Endoscopic ultrasound in the evaluation of pancreatic cystic lesions: Initial results

Background: Pancreatic cystic lesions (PCL) are increasingly recognized with the routine use of computed tomography. The differential diagnoses vary widely from benign to malignant. Endoscopic ultrasound (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) play a central role in the diagnosis and management of pancreatic cysts. Aim: To assess the role of EUS in the diagnosis of incidental PCL. Patients and Methods: Consecutive patients with incidental PCL underwent EUS and EUS-FNA. Pancreatic cyst fluid was collected for cytopathological analysis and measurement of amylase, carcinoembryonic antigen (CEA) levels…
