研究目的:

吲哚菁绿荧光成像技术已成为腹腔镜胆囊切除术中辅助胆道显影的重要工具。然而,ICG经肝脏代谢后会在肝实质滞留,产生高背景荧光,从而降低目标胆管与周围肝脏组织的对比度,影响术中对关键结构的辨识。目前,临床上关于ICG的最佳术前给药时机与剂量尚无统一标准,方案的多样性可能导致显影效果的巨大差异。本研究旨在填补这一空白,通过严谨的随机对照试验设计,同步分析时间与剂量两个因素的独立效应及其交互作用,以期建立一个基于循证医学的、可重复性高的优化给药方案,最终实现以最少的ICG用量达到最清晰的术中导航效果。  

Objectives of Study:

Indocyanine green fluorescence imaging has emerged as a crucial tool for intraoperative biliary tract visualization during laparoscopic cholecystectomy. However, after hepatic metabolism, ICG tends to accumulate in the liver parenchyma, resulting in high background fluorescence that diminishes the contrast between the target bile ducts and surrounding hepatic tissues, thereby compromising the identification of critical anatomical structures during surgery. Currently, there is no standardized protocol in clinical practice regarding the optimal timing and dosage for preoperative ICG administration. The variability in existing regimens may lead to significant differences in imaging outcomes. This study aims to address this gap by employing a rigorous randomized controlled trial design to simultaneously evaluate the independent effects and potential interactions of both timing and dosage factors. The ultimate goal is to establish an evidence-based, highly reproducible optimized administration protocol that achieves the clearest possible intraoperative navigation with minimal ICG usage.

药物成份或治疗方案详述:

本研究方案旨在系统优化腹腔镜胆囊切除术中吲哚菁绿荧光成像的术前给药策略。该研究将同时探讨ICG的注射时间(0-3小时、3-6小时、6-9小时、9-12小时)与剂量(0.25毫克、0.50毫克、1.00毫克、2.50毫克)两个关键因素对胆道显影质量的独立与交互影响。通过建立广义线性模型,研究旨在为临床确定一个能够最大化胆管-肝脏对比度、同时抑制背景荧光干扰的最佳给药“时间-剂量”组合。该研究将在石家庄市人民医院开展,计划纳入240名拟行荧光腹腔镜胆囊切除术的患者。研究成果将通过主、客观指标综合评估,以提升手术导航的精确性与安全性。 

Description for medicine or protocol of treatment in detail:

This study protocol aims to systematically optimize the preoperative administration strategy of indocyanine green (ICG) fluorescence imaging for laparoscopic cholecystectomy. The investigation will simultaneously examine the independent and interactive effects of two critical factors—ICG injection timing (0–3 hours, 3–6 hours, 6–9 hours, and 9–12 hours before surgery) and dosage (0.25 mg, 0.50 mg, 1.00 mg, and 2.50 mg)—on biliary tract imaging quality. By constructing generalized linear models, the study seeks to identify an optimal time-dose combination that maximizes bile duct-to-liver contrast while minimizing background fluorescence interference. The trial will be conducted at Shijiazhuang People’s Hospital and plans to enroll 240 patients scheduled for fluorescence-guided laparoscopic cholecystectomy. Study outcomes will be comprehensively evaluated using both subjective and objective criteria to enhance the precision and safety of surgical navigation.

Outcome:

The bile duct-to-liver fluorescence contrast ratio

Type:

Primary indicator

测量时间点:

术中

测量方法:

在术中关键解剖时刻采集静态荧光图像,由一名盲法评估者使用Image J软件,在胆囊管-胆总管连接处及肝右叶前段实质区各随机选取5个点测量灰度值,取平均值后按公式[(CD-CBD均值 - 肝脏均值) / 255]计算对比值。

Measure time point of outcome:

During surgery

Measure method:

During critical anatomical dissection, static fluorescence images were acquired. A blinded evaluator used Image J software to randomly select five measurement points each at the cystic duct–common bile duct junction and the parenchymal area of the anterior segment of the right hepatic lobe. The mean gray-scale intensity values were calculated for each region, and the contrast ratio was determined using the formula: (mean value at CD-CBD junction ? mean value of liver parenchyma) / 255.

指标中文名:

主观显影成功率

指标类型:

主要指标

Outcome:

Subjective success rate of visualization

Type:

Primary indicator

测量时间点:

术中

测量方法:

由主刀医师与第一助手于术中共同评估。成功标准为:肝外胆管轮廓清晰,与肝脏背景对比鲜明,可明确指导手术分离;失败标准为:胆管无法辨识或对比度差,无法提供有效导航。

Measure time point of outcome:

During surgery

Measure method:

The intraoperative assessment was jointly performed by the chief surgeon and the first assistant. Successful visualization was defined as clear delineation of the extrahepatic bile ducts with distinct contrast against the liver background, enabling precise guidance for surgical dissection. Failure was defined as the inability to identify the bile ducts or poor contrast, which provided no effective navigational utility.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用分层区组随机化。随机序列由一名独立的生参与研究人员使用相关软件生成,分层因素为“给予ICG时间”(0-3, 3-6, 6-9, 9-12小时)。在每个时间段内,患者以1:1:1:1的比例被随机分配至0.25 mg、0.50 mg、1.00 mg或2.50 mg四个剂量组之一,每个剂量组计划纳入15例患者。

Randomization Procedure (please state who generates the random number sequence and by what method):

This study employed stratified block randomization. The random sequence was generated by an independent participant using relevant software, and the stratification factor was "ICG time given" (0-3, 3-6, 6-9, 9-12 hours). At each time period, patients were randomly assigned in a 1:1:1:1 ratio to one of four dose groups: 0.25 mg, 0.50 mg, 1.00 mg, or 2.50 mg, with 15 patients planned to be included in each dose group.
