Summary

This study looked at 416 people who had left-sided colon surgery. A few days after surgery, each person got both a CT scan and an endoscopy to check for leaks where the colon was reconnected. The goal was to see which test is more accurate at finding these leaks. Results help doctors choose the best way to catch complications early.
