of the intervention
Evaluation of blood loss volume
At the end of the intervention

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
Measure Description
Time Frame
