下部消化管出血（特に憩室出血）に対するIVR治療戦略

抄録

Acute gastrointestinal bleeding is a cause of death, with mortality rates as high as 8-14%. Thus, it is very important to identify the cause of gastrointestinal bleeding earlier and to stop bleeding more quickly. With lower gastrointestinal bleeding (LGIB), it is often more difficult to detect the bleeding point and stop the bleeding by endoscopy than with upper gastrointestinal bleeding. However, the bleeding point identification rate by contrast-enhanced computed tomography (CT) is extremely high, with a sensitivity of 85.2% and specificity of 92.1%, and the subsequent hemostasis rate is almost 90% for both endoscopy and interventional radiolody. However, the strategy for diagnosis and treatment of LGIB differs by hospital, and the differences depend on hospital function.
We will explain the strategy for the diagnosis and treatment of LGIB, especially diverticular bleeding, with case presentations.
