Bypass without surgery: new scope procedure helps cancer patients eat again
NCT ID NCT05644951
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new procedure that uses an endoscope to create a bypass around a stomach blockage caused by advanced cancer. The goal was to help people eat and drink without major surgery. Fifty-one participants with inoperable cancer and severe blockage were enrolled. The procedure uses a special device to connect the stomach directly to the small intestine, bypassing the blocked area.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Hot AXIOS system (a device used to create a bypass between the stomach and small intestine)
- What this could lead to
- If successful, this procedure could offer a less invasive way to relieve stomach blockage in people with advanced cancer, allowing them to eat and drink more easily.
- What could go wrong
- This was a small, single-arm study with no comparison group, so results may not apply to everyone. The procedure carries risks like bleeding, infection, or device-related problems.
