摘      要：BACKGROUND Reverse bevel(RB)needle is widely used for endoscopic ultrasound fine needle biopsy(EUS-FNB).A 3-plane symmetrical needle with Franseen geometry(FG)has recently become *** To compare the clinical efficacy of FG to that of RB *** A retrospective cohort study of all adult patients who underwent EUS-FNB for solid and mixed lesions either with 22G RB needle or 22G FG needle between January 2016 and February 2019 was *** cytology slides were reviewed by an independent gastrointestinal cytopathologist blinded to the needle used and the initial cytology *** primary and secondary outcomes were to assess the sample adequacy using Euro-cytology criteria and the number of cell clusters,*** Two hundred and twenty six procedures were included in the *** needle was used in 128 procedures and FG needle in 98 *** baseline characteristics of both groups were *** multivariable analysis,FG needle(P=0.02)and location of the lesion(P0.01)were independently associated with adequate ***,the use of FG needle(P=0.04)and the size of the lesion(P=0.02)were independently associated with acquisition of increased number of cell *** FG needle is superior to RB needle in acquiring adequate tissue and attaining higher number of cell clusters for solid and mixed lesions.
