Comparison of cytobrush with Cervex-Brush for endocervical cytologic sampling.

This study was designed to compare the quality of the Papanicolaou (Pap) smear and side effects associated with the Ayres spatula/cytobrush combination and the Cervex-Brush. We evaluated 165 Pap smears, of which 84 (51%) were cytobrush/spatula specimens, and 81 (49%) were from Cervex-Brush specimens. The cytobrush/Ayres spatula combination and the Cervex-Brush alone were equally successful in detecting squamous cells, however, the cytobrush/Ayres spatula combination was significantly better in picking up endocervical cells than the Cervex-Brush (p less than 0.01). There were no significant differences between the two techniques in degree of bleeding and pain in adolescents. The combination of the cytobrush and spatula appears to be superior to the Cervex-Brush alone in producing adequate Pap smears.
