This clinical trial is focused on studying the use of a special imaging technique during surgery for patients with colorectal cancer. The trial involves a substance called indocyanine green, which is used to help surgeons see blood flow in tissues during operations. This technique is known as intraoperative fluorescence angiography. The main goal of the study is to see if using this method can help reduce the risk of a complication called anastomotic leakage, which can occur after surgery when the connection between two parts of the intestine leaks.

Participants in the study will undergo surgery for colorectal cancer, where the surgeons will use the indocyanine green to check the blood flow in the area where the intestines are joined together. This is done to ensure that the tissues are healthy and well-supplied with blood, which may help prevent leaks. The study will monitor patients for 90 days after their surgery to see if this method helps reduce complications.

Throughout the study, researchers will also look at other factors, such as any changes made during surgery based on the blood flow assessment, the need for additional procedures, and the overall recovery of patients, including their quality of life and time spent in the hospital. The study aims to provide valuable information on whether this imaging technique can improve outcomes for patients undergoing colorectal cancer surgery.
