Upper GI bleed Flashcards
Common causes of Upper GI bleeding
Peptic ulcer disease (40%)
Gastritis (20%)
Mallory-Weiss tear (10%)
Oesophageal varices (5%)
What is the Rockall score?
prediction of re-bleeding and mortality in patients with upper GI bleed
Initial Rockall score pre-endoscopy
age
shock (BP, pulse)
comorbidities
Final Rockall score post-endoscopy
active bleeding
visible vessel
adherent clot
Pathophysiology of oesphageal varices
Portal HTN → dilated veins at sites of porto-systemic anastomosis: L. gastric and inferior oesophageal veins
30-50% with portal HTN will bleed from varices
Mortality rate of oesphageal varices
25%
- ↑ with severity of liver disease.
Prehepatic causes of portal HTN
pre-hepatic: portal vein thrombosis
Hepatic causes of portal vein HTN
cirrhosis, schistosomiasis, sarcoidosis
Post hepatic causes of portal vein HTN
Budd-Chiari, RHF, constrict pericarditis
1st and 2nd line prevention of bleed in oesphageal varices
1st line: β-blockers, repeat endoscopic banding
2nd line: TIPSS
Transjugular Intrahepatic Porto-Systemic Shunt (TIPSS)
- creates artificial channel between hepatic vein and portal vein → ↓ portal pressure.
- Colapinto needle creates tract through liver parenchyma and maintained by placement of a stent.
- Used prophylactically or acutely if endoscopic therapyfails to control variceal bleeding.
Resuscitation of upper GI bleed patient
- head-down
- 100% O2
- IV crystalloid infusion up to 1L
- Bloods - FBC, U +Es (increase urea), LFTs, clotting, ABG, glucose
Medical management of variceal bleed
- terlipressin IV
- prophylactic Abx (e.g. ciprofloxacin)
Options for initiating haemostasis of a vessel or an ulcer via endoscopy
- adrenaline injection
- thermal/laser coagulation
- fibrin glue
- endoclips
Varceal bleeding management via endoscopy
Any 2 of:
- banding,
- sclerotherpay (injecting salt into vessel, causing its collapse)
- adrenaline,
- coagulation
If not: balloon tamponade or TIPSS
