The distal splenorenal shunt.

Distal splenorenal shunt (DSRS) provides selective decompression of gastroesophageal varices, with maintenance of portal hypertension and prograde portal flow to the cirrhotic liver. Accurate patient evaluation is essential to select appropriate patients for DSRS. Variceal bleeding control is greater than 85% and is as effective as total portosystemic shunts. Maintenance of prograde portal flow is greater than 90% in nonalcoholic disease, but only 50% in alcoholic cirrhosis; the latter is improved by total splenopancreatic disconnection. Hepatic function is better maintained when portal flow is maintained. Encephalopathy is lower after DSRS than after total shunts. Survival is not significantly improved after DSRS in patients with alcoholic cirrhosis compared to outcome after total shunts. The survival in patients with nonalcoholic disease is significantly improved over that of alcoholics.
