AIM:To assess the characteristics and quality of endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) in a large panel of endosonographers.METHODS:A survey was conducted during the 13th annual live course of endoscopic ultrasonography (EUS)held in Amsterdam,Netherlands.A 2-page questionnaire was developed for the study.Content validity of the questionnaire was determined based on input by experts in the field and a review of the relevant literature.It contained 30 questions that pertained to demographics and the current practice for EUS-FNA of responders,including sampling technique,sample processing,cytopathological diagnosis and sensitivity of EUS-FNA for the diagnosis of solid mass lesions.One hundred and sixty-one endosonographers who attended the course were asked to answer the survey.This allowed assessing the current practice of EUS-FNA as well as the self-reported sensitivity of EUS-FNA for the diagnosis of solid mass lesions.We also examined which factors were associated with a self-reported sensitivity of EUS-FNA for the diagnosis of solid mass lesions ＞ 80％.RESULTS:Completed surveys were collected from 92 (57.1％) of 161 endosonographers who attended the conference.The endosonographers had been practicing endoscopy and EUS for 12.5 ± 7.8 years and 4.8 ± 4.1 years,respectively; one third of them worked in a hospital with an annual caseload ＞ 100 EUS-FNA.Endoscopy practices were located in 29 countries,including 13 countries in Western Europe that totaled 75.3％ of the responses.Only one third of endosonographers reported a sensitivity for the diagnosis of solid mass lesions ＞ 80％ (interquartile range of sensitivities,25.0％-75.0％).Factors independently associated with a sensitivity ＞ 80％ were (1) ＞ 7 needle passes for pancreatic lesions or rapid on-site cytopathological evaluation (ROSE) (P ＜ 0.0001),(2) a high annual hospital caseload (P =0.024) and (3) routine isolation of microcores from EUS-FNA samples (P =0.042).ROSE was routinely available to 27.9％ of respondents.For lymph nodes and pancreatic masses,a maximum of three needle passes was performed by approximately two thirds of those who did not have ROSE.Microcores were routinely harvested from EUS-FNA samples by approximately one third (37.2％) of survey respondents.CONCLUSION:EUS-FNA sensitivity was considerably lower than reported in the literature.Low EUS-FNA sensitivity was associated with unavailability of ROSE,few needle passes,absence of microcore isolation and low hospital caseload.
