Prospective comparative study of the EUS guided 25‐gauge FNA needle with the 19‐gauge Trucut needle and 22‐gauge FNA needle in patients with solid pancreatic masses

Abstract

The 25-gauge FNA needle was significantly superior in terms of technical success rate and overall diagnostic accuracy, especially for the head and uncinate lesions, compared to the 22-gauge and Trucut needles and could be considered 'the best choice needle for cytological diagnosis' of solid pancreatic lesions. If histological diagnosis is required, the 22-gauge FNA needle and Trucut needle may be advantageous for use in head/uncinate and body/tail lesions, respectively.
