Summary

This trial tests two techniques used during lung segment removal surgery to identify the boundary between lung segments. In each participant, both methods—an injected green dye and carbon dioxide gas—are used during the same operation, and the borders they identify are compared. The goal is to see if the two approaches agree, which could help surgeons remove tumors with safer margins while sparing healthy tissue.

What this could mean

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

Active substance: Indocyanine green fluorescence imaging and carbon dioxide inflation-deflation
What this could lead to: If the two methods agree, surgeons could rely on either technique with confidence, potentially improving surgical precision and preserving more healthy lung tissue.
What could go wrong: The trial is small and early, and the two techniques may not always match. Individual patient anatomy or tumor location could limit how well the findings apply to everyone.
