随着荧光成像技术的不断进步，ICG作为一种近红外荧光染料，在肝胆胰外科领域展现出广泛应用前景。本文对ICG在该领域的应用进行了全面梳理和深度探讨。ICG凭借其独特的荧光特性，在肝功能评估方面，实现了对肝脏摄取和排泄功能的实时动态监测，为临床医生提供了更准确的肝脏功能状态信息；在肝脏肿瘤诊断与治疗中，ICG荧光成像技术以其高灵敏度和特异性，清晰地显示肿瘤边界和微小病灶，有力地支持了精准手术切除；在胆道应用方面，ICG使胆道造影更加清晰，有效降低了胆道损伤风险，并在胆瘘监测中发挥独特优势，助力及时发现和处理术后并发症；在胰腺应用方面，ICG为胰腺肿瘤的诊断和手术导航开辟了新的途径。然而，ICG在应用中也存在特异性有限、荧光信号易受干扰、成本较高等问题。

With the continuous advancement of fluorescence imaging technology, Indocyanine Green (ICG), as a near-infrared fluorescent dye, has demonstrated broad application prospects in the field of hepatobiliary and pancreatic surgery. This article conducts a comprehensive collation and in-depth exploration of the applications of ICG in this field. Leveraging its unique fluorescent properties, ICG achieves real-time dynamic monitoring of liver uptake and excretion functions in terms of liver function assessment, providing clinicians with more accurate information on the functional status of the liver. In the diagnosis and treatment of liver tumors, ICG fluorescence imaging technology, with its high sensitivity and specificity, clearly displays tumor boundaries and tiny lesions, strongly supporting precise surgical resection. In biliary applications, ICG enhances the clarity of cholangiography, effectively reducing the risk of biliary tract injury, and plays a unique role in bile leakage monitoring, facilitating the timely detection and management of postoperative complications. In pancreatic applications, ICG has opened up new avenues for the diagnosis of pancreatic tumors and surgical navigation.
