“…Based on the study design, 6 studies were prospective [ 11 , 13 , 18 , 24 , 26 , 27 ], and the remaining 13 were retrospective [ 10 , 12 , 14 - 17 , 19 - 23 , 25 , 28 ]. The diagnostic test was EUS-FNA/FNB in 15 studies [ 10 - 21 , 24 , 25 , 28 ] and EUS-B-FNA [ 22 , 23 , 26 , 27 ] in 4 studies. Ten studies used only a 22-G needle [ 10 - 12 , 14 , 16 , 21 , 22 , 24 - 26 ], 7 studies used a variety of needle sizes ranging from 19-25-G [ 15 , 17 , 18 , 20 , 23 , 27 , 28 ], and 2 studies did not report the type of needle used [ 13 , 19 ].…”
