1019 Prospective Randomized Controlled Trial With Crossover of Endoscopic Ultrasound Fine Needle Aspiration (EUS-FNA) Using 22G Procore and 22G EchoTip Needle for Solid Pancreatic Mass: the “Picore” Study

Prospective Evaluation of New 22 Gauge Endoscopic Ultrasound Core Needle Using Capillary Sampling With Stylet Slow-Pull Technique for Intra-Abdominal Solid Masses

“…12 Recently, 2 prospective randomized clinical trials that compared the 22 G FNB needle with the FNA needle suggested conflicting results, and 1 reason is assumed that there is no standard method in EUS-FNB. 15,16 From our experience, the capillary sampling with stylet slow-pull technique may be considered a reliable method in EUS-FNB, as it showed high histologic adequacy in various intra-abdominal solid masses including pancreatic solid masses and nonpancreatic lesions such as lymphadenopathy or stromal tumor. A multicenter study comparing various EUS-FNB needles using capillary sampling with stylet slow-pull technique is suggested.…”

Basic technique in endoscopic ultrasound-guided fine needle aspiration for solid lesions: What needle is the best?

“…The study concluded that overall histological quality of samples obtained with the 22-G ET (echotip) is better compared with the 22-G P (procore). [ 27 ]…”

“…Core needles are more expensive than aspiration needles. In a larger, prospective, randomized, multicenter trial in France, the 22-gauge ProCore needle was compared with an aspiration needle, the 22-gauge EchoTip (Cook Medical) in 80 patients with a pancreatic mass [12]. EUS-FNA was inconclusive in 7 patients with the EchoTip needle and in 13 patients with the ProCore needle.…”
