The surgeon's role in the management of portal hypertension.
Patients with portal hypertension are referred to surgeons for several reasons. These include the management of continued active variceal bleeding; therapy after a variceal bleed to prevent further recurrent bleeds; consideration for prophylactic surgical therapy to prevent the first variceal bleed; or, rarely, an unusual cause of portal hypertension which may require some specific surgical therapy. Injection sclerotherapy is the most widely used treatment for both acute variceal bleeding and long-term management after a variceal bleed. Unfortunately it has probably been overused in the past. The need to identify the failures of sclerotherapy early and to treat them by other forms of major surgery is emphasized. The selective distal splenorenal shunt is the most widely used portosystemic shunt today, particularly in nonalcoholic cirrhotic patients. The standard portacaval shunt is still used for the management of acute variceal bleeding as well as for long-term management, particularly in alcoholic cirrhotic patients. For acute variceal bleeding the surgical alternative to sclerotherapy or shunting is simple staple-gun esophageal transection, whereas in long-term management the main alternative is an extensive devascularization and transection operation. Liver transplantation is the only therapy that cures both the portal hypertension and the underlying liver disease. All patients with cirrhosis and portal hypertension should be assessed as potential liver transplant recipients. If they are candidates for transplantation, sclerotherapy should be used to treat bleeding varices whenever possible, as this will interfere least with a subsequent liver transplant.
