A Special Dye May Help Reduce Complications After Colorectal Cancer Surgery

One of the most serious risks after colorectal cancer surgery is an anastomotic leak, which happens when the connection between two sections of the bowel does not heal properly. This can lead to infection, more surgery, and longer recovery times.

A new study reviewed 25 studies with nearly 7,000 patients to see if using a special imaging technique called indocyanine green (ICG) fluorescence angiography can make surgery safer.

ICG is a harmless dye injected during surgery that glows under special light. It helps surgeons clearly see blood flow to the bowel, ensuring that the tissue being connected is healthy and has enough blood supply to heal well.

The results were impressive. Compared to patients who had surgery without ICG, those who received ICG had:
– 50% fewer anastomotic leaks
– 68% fewer serious leaks causing symptoms
– Fewer overall complications
– Fewer repeat surgeries
– Shorter hospital stays

This means that ICG can give doctors a clearer view during surgery and reduce the risk of dangerous complications afterward.

While not yet used everywhere, this technology is becoming more common and may soon be part of standard care for colorectal surgery. Patients preparing for surgery can ask their doctor if ICG fluorescence angiography is available and suitable for them.
