GI Flashcards
what is important to remember about dysphagia
red flag symptom - requires urgent OGD to investigate
Hx of oesophagitis
May be history of reflux/heartburn.
Patient systemically well.
Hx of oesophageal cancer
Often progresses from solids liquids
Often gives history of weight loss, anorexia, vomiting
Hx for oesophageal candidiasis
May be history of steroid use/immunocompromised e.g. HIV
Hx for achalasia
Dysphagia of both solids and liquids from the start, regurgitation (some people may do this to relieve pain)
Barium swallow – ‘bird’s beak oesophagus’
Hx for pharyngeal pouch
More common in older men
Typical symptoms include dysphagia, regurgitation, halitosis, aspiration, chronic cough
Hx for globus hystericus
Symptoms are usually intermittent.
Often have history of anxiety
Sensation of “lump in throat”
causes of upper GI bleeding
peptic ulcer
gastric erosions (due to NSAIDs)
oesophageal varices
mallory-weiss tear
which ulcer is relieved by eating and which is worseneed
Duodenal ulcers = RELIEVED by eating
Gastric ulcers = Worsened by eating
Tx for oesophageal varices
band ligation [propanolol can be given as prophylaxis of variceal haemorrhage]
what LFT results suggest hepatic causes
ALT and AST raised
what LFT results suggest biliary causes
GGT and Alk Phos raised
what is Hx of biliary colic
RUQ pain radiating to right shoulder LFTs normal (unless stone in CBD which will produce cholestatic picture)
Hx of cholecystitis
Murphy sign positive
Different from biliary colic as history of fever/raised WCC
Hx of Cholangitis (triad)
Charcot Triad
- Jaundice, Fever, RUQ pain
Raised WCC and CRP
Tx for gallstones
ERCP
what is murphy’s sign and what is it associated with
patient stops breathing when press on RUQ
cholecystitis
what is cholecystis
inflammation of gallbladder
what is Cholangitis
inflammation of bile duct
what is not seen in a cirrhotic liver
hepatomegaly
what causes hepatic encephalopathy and how can it be treated
ammonia build up
laxatives
complications of chronic liver disease
Portal hypertension (oesophageal varices, caput medusae) Ascites Encephalopathy Oedema Sepsis Clotting abnormalities Spider naevi/Gynaecomastia
causes of CLD
NAFLD PBC PSC Haemochromatosis Wilson's disease Autoimmune Hepatitis
how does NAFLD present
Usually part of metabolic syndrome e.g. obesity, type 2 diabetes, hypertension, high cholesterol
USS = steatosis
how does PBC present
90% are females, peak presentation at 50
Lethargy/itch/jaundice
Positive anti-mitochondrial antibodies, cholestatic LFTs
what are cholestatic LFTs
ALP raised markedly compared to ALT
how does PSC present
Common in men, especially those with ulcerative colitis
USS shows biliary strictures giving a ‘beaded appearance’
Increased risk of cholangiocarcinoma
Associated with pANCA
how does Haemochromatosis present
Primary (autosomal recessive) vs secondary (iron therapy/blood transfusion)
Tiredness, arthralgia, impotence, “slate-grey skin pigmentation” and “bronzed diabetic”
how does Wilson’s disease
Autosomal recessive with accumulation of copper
Present with liver disease (hepatitis, cirrhosis) and neurological/psychiatric problems (e.g. PD due to deposition in basal ganglia).
May have Kayser-Fleischer ring.
how does autoimmune hepatitis present
F>M.
Often associated with other autoimmune conditions
May present with non-specific symptoms e.g. malaise, fatigue, nausea, abdominal pain
Presence of anti-smooth muscle antibodies and elevated IgG

Giardia
Amoebiasis
who is E. Coli associated with and what is a complication of it
common amongst travellers
associated with HUS
how does campylobacter present

how does cholera present
profuse severe watery diarrhoea
describes as “rice-water” diarrhoea
associated with dehydration
how does Amoebiasis present
Profuse bloody diarrhoea and abdominal pain. May present as liver abscess –> fever, RUQ pain
