NCT ID NCT06871579
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new device called the esophageal string test (EST) to diagnose H. pylori, a stomach bacteria that can cause ulcers and cancer. Participants swallow a capsule with a string inside that collects stomach fluids. Researchers compare the results to standard tests. The study involves 25 adults with persistent H. pylori infection and aims to see if the EST can detect the bacteria and antibiotic resistance genes.

Active substance
Esophageal string test (EST) device
What this could lead to
If successful, this could provide a simpler, less invasive way to diagnose H. pylori infection and detect antibiotic resistance.
What could go wrong
This is a very small pilot study (25 people) testing feasibility, not effectiveness. The string test may be less accurate than standard methods or uncomfortable for patients.
