Endoscopy is the primary diagnostic and therapeutic modality for the vast majority of patients with haemorrhage of the upper or lower digestive tract. In many hospitals, surgery is the therapy of choice when endoscopy fails or is impossible. In patients who have considerable co-morbidity and who are actively bleeding from the digestive tract, surgery is associated with a relatively high morbidity and mortality. Angiographic embolisation for haemorrhage from the upper or lower digestive tract is effective, with success rates varying from 50 to 90%. The risk of ischaemic complications of the procedure is acceptably low ( <5%). Angiography is not very time-consuming and does not preclude subsequent surgical treatment ifangiographic embolisation does not succeed. However, performing embolisation requires skill and experience and the procedure is not available everywhere. Angiographic embolisation is a valuable alternative to surgery and should be considered in all patients with haemorrhage of the digestive tract who cannot be treated by means of endoscop
