Summary

Background: EUS-guided fine needle aspiration (EUSFNA) is a well established technique for tissue acquisition and diagnosis with excellent safety profile. The overall diagnostic yield of EUSFNA exceeds 80%, with higher rates in EUSFNA of lymph nodes, where rates of \>90% may be expected, as compared to pancreatic masses, where lower diagnostic rates were reported. To maximize the diagnostic yield, at least 3 needle passes are required for lymph nodes and at least 4 passes for pancreatic masses. Olympus has recently made commercially available a new 22 gauge FNA needle (EZ Shot 2 with side port) with a side port at the needle tip. The theoretical basis for introduction of the side port is to increase the diagnostic yield. Preliminary unpublished retrospective data suggested the yield might be raised. However, there are no prospective multicenter randomized controlled studies to ascertain the validity of the assumption.

Aim: To determine whether there is a difference in diagnostic yield between EZ-Shot 2 and EZ-Shot 2 with side port in patients with pancreatic masses for evaluation.

Methods: Patients with pancreatic masses referred for EUSFNA will be recruited prospectively and randomized to either EZ-Shot 2 or EZ Shot 2 with sideport for the first puncture, and then the alternative needle will be used for repeated punctured. The cytological and diagnostic yield at first pass for both needles will be compared.

Clinical significance: This will determine whether the new needle design can further improve the diagnostic yield of EUSFNA of pancreatic masses.
