Leak check during bowel surgery may prevent serious complications

NCT ID NCT06865638

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at whether testing the surgical connection (anastomosis) for leaks right after colorectal cancer surgery can reduce complications like leakage, bleeding, or infection. About 264 patients will be randomly assigned to receive leak testing or not. The goal is to see if this simple check during surgery improves outcomes within 30 days.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Intraoperative leak testing (using gastroscopy, air, and methylene blue)

What this could lead to

If successful, this could show that routine leak testing during colorectal cancer surgery reduces serious complications like anastomotic leakage, potentially becoming a standard practice.

What could go wrong

This is a relatively small, early-stage trial (264 participants) comparing two surgical techniques, so results may not be definitive or widely applicable. The procedure itself carries minor risks like discomfort or allergic reaction to methylene blue.
