Cirrhosis is a "liver disease in which the normal microcirculation, the gross vascular anatomy, and the hepatic architecture have been variably destroyed and altered with fibrous septa surrounding regenerated or regenerating parenchymal nodules."[1]

Diagnosis

Clinical prediction rules exist to help diagnosis cirrhosis.[2] If the AST/ALT ratio ≥1 and platelet count ≤ 150,000/mm3 (Pohl's Index) then cirrhosis is very likely.[2]

Complications

Clinical practice guidelines are available for the treatment of cirrhosis and its complications.[3]

Ascites

For more information, see: Ascites.


Esophageal varices

A clinical prediction rule is available to help detect patients at risk.[4] For predicting clinically significant portal hypertension(hepatic venous pressure gradient ≥ 10 mmHg):[4]

(spider angiomas = 1 if present and 0 if absent) At a cutoff value >0.06 the accuracy is:[4]

For predicting esophagel varices:[4]

At a cutoff value >-1.02 the accuracy is:[4]

Patients with a platelet count of less than 40 and a palpable spleen are more likely to have large esophageal varices.[5]

Emergency portacaval shunt may be a better treatment than endoscopic sclerotherapy.[6]

Hepatic encephalopathy

For more information, see: Hepatic encephalopathy.


Hepatorenal syndrome

For more information, see: Hepatorenal syndrome.


Spontaneous bacterial peritonitis

For more information, see: Spontaneous bacterial peritonitis.


Spontaneous bacteremia

Spontaneous bacteremia may occur.[7][8] Mong patients with Child-Pugh Score indicating class C, half of bacteremias may not have a definite focus.[8]

Prognosis

MELD Score

For more information, see: MELD Score.

The MELD Score can help predict mortality. An online calculator is available.

Child-Pugh score

For more information, see: Child-Pugh Score.

The Child-Pugh Score can help predict mortality. An online calculator is available.
