摘要

Endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNA/B) is a standard method for pathological diagnosis of pancreatic solid lesions. The EchoTip ProCore 20G? (PC20), a 20-gauge biopsy needle with a forward-bevel core trap, has been available in Japan since 2015. We compared the efficacy of the PC20 with that of the EchoTip ProCore 22G? (PC22) and Acquire 22G? (AC22) in EUS-FNA/B for diagnosing pancreatic cancer. This retrospective study included 191 patients with pancreatic cancer who underwent EUS-FNA/B using the PC20, PC22, or AC22 at our facility from April 2013 to October 2019. We investigated the patients’ clinical characteristics and the diagnostic accuracy and safety of each needle. A sufficient stroke length of puncture was secured in all patients. The maximum length under EUS was shorter with the AC22 (22.1?±?2.2?mm) than PC20 (30.6?±?0.7?mm, p 0.99). One patient (0.9%) in the PC20 group developed mild pancreatitis, but no adverse events occurred with the other needles. The PC20 showed better diagnostic capability than the PC22. The diagnostic efficacy was similar between the PC20 and AC22. The high histological accuracy of the PC20 could be advantageous for lesions in which histological assessment is critical.

(AC22)在EUS-FNA / B中用于诊断胰腺癌。该回顾性研究包括191例胰腺癌患者,胰腺癌在2013年4月至2019年4月,我们的工厂使用PC20 。在所有患者中确保了足够的刺穿穿刺长度。 EUS下的最大长度与PC20(30.6?±2.2Ω2.2Ω·2.2Ω·2.2Ω·2.2Ω·±0.7Ω·mm,p 0.99)短。 PC20组中的一名患者(0.9%)发育了轻度胰腺炎,但另一个针不会发生不良事件。 PC20显示出比PC22更好的诊断能力。 PC20和AC22之间的诊断效果类似。 PC20的高组织学精度对于病变可能是有利的,其中组织学评估至关重要。
