Feasibility of a 20-gauge ProCore needle in EUS-guided subepithelial tumor sampling: a prospective multicenter study

Table 2 Procedural characteristics and outcomes of the EUS-guided fine-needle biopsies

Diagnosis achieved	32 (88.9)
Sample adequacy during three needle passes
Macroscopic adequacy	35 (97.2)
Definite tissue core	32 (88.9)
Suspicious tissue core	3 (8.3)
Histological adequacy	32 (88.9)
Number of required needle passes to obtain optimal tissue core sample^a
Macroscopic	1.2 ± 0.6
Histological	1.5 ± 1.0
Technical failure	2 (5.6)
Adverse events	2 (5.6)

Variables are presented as number (%) or mean ± standard deviation
^aIf the optimal core sample was not obtained after three needle passes, the number of passes required was considered to be four
