    Massive rectal bleeding can signal jejunal diverticula, a rare but serious cause. Angiography is key for locating these difficult-to-find bleeding points in the small intestine.

    Area of Science:

    • Gastroenterology
    • Interventional Radiology

    Background:

    • Jejunal diverticula are an uncommon source of massive gastrointestinal bleeding.
    • Bleeding often presents as lower gastrointestinal hemorrhage, mimicking other conditions.

    Observation:

    • Three patients presented with life-threatening rectal hemorrhage due to bleeding jejunal diverticula.
    • Angiography successfully localized the bleeding source in all patients.
    • Vasopressin infusion was ineffective for hemostasis in two patients.

    Findings:

    • Jejunal diverticula can cause significant lower GI bleeding.
    • Angiographic localization is crucial for surgical planning due to the occult nature and proximal location of these diverticula.
    • A normal small intestine series does not rule out jejunal diverticula as a bleeding source.

    Implications:

    • Early diagnosis and precise localization via angiography are vital for managing massive GI bleeding from jejunal diverticula.
    • Surgical intervention may be necessary when less invasive methods fail.
    • Clinicians should consider jejunal diverticula in the differential diagnosis of obscure massive lower GI bleeding.
