Testing a camera swallow exam for recent upper gut bleeding
Part of Digestive system clinical trials.
This study tests whether a “videocapsule endoscopy” (a small camera you swallow) can find the cause of upper gastrointestinal bleeding when a first scope doesn’t show active bleeding. It may help doctors locate hidden bleeding sources and guide treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You had a new, recent episode of upper gut bleeding within about 48 hours of going to the ER, with blood test change (hemoglobin drop of at least 20 g/L)
- You can understand and sign consent
- At the time of consent, your vital signs are stable (blood pressure above 100/60 and/or pulse under 110)
- Your first stomach camera (gastroscopy) did not show active bleeding or a clear bleeding source

This trial tests if a quick endoscopic exam of the upper digestive tract helps people who come to the hospital with maroon-colored or bloody stools. It may find the source of bleeding and guide treatment.
This study compares how accurately a new AI tool reads capsule endoscopy videos (a small camera you swallow to look inside your digestive tract) versus standard reading methods. No new procedures will be done—researchers will only re-examine videos already taken.
This trial studies whether a swallowable camera capsule can detect bleeding in the small intestine when standard scopes (up the stomach and through the colon) haven’t found the cause. If your bleeding source is suspected but not seen on those tests, this could help identify where the bleeding is coming from.
This trial tests a swallowable camera (capsule endoscopy) to look inside the gut in people with severe ongoing rectal bleeding. It may help doctors find the bleeding source when symptoms are serious and blood counts are dropping.
This study looks back at records of people who had a small camera in a pill (capsule endoscopy) to find the cause of bleeding in the stomach or intestines. If you had this test at Chang Hai Hospital between 2021 and 2025 for bleeding symptoms, your data may help doctors learn more.
This trial tests a new type of 'capsule' (a small pill with a camera) that doctors can guide with a magnet to look for the source of upper digestive tract bleeding. It's for people who come to the emergency room with signs of bleeding from the stomach or esophagus and are stable enough for the exam.
