Comparison of conventional and liquid-based cytology for vaginal stump cytology in SurePathTM preparations in our hospital

Objective : The purpose of this study was to compare the performance of “BD SurePathTM” liquid-based cytology to that of conventional Papanicolaou smears in the junctional zone and vaginal stump. Study Design : The subjects were 433 patients who underwent screening (junctional zone, 318 ; vaginal stump, 115) in our hospital. A split-sample technique was used to create specimens. The cytological diagnosis and specimen adequacy were classified using the 2001 Bethesda System for cervical cytological diagnosis. Judgment as to whether the specimens were satisfactory or unsatisfactory, influence of the background, and diagnosis were compared between the LBC and conventional methods. Results : The unsatisfactory rates were significantly reduced in both the junctional zone and vaginal stump. In the BD SurePathTM method, red blood cells and neutrophil significantly decreased and the rate of judgment of detected LSIL was improved, compared to the conventional method. Conclusions : In vaginal stump cytology, in addition to junctional zone cytology, the BD SurePathTM method proved ideal for preparing satisfactory specimens.
