Abstract: Objective：To evaluate the effectiveness and feasibility on treatment of cervical incontinence by cervical cerclage surgery using cerclage tape. Methods：Case 1 owing to cervical incontinence was performed vaginal cerclage during 21w gestation，during 23w gestation she suffered from inevitable abortion and was performed vaginal cerclage again but failed. Finally she was performed abdominal cerclage at non pregnant condition. Case 2 had 5 times mid trimester abortion because of cervical incontinence. She was performed laparoscopic cerclage at non pregnant condition. Both surgeries were going smoothly.Results：Case 1 got pregnant 1 year and 3 months after surgery. At 35+6 w a live girl was born by cesarean section with indication of central placenta previa. Baby’s birth weight was 2 900 g.Case 2 was not pregnant for one year after surgery. HSG shown bilateral tube occluded. Liquid cannulation was performed twice afterwards but tube was still blocked. Conclusions：As for an alternative method, abdominal/laparoscopic cerclage at non pregnant condition is effective to treat cervical incontinence women who had history of mid-trimester abortion even failed of vaginal cerclage.
