Summary

This study tests a robotic bronchoscope to inject a dye near small lung nodules before they are removed surgically. The dye helps surgeons see the nodule during operation, making removal more accurate. Fifty patients with hard-to-find nodules will be enrolled, and researchers will measure how often the dye is placed correctly and how well the surgery goes. The goal is to improve success rates and reduce complications.

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 (ICG) dye mixed with iodinated contrast
What this could lead to: If successful, this technique could make lung nodule removal more precise and reduce the need for more extensive surgery.
What could go wrong: This is a small, early-stage study with only 50 participants, so results may not apply to all patients. Risks include bleeding, pneumothorax, or allergic reaction to the dye.
