    Transcatheter embolotherapy for colonic bleeding can cause acute colonic mucosal necrosis in a small percentage of patients. However, this risk is lower than emergency surgery and offers an alternative to vasopressin infusion for managing lower gastrointestinal bleeding.

    Area of Science:

    • Gastroenterology
    • Interventional Radiology

    Background:

    • Transcatheter embolotherapy is a treatment for lower gastrointestinal bleeding.
    • Vasopressin infusion is an alternative transcatheter therapy with limitations.

    Observation:

    • Three out of 23 patients developed acute colonic mucosal necrosis after transcatheter embolotherapy for colonic hemorrhage.
    • Complications of vasopressin infusion include continued bleeding and contraindications in patients with coronary disease.

    Findings:

    • Transcatheter embolotherapy carries a risk of acute colonic mucosal necrosis.
    • The risks associated with embolotherapy are lower than those of emergency surgery for hemorrhage.

    Implications:

    • Transcatheter embolotherapy is a recommended option for colonic bleeding when vasopressin is contraindicated, ineffective, or followed by rebleeding.

  • This highlights the importance of risk-benefit assessment in choosing between embolotherapy and vasopressin infusion.
