Background: The difference in the diagnostic accuracy of 22- versus 25-gauge needles in EUS-FNA is not clear. Aims: To compare the rates of technical success, diagnostic accuracy and complications of EUS-FNA performed with 22-gauge and 25-gauge needles on the same solid pancreatic mass. Methods: All patients with solid pancreatic masses evaluated from September 2007 to December 2008 were enrolled and underwent EUS-FNA with both 22- and 25-gauge needles with randomisation of needle sequence. The accuracy of the EUS-FNA was determined by comparing the cytological results with the final surgical pathological diagnoses or with the results of a clinical follow-up. A cytological score with different qualitative parameters was created, and a comparison between these parameters was carried out for each needle. Results: Fifty patients with 50 pancreatic masses were recruited. Technical success was 100% and no complications occurred. Diagnostic accuracy was 94% and 86% for the 25- and 22-gauge needles, respectively. Analysis of the cytological score showed a tendency towards the 25-gauge needle, although the difference was not statistically significant. Conclusions: EUS-FNA performed with 22- or 25-gauge needles had the same diagnostic accuracy. Our study results confirm a significant trend towards a better cytological diagnosis for the 25-gauge needle. (C) 2011 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.
