Tiny camera may spot hidden bleeding in rare blood disorder
NCT ID NCT04466878
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether using a video capsule endoscopy (a small camera pill) along with standard scopes can better find the source of gut bleeding in people with von Willebrand disease. Researchers reviewed records of 50 patients who had gut bleeding between 2015 and 2017. They also checked if findings from the capsule could predict future bleeding. The goal was to improve diagnosis and management, not to test a new treatment.
