Preliminary application of indocyanine green fluorescence imaging in postoperative gastrointestinal fistula

Abstract

We describe a case using indocyanine green (ICG) fluorescence imaging for diagnosis of postoperative gastrointestinal fistula. When the fistula is very large, both indocyanine green and methylene blue can be found in the postoperative drainage. After treatment, when the leak became small, only ICG fluorescence imaging continued to be demonstrated. ICG fluorescence imaging is likely to prove to be a safe and effective method of examination, and one that is very practical and easy to execute for the diagnosis of postoperative gastrointestinal fistula.
