EUS-FNA of Solid Pancreatic Mass: Comparison Between Negative Pressure and Slow-pull Technique (EUS-FNA)

April 11, 2017 updated by: University of Sao Paulo General Hospital

Endoscopic Ultrasound-guided Fine Needle Aspiration (EUS-FNA) of Solid Pancreatic Mass: Comparison Between Negative Pressure and Slow-pull Technique

50 patients with pancreatic mass will undergo endoscopic ultrasound-guided fine needle aspiration using two techniques: negative pressure and slow-pull. Cytological results will be compared.

Detailed Description

The study will analyze the cytological results of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of pancreatic mass using two different techniques of needle suction. Negative pressure and slow-pull. 50 patients with pancreatic mass will be submitted to four passes with both techniques. Each patient will be randomized to decide which technique will be first and subsequently on a alternated fashion until four passes are completed. Smear cytology and cell block preparations for each technique were obtained. The pathologist was blinded for the EUS-FNA technique.
