Q
What is mesenteric ishceamia?
A
mesenteric ishceamia
- reduction in gut perfusion (small bowel)

A
mesenteric ishceamia
- central non specific abdo pain
- vomiting
- diahroea
- can lead to peritonitis and systemic sepsis
3

5
Q
Most common causes to consider for upper GI bleed?
What are important things from history that would make you think of these differentials?
A
Upper GI bleed
- most common cause is peptic ulcer disease (duodenal) NSAIDS (chronic inflammatory conditions) Hpylori
- mallory-weiss tear (wretching/vomitting)-small amounts of blood
- variceal tear (alcoholic, malignancy)-large amounts of blood)
- osphagitis/gastritis (small amounts) (epigastric pain, NSAIDS)
6
Q
How might someone with an upper GI bleed present?
A
Upper GI bleed
- Haematemesis – bright red or coffee ground (brown)
- Melaena – tar black stools, iron smell (if horrific amount in pt. w/ arterial stent, consider chance of arterio-enteric fistula!!)
- Gastritis – epigastric pain, vomiting
- Peripherally shut down – Cold, ↓CRT, ↓UO (<0.5ml/kg/hr)
- Dyspnoea (due to anaemia) – indicates large bleed
- Hypotensive <90/60 → dizzy and syncope
- Tachycardic > 100bpm (compensate for ↓BP)
- ↓GCS
- Abdo bruising
*Haematochezia – fresh blood or maroon indicates lower GI bleed
7
Q
How would you manage an upper GI bleed?
(what things in your AtoE?
what imaging?
what scores should you calculate and whats ultimate treatment?
A
AtoE assessment
- A
- Breathing -give oxygen, ABG and erect chest Xray
- Circulation
-x2 wide bore cannulas
Bloods
-Hb (may be normal as takes 30mins to fall)
-Urea ((prognostic Glasgow Blatchford score and AKI)
-LFT and coagulation (synthetic function and surgery)
-Clotting (↓Vit K)
-ABG
-Cross-match 4-6 units if Hb < 70 (1 unit for each 10g/L that Hb is less than 140g/L)
-Monitor urine output with catheter (hourly monitoring)
-ECG
- give IV 0.9% Saline or Hartmann’s (whilst waiting for blood)
- if patient deteriorating despite fluids give O Rh- blood
Disability
Environment-rectal exam -check melaena
Imaging
- erect chest X ray (pneumoperitonium)
- CT abdo and pelvis (diagnostic)
Referrals/after care
- NBM – 24h

- Secondary prevention i.e. after bleed – TIPS or endoscopic banding
10
Q
Complications of variceal bleeds?
A
Variceal bleed complications

- Aspiration pneumonia
11
Q
What is the definitive treatment for active GI bleed (non variceal) ?
A
Depends on endoscopy findings
- if high risk: achieve endoscopic heamostasis (2 or clips, cautery, adrenaline) start PPI
- if low risk: no endoscopic heamostasis required. Start PPI
SURGERY – if severe or uncontrollable bleed
12
Q
What scores are important in upper GI bleeds?
A
Glasgow Blatchford score
-need for admission and endoscopic intervention (0-1 = discharge w/ OP OGD)
Rockall score
-predicts risk of Re-bleeding and mortality post-endoscopy (higher the score, worse the mortality)
13
Q
When someone is bleeding, when do you transfuse?
when do you give FFP and when do you give platelets?
A
Transfuse
-Cross-match 4-6 units if Hb < 70 (1 unit for each 10g/L that Hb is less than 140g/L)
Giving platelets
-Give platelets if platelet count <50 x109/L.
Giving FFP
- Give FFP if active bleed and PTT or APT > 1.5x times normal

2 Oesophageal shortening pulls up the stomach (trauma)
3↑Intra-abdominal pressure Pushes stomach up
(obesity/pregnancy/ascites)

Hiatus hernia
1. Sliding (80%) – GOJ slides into thorax
↑↑↑Reflux – common as LOS becomes less competent

2. Rolling (para-oesophageal 20%)
- GOJ remains in abdo, but part of the stomach (cardia) herniates into thorax
- Dysphagia
- Reflux less common
- Chest pain
- Epigastric pain/fullness
- Nausea
29

52
What is the incubation period for hepatitis A?
14-28 days
53

| - do instead IgG, (detectable for life and determines indicates recovery-no vaccine)
54
Treatment for Hepatitis A?
Is there a vaccine?
Hepatitis A

1-6 months
57
Explain the following antigens/antibodies in Hep B.
```
HbsAg
Anti-HBc (IgG vs IgM)
Anti-HBs
HbeAg
HbeAg
```
- HbsAg (surface antigen) is present in both natural infection and vaccination 1-6 months after exposure
(if it is present >6months=chronic infection)
- Anti-HBc (core antibodies) only present in NATURAL infection - implies past infection. IgG=chonic. IgM=acute
- Anti-HBs (antibodies to surface antigen-IMMUNITY) either from exposure or immunisation. It is negative in chronic disease-because you've never beat the disease
- HbeAg -INFECTIVITY results from breakdown of core antigen from infected liver cells as is therefore a marker of infectivity
58
What are the symptoms of Hep B
Initially systemic flu-like prodrome:
- Fever (mild)
- Malaise (profound)
- Anorexia+ Nausea
- BONE ACHE AND ITCH Arthralgia + Uticaria (COMMON)

→ dark urine → pale stools
-Fulminant hepatitis (liver failure within 8 wks)
-Might reveal decompensated liver disease – ascites, encephalopathy, GI haemorrhage
59
Treatment for Hepatitis B?
Treat if ALT >30 or HBV DNA>2000
Pegylated interferon alfa-2a = first-line (SE:↓WCC, ↓Plt)

