Accuracy of endoscopic ultrasound‐guided fine needle aspiration cytology on the differentiation of malignant and benign pancreatic cystic lesions: A single‐center experience

Abstract

Although the rate of insufficient cyst fluid aspiration is high, the combination of cytological evaluation and CEA analysis of cyst fluid obtained by EUS-FNA is accurate in differentiating malignant cystic lesions from benign ones. Safe techniques are essential to improve the yield of cyst fluid aspiration by EUS.
