Anastomotic leakage remains a major complication after colorectal cancer surgery. Indocyanine green fluorescence angiography (ICG-FA) allows real-time intraoperative assessment of bowel perfusion; however, its clinical impact remains controversial. This prospective single-center observational study evaluated the association between intraoperative use of ICG-FA and postoperative outcomes in patients undergoing laparoscopic sigmoid or rectal cancer surgery. Outcomes of patients assessed with ICG-FA were compared with those of a historical control cohort treated without fluorescence imaging.
