Pancreatic cysts are increasingly detected on imaging studies. Accurate determination of the cyst type is important to provide appropriate care for the patients. It is also very clear that not one single modality can provide adequate diagnostic information. A multidisciplinary approach is the key to the diagnosis of pancreatic cysts. In this setting, the role of ancillary testing, which includes biochemical testing (carcinoembryonic antigen and amylase levels in the cyst), molecular testing (e.g., KRAS, GNAS, VHL, and CTNB1), and/or immunohistochemical tests are very important to obtain an accurate diagnosis. This review will discuss helpful ancillary tests in common pancreatic cyst neoplasms and how to approach the diagnosis of pancreatic cysts.

辅助检查对囊性胰腺肿瘤内镜引导下的细针抽吸样品的作用。

在影像学研究中越来越多地检测到胰腺囊肿。准确确定囊肿类型对于为患者提供适当的护理很重要。同样非常清楚的是，没有一种方法可以提供足够的诊断信息。多学科方法是诊断胰腺囊肿的关键。在这种情况下，辅助测试的作用（包括生化测试（囊肿中的癌胚抗原和淀粉酶水平），分子测试（例如，KRAS，GNAS，VHL和CTNB1）和/或免疫组化测试）的作用非常重要准确的诊断。这篇综述将讨论常见的胰腺囊肿肿瘤的辅助检查以及如何诊断胰腺囊肿。
