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 available.
AIM
To compare the clinical efficacy of FG to that of RB needle.
METHODS
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 undertaken. All cytology slides were reviewed by an independent gastrointestinal cytopathologist blinded to the needle used and the initial cytology report. The primary and secondary outcomes were to assess the sample adequacy using Euro-cytology criteria and the number of cell clusters, respectively.
RESULTS
Two hundred and twenty six procedures were included in the study. RB needle was used in 128 procedures and FG needle in 98 procedures. The baseline characteristics of both groups were comparable. On multivariable analysis, FG needle ( = 0.02) and location of the lesion ( < 0.01) were independently associated with adequate tissue. Further, the use of FG needle ( = 0.04) and the size of the lesion ( = 0.02) were independently associated with acquisition of increased number of cell clusters.
CONCLUSION
FG needle is superior to RB needle in acquiring adequate tissue and attaining higher number of cell clusters for solid and mixed lesions.
背景
反斜面（RB）针广泛用于内镜超声引导下细针穿刺活检（EUS-FNB）。一种具有 Franseen 几何形状（FG）的三平面对称针最近已上市。
目的
比较 FG 针与 RB 针的临床疗效。
方法
对 2016 年 1 月至 2019 年 2 月期间使用 22G RB 针或 22G FG 针对实性和混合性病变进行 EUS-FNB 的所有成年患者进行回顾性队列研究。所有细胞学玻片均由一位独立的胃肠道细胞病理学家进行审查，该病理学家对所使用的针和初始细胞学报告不知情。主要和次要结局分别是使用欧洲细胞学标准评估样本充足性和细胞簇数量。
结果
本研究纳入了 226 例操作。128 例操作使用了 RB 针，98 例操作使用了 FG 针。两组的基线特征具有可比性。在多变量分析中，FG 针（P = 0.02）和病变位置（P < 0.01）与获得充足组织独立相关。此外，FG 针的使用（P = 0.04）和病变大小（P = 0.02）与获得更多细胞簇独立相关。
结论
对于实性和混合性病变，FG 针在获取充足组织和获得更多细胞簇方面优于 RB 针。
