目的 探讨胰腺囊性病变行超声内镜下细针穿刺活检术的诊断体会。方法 分析我院30例胰腺囊性病变行传统影像学检查(CT、MRI、B超)、EUSFNA的临床资料,其中16例行液基细胞学(LBC)、细胞块检查。通过比较各种检查结果的诊断正确率、灵敏度、特异度、Youden指数,确定EUSFNA对于胰腺囊性病变的诊断价值,并以此总结胰腺囊性病变行超声内镜下细针穿刺的操作技巧。结果 胰腺癌6例,囊腺癌4例,假性囊肿14例,黏液性囊腺瘤4例,胰腺导管内乳头状黏液瘤(IPMN)2例。传统影像学、EUSFNA、LBC、细胞块的诊断正确率为56.67%、90%、73.33%、100%(P<0.05)。EUSFNA较单纯传统影像学的灵敏度、特异度、Youden指数均高(90%、79.17%、0.69 vs 56.67%、54.17%、0.11)。结论 EUSFNA可提高诊断胰腺囊性病变的准确性,掌握超声内镜下细针穿刺操作技巧尤为重要。
ObjectiveTo investigate the diagnostic value of endoscopic ultrasonographyguided fine needle aspiration (EUSFNA) in the pancreatic cystic lesions. MethodsForm Jan 2010 to Dec 2014, the clinical data of 30 patients with pancreatic cystic disease were retrospectively reviewed including traditional imaging tests(CT、MRI、Bultrasound) and EUSFNA. 16 cases were routinely underwent liquidbased cytology(LBC) and cell blocks by EUSFNA. Through comparation with the accuracy, sensitivity, specificity and Youden index of all kinds of examination, the diagnostic value of EUSFNA was confirmed and the operation skill concluded in pancreatic cystic diseases. Results6 cases were diagnosed as pancreatic cancer, 4 cases cystadenocarcinomas,14 cases pancreatic pseudocyst, 4 cases mucinous cystadenoma and 2 cases intraductal papillary mucinous neoplasm (IPMN). The diagnostic accuracy of traditional imaging tests、EUSFNA、LBC and cell blocks were respectively 56.67%、90%、73.33%、100% (P<0.05). Compared with traditional imaging tests, the sensitivity、specificity、Youden index of EUSFNA were higher(90%、79.17%、0.69 vs 56.67%、54.17%、0.11).The sensitivity of cell blocks was higher than LBC(100% vs 75%). ConclusionEUSFNA can improve the diagnostic accuracy of pancreatic cystic lesions and it is important to master skill of EUSFNA.
