Abstract：
Pancreatic lesions can be solid or cystic and comprise a wide range of benign, premalignant, and malignant entities. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the current primary sampling method for the preoperative diagnosis of pancreatic lesions. Optimal handling of cytology/small tissue specimens is critical to ensure that the often-scant diagnostic material is appropriately utilized for ancillary and/or molecular studies when appropriate. Ultimately, evaluation of EUS-FNA cytology and small biopsy material can provide accurate and timely diagnoses to guide patient management and triage them to surveillance or surgical intervention.
摘要：
胰腺病变可以是实性或囊性的，包括广泛的良性，癌前病变,和恶性实体。超声内镜引导下细针抽吸术(EUS-FNA)是目前胰腺病变术前诊断的主要采样方法。细胞学/小组织标本的最佳处理对于确保经常很少的诊断材料在适当时被适当地用于辅助和/或分子研究至关重要。最终,评估EUS-FNA细胞学和小活检材料可以提供准确和及时的诊断，以指导患者管理和分诊，以进行监测或手术干预。
