Glow-in-the-Dark dye could make gallbladder surgery safer
NCT ID NCT02702843
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether using a dye called indocyanine green along with infrared light helps surgeons see the bile ducts more clearly during gallbladder removal surgery. Over 600 adults having their gallbladder taken out were randomly assigned to either standard white light or the new infrared technique. The goal was to see if the infrared method improves detection of key bile ducts before and after dissection, which could reduce the risk of accidental injury.
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 dye
What this could lead to
If this technique works better, it could help surgeons avoid injuring bile ducts during gallbladder surgery, making the procedure safer.
What could go wrong
This is a completed study comparing two imaging methods, not a new treatment. The dye may not improve outcomes for all patients, and some people are allergic to iodides.
