Summary

This study looked at whether using a special dye (indocyanine green) during laparoscopic surgery for colon or rectal cancer can help surgeons see blood flow in real time and reduce the risk of a dangerous leak where the bowel is reconnected. Researchers compared 115 patients who had the dye with a similar group from the past who did not. The goal was to see if the dye leads to fewer complications like leaks or strictures.
