| Abstract | Since its introduction in clinical practice about two decades ago, EUS-FNA has been one of the most efficient and safe methods to obtain samples from different gastroenterical as well as extraintestinal lesions for cytological and histological analysis [1]. EUS-FNA is of cardinal importance in esophageal, lung, rectal and pancreatic cancer staging [2-4]. Apart from staging, EUS-FNA has also per se indications, representing the procedure of choice for the acquisition of cytological samples from pancreatic and biliary lesions [5,6]. Sensitivity and specificity for the diagnosis of such abnormalities range between 85 and 100% respectively regarding pancreas; sensitivity for biliary strictures varies between 43 and 86% [7,8]. These figures exceed the ones described for alternative approaches such as intraductal ERCP brushing or percutaneous puncture, which entail a higher complication rate [6]. EUS-FNA greatest advantage over the mentioned alternatives regards the real-time needle control provided during the whole operation, thanks to the fact that the device is introduced through the same plane as the ultrasound signal. This allows the endoscopist to puncture aiming towards the spots where the highest quality material presumably will be retrieved and avoid structures that may stand in the way, reducing the risk of secondary complications. In this respect, both EUS elastography and contrast enhanced EUS have been advocated to emphasize the spots within lesions where the chances of obtaining diagnostic specimens are higher. With the latter technique, it has been reported that the hypoenhanced areas within a pancreatic lesion are highly predictive of adenocarcinoma and should be targeted selectively during EUS-FNA [9]. |
