- W4234549630 abstract "•. Gastrointestinal bleeding is a common condition. •. Endoscopic assessment and management is the first line therapy particularly for upper gastrointestinal (GI) tract. •. CT angiography has emerged as a sensitive technique that allows accurate localisation throughout GI tract. •. Embolisation is an effective therapy most commonly used in the lower GI tract. •. Rebleeding will occur in up to a fifth of patients and may be treated by repeat embolisation. Acute gastrointestinal (GI) haemorrhage is a common condition that can be life threatening. The majority of patients will settle with conservative management. Patients who have persistent bleeding and haemodynamic compromise will require urgent investigation. Upper GI haemorrhage is usually investigated by endoscopy and therapeutic endoscopic techniques will control the bleeding in many patients. Patients with upper GI bleeding who fail endoscopic therapy should undergo CT scanning for initial localisation and confirmation of the active bleeding. Treatment by embolisation may be possible although there is a rich collateral supply. Lower GI bleeding is more frequently investigated and treated by radiological means. CT angiography is invaluable as an initial test to identify and localise active bleeding. Patients with a negative CT scan can be managed conservatively. Lower GI embolisation is a safe technique although there is a significant risk of rebleeding, which can be retreated with embolisation." @default.
