Introduction: 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.
Material And Methods: 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.
Results: 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.
Conclusions: 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.

Both photothermal therapy (PTT) and chemodynamic therapy (CDT) are designed to focus their antitumor effect on only the tumor site, thereby minimizing unwanted severe damage to healthy tissue outside the tumor. However, each monotherapy is limited in achieving complete tumor eradication, resulting in tumor recurrence. The combination of multiple therapies may help to overcome the limitations of single therapy, improve the chances of complete tumor eradication, and reduce the risk of recurrence.

Objectives: The advantages of indocyanine green (ICG) fluorescence cholangiography have been emphasized, but its disadvantages remain unclear. This study investigated the advantages and disadvantages of this modality, particularly the optimal timing of administration of ICG fluorescence.
Design: This was a retrospective analysis of prospectively collected patient data.

Indocyanine green (ICG) is a water-soluble green substance that is detectable through infrared cameras and emits greenish light. Approved for medical use in the 1950s, ICG has gained prominence as a real-time visualization tool. Widely recognized as a generally safe substance, ICG is applied in diverse fields.

Fluorescence imaging, a highly sensitive molecular imaging modality, is being increasingly integrated into clinical practice. Imaging within the second near-infrared biological window (NIR-II; 1,000 to 1,700 nm), also referred to as shortwave infrared, has received substantial attention because of its markedly reduced autofluorescence, deeper tissue penetration, and enhanced spatiotemporal resolution as compared to traditional near-infrared (NIR) imaging. Indocyanine green (ICG), a US Food and Drug Administration-approved NIR fluorophore, has long been used in clinical applications, including blood vessel angiography, vascular perfusion monitoring, and tumor detection.

Surgery, especially if minimally invasive, still plays a role in the diagnosis of suspect lymphoproliferative lesions in challenging locations such as the retroperitoneum. Fluorescence guidance may help in such cases facilitating the visualization of highly vascularized lesions. Our recent experience with a 71-year-old woman with retroperitoneal lymphadenopathy and suspected lymphoma supports this hypothesis.
