Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Estrogen Intrauterine Stent System
An Intrauterine Stent System with estrogen will be introduced into the uterine cavity after TCRA(transcervical resection of adheison).
|
A Estrogen Intrauterine Stent System(E-IUS)will be introduced post-operatively.
The E-IUS will be removed 60 days after surgery with continuous dydrogesterone administration for 5 days at 20 mg/d, and routine management.
|
Other: Foley balloon combined with self-cross-link sodium hyaluronate gel
Subjects will be given Foley balloon (manufacturer: Zhanjiang Star Enterprise Co., Ltd.) combined with self-cross-linked sodium hyaluronate gel (manufacturer: BioRegen Biomedical (Changzhou) Co., Ltd.) after TCRA surgery.
|
Foley balloon combined with self-crosslinking sodium hyaluronate gel will be introduced post-operatively,2 cycles of estrogen-progestin sequential therapy comprised of continuous estrogen and progestin added in the second half of the cycle or continuous estradiol valerate for 60 days, followed by dydrogesterone for 10 days

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Post-operative adhesion recurrence rate(%)
Time Frame: 60 days
|
The severity of adhesion will be assessed by hysteroscopy before and on d60 after surgery using the America Fertility Score (AFS) system.
If the AFS score on D60 second-look hysteroscopy over 0 will be considered as adhesion recurrence.
Post-operative adhesion recurrence rate(%)=(patients whose AFS score >0-point after surgery/All patients after surgery)X100%.
The recurrence rate (%) is range from 0(Mini) to 100(Max).The lower the recurrence means the patient has a better post-operative outcome.
