Q

pathophysiology behind varies

A

o Varices form in response to portal hypertension and represent the reopening of connections
between the portal and systemic circulation
o They are most commonly seen in the distal esophagus, stomach and rectum

Q

when should screening for varices occur?

A

cirrhotics should undergo surveillance endoscopy to look for varices.
but they don’t need an endoscopy if platelets are above 150.

Q

preventing the first bleeding of esophageal varices

A

NSBB (nadolol, propanolol) or Banding
BUT: Beta blockers do not prevent the varices from FORMING. they prevent existing varices from BLEEDING.

endoscopy and banding should be done every 2-4 weeks until varices are obliterated.

Q

during an active esophageal variceal bleed, what should be given?

A
  • volume expansion (saline) and RBCs if Hb is low.
  • 7 days of antibiotics
  • octreotide bolus plus infusion 3-5 days
  • EGD for banding.
  • TIPS for uncontrolled or recurrent bleed.

16
Q

gastric varices secondary prophylaxis

A

NSBB and gluing or consider TIPS for recurrent bleeding

17
Q

portal hypertensive gastropathy

A

mosaic pattern in the stomach due to congestion (“snake-skin boot” appearance) and
may have erythema or red spots

18
Q

gastric antra vascular ectasia

A

red streaks in the antrum (“watermelon stomach”), or a more diffuse
pattern similar to PHG, and is seen with cirrhosis and connective tissue diseases

19
Q

management of Portal hypertensive gastropathy

A

NSBB, octreotide for acute bleeding, TIPS or liver transplant for refractory bleeding

20
Q

management for Gastric antra vascular ectasia

A

argon plasma coagulation (APC) or Nd:YAG laser, estrogen therapy, banding might be helpful in antrum, surgery (if not cirrhotic)

21
Q

pathophysiology of ascites in cirrhosis

A

Cirrhosis leads to portal hypertension → vasodilators (nitric oxide, carbon monoxide) are produced in response to high pressure in liver and portal circulation → vasodilators get into systemic circulation via collaterals → leads to vasodilation in the systemic circulation (hyperdynamic circulation with ↓ BP and ↑ HR) → kidneys respond to this with activation of renin-angiotensin-aldosterone system (RAAS) → sodium and water retention → worsen portal hypertension → ascites eventually is forced through the liver capsule and peritoneal lining into abdominal cavity NOTE: patients often have cirrhotic cardiomyopathy and low albumin, which contribute to ascites formation

22
Q

what must be tested when someone presents with ascites?

A

spontaneous bacterial peritonitis has a mortality of 20% and can lead to hepatic renal syndrome (must do paracentesis to confirm). SBP may be present with fever and high WBC and high creatinine

23
Q

What must you do with albumin count when someone has ascites?

A

CALCULATE SEUM ASCITES ALBUMIN GRADIENT= (albumin in serum) - (albumin in the ascites fluid)

24
Q

if ascites is due to Budd chiari syndrome, the protein is ____ and they are at ___ risk for SBP

A

high protein, low risk for SBP.

25
Q

a diagnosis of SBP would have a high ____ count

A

high neutrophil count. The culture and sensitivity would also be spiked.

26
Q

first line treatment for asictes

A
sodium restricted diet
- stop alcohol
- stop NSAIDS
- diuretics (spironolactone)
consider for liver transplant
27
Q

second line treatment for refractory asciets

A
  1. large volume paracentesis
    - consider stopping NSMM, ACE inhibitors because these can LOWER BP and thus WORSEN fluid retention.
  2. Add MIDODRINE to increase BP and facilitate renal perfusion.
  3. TIPSS (shunt), lowers portal pressure but improves renal perfusion.q
28
Q

when should you NOT do tips

A

when there’s hepatic encephalopathy. you can worsen neurological symptoms further if you have a shunt

29
Q

treatment for Spontaneous bacterial peritonitis

A

antibiotics

intravenous albumin

30
Q

definition of hepatorenal syndrom

A
  • cirrhosis with ascites
  • high serum creatinine
    -no shock
    can manifest via SBP
31
Q

type II vs type I HRS

A

o Type II = slow increase in creatinine in
patients with refractory ascites undergoing frequent LVP, which often responds to lowering diuretics
o Type I = rapid deterioration in renal
function, often precipitated by infection or
NSAIDs

32
Q

Treatment for HRS

A

midodrine to increase BP (also used as a second line ascites treatment)

  1. octreotide to lower portal pressure
  2. albumin intravenously to improve circulation.

consider TIPS. Prognosis is very poor, HRS is an indication for liver transplant.

33
Q

hepatic encephalopathy

A
Hepatic encephalopathy (HE) is a brain dysfunction caused by liver insufficiency and/or
portosystemic shunting which manifests as a wide spectrum of neurological or psychiatric abnormalities ranging from subclinical alterations to coma
34
Q

Type A, B and C causes of hepatic encephalopathy

A
o  Type (underlying disease)
  A = Acute Liver Failure   B = Portosystemic shunt   C = Cirrhosis
35
Q

treatment of hepatic encephalopathy

A
  1. lactulose (remember that this doesn’t help with acute liver failure, but will help with HE via cirrhosis). It is converted to lactic acid in colon creating acidic environment which slows NH3
    absorption
  2. antibiotics
  3. BCAAs, liver transplantation if refractory
36
Q

T/F: should restrict protein on cirrhotic patient

A

false.

37
Q

condition where ascites travels through the diaphragm

A

hepatic hydrothorax. can be complicated by infection/sbp. treat just like ascites

  1. reduce salt intake
  2. no alcohol
  3. dieuretics
  4. stop NSAIDs

2nd:

  1. paracentesis
  2. midodrine
  3. consider TIPSS
  4. consider stopping ACE inhibitors.
38
Q

T/F can use acetaminophen if cirrhotic

A

true, as long as they are not using alcohol. should avoid basis as they can cause Gi bleeding and HRS. Opioits can also accumulate and precipitate hepatic encephalopathy
