Initial Evaluation Steps
The first step in diagnosing acute lower GI bleeding involves a thorough medical history and a physical examination. Doctors look for signs of bleeding, such as changes in stool color, and assess the patient's overall stability. Lab tests are also crucial, helping determine if the bleeding might be from the upper GI tract.
Colonoscopy: The Gold Standard
A colonoscopy is often the go-to procedure for diagnosing acute lower GI bleeding. It allows doctors to visually inspect the colon for sources of bleeding and even perform therapeutic interventions. While it requires bowel preparation, its ability to locate and sometimes treat bleeding makes it invaluable.
Other Diagnostic Tools
For patients with severe or ongoing bleeding, additional tools like CT angiography might be used. This imaging test can quickly identify active bleeding sites, helping guide further interventions. However, it involves radiation and contrast dye, so it's used selectively.
