New Light-Based imaging could replace dye in surgery to prevent dangerous leaks
NCT ID NCT06222645
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new imaging technique called iPPG, which uses light to measure blood flow, against the standard method using a green dye (ICG) during gastrointestinal surgery. The goal is to see if iPPG can predict and prevent anastomotic leaks—a serious complication where the surgical connection leaks. About 200 adults having elective bowel surgery will be randomly assigned to one of the two imaging methods.
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 and photoplethysmography (iPPG) imaging
What this could lead to
If successful, this could provide a safer, dye-free way to assess blood flow during surgery, potentially reducing complications like anastomotic leaks.
What could go wrong
This is a single-center trial with 200 participants, so results may not apply broadly. The new iPPG method is still experimental and may not be as accurate as the standard ICG approach.
