Not applicable Interventional Xinhua Hospital, Shanghai Jiao Tong University School of Medicine · NCT05205317

This study is testing if adding metformin to vaginal repair can help women with cesarean section scar defects have better healing and less menstrual bleeding compared to just vaginal repair alone.

What this trial studies

This clinical trial evaluates the effectiveness of vaginal repair combined with metformin versus vaginal repair alone in treating cesarean section scar defects (CSD). CSD is linked to abnormal uterine bleeding, and the study aims to improve outcomes for women suffering from prolonged menstrual flow. Participants will be randomized to receive either the combination treatment or the standard vaginal repair. The trial seeks to determine if metformin, known for its anti-aging properties, can enhance the healing process and reduce menstrual duration.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 to 40 diagnosed with CSD and experiencing prolonged menstrual flow.

Not a fit: Patients over 40, those with malignant tumors, or severe medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve menstrual health and quality of life for women with cesarean section scar defects.

How similar studies have performed: While the use of metformin in this context is novel, previous studies have shown its effectiveness in other clinical applications, suggesting potential for success.
