Core Tip

Core tip: Pancreatic cysts comprise non-neoplastic cysts and neoplastic cysts. It is absolutely essential that an accurate diagnosis is rendered so that effective care can be given to each patient. In many centers, endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) has emerged as the modality of choice that enables one to distinguish between mucinous and non-mucinous lesion, diagnose malignancy and collect cyst fluid for further diagnostic studies, such as pancreatic enzyme levels, molecular analysis, and other tumor biomarkers. The current review will focus on EUS-guided FNA and the cytological diagnosis and new classification for pancreatic cysts.
