This study sought to evaluate the performance of cervical digital photography as an alternative to colposcopy.
Colposcopy and cervical digital photography were performed on 228 women. The cervical digital photographs were evaluated through the Internet by three colposcopy experts. The agreement between methods was calculated with kappa and percentages of agreement. Next, the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were calculated for colposcopy and cervical digital photography. Histology was used as the gold standard (Canadian Task Force Classification II-2).
Cervical digital photography and colposcopy were in agreement in 89.9% of the cases (κ = 0.588). Cervical digital photography had higher sensitivity (52.5%) and positive predictive value (60%) than colposcopy (35% and 48.28%, respectively). There were no other significant differences between cervical digital photography and colposcopy: specificity was 91.86% and 91.28%, negative predictive value was 89.3% and 85.8%, and diagnostic accuracy was 84.4% and 80.7%, respectively.
Cervical digital photography is a promising alternative method to colposcopy.
本研究旨在评估宫颈数码摄影作为阴道镜检查替代方法的性能。
对228名女性进行了阴道镜检查和宫颈数码摄影。三位阴道镜专家通过互联网对宫颈数码照片进行评估。采用kappa值和一致性百分比计算两种方法之间的一致性。接下来，计算阴道镜检查和宫颈数码摄影的敏感性、特异性、阳性预测值、阴性预测值和诊断准确性。组织学被用作金标准（加拿大工作组分类II-2）。
宫颈数码摄影和阴道镜检查在89.9%的病例中结果一致（κ = 0.588）。宫颈数码摄影的敏感性（52.5%）和阳性预测值（60%）高于阴道镜检查（分别为35%和48.28%）。宫颈数码摄影和阴道镜检查之间没有其他显著差异：特异性分别为91.86%和91.28%，阴性预测值分别为89.3%和85.8%，诊断准确性分别为84.4%和80.7%。
宫颈数码摄影是一种有前景的阴道镜检查替代方法。
