Fluorescence angiography with indocyanine green (ICG) to evaluate anastomosis in colorectal surgery: where does it have more value?

ICG-FA leads to significantly more changes in the resection line in case of left hemicolectomy followed by anterior resection. FA is a promising optical imaging technique to reduce the AL incidence after colorectal procedures. To confirm this data, further studies with wider sample size and with an objective evaluation of the anastomotic perfusion are required.
