e. None of the above
About two-thirds of patients with portal hypertension develop varices; of these only two-thirds subsequently experience variceal hemorrhage. A number of factors are important in the pathogenesis of variceal hemorrhage. These include portal pressure, intravariceal pressure, variceal size and structure, and other factors. Variceal size alone is not predictive of variceal hemorrhage. Evidence conflicts about whether erosive esophagitis is a cause of variceal rupture. Control of acid reflux by H2 blockade has not been shown to decrease the incidence of rebleeding after esophageal hemorrhage.
