Clip or coil? new study tests best way to stop stomach bleeding
NCT ID NCT04902248
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two procedures for people whose upper stomach bleeding continues after initial treatment. One uses an endoscope to place a special clip on the bleeding spot; the other uses X-ray guidance to inject tiny coils into the bleeding artery. The trial will enroll 236 adults and track whether bleeding stops, how much blood is needed, and hospital stay length.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- over-the-scope clip (OTSC) device
- What this could lead to
- If successful, this could show that using an endoscopic clip is as effective as embolization for stopping stubborn stomach bleeding, potentially offering a less invasive first option.
- What could go wrong
- This is a relatively small, early-stage comparison. The two methods may prove equally effective, or one may be clearly better. Bleeding can still recur, and both procedures carry risks like infection or injury.
