Colorectal anastomoses after anterior resection for cancer carry a high risk of leakage. Different factors might influence the correct healing of anastomosis, but adequate perfusion of the bowel is highlighted as one of the most important elements. Fluorescence angiography (FA) is a new technique that allows the surgeon to perform real-time intraoperative angiography to evaluate the perfusion of the anastomosis and hence, potentially, reduce leak rate.

The aim of this study was to evaluate the impact of FA of the bowel on postoperative complications and anastomotic leakage after laparoscopic anterior resection with total mesorectal excision (TME).

FA was performed in all patients undergoing laparoscopic anterior resection with TME for cancer followed by colorectal or coloanal anastomosis …
