Upper GI Bleed Flashcards
Understand the definition,etiology, presentation and management
What is upper GI Bleed
Bleeding from the GI tract where the source of bleeding is proximal to the duodenal-jejunal flexure/ligament of treitz
Non-variceal bleed causes (4)
- Peptic ulcer
- Acute abdominal lesions: gastritis and stress ulcers
- Mallory Weis tears
- Tumors : gastrointestinal stromal tumor
Obscure causes of Upper GI bleed (4) and Miscellaneous causes
Cameron ulcers
Haemobilia
Aorto enteric fistulas
Clotting abnormalities
Miscellaneous:
Pharynx : nose bleeds , hemoptysis and naso/oropharyngeal lesions
RUQ pain, jaundice and upper GI bleed
Haemobilia
What are the 3 specific features of upper GI bleed
- Haematemesis
- Coffee ground vomiting
- Melaena
Mention 5 specific measures taken in patients with suspected variceal hemorrhage
- Antibiotic prophylaxis for spontaneous bacterial peritonitis
- Recombinant factor Vll
- Lactulose
- Monitor blood glucose
- Give Thiamine in alcoholics
What’s the indication for emergency surgery without further diagnostic evaluation and where is it contraindicated
- Massive upper GI bleed unless the oesophageal varices are suspected as the probable cause of bleeding
What are 6 points that are important on history and examination
- Evaluate for symptoms of PUD ,as well as it’s risk factors
- Examine the pt for stigmata of chronic liver disease
- Examine the pt for signs of portal HPT
- Evaluate the pt for signs of metastatic stomach cancers
- Perform a rectal exam to evaluate the appearance of blood
- Ask specifically about clotting abnormalities and warfarin therapy
Which subgroup of patients is more prone to dying from bleeding
- Older than 60 yrs
- Cardiac,pulmonary, liver or renal disease
- Severity of bleeding episodes : haematemesis, Hb less than 8 and shock with BP less than 100
When can an upper GI endoscopy be done as an emergency
- If oesophageal varices are suspected
2. Signs of ongoing bleeding
What are the four endoscopic treatment modalities:
- Injection : adrenaline with saline, sclerosant
- Mechanical : rubber band ligation
- Thermal: laser
- Topical : collagen
How should patients with stigmata for rebleeding be treated?
-Ideally with two endoscopic modalities followed by high dose of proton pump inhibitors
Who benefits from Endoscopic treatment? And who does not
- patients with active bleeding or if there is a visible vessel will benefit And
- patients with minor stigmata for rebleeding or clean ulcer base do not benefit
What are the indications for surgery
- Massive bleeding
- Continuous bleeding
- Rebleeding to shock
- Older patients with higher risk of mortality and strong stigmata for rebleeding on endoscopy
What sclerosants do we give for oesophageal varices? And what do we use for varices in the stomach
- Ethanolamine olate
- STD : sodium tetradecyl sulphate
And we use cyano achrominate glue because rubber band cannot work since the mucosa of the stomach is not pliable
