A Prospective Comparison of EUS-Guided FNA Using 25-Gauge and 22-Gauge Needles

Figure 1

EUS-FNA images for pancreatic head cancer using (a) 22-gauge and (b) 25-gauge needles. The tip of the 22-gauge needle was bent within the lesion during the puncture, and no material was obtained. The arrow indicates the bent tip of the 22-gauge needle. The 25-gauge needle tip remained straight during the EUS-FNA procedure (arrow), and pancreatic adenocarcinoma was diagnosed with EUS-FNA using the 25-gauge needle.
