经会阴与经腹部超声检查对宫颈机能不全诊断的对比研究

Comparative study of Perineal and abdominal ultrasonography in the diagnosis of cervical incompetence

目的：探讨经会阴与经腹部超声检查对宫颈机能不全的诊断的临床价值.方法：将134例孕19～28周采用随机双盲方式进行经会阴与经腹部超声检查,观察两种检查方式的图像满意情况及检查结果的符合情况.结果：经腹部及经会阴超声图像宫颈内口满意度分别为64.2％、97.0％,两者对比x2=44.418,P＜0.01;经腹部及经会阴超声图像宫颈外口满意度分别为53.7％ 、95.5％,两者对比x2=59.610,P＜0.01;而经会阴超声共检出宫颈机能不全33例,检出率为24.6％,经腹部超声检出宫颈机能不全19例,占14.2％,两者对比x2 =4.032,P=0.045.结论：经会阴超声检查诊断宫颈机能不全准确率高,临床操作简单、方便,可更好的早期发现宫颈机能不全,进而实现有效治疗.

Objective To investigate the clinical value of perineal and abdominal ultrasonography in the diagnosis of cervical incompetence. Method 134 cases of 19 -28 weeks gestation were randomly double -blind for perineal and abdominal uhrasonography, Image satis- faction and results of Image compliance in two kinds of inspection were observed. Results The Image satisfaction in abdominal and perineal ~ ~ 2 ultrasonography were 64. 2% ,97. 0%, respectively,compared to two image satisfaction, X = 44. 418 ,P 〈 0. 01. abdominal and perineal ul- trasound images of the cervix, mouth satisfaction were 53.7%, 95.5 %, respectively, compared to two image ＂ ＂ 2 satmfaetlon,2, = 59. 610, P 〈 0. 01. perineal ultrasound cervical incompetence were 33 cases ,the detection rate was 24. 6%, and cervical incompetence diagnosed by ab- dominal ultrasound were 19 eases , the rate was detection 14. 2%, compared to two detection late ,X2 = 4. 032, P = 0. 045. Conclusion The accuracy of Perineal ultrasound in diagnosis of cervical incompetence has a high accuracy rate, Clinical operation is simple and convenient, and it can detection of cervical incompetence early, Thus achieving effective treatment.
