Capsule endoscopy study for GI bleeding
Part of Digestive system clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You had symptoms of gastrointestinal bleeding (like vomiting blood, black or bloody stools, or hidden blood in stool)
- You had a magnetic capsule endoscopy at Chang Hai Hospital between January 2021 and December 2025
- You do not have a blocked or narrowed intestine, severe asthma, swallowing problems, or stomach paralysis
- You do not have a pacemaker, cochlear implant, or other non-MRI-safe implanted device
- You are not pregnant and do not need an MRI before the capsule is passed

Other trials that look related to this one.
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 wireless optical sensor capsule that you swallow to find the source of bleeding in your upper stomach or food pipe. It may help doctors diagnose upper gastrointestinal bleeding without a standard endoscopy tube.
This trial uses a special capsule with a magnet to find where bleeding is happening in the stomach or intestines for people who are on antiplatelet drugs (like aspirin or clopidogrel) and have non-bloody vomiting or black stools. If you've been on these drugs for at least two weeks and are stable enough for the procedure, the capsule may help doctors locate the exact bleeding spot.
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 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.
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.
