Could saving a tiny artery prevent deadly leaks after colon surgery?

This study looks at whether preserving the left colic artery during colon or rectal cancer surgery helps keep the remaining colon well-supplied with blood. Surgeons will temporarily clamp the main artery and use a green dye to measure blood flow. The goal is to see if this technique can reduce the risk of anastomotic leaks, a serious complication that occurs in up to 15% of cases. Fifty adults with colorectal or ovarian cancer are being enrolled.
