Collection of cervical secretions for local immunological assessment requires that the secretions be collected prior to the Pap smear to avoid contamination with blood. The objective of the present study was to determine whether gentle collection of cervical secretions prior to a Pap smear collection influences the quality of the Pap smear. A total of 266 women were recruited. Half of the participants were assigned to collection of cervical secretions prior to Pap smear collection with Weck-cel sponges. The remaining half had only the Pap smear collection performed. Pap smear slides were reviewed and evaluated for quality by the Bethesda System adequacy criteria without knowledge of randomization. The proportions of limited or inadequate slides in the two study groups were compared by using the Pearson chi-square test. No significant differences were observed between the two study groups when overall Pap smear quality was evaluated (P = 0.29). Comparison of the two study groups with respect to individual adequacy criteria, including presence of air drying artifact, presence of obscuring blood, absence of metaplastic or endocervical cells from the transformation zone, scant cellularity, and presence of obscuring inflammatory cells, also revealed no significant differences between the two study groups. Results from the present study suggest that the collection of cervical secretions with Weck-cel sponges does not adversely impact the quality of subsequently obtained Pap smears.
收集宫颈分泌物用于局部免疫评估要求在巴氏涂片检查之前收集分泌物,以避免被血液污染。本研究的目的是确定在巴氏涂片检查之前轻柔地收集宫颈分泌物是否会影响巴氏涂片的质量。总共招募了266名女性。一半参与者被分配在使用维克塞尔海绵进行巴氏涂片检查之前收集宫颈分泌物。其余一半仅进行巴氏涂片检查。在不知道随机分组情况的前提下,根据贝塞斯达系统的充分性标准对巴氏涂片玻片进行质量审查和评估。使用Pearson卡方检验比较两个研究组中有限或不充分玻片的比例。在评估总体巴氏涂片质量时,两个研究组之间未观察到显著差异(P = 0.29)。在包括存在空气干燥假象、存在遮盖血液、转化区缺乏化生或宫颈内膜细胞、细胞数量稀少以及存在遮盖性炎症细胞等个体充分性标准方面,两个研究组的比较也显示两组之间没有显著差异。本研究结果表明,使用维克塞尔海绵收集宫颈分泌物不会对随后获得的巴氏涂片质量产生不利影响。
