The aim of this study was to evaluate the touch preparation (imprint) cytology method for obtaining rapid interpretations from core material obtained during abdominal percutaneous biopsy.
For 28 patients undergoing biopsy of abdominal masses, paired slides were prepared for rapid staining by use of smears of standard fine-needle aspirates and by use of a touch preparation of the core material obtained with a semiautomated biopsy gun. The slides were scored in comparison with the final cytopathologic and histopathologic diagnosis.
Touch preparation slides were equivalent in diagnostic yield to fine-needle aspirate smears, demonstrating similar cellular features. Touch preparation slides revealed features of tumor architecture not present on smears.
Touch preparation cytology offers rapid diagnosis from a single core biopsy sample. Carefully performed, the touch preparation method preserves the core material for subsequent permanent fixation and sectioning.
本研究旨在评估触摸制备（印片）细胞学方法，以从腹部经皮活检获取的核心材料中获得快速诊断结果。
对28例接受腹部肿块活检的患者，通过标准细针穿刺抽吸涂片以及使用半自动活检枪获取的核心材料进行触摸制备，制备配对玻片用于快速染色。将玻片与最终的细胞病理学和组织病理学诊断结果进行评分比较。
触摸制备玻片的诊断率与细针穿刺抽吸涂片相当，显示出相似的细胞特征。触摸制备玻片揭示了涂片上不存在的肿瘤结构特征。
触摸制备细胞学可从单个核心活检样本中实现快速诊断。操作仔细的话，触摸制备方法可保留核心材料用于后续的永久固定和切片。
