INDOCYANINE GREEN FLUORESCENCE ANGIOGRAPHY IN COLORECTAL SURGERY

Postoperative anastomotic leakage is the most serious complications of colorectal surgery and occurs in 10-15％ of cases of low anterior resection. Although several factors are associated with anastomotic leakage, insufficient blood perfusion is generally considered to be one of the main causes. Indocyanine green (ICG) fluorescence angiography has recently been developed as an intraoperative real-time method to evaluate intestinal perfusion. Although some recent studies have reported that ICG fluorescence angiography has potential benefit in evaluating intestinal perfusion, it remains unclear whether it could reduce the rate of postoperative anastomotic leakage following rectal surgery. Here we review the current litarature published on ICG angiography in colorectal surgery. Further studies are required to confirm the usefulness of ICG fluorescence angiography.
