Overview

Medical Therapy

Medical therapy for gastrointestinal varices should include management of the underlying cause of portal hypertension and specific therapy for varices after they have developed.

Treatment of underlying causes

Alcoholic liver disease

For a detailed description for treatment of alcoholic liver disease, click here.
  • Mild to moderate alcoholic hepatitis:
    • Abstinence from alcohol
    • Preferred regimen (1): Aggressive enteral nutrition therapy
  • Severe Alcoholic hepatitis:
    • Preferred regimen (1): Four week course of prednisolone (40 mg/day for 28 days), typically followed by discontinuation or a 2-week taper (if no contraindications for steroid use).
    • Preferred regimen (2):Pentoxifylline therapy (400 mg orally 3 times daily for 4 weeks) is an alternative in severe disease, especially if there are contraindications to steroid therapy

Hepatitis C

For a detailed description for treatment of Hepatitis C, click here[1][2][3][4][5][6]

Genotypes HCV 1 and 4

  • Preferred regimen (1): Peginterferon plus ribavirin for 48 weeks. The dose for peginterferon alfa-2a is 180 µg subcutaneously per week together with ribavirin using doses of 1,000 mg for those <75 kg in weight and 1,200 mg for those >75 kg; the dose for peginterferon alfa-2b is 1.5 µg/kg subcutaneously per week together with ribavirin using doses of 800 mg for those weighing <65 kg; 1,000 mg for those weighing >65 kg to 85 kg, 1,200 mg for >85 kg to 105 kg, and 1,400 mg for >105 kg.[7]

Genotypes HCV 2 and 3

Hepatitis B

For a detailed description for treatment of Hepatitis B, click here[9][10][11][12][13][14][15][16][17][18][13]
a. ALT greater than 2 times normal or moderate/severe hepatitis on biopsy, and HBV DNA >20,000 IU/mL - treatment may be initiated with any of the 7 approved antiviral medications, but pegIFN-α, tenofovir or entecavir are preferred.
b. ALT persistently normal or minimally elevated (<2 times normal) - should not be initiated on treatment.
c. Children with elevated ALT greater than 2 times normal - treatment may be initiated with IFN-α or lamivudine if ALT levels remain elevated at this level for longer than 6 months.

Autoimmune hepatitis

For a detailed description for treatment of autoimmune hepatits, click here.

Primary biliary cirrhosis

For a detailed description for treatment of primary biliary cirrhosis, click here.

Primary sclerosing cholangitis

For a detailed description for treatment of primary sclerosing cholangitis, click here.

Wilson's disease

General considerations and disease stratification

The management of gastrointestinal varices in chronic liver disease should be tailored according to the clinical stage of liver disease and cirrhosis. The following table outlines the key stages of chronic liver disease and the treatement goals for the respective stage:

Disease stage HPVG Varices Complications of portal hypertension Management goals
Compensated liver disease Less than 10 mmHg - -
Greater than equal to 10 mmHg - - Prevent decompensation
Greater than equal to 10 mmHg + - Prevent decompensation
Decompensated liver disease Greater than equal to 12 mmHg + Acute variceal bleed Control bleeding, prevent early rebleeding and death
Greater than equal to 12 mmHg + Previous variceal hemorrhage without ascites or encephelopathy Prevent further decompensation (further bleeding, ascites and encephelopathy)
Greater than equal to 12 mmHg + Prior variceal hemorrhage with ascites and/or encehelopathy Prevent further decompensation and death

Goal-directed management

The management of gastrointestinal varices is aimed at optimizing the following:[23][24]

  • Portal venous inflow
  • Portal resistance
  • Portal pressure

This is achieved through the following pharmacological therapies:[25][23]

  • Splanchnic vasoconstrictors:
    • Vasopressin and analogues
    • Somatostatin and analogues
    • Nonselective β-blockers
  • Venodilators:
    • Nitrates

The following table shows the major mechanism affected by the various pharmacological therapies used in the management of varices:

Major pharmacological therapy Portal flow Portal resistance Portal pressure
Vasoconstrictors (e.g. β-blockers) ↓↓
Venodilators (e.g. nitrates)
Endoscopic therapy
TIPS/Shunt therapy ↓↓↓ ↓↓↓

Small non-bleeding varices

Large non-bleeding varices

3 Acute hemorrhage

  • 3.1 Adult
    • Preferred regimen (1): Vasopressin continuous IV infusion of 0.2–0.4 units/minute that can be increased to a maximal dose of 0.8 units/minute. It should always be accompanied by IV nitroglycerin at a starting dose of 40 µg/minute, which can be increased to a maximum of 400 µg/minute, adjusted to maintain a systolic blood pressure >90 mmHg
    • Preferred regimen (2): Telipressin initial dose of 2 mg IV every 4 hours and can be titrated down to 1 mg IV every 4 hours once hemorrhage is controlled
