Computed Tomography-Guided Diagnosis of Massive Cystojejunal Bleeding

Abstract

Acute gastrointestinal bleeding is a serious emergency condition which, without prompt and accurate diagnosis, can lead to severe hemorrhagic shock and death. The initial diagnosis relies on a clinical assessment of the bleeding site. If symptoms such as hematemesis and melena are present, an esophagogastroduodenoscopy (EGD) is typically the first diagnostic procedure. In cases of massive rectal bleeding, a computed tomography scan with angiography (CTA) is often used to identify the source and cause of the bleeding. Multiphasic CTA is the definitive first-line diagnostic standard, enabling prompt diagnosis and crucial pre-procedural planning for endovascular management in massive cystojejunal bleeding.
