Abstract
Injection sclerotherapy is the most widely used definitive treatment of acute variceal bleeding and is increasingly performed at the time of the first emergency endoscopy. Direct endoscopic ligation of varices by banding is a new technique under evaluation for both acute bleeding varices and long-term management. Repeated injection sclerotherapy is one of the major options for long-term management after variceal bleeding. More major surgical procedures are usually reserved for the failures of sclerotherapy in the management of acute variceal bleeding, whereas portosystemic shunts, particularly the distal splenorenal shunt, or an extensive devascularization and transection operation are commonly used alternative forms of therapy in long-term management. All patients with variceal bleeding should be assessed for liver transplantation, although only a few will ultimately receive a liver transplant. Medication with propranolol is widely recommended in long-term management, but its use in this context remains controversial. The most controversial area of management is prophylactic treatment before variceal bleeding. Major surgical procedures and injection sclerotherapy are not justified at present because it is difficult to identify those patients with a high likelihood of a first variceal bleed. Although medical therapy with propranolol has proved the most successful therapy to date, a case is made for treating most patients conservatively until their first variceal bleed occurs or until better predictive indices for patients at high risk of a first bleed are identified.
