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.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| No Intervention: Control group Control group( Intrauterine patients) do not apply intrauterine lavage therapy or intrauterine gel-injection therapy after surgery. |
|
| Experimental: Intrauterine lavage therapy group Intrauterine lavage therapy group apply intrauterine lavage therapy after surgery. |
Drug: Intrauterine lavage therapy
Intrauterine lavage treatment was performed within 3 to 7 days after the first menstrual period after surgery.
|
| Experimental: Intrauterine gel-injection therapy group Intrauterine gel-injection therapy group apply intrauterine gel-injection therapy after surgery. |
Drug: Intrauterine gel-injection therapy
Intrauterine gel-injection treatment was performed within 3 to 7 days after the first menstrual period after surgery.
|
| No Intervention: Healthy control group Healthy control group 1)have regular menstrual cycles,diagnostic hysteroscopy with endometrial biopsy and laparoscopy as part of their infertility diagnostic work-up prior to IVF, hysteroscopy and subsequent pathological results having shown no abnormality in the uterine cavities and abdominal cavity.2) had male partners who were infertile and diagnosed with defective sperm function,such as asthenozoospermia, oligoasthenozoospermia, severe oligoasthenozoospermia and azoospermia, defined according to guidelines published by the World Health Organization. |
Outcome Measures
Primary Outcome Measures
- Endometrial Thickness of All Participants in the Mid Menstrual Measured by Color Doppler Ultrasound [1 year]
Secondary Outcome Measures
- Menstruation Pattern(Improvement or No Significant Change) of All Participants [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.
- Reduction of American Fertility Society adhesion score at Second-look [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.
- Number of Participants With Pregnancy after operation [two years]
- Differences in distribution of reproductive tract bacteria between patients are before and after operation [one year]
- Differences in distribution of reproductive tract bacteria between healthy control group and intrauterine adhesion patients [one year]
