概括
内胆囊 (IC) 印ocyanine绿色 (ICG) 染料在腹腔镜胆囊切除术期间提供更快的胆道树可视化,与静脉 (IV) 给药相比. 这种方法可以在不等待肝脏分泌的情况下立即使用,提高了外科手术的清晰度.
科学领域:
- 手术创新 在外科创新.
- 医疗成像医学成像
- 胃肠病学 胃肠病学
背景情况:
- 带有近红外光的印ocyanine绿色 (ICG) 染料有助于在腹腔镜胆囊切除术 (LC) 期间可视化肝外胆道解剖.
- 静脉注射 (IV) 是常见的,通常在手术前30-60分钟.
- 在胆囊内 (IC) 直接注射到胆囊中不太常见,但在这里进行了探索.
研究的目的:
- 为了比较IV-ICG与IC-ICG在LC期间可视化肝外胆道解剖学的疗效.
- 评估两种ICG给药途径之间的胆道可视化的速度和质量.
主要方法:
- 40名接受选择性LC的患者随机分为两个组:IV-ICG (n=20) 和IC-ICG (n=20).
- ICG是静脉注射 (0.01 mg/kg,麻醉前30-45分钟) 或直接注射到胆囊底部.
- 比较了可视化得分和胆道树光出现的时间.
主要成果:
- 这两种方法都提供了良好的可视化,平均得分为4.25 (IV-ICG) 和4.1 (IC-ICG).
- 与IV-ICG (70%前,85%后) 相比,内胆囊内注射显示出囊管划界率更高 (85%前剖析,95%后剖析).
- 常见胆管可视化对两者都很好 (95%的IV-ICG,100%的IC-ICG),尽管IV-ICG对常见的肝管更好 (85%vs45%). 在两名IC-ICG患者中发生了轻微的胆汁泄漏.
结论:
- 内胆囊性ICG在LC期间提供了更快的肝外胆道可视化.
- IC-ICG提供了更好的信号与背景比,可以立即使用.
- 这种技术消除了手术前等待肝脏分泌染料的需要.

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

Endoscopic Procedures V: ERCP
2.8K
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.
