How Is Colonic Diverticular Bleeding Diagnosed?
Published: Jun 02, 2024
Colonic diverticular bleeding is a serious condition that requires precise diagnosis. Learn about the tests used to identify this type of bleeding.
Colonoscopy: The Go-To Test
A colonoscopy is the preferred method for diagnosing colonic diverticular bleeding. This procedure involves a camera that examines the inside of the colon, allowing doctors to locate the source of bleeding. It not only helps confirm the diagnosis but can also be used to treat the bleeding source.
CT Angiography for Severe Cases
When patients experience severe bleeding, CT angiography becomes essential. This is a quick imaging test that helps locate the bleeding without the need for bowel preparation. It's especially useful for identifying active bleeding sources in unstable patients.
Other Diagnostic Methods
In some situations, tagged red blood cell scans might be used, though they're less common. These scans help trace bleeding by tagging blood cells, but are often time-consuming and not widely available.
