Core Tip
Core Tip: Indocyanine green (ICG)’s unique absorption and emission spectrum allows its wide application in gastrointestinal surgery. The fluorescence cholangiography property of ICG is widely used in hepatobiliary surgery to identify bile ducts. Its angiography property is used in liver surgery for tumor identification and to facilitate anatomic liver resection. Also, the angiography function is helpful in luminal surgeries to assess bowel perfusion. The limitations of ICG fluorescence highlighted in the present review could guide future research on ICG in gastrointestinal surgery.
