Surg Innov. 2022 Aug;29(4):479-487. doi: 10.1177/15533506211072678. Epub 2022 Mar 1.


Fluorescence imaging in colorectal surgery is considered a novel predominantly intraoperative method of ensuring a greater surgical success. The use of fluorescence is linked to advanced tumor visualization and projection of its lymphatics, both vessels and nodes, which results in a higher chance of achieving a total excision. Additionally, iatrogenic complications prove to be reduced using fluorescence during the surgical excision. The combination of fluorescence and artificial intelligence to better facilitate oncological surgery will soon become an established approach in operating rooms worldwide.

Keywords: colorectal surgery; fluorescence imaging; fluorophore; indocyanine green; near- infrared light.
