Overview
The gold standard diagnostic test for cirrhosis is liver biopsy, although it is rarely necessary for diagnosis or treatment. NT-proBNP can be used to evaluate the complications of cirrhosis.
Other Diagnostic Studies
Liver Biopsy
- The gold standard for diagnosis of cirrhosis is liver biopsy, through a percutaneous, transjugular, laparoscopic, or fine-needle approach.
- Histologically, cirrhosis may be classified as micronodular, macronodular, or mixed, but this classification is nonspecific to the etiology.
- Histology of the liver may change as the disease progresses, and serological markers are much more specific, however, a biopsy is not necessary if the clinical, laboratory, and radiologic data suggest cirrhosis.
- There is a small but significant risk of liver biopsy, and cirrhosis itself predisposes for complications due to liver biopsy.[1]
- Alcoholic liver disease : Liver biopsy may show hepatocyte necrosis, presence of mallory bodies, neutrophilic infiltration and perivenular inflammation.
- Primary biliary cirrhosis : Gold standard diagnosis is antimitochondrial antibodies with liver biopsy as confirmation if showing florid bile duct lesions.
Endoscopic retrograde cholangiopancreatography
- diagnosis of sclerosing cholangitis
Liver biopsy: [2][3][4][5][6][7][8][9]
- Cirrhosis is primarily a histological diagnosis.
- Percutaneous liver biopsy remains the cornerstone of diagnosis.
- quick and simple to perform in a cooperative patient with a normal INR and platelet count.
- The gold standard for diagnosing cirrhosis is:
- Examination of an explanted liver, either at autopsy or following liver transplantation, because the architecture of the entire liver can be appreciated.
- Sample of the liver is obtained by:[12]
- Percutaneous
- Transjugular
- Laparoscopic radiographically-guided fine-needle approach.
- Liver biopsy is not necessary if the clinical, laboratory, and radiologic data strongly suggest the presence of cirrhosis and if the results would not alter the patient's management.
- Patient with a history of heavy alcohol use who has ascites, severe coagulopathy, and a shrunken, nodular-appearing liver on ultrasonography.
- Liver biopsy may be suggestive of etiology:
- Metabolic causes of cirrhosis include:
- Hereditary hemochromatosis
- Nonalcoholic steatohepatitis
- Wilson disease
- Alpha-1 antitrypsin deficiency
- Risks:
- haemorrhage
- biliary peritonitis
- haematoma
- perforation of other viscera
- mortality rates of between 0.01% and 0.1%
- Percutaneous biopsy of focal lesions may be performed in combination with either ultrasound or CT imaging.
- Prerequisites:
- normal INR and platelet count.
- May be performed in combination with either ultrasound or CT.
- Patients with moderate coagulopathy:
- Plugged liver biopsy : injection of gelatin sponges or metal coils down the tract after biopsy
- Laparoscopic liver biopsy performed on a sedated patient with moderate coagulopathy
- Advantage: allows direct visualisation of the liver
- Patients with severe clotting disorders:
- Transjugular liver biopsy :
- risk of intraperitoneal bleed is less
- Disadvantages:
- biopsies are small: multiple biopsies required
- taken 'blindly'
NT-proBNP (N Terminal pro Brain Natriuretic Peptide)
- N Terminal pro Brain Natriuretic peptide is an important factor for evaluating the complications of cirrhosis.[13]
- High levels of NT-proBNP ( >101 pg/ml) is the marker of esophageal varices.
- NT-proBNP is not a marker of cirrhosis progression.

The main cause of mortality after percutaneous liver biopsy is intraperitoneal haemorrhage as shown in a retrospective Italian study of 68,000 percutaneous liver biopsies in which all six patients who died did so from intraperitoneal haemorrhage. Three of these patients had had a laparotomy, and all had either cirrhosis or malignant disease, both of which are risk factors for bleeding.
