[Endoscopic ultrasound in the diagnosis of pancreatic cystic lesions].

Pancreatic cystic lesions are increasingly being detected in clinical practice. They are commonly asymptomatic and incidentally discovered. Distinction between neoplastic and benign lesions is crucial for determining treatment but definite diagnosis is often difficult. Endoscopic ultrasound (EUS), with additional EUS-guided fine needle aspiration (EUS-FNA), has emerged as an ideal technique in the evaluation of these lesions.
