Endoscopic ultrasound-guided fine-needle aspiration cytology in the diagnosis of intraductal papillary mucinous neoplasms of the pancreas. A study of 8 cases.

Context: Intraductal papillary mucinous neoplasm (IPMN) is an increasingly recognized neoplasm of the pancreas, accounting for 5% of pancreatic neoplasms, it is considered difficult to diagnose by fine-needle aspiration (FNA) cytology.

Objective: The aim of this study was to investigate the role of EUS-guided FNA cytology in the diagnosis of IPMN of the pancreas.

Patients: Eight cases of surgically proven IPMN with pre-operative endoscopic ultrasound-guided (EUS-guided) FNA cytology were collected for retrospective analysis.
