Summary

This study tested whether a green dye called indocyanine green (ICG) combined with 4K cameras can help surgeons find liver tumors during keyhole surgery. 45 adults having liver surgery took part. The dye makes tumors and bile leaks glow under special cameras, which may help surgeons remove all the cancer while leaving healthy tissue intact.

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
What this could lead to
If successful, this technique could help surgeons see small liver tumors more clearly during keyhole surgery, potentially leading to better removal of cancer.
What could go wrong
This is a small, early feasibility study with only 45 participants, so results may not apply to all patients. The dye can cause allergic reactions in rare cases.
