Gastrointestinal Angiodysplasia When Endoscopic Therapy Has Failed to Control Bleeding

Gastrointestinal angiodysplasia is managed through several approaches, including endoscopic therapy, surgical resection, or transcatheter angiography and intervention. When the endoscopic route has been attempted and has not achieved the required hemostatic goals, a next-line management step is indicated.

Previous Treatment — Failure Condition

This protocol applies after endoscopic therapy — the second-line approach used to obliterate malformed vessels and achieve hemostasis — has not succeeded in stopping active bleeding or preventing rebleeding, and hemoglobin or hematocrit have continued to fall beyond accepted thresholds.

Clinical Goals at This Stage

The management objectives remain cessation of active bleeding and prevention of rebleeding, with stabilisation of hemoglobin (no further drop beyond 1 g/dL) and hematocrit (no further drop beyond 5%).

Approach at This Line

The next step involves either a surgical or catheter-based vascular approach to address the source of bleeding. The specific pathway, selection criteria, and sequencing are detailed in the full protocol.

Management is mainly assessed based on the cessation of bleeding, prevention of rebleeding, and improvement in a person's clinical status.

Stability of hemoglobin/hematocrit levels: no further drop beyond 1 g/dL for hemoglobin and 5% for hematocrit following the intervention.
