Abstract: Indocyanine Green (ICG) fluorescence imaging has revolutionized the surgical management of colorectal cancer. Initially developed as a diagnostic dye for cardiovascular and hepatic output monitoring in the 1950s, ICG has found groundbreaking applications in fluorescence-guided surgery, particularly in oncological procedures, in the XXI century. By enhancing the visualization of vascular perfusion and lymphatic drainage patterns, ICG fluoroscopy has improved the precision of tumor resections and bowel reconstruction, minimized complications, and improved patient outcomes. This chapter explores the historical development, mechanisms of action, and clinical applications of ICG in colorectal cancer surgery, emphasizing its role in assessing bowel perfusion and identifying sentinel lymph nodes. Furthermore, we discuss the integration of ICG into minimally invasive and robotic-assisted techniques, highlighting its potential to transform surgical strategies and decision-making. While evidence supports ICG's effectiveness in reducing anastomotic complications, larger multicenter trials are still necessary to validate its benefits fully. As technologies advance, the integration of artificial intelligence into fluorescence imaging promises even greater precision in real-time tissue perfusion analysis. The future of digestive oncology surgery lies in adopting innovative tools like ICG, ensuring improved surgical accuracy, patient safety, and long-term survival rates.
