概括

内镜超声波引导细针活检 (EUS-FNB) 可以成为诊断胰腺质量的挑战. 定义不良的边缘或小瘤 (<20毫米) 会降低准确性,但对比剂和经验丰富的内声学家可以改善结果.

科学领域:

胃肠病学胃肠病学
在瘤学瘤学.
诊断成像诊断成像诊断成像

背景情况:

内镜超声波引导细针活检 (EUS-FNB) 是诊断胰腺质量的主要工具.
在接受EUS-FNB的患者中,诊断挑战发生在5-20%的患者中.
识别阻碍诊断和有效救援策略的因素至关重要.

研究的目的:

调查影响胰腺瘤EUS-FNB诊断性能的具有挑战性的特征.
确定潜在的救援方法,以提高困难病例的诊断率.

主要方法:

对经过EUS-FNB (2019年1月至2021年12月) 实质性胰腺瘤患者的回顾性分析.
排除缺乏CT扫描或最终诊断的患者.
多变量分析以确定具有挑战性的特征和有效的救援方法.

主要成果:

在332名患者中,86.1%的患者得到了准确的诊断.
较低的精度与CT上的异衰减,不明确的EUS边缘和瘤大小<20mm有关.
不确定的EUS边缘和瘤大小<20mm是不确定的结果的独立预测因素.
使用对比剂和经验丰富的内声学家 (>5例/月) 改善了诊断性能.

结论:

在EUS或大小小于20mm的边缘不清楚的胰腺瘤对EUS-FNB提出了诊断挑战.
使用对比剂和雇佣经验丰富的内声学家可以显著提高在具有挑战性的EUS-FNB病例的诊断准确性.

Ultrasound II: Endoscopic Ultrasound and FibroScan

Endoscopic Ultrasound (EUS) and FibroScan are valuable diagnostic tools in gastroenterology and hepatology, each with specific applications and techniques.
Endoscopic Ultrasound (EUS):

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
