Comparison of 22G reverse‐beveled versus standard needle for endoscopic ultrasound‐guided sampling of solid pancreatic lesions

Abstract

Although the accuracy of both needle types for proving malignancy was similar, a lower number of passes was required with the FNB needles to achieve the same contributive sample rate as with the FNA needles. FNB also improved the histopathological quality of specimens, suggesting an overall superiority of FNB sampling.
