Variceal hemorrhage

Reducing morbidity and mortality from esophageal varices remains a challenge for physicians managing patients with chronic liver disease. For patients who have never bled from varices, prophylactic therapy with nonselective beta-blockers reduces the risk of initial variceal bleeding and bleeding-related death. Thus, patients with newly diagnosed cirrhosis should be considered for endoscopic variceal screening. All patients with Child’s class B and C cirrhosis should be offered endoscopic screening, whereas those with Child’s class A with evidence of portal hypertension (eg, platelet count less than 140,000 per milliliter, portal vein diameter larger than 13 mm, evidence of splenic varices on ultrasound) should be screened. The principal risk factors for variceal bleeding are variceal size, the presence of color changes on the variceal wall (indicative of decreased wall thickness), and degree of liver dysfunction. Patients with moderate or large sized varices and those with varices exhibiting color changes (eg, red wale marks, cherry red spots) should be treated with beta-blockers. Individuals without varices and those with small varices should undergo repeat endoscopy at approximately 2-year intervals. Patients unwilling or unable to take beta-blockers do not need to be screened. For patients with acute variceal bleeding, the combination of pharmacologic therapy plus endoscopic therapy is superior to either therapy alone. Octreotide is the drug most often used as initial therapy in the United States. Terlipressin is the preferred agent; however, it is not available in the United States. Endoscopy is performed as early as possible, and endoscopic injection sclerotherapy or endoscopic variceal band ligation is employed if variceal bleeding is confirmed or suspected. Endoscopic therapy should be repeated until the varices are obliterated completely. The addition of beta-blockers to endoscopic sclerotherapy or ligation may decrease the rate of rebleeding compared with receiving endoscopic treatment alone. Patients with bleeding refractory to combined medical plus endoscopic therapy should be considered for transjugular intrahepatic portosystemic shunts or shunt surgery.
