About this trial
The goal of this observational study is to evaluate the diagnostic value and safety of capsule endoscopy in patients with gastrointestinal bleeding. The main questions it aims to answer are:
What is the overall detection rate of bleeding lesions using capsule endoscopy? What is the completion rate of capsule endoscopy, and how long does it take for the capsule to pass through the stomach and small intestine? What adverse events (such as capsule retention) occur during or after the procedure?
Participants who underwent capsule endoscopy for gastrointestinal bleeding at Changhai Hospital between January 2021 and December 2025 will:
Have their existing medical records (including endoscopy reports, procedure notes, and follow-up records) reviewed by researchers Have their personal information anonymized and protected Not be required to undergo any additional tests, procedures, or visits This is a retrospective study that only analyzes previously collected data. No new interventions or patient contact is involved.
