Brief Summary:
This study aimed to investigate the effects of probiotics in combination with pelvic floor muscle electrophysiologic therapy on the uterine endometrial repair and reproductive prognosis in patients after surgery for intrauterine adhesion

Condition or disease Intervention/treatment Phase
Uterine Endometrial Repair Drug: probiotics Device: Electrophysiologic Therapy Not Applicable

Detailed Description:
Post-traumatic repair disorder of endometrium can cause intrauterine adhesions, amenorrhea and infertility, which seriously endanger women's reproductive health. In our previous study, high throughput sequencing of intrauterine microorganisms showed that the content of lactic acid bacteria in the uterine cavity of patients with intrauterine adhesions was significantly lower than that of normal people. Concurrently, our previous studies found that chronic endometritis can aggravate endometrial fibrosis, then affect the repair of endometrial trauma, and increase the recurrence of intrauterine adhesion. Our previous study also suggest that stem cells are beneficial to the repair of endometrium. Studies have shown that lactic acid can inhibit inflammatory response and regulate the proliferation of intestinal stem cells. So can lactic acid also change the microbial environment in uterine cavity to inhibit endometrial inflammation and regulate the proliferation of endometrial stem cells to help repair endometrial wounds? In addition, electrical stimulation can relieve depression and anxiety and play a sedative effect. In recent years, some studies have shown that pelvic floor electrophysiological therapy can improve the intimal blood flow resistance index of thin endometrium. Therefore, whether or not the pelvic floor electrophysiological therapy can repair the endometrium after the intrauterine adhesion. We expect probiotics and electrophysiologic therapy can promote endometrial repair after electrosurgical resection of intrauterine adhesions.

Primary Outcome Measures :
  1. Endometrial Thickness [ Time Frame: Within the first 3 months after surgery ]
    All Participants in the Mid Menstrual Measured by Color Doppler Ultrasound

Secondary Outcome Measures :
  1. Menstruation Pattern of All Participants [ Time Frame: Within the first 3 months after surgery ]
    A method similar to VAS was employed for the evaluation of post-operative menstruation with 0 as amenorrhea and 100 as normal menstruation.

  2. Reduction of American Fertility Society adhesion score at Second-look hysteroscopy of All Participants [ Time Frame: Within the first 3 months after surgery ]
    The severity and extent of intrauterine adhesions were scored according to a classification system recommended by the American Fertility Society (AFS) (1988 version). 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.
