Definitive therapy for variceal bleeding: a personal view

Definitive therapy for variceal hemorrhage has evolved during the past half century. Only completely decompressing shunts (nonselective shunts) were available before 1967. Additional options now include selective shunts, devascularization procedures, endoscopic sclerotherapy, pharmacotherapy, and hepatic transplantation. Although drug treatment is experimental at the present time, the remaining therapeutic options are applicable to various subgroups of patients and in certain clinical settings. At the University of Nebraska, patients with variceal bleeding are first grouped based on their candidacy for transplantation. Transplantation candidates with advanced (Child's class C) or symptomatic liver disease undergo transplantation as soon as possible. Future transplantation candidates with stable, asymptomatic liver disease undergo either long-term sclerotherapy or a distal splenorenal shunt if sclerotherapy fails or if they have poor access to tertiary medical care. These patients are carefully monitored so that they can undergo transplantation before they become high-operative risks. Patients who are not candidates for transplantation receive chronic variceal sclerotherapy as initial therapy so long as shunt surgery is readily available if sclerotherapy fails. When surgery is indicated, the distal splenorenal shunt is preferred to nonselective shunts because several controlled and uncontrolled series have demonstrated a lower frequency of encephalopathy after selective variceal decompression.
