TRANSCRIPT
Upper GI Bleed
James PeerlessApril 2011
Introduction
• Incidence of 100/100 000 population per year (UK & USA)
• >80% occur as acute admissions• ‘Hospital-acquired’– Critically ill patients– Prolonged NG tube– Drug Rx
• Associated with high rate of mortality and long ICU stay
Objectives
• Definitions• Anatomy• Sources of Bleeding• Presentation• Assessment• Management
DefinitionsUpper GI TractThe oral cavity, pharynx, oesophagus, stomach & proximal duodenum
HaematemesisThe act of vomitting blood; swallowed or that arisen from the bleeding within the upper GI tract
MelaenaBlack discoloured faeces due to the presence of partly-digested blood from the upper GI tract
Anatomy

Causes
Varices
• Secondary to portal hypertension
• Dilated collateral veins formed at G-Oe junction
• These portosystemic anastomoses are superficial and prone to rupture
• High pressure veins in a hyperdynamic circulation
Presentation
• Active bleeding• History of haematemesis• Melaena• Shock/hypotension/collapse• Anaemia
Acute Management
Supportive
• Resuscitation– A B C
• History & Examination• Recruit help• Investigations• Continuous monitoring• Blood products• Correction of coagulopathy
Corrective
• Medical• Balloon tamponade• Endoscopy• Surgical
Assessment
• Acute Assessment• History & Examination• Is the airway safe?• Is the patient at risk of further events?
Identifying Risk
• Rockall Score
Rockall Criteria
Rockall Score0 1 2 3
Age <60 60-79 >80
Shock No shock HR >100 HR >100, SBP <100
Comorbidity Cardiac failure, ischaemic heart disease
Renal failure, liver failure, disseminated malignancy
Diagnosis Mallory Weiss, no lesion, no stigmata of recent haemorrhage
All other diagnoses
Malignancy of upper gastrointestinal tract
SRH (Endoscopy)
None, or dark spot
Fresh blood, adherent clot, visible or spurting vessel

Rockall TA, Logan RF, Devlin HB, Northfield TC (1996) Risk assessment after acute upper gastrointestinal haemorrhage. Gut 38:316 – 21
Scoring Systems
• Rockall Score• Forrest Classification– Active haemorrhage– Signs of recent haemorrhage– Lesions without active bleeding
• Glasgow-Blatchford Score– Scored on Hb, urea, BP,
presentation/comorbidities (no endoscopy)
Management Pathway
Oesophagogastroduodenoscopy
• Offers diagnostic information and opportunity for therapeutic intervention
• Scoping within 24 hours has a proven reduction in rebleed, mortality and length of admission
• For ulcers:– Adrenaline injection (temporary efect)– Diathermy/haemocoagulation– Endocscopic clips
Variceal Bleeding
• Endoscopy is the definitive treatment of choice for variceal bleed
Drugs & Secondary MX
Sengstaken-Blakemore Tube
Sengstaken-Blakemore Tube
Linton-Nachlas Tube
TIPSS
• Transjugular Intrahepatic Portosystemic Shunt• Radiologically guided stent– Drilled through the liver and connects the portal
and hepatic vein• Available in specialised units• Complications– Thrombosis (10%)– Bleeding– Infarction
Summary
• Hidden clinical picture• Supportive and Corrective Management• Endoscopic therapy mainstay of treatment• Risk of rebleeding remains high – keep
monitoring the patient!
