目的 探讨术前细针穿刺细胞块对胰腺占位性病变的诊断价值.方法 回顾分析本院2005年1月至2010年6月收治的胰腺占位性病变83例,术前均行B超引导下穿刺作细胞学涂片及细胞块检查,并与最终病理诊断作对比研究.结果 细胞学涂片和细胞块切片的准确性分别为89.2%、97.6%,两者比较差异显著(P＜0.05).细胞块诊断实性假乳头状瘤和胰腺内分泌肿瘤的准确性均为100%.结论 术前穿刺细胞块检查可提高诊断的准确性.细胞块结合免疫组化分析,有助于提高胰腺肿物的分型,尤其是实性假乳头状瘤和胰腺内分泌肿瘤的检出率,减少漏诊和误诊.“,”Objective To investigate the diagnostic value of fine needle aspiration cell block to the pancreatic lesion. Methods From January 2005 to June 2010 there were 83 patients with pancreatic lesion were selected. Preoperatively they underwent ultrasound guided fine needle aspiration cytology (FNAC) and cell block,and the diagnosis results of them were compared with the final diagnosis available. Results Accuracy of FNAC and cell block were 89. 2% , 97.6% , there was a statistic difference ( P ＜ 0. 05 ). The accuracy of cell block for Solid pseudopapillary tumor of the pancreas (SPTP) and pancreatic endocrine tumor werel00%.Conclusion Ultrasound guided fine needle aspiration of cell block of the pancreas may increase the accuracy of pancreatic lesion. The combination of IHC staining to the cell block may have a high applied value to histological typing in pancreatic lesion, especially for SPTP and pancreatic endocrine tumor.
