研究目的:

吲哚菁绿(indocyanine green,ICG)被广泛应用于荧光腹腔镜胆囊切除术(laparoscopic cholecystectomy,LC)中,以实现肝外胆管的清晰显影,为手术医生提供即时的视觉引导。尽管众多研究已证实,在LC手术中采用ICG荧光显影技术能有效减少胆道损伤(bile duct injury,BDI)的风险,但ICG在肝脏内的滞留现象会产生强烈的背景荧光,这无疑增加了从肝脏的荧光背景中准确辨识胆管的难度。因此,如何精确调控ICG在手术前的给药剂量,以确保达到肝外胆道最佳显影效果,仍是当前亟待探索与解决的关键问题。本研究探索在0.5-3小时的时间窗口内,不同剂量的ICG在手术过程中的荧光显影成效,旨在通过对比分析,确定出最佳的显影剂量,为临床实践提供有价值的参考依据。  

Objectives of Study:

Indocyanine green (ICG) is widely used in fluorescence laparoscopic cholecystectomy (LC) to achieve clear visualization of the extrahepatic bile duct, providing real-time visual guidance for surgeons. Although numerous studies have confirmed that the use of ICG fluorescence imaging technology in LC effectively reduces the risk of bile duct injury (BDI), the retention of ICG within the liver generates intense background fluorescence, which undoubtedly increases the difficulty of accurately identifying the bile ducts from the hepatic fluorescence background. Therefore, how to precisely control the dosage of ICG before surgery to ensure optimal visualization of the extrahepatic bile ducts remains a critical issue that needs to be explored and resolved. This study explores the fluorescence imaging efficacy of different doses of ICG within a time window of 0.5 to 3 hours during the surgical process. The aim is to determine the optimal dosage through comparative analysis, providing valuable reference for clinical practice.
