BACKGROUND AND AIM: The purpose of this study was to determine (1) the diagnostic yield for endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in patients with pancreatic cystic lesions, (2) additional value of EUS-FNA over EUS alone in the diagnosis of pancreatic cysts, and (3) diagnostic sensitivity and specificity of EUS and EUS-FNA in the subset of patients where histopathology of surgical specimens were available. METHODS: All patients who underwent EUS examination for the evaluation of pancreatic cystic lesions in six Asian centres were included in the study. RESULTS: Of 298 patients with pancreatic cysts who underwent EUS, 132 (44.3 %) underwent FNA. In the entire cohort, pseudocysts and intraductal papillary mucinous neoplasm (IPMN) were the predominant cystic lesions. The cytologic yield of EUS-FNA was 47 %. On univariate analysis, factors associated with higher cytologic yield included vascular involvement on EUS, presence of solid cystic component, and increased number of needle passes during EUS-FNA. On multivariate analysis, presence of solid cystic components and increased number of needle passes during EUS-FNA were associated with higher diagnostic yield of EUS-FNA. For pancreatic cysts with a solid component, the diagnostic yield of EUS-FNA increased significantly from 44 % with one pass to 78 % with more than one pass (p = 0.016). In the absence of a solid component, the diagnostic yield was 29 % with one pass and was not significantly different from the diagnostic yield of 50 % with more than one pass, p = 0.081. CONCLUSION: The cytologic yield of EUS-FNA was 47 %. When a solid component was present in the cyst, doing more than one pass during EUS-FNA increased its diagnostic yield.
背景与目的:本研究旨在确定(1)内镜超声引导下细针抽吸术(EUS-FNA)在胰腺囊性病变患者中的诊断率,(2)EUS-FNA 相对于单独 EUS 在胰腺囊肿诊断中的额外价值,以及(3)在有手术标本组织病理学的患者亚组中,EUS 和 EUS-FNA 的诊断敏感性和特异性。 方法:所有在六个亚洲中心接受 EUS 检查评估胰腺囊性病变的患者均纳入本研究。 结果:在 298 例接受 EUS 检查的胰腺囊性病变患者中,有 132 例(44.3%)进行了 FNA。在整个队列中,假性囊肿和胰腺导管内乳头状黏液性肿瘤(IPMN)是主要的囊性病变。EUS-FNA 的细胞学检出率为 47%。单因素分析显示,与较高的细胞学检出率相关的因素包括 EUS 上的血管受累、存在实性囊性成分以及 EUS-FNA 期间增加的针数。多因素分析显示,EUS-FNA 中存在实性囊性成分和增加的针数与 EUS-FNA 更高的诊断率相关。对于具有实性成分的胰腺囊肿,EUS-FNA 的诊断率从一次穿刺的 44%显著增加到多次穿刺的 78%(p=0.016)。在没有实性成分的情况下,一次穿刺的诊断率为 29%,与多次穿刺的 50%的诊断率无显著差异(p=0.081)。 结论:EUS-FNA 的细胞学检出率为 47%。当囊肿中存在实性成分时,EUS-FNA 进行多次穿刺可提高其诊断率。
