Abstract
A switch to decompressive shunt procedures is mandatory if endoscopic therapy fails to control recurrent variceal hemorrhage. Surgical shunt procedures continue to be safe, highly effective, and durable procedures to treat variceal bleeding in patients with low operative risk and good liver function. In cirrhotics, elective operations using portal flow preserving techniques such as a selective distal splenorenal shunt (Warren) and a partial portocaval small diameter interposition shunt (Sarfeh) should be preferred. Rarely, end-to-side portocaval shunt may serve as a salvage procedure if emergency endoscopic treatment or transjugular intrahepatic portosystemic shunt insertion fails to stop bleeding. Until definitive results from randomized trials are available patients with good prognosis (Child-Pugh A and B) should be regarded as candidates for surgical shunts. For patients with noncirrhotic portal hypertension, in particular with extrahepatic portal vein thrombosis, portosystemic shunt surgery represents the only effective therapy which leads to freedom of recurrent bleeding and repeated endoscopies for many years, and improves hypersplenism without deteriorating liver function or encephalopathy. Gastroesophageal devascularization and other direct variceal ablative procedures should be restricted to treat endoscopic therapy failures without shuntable portal tributaries.
