Indocyanine green (ICG) lymphography can be performed to obtain realtime fluorescent images of the thoracic duct (TD). The injection of ICG into the inguinal nodes usually is ultrasound-guided. Our hypothesis was to simplify the ICG administration until making it executable by unqualified personnel without ultrasound guidance.
From October 2019 to October 2021 we enroled 18 patients. ICG was injected with a 25 Gauge needle in the subcutaneous tissue of the inguinal region bilaterally 14-16 h before surgery.
The TD was visualised in every case considered. The easy switching between fluorescence and white light visualization facilitated the identification and dissection of the TD avoiding involuntary injuries.
The simplified ICG administration to identify TD during oesophagectomy is easy to perform, does not require specifically trained staff, is not time demanding and has comparable results to the procedure performed under ultrasound guide.
可进行吲哚菁绿（ICG）淋巴造影以获取胸导管（TD）的实时荧光图像。通常在超声引导下将ICG注入腹股沟淋巴结。我们的假设是简化ICG给药方式，直至使其可由非专业人员在无超声引导的情况下进行操作。
2019年10月至2021年10月，我们纳入了18例患者。在手术前14 - 16小时，用25号针头将ICG双侧注射到腹股沟区的皮下组织中。
在每例纳入的病例中均观察到了胸导管。荧光与白光可视化之间的轻松切换有助于胸导管的识别和解剖，避免了意外伤害。
在食管切除术中用于识别胸导管的简化ICG给药方式易于实施，无需专门培训的人员，不耗时，且与超声引导下的操作结果相当。
