Abstract:

Indocyanine green （ICG） fluorescence imaging has been increasingly used in surgical procedures， and in recent years， ICG fluorescence imaging has been gradually applied to gastrointestinal tumor surgery.The main roles include tumor localization， lymph node tracing， anastomotic blood supply assessment， and detection of liver and peritoneal metastases， which further improves the surgical quality of gastrointestinal oncologic surgery and brings benefits to patients.However， the clinical application of ICG fluorescence imaging technology in gastrointestinal surgery has limitations of relatively short-term， lack of standardized specification， and there are still controversies over some of the applications.In this paper，the progress of the application of ICG fluorescence imaging technology in gastrointestinal tumor surgery is reviewed in the light of the relevant literatures at home and abroad.
