Background: Colon cancer is known as one of the most prevalent malignancies in world. This well-known pathology requires accurate lymph node dissection to achieve effective staging and improved treatment outcomes. Indocyanine green fluorescence imaging has been used a new technique for enhancing visualization during surgical intervention. The high rates local recurrence colon patients require innovative methods improve lymphatic mapping dissection. review evaluates clinical utility efficacy ICG accuracy surgery. Materials methods: A systematic search was conducted October 2024 (last day consulting database 16 November) across Web Science, Scopus, PubMed identify studies published from 2020 onwards focusing on use indocyanine surgeries. terms were “indocyanine green”, “ICG”, “fluorescent imaging”, “near-infrared “colon cancer”, “colorectal carcinoma”,” neoplasms”, “surgery”, “surgical procedure”, resection”, precision”. followed PRISMA guidelines. records underwent two-phase independent screening process by authors, first based title abstract, full record evaluation. Articles excluded following certain exclusion criteria: non-human studies; restricted access publications; other publication type than article (review, meta-analysis, questionnaire-based study, case report, etc.), diseases or that focused metastasis cancer; foreign language (non-English); no data interest current review; rectal grouped cancer.

Indocyanine green (ICG), a near-infrared (NIR) fluorescent dye with unique photoluminescent properties, is helpful tool in many medical applications. ICG produces fluorescence when excited by NIR light, enabling accurate tissue visualization and real-time imaging. This study investigates the fundamental processes behind ICG's photoluminescence as well its present possible applications treatments diagnostics. Fluorescence-guided surgery (FGS) has been transformed capacity to visualize tumors, highlight blood flow, facilitate lymphatic mapping, all of which have improved surgical accuracy patient outcomes. Furthermore, being studied for new therapeutic approaches, like photothermal therapy, light can activate target destroy cancer cells. We go over benefits drawbacks qualities contexts, current studies that focus on improving effectiveness, security, adaptability. More precise disease detection, monitoring, tailored therapy options across variety specialties are made ongoing advancement ICG-based imaging methods therapies. In main part our work, we strive take into account latest reports; therefore, used clinical articles going back 2020. However, sake theoretical part, oldest article us from 1995.
