Background: Cervical cancer-a preventable disease, is the second most commonly diagnosed cancer among women of developing countries. Paps smear is the gold standard screening method worldwide. But a low-cost test, visual inspection of cervix with acetic acid (VIA) has been emerged as an alternative for use in lowresource settings. VIA is simple and easy to perform by auxiliary health professionals. Colposcopy is an essential procedure in the evaluation of screen positive cervix though it requires considerable training and experience. Objective: The objective of this study was to evaluate the VIA positive cases by colposcopy, colposcopy guided biopsy and histopathological examination.
Methods: This was a cross sectional observational study conducted among 100 VIA positive cases attended at GOPD of Dhaka Medical College Hospital from July 2014 to December 2014. Colposcopy was performed in all VIA positive cases. Subsequent biopsy and histopathological examinations were done for those with colposcopic abnormal findings.
Results: The mean age of the study population was 37.9±9.3 years. Among VIA positive cases 66.0% had complaints of whitish vaginal discharge. Among the study population, colposcopically 46.0% had healthy cervix (normal) and 54.0% had abnormal findings. Colposcopy guided biopsy was taken from those with abnormal findings. Histopathological findings were normal in 38.9% cases, chronic cervicitis in 20.37% cases, squamous cell metaplasia in 3.7% cases, CIN I in 16.7%, CIN II in11.11%, CIN III in 5.6% and 3.7% cases were carcinoma cervix. True positive value was 20, false positive value 34 and positive predictive value of colposcopy was 37.03%.
Conclusion: This study concluded that VIA is effective in detection of CIN and invasive carcinoma of cervix. It also suggests the role of colposcopy in the evaluation of CIN and other cervical diseases in screen positive cases. VIA can be used as a screening tool in low and middle income countries like Bangladesh, not only in rural areas and small health centres, but also in hospitals, cancer institutes, and other health facilities with better resources.
