Endoscopic ultrasound-guided tissue acquisition of solid mass lesions of the pancreas: A retrospective comparison study of fine-needle aspiration and fine-needle biopsy.

Our results demonstrate that for solid pancreatic lesions, the diagnostic yields of FNA, FNB, and combined FNA and FNB are comparable. Presence of ROSE and increasing lesion size increased the diagnostic yield while the number of passes had no significant impact.
