Primary
| Measure | Time frame | Description |
|---|---|---|
| Safety evaluation through vital signs, the results of clinical lab tests and adverse events | 6 months post treatment | Safety evaluation through vital signs, the results of clinical lab tests and adverse events. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change of uterine scar thickness | 6 weeks, 3 and 6 months post treatment | The scar thickness be measured using a transvaginal utrasonography |
| Change of uterine scar area | 6 weeks, 3 and 6 months post treatment | The scar area will be measured using a transvaginal utrasonography |
| Number of participants with endometritis | 6 months post treatment | Endometritis is defined as the presence of at least two of the following signs with no other recognized cause: fever (temperature of at least 38℃), abdominal pain, uterine tenderness, or purulent drainage from the uterus. |
| Number of participants with uterine niche | 6 months post treatment | The niche is defined as a triangular anechoic area at the presumed site of incision in the uterus by transvaginal utrasonography. |
| Immunoglobulin concentrations in breast milk and serum | 6 weeks, 3 and 6 months post treatment | Breast milk and serum immunoglobulin (IgG, IgA, IgM) and the complement (C3, C4) are detected by transmission immune turbidity method using automatic biochemical analyzer. |
| Adverse events occurrence | 6 months post treatment | Adverse events will be evaluated since the baseline visit until 6 months after the end of the treatment. |
| Number of participants with wound infection | 6 months post treatment | Wound infection is defined as the presence of either superficial or deep incisional surgical-site infection characterized by cellulitis or erythema and induration around the incision or purulent discharge from the incision site with or without fever and included necrotizing fasciitis. |
