“…Several studies have evaluated the accuracy of cytology after EUS-guided FNA for the diagnostic assessment of pancreatic masses. According to those reports, an adequate cytological specimen can be obtained in 82% to 91% of cases, with a sensitivity for malignancy ranging from 64% to 96% [13][14][15][16][17][18][19][20][21][22][23][24][25] . In our series, the sensitivity of cytology for the diagnosis of malignancy was 68.4%, which improved up to 76.5% when only adequate samples were considered, similar to the previous report.…”

“…In previous studies showing high diagnostic yields of cytology, 3 to 6 needle passes through the lesion [16][17][18][19][20][21][22][23]26] and on-site evaluation of the FNA sample adequacy by a cytopathologist [10,[27][28][29] was considered essential. We were able to obtain an adequate sample in 90% of cases by performing three passes, two for cytological evaluation and one for histological evaluation.…”

“…In this context, the accuracy of EUS-guided FNA is quite high, demonstrating a sensitivity of 80-85% and a specificity near 100% (10,34). However, this technique is technically demanding, often necessitating multiple passes to obtain tissue sufficient for a diagnosis (3,11).…”

“…New techniques also have emerged to address this issue, namely contrast-enhanced EUS (CE-EUS) and EUS elastography (3,31). CE-EUS is a novel approach where the usual high-resolution of ultrasound is intensified by contrast agents (8).…”
