Abstract:
:Effective control of variceal rebleeding (secondary prophylaxis) or prevention of the initial bleeding (primary prophylaxis) are the main objectives of the treatment of portal hypertension. Endoscopic sclerotherapy is the treatment of choice for secondary prophylaxis, since it significantly decreases rebleeding and, to some extent, mortality. A combination of propranolol and sclerotherapy may be of benefit by decreasing postsclerotherapy rebleeding. Endoscopic variceal band ligation and transjugular intrahepatic shunt are emerging as useful alternative techniques. Devascularisation and preferably selective shunts should be reserved for use as salvage of sclerotherapy failures. Liver transplantation, if feasible, could become the ultimate therapy by controlling variceal bleeding and improving hepatic function. Pharmacotherapy, while not very successful for secondary prophylaxis, has shown promise for primary prophylaxis of variceal bleeding. Nonselective beta-blockers significantly decrease the rebleeding rates but are associated with only marginal survival benefits. beta-Blockers alone cannot decrease the hepatic venous pressure gradient adequately (to less than 12mm Hg). Combination with nitrates and other drugs may prove beneficial and requires clinical evaluation. Endoscopic sclerotherapy and surgery have little role in primary prevention of variceal bleeding in patients with cirrhosis but need evaluation in noncirrhotic patients.
