Abstract: Currently, the surgical treatment for cesarean scar defect（CSD）is still unsatisfactory.In the department of Gynecology，the First Affiliated Hospital of Zhengzhou University，based on the pathological changes of CSD：diverticulum formation caused by myometrial discontinuity or defect and the secondary changes of the lining inner surface of diverticulum in the form of inflammatory reaction，congestion, atypical vessel formation and polyp，the laparoscopy-combined hysteroscopy surgical approach was adopted to correct not only the anatomical changes but also the secondary changes. In the surgery the diverticulum wasn't cut open；therefore，the abnormal uterine bleeding symptom can be effectively relieved.Our operative strategy has the advantages of less trauma and faster recovery. In addition，it is more suitable for patients who desire to become pregnant soon after surgery.It's recommended that this approach be used to treat CSD as a new standard surgery.
