چکیده
Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is a standard procedure for precise histological diagnosis of pancreas tumors, but it is sometimes difficult to obtain adequate specimens. EUS Sonopsy CY® is a newly designed needle with original features. This randomized study will compare the tissue collection rate of EUS Sonopsy CY® to that of a conventional needle in EUS-FNA. The major eligibility criteria are as follows: Patients with a pancreatic mass referred for EUSFNA; age 20 years, and performance status＜4. The primary outcome is the tissue collection rate. This study will elucidate the efficacy of EUS Sonopsy CY®.

متن کاملRandomized Trial Comparing the Flexible 19G and 25G Needles for Endoscopic Ultrasound-Guided Fine Needle Aspiration of Solid Pancreatic Mass Lesions
OBJECTIVES Although a large gauge needle can procure more tissue at endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), its advantage over smaller needles is unclear. This study compared flexible 19G and 25G needles for EUS-FNA of solid pancreatic masses. METHODS This was a randomized trial of patients undergoing EUS-FNA of pancreatic masses using flexible 19G or 25G needle. Main o...

AIM To compare the aspiration needle (AN) and core biopsy needle (PC) in endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of abdominal masses. METHODS Consecutive patients referred for EUS-FNA were included in this prospective single-center trial. Each patient underwent a puncture of the lesion with both standard 22-gauge (G) AN (Echo Tip Ultra; Cook Medical, Bloomington, Indiana...
متن کاملEndoscopic ultrasound-guided sampling of solid pancreatic masses: 22-gauge aspiration versus 25-gauge biopsy needles
BACKGROUND Biopsy needles have recently been developed to obtain both cytological and histological specimens during endoscopic ultrasound (EUS). We conducted this study to compare 22-gauge (G) fine needle aspiration (FNA) needles, which have been the most frequently used, and new 25G fine needle biopsy (FNB) needles for EUS-guided sampling of solid pancreatic masses. METHODS We conducted a re...
