Detailed Description

Intrauterine adhesion, also known as Asherman's syndrome, is the partial or complete occlusion of the uterine cavity as a result of endometrium damage. Most intrauterine adhesions patients manifest amenorrhea, reduced menstrual pattern, infertility, and intrauterine growth restriction, which seriously affect their reproductive health.It is well established that the formation of intrauterine adhesion likely involves hypoxia, reduced neovascularization, and altered expression of adhesion associated cytokines, but the exact mechanisms are not well understood. Although excessive curettage is considered the primary cause, intrauterine adhesion is known to be associated with diverse non-traumatic factors, such as postabortal sepsis, puerperal sepsis and infections. Intrauterine adhesion separation surgery is the gold standard for the treatment of uterine adhesion. Although the success rate is as high as 95%, the patients with moderate or severe uterine adhesion have severe damage to the endometrial basement, poor regeneration of endometrial and gland, poor tolerance of endometrial and poor clinical prognosis. Even if all kinds of anti-adhesion measures are used comprehensively, the postoperative recurrence rate of patients with moderate and severe uterine adhesion is high.Therefore this study was conducted to investigate whether intrauterine lavage or intrauterine gel-injection therapy after surgery could reduce the recurrence of intrauterine adhesion, promote the endometrial growth and repair and improve the menstruation and reproductive prognosis for severe intrauterine adhesion, and we hypothesize that intrauterine adhesion may be related to changes in microbial flora in the reproductive tract.

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

20 years to 45 years (Adult)

Accepts Healthy Volunteers

Yes

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

Time Frame: 1 year
1 year

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
Menstruation Pattern(Improvement or No Significant Change) of All Participants
Time Frame: 1 year
A method similar to visual analogue scale(VAS) was employed for the evaluation of post-operative menstruation with 0 as amenorrhea and 100 as normal menstruation.

Time Frame: one year
The severity and extent of intrauterine adhesions were scored according to a classification system recommended by the American Fertility Society (AFS) (1988 version) [7]. A score of 1-4 was considered to represent mild adhesions, a score of 5-8 was considered to represent moderate adhesions and a score of 9-12 represented severe adhesions.
