Abstract

Background And Objectives: Diagnosis of pancreatic lesions remains a clinical challenge. This study aimed to evaluate the diagnostic accuracy of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in pancreatic mass lesions.

Patients And Methods: Clinical data, laboratory tests, and cytopathological and imaging reports were collected from 185 pancreatic EUS cases performed from March 2010 to January 2014. The final diagnosis was based on surgical findings, EUS-FNA or computed tomography (CT)-guided biopsy.

Results: A total of 100 pancreatic FNAs were obtained by EUS. Most positive diagnoses of malignancy were pancreatic adenocarcinomas (n = 61). The site of pancreatic adenocarcinoma was the head in 50 (82.0%), body in seven (11.5%), and tail in four (6.5%). The sensitivity, specifi city, and positive and negative predictive values of EUS-FNA for diagnosing adenocarcinoma were 80.3%, 92.3%, 94.2%, and 75.0%, respectively.

Discussion: We concluded that EUS-FNA of pancreatic lesion accurately diagnoses pancreatic adenocarcinoma and should be considered for the standard management of pancreatic adenocarcinoma.
