Current status of application and research on indocyanine green fluorescence imaging in laparoscopic colorectal cancer surgery

［Abstract］Indocyanine green fluorescence imaging (ICG-FI) has been widely applied in various surgical fields. In colorectal cancer surgery, it is primarily used for tumor localization, lymph node tracing, and anastomotic blood perfusion assessment, providing crucial reference information for surgical planning and execution, and thereby enhancing surgical outcomes and patient prognosis. Based on the literature review and the clinical practice experience of the authors’ team, this article summarizes the current status of application and research on ICG-FI in laparoscopic colorectal cancer surgery and discusses relevant issues in clinical application.
