摘要
Endoscopic injection is widely used for the arrest of active ulcer bleeding and for prevention of re-bleeding from ulcers with visible vessels. Although of proven value in clinical trials, mechanisms of action are unclear; tamponade, vasoconstriction, endarteritis and a direct effect upon the clotting process at the site of the arterial defect have been proposed. Clinical trials show that dilute adrenaline is an effective agent and that the addition of sclerosants or alcohol confirms no extra benefit, yet risks serious side-effects. The best results are associated with injection of fibrin glue or thrombin which stimulate formation of a stable blood clot, The efficacy of injection, thermal modalities such as the heater probe and electrocoagulation using BICAP are comparable. In general, there is an advantage in combining injection with a thermal modality, although this may have merit in patients with severe, active ulcer bleeding. Patients who re-bleed following successful primary haemostatic injection treatment can be considered for further endoscopic intervention, but the decision to undertake a surgical operation or repeat endoscopic therapy is a matter of clinical judgement.
