Summary
This study tested whether a green dye called indocyanine green (ICG) works as well as standard contrast dye for seeing bile ducts during gallbladder removal surgery.

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

Indocyanine green (ICG) dye
What this could lead to
If successful, this could make bile duct imaging during gallbladder surgery faster and safer, reducing the risk of bile duct injury.
What could go wrong
This is a completed, moderate-sized trial, but the dye may not always provide clear images in inflamed tissue, and it does not test a new treatment for the disease itself.
