Green dye could help surgeons prevent stomach ulcers after bypass
NCT ID NCT06002906
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a safe green dye, injected during gastric bypass surgery, can help surgeons see blood flow to the new stomach connection. Poor blood flow can lead to ulcers, leaks, or narrowing. The trial involves 300 adults and will follow them for two years to see if using the dye reduces these 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 (a green dye injected into the bloodstream to highlight blood flow during surgery)
What this could lead to
If it works, this dye could help surgeons spot poor blood flow during gastric bypass, potentially lowering the risk of ulcers, leaks, and other complications.
What could go wrong
This is a pilot study, so it's early and small. The dye's benefit is not proven yet, and it may not reduce complication rates in practice.
