Abstract

Background/aims: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) using Franseen needles is reportedly useful for its high diagnostic yield. This study compared the diagnostic yield and puncturing ability of EUS-TA using 22-gauge cobalt-chromium (CO-Cr) needles with those of stainless-steel Franseen needles in patients with solid pancreatic lesions.

Methods: Outcomes were compared between the 22-gauge Co-Cr Franseen needle (December 2019 to November 2020; group C) and stainless-steel needle (November 2020 to May 2022; group S).

Results: A total of 155 patients (group C, 75; group S, 80) were eligible. The diagnostic accuracy was 92.0% in group C and 96.3% in group S with no significant intergroup differences (p=0.32). The rate of change in the operator (from training fellows to experts) was 20.0% (15/75) in group C and 7.5% (6/80) in group S. Stainless-steel Franseen needles showed less inter-operator difference than Co-Cr needles (p=0.03).

Conclusion: Both Co-Cr and stainless-steel Franseen needles showed high diagnostic ability. Stainless-steel Franseen needles are soft and flexible; therefore, the range of puncture angles can be widely adjusted, making them suitable for training fellows to complete the procedure.

22 号钴铬合金针与不锈钢弗兰森针在内窥镜超声引导下对胰腺实变患者进行组织采集的对比。

背景/目的：据报道，使用弗朗森针进行内镜超声引导下组织采集（EUS-TA）具有很高的诊断率。本研究比较了在胰腺实变患者中使用 22 号钴铬合金针和不锈钢弗朗森针进行 EUS-TA 的诊断率和穿刺能力：比较22号钴铬合金弗兰森针（2019年12月至2020年11月；C组）和不锈钢针（2020年11月至2022年5月；S组）的结果：共有 155 名患者符合条件（C 组 75 人；S 组 80 人）。C 组的诊断准确率为 92.0%，S 组为 96.3%，组间差异不显著（P=0.32）。C组操作者（从培训研究员到专家）的变化率为20.0%（15/75），S组为7.5%（6/80），不锈钢弗兰森针的操作者间差异小于铬镍合金针（P=0.03）：结论：钴铬针和不锈钢弗兰森针均显示出较高的诊断能力。不锈钢弗朗森针柔软而灵活，因此穿刺角度的调整范围大，适合培训研究员完成手术。
