阴道镜对不同类型宫颈转化区CIN患者诊断的影响

Colposcope diagnosis in patients with different types of cervical transformation zone CIN

目的 探究不同宫颈转化区型别宫颈上皮内瘤变（CIN）患者阴道镜诊断结果的影响.方法 选取2010年1月～2014年12月在我院进行宫颈电环锥切术（LEEP）的900例患者.对患者进行阴道镜指引宫颈活检,比较不同宫颈转化区的诊断结果.结果 阴道镜诊断为低病变或者正常时,宫颈转化区为Ⅰ、Ⅱ、Ⅲ型患者阴道镜指引宫颈活检与LEEP手术后病理结果的符合率为66.67％、50.00％、50.24％;高病变时为76.65％、70.49％、60.82％.经比较,差异均具有统计学意义（P＜0.05）.经过统计最终诊断为宫颈高级病变的患者为794例,对应于不同的转化类型,阳性率分别为35.35％、41.38％、51.52％.结论 不同宫颈转化区型别对CIN患者阴道镜诊断结果具有不同的影响.从宫颈转化区为Ⅰ型到Ⅲ型,检查后的符合率逐渐降低.

Objective To explore impact of cervical type transformation zone on the results of colposcopy in the di- agnosis of CIN patients. Methods 900 patients were selected from January 2010 to December 2014 in our hospital LEEP surgery. Colposcope guidance cervical biopsy was performed at comparing different cervical transformation of diagnosis. Results When diagnosis as normal or light pathological change with colposcope, the coincidence rates of type Ⅰ , Ⅱ and Ⅲ transformation of the cervical area cervical biopsy guided by colposcope and pathology after LEEP operation were 66. 67%, 66. 67% and 50. 00%. When diagnosis as heavy pathological change with colposcope they were 76.65%, 70.49% and 60.82%. They had significant difference （P〈0.05）. There were 794 cases with heavy pathological change by final diagnosis. The positive rate of type Ⅰ , Ⅱ and Ⅲ transformation of the cervical area were 35.35%, 41.38% and 35.35%. Conclusion Different type cervical transformation zone have different effects on colposcope diagnosis of CIN patients. From the transformation of the cervical area for type Ⅰ to type Ⅲ, the coincidence rate gradually reduces.
