Can Water-Filled stomach surgery spare patients from scalpel?
NCT ID NCT07728292
First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time
Summary
This trial tests whether a procedure called underwater endoscopic mucosal resection (UEMR) can safely and completely remove small type I gastric neuroendocrine tumors (5-9 mm). Instead of traditional surgery, doctors fill the stomach with saline and use a snare to cut out the growth while it floats. The study will check how often the tumor is removed with clean edges and track any complications or regrowth over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- underwater endoscopic mucosal resection (UEMR) — a procedure that removes small stomach tumors while the organ is filled with saline
- What this could lead to
- If successful, this technique could offer a less invasive, effective way to remove small stomach neuroendocrine tumors without surgery.
- What could go wrong
- This is a small, single-center study with only 60 participants. The procedure may not achieve complete tumor removal in all cases, and risks include bleeding or perforation.
