A Comparative study of visual inspection with acetic acid versus PAP smear in detection of cervical dysplastic lesions in ante – natal women

Abstract

Aim Of The Study: To Compare the method of visual inspection with acetic acid(VIA) with pap smear in detection of cervical dysplastic lesions in antenatal women. Materials And Method: It was a prospective study performed in 113 antenatal patients between 16-28 weeks of gestation.The pap smear and VIA performed for all patients in the study group. Positive screens were classified as atypical squamous cells of undetermined significance; low-grade or high-grade squamous intraepithelial lesion, including those showing atypia, cervical intraepithelial neoplasia, or carcinoma-in-situ. All patients with positive pap screens or positive for aceto white lesions were subjected to colposcopy. Results: Out of the 113 patients screened 10 patients were VIA positive,among them 3 were found to be colposcopically positive. one patient found to be pap smear positive, and subsequently found to be positive. In our study the detection rate of VIA was 2.65%, and pap smear was 0.88%. In our study the ratio of detection rate between VIA/PAP smear 3.01.Specificity for VIA in our study is 93.6% and for pap smear sensitivity is 100%. Conclusion: We conclude that VIA is more specific than PAP smear in detection of cervical dysplastic lesions among antenatal women.
