目的 研究胰腺肿块在超声引导下经皮细针穿刺吸取细胞学与组织学诊断方法及临床应用价值。方法 采用细针穿刺吸取细胞涂片 ,同时吸取微型组织块进行组织学观察的 83例进行对比研究。结果 细胞学检查总准确性 98 8% ,敏感性和特异性分别为 98 3%和 10 0 % ;组织学活检分别为 95 1%、93 2 %和 10 0 %。均无假阳性。结论 该诊断方法快速 ,经济实用 ,安全和准确性高。两种方法同时使用可起到互补作用 ,胰腺恶性肿瘤检出率会更高。
Objective To study the diagnostic and clinical value of percutaneous fine needle aspiration in pancreatic masses guided by ultrasound under ultrasound and histology. Methods A total of 83 cases of histological observation were performed with fine needle aspiration and smearing of cell smears. Results The accuracy of cytology was 98 8%, with sensitivity and specificity of 98 3% and 100%, respectively. The histological biopsies were 95 1%, 93 2% and 100%, respectively. No false positives. Conclusion This diagnostic method is rapid, economical and practical, with high safety and accuracy. The simultaneous use of the two methods can complement each other and the detection rate of pancreatic malignancy will be higher.
