Hyaluronic Acid and Uterine Synechiae (HYFACO)

July 31, 2021 updated by: Assistance Publique - Hôpitaux de Paris

Non-stick Gel Applicated After Scraping Surgery for Natural Miscarriage and Uterine Synechiae Prevention

The primary purpose of the study is to compare efficiency of a non-stick gel application after scraping surgery for natural miscarriage with no non-stick gel application after scraping surgery.

Post-scraping uterine synechiae rate will be established at the diagnostical hysteroscopy 6-8 weeks after surgery.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Women patients coming for natural miscarriage will be compared according to whether a non-stick gel will be applicated or not after scraping surgery.

6-8 weeks after this surgery uterine synechiae rate will be established at a diagnostical hysteroscopy. Proofreading of this exam will be made by 2 experts at the end of the study without knowing the randomization arm.

Long-term follow-up of the patients will be performed to evaluate the effect of the non-stick gel application on post-surgical fertility at 6, 12, and 24 months after scraping surgery using questionnaire asked by post, mail or phone.

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

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
Evaluation of post-surgical uterine synechiae rate during a diagnostical hysteroscopy.
Time Frame: 6-8 weeks after scraping surgery
Diagnostical hysteroscopy performed 6-8 weeks after scraping surgery.
6-8 weeks after scraping surgery

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.

Time Frame
Evaluation of the effect of the non-stick gel application on the post-surgical fertility 6, 12, and 24 months after scraping surgery.
