目的 探讨阴道镜Reid评分（RCI）的可行性和实用性。方法 以Reid评分为标准,对其进行改良。用5％醋酸涂宫颈后通过阴道镜观察宫颈上皮和血管变化,根据颜色改变、病变边界及血管变化分别评0～2分,取消碘试验,最后以三者之和作出阴道镜诊断,总分0分为正常或慢性宫颈炎、1～2分为CIN、3～4分为CINⅡ、5～6分CINⅢ。结果 阴道镜诊断与组织病理学结果进行对照,完全符合率是60.98％,包括相差一个级别在内者符合率96.95％。阳性率84.75％,假阳性率42.85％,假阴性率16.95％。结论 改良的阴道镜Reid评分（RCI）与组织病理学有较高的符合率,诊断低度病变存在假阳性。
Objective To explore the feasibility and practicability of colposcopy Reid score (RCI). Methods Reid score as a standard, to be improved. Cervical epidermis and blood vessels were observed by colposcopy with 5% acetic acid. According to the change of color, the boundary of the lesion and the changes of blood vessels were respectively evaluated as 0 ~ 2, and the iodine test was canceled. Finally, colposcopy was done with the sum of the three, 0 is divided into normal or chronic cervicitis, 1 to 2 divided into CIN, 3 to 4 divided into CIN Ⅱ, 5 to 6 minutes CIN Ⅲ. Results colposcopy diagnosis and histopathological results were compared, the full compliance rate was 60.98%, including a difference of one level, including the rate of 96.95%. The positive rate was 84.75%, the false positive rate was 42.85% and the false negative rate was 16.95%. Conclusion The modified colposcopy Reid score (RCI) has a high coincidence rate with histopathology, and there is a false positive in the diagnosis of low grade lesions.
