Diagnosis of upper GI bleeding in cirrhosis Endoscopy as soon as resuscitation adequate It is a high risk endoscopy - adequate support staff (suction) - assess risk of aspiration - pulse oximetry - nasal oxygen - will need endotracheal intubation/ga in several cases Look at fundus, other lesions NB 50% DGH do not have an adequately supported on call system
Rapid imaging in UGI bleeding in cirrhosis Establish patency portal vein Look for hepatocellular carcinoma Use ultrasound/ doppler