Investigations for hepatitis C
1. Anti-HCV antibodies confirm exposure 3 months after infection (either had or have)
2. If positive, do reflex testing with PCR
3. If PCR is positive, it confirms ongoing infection/chronicity so do a liver biopsy to assess damage and need for treatment
(Also, test to determine the HCV genotype)
64

- All patients treated
- Nucleoside analogues (now generally preferred) e.g. sofosbuvir
(used to have to takepegylated interferon SC weekly and a pill)
65
What is hepatitis D?
How do you test for it?
Whats the treatment?
- Hep D is an incomplete RNA virus (needs Hep B-Hep B vaccination also protects for Hep D)
- If HBsAg +ve → check Anti-HDV Ab
-Treatment: interferon doesn't really work=may need transplant
66
How is hepatitis E spread?
Tests?
Treatment?
Hep E (similar to hep A)
- Fecal oral
- Consumption of pork/shellfish/molluscs
Tests:
- DIAGNOSTIC is HEV serology (∆)

What is hepatorenal syndrome?
Why is renal failure a complication of liver disease??
Hepato-renal syndrome = Cirrhosis + Ascites + Renal failure
Why: ↓Hepatic clearance of immune complex leads to accumulation in kidney → IgA nephropathy and hepatic glomerulosclerosis
If HCV → Mesangiocapillary/membranoproliferative glomerulonephritis
87
What immunoglobulins are assosiated with what conditions? (IgA, IgM, IgG,
Immunoglobulins
IgA = alcohol
IgM = PBC
IgG: autoimmune hepatitis (if ANA/SMA/SMA) or PCS (if ANCA)
-all 3: cirrosis
88
```
What auto antibodies are assosiated with what conditions?
ANA/SM
LKM
AMA
ANCA
```
```
Auto antibodies
ANA/SM: Autoimmune type 1 (or PSC)
LKM: AI type 2 (only in children)
AMA (M2): PBC
ANCA: PSC
```
89
Obstructive picture, 'beads on a string' sign and assosiated with IBD?
Primary sclerosing cholangitis
- beads on sting sign found on ERCP
- assosiated with Ulcerative colitis
- increased risk of cholangiocarcinoma

```
Triad of:
1. abdo pain
2. hepatosplenamegally
3. ascites

treatment?
assosiated with?
Budd chiari syndrome (acute hepatitis)
- investigations: urgent USS with doppler
- treatment: treat as any DVT
- assosiated with polycythemia vera (too many RBC)
(acute version of portal vein thrombosis)
91
Therapeutic Paracentesis
- what would make you think SBP?
- what would make you think underlying malignancy
Therapeutic Paracentesis (WCC, RBC, gram stain)
SBP = Neutrophil > 250 cells/mm
high RBC = suspicious of underlying malignancy e.g. HCC
Albumin/protein level
Exudate > 25 g/L; transudate < 25g/l
SAAG (serum ascites-albumin gradient) = serum alb conc – ascetic alb conc
≥ 11 g/L (transudative– cirrhosis, HF, CCF)
<11 g/L (exudative –malignancy, infection, pancreatitis, nephrotic syndrome)
Withdrawal of ≥ 5L may cause post-paracetesis circulatory dysfunction (PPCD) AKI
92
Exudative vs transmutative ascites?
(SAAG high or low)
(causes)
Transudate (portal vein pressure)
-high SAAG (>1.1g/dL) (liver cirrhosis/heart failure
Exudate < 25g/l
- low SAAG (<1.1g/dL)
- local disease
- inflammation or malignancy (or pancreatitis/nephrotic syndrome)
93
Why do you get portal HTN in chronic liver disease?
| What are some signs of portal HTN? (4)
PORTAL HTN
Fibrosis → ↑intrahepatic resistance→ Porto HTN and shunt to other veins
```
Effect of portal HTN
-oesophageal varices (haematemesis)
-gastric varices (melena)
-heamorroids (rectal veins)
-transudative ascites
-caput medusae – paraumbilical/epigastric veins
-congestive splenomegaly
-hypo perfusion of kidneys→ water/salt retention >transudative pleural effusion
>↑CO
```
94
Pre hepatic/intrahepatic/post hepatic causes of portal HTN?
PORTAL HTN
Prehepatic
• Portal vein thrombosis
• Splenic vein thrombosis
```
Intrahepatic
• Cirrhosis
• Schistosomiasis
• Hepatic metastases
• Hepatic sinusoidal obstruction syndrome (aka hepatic veno-occlusive disease)
```
Post-hepatic
• Budd-Chiari syndrome - hepatic vein obstruction
• Right-sided heart failure
• Constrictive pericarditis
95
1st line treatment for portal HTN?
PORTAL HTN
Propanolol (non-cardiac selective beta-blocker) - first-line treatment
Inhibits beta-2-adrenergic receptors in the GI tract>vasoconstriction>decrease portal and collateral blood flow>reduces portal hypertension
96
What is an invasive management option for certain patients with portal hypertension?
Trans-jugular intrahepatic portosystemic shunt (TIPSS)
An artificial channel connecting inflow portal vein and the outflow hepatic vein
97
Common indications for TIPSS surgery?
Secondary prophylaxis for oesophageal variceal bleeding
Treatment of refractory ascites
Treating portal hypertension in Budd-Chiari syndrome
98
When would you give prophylactic AB for SBP?
NICE recommend: 'Offer prophylactic oral ciprofloxacin or norfloxacin for people with cirrhosis and ascites with an ascitic protein of 15 g/litre or less until the ascites has resolved'
also if people have PMH of SBP
